A blockchain consensus method includes: on the basis of transaction data and a verifiable delay function, a node generating a target block, or synchronously acquiring a target block from other nodes; determining, from among multiple sub-blockchains, a target sub-blockchain based on information of a target block, and adding the target block to the target sub-blockchain; then, acquiring respective corresponding effective block sequences from the multiple sub-blockchains; performing global sorting on effective blocks on the basis of logic clocks respectively corresponding to acquired effective blocks, and acquiring a global blockchain. A global blockchain is acquired by using a means of multi-chain consensus, thereby improving the expandability and transaction throughput of a blockchain system in a large-scale open network environment. Acquiring a global blockchain by performing global sorting on effective blocks on the basis of logic clocks corresponding to the effective blocks can better improve the security of a multi-chain system.

The present invention provides a resource file processing method based on a blockchain structure. The method includes a member node in a blockchain including at least one supervision node and at least one member node constructs a resource file registration request according to a user instruction, and sends the resource file registration request to one of the at least one supervision node. According to the resource file registration request from any member node, the at least one supervision node audits and registers a resource file indicated by the resource file registration request, and transmits the registration result back to the member node initiating the resource file registration request. The at least one member node performs an operation on a real physical resource associated with the registered resource file by performing data communication with another member node.
