Bitcoin holders could face replay-attack risk if the controversial BIP-110 proposal produces a minority chain split around block 961,632 this weekend. Miner signaling was about 2.6% on Friday, far below the 1,109-of-2,016 blocks, or 55%, needed for activation, yet nodes enforcing BIP-110 would still reject non-signaling blocks, potentially leaving duplicate balances on two chains. Bitcoin developer Kevin Loaec had warned that a transaction used to claim, sell or move the forked coins could also be replayed on Bitcoin's main chain and transfer the same amount of real BTC, with fees paid on both chains. Ledger has now issued a similar security alert, saying its hardware wallets can technically sign such transactions but advising users not to claim or interact with any BIP-110 forked assets until replay protection is added.
