In my previous article, I explained why I think Bitcoin censorship is coming without majority of miners being forced to censor transactions. I am pleased with the discussions it brought and I would like to clarify some points. Before you choose to discuss, please read the original article and this article. I know it is […]
Note: A lot of people think this is purely about >50% attack. Not true, here’s how this unfolds with 10% of censoring hashrate. Bitcoin is often said to be anonymous and uncensorable.
