Bitcoin developer Chris Guida has rebased a proof-of-work change originally written by fellow developer Luke Dashjr in 2017 onto the recent Bitcoin Knots codebase. The code has not been scheduled for activation, and Guida described it as a contingency measure rather than an imminent fork.
Proposal details and threshold
BIP-110 is a temporary soft fork proposal that would restrict arbitrary data embedded in Bitcoin transactions for roughly one year, including restoring the 83-byte OP_RETURN consensus limit. Early lock-in requires 55% miner signaling — that is, 1,109 blocks out of a 2,016-block window.
Timeline and current signal rates
If that threshold is missed, the forced signaling window begins at block 961,632, expected to occur on or around August 8 or 9. Nodes running BIP-110 would then reject blocks that do not signal support. Lock-in is expected no later than block 963,648, with activation targeted at roughly block 965,664.
As of 8:15 a.m. EDT on August 7, 2026, the chain tip stood at block 961,425, leaving 207 blocks before the forced window opens. Only 47 blocks out of 1,818 have signaled BIP-110 support, putting the current signaling rate at roughly 2.59%.
