TheBlock
A small group of nodes supporting BIP-110 broke from Bitcoin’s main network at block 961,632. By 6:00 p.m. ET, their chain had produced only 2 new blocks and was 7 blocks behind, while Bitcoin’s main blockchain continued adding blocks normally. The fork was supported by only a fraction of the main network’s mining power.
Why it matters
BIP-110 is a one-year proposal to limit non-financial data, including Ordinals inscriptions, making the split a dispute over how Bitcoin block space is used. Only 2.53% of blocks signaled support over the last two weeks, well below the 55% threshold needed to lock in the proposal without a split.
The early block gap shows how mining power can determine which branch leads after a contentious change. BIP-110 supporters are operating on a minority chain rather than changing the rules of Bitcoin’s main network.
Market impact
The market signal is governance uncertainty around Bitcoin’s block-space policy. The main chain’s normal block production gives miners and node operators a visible comparison with the fork.
The key markers are future signaling, the fork’s share of mining power and whether the 7-block gap widens or narrows. For now, Bitcoin’s main network remains the dominant branch.
Frequently asked questions
-
What does BIP-110 propose for Bitcoin block space?
It is a one-year proposal to limit non-financial data, including Ordinals inscriptions, on Bitcoin. The proposal has sparked debate over how block space should be used.
-
How much support did BIP-110 have before the chain split?
Only 2.53% of blocks signaled support over the last two weeks, below the 55% threshold needed to lock in the proposal without a split.
-
What happened to Bitcoin’s main chain after the fork?
Bitcoin’s main blockchain continued adding blocks normally, while the BIP-110 chain produced only 2 new blocks and fell 7 blocks behind by 6:00 p.m. ET.
-
Why does mining power matter in the BIP-110 split?
The fork had only a fraction of the main network’s mining power, while Bitcoin’s main chain continued producing blocks normally. That imbalance left the BIP-110 branch behind.
-
Which indicators will show whether the BIP-110 fork gains traction?
Future signaling, the fork’s share of mining power and whether the 7-block gap widens or narrows are the key markers.
