BIP-110 Mandatory-Signaling Phase Kicks In with Low Miner Support
Bitcoin Improvement Proposal (BIP) 110 has entered its mandatory-signaling phase at block 961,632, but miner support remains low. According to the BIP-110 monitor, only 51 of the preceding 2,016 blocks contained signaling support, representing just 2.53% of total blocks.
This is well below the 55% threshold required for early activation, making a sustained rival chain unlikely without greater miner participation. In the mandatory-signaling phase, 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.
The proposal, written by pseudonymous developer Dathon Ohm, seeks temporary limits on Bitcoin data to discourage inscriptions and other non-monetary data that increase storage and bandwidth costs for node operators. Critics argue that the restrictions could divide Bitcoin and cause nodes to reject transactions permitted under the network's existing rules.
