The invention discloses a distributed network and ecological system based on an innovative reputation proof consensus protocol. The system comprises an application layer, a virtual machine, an excitation layer, a consensus layer, a network layer and a data layer, a data structure of a DAG directed acyclic graph is adopted to maintain the forward expandability of the system; a light node client ofthe smart phone is supported to resist decentralization of the system; dispersibility, and reliable security are maintained, a friendly DApp and a side chain development environment are provided to meet the requirement that some applications are stored in a large file; low transaction cost, user information protection, technical requirements on aspects of side chain and smart contract iteration, bug repair and the like are met. The method solves the difficulty in expandability and dispersity of the block chain, is a most feasible block chain ecosystem for high-frequency small and micro transactions and social applications at present, improves the reputation value through active social interaction and active use of commercial applications in the ecosystem by a user, increases the probability of being selected as a credible light node, and is convenient to popularize and use.
