Of course, the hottest thing is bitcoin. In addition to bitcoin, there are \x0d\ 1 and Litecoin \x0d\ similar to bitcoin. Litecoin is also encrypted in digital currency, and its price has risen sharply recently. It is an open source digital currency of P2P and can be regarded as a branch of Bitcoin. However, although Litecoin is based on the Bitcoin protocol, it does not require extremely high computing power, and it can be mined by ordinary computers. Litecoin's algorithm originated from the algorithm designed by Dr. Colin Percival for Tarsnap's secure online backup service (applicable to Linux and other open source operating systems). \x0d\2 and Namecoin\x0d\Namecoin are also based on bitcoin, which is another branch of open source. Namecoin is a distributed DNS protocol-in layman's terms, it can change a website name that humans can understand (such as ifeng.com) into an address that machines can understand. As its own DNS, this currency can run outside the normal internet, so it can escape the supervision of ICANN. The currency value and domain name of \x0d\Namecoin are stored in the user's blockchain record, which limits the total number to 265,438+0 million. \x0d\3, Peercoin\x0d\Peercoin are p2p variants of Bitcoin, which can improve the efficiency and security of mining and enhance safeguards to avoid group mining-now, group mining has been considered as a potential defect of Bitcoin. According to CoinMarketCap.com's statistics on emerging currencies, Peercoin currently ranks fourth in digital currency's market value. \x0d\4, Primecoin\x0d\Primecoin are cryptocurrencies similar to Bitcoin, but they use completely independent mining algorithms. Bitcoin uses Hashcash algorithm, while prime coins use long Cunningham chain to create the value of money-this is a prime sequence named after mathematician AJC Cunningham. \x0d\ In the process of bitcoin mining, the difficulty will increase sharply with the passage of money. However, prime numbers are different. Every time a Primecoin coin is excavated, the difficulty of excavation will increase slightly, and the process will be much smoother. \x0d\5, FeatherCoin \ x0d \ x0d \ FeatherCoin were designed according to Litecoin and released in April of 20 13, which can adjust the mining difficulty more frequently than Litecoin. Feathercoin will be updated frequently, adding new functions and improvements to prevent malicious mining. \x0d\\x0d\6, Novacoin\x0d\\x0d\ Another P2P digital cryptocurrency. Unlike most other currencies, Novacoin integrates a protection mechanism at the core of the currency to identify illegal mining activities. The total number of \ x0d \ x0d \ novacoin is limited to 2 billion pieces, which is quite impressive. If necessary, the total can be adjusted upwards. \ x0d \ x0d \ 7, Infinitecoin \ x0d \ x0d \ 2065438+was released in June 2003. By-product of Litecoin. According to the mining situation and the total amount of money, Infinite Coin can frequently adjust the mining difficulty ratio. \x0d\\x0d\8, mega coin \ x0d \ x0d \ 2065438+ was released in the fourth quarter of 2003, originally imitating bitcoin. The total number of Megacoin is limited to 42 million pieces, which can be mined like other virtual currencies. Its biggest selling point is brand promotion, which is exactly what other digital currency lacks. \x0d\\x0d\9, Quarkcoin \ x0d \ x0d \ 20 13, still in the initial stage. In the security part of the quark coin, nine independent encryption loops are deployed and six different algorithms are adopted.
