Bitcoin splits on BIP110; proposal chain trails mainnet by 18 blocks
AI Market Summary
Bitcoin has split into a BIP110 signaling fork and the main chain, with the BIP110 chain ~18 blocks behind due to limited miner signaling. While activation thresholds appear far from met (2.53% support in the prior cycle), the episode highlights governance friction and potential short-term operational risk (reorg/confusion) for miners, exchanges, and indexers. The market focus is on whether miner support materializes before lock-in and enforcement windows.

Odaily Planet Daily reported that the Bitcoin network has split following activity tied to BIP110. Nodes running the proposal began rejecting blocks at height 961,632 that did not carry the required support signals. The main Bitcoin chain has advanced to block 961,651, while the BIP110 fork chain has reached only 961,633, leaving it 18 blocks behind.
BIP110 is a one-year rule-adjustment proposal intended to curb the inclusion of non-financial data in Bitcoin transactions, including uses such as Ordinals inscriptions. For activation, it needs signaling from at least 1,109 blocks (55%) within a 2,016-block period of roughly two weeks. In the prior signaling window, only 51 blocks signaled support, or 2.53%.
The BIP110 chain still needs additional miner support to keep progressing. Under the proposal's timeline, the chain must reach block 963,648 to lock in the rules. Enforcement would then begin at block 965,664 and remain in effect for about one year. (The Block)
