Fig. 1 is a schematic flowchart of a domain name processing method based on a block chain according to an embodiment of the present application. The embodiment of the application can be applied to the conditions of registration, transaction or analysis and the like of the domain name. The domain name processing method based on the blockchain disclosed in this embodiment may be executed by an electronic device, and specifically may be executed by a domain name processing apparatus based on the blockchain, which is configured in a blockchain node, and the apparatus may be implemented by software and/or hardware and is configured in the electronic device. Referring to fig. 1, the domain name processing method based on the block chain provided in this embodiment includes:

In this embodiment of the present application, each of the organization nodes participating in DNS processing may jointly establish a block chain network, each organization node may have a certificate (CA certificate) issued by a Certificate Authority (CA), and the organization node may endorse its own node data using the CA certificate. Domain name processing contracts (namely domain name processing intelligent contracts) can be deployed in the block chain nodes of the block chain network, and the domain name processing contracts are used for providing block chain services such as domain name registration, domain name transaction, domain name resolution and the like according to domain name data in the block chains. The domain name information to be processed can be domain name information to be registered, domain name information to be traded, domain name information to be analyzed and the like. The embodiment of the present application does not specifically limit the type, the consensus mechanism, and the like of the block chain network, and for example, the block chain network may be a coalition chain network adopting a byzantine consensus mechanism.

Wherein, a user node (i.e. a client) can create a blockchain account, and obtain a blockchain address, a blockchain public key and a blockchain private key. It should be noted that, in the embodiment of the present application, a user node may belong to a block chain network, for example, the user node may be a lightweight node or a full-scale node, the full-scale node may record full-scale block chain data or may be configured with a domain name processing contract, and the lightweight node may record only a block header without recording a block and without configuring a domain name processing contract. In addition, the user node may not belong to the blockchain network, e.g., the user node may create a blockchain account by running a blockchain wallet.

In the case that the user node does not belong to the blockchain network, the user node may be configured with an IP address of at least one blockchain node and a CA root certificate of an organization to which the blockchain node belongs in advance. The user node may connect the blockchain network according to the IP address of at least one blockchain node, send a transaction request to the blockchain network, and may also verify the validity of the CA certificate of the organization node according to the CA root certificate.

For domain name processing transaction requests requiring consensus, such as domain name registration, domain name transaction, etc., the selected blockchain node can also synchronize the domain name processing transaction request and the execution result to other blockchain nodes in the blockchain network, and the execution result is confirmed by the other blockchain nodes based on the consensus mechanism. Still taking the consensus mechanism as a byzantine consensus mechanism as an example, the execution result is confirmed in the case that there are 2/3 total recognition nodes in the blockchain network recognizing the execution result. It should be noted that, in the case that the user node is a full-scale node, the user node itself has a block chain and a domain name processing contract, and the user node itself may execute the domain name processing transaction request, which is not described in detail. The block chain services such as domain name registration, domain name transaction, domain name resolution and the like are provided through a domain name processing contract in the block chain network, a centralized DNS system is not required, a third-party intermediary is not required to be relied on for second-hand domain name transaction, the processing efficiency and stability of domain name registration, transaction, resolution and the like can be improved, and the domain name processing cost of a user is reduced.
