The minority chain mined two blocks in eight hours, then froze. With 99.85% of hashpower on the original chain, the Reduced Data Temporary Softfork is the most decisive governance rejection since SegWit2x. Its backers are now talking about replacing the miners entirely. Summary BIP-110, the Reduced Data Temporary Softfork, triggered a chain split at block 961,632 on August 8, 2026. The minority chain produced two blocks in eight hours, then stalled, while the main network continued at its normal pace and pulled dozens of blocks ahead. Only 2.53% of blocks signaled support during the mandatory window, far below the 55% threshold the proposal itself set for activation. Roughly 99.85% of Bitcoin’s hashpower stayed with the original chain. Michael Saylor published a 110 point essay opposing the proposal, calling it “extremely dangerous” and arguing that rejecting valid, fee paying transactions sets a precedent that could be used to censor any class of Bitcoin activity in the future. The fork exposed holders to replay attack risk because BIP-110 included no replay protection, meaning a transaction broadcast on one chain could be valid on both, potentially causing unintended fund transfe...
