[Abstract] A new authentication system design based on Ethereum smart contract technology is proposed. The platform architecture includes a data layer, a network layer, a consensus layer, and an interface layer. The point to point (P2P) technology is used to distribute data to each node, then a distributed authentication mode can be implemented, and hacker attacks can be resisted; the elliptic curve digital signature algorithm (ECDSA) and the improved Merkel tree are applied to ensure the authenticity of the data. This design is highly scalable, high reliability and high security, and supports unified authentication on different platforms.
