A blockchain fork connected to the BIP-110 proposal has fallen 18 blocks behind Bitcoin’s primary chain, Bitcoin.com News reported. The gap points to a sharp disparity in mining power between the two competing versions of the ledger.
Bitcoin Improvement Proposals, or BIPs, are formal documents used to suggest changes to the network’s rules. Most proposals are debated for months or years before developers, miners, and node operators reach rough consensus. When that consensus fails to materialize, a portion of the network can choose to enforce new rules anyway, creating a split commonly known as a fork.
Forks come in different forms. Some are coordinated upgrades that the vast majority of the network adopts without disruption. Others are contentious, producing two separate chains that share a common history but diverge going forward. The BIP-110 fork described in the report appears to fall into the latter category, based on the language used to characterize it as splintered.
In Bitcoin’s design, the chain with the greatest cumulative proof-of-work is treated by software clients as the valid, authoritative record. A chain that falls behind in block count is, by definition, attracting less mining activity. That typically means fewer machines are dedicating computing power to extend it. An 18-block deficit is a meaningful signal in this context, since it indicates a sustained pattern rather than a brief statistical fluctuation.
History offers several precedents for how these situations tend to unfold. Past Bitcoin-related splits, including the 2017 divergence that produced Bitcoin Cash, showed that minority chains can persist independently if enough participants continue supporting them economically. Other proposed forks, such as the abandoned SegWit2x effort, collapsed before ever launching because support evaporated. Falling behind in block production does not guarantee a chain’s failure, but it does weaken its security. Chains with less accumulated work are generally more vulnerable to reorganization attacks and are viewed with more caution by exchanges and custodians deciding whether to list or support the asset.
The report does not specify the exact technical changes BIP-110 proposes, nor does it detail which mining pools or node operators are backing the minority chain. Without that information, it remains unclear whether the fork represents a serious ideological challenge to Bitcoin’s existing rule set or a smaller, more marginal effort. What is documented is the block gap itself, which offers a rough proxy for relative support at this stage.
Market participants tracking contentious forks typically watch several signals beyond block count. These include the number of full nodes running the alternative software, whether exchanges list a separate ticker for the forked asset, and whether any mining pools publicly commit hash power to the new chain. None of those additional data points were included in the current report.
Sources disagree on this story
This article was published before the reports below were compared. The reporting above stands; what follows is where the published accounts do not agree.
Bitcoin.com News and CoinDesk both report a BIP-110 chain split stalling far behind Bitcoin's main chain, but disagree on which pool produced the minority chain's second block and on how many blocks separate the two chains.
What all sources agree on
- Bitcoin's chain split occurred at block height 961632 over the BIP-110 proposal.
- The BIP-110 minority chain has stalled, producing far fewer blocks than the main chain.
- The minority chain inherited the main chain's mining difficulty despite having only a small fraction of its hashpower.
- Only 2.53% of recent blocks signalled support for BIP-110.
Where the reports disagree
1Which miner/pool produced the minority chain's second block (961633)
Roughnecks mined BIP-110 blocks 961632 and 961633 as Bitcoin’s dominant chain raced ahead.
Bitcoin mining firm AntPool mined the first non-signalling block, which the rest of the network accepted and BIP-110 nodes rejected, and a miner using Ocean produced the alternative that the breakaway chain followed instead.
What would settle it: On-chain block data showing the coinbase/pool signature of block 961633 on the minority chain.
2Size of the gap between the main chain and the minority chain
Bitcoin's Splintered BIP-110 Fork Falls Behind by 18 Blocks
the main bitcoin chain has reached block 961,681 … A block is a batch of transactions added to bitcoin's ledger roughly every ten minutes, so the gap of 48 represents most of a day's worth of activity on one side and almost none on the other.
What would settle it: The blockchain's own height at a specified timestamp, which would explain the gap difference if the reports were published at different times; not otherwise resolvable from these two reports alone.
What to make of it
Treat the chain split at block 961632 and the minority chain's stall as established; do not treat the identity of the second block's miner, or the exact block-gap figure, as settled until confirmed against on-chain data.
Market Impact
A widening block gap on a minority chain usually signals limited miner conviction, which can translate into thin liquidity and higher volatility if the forked asset trades separately from Bitcoin. Exchanges tend to move cautiously before listing assets from contested splits, wary of replay attacks or future chain instability.
For the broader Bitcoin market, a fork falling behind by double-digit blocks is unlikely to affect the primary chain's price action directly, since the dominant chain retains the overwhelming share of hash power. Investors holding Bitcoin are not typically exposed to risk from a lagging fork unless they choose to interact with the minority chain's tokens or infrastructure.
The 18-block gap underscores how quickly minority chains can lose ground once mining support concentrates elsewhere. Further reporting will be needed to clarify what BIP-110 actually proposes and whether its fork can sustain independent activity going forward.
Frequently Asked Questions
What is BIP-110?
BIP stands for Bitcoin Improvement Proposal, a formal document outlining a suggested change to Bitcoin's protocol. The specific technical content of BIP-110 was not detailed in available reporting.
What does it mean for a fork to fall behind by 18 blocks?
It means the splinter chain has produced 18 fewer blocks than Bitcoin's main chain since the split, indicating it has attracted significantly less mining power.
Does this affect the price or security of Bitcoin itself?
The main Bitcoin chain retains the dominant share of network hash power, so a lagging minority fork is not expected to directly impact Bitcoin's own price or security.
Could the BIP-110 fork still survive despite falling behind?
Past forks have shown that minority chains can persist if enough users and exchanges continue supporting them, though a growing block deficit generally signals weaker security and lower confidence.
