Abstract

The invention discloses an information storage method and system based on a block chain, computer equipment and a storage medium. The information storage method comprises the following steps: if to-be-stored information is received, generating a public key and a private key according to a secret key generation rule, judging whether a valid identity certificate exists or not according to a certificate judgment rule, if not, sending an identity certificate acquisition request to a management server so as to acquire an effective identity certificate, associating the public key with the valid identity certificate so as to obtain associated information, sending the associated information to the management server, signing the to-be-stored information according to a signature rule and the privatekey so as to obtain to-be-stored information containing a signature value, associating the to-be-stored information with the public key and the signature value so as to obtain associated storage information, and performing distributed storage. Through the above-mentioned information storage method, the identity certificate and the to-be-stored information are stored respectively, so repeated storage of the identity certificate due to the fact that the identity certificate is added into the to-be-stored information is avoided; the storage space is saved; and the data information storage efficiency is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a block chain-based information storage method, system, computer equipment and storage medium. Background technique [0002] When storing data information based on blockchain technology, in order to control the authority and privacy protection of each node in the blockchain, a certificate system based on the PKI system (Public Key Infrastructure) can be used. In order to ensure The validity of the signature in the data information, the data information from the blockchain node needs to carry the certificate information corresponding to the node, resulting in the need for a large amount of storage space when storing the data information, and affecting the transmission efficiency of data between nodes, from Multiple copies of data information on the same node contain the same certificate information. Due to repeated storage of certificate information, storage resources ar...
