Bitcoin Gold is an experimental Bitcoin hard fork that prioritizes "one CPU one vote" blockchain governance. Bitcoin Gold forked from Bitcoin at block 491407. This fork implements a new proof-of-work (PoW) algorithm to replace SHA256, namely Equihash, to achiee "ASIC resistance", a point of criticism for status quo Bitcoin mining. In the white paper, Bitcoin Gold explains its readiness to hard fork if or when Equihash is vulnerable to ASIC miners. Also, Bitcoin Gold's difficulty adjustment algorithm (DAA) is different: DigiShield V3. This change is intended to protect the network from abnormal changes in difficulty from significant changes in total hash power. Instead of launching immediately after the "snapshot" of the original chain and crediting equal balances of the fork coins to original addresses, Bitcoin Gold officially launched a few days after the chain split.
