In this embodiment of the present application, different areas may be respectively deployed with respective domain name blockchain networks. For each region, an organization participating in DNS service in the region may jointly construct a domain name block chain network, where a domain name block chain in the domain name block chain network is used to record domain name registration information of the region, that is, is used to record an association relationship between a domain name and an IP address in the region; further, owner account information of the domain name in the area may be recorded. If any domain name exists in the domain name block chain of any region, the computer corresponding to the domain name is located in the region. 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.

The target domain name may refer to a domain name to be analyzed by a user node (i.e., a client), the first domain name blockchain network may refer to a domain name blockchain network associated with the same area as the user node, and the first domain name blockchain networks of different user nodes may be different. That is, for each region, the domain name blockchain network of the region may be used as the first domain name blockchain network of the user node in the region. The first domain name blockchain node may further be deployed with a certificate (CA certificate) that the organization node may have a Certificate Authority (CA), and the first domain name blockchain node may endorse its own node data using the CA certificate.

The second domain name blockchain network may refer to a domain name blockchain network associated with the same region as the target domain name. The user node may create a blockchain account, resulting in 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 first domain name 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 block chain data, and the lightweight node may record only a block header but not a block. In addition, the user node may not belong to each domain name blockchain network, e.g., the user node may create blockchain accounts by running a blockchain wallet.

The domain name block chain network can also be deployed with a basic level and at least one other level, wherein the domain name block chain of the basic level stores the association relationship between the domain name and the domain name block chain, and the domain block chain of the other level stores the association relationship between the domain name and the next level of the domain block chain.

Fig. 2b is a schematic diagram of an architecture between regional block chains at different levels according to an embodiment of the present disclosure. Referring to fig. 2b, taking as an example that other hierarchies may include a root hierarchy and a parent hierarchy, a next level of the root hierarchy may be a parent hierarchy and a next level of the parent hierarchy may be a base hierarchy. Specifically, the root level block chain stores an association relationship between the domain name and the parent level block chain, and the parent level block chain stores an association relationship between the domain name and the base level block chain. It should be noted that, in the embodiment of the present application, the number of the regional block chains in each level except for the root-level regional block chain is not specifically limited, for example, a country may have one parent-level regional block chain, and N parent-level regional block chains may be used in total; a city may have a base level regional blockchain, and a country may have M base level regional blockchains.

Referring to fig. 2b, taking as an example that other hierarchies may include a root hierarchy and a parent hierarchy, when a first domain name block chain node (i.e., a first domain name block chain network) fails to resolve a target domain name according to first domain name registration information, the first domain name block chain node may send the target domain name to a root level regional block chain node through a cross-chain technique, determine, by the root level regional block chain node (i.e., a root level regional block chain network), parent level regional block chain network information associated with the target domain name, and acquire parent level regional block chain network information fed back by the root level regional block chain node; the first domain name block chain link point can also send a target domain name to the parent-level region block chain link point according to the network information of the parent-level region block chain through a chain crossing technology, the parent-level region block chain link point determines the basic-level region block chain information associated with the target domain name, and the basic-level region block chain network information fed back by the parent-level region block chain link point is acquired; the first domain name block chain node also can send a target domain name to the base level region block chain node according to the base level region block chain network information through a chain crossing technology, and the base level region block chain node determines second domain name block chain network information associated with the target domain name. And the first domain name block chain node can also acquire a second resolution result from the second domain name block chain network according to the second domain name block chain network information, and return the second domain name resolution result to the user, so that the user accesses the computer associated with the target domain name.

The cross-chain checking auxiliary information can be determined according to the type of the second domain name block chain network. Specifically, under the condition that the second domain name block chain network adopts a BFT common identification mechanism, the cross-chain check auxiliary information can be used for verifying whether a second analysis result fed back by more than 2/3 of total identification nodes is the same; under the condition that the second domain name block chain network adopts a CFT consensus mechanism, the cross-chain checking auxiliary information can be used for verifying whether at least one consensus node feeds back a second resolution result or not; in a case that the second domain name block chain network is a federation chain based on an MSP (member Service Provider) system, the cross-chain verification auxiliary information may be used to verify whether a node certificate of the second domain name block chain node is valid and whether signature data of the second resolution result by the second domain name block chain node is valid.

Specifically, in the process of cross-chain processing, the second domain name block chain node in the second domain name block chain network further determines cross-chain checking auxiliary information, and may send the second resolution result and the cross-chain checking auxiliary information to the first domain name block chain node, so that the first domain name block chain node checks the cross-chain checking auxiliary information.

The first domain name block chain node can perform verification by itself, and the relay node independent of the first domain name block chain network and the second domain name block chain network can perform verification. The reliability of domain name resolution can be further improved by introducing check on the cross-chain query result.

In an optional implementation manner, feeding back the second resolution result to the initiator of the domain name resolution transaction request includes: signing the second analysis result to obtain signature data; and returning the second analysis result, the signature data and the block chain link point certificate to an initiator of the domain name analysis transaction request, and verifying the second analysis result by the initiator according to the signature data and the block chain link point certificate and using the second analysis result according to a verification result.

The initiator can adopt the account public key of the first domain name block chain node to verify the signature data, and can also adopt a CA root certificate preset by the initiator to verify the validity of the CA certificate of the first domain name block chain node, and under the condition that both the signature verification result of the signature data and the validity of the CA certificate pass, the initiator can trust and use the second analysis result; and under the condition that the signature verification result of the signature data and/or the validity check of the CA certificate do not pass, the initiator can reinitiate the resolution transaction request for the target domain name to other first domain name block chain nodes. The accuracy of the second analysis result can be further improved through the verification of the validity of the signature and the CA certificate.

According to the technical scheme provided by the embodiment of the application, the cross-link check is introduced in the cross-link interaction process of the first domain name block chain link and the second domain name block chain link, and the check of the user node on the data sent by the first domain name block chain link can be introduced, so that the reliability of the second resolution result can be further improved.

For each region, an organization participating in DNS service in the region may jointly construct a domain name block chain network, where a domain name block chain in the domain name block chain network is used to record domain name registration information of the region, that is, is used to record an association relationship between a domain name and an IP address in the region; also, the owner account information of the domain name in the area may be recorded. If any domain name exists in the domain name block chain of any region, the computer corresponding to the domain name is positioned in the region. The target domain name may refer to a domain name to be resolved by a user node (i.e., a client), the first domain name blockchain network may refer to a domain name blockchain network associated with the same domain as the user node, and the first domain name blockchain networks of different user nodes may be different.

The second domain name blockchain network may refer to a domain name blockchain network associated with the same region as the target domain name. The user node may create a blockchain account, resulting in a blockchain address, a blockchain public key, and a blockchain private key.

Specifically, when the user node needs to access a certain domain name, the domain name may be used as a target domain name, a domain name resolution transaction request including the target domain name is generated, and the domain name resolution transaction request is sent to the first domain name block link point. The first domain name block chain link point responds to the domain name resolution transaction request and calls a domain name processing contract (namely a domain name processing intelligent contract) to resolve the target domain name; obtaining a first analysis result under the condition of successful analysis; under the condition that the resolution fails, the first domain name block chain link point can also determine a second domain name block chain network associated with the target domain name, and forward a domain name resolution transaction request to the second domain name block chain network (i.e., a second domain name block chain node), so as to instruct the second domain name block chain node to perform resolution on the target domain name according to second domain name registration information in the second domain name block chain to obtain a second resolution result. The domain name resolution service is provided through the domain name block chain network, so that the problems of centralized downtime, cheating or unreasonable cost and the like can be avoided; in addition, by respectively deploying respective domain name block chain networks for different areas, compared with the situation that the same domain name block chain network is reused in different areas, the domain name block chain network system can play a role in data fragmentation, and reduces the storage and calculation resource consumption of a single domain name block chain, so that the transaction request processing efficiency in the domain name block chain network is improved, namely the domain name resolution efficiency is improved.

Fig. 6 is a schematic flowchart of another domain name resolution method based on a blockchain according to an embodiment of the present disclosure. The present embodiment is an alternative proposed on the basis of the above-described embodiments. Referring to fig. 6, the domain name resolution method based on the block chain provided in this embodiment includes:

s610, determining a target domain name to be analyzed.

S620, sending a domain name resolution transaction request including the target domain name to the first domain name blockchain network.

Wherein the domain name resolution transaction request is used to instruct the first domain name blockchain network to perform the following: determining a second domain name block chain network associated with the target domain name under the condition that the target domain name is failed to be analyzed according to first domain name registration information in a first domain name block chain; and forwarding the domain name resolution transaction request to the second domain name block chain network, wherein the domain name resolution transaction request is used for indicating that a target domain name to be resolved is determined according to a second resolution result obtained by resolving the target domain name according to second domain name registration information in the second domain name block chain.

The first domain name block chain node can sign the second analysis result to obtain signature data; and returning the second analysis result, the signature data and the CA certificate of the first domain name block chain node to the user node. Correspondingly, the user node can adopt the account public key of the first domain name block chain node to check the signature data, can also adopt a preset CA root certificate to check the validity of the CA certificate of the first domain name block chain node, and can trust and use the second analysis result under the condition that both the signature check result of the signature data and the validity check of the CA certificate pass. In addition, after the user node trusts the second resolution result, if the second resolution result is the target ID address associated with the target domain name, the user node may also write the mapping relationship between the target domain name and the target IP address into the cache of the initiator. It should be noted that, in the process of sending other data to the user node by the first domain name block node, the signature data and the CA certificate of the first domain name block chain node may also be sent for the user node to check, so as to improve the reliability of the sent data. For example, when the target domain name is successfully resolved according to the first domain name registration information, the first domain name blockchain node sends the first resolution result to the user node, and may also send signature data and a blockchain node certificate together.

In an optional implementation manner, before sending the domain name resolution transaction request including the target domain name to the first domain name blockchain network, the method further includes: determining whether a target IP address associated with the target domain name exists in a cache of a local node; and generating the domain name resolution transaction request under the condition that the target IP address does not exist in the cache.
