ENS - Ethereum Name Service

What is ENS?

The Ethereum Name Service (ENS) is a distributed, open, and extensible naming system built on the Ethereum blockchain. ENS's primary function is to map human-readable names like 'alice.eth' to machine-readable identifiers, including Ethereum addresses, other cryptocurrency addresses, content hashes, and metadata.

Key Features of ENS

• Decentralized Naming: ENS operates on a decentralized system, similar to DNS, allowing users to have human-readable names associated with their Ethereum addresses.

• Hierarchical Structure: ENS uses a hierarchical structure of dot-separated domains, granting full control to domain owners and supporting subdomains.

How ENS Works

ENS allows users to register and configure domains, similar to traditional domain name systems. Owners of top-level domains, such as '.eth' and '.test', have control over their subdomains, enabling easy customization.

Benefits of ENS

• Human-Readable Addresses: ENS makes it possible to use human-readable names in place of complex Ethereum addresses.

• Reverse Resolution: ENS supports 'reverse resolution', associating metadata with Ethereum addresses.
