Bitcoin, once close to 4.6 million times higher, was called "digital gold" by investors. So far, the total market value of bitcoin has exceeded 374.8 billion yuan. Bitcoin is favored by technology lovers because of its decentralization, global circulation, low transaction cost and anonymous circulation. Recently, traditional financial institutions such as Wall Street and central banks of many countries have begun to study the technology of bitcoin blockchain, and the people's Bank of China has also announced plans to develop Digital Currency.

Bitcoin cash is the same as bitcoin. It is a cryptocurrency based on decentralization, point-to-point network and consensus initiative, open source code, and blockchain as the underlying technology. The bitcoin community has been arguing about the issue of capacity expansion for three years. Finally, on August 1, 2017, bitcoin cash was hard forked at block height of 478558, distributed according to bitcoin 1:1, with a total amount of 21 million, deleted the isolation witness, upgraded the block upper limit to 8m, and then upgraded to 32m. Through the capacity expansion on the chain, the problems of high handling fees, slow confirmation, and poor practicability in the old bitcoin system were solved. To fulfill bitcoin's commitment as "point-to-point e-cash".

Litecoin is a kind of network currency based on "peer-to-peer" technology, which is inspired by BTC and has the same implementation principle in technology. It is different from bitcoin in that it can also "mine" efficiently through consumption level hardware, providing faster transaction confirmation (average 2.5 minutes). Litecoin network is expected to produce 84 million currency units.
EOS is a blockchain architecture platform similar to the operating system developed under the leadership of blockchain wizard BM (Daniel Larimer), aiming to achieve performance expansion of distributed applications. EOS provides account, authentication, database, asynchronous communication and program scheduling on hundreds of CPUs or clusters. The ultimate form of the technology is a blockchain architecture, which can support millions of transactions per second, and ordinary users do not need to pay for the use of the fee.
8. TRX-wave coins
Wave field Tron is committed to promoting the decentralization of the Internet and building infrastructure for the decentralized Internet. Its Tron protocol is one of the largest blockchain based decentralized application operating system protocols in the world. It provides high throughput, high expansion and high reliability public chain support for the decentralized application operation on the protocol. Wave field Tron also provides better compatibility for Ethereum smart contract through innovative pluggable smart contract platform.
Dogecoin, some people call it "dogcoin / dogcoin", was born on December 8, 2013. Based on the crypt algorithm, dogecoin is the second largest virtual currency after bitcoin in the number of users in the world. After the dogcoin system went online, thanks to the help of reddit (the doge content on this website overflows horribly), the traffic shows explosive development. However, in two weeks, dogcoin has spread out special blogs and forums, with a market value of 100 million as of June 9, 2015. Due to the lack of pre excavation, dog money distribution is fair, charity and reward culture are popular, and users develop rapidly. On June 9, 2015, the number of bitcoin client addresses was 1.6 million, more than 5 times that of litecoin; the number of active client addresses was 196000, 83000 and 11000 bitcoin; the number of foreign Twitter users was 150000, 1.7 times that of bitcoin, 6 times that of litecoin; Facebook's likes were the same as that of bitcoin, far more than that of litecoin. The daily real trading volume has been ranked in the top three of virtual currency for a long time, which is still not achieved before the big platform. The biggest value in the era of enterprise Internet is the huge number of users. In one year, the user base of dogcoin has reached one-third of the number of bitcoin users and four times of litecoin users.
10. VDS- Volar
V-dimension, referred to as VDS for short, is a blockchain public chain project launched on February 14, 2019, and the project party is anonymous. Based on the blockchain technology and the design principle of decentralized anonymity, VDS constructs a "private Internet" on distributed nodes for all the public to use.
VDS embeds many initial functions in the cryptocurrency wallet, among which "resonance transaction" and "trust stamp" are widely discussed in the blockchain world. "Resonance transaction" is the channel for bitcoin to exchange vollar (the name of the standard currency unit in VDS) one way, "Trust Seal" is a interpersonal network established based on the identity sign vid (a special transaction address) in the VDS ecosystem. In addition, the initial functions of VDS include bitcoin competition, lucky draw, information broadcast, privacy chat, anonymous transaction, smart contract, distributed OTC transaction, super master node, chain merchant contract, etc.
