Ethereum Name Service (ENS) offers a distributed, open, and scalable naming system on the Ethereum blockchain, translating machine-readable blockchain addresses into human-readable names, thereby simplifying user interactions with smart contracts. ENS functions similarly to Domain Name Service (DNS) but replaces blockchain addresses with readable names instead of IP addresses. Chainlink is leveraging ENS to make its Data Feeds more accessible by providing recognizable Chainlink Price Feed addresses, such as `eth-usd.data.eth`, instead of long, complex contract addresses. This integration enhances the discoverability and accessibility of Chainlink’s oracle networks on the Ethereum blockchain. In JavaScript environments, using ENS for domain resolution is straightforward and supported by libraries like web3.js. The process involves creating node hashes using a recursive algorithm, with emphasis on name normalization according to UTS46 standards. For on-chain resolution, Solidity contracts can implement interfaces to convert node hashes to addresses, ensuring correct blockchain interactions. Chainlink’s adoption of ENS underscores its commitment to simplifying blockchain address usage and ensuring accurate interactions.
