Random source generation method, electronic equipment, system and medium

The invention provides a random source generation method, electronic equipment, a system and a medium. The method comprises the following steps: acquiring a plurality of verifiers; based on a verifiable random function algorithm, selecting from the plurality of verifiers to obtain a threshold group with at least one group member; when a target hash value sent by the group member in a transaction form is received, recording the target hash value to a node of a block chain; when character strings sent by the group members in a transaction form are received, verifying the validity of each character string based on the target hash value, and determining the valid character strings as target character strings; calculating a first number of the target character strings and a second number of thetarget hash values; and when the first number and the second number meet a configuration condition, generating a random source according to the target character string. According to the method, the random source which is ran
