Saylor Calls BIP-110 Bitcoin Fork Dead at 2.7% Miner Support

Saylor pointed to live signaling data. At block height 961,022, only 38 blocks had signaled for BIP-110, or about 2.70% of the current period. So the 55% voluntary threshold is now out of reach before the window closes.

What BIP-110 Proposes

The BIP-110 Bitcoin Fork is formally titled the “Reduced Data Temporary Softfork” and previously circulated as BIP-444. The pseudonymous developer Dathon Ohm authored the proposal, while Luke Dashjr contributed to its original draft and technical direction.

The proposal introduces seven stricter consensus rules designed to limit arbitrary data embedding. These rules target Ordinals inscriptions, large OP_RETURN payloads, BRC-20 and Runes-style tokens, and certain Taproot constructions used for similar purposes.

Standard monetary transactions remain unaffected. Common payment types such as P2PKH, key-path Taproot, and Lightning would continue working normally. The network permanently grandfathers pre-activation coins, while the new restrictions expire automatically after roughly one year.

You can read the full rule set in the BIP text on GitHub, which reached “Complete” status on June 25. The team also maintains a proposal site at bip110.org.

How the BIP-110 Activation Works

BIP-110 uses a modified BIP-9 deployment on version bit 4. Miners signal readiness by setting that bit in the blocks they mine. Because the change is temporary, the proposal lowers the usual bar from 95% to 55%.

Early voluntary lock-in needs 1,109 of 2,016 blocks in a single difficulty period. So far no period has come close. Signaling has stayed near or below 3%, and it sits concentrated in Ocean and small independent miners.

The current period runs from block 959,616 to 961,631. When that period ends, a mandatory window opens from block 961,632 to 963,647. During that window, upgraded nodes reject any block that does not signal for BIP-110.

If enforcement holds, lock-in follows no later than block 963,648, and activation lands at block 965,664. That projects to early September 2026, based on average ten-minute blocks.

Why Saylor Says BIP-110 Should Stand Down

Saylor’s math is straightforward. Too few blocks remain in the period to reach 1,109 signals, so voluntary lock-in cannot happen this round. Meanwhile major pools like Foundry, Antpool, and ViaBTC have not committed to signal.

“Unless major miners reverse, Bitcoin continues normally while BIP-110 stalls or forks into irrelevance,” Saylor wrote in his post on X. “Its backers should stand down.”

Other critics echo the concern. Adam Back of Blockstream called the parameters reckless and technically flawed. Jameson Lopp of Casa also labeled the design “doomed to fail.” In a detailed critique, he warned of a chain split.

Supporters Say BIP-110 Still Activates

Backers reject the stand-down framing around the BIP-110 Bitcoin Fork. Because upgraded nodes decide which blocks are valid, they argue miners do not have the final say. In their view, the mandatory signaling window forces the issue regardless of current hashrate support.

Dathon Ohm and other supporters insist activation will proceed. Enforcement runs mainly through Bitcoin Knots, the node software that includes the stricter consensus rules. Supporters therefore point to node adoption, rather than miner signaling alone, as the more important measure.

They also cite historical precedent. The 2017 BIP-148 user-activated soft fork helped push SegWit forward despite slow miner support. As a result, BIP-110 supporters view node enforcement as a proven activation path rather than an empty threat.

The Chain-Split Risk in BIP-110

The BIP-110 Bitcoin Fork carries a significant technical risk. At block 961,632, BIP-110 nodes begin rejecting non-signaling blocks. If most hashrate continues mining under the existing rules, enforcing nodes could follow a slower minority chain.

A minority chain would face longer block times and weaker security. Meanwhile, exchanges, custodians, and wallets generally follow the chain with the most accumulated work and deepest liquidity. As a result, a minority fork could gradually become economically irrelevant.

Markets have remained calm throughout the debate. Bitcoin traded between roughly $63,500 and $64,200 around August 4, with no clear spike or crash linked to Saylor’s post. Traders therefore appear to be pricing in network continuity rather than a lasting chain split.

What Comes Next for BIP-110

The next hard checkpoint for the BIP-110 Bitcoin Fork arrives quickly. Block 961,632 is projected for August 7–9 and will open the mandatory rejection window. The coming days should therefore reveal whether any major mining pool reverses course and begins signaling.

Several questions stay open. It is unclear whether backers will abandon the effort, persist on a minority chain, or soft-fork further. It is also unclear how many nodes will actually enforce the rules once the window begins.

For now, readers can track the count directly on the official signaling monitor and independent trackers. As the window nears block 961,632, those figures will move quickly, so re-checking the live data matters.
