Embodiments disclosed herein provide a method and system for management and resolution of a blockchain-based top-level domain. The method comprises: a master node receiving request information for operations on top-level domain resource record from a requesting node, and encapsulating master node information and authenticated request information into a pre-preparation message; each normal node verifying the pre-preparation message, and after successful verification, generating a preparation message comprising request information, a request information verification identifier, and current node information; each node verifying the preparation message, when the number of authenticated preparation message sending nodes reaches a consensus threshold, adding an operation result corresponding to the request information to a new block in a local blockchain. The method ensures security of operations on top-level domain resource record stored in the block, resists top-level domain hijacking attacks, and provides consistent processing and storing of operations on top-level domain resource record by multiple nodes.
