[0002] A domain name is a name composed of a string of names separated by dots, which is the name of a computer or a computer group on the Internet, and is used for positioning and identifying the computer during data transmission. Since IP addresses are inconvenient to remember and cannot display the name and nature of address organization, domain names are used to map domain names and IP addresses through the domain name system DNS, making it more convenient to access the Internet. As a key resource on the Internet, domain names can be obtained by purchasing the ownership of target domain names. When it is desired to sell the held domain name, either the domain name holder and the buyer negotiate privately to trade, but there is a certain risk of transaction, such as easy one-sided breach of contract after the transaction fee is received; or a centralized trading market is needed as an intermediary, but a transaction guarantee fee needs to be paid.

[0055] In order to enable those skilled in the art to better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be described clearly and completely in conjunction with the drawings in the embodiments of the present specification. Obviously, the described embodiments are only some of the embodiments of the present specification, not all the embodiments. Based on the embodiments in the present specification, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present specification.

[0056] A scheme for transferring domain name ownership based on a blockchain according to the present specification will be described in detail below through specific examples.

[0057] Key terms

[0058] Blockchain technology: It is a new distributed infrastructure and computing paradigm that uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automatic script code to program and operate data. In essence, it is a shared database, and the data or information stored therein has the characteristics of non-falsification, full traceability, transparency, collective maintenance, etc. Based on these characteristics, blockchain technology lays a solid foundation for trust, creates a reliable cooperation mechanism, and has broad application prospects. According to the access mechanism, blockchain is divided into public chain, alliance chain and private chain.

[0059] Smart contract: a program running in a blockchain system, with the characteristics of automatic execution according to the set logic and unalterable execution results. The smart contract is a collection of codes and data, and the whole transaction process is embodied by digital code, and the transaction can be automatically completed when the transaction conditions are met. The white paper of China's blockchain industry in 2018 defines the smart contract as: an event-driven, stateful, multi-party recognized, running on the blockchain and automatically processing assets according to the preset conditions.

[0060] The purpose of the present application is to realize the decentralized transaction of domain name ownership transfer and improve the credibility and security of the transaction. Domain name is a string divided by dots, used to identify and locate hosts or host groups on the Internet, corresponding to Internet protocol addresses. Domain names are arranged in a tree-like hierarchical structure from high to low, including root domain, top-level domain and secondary, tertiary domain, etc. Top-level domains are divided into two categories: general top-level domain and country and region code top-level domain according to the type of operating agency; divided into ASCII top-level domain and multi-language top-level domain according to the language type. The domain name investment and transaction field is concerned, and the market has entered the adjustment period after the market boom, especially the market situation drives the active development of domain name transaction platform, the introduction of financial tools, the diversification of transaction methods and other new methods and new models, and the development direction of domain name market is explored. But the domain name investment and transaction market is not mature, there are unlicensed top-level domains entering the market, false or exaggerated propaganda leading to price virtualization, etc. It needs to be further standardized. Usually, the transaction process of the transfer of ownership of the Internet domain name includes: valuation, price negotiation, down payment, contract signing and ownership transfer. Especially for the transfer of ownership, the domain name service provider can realize the transfer of ownership by presenting the sales contract of both parties and the identity information of the buyer. After the transfer is completed, the domain name displays the information of the buyer, and the state domain name management system can be queried.

[0061] Embodiment one

[0062] Embodiments of the present application use a smart contract to replace an offline contract and the ownership transfer transaction process to implement blockchain-based domain name ownership transfer. Since the smart contract runs in the blockchain system and has the characteristics of automatic execution according to the set logic and the execution result cannot be tampered with, its code and data collection make the entire transaction process embodied by digital code. In the case of meeting the transaction conditions, the transaction can be automatically completed without using the application architecture of the central server + software platform, so that the smart contract can realize the whole process transaction from the transfer-out application, information publishing, transfer-in application, and transfer confirmation in the domain name transfer process. Therefore, the technical idea of the embodiment scheme of the present application is to realize the on-chain transaction of domain name ownership transfer through the definition of a blockchain smart contract, that is, the blockchain serves as the guarantee for the domain name transaction, the hash lock is used as the unlocking voucher, the DNS record is used as the identifier of the domain name on-chain ownership transaction, the smart contract is used to execute the ownership transfer process, and the transaction of the domain name between users of different domain name service providers is realized. Therefore, as shown in Figure 1 the blockchain-based domain name ownership transfer method of the embodiment of the present application is shown in the schematic diagram, which includes a blockchain, a first user, a second user, a first domain name service provider, and a second domain name service provider; wherein the first user performs a domain name ownership transfer-out transaction through the first domain name service provider, and the second user performs a domain name ownership transfer-in transaction through the second domain name service provider; the method includes:
