We are not even in a bull market yet. Usually these things happen when there is a lot of hype. ZigmaBit is scammer company with fake mining rigs to basically scam you. Their selling website is https://zigmabit.com/ , please don't even click the link. We do not want to give them any traffic, just watch the video down below.
They have listed 3 miners on their website:
  • ZigBit 2.0
  • ZigBit 3.0
  • ZigBit 5.0

https://preview.redd.it/406xtn2l3cb41.jpg?width=1676&format=pjpg&auto=webp&s=4933fa05a303be6ece49fa37c4e8845fa8636605
Which of course doesn't exist. They recommend that these miners will make some crazy gains, which of course will not happen. As these miners are fake. Seeing the specification makes me think these guys know very little about crypto currency mining. So for example the specification they are advertising on ZigBit 5.0 is :
  • Bitcoin-2000 TH/s
  • Litecoin-300 GH/s
  • Ethereum-75 GH/s
  • Dash-50 TH/s
  • Power Consumption-2400W
  • Power Socket 110V-240V
Now you understand what im talking about, seriously 2000 TH/s mining Bitcoin at 2400w (where the latest Antminer S17 is 72Th/s), or mining ETH and the profit is so big that it will cover the miner cost faster then month. And another thing, they using the same hardware to mine multiple currencies which every one of them needs different hardware. Worst thing is that people will loose money, and most likely some of them already did. People think they will get rich after buying this miner, which they will never receive. Their fake products look so bad, their cheapest version ZiBit 2.0 looks like an ATX power supply.

Few things to also note is :
  • They have support chat on their website. I did send them a message and got response after about 20 minutes. So they told me that they only accept crypto currency, and the products are shipped from United Kingdom. My last line of the chat was "im coming for you you'll be in jail soon ".
  • When you google miner name, there is few websites coming up describing how great is their product. This most likely is owned websites for this scammer or this is purchased content posts.
  • Last thing is that i tired to do checkout on one miner, there is btc address which has already received 7btc. Im not sure if this is some people got already scammed or this is fake volume, hope this is fake volume https://www.blockchain.com/btc/address/1C4RSshoK9veR4jCNStqF32QARS5oGnmzw . Hope none is scammed.
Sad to see that there is such kind of people who makes money on scamming others. Man karma is there , i believe it will come for you sooner or later.

Frequently Asked Questions

NOTICE

This post is a temporary resting place for FAQs while we wait for the release of VertDocs.

What is Vertcoin?

Vertcoin is a digital peer to peer currency focused on decentralization and ASIC resistance. Vertcoin is aiming to be easily accessible to the everyday user without extensive technical knowledge. Vertcoin has started to lower the barrier of entry with lots of video guides and the development of the One Click Miner (OCM).

Why does ASIC Resistance Matter?

ASICs (Application Specific Integrated Circuits) are dedicated mining devices that can only mine one algorithm. Coins like Bitcoin and Litecoin both made GPU mining obsolete when SHA-256 and Scrypt ASICs were created.
ASIC Resistance and How it Makes Vertcoin Decentralized
Vertcoin believes that ASIC resistance goes hand in hand with decentralization.
ASICs are made by companies like Bitmain and almost all the original sellers of ASICs sell on a preorder basis. When pre ordering an ASIC you are buying from a limited batch that the ASIC company has produced. Often times the batch will not be fully filled and the ASIC company will often have left over ASICs. When the ASIC company has left over ASICs they will put them to work mining. Soon enough the ASIC company will have a very large amount of unsold ASICs that are mining and slowly the ASIC company starts to own a large part of the network’s hashrate. When an ASIC company(s) starts to own a large majority of the hashrate the network can become very centralized after a while.
Having your network consist of a few large companies can be very dangerous as they could eventually get 51% hashing power and 51% attack your network, destabilizing the network. When your network is made out of a lot of smaller miners, like Vertcoin, it is much harder for your network to be 51% attacked, therefore increasing network security. By having centralized hashing power your coin effectively centralizing the network as the centralized hashing power can deny transactions and stop any activity they don’t want.

What Ways is Vertcoin Superior to Litecoin and Bitcoin?

Network Difficulty Adjustments with Kimoto Gravity Well
Vertcoin uses a difficulty adjustment called Kimoto Gravity Well which adjusts the difficulty every block, whereas Bitcoin and Litecoin’s difficulty changes every 2016 blocks. By adjusting the difficulty every block Vertcoin’s block time can stay consistent by adjusting for the fluctuation in network hash rate from hash rate renting and part time miners. If a large miner switches off Bitcoin or Litecoin mining the network could be slowed to a crawl until 2016 blocks are mined and the difficulty can change to adjust for the new network hash rate. We observed this happen to Bitcoin when Bitcoin Cash became more profitable than Bitcoin and Bitcoin’s network hash rate saw a steep fall off, slowing the network to a crawl. If this was to happen with Vertcoin the difficulty would adjust after 1 block was mined, allowing Vertcoin to always be profitable to mine.
Anyone can Meaningfully help Verify Transactions
In Proof-of-Work crypto currencies miners help secure the blockchain and get rewarded with the block reward. In ASIC mineable coins like Bitcoin and Litecoin you can’t meaningfully verify transactions unless you pay 1000-2000$ for a ASIC miner. When you mine with a CPU or GPU in a ASIC mineable coin you make no meaningful impact on the network. It is like trying to break concrete with a shovel while everyone else has a jackhammer.
Simple Upgrades Aren’t Held back by 1-2 Large Miners
In ASIC market people buy ASICs in batches in a preorder. With Bitcoin ASICs there is not enough demand for ASICs so the batch often doesn’t get sold out so now the manufacturer has spare ASICs. Now that the manufacturer has spare ASICs they will often start mining with them and eventually the ASIC company has one of the highest hash rates. If the ASIC company doesn’t want a certain upgrade to go through, for example SegWit, they can vote with their hash rate to hold back the upgrade forever or at least until people who want SegWit get more hash rate.
You Have a Say in Protocol Rules and Consensus
In Bitcoin you are a passive observer because you can only issue transactions and you have no part in the process after that. In Vertcoin you can be apart of the process for deciding the ordering of transactions and deciding what transactions get into blocks.
Block Rewards and Transaction Fees are Distributed Evenly
In Bitcoin and Litecoin the block rewards and transaction fees are often given to the large miners in China due to mining centralization created by ASICs. Vertcoin distributes its mining rewards to people all around the world thanks to the mining decentralization.

When will Atomic Swaps Be Ready?

Atomic Swaps can be done in two flavors: On-chain and Off-chain (via Lightning Network). On-chain swaps were actually done already using Blocknet, you can see it in use on Youtube. We're looking into doing it again using Interledger.
However our main focus is to do off-chain Atomic Swaps using Lightning Network technology. Because it has the same benefits as Lightning transactions: No network fees and instant transactions.
For off-chain swaps we need Lightning Network to be fully operational. It's difficult to give an ETA on that since we aren't the ones developing it. U/gertjaap posted a video on the current state of the Lightning Network for Vertcoin a while ago, which you can see here.
This was actually the "bleeding edge" of Lightning Network at the time. was able to use it on VTC's main net, meaning that our blockchain is ready for the good stuff. As you can see however, it can't yet be considered production ready (most users would want a little better UX than a command line app).
Now off-chain Atomic Swaps is a technique based on the same principles as Lightning Network, but adds an extra complexity for it being across chains. So it's basically the same as a "multi hop" Lightning payment, which is not yet built by any of the implementations. They're still working hard on making the single-hop payments robust. So in order for AS to be possible, LN has to be fully operational.
A timeline cannot be given at this time, because frankly we don't know. The implementation of Lightning Network we feel has the most potential is LIT, because it supports multiple currencies in its protocol (where LND is bitcoin-only at the time and requires significant work to support other currencies, which is an essential part of being able to work across multiple blockchains).
LIT is open source and there's nothing secretive about its progress, you can see the development on Github. We even have our lead dev James Lovejoy (u/jamesl22) close to the action and contributing to it where possible (and our team as well through testing it on the Vertcoin chain).
So we're not developing LN or AS ourselves, we're just ready with our blockchain technology whenever it becomes available.
If we have any real progress that has some substance, you can expect us to let the world know. We're not interested in fluffy marketing - we post something when we achieve real progress. And we are not keeping that secret.

How do I Choose the Right Vertcoin Wallet?

Deciding what Vertcoin wallet you should choose can be a difficult process. You can choose between three different wallets: Core, Electrum and Paper. Once you decide you can use the "How to Setup Your Vertcoin Wallets" video guide to assist you.

Core

The Core wallet is the wallet that most people should use. It will store the entire blockchain (~2GB) on your computer. The Core wallet is the only wallet that fully supports P2Pool mining. You will also have to use the Core wallet if you plan to run a P2Pool node or any Vertcoin related server.

Electrum

The Electrum wallet is a light wallet for Vertcoin. You do not have to download the blockchain on your computer, but you will still have your own private keys on your computer. This is recommended for people who don't need to store Vertcoins for very long and just need a quick but secure place to store them.

Paper

The Paper wallet is as the name implies, a physical paper wallet. When generating a paper wallet you will get a pdf that will need to print out. A paper wallet is normally used for long term storage since it is the safest way to store Vertcoins. A paper wallet can also be called "cold storage." Cold storage references the storage of your coins offline, preventing you from getting hacked over the internet.

Ledger Nano S

The Ledger Nano S is a hardware wallet designed by Ledger. A hardware wallet is similar to a paper wallet since it is normally used for cold storage. The hardware wallet is on par with the security of a paper wallet while being easy to use and setup. Note: You should never mine directly to a Ledger hardware wallet.

How do I start mining Vertcoin?

We have many guides available for you to use depending on your computer specifications.
Nvidia GPUs on Windows
Nvidia GPUs on Linux
AMD GPUs on Windows WARNING: Very unprofitable, AMD optimized miner is coming very soon.

Where can I get the One Click Miner (OCM)

You can get the latest version of the One Click Miner in the Vertcoin Discord. The download is pinned to the top of the #oneclick channel.

What do all the Numbers Mean on P2Pool’s Web Interface

I've seen a lot of confusion from new miners on public p2pool nodes, so here's a primer for the most common static node page style, for first time miners: https://imgur.com/K48GmMw

Active Miners on this Node

Address - This is the list of addresses currently mining on this node. If your address does not show up here, you are not mining on this node.
Hashrate
This is a snapshot of your hashrate as seen by the node. It will fluctuate up to 15% from the hashrate you are seeing on your mining software, but will average out to match the output in your mining software.
Rejected Hashrate
This is the amount of your hashing contribution that is rejected, both in hashrate and as a percentage of your total contribution. Running your own p2pool node minimizes this number. Mining on a node that is geographically close to reduce lag also minimizes this number. Ideally you would like it to be less than 1%, but most people seem happy keeping it under 3%.
Share Difficulty
This speaks for itself, it is the difficulty of the share being currently worked on. Bigger numbers are more difficult.
Time to Share
This is how long you need to mine before you will receive any payouts, or any "predicted payout." The lower your hashrate, the higher your time to share.
Predicted Payout
This is the reward you would receive if a block was found by p2pool right now. If it reads "no shares yet" then you have not yet been mining the requisite amount of time as seen in the previous "time to share" column.

Status

Network Hashrate
This is the total hashrate of all the miners mining vertcoin everywhere, regardless of where or how.
Global Pool Hashrate
This is the total hashrate of all the miners mining vertcoin on this p2pool network, be it the first network or the second network.
Local Pool Hashrate
This is the total hashrate of all the miners mining Vertcoin on this node.
Current Block Value
This is the reward that will be given for mining the current block. The base mining reward is currently 50 VTC per block, so any small decimal over that amount is transaction fees being paid by people using the network.
Network Block Difficulty
This is the difficulty of the block being mined. The higher the number, the higher the difficulty. This number rises as the "Network Hashrate" rises, so that blocks will always be found every 2.5 minutes. Inversely, this number falls when the "Network Hashrate" lowers as well.
Expected Time to Block
This is a guess at how much time will elapse between blocks being found by this p2pool network. This guess is accurate on average, but very inaccurate in the short term. Since you only receive a payout when the network finds a block, you can think of this as "Estimated Time to Payout."

Why is P2Pool Recommended Over Traditional Pools?

Decentralisation

P2Pool is peer to peer allowing a decentralized pool mining system. There are many nodes setup around the world that connect to each other too mine together. Many other coins have 1 very large pool that many miners connect to and sometimes the largest pool can have 51% or more of the network hash rate which makes the network vulnerable to a 51% attack. If P2Pool is the largest network then that prevents the Vertcoin network to be susceptible to a 51% attack as P2Pool is decentralized.

PPLNS Payout System

P2Pool uses a PPLNS (Pay Per Last N Shares) payout system which awards miners more the longer they mine, sort of like a loyalty system. A drawback to this system is that part time miners that aren't 24/7 won't be able to earn that much.

2 Networks

While Network 1 is catered towards 24/7 miners and people who have dedicated mining rigs, Vertcoin has a second P2Pool network where part time miners and miners under 100 MH/s can go to mine.

Mines Directly to Your Wallet

P2Pool mines directly to your wallet and cuts out the middleman. This reduces the likely hood that the pool will run away with your coins.

No Downtime

Since P2Pool is decentralized and has different nodes for you to choose from there will be no downtime because the P2Pool network does not die if one node goes down. You can setup a backup server in your miner so that you will have no downtime when mining.

Anonymity and Security

When using P2Pool you use a wallet address making your real identity anonymous, you are simply known by a random 34 letter string. Along with using a wallet address instead of a username there is no password involved P2Pool preventing the possibility of cracking your pool account (If you were on a traditional pool,) and stealing all your coins.

How do I Find a Nearby P2Pool Node

You can find the public p2pool nodes the the P2Pool Node Scanners. If you want to find a network 1 node go here. If you want to find a network 2 node go here.

How do I setup a P2Pool Node?

Linux P2Pool Setup
Windows P2Pool Setup (Text)
Windows P2Pool Setup (Video) This guide setups a network 2 node. When downloading Python download the 32bit version, not the 64bit. Downloading the 64bit version causes problems with the twisted install.
How do I setup a change my node to network 1 or network 2?
In the P2Pool startup script when you type the --network flag add vertcoin1 for network 1 and vertcoin2 for network 2 right after.

How do I Buy Vertcoin?

You can see a video guide on Youtube, "How to Buy Vertcoin with Fiat Using Bittrex and Coinbase"

How can I get help with "X problem?"

The quickest way for you to get help is for you to join the Vertcoin Discord Group. We almost always have knowledgable Vertans, whether that be developers or experienced Vertans, online to help you with whatever problems you may have.

How can I donate to the Developers?

You can donate to the dev fund at https://vertcoin.org/donate/. You can select what you want your funds to go to by donating to the corresponding address. You can also see how much funding is required and how much we have donated.

Where can I see what exchanges Vertcoin is on?

You can see what exchanges Vertcoin is listed on at CoinMarketCap. You can see what exchanges Vertcoin has applied to be on at this google docs spreadsheet.

Where can I see Vertcoin's Roadmap?

The Vertcoin developers currently have a trello board where you can see the goals and what the status of said goal is. You can also vote on what you want the Vertcoin developers to focus on next.

What is the Status of the AMD Optimized Miner?

The AMD Optimized Miner internal beta is aiming to be ready by the end of September. The AMD Optimized Miner is currently being developed by @turekaj on the Vertcoin Discord. He currently does not have a Reddit account and Discord is the only way you can contact him.

What Does Halving Mean?

Halving means that the block reward for miners will be split in half. Halving happens around every 4 years for Vertcoin or 840,000 blocks. This means around December miners will only receive 25 VTC per block instead of the current 50 VTC per block.
If you would like to add another question to this list please comment it and I will get around to adding it ASAP.

2 Reasons Why Dogecoin Should Adapt Vertcoin's Features

Dogecoin should adapt both Scrypt-n as it's proof of work, and Kimotos Gravity Well as the method for adjusting difficulty.
Let me start with Kimitos Gravity Well. This is an algorithm used for adjusting the network difficulty. It adjusts the difficulty slightly every block rather than every set period, so that profit switching pools can not take advantage of it. It smooths out difficulty adjustments too.
This is needed because Dogecoin is about to be exploited by profit switching pools. Right now there's about 50 GH/s(over half of the network!) of profit switching pools mining Doge. When the block reward is halved in less than a week, we're going to see a ton of coin hopping between Litecoin and Dogecoin by these pools. This threatens the network, as the hashrate distribution and difficulty would become incredibly unstable. With this change, the difficulty would only fluctuate by about 5-10% throughout the day even with profit switching pools, unlike the 50%+ it will likely see using the current method.
The second thing is adaptive scrypt-n. Scrypt-n is a proof of work algorithm that makes ASICs nearly impossible to create. It adjusts the memory requirement on a block schedule, so that ASICs would likely never be made for it. ASICs are dedicated devices for mining that are much more power efficient than GPUs, and eventually will become more cost efficient. Dogecoin uses plain scrypt, and ASICs for it are already being developed. Eventually once these devices become more advanced, they will make gpu mining near impossible, and you will need an ASIC to profit or even make a moderate amount of Doge.
ASICs will make acquiring Dogecoin hard for newcomers. Looking at Bitcoin, many ASIC companies like BFL end up as scams, and those that aren't charge ridiculous prices for units that won't even make ROI. Mining with a gpu will get you nothing. I don't want this to happen to Dogecoin, as it is a fun cryptocurrency that is designed for the people. Eventually ASIC companies may withhold their technologies and use it for themselves, and as a result could control too much of the network. Look at Bitcoin, where KNC miner plans to create a 10 Megawatt mining farm in Sweden that is estimated to control 60-70% of the network.
Not just do ASICs ruin the fun of the coin by making it impossible for newcomers to easily mine a few doge, but it also ruins the security of the coin long term. I really hope we can convince the devs to implement scrypt-n, as I want Dogecoin to stay fun and secure. It sadly would require a hard fork, but it would be planned ahead of time. Better now than before Dogecoin grows larger, and before people with thousands of dollars invested into ASICs refuse to switch. Don't wait until ASICs become overpowered-it will be too late.
Vertcoin is a great coin from a technical standpoint, but it lacks the large and friendly community Dogecoin has behind it and also is deflationary, making it not as ideal as an internet currency that is intended to be shared a lot. I feel like Dogecoin could make great use of it's technology.

So you’ve got your miner working, busy hashing away … but what is it really doing?

Posted for eternity @ https://vertcoin.easymine.online/articles/mining
Your miner is repeatedly hashing (see below for detail about a hash) a block of data, looking for a resulting output that is lower than a predetermined target. Each time this calculation is performed, one of the fields in the input data is changed, and this results in a different output. The output is not able to be determined until the work is completed – otherwise why would we bother doing the work in the first place?
Each hash takes a block header (see more below, but basically this is a 80-byte block of data). It runs this through the hashing function, and what comes out is a 32-byte output. For each, we usually represent that output in hexadecimal format, so it looks something like:
5da4bcb997a90bec188542365365d8b913af3f1eb7deaf55038cfcd04f0b11a0 
(that’s 64 hexadecimal characters – each character represents 4-bits. 64 x 4 bits = 256bit = 32 bytes)
The maximum value for our hash is:
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF 
And the lowest is:
0000000000000000000000000000000000000000000000000000000000000000 
The goal in Proof-of-Work systems is to look for a hash that is lower than a specific target, i.e. starts with a specific number of leading zeros. This target is what determines the difficulty.
As the output of the hash is indeterminate, we look to statistics and probability to estimate how much work (i.e. attempts at hashing) we need to complete to find a hash that is lower than a specific target. So, we can therefore assume that to find a hash that starts with a leading zero will take, on average, 16 hashes. To find one that will start with two leading zeros (00), we’re looking at 256 hashes. Four leading zeros (0000) will take 65,536 hashes. Eight leading zeros (00000000) takes 4,294,967,296 hashes. So on and so on, until we realize that it will take 2 ^ 256 (a number too big for me to show here) attempts at hitting our minimum hash value.
Remember – this number of hashes is just an estimate. Think of it like rolling a dice. A 16-sided dice. And then rolling it 64 times in a row. And hoping to strike a specific number of leading zeros. Sometimes it will take far less than the estimate, sometimes it will take far more. Over a long enough time period though (with our dice it may take many billions of years), the averages hold true.
Difficulty is a measure used in cryptocurrencies to simply show how much work is needed to find a specific block. A block of difficulty 1 must have a hash smaller than:
00000000FFFF0000000000000000000000000000000000000000000000000000 
A block of difficulty 1/256 (0.00390625) must have a hash lower than:
000000FFFF000000000000000000000000000000000000000000000000000000 
And a block of difficulty 256 must have a hash lower than:
0000000000FFFF00000000000000000000000000000000000000000000000000 
So the higher the difficulty, the lower the hash must be; therefore more work must be completed to find the block.
Take a recent Vertcoin block – block # 852545, difficulty 41878.60056944499. This required a hash lower than:
000000000001909c000000000000000000000000000000000000000000000000 
The achieve finding this, a single miner would need to have completed, on average 179,867,219,848,013 hashes (calculated by taking the number of hashes needed for a difficulty 1 block - 4,294,967,296 or 2 ^ 32 or 16 ^ 8 – and multiplied by the difficulty). Of course, our single miner may have found this sooner – or later – than predicted.
Cryptocurrencies alter the required difficulty on a regular basis (some like Vertcoin do it after every block, others like Bitcoin or Litecoin do it every 2016 blocks), to ensure the correct number of blocks are found per day. As the hash rate of miners increases, so does the difficulty to ensure this average time between blocks remains the same. Likewise, as hash rate decreases, the difficulty decreases.
With difficulties as high as the above example, solo-mining (mining by yourself, not in a pool) becomes a very difficult task. Assume our miner can produce 100 MH/s. Plugging in this into the numbers above, we can see it’s going to take him (on average) 1,798,673 seconds of hashing to find a hash lower than the target – that’s just short of 21 days. But, if his luck is down, it could easily take twice that long. Or, if he’s lucky, half that time.
So, assuming he hit’s the average, for his 21 days mining he has earned 25 VTC.
Lets take another look at the same miner, but this time he’s going to join a pool, where he is working with a stack of other miners looking for that elusive hash. Assume the pool he has joined does 50 GH/s – in that case he has 0.1 / 50 or 0.2% of the pool’s hash rate. So for any blocks the pool finds he should earn 0.2% of 25 VTC = 0.05 VTC. At 50 GH/s, the pool should expect to spend 3,597 seconds between finding blocks (2 ^ 32 * difficulty / hashrate). So about every hour, our miner can expect to earn 0.05 VTC. This works out to be about 1.2 VTC per day, and when we extrapolate over the estimated 21 days of solo mining above, we’re back to 25 VTC.
The beauty of pooled-mining over solo-mining is that the time between blocks, whilst they can vary, should be closer to the predicted / estimated times over a shorter time period. The same applies when comparing pools – pools with a smaller hash rate will experience a greater variance in time between blocks than a pool with a greater hash rate. But in the end, looking back over a longer period of time, earnings will be the same.
Hashes
A Hash is a cryptographic function that can take an arbitrary sized block of data and maps it to a fixed sized output. It is a one-way function – only knowing the input data can one calculate the output; the reverse action is impossible. Also, small changes to the input data usually result in significant changes to the output value.
For example, take the following string:
“the quick brown fox jumps over the lazy dog” 
If we perform a SHA256 hash of this, it results in:
05c6e08f1d9fdafa03147fcb8f82f124c76d2f70e3d989dc8aadb5e7d7450bec 
If we change a single character in the input string (in this case we will replace the ‘o’ in ‘over’ to a zero), the resulting hash becomes:
de492f861d6bb8438f65b2beb2e98ae96a8519f19c24042b171d02ff4dfecc82 
Blocks
A block is made up of a header, and at least one transaction. The first transaction in the block is called the Coinbase transaction – it is the transactions that creates new coins, and it specifies the addresses that those coins go to. The Coinbase transaction is always the first transaction in a block, and there can only be one. All other transactions included in a block are transactions that send coins from one wallet address to another.
The block header is an 80-byte block of data that is made up of the following information in this order:
  • Version – a 32-bit/4-byte integer
  • Previous Block’s SHA256d Hash – 32 bytes
  • Merkle Hash of the Transactions – 32 bytes
  • Timestamp - a 32-bit/4-byte integer the represents the time of the block in seconds past 1st January 1970 00:00 UTC
  • nBits - a 32-bit/4-byte integer that represents the maximum value of the hash of the block
  • Nonce - a 32-bit/4-byte integer
The Version of a block remains relatively static through a coin’s lifetime – most blocks will have the same version. Typically only used to introduce new features or enforce new rules – for instance Segwit adoption is enforced by encoding information into the Version field.
The Previous Blocks’ Hash is simple a doubled SHA256 hash of the last valid blocks header.
The Merkle Hash is a hash generated by chaining all of the transactions together in a hash tree – thus ensuring that once a transaction is included in a block, it cannot be changed. It becomes a permanent record in the blockchain.
Timestamp loosely represents the time the block was generated – it does not have to be exact, anywhere within an hour each way of the real time will be accepted.
nBits – this is the maximum hash that this block must have in order to be considered valid. Bitcoin encodes the maximum hash into a 4-byte value as this is more efficient and provides sufficient accuracy.
Nonce – a simple 4-byte integer value that is incremented by a miner in order to find a resulting hash that is lower than that specified by nBits.

IRC Log from Ravencoin Open Developer Meeting - Aug 24, 2018

[14:05] <@wolfsokta> Hello Everybody, sorry we're a bit late getting started
[14:05] == block_338778 [[email protected]/web/freenode/ip.72.214.222.226] has joined #ravencoin-dev
[14:06] <@wolfsokta> Here are the topics we would like to cover today • 2.0.4 Need to upgrade - What we have done to communicate to the community • Unique Assets • iOS Wallet • General Q&A
[14:06] == Chatturga changed the topic of #ravencoin-dev to: 2.0.4 Need to upgrade - What we have done to communicate to the community • Unique Assets • iOS Wallet • General Q&A
[14:06] <@wolfsokta> Daben, could you mention what we have done to communicate the need for the 2.0.4 upgrade?

[14:08] Whats up bois
[14:08] hi everyone
[14:08] hi hi
[14:08] <@wolfsokta> Discussing the 2.0.4 update and the need to upgrade.
[14:08] <@Chatturga> Sure. As most of you are aware, the community has been expressing concerns with the difficulty oscillations, and were asking that something be done to the difficulty retargeting. Many people submitted suggestions, and the devs decided to implement DGW.
[14:09] <@Tron> I wrote up a short description of why we're moving to a new difficulty adjustment. https://medium.com/@tronblack/ravencoin-dark-gravity-wave-1da0a71657f7
[14:09] <@Chatturga> I have made posts on discord, telegram, bitcointalk, reddit, and ravencointalk.org from testnet stages through current.
[14:10] <@Chatturga> If there are any other channels that can reach a large number of community members, I would love to have more.
[14:10] <@wolfsokta> Thanks Tron, that hasn't been shared to the community at large yet, but folks feel free to share it.
[14:10] When was this decision made and by whom and how?
[14:10] <@Chatturga> I have also communicated with the pool operators and exchanges about the update. Of all of the current pools, only 2 have not yet updated versions.
[14:11] <@wolfsokta> The decision was made by the developers through ongoing requests for weeks made by the community.
[14:12] <@wolfsokta> Evidence was provided by the community of the damages that could be caused to projects when the wild swings continue.
[14:12] So was there a meeting or vote? How can people get invited
[14:12] <@Tron> It was also informed by my conversations with some miners that recommended that we make the change before the coin died. They witnessed similar oscillations from which other coins never recovered.
[14:13] only two pools left to upgrade is good, what about the exchanges? Any word on how many of those have/have not upgraded?
[14:13] <@wolfsokta> We talked about here in our last meeting Bruce_. All attendees were asked if they had any questions or concerns.

[14:14] <@Chatturga> Bittrex, Cryptopia, and IDCM have all either updated or have announced their intent to update.

[14:15] sup russki
[14:15] what's the status here?
[14:15] I don’t think that was at all clear from the last dev meeting
[14:15] I can’t be the only person who didn’t understand it
[14:15] <@wolfsokta> Are there any suggestions on how to communicate the need to upgrade even further? I am concerned that others might also not understand.
[14:17] I’m not sold on the benefit and don’t understand the need for a hard fork — I think it’s a bad precedent to simply go rally exchanges to support a hard fork with little to no discussion
[14:17] so just to note, the exchanges not listed as being upgraded or have announced their intention to upgrade include: qbtc, upbit, and cryptobridge (all with over $40k usd volume past 24 hours according to coinmarketcap)
[14:18] <@wolfsokta> I don't agree that there was little or no discussion at all.
[14:19] <@wolfsokta> Looking back at our meeting notes from two weeks ago "fork" was specifically asked about by BrianMCT.
[14:19] If individual devs have the power to simple decide to do something as drastic as a hard fork and can get exchanges and miners to do it that’s got a lot of issues with centralization
[14:19] <@wolfsokta> It had been implemented on testnet by then and discussed in the community for several weeks before that.
[14:19] == under [[email protected]/web/freenode/ip.72.200.168.56] has joined #ravencoin-dev
[14:19] howdy
[14:19] Everything I’ve seen has been related to the asset layer
[14:19] I have to agree with Bruce_, though I wasn't able to join the last meeting here. That said I support the fork
[14:20] Which devs made this decision to do a fork and how was it communicated?
[14:20] well mostly the community made the decision
[14:20] Consensus on a change is the heart of bitcoin development and I believe the devs have done a great job building that consensus
[14:20] a lot of miners were in uproar about the situation
[14:20] <@wolfsokta> All of the devs were supporting the changes. It wasn't done in isolation at all.
[14:21] This topic has been a huge discussion point within the RVN mining community for quite some time
[14:21] the community and miners have been having issues with the way diff is adjusted for quite some time now
[14:21] Sure I’m well aware of that -
[14:21] Not sold on the benefits of having difficulty crippled by rented hashpower?
[14:21] The community saw a problem. The devs got together and talked about a solution and implemented a solution
[14:21] I’m active in the community
[14:22] So well aware of the discussions on DGW etc
[14:22] Hard fork as a solution to a problem community had with rented hashpower (nicehash!!) sounds like the perfect decentralized scenario!
[14:23] hard forks are very dangerous
[14:23] mining parties in difficulty drops are too
[14:23] <@wolfsokta> Agreed, we want to keep them to an absolute minimum.
[14:23] But miners motivation it’s the main vote
[14:24] What would it take to convince you that constantly going from 4 Th/s to 500 Gh/s every week is worse for the long term health of the coin than the risk of a hard fork to fix it?
[14:24] == Tron [[email protected]/web/freenode/ip.173.241.144.77] has quit [Ping timeout: 252 seconds]
[14:24] This hardfork does include the asset layer right? if so why is it being delayed in implementation?
[14:24] <@wolfsokta> Come back Tron!
[14:24] coudl it have been implement through bip9 voting?
[14:24] also hard fork is activated by the community! that's a vote thing!
[14:24] @mrsushi to give people time to upgrade their wallet
[14:25] @under, it would be much hard to keep consensus with a bip9 change
[14:25] <@wolfsokta> We investigated that closely Under.
[14:25] == Tron [[email protected]/web/freenode/ip.173.241.144.77] has joined #ravencoin-dev
[14:25] <@wolfsokta> See Tron's post for more details about that.
[14:25] <@spyder_> Hi Tron
[14:25] <@wolfsokta> https://medium.com/@tronblack/ravencoin-dark-gravity-wave-1da0a71657f7
[14:25] Sorry about that. Computer went to sleep.
[14:26] I'm wrong
[14:26] 2 cents. the release deadline of october 31st puts a bit of strain on getting code shipped. (duh). but fixing daa was important to the current health of the coin, and was widely suppported by current mining majority commuity. could it have been implemented in a different manner? yes . if we didnt have deadlines
[14:27] == wjcgiwgu283ik3cj [[email protected]/web/freenode/ip.172.58.37.35] has quit [Quit: Page closed]
[14:27] sushi this fork does not include assets. it's not being delayed though, we're making great progress for an Oct 31 target
[14:28] I don’t see the urgency but my vote doesn’t matter since my hash power is still CPUs
[14:28] <@wolfsokta> We're seeing the community get behind the change as well based on the amount of people jumping back in to mine through this last high difficulty phase.
[14:28] So that will be another hardfork?
[14:28] the fork does include the asset code though set to activate on oct 30th
[14:28] yes
[14:29] <@wolfsokta> Yes, it will based on the upgrade voting through the BIP9 process.
[14:29] I wanted to ask about burn rates from this group: and make a proposal.
[14:29] we're also trying hard to make it the last for awhile
[14:29] Can you clear up the above — there will be this one and another hard fork?
[14:29] <@wolfsokta> Okay, we could discuss that under towards the end of the meeting.
[14:30] If this one has the asset layer is there something different set for October
[14:30] <@wolfsokta> Yes, there will be another hard fork on October 31st once the voting process is successful.
[14:31] <@wolfsokta> The code is in 2.0.4 now and assets are active on testnet
[14:31] Bruce, the assets layer is still being worked on. Assets is active on mainnet. So in Oct 31 voting will start. and if it passes, the chain will fork.
[14:31] this one does NOT include assets for mainnet Bruce -- assets are targeted for Oct 31
[14:31] not***
[14:31] not active****
[14:31] correct me if I'm wrong here, but if everyone upgrades to 2.0.4 for this fork this week, the vote will automatically pass on oct 31st correct? nothing else needs to be done
[14:31] Will if need another download or does this software download cover both forks?
[14:31] <@wolfsokta> Correct Urgo
[14:32] thats how the testnet got activated and this one shows "asset activation status: waiting until 10/30/2018 20:00 (ET)"
[14:32] Will require another upgrade before Oct 31
[14:32] thank you for the clarification wolfsokta
[14:32] <@wolfsokta> It covers both forks, but we might have additional bug fixes in later releases.
[14:32] So users DL one version now and another one around October 30 which activates after that basically?
[14:33] I understand that, but I just wanted to make it clear that if people upgrade to this version for this fork and then don't do anything, they are also voting for the fork on oct 31st
[14:33] Oh okay — one DL?
[14:33] Bruce, Yes.
[14:33] Ty
[14:33] well there is the issue that there maybe some further consensus bugs dealing with the pruneability of asset transactions that needs to be corrected between 2.0.4 and mainnet. so i would imagine that there will be further revisions required to upgrade before now and october 31
[14:33] @under that is correct.
[14:34] I would highly recommend bumping the semver up to 3.0.0 for the final pre 31st release so that the public know to definitely upgrade
[14:34] @under +1
[14:35] out of curiosity, have there been many bugs found with the assets from the version released in july for testnet (2.0.3) until this version? or is it solely a change to DGW?
[14:35] <@wolfsokta> That's not a bad idea under.
[14:35] <@spyder_> @under good idea
[14:35] @urgo. Bugs are being found and fixed daily.
[14:35] Any time the protocol needs to change, there would need to be a hard fork (aka upgrade). It is our hope that we can activate feature forks through the BIP process (as we are doing for assets). Mining pools and exchanges will need to be on the newest software at the point of asset activation - should the mining hash power vote for assets.
[14:35] blondfrogs: gotcha
[14:35] There have been bugs found (and fixed). Testing continues. We appreciate all the bug reports you can give us.
[14:36] <@wolfsokta> Yes! Thank you all for your help in the community.
[14:37] (pull requests with fixes and test coverage would be even better!)
[14:37] asset creation collision is another major issue. current unfair advantage or nodes that fore connect to mining pools will have network topologies that guarantee acceptance. I had discussed the possibility of fee based asset creation selection and i feel that would be a more equal playing ground for all users
[14:38] *of nodes that force
[14:38] <@wolfsokta> What cfox said, we will always welcome development help.
[14:38] So just to make sure everyone know. When assets is ready to go live on oct 31st. Everyone that wants to be on the assets chain without any problems will have to download the new binary.
[14:39] <@wolfsokta> The latest binary.
[14:39] under: already in the works
[14:39] excellent to hear
[14:39] == UserJonPizza [[email protected]/web/freenode/ip.24.218.60.237] has joined #ravencoin-dev
[14:39] <@wolfsokta> Okay, we've spent a bunch of time on that topic and I think it was needed. Does anybody have any other suggestions on how to get the word out even more?
[14:40] maybe preface all 2.0.X releases as pre-releases... minimize the number of releases between now and 3.0 etc
[14:41] <@wolfsokta> Bruce_ let's discuss further offline.
[14:41] wolfsokta: which are the remaining two pools that need to be upgraded? I've identified qbtc, upbit, and cryptobridge as high volume exchanges that haven't said they were going to do it yet
[14:41] so people can help reach out to them
[14:41] f2pool is notoriously hard to contact
[14:41] are they on board?
[14:42] <@wolfsokta> We could use help reaching out to QBTC and Graviex
[14:42] I can try to contact CB if you want?
[14:42] <@Chatturga> The remaining pools are Ravenminer and PickAxePro.
[14:42] <@Chatturga> I have spoken with their operators, the update just hasnt been applied yet.
[14:42] ravenminer is one of the largest ones too. If they don't upgrade that will be a problem
[14:42] okay good news
[14:42] (PickAxePro sounds like a Ruby book)
[14:43] I strongly feel like getting the word out on ravencoin.org would be beneficial
[14:44] that site is sorely in need of active contribution
[14:44] Anyone can volunteer to contribute
[14:44] <@wolfsokta> Okay, cfox can you talk about the status of unique assets?
[14:44] sure
[14:45] <@wolfsokta> I'll add website to the end of our topics.
[14:45] code is in review and will be on the development branch shortly
[14:45] would it make sense to have a page on the wiki (or somewhere else) that lists the wallet versions run by pools & exchanges?
[14:45] will be in next release
[14:45] furthermore, many sites have friendly link to the standard installers for each platform, if the site linked to the primary installers for each platform to reduce github newb confusion that would be good as well
[14:46] likely to a testnetv5 although that isn't settled
[14:46] <@wolfsokta> Thanks cfox.
[14:46] <@wolfsokta> Are there any questions about unique assets, and how they work?
[14:47] after the # are there any charachters you cant use?
[14:47] will unique assets be constrained by the asset alphanumeric set?
[14:47] ^
[14:47] <@Chatturga> @Urgo there is a page that tracks and shows if they have updated, but it currently doesnt show the actual version that they are on.
[14:47] a-z A-Z 0-9
[14:47] <@Chatturga> https://raven.wiki/wiki/Exchange_notifications#Pools
[14:47] There are a few. Mostly ones that mess with command-line
[14:47] you'll be able to use rpc to do "issueunique MATRIX ['Neo','Tank','Tank Brother']" and it will create three assets for you (MATRIX#Neo, etc.)
[14:47] @cfox - No space
[14:48] @under the unique tags have an expanded set of characters allowed
[14:48] Chatturga: thank you
[14:48] @UJP yes there are some you can't use -- I'll try to post gimmie a sec..
[14:49] Ok. Thank you much!
[14:49] 36^36 assets possible and 62^62 uniques available per asset?
[14:49] <@spyder_> std::regex UNIQUE_TAG_CHARACTERS("^[[email protected]$%&*()[\\]{}<>_.;?\\\\:]+$");
[14:50] regex UNIQUE_TAG_CHARACTERS("^[[email protected]$%&*()[\\]{}<>_.;?\\\\:]+$")
[14:50] oh thanks Mark
[14:51] <@wolfsokta> Okay, next up. I want to thank everybody for helping test the iOS wallet release.
[14:51] <@wolfsokta> We are working with Apple to get the final approval to post it to the App Store
[14:51] @under max asset length is 30, including unique tag
[14:51] Does the RVN wallet have any other cryptos or just RVN?
[14:52] == BruceFenton [[email protected]/web/freenode/ip.67.189.233.170] has joined #ravencoin-dev
[14:52] will the android and ios source be migrated to the ravenproject github?
[14:52] I've been adding beta test users. I've added about 80 new users in the last few days.
[14:52] <@wolfsokta> Just RVN, and we want to focus on adding the asset support to the wallet.
[14:53] == Bruce_ [[email protected]/web/freenode/ip.67.189.233.170] has quit [Ping timeout: 252 seconds]
[14:53] <@wolfsokta> Yes, the code will also be freely available on GitHub for both iOS and Android. Thank you Roshii!
[14:53] Would you consider the iOS wallet to be a more secure place for one's holdings than say, a Mac connected to the internet?
[14:53] will there be a chance of a more user freindly wallet with better graphics like the iOS on PC?
[14:53] the android wallet is getting updated for DGW, correct?
[14:53] <@wolfsokta> That has come up in our discussion Pizza.
[14:54] QT framework is pretty well baked in and is cross platform. if we get some qt gurus possibly
[14:54] Phones are pretty good because the wallet we forked uses the TPM from modern phones.
[14:54] Most important is to write down and safely store your 12 word seed.
[14:54] TPM?
[14:54] <@wolfsokta> A user friendly wallet is one of our main goals.
[14:55] TPM == Trusted Platform Module
[14:55] Ahhh thanks
[14:55] just please no electron apps. they are full of security holes
[14:55] <@spyder_> It is whats makes your stuffs secure
[14:55] not fit for crypto
[14:55] under: depends on who makes it
[14:55] The interface screenshots I've seen look like Bread/Loaf wallet ... I assume that's what was forked from
[14:55] ;)
[14:56] <@wolfsokta> @roshii did you see the question about the Android wallet and DGW?
[14:56] Yes, it was a fork of breadwallet. We like their security.
[14:56] chromium 58 is the last bundled electron engine and has every vuln documented online by google. so unless you patch every vuln.... methinks not
[14:56] Agreed, great choice
[14:57] <@wolfsokta> @Under, what was your proposal?
[14:58] All asset creation Transactions have a mandatory OP_CHECKLOCKTIMEVERIFY of 1 year(or some agreed upon time interval), and the 500 RVN goes to a multisig devfund, run by a custodial group. We get: 1) an artificial temporary burn, 2) sustainable community and core development funding for the long term, after OSTK/Medici 3) and the reintroduction of RVN supply at a fixed schedule, enabling the removal of the 42k max cap of total As
[14:58] *im wrong on the 42k figure
[14:58] <@wolfsokta> Interesting...
[14:59] <@wolfsokta> Love to hear others thoughts.
[14:59] Update: I posted a message on the CryptoBridge discord and one of their support members @stepollo#6276 said he believes the coin team is already aware of the fork but he would forward the message about the fork over to them right now anyway
[14:59] Ifs 42 million assets
[14:59] yep.
[15:00] I have a different Idea. If the 500 RVN goes to a dev fund its more centralized. The 500 RVN should go back into the unmined coins so miners can stay for longer.
[15:01] *without a hardfork
[15:01] <@wolfsokta> lol
[15:01] that breaks halving schedule, since utxos cant return to an unmined state.
[15:01] @UJP back into coinbase is interesting. would have to think about how that effects distribution schedule, etc.
[15:01] only way to do that would be to dynamicaly grow max supply
[15:02] and i am concerned already about the max safe integer on various platforms at 21 billion
[15:02] js chokes on ravencoin already
[15:02] <@wolfsokta> Other thoughts on Under's proposal? JS isn't a real language. ;)
[15:02] Well Bitcoin has more than 21 bn Sats
[15:02] Is there somebody who wants to volunteer to fix js.
[15:02] hahaha
[15:03] I honestly would hate for the coins to go to a dev fund. It doesn't seem like Ravencoin to me.
[15:03] Yep, but we're 21 billion x 100,000,000 -- Fits fine in a 64-bit integer, but problematic for some languages.
[15:03] <@wolfsokta> Thanks UJP
[15:04] <@wolfsokta> We're past time but I would like to continue if you folks are up for it.
[15:04] Yeah no coins can go anywhere centrality contorted like a dev fund cause that would mean someone has to run it and the code can’t decide that so it’s destined to break
[15:05] currently and long term with out the financial backing of development then improvements and features will be difficult. we are certainly thankful for our current development model. but if a skunkworks project hits a particular baseline of profitability any reasonable company would terminate it
[15:05] Yes let’s contibue for sure
[15:05] the alternative to a dev fund in my mind would be timelocking those funds back to the issuers change address
[15:06] But we can’t have dev built in to the code — it has to be open source like Bitcoin and monero and Litecoin - it’s got drawbacks but way more advantages- it’s the best model
[15:06] Dev funding
[15:06] i highly reccommend not reducing the utility of raven by removing permanently the supply
[15:07] == BW_ [[email protected]/web/freenode/ip.138.68.243.202] has joined #ravencoin-dev
[15:07] timelocking those funds accompllishes the same sacrifice
[15:07] @under timelocking is interesting too
[15:07] How exactly does timelocking work?
[15:07] <@wolfsokta> ^
[15:07] I mean you could change the price of assets with the Block reward halfing.
[15:07] == Roshiix [[email protected]/web/freenode/ip.105.67.2.212] has joined #ravencoin-dev
[15:08] funds cant be spent from an address until a certain time passes
[15:08] but in a what magical fairy land do people continue to work for free forever. funding development is a real issue... as much as some might philosphically disagree. its a reality
[15:08] You’d still need a centralized party to decide how to distribute the funds
[15:08] even unofficially blockstream supports bitcoin devs
[15:08] on chain is more transparent imho
[15:09] == Tron_ [[email protected]/web/freenode/ip.173.241.144.77] has joined #ravencoin-dev
[15:09] @UJP yes there are unlimited strategies. one factor that I think is v important is giving application developers a way to easily budget for projects which leads to flat fees
[15:09] If the project is a success like many of believe it will be, I believe plenty of people will gladly done to a dev fund. I don't think the 500 should be burned.
[15:09] *donate
[15:09] centralized conservatorship, directed by community voting process
[15:10] == Tron [[email protected]/web/freenode/ip.173.241.144.77] has quit [Ping timeout: 252 seconds]
[15:10] <@wolfsokta> Thanks Under, that's an interesting idea that we should continue to discuss in the community. You also mentioned the existing website.
[15:10] It would need to be something where everyone with a QT has a vote
[15:10] think his computer went to sleep again :-/
[15:10] I agree UJP
[15:10] with the website
[15:10] No that’s ico jargon — any development fund tied to code would have to be centralized and would therefor fail
[15:11] ^
[15:11] ^
[15:11] ^
[15:11] dashes model for funding seems to be pretty decentralized
[15:11] community voting etc
[15:11] Once you have a dev fund tied to code then who gets to run it? Who mediates disputes?
[15:11] oh well another discussion
[15:11] Dash has a CEO
[15:12] <@wolfsokta> Yeah, let's keep discussing in the community spaces.
[15:12] Dash does have a good model. It's in my top ten.
[15:12] having the burn go to a dev fund is absolute garbage
[15:12] These dev chats should be more target than broad general discussions — changing the entire nature of the coin and it’s economics is best discussed in the RIPs or other means
[15:13] <@wolfsokta> Yup, let's move on.
[15:13] just becuase existing implementation are garbage doesnt mean that all possible future governance options are garbage
[15:13] <@wolfsokta> To discussing the website scenario mentioned by under.
[15:13] the website needs work. would be best if it could be migrated to github as well.
[15:13] What about this: Anyone can issue a vote once the voting feature has been added, for a cost. The vote would be what the coins could be used for.
[15:14] features for the site that need work are more user friendly links to binaries
[15:14] <@wolfsokta> We investigated how bitcoin has their website in Github to make it easy for contributors to jump in.
[15:14] that means active maintenance of the site instead of its current static nature
[15:15] <@wolfsokta> I really like how it's static html, which makes it super simple to host/make changes.
[15:15] the static nature isn’t due to interface it’s due to no contributors
[15:15] no contribution mechanism has been offered
[15:15] github hosted would allow that
[15:16] We used to run the Bitcoin website from the foundation & the GitHub integration seemed to cause some issues
[15:16] its doesnt necessarily have to be hosted by github but the page source should be on github and contributions could easily be managed and tracked
[15:17] for example when a new release is dropped, the ability for the downlaods section to have platform specific easy links to the general installers is far better for general adoption than pointing users to github releases
[15:18] <@wolfsokta> How do people currently contribute to the existing website?
[15:18] they dont?
[15:18] We did that and it was a complete pain to host and keep working — if someone wants to volunteer to do that work hey can surely make the website better and continually updated — but they could do that in Wordpress also
[15:19] I’d say keep an eye out for volunteers and maybe we can get a group together who can improve the site

[15:20] I host the source for the explorer on github and anyone can spin it up instantly on a basic aws node. changes can be made to interface etc, and allow for multilingual translations which have been offered by some community members
[15:20] there are models that work. just saying it should be looked at

Most alt-coins are NOT secure enough, they exist only for entertainment and speculation

(I believe this needs to be posted to /bitcoin as Bitcoin users/enthusiasts need to know the difference between Bitcoin and other cryptocurrencies. About author: I'm subscribed to /bitcoin since 2011, and have been involved in cryptocurrency security research for several years.)
Let's talk about security aspect of cryptocurrencies. I'm afraid an average user knows very little about this topic: he might know that hashrate is needed to protect the blockchain, and that higher hashrate is better, as it implies that attacker needs to spend more to get control of the blockchain.
But there is a plenty of other kinds of attacks (or, rather, economic models of attacks), some of which have much higher practical significance.
Let's start with something simple: there is a straightforward and rigorous model of double-spending attack under condition that attacker has a fraction of total network's hashrate. I highly recommend Meni Rosenfeld's Analysis of hashrate-based double-spending paper (PDF).
The main takeaway from this paper is that "maximal safe transaction value" is directly proportional to block reward (i.e. amount of coins miners get for each block). It is easy to understand this intuitively: bigger reward means that miners get more money from normal mining, so they will be reluctant to try double-spending attacks. On the other hand, if block reward was negligible, double-spending could be a lucrative source of revenue.
Let's look at numbers: if attacker controls 26% of hashrate and number of confirmations is 6, maximal safe transaction value is 1113 BTC when block reward is 25 BTC. This is pretty cool: you only need to wait 1 hour to make sure you irreversibly received half million USD worth of bitcoins (I assume exchange rate of $450 for 1 Bitcoin).
However, situation is pretty different for alt-coins which have much less valuable block rewards. For example, imagine there is a Foocoin with exchange rate of $1 for 1 Foocoin. If Foocoin's block reward is also 25 foocoins, then max save transaction value for 6 confirmations is only $1113 USD worth of Foocoins. It doesn't look like Foocoin is suitable for commerce, does it?
One could say that Foocoin simply requires larger number of confirmations for larger transactions. But that's wrong: higher number of confirmations helps only under condition that attacker is unable to obtain more than 50% of total hashrate, but for most alt-coins it isn't true.
First of all, let's note that so-called miners simply rent their equipment to "mining pool operators" and are paid in crypto-currency for it. In many cases they don't even care what cryptocurrency they mine as long as they are being paid. See Middlecoin:
This pool automatically mines the most profitable scrypt coin, automatically exchanges those coins for bitcoins, and pays out entirely in bitcoins.
So, miners who mine using Middlecoin do not know if their equipment is being used to mine Litecoins or Dogecoins or something else. And they wouldn't care if it is used for attacks on alt-coins, as they are being paid in bitcoins.
Let's consider a scenario where Middlecoin-like pool has higher hashrate than Foocoin, e.g. Middlecoin (not Middlecoin specifically, but any pool like that) has 20 GH/s, while Foocoin has 10 GH/s. Here's how one can profit from it:
  1. Buy $1M worth of Foocoins, get them into your wallet.
  2. Make an agreement with Middlecoin: you rent they hashrate for a couple of hours, paying them in bitcoin, slightly above what most profitable alt-coin yields.
  3. Send your foocoins to exchange Bar.
  4. Start mining a private chain which has a double-spend transaction which sends coins to exchange Baz.
  5. After your transaction gets 10 confirmations on the normal chain, convert foocoins to bitcoins on Bar and withdraw them immediately.
  6. After withdrawal transaction is confirmed on Bitcoin network (and thus cannot be reversed), you release the private chain you have mined, causing reorganization. You should have mined 20 blocks by then under if Middlecoin has hashrate which is twice higher than normal Foocoin's hashrate.
  7. Your deposit to exchange Baz is now confirmed, converl your foocoins to bitcoins again, and withdraw immediately.
  8. A day later 20 blocks you have mined will get mature, and you'll be able to sell them too.
If Foocoin price doesn't change in process, you can get approximately $1M profit on this attack, as cost of renting a mining pool is approximately equal to value of mined blocks.
In practice, you'll lose some money due to lack of liquidity on exchanges, so profit will be less than $1M.
The conclusion we get from this analysis is that alt-coins which have only a small fraction of total hashrate for a certain mining algorithm are extremely non-secure. And they cannot grow big: as soon as exchanges will have enough liquidity, it will be possible to perform the attack I described, which will result in the price drop.
So almost all alt-coins are simply not suitable for any kind of "real economy" applications. They are doomed to have high volatility, shallow markets, low "max safe transaction value".
One can't deny the fact that it is possible to make money on alt-coins. But that's just gambling. And people who create new alt-coins are in same position as people who build casinos. It is a business, but it is the entertainment sector, not in 'real economy' or 'financial' sectors as some people are trying to pretend.
Bitcoin is one of few cryptocurrencies which are actually serious. It isn't perfect, but attacking Bitcoin is very hard, so transactions worth millions of dollars can be confirmed in matter of hours. Same cannot be said about alt-coins, and this situation won't change unless new cryptocurrency designs will be found.
If there is an alt-coin which is more-or-less secure, it is probably Litecoin. Its hashrate is a significant fraction of total scrypt hashrate, so attacking Litecoin is hard. Interestingly, at some point Dogecoin's hashrate was higher than Litecoin's but it dropped after block reward have dropped. So, again, block reward is important for security.
This has dire implications for alt-coins which have short block reward schedules. If all coins will be mined in two years, this mean that alt-coin will be dead in two years.
(It's worth noting that same problem might affect Bitcoin in future, like in 10 years or so.)
Now there is a question: Is there a way to make multiple currencies all of which will be secure?
Probably. There are several approaches:
  1. Merged mining: The idea is that Bitcoin's proof-of-work can be re-used to mine alt-chains. This makes attacks harder, but hashrate-based double-spending considerations are still applicable, so safety can't be guaranteed... They will be safe only if miners are benevolent.
  2. Side-chains: This needs more research, but it looks like high degree of security is possible as long as you don't care about SPV.
  3. Proof-of-stake and PoW/PoS hybrid: Needs more research, there is some hope. Note that Peercoin's PoS is pretty bad.
  4. Multiple cryptocurrencies in the same blockchain (e.g. colored coins, Mastercoin, Counterparty, Ethereum, Ripple, etc.) will all be equally secure, so I believe this is what we should do instead of spawning a shitload of alt-coins.

Wafflepool & 51% attack - Don't panic. Here's what to do.

Hello, fellow shibes. Today, it seems we have another pool nearing the 51% hashrate threshold, as Dogehouse did in the past. We've had a lot of newcomers since, so I'll try to explain again what is the issue here, if it poses a real threat to the Dogecoin network, and what can be done.
What is Wafflepool ?
Wafflepool is, as its name suggests, a cryptocurrency mining pool (where several miners collaborate to ensure constant coin payouts). More precisely, it's called a "multipool", which means it alternates between several coins (like Dogecoin or Litecoin), to mine the most profitable one.
As I write this, Dogecoin is the #6 most profitable coin to mine (according to this website) and thus is the current target of Wafflepool.
They currently have a hashrate of about 33 GH/s, while the total hashrate of the Dogecoin network is about 80 GH/s. This means Wafflepool holds 41% of the hashpower of Dogecoin, and is nearing the minimal threshold for what is called a "51% attack".
What is a "51% attack" ?
The "51% attack" is a potential vulnerability in most cryptocurrencies. In this scenario, an attacker (in our case, a pool finely coordinating its workers) which holds at least 51% of the total hashrate of a cryptocurrency can create several anomalies in the coin's functioning. They could, for instance, reverse some transactions or disrupt other miners - which means they could destabilize the coin's overall network, and make its value plummet.
Is this a real issue ?
Yes and no. If a "51% attack" is successfully done, it may or may not be the end of Dogecoin - price falling through the floor, trust in the coin gone by the window, and investors fleeing like hell. This happened to other cryptocurrencies in the past.
But most probably, this won't happen : firstly because Wafflepool has few reasons to initiate a 51% attack (yes, some Bitcoin users hate us, but they're probably a minority ; yes, they would probably make a quick cashgrab, but they'd probably be better mining Doge in the long run). Secondly, because Dogecoin won't suddenly explode when Wafflepool goes over 51% ; they have to be actively coordinating such an attack. Finally, even if that's what they want, we can (and will !) stop them.
What can we do ?
  1. If you have a potent computer, hit the mines ! Check this out, choose a pool, and start mining. You will earn dogecoins and help protect the network by increasing the overall hashpower.
  2. Don't panic ! Don't go screaming around that the end of Dogecoin is near ; you'll only make the investors and miners run, which in turn will weaken the coin.
  3. Do not spread FUD. This is a relatively new technology for most people, so newcomers are easily scared ; and since we need more blood for the Shibe god fresh recruits to keep the mining pools running, this will have a bad effect on the network.
  4. If you spent money into Doge, if you believe in the future of the coin, and if you didn't invest more than you can afford to lose, don't panic sell. The people which became rich with Bitcoin were sitting on their coins, no matter what was happening. Don't have blind faith, but also don't get manipulated into selling your coins. Remember : if you're selling cheap, someone's also buying cheap.
That's all for now. If you have any questions, suggestions, criticism, or just anything to say, don't hesitate to tell me ; I (or another friendly shibe, we are all a great family !) will do my best to answer you.

A long term outlook at the Dogecoin economy and currency (intro & pt 1 - mining power and a 51% attack) [meta]

Dogecoin is awesome. Dogecoin is too the moon!
But like any moon mission, it's worth asking the question what can go wrong on the way there. What stakeholders exist in the Dogecoin economy, what outcomes are possible in Dogecoin's journey, and how those outcomes could affect the behavior of the stakeholders.
This post is designed to encourage you to ask questions about every aspect of how Dogecoin functions. I do not intend this as investment advice in any sense of the word and have worked hard to avoid any discussion about what will happen to the price of dogecoin in the future.
In this post I will outline the stakeholders, outline the factors that affect the currency, and address the question of how Hashrate is related to miners decisions, and how it protects Dogecoin from a 51% attack
A few of the key facts I'll discuss:
Disclosure: I own a small amount of Dogecoin and Bitcoin (less than $100 in total at current market value) It's purely for entertainment and research purposes.
At the moment, I see the following people in the Dogecoin community:
  1. Long term investors (individuals holding Dogecoin either as a store of value or an investment opportunity)
  2. Short term investors (individuals holding Dogecoin as an investment opportunity)
  3. Professional Dogecoin miners (individuals choosing to mine Dogecoin rather than other Scrypt based coins, motivated by income)
  4. Community Dogecoin miners (individuals choosing to mine Dogecoin because they like Dogecoin, not motivated by income)
  5. Dogecoin buyers and sellers (individuals using dogecoin as a short term medium of exchange)
  6. Dogecoin community members (individuals holding Dogecoin for fun and/or using it for non-monetary compensation {irrelevant of market value}
  7. Dogecoin developers (Individuals who will decide what changes are made to the Dogecoin protocol {some of which may affect market behavior})
It's important to note that individuals in the community can be in more than one category (someone who holds dogecoin for short term investment can also buy and sell dogecoin on the market)
Variables which can affect the above stakeholders:
A. The average (and future) mining reward from a block of Dogecoin per kilohash hour. (How much can I make mining Dogecoin, what will Dogecoin inflation look like)
B. The total mining power (in GH) focused on Dogecoin vs other Scrypt coins (the more distributed miners, the safer the blockchain)
C. The price of Dogecoin/Market Cap (to determine if Dogecoin is worth mining)
D. The market perception about the future price of Dogecoin (to determine if Dogecoin is worth holding/spending and worth mining) {this is harder to quantify}
E. The Transaction volume of Dogecoin (to determine the community interest in the currency)
F. The reliability of Fiat to Dogecoin exchanges and Crypto to Dogecoin Exchanges (to facilitate an efficient/accurate market price for Dogecoin)
G. The speed of Dogecoin conversion into fiat (for instant transactions by merchants)
H. The development pipeline for new Dogecoin compatible mining hardware (how far off are ASICs for Scrypt)
As I see it, there's one major outcome that affects the entire community equally.
A 51% attack on Dogecoin would be of massive adverse value to everyone (except the individuals perpetrating the attack). If Dogecoin's blockchain was corrupted, It would cease to function as a useful medium of exchange and as a store of value. Miners would leave because the value would plummet from it not being trusted. Short term investors would dump their holdings as they started to lose value. Long term investors would do the same.
The currency would die.
How does one prevent a 51% attack? Have a large total mining hashrate in the hands of a diverse number of miners. If the cost of running a 51% attack is so high it's not worth the money, it won't happen.
This leads to a fundamental question: what keeps people mining Dogecoin?
Dogecoin miners are separated into two groups (as mentioned above), Professional miners who will go where they can make the most money, and amateur miners who will mine Dogecoin because they like the currency.
From a community health perspective, the professional miners are the main concern (with a few caveats). If professional miners leave, that affects trust in Dogecoin.
So what keeps them mining for us? There are two major Scrypt based cryptos out right now, Litecoin and Dogecoin, and the community, as of this writing, is essentially split 50/50 is split 55/45 in favor of Dogecoin.
What this reflects is that miners expect to make more money mining Dogecoin than litecoin. Since an efficient market exists for trading Litecoin into Bitcoin and Dogecoin into Bitcoin, it seems to this author that value should be assessed in terms of current actual value (that miners choose what coin to mine based on how much they can sell it for today)
Since two large scale profitable currencies exist (LTE and DOGE) miners are going to choose the more profitable up until the point where the two converge. This depends on three variables:
Difficulty, total hash rate, and average reward.
As of Jan 23, DOGE is a little over twice as profitable as LTC.
This is what has prompted the major switch of the past few days.
I need help modeling is how much total value comes from LTC and how much from DOGE (essentially, if I owned the entire mining pool and split my work equally, how much could I make from each currency?)
At some point, enough miners will leave LTC that it's difficulty will drop. Assuming LTC retains its value (in fiat), falling difficulty will make it more profitable. Eventually, its profitability will once again match that of Dogecoin, and miners will stop leaving LTC for DOGE.
The problem is that as miners leave, it is possible that the currency value will drop as well.
On Jan 20, LTC had a 115GH rate, Doge had 57GH. Doge was trading at .00003 LTC. On Jan 23, Doge had 95, LTC had 75, and Doge more than doubled in price to .0000675. (Litecoin has also dropped about $1 (~5%) in value in USD over the same period.)
This is likely why even though Dogecoin has more miners than LTC, Litecoin is still less profitable for Miners (at this precise moment). Dogecoin has increased in currency value more than it has decreased in mining value.
Thus, the fundamental question is what kind of change is required in the price of DOGE/LTC and what hashing ratio will LTC and DOGE settle on based on their current price. It's important to remember that LTC has not dropped in value significantly, Doge has simply rose dramatically.
Fundamentally, as long as LTC has some value, it will have some percentage of Scrypt hashing power devoted to it. The same is true for Doge. So as long as people still want both currencies to some degree, mining power will be split. *Depending on that split, Dogecoin will be safe if it has enough mining power to prevent a malicious third party, and if that mining power remains in the hands of a diverse group of DOGE mining pools. *
My next post will address the different needs of the Long term investor, the short term investor, and the casual owner. (Some want a long term stable currency, some want a dramatic increase in price (even if it hurts the currency long term)
Please feel free to leave comments about anything you disagree with, any changes I should make, any thoughts about other factors that could affect the health of the currency, any other subjects you'd like to see explored. Thanks!

Where is the network difficulty headed, come November?

Reposted for accuracy. (Read: My math skills are the result of public education.)
KNCMiner announced today that they're doing encapsulation on their new Scrypt ASIC chips, and then when they're completed, will be shipping to Stockholm for integration and testing, buildout and finally...shipping!
I have read on forums that they have sold 3,000 Titans via pre-order, for batch 1, at 250MH/s nominal performance, each. I figured it was time to look at my "hashrate/difficulty prediction" again and see where it may actually be, by the time the snow's falling. All of the below is calculated with a Litecoin price of around $5.
Let's assume for a moment that both Alpha Technology and Mining ASICs Technologies have also sold around 3,000 systems on pre-order (probably a safe bet) and all three expect to ship in September-October.
9,000 systems @ 250MH/s = 2,250,000MH/s. That's somewhere in the neighborhood of 2.25 TH/s being added to the network in roughly two months' time...that we can account for.
The current network hashrate, as I post this? Not quite 1 TH/s...it's 896 GH/s. But at the current rate of network expansion, we're going to be 1 TH/s by the time these systems ship, easily.
So...let's say we're looking at a 3.5 TH/s Litecoin network by November. What does that mean?
When the Bitcoin network hit 3.5 TH/s back in May of 2011, the difficulty was around 244,000. Litecoin's difficulty is currently around 28,000.
You can probably see where this is going, already. Fun with mining calculators time.
Say you have one 250MH/s miner and deployed it TODAY (impossible, but for the sake of argument). You're looking at pulling in 9 LTC/day with it. If you pay $.10/kwh you're very lucky not to live in California, but we'll say that's the case. You pay around $4.50/day in power. So you walk away with $42.50 worth of Litecoin, at $5/each. If you somehow managed to freeze the network at that difficulty and the coin at that price, you'd pay off your $9,200 purchase of hardware in roughly seven months or so...or if you bought a Titan at $10,000 you're looking closer to eight. But since difficulty marches on, forget that entire concept.
Now...say you get your system after all three companies have shipped and their customers have deployed them, and we've seen the network rocked to the tune of two-and-a-quarter terahashes per second. Oh, it's a rosy picture...
Now, with the network difficulty having blown up to 244,000 the miner with a 250MH/s system is mining 1.03 Litecoin per day. And if my estimates are correct...this is NOVEMBER, we're talking about. At the current price of $5/LTC and $.10/kwh you are pulling down a healthy $0.80/day in profits, after power. If you again had the power to freeze the hashrate and price, you'd be able to pay off that hardware purchase in, oh...roughly 35 years.
To have a REASONABLE shot at getting a return on your investment (around 5-6 months), Litecoin will need to be $70 by November and climbing steadily, in concert with network hashrate.
Bear in mind, again that there is nowhere else for that hashrate to go but Litecoin. Nothing else will profit the Scrypt miner. So what will happen? There is built-in hardware cost here that has to be recouped and the only real way of doing that is by mining...and there's only one game in town for Scrypt mining: Litecoin.
It's going to be a really, really wild fourth quarter for this year. Either the miners mine and hoard, decreasing supply and demand increases radically, or miners take heavy losses on hardware, can't afford to run them and the Litecoin network contracts until they CAN make money with them. In the interests of self-preservation, I have a feeling miners will start hoarding. Soon.

intro to bitcoin and other cryptos (need help in designing class)

I have become the defacto "Bitcoin expert" in my little down of 50,000 people because I'm the only one talking about it (not because I'm an expert by any means). They have asked me to teach an intro class on bitcoin and other cryptocurrencies. I'm charging $5 for the class and giving them $5 back in a crypto currency (was going to be BTC until I saw the transaction times and fees we're dealing with right now). I figured I'd give the people in the front row $25, they pass back $20, they pass back $15, etc until everyone has $5 left. A quick lesson on how to transact using your phone or laptop.
The class will be two hours long plus an hour Q&A session at the end so I'm trying to cover the basics and a few intermediate ideas so should they come across them (like segwit, etc) they at least have a passing knowledge. I will NOT give any investment advice and I will not get complicated/technical.
I've been working on this syllabus for the last two days and would appreciate some feedback... am I missing something? could I explain things better? anything constructive is welcome. I'm sure some of my explanations are incorrect especially with regard to segwit, transactions, etc... any help is appreciated. Each class is 20 people and it's looking like there will be 4-6 classes based on current demand.
syllabus:
a) What is bitcoin?
b) Why does Bitcoin have value?
c) Parts of bitcoin/terms to know:
d) Interesting things about bitcoin:
e) How to buy/sell:
f) Who takes bitcoin?
g) How to keep bitcoins safe:
h) problems and solutions ahead for BTC

Do we need ASIC countermeasures in Dogecoin?

As you know, because Dogecoin uses scrypt like Litecoin does, it's quite a bit more ASIC resilient compared to Bitcoin. This has a major effect on the network, instead of giving the whole mining market away to miners, we're spreading the fun and anyone with a GPU (200kh/s+ for entry level card) or high end CPU (100kh/s?) can join in.
Compare this to the Bitcoin scene, where a top end GPU can get ~800MH/s, but ASIC's can reach 10-50 GH/s now and new ones for 2.5+ TH/s are expected in 2014. It's already completely useless to mine with GPU's, but every time a new generation of miners is released, even older ASIC's can't compete - this cold war style arms race will never end.
Our problem is that while scrypt was assumed to be quite ASIC resilient, there seems to be something released soon targeting it, and while 300KH/s for 8W isn't too scary, it's just the start of the arms race, there's no way to predict how far this will go. But there's good news, we can fix it very quickly if we want to - and we still have some time, they need to ship 300000 of those units to double our network hash rate to attack it.
As we're just starting, we still have the ability to fix this by changing the client. It will introduce a hard break in the network - the client update introducing the change will be mandatory, but maybe preventing an arms race is worth the trouble. A potential fix we could use is mentioned in Vertcoin's annoucement - scrypt's ASIC resilience is based on using a large amount of memory per thread, but instead of fixing that at 128KB (N=10, 210 = 1024 -> scrypt_1024_1_1_256_sp in Dogecoin's source), they use a dynamic N factor that increases every once in a while. Maybe this elaborate system is overkill and we can just decide on increasing N to 12 on block 200000 and call it a day, that will at least force those silly ASIC developers to go back to the drawing board for now while we figure out what to do to kill it forever. By introducing the change on block 200000, we'll have 3 months to get everyone updated with a new client, miners and pools.
I love this community and it would really be a shame if instead of everyone happily mining and tipping, all mining power is concentrated in a few srs businesses with big ASIC's in a year and the only cost effective way to acquire coins is to buy it with dollars from the mining corporations.

Total Network Hash

Vertcoin's "Total Network Hash" rate is at about 6.5 GH/s at the time of this writing. We double this 6.5 GH/s to indicate the comparative amount of mining hash that Scrypt v01, or non Adaptive N coins, generate per unit of Scrypt hardware hashing potential that is now mining Vertcoin.
So Vertcoin now attracts the amount of mining hardware that would produce about 13 GH/s Total Network Hashrate for some Scrypt v01 coin.
Litecoin is of course nearing 200 GH/s, Dogecoin is less than half of Litecoin's Total Network Hashrate at 85 GH/s and Vertcoin is at about 13 GH/s. Feathercoin is in fourth place with about 6.5 GH/s.
  1. Litecoin == 200 GH/s (varies significantly over the medium term.)
  2. Dogecoin == 85 GH/s (varies wildly over the short term)
  3. Vertcoin == 6.5GH/s (13 GH/s) (varies less than other coins)
  4. Feathercoin == 6.4 GH/s
For a relatively new introduction to the coin markets, Vertcoin performance is remarkable. We might have seen Vertcoin falter and fall into weakness, but we are not seeing that. We bottomed around 0.00135 bitcoin value, and now we are seeing a strong rally, a reversal, or series of rallies that retrace naturally to the short term 50% fib areas, and then another leg up ...
The question is of course, how much of the increase in value of these recent rallies, (from the recent bottom), can Vertcoin maintain going forward?
The newest Ace up Vertcoin's sleeve, Multivert mining pool, http://www.verters.com/multivert, where miners point Scrypt v01, (non adaptive N Factor), mining power at this new pool, the pool then mines the most profitable Scrypt v01 coins, sells them on the market for bitcoin, then purchases Vertcoin and pays miners in Vertcoin, this is probably one of the favorable and attractive new mining strategies, (to speculators as well as miners), accounting for some of the recent interest in Vertcoin in the markets, thus, the price increases.
The absolute beauty of this new mining strategy is that to combat this strategy, to mine the more profitable Vertcoin with a Multipool operation, to mine VTC directly, and then DUMP the Vert on the market for bitcoin, and then pay miners in bitcoin, can only be accomplished by having miners point their hashing power at that pool, using vertMINER software, thus, the distribution of the Adaptive N Factor mining software would be of magnitudes greater than it is now to accomplish that.
Vert coin miners understand that mining Vert, selling it for bitcoin, and then paying miners in bitcoin is not a step in the evolution of mining strategies. Perhaps the VTC for BTC exchange by individual miners, or farms, is tenable, but not a general MultiPool strategy.
Vertcoin literally has proven that it is not tenable for a Multipool mining strategy where Vertcoin proceeds would be sold for bitcoin, thus, Vertcoin has a very definable victory here in the mining strategy markets. Along with Vertcoin's ASIC resistance, and strategies up the sleeve for further enhancement of ASIC resistance, Vertcoin puts itself in the spotlight and truly sets an example for CryptoCurrency moving forward.
Vertcoin Multivert mining pool literally TURNS the TABLES on the mining strategy that has pounded so many alts with pool dumps mining the most profitable alt coins, selling market orders for bitcoin, and paying their alt coin mining miners ... in bitcoin.
Moolah and others involved in getting a USD/VTC pair, or exchange for fiat launched is another favorable factor for Vertcoin.

anarchistantilite--coin the remedy for the flop litecoin -- jest of course

Litecoin: It was going places with Gox bi-monthly announcements. But Gox associates were pumping and dumping it, along with [insert conspiracy here]. You thought it was the second coming, now it is just another cryptocurrency.
anarchistantilite--coin has Litecoin specs, it is numero uno litecoin clone. Halves at 840,000 blocks. Differences: Early miners > 10,000 blocks, 500 then 250 coins. Normal reward is 50 coins till halving. 30 second blocks. Retarget every 5 minutes or so. The rest is the same as bitcoin, I mean litecoin.
10k of blocks almost gone in a mining frenzy meaning defending it from the dumpees (2 GH on it). So that cost a bit at MRR. But reward will be back at 50 and sanity will return.
On Yobit (such a surprise), but will be popping on a few other exchanges as well.
Mining at tekyboy, who did a good deal with plenty of bounties to get some shit done. Don't think we got the Twitter guy, so could be a place open. This is welcomed because my bot keeps crashing.
antilitecoin.pw ... got a heavy dump today, but held off the monster machines to a great degree. Next stop is 100 sats.
Fact, the coin is cool, and will endure because 1. we are better players than most, and 2. we know where to push, where to pull back, and how to play long games. REVOLUTION!

Most alt-coins are NOT secure enough, they exist only for entertainment and speculation (Taken from /r/Bitcoin)

TL;DR IMO this guy hates alt-coins.
OP: http://www.reddit.com/Bitcoin/comments/22aw8c/most_altcoins_are_not_secure_enough_they_exist/
(I believe this needs to be posted to /bitcoin[1] as Bitcoin users/enthusiasts need to know the difference between Bitcoin and other cryptocurrencies. About author: I'm subscribed to /bitcoin[2] since 2011, and have been involved in cryptocurrency security research for several years.)
Let's talk about security aspect of cryptocurrencies. I'm afraid an average user knows very little about this topic: he might know that hashrate is needed to protect the blockchain, and that higher hashrate is better, as it implies that attacker needs to spend more to get control of the blockchain.
But there is a plenty of other kinds of attacks (or, rather, economic models of attacks), some of which have much higher practical significance.
Let's start with something simple: there is a straightforward and rigorous model of double-spending attack under condition that attacker has a fraction of total network's hashrate. I highly recommend Meni Rosenfeld's Analysis of hashrate-based double-spending paper (PDF[3] ).
The main takeaway from this paper is that "maximal safe transaction value" is directly proportional to block reward (i.e. amount of coins miners get for each block). It is easy to understand this intuitively: bigger reward means that miners get more money from normal mining, so they will be reluctant to try double-spending attacks. On the other hand, if block reward was negligible, double-spending could be a lucrative source of revenue.
Let's look at numbers: if attacker controls 26% of hashrate and number of confirmations is 6, maximal safe transaction value is 1113 BTC when block reward is 25 BTC. This is pretty cool: you only need to wait 1 hour to make sure you irreversibly received half million USD worth of bitcoins (I assume exchange rate of $450 (Ɖ960k) for 1 Bitcoin).
However, situation is pretty different for alt-coins which have much less valuable block rewards. For example, imagine there is a Foocoin with exchange rate of $1 (Ɖ2.1k) for 1 Foocoin. If Foocoin's block reward is also 25 foocoins, then max save transaction value for 6 confirmations is only $1113 (Ɖ2.4M) USD worth of Foocoins. It doesn't look like Foocoin is suitable for commerce, does it? One could say that Foocoin simply requires larger number of confirmations for larger transactions. But that's wrong: higher number of confirmations helps only under condition that attacker is unable to obtain more than 50% of total hashrate, but for most alt-coins it isn't true.
First of all, let's note that so-called miners simply rent their equipment to "mining pool operators" and are paid in crypto-currency for it. In many cases they don't even care what cryptocurrency they mine as long as they are being paid. See Middlecoin[4] : This pool automatically mines the most profitable scrypt coin, automatically exchanges those coins for bitcoins, and pays out entirely in bitcoins.
So, miners who mine using Middlecoin do not know if their equipment is being used to mine Litecoins or Dogecoins or something else. And they wouldn't care if it is used for attacks on alt-coins, as they are being paid in bitcoins. Let's consider a scenario where Middlecoin-like pool has higher hashrate than Foocoin, e.g. Middlecoin (not Middlecoin specifically, but any pool like that) has 20 GH/s, while Foocoin has 10 GH/s. Here's how one can profit from it:
  1. Buy $1M worth of Foocoins, get them into your wallet.
  2. Make an agreement with Middlecoin: you rent they hashrate for a couple of hours, paying them in bitcoin, slightly above what most profitable alt-coin yields.
  3. Send your foocoins to exchange Bar.
  4. Start mining a private chain which has a double-spend transaction which sends coins to exchange Baz.
  5. After your transaction gets 10 confirmations on the normal chain, convert foocoins to bitcoins on Bar and withdraw them immediately.
  6. After withdrawal transaction is confirmed on Bitcoin network (and thus cannot be reversed), you release the private chain you have mined, causing reorganization. You should have mined 20 blocks by then under if Middlecoin has hashrate which is twice higher than normal Foocoin's hashrate.
  7. Your deposit to exchange Baz is now confirmed, converl your foocoins to bitcoins again, and withdraw immediately. A day later 20 blocks you have mined will get mature, and you'll be able to sell them too.
If Foocoin price doesn't change in process, you can get approximately $1M profit on this attack, as cost of renting a mining pool is approximately equal to value of mined blocks.
In practice, you'll lose some money due to lack of liquidity on exchanges, so profit will be less than $1M.
The conclusion we get from this analysis is that alt-coins which have only a small fraction of total hashrate for a certain mining algorithm are extremely non-secure. And they cannot grow big: as soon as exchanges will have enough liquidity, it will be possible to perform the attack I described, which will result in the price drop.
So almost all alt-coins are simply not suitable for any kind of "real economy" applications. They are doomed to have high volatility, shallow markets, low "max safe transaction value".
One can't deny the fact that it is possible to make money on alt-coins. But that's just gambling. And people who create new alt-coins are in same position as people who build casinos. It is a business, but it is the entertainment sector, not in 'real economy' or 'financial' sectors as some people are trying to pretend.
Bitcoin is one of few cryptocurrencies which are actually serious. It isn't perfect, but attacking Bitcoin is very hard, so transactions worth millions of dollars can be confirmed in matter of hours. Same cannot be said about alt-coins, and this situation won't change unless new cryptocurrency designs will be found.
If there is an alt-coin which is more-or-less secure, it is probably Litecoin. Its hashrate is a significant fraction of total scrypt hashrate, so attacking Litecoin is hard. Interestingly, at some point Dogecoin's hashrate was higher than Litecoin's but it dropped after block reward have dropped. So, again, block reward is important for security.
This has dire implications for alt-coins which have short block reward schedules. If all coins will be mined in two years, this mean that alt-coin will be dead in two years.
(It's worth noting that same problem might affect Bitcoin in future, like in 10 years or so.) Now there is a question: Is there a way to make multiple currencies all of which will be secure? Probably. There are several approaches:

GPU-friendly mining. 1m BTC market cap. 84m coins. 2.5 minute blocks. A Bitcoiner's report on Litecoin.

Litecoin, a Bitcoin-like Internet currency has seen its network gain significant hashing power in recent weeks, but the currency's long-term prospects remain unclear. This post aims to provide more information about the Litecoin network and currency.
In early to mid 2013, Bitcoin mining is likely to become largely unprofitable for GPU-miners due to the rise of efficient Bitcoin mining ASICs. It is expected that many GPUs will be removed from securing the Bitcoin network and will be redeployed for other purposes. Besides Bitcoin mining, there are three such uses for these GPUs: 1) gaming, 2) password recovery and security testing and 3) non-Bitcoin cryptocurrency mining. Since Litecoin is the cryptocurrency with the next greatest hashing power and is most efficiently mined with GPUs, understanding the current status of the Litecoin network and economy is desirable for those studying the options. Below, I have gathered information to help inform a decision on whether to commit resources to Litecoin.
Miners
The current hashrate of the network is roughly 3 gigahashes per second (GH/s). Due to Litecoin's scrypt-based mining algorithm, Litecoin hashrates are generally 1000 times slower than when mining Bitcoin on comparable hardware. Therefore, this hash rate is produced by an amount of hardware that would produce 3 terahashes per second (TH/s) on the Bitcoin newtork. The current 15-day window estimate for Bitcoin hashrate is 40 TH/s meaning the Litecoin network is roughly 7% the strength of the Bitcoin network.

History
Litecoin's genesis block was mined on Thursday Oct 13, 2011 at 03:00 GMT. Since then, over 15.5 million litecoins have been mined in the first 310,000 blocks. The network releases 50 litecoins per block which are targeted to be found evey 2.5 minutes on average. The block reward will halve every 840,000 blocks which will cause the network to produce 84 million litecoins in total.
The currency has traded in the 1.22 mBTC to 17.3 mBTC range since its birth. Trading is highly volatile with 40-50% changes occuring on a daily basis. Most trading volume can be found on the BTC-e exchange (https://btc-e.com) in the LTC/BTC market by a margin of 2:1 over the next highest volume of LTC/USD also at BTC-e. Other supporting LTC/BTC exchanges include Vircurex (https://vircurex.com) and BitParking (https://ltcexchange.bitparking.com).
All-time price statistics ------------------------- BTC - high: 17.69 mBTC on 3/12/2013 low: 1.22 mBTC on 8/15/2012 USD - high: $0.75 on 3/7/2013 low: $0.015 on 8/15/2012 
The current exchange rate for Litecoin at BTC-e is 12.3 mBTC or $0.55 for one litecoin.

Early-adopter advantage
The ability to acquire currency units cheaply through purchase or mining provided an important incentive to Bitcoin's earlier-adopters. By risking the loss of their time and money they have shared in financial gains proportional to the exchange rate and, by extension, the success of the system. Litecoin has a similar early-adopter incentive with one difference. Its launch into an already-sizeable community meant that a greater number of stakeholders existed from the beginning than were aware of Bitcoin in 2009.
A large proportion of early bitcoins were mined when it was extremely unclear if Bitcoin would last beyond a brief experiment. It is then reasonable to expect that many early users did not keep their wallet files or private keys and that a large proportion of early coins will never be spent. While it is difficult to estimate the magnitude of this effect, it provides a potential source of volatility in the future. In contrast, early Litecoin users, most of which were familiar with Bitcoin, could expect that Litecoin's success would make their coins worth keeping. The %-days-destroyed metric tracks what fraction of the money supply has moved since it was mined and for Litecoin is 60.3% versus Bitcoin's 43.7%.
source: http://explorer.litecoin.net, https://blockchain.info/charts/bitcoin-days-destroyed-cumulative
Diversification
Diversification helps to reduce risk and increase reliability of investments and technological systems respectively. Since Litecoin is the second-most established cryptocurrency and is also blockchain-based it may be used easily to diversify Bitcoin-denominated investments. The unique ease of currency exchange beween this currency pair results from each currency's decentralized management and low transfer fees. While current trading volumes and high volatiltiy limit Litecoin's use for significant and stable diversification, more research into LTC/BTC, LTC/USD, and BTC/USD exchange rate relationships is advised.
From a technical standpoint, Litecoin shares many features and the vast majority of its codebase with Bitcoin. Litecoin therefor provides little additional security benefit to the cryptocurrency ecosphere as bugs found in Bitcoin are likely to apply to Litecoin. Mining infrastructure is probably where Litecoin offers the greatest independence from Bitcoin due to Litecoin's use of the scrypt mining algorithm.
Since Litecoin is very similar in use, Bitcoin-accepting merchants and payment processors can support Litecoin payments with minor modifications to the software they are using though at this time only a small number of businesses accept Litecoin.
Development
The core client Litecoin-qt/litecoind is based on Bitcoin-qt/bitcoind. It is currently at version 0.6.3 and is based on the same Bitcoin software version. It is 8 months behind the current Bitcoin client. The Litecoin codebase is maintained at https://github.com/litecoin-project/litecoin as a fork of the https://github.com/bitcoin/bitcoin project. While the same revision control system is in use, the current development model lacks the formal testing and release verification of bitcoin-qt/bitcoind.
Outside the core client codebase, many of the documents and websites created when Litecoin was launched remain untouched, display incorrect information, or have disappeared completely though a number of new sites and services have appeared in recent weeks.
Service Availability
While Litecoin services such as a block explorer, historical charts, and an Instawallet-like web wallet do exist, there are a number of important services that are not yet available. There is no client-side encrypted web-based wallet comparable to Blockchain.info/wallet or the extensive macroeconomic charts at that same site. Mobile software is also limited to a few mining programs with no mobile wallet or exchange rate monitor apps available. Finally, exchange volume is highly centralized on the BTC-e exchange and there is no payment processor that provides any functionality similar to Bit-Pay or Coinbase.
Conclusion
This report has provided information on the Litecoin peer to peer Internet currency and will likely be obsolete within hours of its release in many of the figures quoted. The reader is encouraged to retrieve updated information from the sources included in the report as they will undoubtedly affect any decision on whether to support Litecoin.

Eobot.com FAQ

FAQ https://www.eobot.com/new.aspx?referid=94984
General Questions What is a Bitcoin? Good question; see www.bitcoin.org for more information.
What are your options to withdraw? We currently only allow withdrawals in BTC/LTC/BC/NMC/DOGE/XRP/DRK/RDD/BTS/CURE/PPC/NXT/SYS.
Why can't I deposit or withdraw "real currency", aka fiat (USD/EUJPY/GBP/CNY/RUB/etc.)? Due to international law, we do not allow you to deposit or withdraw fiat currencies. In the USA, there are MSB and FinCen regulations; in Europe, certain countries have banned cryptocurrencies, and in China, the banks aren't allowed to transfer cryptocurrencies. The laws may change in the future.
Why does my "Total Cryptocurrency Value" go down? This is because that display is tied to the exchange rates on other websites. Also see this user generated YouTube video for more information: https://www.youtube.com/watch?v=GucqlMuIXMg
Are their any fees to join or monthly fees? No fees.
Do you speak Spanish/Russian/Chinese? No, only English, but Google Translator works well.
What are the maximums/minimums for withdrawing? There are no maximums. The minimums are small, see the withdraw page for details.
Where can I see the terms and conditions? Please click here for terms and conditions.
Where can I see the privacy policy? Please click here for privacy policy.
Are you hiring? We are always looking for quality talent. If you would like to contribute, then please send your cover letter and resume to [email protected].
Do you have a bug bounty program? Yes, we pay for bugs, so contact us for details or visit us at CrowdCurity.com and submit bugs there!
Do you perform off-chain transactions? No we do not. All cryptocurrencies are sent, usually including miner fees, and can be seen on the blockchain for that respective cryptocurrency. This helps secure the network, makes our transactions transparent, provides an easier way to debug and track down coins, and reduces the chance for fraud. An off-chain transaction would be like what Coinbase could do if both users are Coinbase users and they change coins from one email to another, mark it in the database, and Bitcoin is never actually sent from one wallet to another.
Why does my balance reset after refreshing the page or changing cryptocurrencies? The server updates every 60 seconds and the balances you see updating in real-time are performed with Javascript. If you change pages quickly, or choose a new cryptocurrency, then it will look like it is resetting. However nothign is lost, as whatever cryptocurrency it is set at when the server updates will get the past 60 seconds of mining results.
Help! My account was hacked and withdraws are being made? Eobot is a secure site and has never been compromised. If your account was hacked, then you should change your password, turn on 2FA, and turn on email notifications. There are many unscrupulous Bitcoin sites, and most likely, you used the same password on another site. Never re-use passwords!
Do you have any wallpapers? Yes, you can download wallpaper1 or wallpaper2. Feel free to send us your own creations.
What does Eobot stand for? We have heard everything, let us know your favorite, including: Earn Online Bot, Earn Online Bitcoins Online Tool, Earn Online By Our Tech.
Is this legal? We cannot provide legal advice; make sure cryptocurrencies are legal in your jurisdiction before continuing to use Eobot.
Cloud Mining Questions What are the Cloud Mining fees? For electricity and maintenance, we currently charge a fee of 65% for SHA-256 and 65% for Scrypt. These values will change as difficulty increases, exchange rates change, and newer ASICs come online. These fees are better than our competitors, for instance CEX.IO charges $0.105 per GHS, which is a 81% fee! While GAW charges a 96% fee at current prices!
How long are the Cloud Mining rentals and contracts? Prior to October 11 2014, GHS/KHS contracts had no expiration. Old contracts are not affected. New contracts and rentals, mined or purchased after October 11 2014, are now limited in term for 5 years going forward. See your History tab for expiration dates.
Can I sell my Cloud Mining? No, you cannot sell the cloud shares at this time. This is because we own the hardware and do not want to be stuck if everyone decides to sell at once.
Can I buy Cloud Mining with credit card/USD? Yes, but please keep in mind you cannot sell or convert the Cloud Mining.
Can I buy Cloud Mining with cryptocurrency? Yes, deposit the cryptocurrency and then convert it to your choice of Cloud Mining.
What are the maximums/minimums when making a credit card purchase to buy Cloud Mining? The minimum is 1.0 GHS and 10.0 KHS and there is no maximum at this time.
Can I buy a Cloud Mining that mines in Scrypt? You can use the Cloud Mining SHA-256 hashing power to mine other currencies by automatically converting them as you mine, but the earnings will still be tied to SHA-256/Bitcoin difficulty, not Scrypt/Litecoin difficulty.
What is the difference between Cloud Mining SHA-256 and Cloud Mining Scrypt? One is tied to the difficulty in mining SHA-256 cryptocurrency (Bitcoin) and the other is tied to the difficulty in mining Scrypt cryptocurrency (Litecoin). This means that if history is any indication of the future, then the Cloud Mining Scrypt won't decrease as fast as the Cloud Mining SHA-256.
What does 1 instance of Cloud Mining SHA-256 and Cloud Mining Scrypt equal? 1 of Cloud SHA-256 equates to 1.0 GHS of SHA-256 mining power, while 1 of Cloud Scrypt equates to 1 KHS of Scrypt mining power.
Can I change the pool that my Cloud mines on? No, you cannot; this may change in the future.
What hardware is behind the Cloud Mining? The hardware varies from custom ASICs to GPUs. The ASICs are behind the SHA-256 and the GPUs are behind the Scrypt.
Can I RDP (remote desktop) into my Cloud Mining? No, you cannot at this time; we will run the servers for you.
What is the Cloud Mining Pre-Order? These are the same as the other Cloud Mining, but they will start mining on a later date. For instance, a Cloud Mining Pre-Order October 2014 will start mining on October 1, 2014.
Software/Miner Questions Why is it stuck on "initializing...please wait 5 minutes"? We recently changed our Scrypt pool, so this messge will show and the stats and speed won't show under your account. See pool info page for more info.
Why does it show as a trojan/virus? This is a false-positive that many of the popular antivirus programs report. For now you can ignore it, or try another free antivirus, like Microsoft Security Essentials. Hackers use something similar programs to make money off of people's computers, so that is why it shows up as a virus.
Why does Chrome block the download as malicious? This is another false-positive. Simply, go to your Chrome settings, scroll to the bottom and click on "Show Advanced Settings". Go to the Privacy section and uncheck "Enable phishing and malware protection". You will only do this temporarily. Then proceed to download our software. Then return to your privacy settings and recheck Enable Phishing to further protect you.
Do you have a Mac or Linux version? Yes, see the Pool Info under the Account page.
How do I use cgminer? See this English PDF tutorial for cgminer, or Spanish version, created by one of our members, for a simple walk-through.
How can I increase the speed? Important to increase speed: The default cgminer settings do not include hardware specific flags, which you may find here in the Litecoin Mining Hardware Comparison. Failing to use the proper flags can result in performance decreases in excess of 50%.
What do the intensity settings relate to? This is the same as cgminer flag --intensity. Low is 11, normal is none, high is 15, very high is 17, extreme is 19.
Can I use one account for multiple computers on same IP address? Yes, it will add your speed/rates together, you can use as many computers as you want.
Can I connect to the pool manually, through cgminer or bfgminer? Yes, see the Pool Info under the Account page.
Do you use Bitcoin and Litecoin? Yes, we are the easiest miner to use with BTC and LTC and convert on the backend automatically.
What do you use on the backend? We use cgminer, bfgminer, pooler's CPU miner, and a variety of pools.
Can I mine any cryptocurrency? Yes, regardless if you use SHA-256 or Scrypt (BTC vs LTC mode), you can earn and mine any cryptocurrency.
Can I use an ASIC? Yes, simply choose the option and run as GPU mode. Devices that work with bfgminer will work, for instance USB Block Eruptors or Butterfly Labs ASICs. You can also contact us for pool information for other ASICs.
What is the best graphics card/computer to buy? Either use a high end ATI Radeon card, or buy one of the USB Block Eruptor devices on Ebay/Amazon or a similar online store.
What drivers do I need for USB mode? http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
Why doesn't GPU mode work? You may need to download the OpenCL drivers; get them from here: http://developer.nvidia.com/opencl
Where can I get the .NET framework? Try Windows Update, or use Microsoft Web Platform Installer.
Can I use a proxy server? Yes, edit intensity.txt and put the details in there, for example, add "--proxy=http://mycompany-http-proxy:8080"
Where can I download the software? Download from link here
Can I use custom flags/change intensity? Yes, you can put in whatever custom flags/parameters/arguments you want. Edit the "resources/intensity.txt" file. Put in whatever you want, like for GPU mode: "--intensity 12 --shaders 1024" or for CPU mode (number of threads): "-t 32"

Since Litecoin is very similar in use, Bitcoin-accepting merchants and payment processors can support Litecoin payments with minor modifications to the software they are using though at this time only a small number of businesses accept Litecoin.
Development
The core client Litecoin-qt/litecoind is based on Bitcoin-qt/bitcoind. It is currently at version 0.6.3 and is based on the same Bitcoin software version. It is 8 months behind the current Bitcoin client. The Litecoin codebase is maintained at https://github.com/litecoin-project/litecoin as a fork of the https://github.com/bitcoin/bitcoin project. While the same revision control system is in use, the current development model lacks the formal testing and release verification of bitcoin-qt/bitcoind.
Outside the core client codebase, many of the documents and websites created when Litecoin was launched remain untouched, display incorrect information, or have disappeared completely though a number of new sites and services have appeared in recent weeks.
Service Availability
While Litecoin services such as a block explorer, historical charts, and an Instawallet-like web wallet do exist, there are a number of important services that are not yet available. There is no client-side encrypted web-based wallet comparable to Blockchain.info/wallet or the extensive macroeconomic charts at that same site. Mobile software is also limited to a few mining programs with no mobile wallet or exchange rate monitor apps available. Finally, exchange volume is highly centralized on the BTC-e exchange and there is no payment processor that provides any functionality similar to Bit-Pay or Coinbase.
Conclusion
This report has provided information on the Litecoin peer to peer Internet currency and will likely be obsolete within hours of its release in many of the figures quoted. The reader is encouraged to retrieve updated information from the sources included in the report as they will undoubtedly affect any decision on whether to support Litecoin.
