Top-level domain name management and analysis method and system based on block chain

The embodiment of the invention provides a top-level domain name management and analysis method and system based on a block chain. The method comprises the steps that a main node receives request information, transmitted by a request node, for top-level domain name resource recording operation, and packages the information of the main node and the request information passing the verification intoa pre-preparation message for broadcasting; each common node verifies the received pre-preparation message and generates a preparation message for broadcasting after passing the verification, and thepreparation message comprises request information, a request information verification identifier and current node information; and each node verifies the received preparation message, and if the number of the preparation message sending nodes passing the verification reaches a consensus threshold, an operation result corresponding to the request information in the preparation message is added to anew block in the local blo
