The deadline for Bitcoin data limit proposal BIP-110 is approaching, with miner support for the proposal remaining near zero.

Bitcoin’s BIP-110 proposal is approaching its early August deadline, yet miner support for the measure remains below 1%, signaling significant resistance to the initiative. Officially titled “Temporary Soft Fork for Reducing Data”, BIP-110’s core controversy centers on restricting non-financial data on the Bitcoin blockchain. The proposal aims to cap OP_RETURN data capacity within a year, ban most arbitrary data exceeding 256 bytes from being written to the chain, and limit certain script formats primarily used for data storage. Supporters argue the plan would refocus the Bitcoin network on its payment function and reduce node operational burdens; opponents counter that it would escalate policy disputes over block space usage into consensus rule changes, effectively determining which transactions qualify as “acceptable”. Strategy founder Michael Saylor and Blockstream co-founder Adam Back have both publicly opposed BIP-110. Saylor remarked, “There are 110 things more dangerous than junk data”, adding that the proposal would “turn the junk data debate into a consensus change, invalidating some currently valid transactions that pay fees”. Back stated that if supporters cannot accept the status quo, they may choose to fork, but “Bitcoin will not join”. Data shows BIP-110 uses a user-activated soft fork mechanism with a 55% miner signaling threshold, though miner signaling rates have never topped roughly 1% to date, with the current cycle sitting at 0 and no major mining pools backing the measure. The share of nodes running BIP-110 software also remains in the single digits, primarily from Bitcoin Knots users. The proposal’s current signaling cycle will end around block height 959,615, with a voluntary lock-in period expected in early August and activation targeted for around September. If broad support is still absent by then, the initiative could result in a minority of nodes forming a separate chain.
