Bitcoin’s BIP 110 fork deadline nears with miner support at zero
BIP-110, a proposed soft fork intended to restrict non-financial data on the Bitcoin blockchain, is nearing its deadline with virtually no support from miners or the broader network. Influential figures like Michael Saylor and Adam Back have publicly opposed the measure, arguing that it sets a dangerous precedent for consensus changes.
Why it matters
The failure of BIP-110 highlights Bitcoin's extreme resistance to protocol changes and reinforces the network's decentralized governance model, where consensus requires overwhelming community and miner agreement.
BIP-110 , formally titled the Reduced Data Temporary Soft Fork, is basically a fight over what Bitcoin block space is for.
Bitcoin transactions can carry money and extra data. An OP_RETURN section is the obvious “note field” for small bits of data within transactions, and data pushes are another route - where users can place larger chunks of raw data inside Bitcoin script or witness data. Ordinals, inscriptions and some token schemes use those paths to put images, text or token metadata onchain.
BIP-110 would temporarily tighten those paths for one year. It would cap OP_RETURN at the old small size, block most arbitrary data chunks above 256 bytes, and restrict some script formats used mainly for data storage.
Supporters say this keeps Bitcoin focused on payments and lowers node burden, but critics think it turns a policy fight into a consensus rule and tells users which transactions are “acceptable.”
