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

Odaily Odaily News: The Bitcoin BIP-110 forced signaling window will open at block height 961632, expected around August 9, 2026. As of 8:40 AM (EDT) on July 27, the chain height is 959842, approximately 1790 blocks away from this activation block. The current BIP-110 signaling support rate is around 2.64%.
BIP-110, officially named "Reduced Data Temporary Softfork," proposes to limit the size of certain data fields within Bitcoin transactions, targeting Ordinals-like inscriptions, large OP_RETURN payloads, and similar high-data-volume use cases. If activated, the restrictions will take effect at block 965664 and automatically expire after 52,416 blocks (approximately one year).
Current signaling support primarily comes from Ocean, independent miners, and small-scale operators. Major mining pools such as Foundry, Antpool, ViaBTC, and F2pool have not yet switched to supporting the proposal. Foundry has requested clients to vote based on their average hashrate; only when “support” votes exceed 51% of the participating weighted hashrate will the pool switch all its blocks to signaling support.
If the current signaling level persists until block 961632, nodes enforcing BIP-110 will reject blocks that have not signaled version bit 4 and will instead 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 most cumulative proof of work.
