    [0029] [0029] FIG. 3 is a schematic diagram of a domain name registration process for a top-level domain according to an embodiment of the present application;

    [0034] [0034] In the present application, a blockchain or blockchain data is accounting information generated based on transaction information when a transaction occurs in the blockchain network. Specifically, a plurality of transactions constitute a block data, and a plurality of block data constitute a blockchain with a timestamp. The blockchain network includes nodes that establish a point-to-point network connection with one another. Each of the nodes is configured with a corresponding consensus mechanism, for example, a smart contract, and has a sufficient operating capability to perform transaction verification and accounting processes. The node further has a standardized interface specification, so as to access more nodes or other types of blockchain networks through the interface specification. A public chain is a point-to-point network structure constituted by a plurality of nodes in the blockchain network, where each of IS the nodes has a distributed storage function and a transaction and accounting function. The nodes on the public chain provide a uniform interface specification to the outside.
    [0035] [0035] A possible system architecture to which an embodiment of the present application is applicable is described first with reference to FIG. 1 bellow.
    [0036] [0036] For example, FIG. 1 is a schematic structural diagram of a blockchain-based decentralized domain name registration system according to an embodiment of the present application. The system may include a public chain constituted by a plurality of = nodes and a subchain constituted by some of the nodes in the public chain. Obviously, N in this embodiment, a node in the public chain may also serve as a subchain node. 2 Because the subchain is constituted by some of the nodes in the public chain, a node in N 25 the subchain is also a node in the public chain. In other words, the nodes constituting a the subchain have the same smart contract and function as the nodes of the public = chain. S [0037] In actual application, the public chain may provide basic blockchain services, for example, transactions, verification, and storage, in the network. The public chain itself may not have a specific function corresponding to any field, but acts as a bridge to 9
    [0038] [0038] In the technical solutions provided in the present application, a root domain smart contract is configured in each node in the public chain. The smart contract is a consensus mechanism program agreed based on a blockchain transaction. Transaction operations of various functions can be implemented through using the smart contract. In this embodiment of the present application, a domain name registration service may be completed by a node through executing the root domain smart contract.
    [0039] [0039] The node in the subchain may be configured to: generate a sub domain smart contract through executing the root domain smart contract, and obtain ownership of the sub domain smart contract through contention. After a subchain node obtains ownership of a sub domain smart contract, the subchain node may act as an owner of the sub domain smart contract. In other words, the sub domain smart contract is IS configured in the subchain node.
    [0040] [0040] Because the node in the subchain has the same smart contract as the node in the public chain, the node in the subchain can directly execute the root domain smart contract to generate a sub domain smart contract. The sub domain smart contract includes a top-level domain smart contract, an application domain smart contract, and — blockchain name system (Blockchain Name System, BNS) data.
    [0041] [0041] In the blockchain name system, a domain name may be classified into a root = domain, a top-level domain, and an application domain. Further, the application domain N may be classified into a second-level domain, a third-level domain, a fourth-level 2 domain, and the like. A complete domain name is constituted by two or more parts, and N 25 — the parts are separated by periods ".", where the last "." is referred to as a root domain. a A part on the right of the first "." from the last "." is referred to as a top-level domain = (Top-Level Domain, TLD), or referred to as a first-level domain, including a valid N character string and a domain suffix. A character string part from the left of the top-level - domain to a next "." is referred to as a second-level domain (Second-Level Domain, SLD). Apart on the left of the second-level domain is referred to as a third-level domain, 10
    [0042] [0042] In this embodiment of the present application, different smart contracts are provided for different levels of domains. A root domain may correspond to a root domain smart contract, wherein the root domain smart contract may be configured to manage and maintain a top-level domain, and generate a top-level domain smart contract. The top-level domain may correspond to the top-level domain smart contract, wherein the top-level domain smart contract may be configured to manage and maintain an application domain (for example, manage a second-level domain), and generate an application domain smart contract. The application domain may correspond to the — application domain smart contract, wherein the application domain smart contract may be configured to manage and maintain BNS data. The BNS data may include information on a third-level domain, information on a fourth-level domain, and the like.
    [0043] [0043] Further the node in the subchain specifically may be configured to: generate the top-level domain smart contract through executing the root domain smart contract. IS [0044] Alternatively, the node in the subchain specifically may be further configured to: generate the application domain smart contract through executing the top-level domain smart contract.
    [0045] [0045] Domain name registration is described in detail below based on the system architecture shown in FIG. 1 and the content described above.
    [0046] [0046] For example, FIG. 2 is a schematic flowchart of domain name registration by a domain name registration system according to an embodiment of the present — application.
    [0048] [0048] Correspondingly, the target node may be configured to: decide whether to 11
    [0049] [0049] Further after the smart contract corresponding to the to-be-registered domain name is generated by the target node, the node in the subchain still may obtain ownership of the smart contract corresponding to the to-be-registered domain name through contention. In addition, the target node may further newly add a record, which points to the smart contract corresponding to the to-be-registered domain name, of the —to-be-registered domain name to the target domain smart contract, so that domain name registration is completed.
    [0050] [0050] It can be learned from the foregoing technical solutions that the present application provides a blockchain-based decentralized domain name registration system, including a public chain constituted by a plurality of nodes and a subchain IS constituted by some of the nodes in the public chain. A root domain smart contract is configured in each node in the public chain. The node in the subchain is configured to: generate a sub domain smart contract through executing the root domain smart contract, and obtain ownership of the sub domain smart contract through contention; obtain a to-be-registered domain name, determine a target domain smart contract for managing — the to-be-registered domain name, and determine a target node having ownership of the target domain smart contract in the subchain; and send a domain name registration = reguest to the target node, so that the target node decides whether to accept the N domain name registration reguest, and generates a smart contract corresponding to the 2 to-be-registered domain name if the domain name registration reguest is accepted. In N 25 — the present application, a DNS system is deployed in a blockchain network in a form of a a subchain, to implement a complete decentralized deployment. Compared with a prior = DNS system, in the domain name registration system provided in the present S application, domain name registration is free of being controlled by ICANN, which avoids a risk of being restricted and shielded by ICANN during domain name registration in a DNS system, thereby improving cyber security of parties participating in 12
    [0051] [0051] It can be learned from the content shown in FIG. 2 that a transaction reguest received by the node (the node 1) in the subchain comes from a node 0. The node O may be an initiator node for a current domain name registration transaction, or may be a neighboring node of the node (the node 1) in the subchain. In other words, the node (for example, the node 1 shown in FIG. 2) in the subchain may be further configured to: obtain the to-be-registered domain name sent by the initiator node or the neighboring node corresponding to the node in the subchain.
    [0052] [0052] A form of a transaction between an initiator node and the node in the subchain —may vary with different actual application environments. The node in the subchain may obtain a to-be-registered domain name sent by an initiator node by the following two cases.
    [0053] [0053] In one case, if an initiator node can perform a transaction or exchange information directly with the node in the subchain, the initiator node can send a IS to-be-registered domain name directly to the node in the subchain. Such a manner is most suitable for a transaction when an initiator node and the node in the subchain are in a same blockchain network. In other words, the initiator node is also a node in the domain name registration system.
    [0054] [0054] In the other case, if an initiator node cannot perform a transaction or exchange information directly with the node in the subchain, the initiator node may broadcast a to-be-registered domain name. Specifically, the to-be-registered domain name may be = first broadcast to a neighboring node, and the neighboring node then determines, based N on its function, whether to accept or further broadcast the to-be-registered domain 2 name, until the to-be-registered domain name is received by the node in the subchain. N 25 [0055] Correspondingly, the node in the subchain may receive a to-be-registered a domain name sent by a neighboring node of the node in the subchain by the following = case: An initiator node for transaction does not know location information of a core node, N and sends a to-be-registered domain name over the blockchain through broadcast, so - that the core node may receive the to-be-registered domain name through its neighboring node as the information is spread. 13
    [0056] [0056] It should be noted that, the foregoing two cases are only examples for description. In another possible example, if an initiator node is a neighboring node of the node in the subchain, a to-be-registered domain name sent by the initiator node may be regarded as being received directly by the node in the subchain.
    [0057] [0057] Considering that the to-be-registered domain name in the present application may be different levels of domains, correspondingly, the target domain smart contract that can manage the to-be-registered domain name may vary. Domain name registration processes for different levels of to-be-registered domain names are described in detail below through examples.
    [0058] [0058] Example 1:
    [0059] [0059] FIG. 3 is a schematic diagram of a domain name registration process for a top-level domain according to an embodiment of the present application. The node (for example, a node 1 shown in FIG. 3) in the subchain may be further configured to: obtain the to-be-registered domain name, and determine the target domain smart contract for IS managing the to-be-registered top-level domain as the root domain smart contract if the to-be-registered domain name is a to-be-registered top-level domain; and decide whether to accept the registration reguest for the to-be-registered top-level domain, and generate the top-level domain smart contract corresponding to the to-be-registered top-level domain based on the root domain smart contract if the registration reguest for — the to-be-registered top-level domain is accepted.
    [0060] [0060] According to a management relationship between a domain smart contract and = a domain name, if the to-be-registered domain name is a to-be-registered top-level N domain, obviously, the target domain smart contract for managing the to-be-registered > top-level domain is the root domain smart contract. Since in the domain name N 25 registration system provided in the embodiments of the present application, the root a domain smart contract is configured in each of the nodes in the public chain, and the = nodes in the subchain are constituted by some of the nodes in the public chain, that is to N say, the root domain smart contract is also configured in each of the nodes in the - subchain, the target node to be determined by the node in the subchain is actually the node in the subchain itself, and accordingly the node in the subchain may decide 14
    [0061] [0061] Example 2:
    [0062] [0062] FIG. 4 is a schematic diagram of a domain name registration process for a second-level domain according to an embodiment of the present application. The node 3 (for example, a node 1 shown in FIG. 4) in the subchain may be further configured to: obtain the to-be-registered domain name, and determine the target domain smart contract for managing the to-be-registered second-level domain as the top-level domain smart contract if the to-be-registered domain name is a to-be-registered second-level domain, and determine the target node (for example, a node 2 shown in FIG. 4) having ownership of the top-level domain smart contract in the subchain; and send the domain name registration reguest to the target node. The domain name registration reguest may include the to-be-registered second-level domain.
    [0063] [0063] Correspondingly, the target node may be further configured to: generate the application domain smart contract corresponding to the to-be-registered second-level IS domain based on the top-level domain smart contract if accepting the domain name registration reguest.
    [0064] [0064] Example 3:
    [0065] [0065] FIG. 5 is a schematic diagram of a domain name registration process for a third-level domain according to an embodiment of the present application. The node (for 20 example, a node 1 shown in FIG. 5) in the subchain may be further configured to: obtain the to-be-registered domain name, and if the to-be-registered domain name is a = to-be-registered third-level domain, determine the target domain smart contract for N managing the to-be-registered third-level domain as the application domain smart > contract, and determine the target node (for example, anode 2 shown in FIG. 5) having N 25 ownership of the application domain smart contract in the subchain; and send the a domain name registration reguest to the target node. The domain name registration = reguest may include the to-be-registered third-level domain. S [0066] Correspondingly, the target node may be further configured to: generate BNS data corresponding to the to-be-registered third-level domain based on the application 30 domain smart contract if accepting the domain name registration request.
    [0067] [0067] It should be noted that, if the to-be-registered domain name is a fourth-level or higher-level domain, domain name registration may be implemented also through using the method shown in FIG. 5. Description of details is omitted herein.
    [0068] [0068] Based on a same invention concept, an embodiment of the present application further provides a blockchain-based decentralized domain name registration method. FIG. 6 is a schematic flowchart of a blockchain-based decentralized domain name registration method according to an embodiment of the present application. The method may be applied to the decentralized domain name registration system described above, and the system may include a public chain constituted by a plurality of nodes and a —subchain constituted by some of the nodes in the public chain. The node in the public chain is configured with a root domain smart contract. The node in the subchain is configured to: generate a sub domain smart contract through executing the root domain smart contract, and obtain ownership of the sub domain smart contract through contention. The method may specifically include the following steps:
