Block chain-based power transaction system data security storage method and system

The invention discloses a block chain-based power transaction system data security storage method and system. The method comprises the steps of: verifying the identity of each transaction subject by using a block chain management and control platform; accessing a service interface; and verifying parameters. According to the invention, based on the identity authentication service of the block chain, unified credible management of business identities among multiple subjects such as a power transaction center, a power generation enterprise, a power selling enterprise, a power utilization enterprise and a power grid enterprise is realized. According to the method, the problem of mutual trust of identities among multiple subjects is solved, and efficient mutual trust of data of each business link of the power transaction system can be effectively realized, and therefore, the efficient sharing of data is realized through node synchronization. 本发明公开了一种基于区块链的电力交易系统数据安全存储方法及系统，其中方法包括：使用区块链管控平台验证每个交易主体的身份；访问业务接口；参数校验。本
