Разработчик биткоин коре курнул?
Before the AMA, I had been up all night and I was really feeling the effects. So, I took a 15-minute nap just before the AMA. Upon waking up, my team told me there was an interesting proposal from a Bitcoin Core developer. I read it for a few seconds. It involved something called a “reorg”. While I know it’s technically possible for a rollback in a 51% attack scenario, it never occurred to me that it is also technically possible to change one transaction and keep all other transactions intact, while hugely incentivizing the miners. The discussion was already pretty hot on Twitter, so I mentioned it in the AMA as something that was suggested. Little did I know, it was a taboo topic. Lesson learned.
