BIP-110 fork carries replay attack risk; selling fork coins could spend real Bitcoin

Odaily News: The proposed Bitcoin fork is associated with the controversial BIP-110 proposal and could generate duplicate balances on both chains, potentially prompting holders to attempt selling seemingly free fork coins. Since both chains initially accept the same transactions, selling fork coins could trigger a replay attack and simultaneously spend the seller's real Bitcoin on the main chain. Developers have stated that built-in replay protection will be lacking at least until early September, and non-professional users should avoid transferring Bitcoin during the potential fork period.
