Bitcoin Gold Daily Update – Replay Protection fully implemented
Nov 1, 2017 | Development
In order to ensure the safety of the Bitcoin ecosystem, Bitcoin Gold has implemented full replay protection, an essential feature that protects users’ coins from being spent unintentionally.
Bitcoin Gold has just implemented a solution called SIGHASH_FORK_ID replay protection. It is an effective two-way replay protection mechanism that enforces a new algorithm to calculate the hash of a transaction so that all new Bitcoin transactions will be invalid on Bitcoin Gold blockchain and vice versa. This makes replaying transactions impossible.
