Bitcoin’s BIP-110 enters mandatory signaling with miner support below 3%

Bitcoin Improvement Proposal 110 entered its mandatory-signaling phase at block 961,632 on Saturday, with miners signaling support in just 51 of the preceding 2,016 blocks, or 2.53%, well below the 55% threshold required for early activation, according to the BIP-110 monitor.Starting at block 961,632, nodes enforcing BIP-110 began rejecting blocks that did not set version bit 4, while ordinary Bitcoin nodes continued accepting both signaling and non-signaling blocks. A minority BIP-110 branch subsequently emerged, but quickly fell behind the dominant chain.The low signaling rate makes a sustained rival chain unlikely without substantially greater miner participation. With relatively little mining support, a BIP-110 branch could advance slowly or stop producing blocks altogether.The milestone tests whether supporters can advance a contentious consensus change without broad miner backing, potentially separating enforcing nodes from the dominant chain and escalating a dispute over how Bitcoin’s block space should be used.BIP-110 seeks temporary limits on Bitcoin dataWritten by pseudonymous developer Dathon Ohm, BIP-110 proposes additional consensus restrictions lasting roughly one yea...
