Patent attributes
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for blockchain-based reconciliation are provided. One of the methods includes: uploading, by a service-provider node, transaction information to the blockchain, wherein the transaction information comprises an identifier of a service-consumer node and information associated with a transaction fee; initializing, by the service-provider node, a settlement state of the transaction fee in a ledger of the service-provider node; obtaining, by the service-provider node, a settlement result of a transaction fee associated with the transaction information based on an identifier of the service-provider node in the settlement result, wherein the settlement result is uploaded by the service-consumer node; and updating, by the service-provider node, the settlement state in the ledger of the service-provider node based on the settlement result upon confirming the settlement result.
