Bitcoin Gold will implement 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 the new Bitcoin transactions will be invalid in Bitcoin Gold blockchain and vice versa. Bitcoin Gold is a hard fork of BTC which took place at block , on 24 October This sighash algorithm is only used when the sighash flag has bit 6 set. These transactions would be invalid on the non-UAHF chain as the different sighashing algorithm will result in invalid transactions. Nov 28, · The current, ASIC-driven Bitcoin Blockchain uses a hashing algorithm known as SHA for its proof of work. The founders of Bitcoin Gold instead use another algorithm known as gasthausamflughafen.de Biryukov and Dmitry Khovratovich developed Equihash as an ASIC-resistant algorithm, and it has already seen success powering other cryptocurrencies, the most famous of which is Zcash.

Bitcoin Gold started as a fork of Bitcoin after block height on October 24, and started being mined as a separate chain at block height on November 12, The primary goal of this fork is to maintain a variant of Bitcoin that is more decentralized by using an ASIC-resistant Proof of Work algorithm, removing barriers to entry for new miners around the world and reducing the concentration of power in the brands of huge-scale mining operations.
Major differences at launch time included —. Although Bitcoin Gold was bootstrapped for creating an entirely new network, yet it contains the complete Bitcoin blockchain until block Ultimately, Bitcoin Gold became a full fork with all Bitcoin transaction history since His passion for doing friendship with words and letting people know about the wonders of the Digital World is what motivates him to take writing as a career.

The argument Bitcoin Gold wants to make is to make mining Bitcoin something everyone can do, therefore keeping the mining as decentralized as possible. The fundamental change in Bitcoin Gold is choosing a different hashing algorithm that makes proof of work more difficult for ASICs.
This is accomplished when a hashing algorithm requires more memory RAM to complete. Since ASICs are about pure processing power, requiring more memory bottlenecks their processing ability. This makes small-time mining on GPUs competitive once again. Next, download the mining software from the pool that you joined. The Bitcoin Gold hard fork occurred on October 24, , with block , on the Bitcoin Blockchain. When that happened, Bitcoin Gold took a snapshot of all the balances and transactions on Bitcoin up to that point.
The new Blockchain began from there. Mining on such networks comes in the form of smaller-scale GPU mining. The problem for Bitcoin Gold is those other anti-ASIC cryptocurrencies have a longer history and are more predictable for miners. The one advantage that Bitcoin Gold has is wide dispersal. With so many forks on the Bitcoin Blockchain in such quick succession, it can be confusing to keep track of the differences.
