Bitcoin BIP-110 Forced Signaling Window Opens in Less Than Two Weeks, Current Support Rate ~2.64%

Odaily Planet Daily News: The forced signaling window for Bitcoin BIP-110 will open at block 961,632, expected around August 9, 2026. As of 8:40 AM EDT on July 27, the on-chain height is 959,842, approximately 1,790 blocks away from the target. The BIP-110 signaling support rate stands at about 2.64%.
BIP-110, officially named "Reduced Data Temporary Softfork," proposes to limit the size of certain data fields in Bitcoin transactions. It primarily targets Ordinals-like inscriptions, large OP_RETURN payloads, and similar high-data-use cases. If activated, the restriction will take effect at block 965,664 and automatically expire after 52,416 blocks, roughly one year.
Current signaling support mainly comes from Ocean, independent miners, and small-scale operators. Major mining pools such as Foundry, Antpool, ViaBTC, and F2pool have not yet switched their support. Foundry has asked clients to vote based on average hashrate; only if "support" votes exceed 51% of the participating weighted hashrate will the pool switch all its blocks to signal support.
If the current signaling level persists until block 961,632, nodes implementing BIP-110 will reject blocks that do not signal version bit 4 and will follow the minority of blocks that do signal. Unupgraded nodes will continue to accept both signaling and non-signaling blocks and will follow the chain with the highest cumulative proof-of-work.
