Bitcoin Gold was created in 2017 through a fork of the Bitcoin blockchain. It is a community-led project to create an experimental hard fork of Bitcoin to a new proof-of-work algorithm.

The Bitcoin Gold community initiated the fork as part of its mission to make Bitcoin mining decentralized again. The community claims that Satoshi Nakamoto’s idealistic vision of “one CPU one vote” has been superseded by a reality dominated by a very small number of entities, some of whom have allegedly engaged in abusive practices against individual miners and the Bitcoin network as a whole, such as influencing Bitcoin price.

The Bitcoin Gold blockchain contains the full transaction history of the Bitcoin blockchain up until the fork date, including the exact balances of Bitcoins held in wallets around the world, providing insights on Bitcoin price and other details about these wallets. Wallet addresses that contain Bitcoin immediately before the fork were given an equivalent amount of Bitcoin Gold immediately after the fork.

The Bitcoin and Bitcoin Gold blockchains both continue onward independently after the fork, with the Bitcoin Gold organization providing support for the latter. A crypto endowment held in multi-sig, time-locked wallets is funding current and future operations of the organization.

比特币黄金在区块491406(2017-10-24 01:17:35 utc)之后按计划分叉比特币区块链。BTG是对比特币区块链进行硬分叉得到的一种新的数字货币,具体时间为比特币区块高度491406(2017-10-24 01:17:35 utc),其主要特点为:

类似于bitcoin cash,BTG已经添加sighash_forked(一种硬分叉后的安全机制)。BTG将会采用equihash pow算法,这个算法和btc用的sha256的区别在于,哈希算力将受计算设备的内存大小影响。所以,asic矿机将不再有效用于BTG挖矿,这也是为了抵御asic导致的算力集中化,也算是给比特币未来能否修改挖矿算法做了一次实验路线猜想的实施。BTG目前存在的问题有:没有具名的代码开发者。同时,BTG代码库还包含8,000块(100,000 btg)的私有预挖区块。开发商可能会在公开市场上出售其预挖的BTG。
