Bitcoin Gold (BTG)

Bitcoin Gold (BTG) is a blockchain that resulted from hard forking Bitcoin's blockchain on October 24th, 2017. The hard fork took place at block height 419,407. The Bitcoin Gold team aimed at restoring the mining functionality with GPUs, as bitcoin mining had been rendered almost impossible with GPUs and CPUs. ASIC miners became the only hardware capable of mining the world's first-ever cryptocurrency. The hard fork was created by a process that involved the mining of around 8,000 blocks at a high speed that led to the creation of 12.5 BTG coins per block. Bitcoin Gold's blockchain utilizes a unique proof-of-work (PoW) algorithm known as Equihash, instead of Bitcoin's SHA256 algorithm.
