Bitcoin Gold (BTG) is a cryptocurrency. It is a hard fork of Bitcoin, the open source cryptocurrency. It is an open source, decentralized digital currency without a central bank or intermediary that can be sent from user to user on the peer-to-peer Bitcoin Gold network.

The stated purpose of the hard fork is to change the proof of work algorithm so that application specific integrated circuits (ASIC) cannot be used to mine the Bitcoin Gold blockchain.[2]

Born as a community-driven project, it was initiated by Alejandro Regojo and Hang Ying as top developers.
