A Guide to Bitcoin (Part II): A deep dive into the Bitcoin ...
Homelab collective ressources post!
Hey guys! I'm fairly new to this sub and to having a home lab in general and I found this community to be so kind and helping, I wanted to give back what I've learned. I'm seeing a lot of questions asked around on improvements and on what to do with x extra hardware so I thought it would be nice to have a thread to regroup that.
I'll put here some stuff I gathered and the most common questions I've seen, feel free to contribute and i'll update the post along.

Once MRO value increases a lot, block penalties will become more critical of an issue. Pools will fix this issue by placing a limit on number and size of transactions. Transaction fees will go up, because the pools will naturally accept the most profitable transactions. It will become very expensive to send with more than 0 mixin. Anonymity benefits of ring signatures are lost, and the currency becomes unusable for normal transactions.” (https://bitcointalk.org/index.php?topic=583449.msg6830475#msg6830475) -2773: "The CryptoNote developers didn't want blocks getting very large without genuine need for it because it permits a malicious attack. So miners out of self-interest would deliberately restrict the size, forcing the network to operate at the edge of the penalty-free size limit but not exceed it. The maximum block size is a moving average so over time it would grow to accommodate organic volume increase and the issue goes away. This system is most broken when volume suddenly spikes."

There are a very few exceptions, almost certainly including this one. I don't expect a really dominant GPU miner any time soon, maybe ever. GPUs are just computers though, so it is certainly possible to mine this on a GPU, and there probably will be a some GPU miner, but won't be so much faster as to put small scale CPU miners out of business (probably -- absent some unknown algorithmic flaw). Everyone focuses on botnets because it has been so long since regular users were able to effectively mine a coin (due to every coin rapidly going high end GPU and ASIC) that the idea that "users" could vastly outnumber "miners" (botnet or otherwise) isn't even on the radar. The vision here is a wallet that asks you when you want to install: "Do you want to devote some of you CPU power to help secure the network. You will be eligible to receive free coins as a reward (recommended) [check box]." Get millions of users doing that and it will drive down the value of mining to where neither botnets nor professional/industrial miners will bother, and Satoshi's original vision of a true p2p currency will be realized. That's what cryptonote wants to accomplish with this whole "egalitarian mining" concept. Whether it succeeds I don't know but we should give it a chance. Those cryptonote guys seem pretty smart.

One of the hardest I’ve ever seen] -3571: "Tacotime wanted the thread name and OP to use the word privacy instead of anonymity, but I made the change for marketing reasons. Other coins do use the word anonymous improperly, so we too have to play the marketing game. Most users will not bother looking at details to see which actually has more privacy; they'll assume anonymity > privacy. In a world with finite population, there's no such thing as anonymity. You're always "1 of N" possible participants. Zero knowledge gives N -> everyone using the currency, ring signatures give N -> your choice, and CoinJoin gives N -> people who happen to be spending around the same amount of money as you at around the same time. This is actually the critical weakness of CoinJoin: the anonymity set is small and it's fairly susceptible to blockchain analysis. Its main advantage is that you can stick to Bitcoin without hard forking. Another calculated marketing decision: I made most of the OP about ring signatures. In reality, stealth addressing (i.e. one-time public keys) already provides you with 90% of the privacy you need. Ring signatures are more of a trump card that cannot be broken. But Bitcoin already has manual stealth addressing so the distinguishing technological factor in CryptoNote is the use of ring signatures. This is why I think having a coin based on CoinJoin is silly: Bitcoin already has some privacy if you care enough. A separate currency needs to go way beyond mediocre privacy improvements and provide true indistinguishably. This is true thanks to ring signatures: you can never break the 1/N probability of guessing correctly. There's no additional circumstantial evidence like with CoinJoin (save for IP addresses, but that's a problem independent of cryptocurrencies)."

March 2015 – tail emission added to code
March 2016 – monero hard forks to 2 min block and doubles block reward
There basically two things in here that can be used to attack Monero:
Crippled miner Gave unfair advantage to those brave enough to risk money and time to optimize and mine Monero.
Fast curve emission non-bitcoin-like curve as initially advertised and as it was widely accepted as suitable
Though we have to say two things to support current Monero community and devs:
The crippled miner was coded either by Bytecoin or CryptoNote, and 100% solved within a month by Monero community
The fast curve emission was a TFT miscalculation. He forgot to consider that as he was halving the block target he was unintentionally doubling the emission rate.
