Bitcoin splits as BIP110 fork falls 18 blocks behind main chain
AI Market Summary
Bitcoin experienced a consensus split tied to the controversial BIP110 "one-year rule" proposal, with the BIP110 chain lagging the main chain by 18 blocks and still lacking miner support to persist. The fork elevates near-term operational risk (reorgs, replay/confusion across chains) and raises settlement uncertainty, especially for users transacting or selling assets on the minority fork. Activation thresholds appear far from being met, but market microstructure risk is elevated.

Huoxing Finance reported that the Bitcoin network saw a chain split on Aug. 9 tied to BIP110. Nodes running software that supports the proposal began rejecting blocks at height 961,632 if they did not carry a support signal.
At the time of reporting, Bitcoin's main chain had advanced to block 961,651, while the BIP110 fork had only reached block 961,633, leaving it 18 blocks behind.
BIP110 is a one-year rule-change proposal designed to curb the inclusion of non-financial data in Bitcoin transactions, including applications such as Ordinals inscriptions. Activation required at least 1,109 signaling blocks (55%) within a two-week window of 2,016 blocks. In the prior signaling period, only 51 blocks signaled support, or 2.53%.
The BIP110 chain still needs additional miner backing to remain viable. Under the proposal's rules, the fork must reach block 963,648 to lock in the change, with enforcement set to begin at block 965,664 and last about one year.
Previously, Bitcoin developer Kevin Loaec warned that if a fork linked to the controversial BIP110 proposal materializes this weekend, holders who sell tokens on the forked chain could risk having their actual BTC transferred away.
