Bitcoin is a worldwide cryptocurrency, and digital payment system called the first decentralized digital currency since the system works without a central repository or single administrator. It was invented by an unknown programmer, or a group of programmers, under the name Satoshi Nakamoto and released as open-source software in 2009. The system is peer-to-peer, and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes and recorded in public distributed ledger called a blockchain.
Bitcoin Cash is a hard fork of the cryptocurrency bitcoin. The fork occurred on August 1, 2017.
Bitcoin Diamond (BCD) is a new digital currency which is developed by an overseas group Evey and 007 group together. Bitcoin Diamond is a fork of Bitcoin that occurs at the predetermined height of block 495866 and therewith a new chain will be generated as the BCD. The total amount of BCD is 210 million. No more increase. 170 million BCD, 1BTC: 10BCD will be presented to the Bitcoin holders for the long-term Bitcoin ECOSYSTEM support. The rest 40 million will be automatically transferred into the community rewards pool as tributes and mining. Bitcoin Diamond Foundation will take it in charge, the official web is: http://www.btcd.io
Releasing time: block height 498888 Total supply: 21,210,000
Super Bitcoin team announces that they schedule to fork the blockchain at the height of 498888, which is embedded smart contract, and expanded the block size to 8 MB. Their team plans to launch embed smart contract and improved scalability of BTC features on Mar. 1, 2018; on May 31 to launch incorporated zero-knowledge proof feature; on Dec. 30, 2018, to launch the removed dynamic checkpoint protection feature. SBTC will have a total supply of 21,210,000, of which 210,000 will be pre-mined, and the pre-mind coins will be taken in charge by the foundation, most are used for motivating their developers, investing in eco-system and for the foundation operation.
Listing time: 2017/07/10 Total supply: 1,000,000,000
EOS（Chinese name: EOS, English name: EOS，Abbreviation:
EOS is a new blockchain architecture developed by Blockone company. It is a blockchain-based, decentralized operating system, designed to support commercial-scale decentralized applications by providing all of the necessary core functionality, enabling businesses to build blockchain applications in a way similar to web-based applications.
EOS’s asynchronous communication and parallel processing provide scalability, while its ownership model eliminates transaction fees. These features make EOS a serious competitor of Ethereum (although EOS’s ICO actually supports Ethereum).

ælf is a decentralized self-evolving cloud computing network.To establish a Blockchain infrastructure for various commercial requirements, ælf provides a highly efficient multi-chain parallel-processing system with cross-chain communication and self-evolving governance. It brings three innovations namely scalable nodes on a cluster of computers, resource isolation for smart contracts via “one chain to one smart contract” and voting through token holders.
ELF tokens are used to pay resource fees in the system, such as the deployment of smart contracts, operating and upgrading of systems (transaction fees, cross-chain data transfer fees). It also enables the community to vote on major decisions, such as electing mining nodes, introducing new features to the system and other major decisions.
