BTG Bitcoin Gold is one of the forked coins of Bitcoin. It is a new currency that was split from Bitcoin at block height 491407 on October 24, 2017.
According to the BitcoinGold website (http://btcgpu.org/), at the preset block height of 491407, BTG miners used a new proof-of-work (PoW) algorithm to create blocks, which resulted in A fork in the Bitcoin blockchain. As a result of this process, a new virtual currency was born, which is now BTG.
BTG (Bitcoin Gold) was proposed by Liao Xiang, CEO of mining hardware manufacturer Lightning ASIC, and was officially announced on Bitcointalk.org at the end of July 2017. Unlike BCC and Segwit2X, its goal is to return mining to CPUs and GPUs by changing the proof-of-work algorithm, thereby solving the increasingly prominent problem of Bitcoin mining centralization.
With other forks Compared with other currencies, BTG did not expand the capacity of BTC, but still used the 1M block + SegWit setting. The main change was the mining algorithm in order to prevent the over-concentration of computing power caused by ASIC dedicated mining machines. Restrictions. BTG switches to GPU mining and uses the scheduling adjustment mechanism EDA. The hottest one is of course Bitcoin. In addition to Bitcoin, there are: \x0d\x0a1, Litecoin\x0d\x0a Similar to Bitcoin, Litecoin is also an encrypted digital currency, and its price has risen sharply recently. It is a P2P open source digital currency and can be regarded as a branch of Bitcoin. However, although Litecoin is based on the Bitcoin protocol, it is not. It requires extremely high computing power and can be mined using ordinary computers. The algorithm of Litecoin is derived from the algorithm designed by Dr. Colin Percival for the Tarsnap secure online backup service (for Linux and other open source operating systems backup) \x0d\x0a2. Namecoin\x0d\x0aNamecoin is also based on Bitcoin and is considered another open source branch. Namecoin is a distributed DNS protocol-in layman's terms, it can convert human-understandable website names (such as ifeng.com) into an address that the machine can understand. As its own DNS, this currency can operate outside the normal Internet, so it can be stored outside the control of ICANN\x0d\x0aNamecoin's blockchain record. , limiting the total number to 21 million \x0d\x0a3, Peercoin\x0d\x0aPeercoin is a p2p variant of Bitcoin that can improve mining efficiency, security, and improve safeguards to avoid group mining-now , Group mining has been considered a potential flaw of Bitcoin. According to CoinMarketCap.com's statistics on emerging currencies, Peercoin currently ranks fourth in the market value of digital currencies. Primecoin is similar. Bitcoin is a cryptocurrency, but it uses a completely independent mining algorithm. Bitcoin uses the Hashcash algorithm, while Prime uses long Cunningham chains to create the value of the currency. The prime number sequence named by mathematician AJC Cunningham. \x0d\x0a During the Bitcoin mining process, the difficulty will increase sharply as the amount of money increases, but Prime is different. Every time a Primecoin coin is mined, the mining difficulty will decrease slightly. With increases, the process is much smoother. \x0d\x0a5, Feathercoin\x0d\x0a\x0d\x0aFeathercoin is designed based on Litecoin and was released in April 2013. It can adjust the mining difficulty more frequently than Litecoin. Feathercoin will be updated frequently to add new features and improvements to prevent malicious mining activities. \x0d\x0a\x0d\x0a6, Novacoin\x0d\x0a\x0d\x0aAnother P2P digital cryptocurrency. What makes Novacoin different from most other currencies is that it integrates a protection mechanism at the core of the currency to identify illegal mining behavior. \x0d\x0a\x0d\x0aThe total number of Novacoins is limited to 2 billion, which is a considerable amount. The total can be adjusted upwards if needed. \x0d\x0a\x0d\x0a7, Infinitecoin\x0d\x0a\x0d\x0aReleased in June 2013. A by-product of Litecoin. Infinite Coin can have frequent mining difficulty ratio adjustments based on mining conditions and total currency count. \x0d\x0a\x0d\x0a8 and Megacoin\x0d\x0a\x0d\x0a were only released in the fourth quarter of 2013 and initially imitated Bitcoin. The total number of Megacoins is limited to 42 million and can be mined like other virtual currencies. Its biggest selling point is brand disclosure, which is something other digital currencies lack. \x0d\x0a\x0d\x0a9 and Quarkcoin\x0d\x0a\x0d\x0a were released in 2013 and are still in their early stages. The security part of Quarkcoin deploys 9 independent loops of encryption and uses 6 different algorithms.
