According to CoinDesk, Kevin Loaec, a Bitcoin developer and CEO of Wizardsardine, warned that if a BTC fork occurs due to the BIP-110 proposal, there is a risk of 'replay attacks' where actual BTC could also be transferred when selling coins on the forked chain. Immediately after a fork, both chains recognize the same transaction signatures, and because automatic Replay Protection is not applied, if a third party submits a transaction signed by a user to sell coins on the forked chain to the mainnet, the same amount of actual BTC could also be transferred on the mainnet. In this regard, he added, "For general investors who do not know how to safely split assets on the two chains, it is safest not to conduct any on-chain transactions during the fork period." BIP-110 is a proposal that restricts the inclusion of payment-unrelated data such as images and text in Bitcoin transactions. For activation, it requires support from over 55% (1,109 blocks) of miners out of the most recent 2,016 blocks, but the current miner support rate is only about 2.6%, indicating a de facto failure to reach consensus. However, despite this, BIP-110 is designed such that BIP-110 nodes will automatically reject blocks without the relevant signal starting from block height 961,632 (expected this weekend), raising the possibility that the Bitcoin chain could split into two if some nodes maintain a separate chain.
