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

Odaily Planet Daily News Bitcoin's BIP-110 mandatory signaling window will open at block 961632, estimated to occur around August 9, 2026. As of 8:40 AM EDT on July 27th, the on-chain height is 959842, approximately 1790 blocks before this activation block. The current support rate for BIP-110 signaling is about 2.64%.
BIP-110, officially named "Reduced Data Temporary Softfork," proposes to limit the size of certain data fields within Bitcoin transactions, primarily targeting Ordinals-like inscriptions, large OP_RETURN payloads, and similar high-data-volume uses. If activated, the restrictions will take effect at block 965664 and will automatically expire after 52416 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 support. Foundry has requested 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 961632, nodes implementing BIP-110 will reject blocks that have not signaled version bit 4 and will follow the minority of blocks that do signal. Non-upgraded nodes will continue to accept both signaling and non-signaling blocks and will follow the chain with the highest cumulative proof-of-work.
