Developer Warns Accidental Bitcoin Sales Possible via BIP-110 Replay Risk

A developer has highlighted a BIP-110 flaw that can cause users to lose real BTC when trying to sell fork tokens, recommending that holders avoid transacting entirely.

BTC

A Bitcoin holder recently attempted to sell tokens received from a fork, mistakenly selling actual bitcoins instead. The incident illustrates a known risk associated with BIP-110, according to developer Kevin Loak.

Loak warned that transactions initiated on a forked chain can be replayed on the main Bitcoin network if the same private key controls both addresses. Since BIP-110 provides no protection against such replay attacks, a user might unintentionally authorize a BTC transfer when they only intended to move fork tokens.

“The safest strategy is to do nothing at all,” Loak advised. He cautioned that even attempting to separate or sell free coins could lead to the loss of real bitcoin, urging extreme caution until better safeguards emerge.
