Bitcoin's Next Soft Fork: A Maintenance Exercise
Matt Corallo, a long-time Bitcoin developer and co-author of BIP-54, explains that the upcoming soft fork, known as the Great Consensus Cleanup, is aimed at addressing four legacy bugs in Bitcoin's consensus rules. Corallo, who thinks there's an 80% chance the upgrade will be Bitcoin's next soft fork, describes it as a practical cleanup rather than a major win. The soft fork is expected to address issues like quantum resistance and denial-of-service vectors among miners, and is seen as a necessary step for developers who haven't yet experienced a soft fork.
