Abstract
Implementations of the present specification provide methods, apparatuses, and electronic devices for resource allocation based on blockchain. The blockchain stores a mapping relationship between a digital digest of an invoice and a resource allocation state corresponding to the invoice. The method includes: receiving a target transaction submitted by a client to participate in resource allocation based on a target invoice; in response to the target transaction, calculating a digital digest of the target invoice, and querying a resource allocation state stored in the blockchain and corresponding to the digital digest; and if the detected resource allocation state is an unallocated state, invoking resource allocation logic declared in a smart contract published in the blockchain, to allocate resources to the client from a predetermined resource pool based on a predetermined allocation rule, and returning a resource allocation result to the client.
