Bitcoin nears end of BIP-110 signaling window with 185 blocks left

Only 48 of 1,831 observed blocks signaled support as of Aug. 7, leaving Bitcoin short of the 55% threshold required in the 2,016-block period even if all remaining blocks signaled.

Bitcoin is approaching the close of the BIP-110 signaling period, a proposed temporary soft fork intended to shrink block data. Under the plan, nodes that enforce the proposal will reject blocks that do not signal support once the signaling period ends, even though Bitcoin does not automatically require every network participant to adopt the proposal.

CryptoSlate reports that, as of 14:41:49 UTC on Aug. 7, a third-party monitor recorded only 48 signaling blocks out of 1,831, or 2.62%. The monitor said there are 185 blocks left before the current signaling period closes, and BIP-110 calls for 1,109 signaling blocks within a 2,016-block window to meet its 55% threshold.

Even if all 185 remaining blocks signaled, the period would finish at 233 of 2,016 blocks, about 11.6%, according to the same monitor math. From height 961,632, enforcing nodes reject blocks that do not signal bit 4, which can create divergent block acceptance depending on which node rules are being enforced.

The article also outlines a timeline for when mandatory signaling, lock-in, and reduced-data rules would occur for BIP-110-enforcing nodes, noting that these rules would not bind every Bitcoin participant. CryptoSlate adds that a Bitcoin Core pull request implementing BIP-110 closed unmerged on March 26, and a Core contributor said in a personal capacity that Core does not enforce the proposal, while a mining pool outlined separate signaling and non-signaling endpoints and said its switch would begin July 15.
