A leaked chat has revealed plans to let a trusted group alter Bitcoin data retroactively. It involves giving a trusted committee power to censor and replace blockchain data deemed illegal. It threatens Bitcoin’s core value of censorship resistance and blockchain immutability. A leaked conversation has revealed that developer Luke Dashjr may be considering a hard fork that could give a trusted committee the power to censor data on the blockchain. This is an idea that strikes at the heart of Bitcoin’s promise of censorship resistance.
