Ledger warns BIP-110 fork lacks replay protection, recommends not claiming forked coins for now

TechFlow news, August 09, hardware wallet vendor Ledger issued a security alert regarding the BIP-110 fork, stating that BIP-110 is a Bitcoin soft fork proposal without built-in replay protection. If an independent chain is formed, BTC holders may receive an equivalent amount of corresponding assets on the new chain, but both chains may initially accept the same signed transactions. If users attempt to transfer or sell assets on the BIP-110 chain, relevant transactions may be "replayed" to the Bitcoin main chain, causing the corresponding BTC to be transferred out simultaneously.

Ledger stated that its devices are technically capable of signing relevant transactions, but advised against claiming or operating BIP-110 forked coins before the replay protection mechanism is implemented.
