Bitcoin Proposal to Temporarily Limit Data Storage Nears August Deadline With No Miner Support
BIP-110 would temporarily cap non-financial data on the Bitcoin blockchain for one year through tighter OP_RETURN limits and other restrictions. Miner signaling stands at zero and node adoption remains in the low single digits. Michael Saylor and Adam Back have publicly opposed the measure.

A proposal to temporarily restrict non-financial data on the Bitcoin blockchain is approaching a voluntary lock-in deadline at block 961,542, expected in early August 2026, with miner signaling at zero. CoinDesk reported that BIP-110, formally titled the Reduced Data Temporary Soft Fork, would cap OP_RETURN at its previous small size, block most arbitrary data chunks above 256 bytes, and restrict some script formats used mainly for data storage for one year.
The measure uses a user-activated soft fork mechanism with a 55% miner-signaling threshold rather than the traditional 95%.
The current signaling period runs from block 957,600 to 959,615. Activation is projected near September 2026 if the threshold is met. Michael Saylor posted on July 11, 2026, that there are 110 things more dangerous to Bitcoin than spam and that BIP-110 turns a spam dispute into a consensus change that would invalidate some currently valid, fee-paying transactions.
Adam Back stated that Bitcoin respectfully says no to what the BIP-110 backers want and that their recourse is to fork away. Blocks have carried more non-financial data since an October change. No major mining pool is signaling support for BIP-110, and node adoption of the software sits in the low single digits, carried almost entirely by Bitcoin Knots, according to CoinDesk.
In practice, a rule enforced by a few percent of nodes and almost no miners would not change Bitcoin for everyone but would split off a minority chain.
