BIP 110 Deadline Approaches, Raising Questions Over Bitcoin’s Next Upgrade Path

Bitcoin’s BIP 110 proposal nears activation deadline with miners showing little interest

Bitcoin’s BIP 110 proposal, which aims to restrict the use of blockchain space for non-financial data, is approaching its deadline without meaningful support from miners. Despite attracting significant attention and debate, the proposal has received less than 1% miner signaling, reflecting strong resistance across the network.

Known as the Reduced Data Temporary Soft Fork, BIP 110 focuses on the ongoing debate over what Bitcoin’s block space should be used for and whether the network should prioritize financial transactions over data storage applications.

Bitcoin transactions can include both payments and additional information. The OP_RETURN feature allows users to attach small amounts of data, while other methods using scripts and witness data have enabled larger data entries. These tools have been used by projects involving Ordinals, inscriptions, and token systems that store images, text, and metadata directly on Bitcoin.

Under BIP 110, these data storage methods would face temporary restrictions for one year. The proposal would restore a smaller OP_RETURN limit, block most arbitrary data entries larger than 256 bytes, and reduce the use of certain script formats mainly intended for data storage.

Supporters argue that the change would help maintain Bitcoin’s focus as a digital money network, reduce demands on node operators, and prevent unnecessary blockchain expansion. Opponents say the proposal risks transforming a technical debate into a broader consensus issue by deciding which transactions should be considered valid.

The proposal has drawn criticism from several influential members of the Bitcoin community. Michael Saylor, founder of Strategy, argued that turning concerns about blockchain spam into a protocol-level dispute could create a larger threat than the original issue. He warned that changing rules around transactions that are currently valid and pay fees could set a problematic precedent.

Adam Back, Blockstream co-founder and creator of Hashcash, also voiced opposition. He said Bitcoin’s decentralized nature means changes cannot simply be imposed by a group of participants without wider agreement, suggesting that those who disagree with the current rules could create a separate network instead.

BIP 110 is taking a different path from traditional Bitcoin upgrades by relying on a user-activated soft fork model. Instead of requiring overwhelming miner approval, the proposal allows nodes running the software to enforce the new rules. It sets a miner signaling threshold of 55%, compared with the much higher levels used in previous soft forks.

However, miner support remains extremely weak. Signaling has never reached more than about 1% and currently stands at zero, with no major mining pools backing the proposal.

Adoption among nodes is also limited, remaining in the low single digits and largely coming from users running Bitcoin Knots, an alternative software implementation to Bitcoin Core.

The proposal’s timeline is continuing despite the lack of broad support. The current signaling period runs from block 957,600 to 959,615, followed by a voluntary lock-in deadline at block 961,542, expected in early August.

If BIP 110 moves forward, nodes running the software would begin rejecting blocks that do not follow the proposed rules, with activation expected around September. However, with minimal miner involvement and limited node adoption, the change would likely create a minority chain rather than become a network-wide upgrade.

Bitcoin’s governance model depends on voluntary participation from thousands of independent users, miners, and node operators. Protocol changes only succeed when enough of the ecosystem chooses to adopt them.

The discussion around BIP 110 highlights a larger philosophical divide within Bitcoin. Supporters believe limiting non-financial data is necessary to protect Bitcoin’s role as a decentralized monetary system, while critics argue that restricting valid transactions could undermine the network’s open and permissionless design.

For now, the proposal appears unlikely to gain the broad consensus required for a major Bitcoin upgrade, reinforcing the network’s cautious approach to protocol changes.
