Benefit allocation method, apparatus, and electronic device

Abstract

A computer-implemented method includes receiving a participation request from a participant requesting a blockchain resource; invoking a first smart contract that generates a random character sequence for the participant, the generated random character sequence satisfying a predetermined rule; publishing the random character sequence and identity information of the corresponding participant on a blockchain in a manner that identifies the correspondence; and invoking a second smart contract for allocating a benefit certificate corresponding to the blockchain resource to the participant, wherein the second smart contract is used to: obtain a target character sequence satisfying the predetermined rule that is generated later than the generation of the random character sequence and published on the blockchain; and allocate a first benefit certificate to the participant when the random character sequence matches the target character sequence; and publishing a matching result between the random character sequence and the target character sequence on the blockchain.
