Bitcoin has progressed to block 961,632, initiating the mandatory signaling window for BIP‑110, a contentious proposal intended to temporarily limit the inclusion of non‑financial data on the blockchain.
The signaling phase began at approximately 19:35 UTC on Saturday, with miner support rarely climbing above 2.5%—far below the 55% threshold needed for activation.
Notable industry figures, including Strategy chairman Michael Saylor and Blockstream CEO Adam Back, have expressed strong opposition to the plan.
Advocates are promoting BIP‑110 as a user‑activated soft fork (UASF), which would depend on node operators rather than miners to enforce the change. Under this model, users would upgrade their node software to reject blocks from miners that do not signal support for BIP‑110, pressuring miners to comply or risk being excluded.
Proponents cite the 2017 activation of SegWit through BIP‑148 as a historical precedent, noting that it succeeded despite insufficient miner support and allowed digital signatures to be separated from transaction data.
