BIP-110 Fork Looms: Bitcoin Holders at Risk of Replay Attacks

A potential Bitcoin fork, enabled by BIP-110, could expose holders to replay attacks if they try to sell coins created on the new chain without first separating their balances. According to Bitcoin developer Kevin Loaec, moving these coins could result in a loss of real BTC.

The proposed fork, which seeks to restrict non-payment data stored through transactions for about one year, has not reached the necessary 55% threshold of miner support. Despite this, some miners have begun signaling their support, with around 2.6% currently backing the proposal.

Loaec warned that holders who do not know how to separate their balances can avoid the risk by leaving their coins unmoved until wallets and exchanges clarify which chain they support.
