IOSG: An article to understand the Ethereum ENS world built by 360,000 ETH and 520,000 domain names

ENS architecture

Data Sources:https://docs.ens.domains/

• It mainly includes two components: registry and resolver. The ENS registry is a smart contract that maintains a list of all domain names and subdomain names, and stores three key information about each domain name: the owner of the domain name (owner); the resolver of the domain name; all records under the domain name The cache lifetime (cache). The ENS registry is very simple, and its job is to map a domain name to the resolver responsible for resolving this domain name. Resolvers are responsible for converting domain names into addresses.

Data Sources:

subdomain

At the same time, users can also create subordinate subdomains based on the parent domain name of ENS. For example, IOSG wants to configure a subdomain name for each employee under iosg.eth, which is very simple in ENS. If you already have a .eth domain, you can create some new subdomains by clicking the Subdomains button on the ENS Manager. Once the subdomain is created, the details of the subsequent settings are very similar to the parent domain name, and the owner of the subdomain can control the subdomain and set records. This means that subdomains like steven.iosg.eth can also resolve to a wallet address.

As the most mainstream centralized domain name naming system on Ethereum, ENS has gradually become a common tool for both developers and end users. According to data from Dune Analytics, the total number of domain names created on ENS is 524,335, including 104,043 .eth domain names and 95,017 subdomain names. The number of registered participants is 56,791.

It is worth noting that whether ENS needs to be decentralized has been widely debated. It needs to be clear that the core motivation for the transformation of a project or application from centralization to decentralization is to reduce the possibility of malicious attacks and manipulation of the entire system through node distribution. Thereby avoiding the problems of legal compliance risks and centralized control. For example, uniswap abandoned the centralized market maker by introducing AMM, allowing smart contracts to complete order matching, and minimized the risk of centralization doing evil. But at the same time sacrifices were made. High gas fee and high slippage are the sequelae of this trade-off. Based on this logic, first of all, there is no legal risk in the centralized mechanism of ENS. Centralized management is only ENS enquiry, which is the address of the resolver obtained when a user indexes a domain name. This is independent of the parser itself. So even if ENS Inquiry is controlled, the final machine identifier cannot be resolved.
