Embodiment Construction

[0048] Embodiments of this specification will be described below with reference to the accompanying drawings.

[0049]figure 1 A schematic diagram showing a system for domain name configuration according to an embodiment of the present specification. Such as figure 1 As shown in , the system includes a domain name issuing platform 11, and the domain name issuing platform 11 makes domain names owned by issuing domain names to multiple blockchain platforms. The multiple blockchain platforms include a blockchain platform 12. In order to own a blockchain domain name, the blockchain platform 12 needs to apply to the domain name distribution platform 11, for example, to apply for the domain name "chain1". After the domain name issuance platform 11 determines that the domain name "chain1" does not have the same name as an existing blockchain domain name, it generates a private key and a public key corresponding to "chain1", and then generates a domain name certificate including the...

Abstract

The embodiment of this specification provides a method and device for updating the domain name configuration of the blockchain, the method is executed by the domain name owner device, the domain name owner has the private key corresponding to the first domain name, and the first domain name The configuration is currently determined based on the first domain name configuration package, which includes the first domain name, the verification root of the first blockchain, and the first version number. The method includes: generating a second domain name configuration package, the The second domain name configuration package includes the first domain name, the verification root of the second block chain, and a second version number, and the second version number is a version number different from the first version number; using the Digitally signing the second domain name configuration package with the private key; publishing the second domain name configuration package and its digital signature.

Description

technical field [0001] The embodiment of this specification relates to the field of blockchain technology, and more specifically, to a method and device for updating the domain name configuration of the blockchain. Background technique [0002] Blockchain technology, also known as published ledger technology, is a decentralized published database technology, which is characterized by decentralization, openness, transparency, non-tamperability, and trustworthiness. Every piece of data in the blockchain will be broadcast to the blockchain nodes of the entire network, and each full node has a full amount of consistent data. With the popularity of blockchain technology, many different types of chains have emerged, which are applied in fields such as finance, health care, supply chain, asset management and traceability. However, most on-chain applications (cryptocurrency or smart contracts) cannot cross the boundaries of the current chain, and cannot cooperate with other chains ...
