BIP 110

A 2026 soft-fork proposal to keep non-payment data out of blocks, activated by miner signaling with a mandatory window. Before block 961,632 signaling was voluntary; from 961,632 the BIP 110 software rejected every block that did not signal. Voluntary support peaked at 2.53%. At block 961,632 on 8 August 2026 the BIP 110 nodes rejected a non-signaling block and split off on their own chain. Bitcoin continued normally.

The rejection is the network working as designed. Nodes vote on the rules they will enforce, miners vote with hashrate on which chain to extend, and a rule change without both never arrives. The minority chain later switched to a different proof of work (BLAKE2b) with a 300 KB block limit, sharing nothing with Bitcoin but a copied history. Saylor’s line covers it: “Consensus is earned, not declared.”
