Bitcoin's BIP-110 enforcement starts at height 961,632, with adoption still waiting on hashpower and economic support. Editor-in-ChiefCryptoSlateAug. 7, 2026at 7:40 pm GMT2 min readBitcoin's BIP-110 is nearing its enforcement boundary, but observed miner signaling is still only 2. 62%. From height 961,632, enforcing nodes will reject non-signaling blocks, which could split block acceptance between different Bitcoin rule sets. The remaining window is too small to meet the 55% threshold, so the first post-deadline blocks will show whether miners follow. Bitcoin nears the deadline for BIP-110, a proposed temporary soft fork that would shrink block data. Once the current signaling period ends, nodes enforcing it will reject blocks that do not signal support. A third-party monitor showed only 48 of 1,831 blocks signaling as of 14:41:49 UTC on Aug. 7, just 2. 62%, with 185 blocks left before the period closes. BIP-110 requires1,109 signaling blocksin a 2,016-block period to meet its 55% threshold. Even if every one of those 185 remaining blocks signaled, the period would finish at 233 of 2,016, or about 11. 56%. Different rules at height 961,632From height 961,632, continuouslyenforcing BIP-110 nodesreject blocks that do not signal bit 4. Nodes followingexisting Bitcoin rulesmay accept the same blocks if they otherwise satisfy those rules. The result can be divergent block acceptance, while any sustained enforcing branch depends on miners producing BIP-110-valid work after the boundary. Under the proposal, mandatory signaling runs through block 963,647, lock-in won't happen once the height reaches 963,648, and the reduced-data rules activate at 965,664. That schedule governs BIP-110-enforcing nodes without binding every Bitcoin participant. The 2. 62% reading measures version bits in observed blocks, andthe monitor saysit sources block data from mempool. space and checks each block's version field for bit 4. BIP-110 signaling stands at 2. 62%, with mandatory signaling set to begin at block 961,632 and possible rule divergence afterward. ABIP-110 implementation pull requestin the Bitcoin Core repository closed unmerged on March 26. Core contributor Antoine Poinsotwrote in a personal capacityon June 4 that Core does not enforce the proposal. Mining poolOCEANannounced separate signaling and non-signaling endpoints and said itsdefault would switch on July 15. Confirming that the switch actually took place and that every miner using the pool now enforces BIP-110 would require independent verification. CryptoSlate Daily BriefDaily signals, zero noise.

Alternative Bitcoin node implementation Bitcoin Knotsused its Aug. 7 releaseto warn that older non-enforcing software, explicitly including current Bitcoin Core, could stop fully validating BIP-110 rules and leave chainstate unsafe in some scenarios. Independently reproducing the Core-specific warning on Bitcoin Core or on mainnet remains outstanding. A July 17BlockSlop technical write-upreproduced a narrower late-upgrade problem on regtest using enforcing and non-enforcing Knots builds. A data directory could retain a block accepted under the old rules after the operator switched builds because normal startup did not reconnect the inherited history. The test left out physical database corruption or a mainnet incident. Knots thenmerged a safeguardthat scans inherited headers for mandatory-signaling violations, invalidates offending blocks, and reorganizes. Transaction or script violations that are not visible in headers still need reconnection validation and can require reindexing. The first blocks after height 961,631 will reveal which miners change signaling and whether an enforcing chain accumulates work. Measuring economic support would take separate evidence, such as exchange listings, node adoption data, or holder behavior. 1H+0. 33%24H+0. 92%7D+3. 23%30D+4. 40%60D+2. 29%90D-19. 62%Bitcoinis+0. 92%over the past 24 hours and currently sits at rank #1by market cap.
