EtherArk (Ether Ark) has created a blockchain platform with high concurrency and suitable for general smart contract development through the CMPoS consensus mechanism. There are two decentralized systems on the chain: the decentralized autonomous community and the public welfare system on the chain. To solve credit problems through blockchain technology, blockchain technology can be used in the following aspects in public welfare undertakings: the first is to make public welfare products credible, and the second is to make relevant parties of public welfare behaviors credible , and the third is to make the entire public welfare process credible and efficient. At the same time, the high TPS and Power mechanism will also better serve third-party developers to develop on the main network, lower the threshold for blockchain development, and lay a foundation for the promotion and use of Dapp.
