Overview
- The proposal entered mandatory signaling at block 961,632 and enforcing nodes began rejecting non‑signaling blocks, producing a separate chain that mined only two blocks and halted at block 961,633.
- The main Bitcoin chain continued to advance, leaving the BIP-110 branch dozens to more than 100 blocks behind and preventing the fork from completing a full 2,016-block period needed for a difficulty reset.
- A pseudonymous group called Roughnecks mined the two enforcing blocks using Ocean’s DATUM endpoint, which showed roughly 257 PH/s, and Michael Saylor estimates the fork controls about 0.15% of total hashpower.
- At the fork’s current mining rate it would take on the order of decades to reach the first difficulty adjustment, and BIP-110 contains no built-in replay protection, creating custody and transaction risks for users and exchanges.
- Support was weak before enforcement, with only 51 of 2,016 prior blocks signaling (about 2.5%) and essentially no miner signaling since mandatory mode began, underscoring that protocol changes need broad miner and ecosystem backing to be effective.
