BIP-110 forks have a risk of replay attacks, selling forked coins or spending real bitcoins

Bitcoin developer Kevin Loaec warned that if a Bitcoin fork related to the controversial proposal BIP-110 occurs this weekend, holders may face the risk of real BTC being transferred when selling forked chain tokens.

The proposed Bitcoin fork is associated with the controversial BIP-110 proposal and may generate duplicate balances on two chains, leading holders to attempt to sell seemingly free forked coins.

Since both chains initially accept the same transactions, selling forked coins could trigger a replay attack, simultaneously spending real Bitcoin from the seller's main chain. Developers stated that there is a lack of built-in replay protection at least until early September, and non-professional users should avoid transferring Bitcoin during the potential fork.
