Bitcoin splits over BIP-110 proposal, fork chain trails main network by 18 blocks

Bitcoin saw another chain split on Aug. 9 after nodes backing BIP-110 began rejecting blocks that did not carry support signals at height 961,632. At the time of the update, Bitcoin’s main chain had advanced to block 961,651, while the BIP-110 fork chain had only reached 961,633, leaving it 18 blocks behind. BIP-110 is a one-year rule change proposal aimed at limiting non-financial data written into Bitcoin transactions, including uses such as Ordinals inscriptions. Under the proposal, activation requires at least 1,109 signaling blocks, or 55%, within a 2,016-block period of roughly two weeks. In the prior signaling window, however, only 51 blocks supported the proposal, equal to 2.53%. The fork chain still needs more miner backing to keep moving forward. Under the stated rules, it would need to reach block 963,648 to lock in the change, and the restrictions would begin at block 965,664 for about one year. BlockBeats also cited an earlier warning from Bitcoin developer Kevin Loaec, who said holders selling fork-chain tokens this weekend could face a risk that real BTC might be transferred away.

Developer warns BIP-110 fork could expose Bitcoin holders to replay theft

Bitcoin developer Kevin Loaec warned on Aug. 8 that if a Bitcoin fork tied to the disputed BIP-110 proposal emerges this weekend, holders trying to sell coins on the forked chain could accidentally lose real BTC on the original network. The risk comes from the lack of replay protection in the early stage of a chain split, which could allow a transaction signed on one chain to be copied and executed on the other. According to the report, if Bitcoin splits into two chains, users may initially hold matching BTC balances on both. That may tempt some traders to sell what looks like “free” fork coins. But without proper separation of assets, the signed transaction used to move those fork coins could also be valid on the main Bitcoin chain, letting the buyer receive the same amount of real BTC. Loaec said the safest option for holders who do not know how to securely split assets across both chains is to do nothing for now. He added that untouched BTC is not exposed to replay attacks because no signed transaction exists to copy. BIP-110 currently has about 2.6% miner signaling support, far below the level needed for activation, leaving uncertainty over whether a fork will actually take shape.

Bitcoin Developer Warns of Replay Attack Risk in Potential BIP-110 Fork

Bitcoin developer Kevin Loaec has issued a warning about a possible bitcoin fork connected to the controversial proposal BIP-110. If the fork happens this weekend, holders who sell the resulting forked-chain tokens may face the risk of having their real BTC stolen. The proposed fork could lead to duplicate balances existing on both chains. This might tempt holders to sell what appear to be free forked coins. However, during the initial phase, both chains accept the same set of transactions. As a result, selling forked coins could trigger a replay attack, where the seller's genuine bitcoin on the main chain is spent at the same time. The developer stated that there is no built-in replay protection, at least until early September. Therefore, non-professional users should avoid moving bitcoin during the potential fork. This warning highlights the danger of interacting with forked assets without proper safeguards.
