FES (Financial Ecosystem Chain) is a distributed ledger digital asset solution based on Ethereum smart contracts, and the platform adopts the underlying technology of blockchain. Through the financial ecological chain (FES), the commercial blockchain has unlimited capacity, the ability to realize basic free and protect commercial secrets, and connect different businesses and scenarios through technology to achieve efficient collaboration. It is used in the financial industry, online lending, valid securities, fixed assets, digital assets, gambling, and non-performing assets. Using the FBA consensus mechanism, the Yous consensus mechanism has four key attributes at the same time: decentralized control, flexible trust, low latency, and progressive security. Compared with mainstream consensus algorithms, FBA is the result of building on the Federal Byzantine Agreement, which is the first provable security consensus mechanism. At the same time, the RAID5 algorithm mechanism is adopted in data storage, that is, when data is synchronized, in order to improve the throughput of the system, some nodes are selected for fast consensus of the RAID5 algorithm mechanism to improve the network throughput of the financial ecological chain. In this way, high throughput of data is realized under the premise of ensuring security.
