Bitcoin Minority Fork Emerges After Nodes Reject Non-Signaling Block

A minority fork of Bitcoin has emerged after nodes enforcing BIP-110 rejected a non-signaling block at height 961,632. This event occurred on August 9, marking the start of the proposal's mandatory-signaling window.

The split began when AntPool mined a non-signaling block, while Roughnecks produced a competing compliant block through OCEAN. As a result, nodes enforcing BIP-110 rejected AntPool's block and followed the alternative branch.

The main network has moved ahead considerably faster than the minority branch due to limited hash power supporting the enforcing fork. Block production in the minority chain can take much longer than Bitcoin's standard target of roughly one block every 10 minutes.

BIP-110 does not provide automatic replay protection before its later activation stage, creating additional risks when coins are moved. Developers have cautioned holders against treating the split as a risk-free airdrop opportunity.
