IDENTITY AUTHENTICATION METHOD BASED ON ALLIANCE CHAIN, AND TERMINAL DEVICE

摘要

The present application is applicable to the technical field of blockchains. Provided are an identity authentication method based on an alliance chain, and a terminal device. The method comprises: submitting identity identification data and an addition request of a first blockchain node to a genesis block in an alliance chain; if authentication passing information returned by the genesis block is received, monitoring whether a communication request of a second blockchain node is received; if the communication request of the second blockchain node is received, acquiring identity identification data of the second blockchain node from the communication request, and carrying out identity authentication on the second blockchain node according to the identity identification data of the second blockchain node; and if the identity authentication carried out on the second blockchain node is passed, returning data corresponding to the communication request to the second blockchain node. By means of the method, the reliability of the identity authentication method based on an alliance chain is effectively improved.
