Title:
METHOD AND SYSTEM FOR MANAGING AND PARSING TOP-LEVEL DOMAIN ON BASIS OF BLOCKCHAIN
Document Type and Number:
WIPO Patent Application WO/2021/237941
Kind Code:
A1
Abstract:
Provided are a method and system for managing and parsing a top-level domain on the basis of a blockchain. The method comprises: a master node receiving request information which is used for operating a top-level domain resource record and is sent by a request node, and encapsulating master node information and the request information, which has passed verification, in an advance preparation message so as to perform broadcasting; each common node verifying the received advance preparation message, and generating, after verification has been passed, a preparation message so as to perform broadcasting, wherein the preparation message comprises the request information, a request information verification identifier and current node information; and each node verifying the received preparation message, and if the number of sending nodes for the preparation information which has passed verification reaches a consensus threshold, adding an operation result, which corresponds to the request information in the preparation message, to a new block within a local blockchain. By means of the method, the security of operating a top-level domain resource record stored in a block can be ensured, top-level domain hijacking attacks are avoided, and consistency in operation, processing and storage of the top-level domain resource record by multiple nodes is realized.
