Huoxing Finance reports that on August 9, the Bitcoin network experienced a fork due to BIP-110. Nodes supporting the proposal rejected blocks at block height 961,632 that did not include a support signal. As of now, the main Bitcoin chain has progressed to block 961,651, while the BIP-110 fork chain has only reached block 961,633, lagging 18 blocks behind. BIP-110 is a one-year rule adjustment proposal aimed at limiting the inclusion of non-financial data in Bitcoin transactions, including uses such as Ordinals inscriptions. The proposal required at least 1,109 blocks (55%) to signal support within a two-week period of 2,016 blocks to activate; however, in the previous period, only 51 blocks supported it, representing 2.53%. Currently, the BIP-110 chain still needs additional miner support to continue. According to the rules, the chain must reach block 963,648 to lock in the rules and will begin enforcing restrictions starting at block 965,664, lasting approximately one year. Previously, Bitcoin developer Kevin Loaec warned that if a Bitcoin fork related to the controversial BIP-110 proposal occurs this weekend, holders selling tokens on the forked chain may face the risk of their actual BTC being transferred away.
