Overview
- Nodes running BIP-110 began rejecting non-signaling blocks at block 961,632 on Saturday, creating a breakaway chain that produced just two blocks before falling far behind the main Bitcoin network.
- Public miner signaling for BIP-110 remained about 2.5 percent, far short of the 55 percent (1,109 of 2,016 blocks) needed for miner lock-in, so the minority branch lacks the hashpower to keep pace.
- The minority chain inherited Bitcoin’s current mining difficulty, which makes block times hours apart and could keep its next difficulty adjustment many months away unless many miners join.
- Because transactions are initially valid on both chains, moving coins on the minority fork risks replay attacks that can spend the same BTC on the main chain, prompting developers to tell ordinary holders to avoid moving funds.
- Infrastructure operators face immediate choices as wallets and exchanges weigh temporary pauses on deposits and withdrawals while Bitcoin Knots warns of chainstate and validation hazards for non-enforcing clients and the wider debate over who controls consensus continues to play out.
