ENS (ETH Name Service) Is a service that associates a wallet address with a specific name, like DNS in Web3.0. You can type ENS in MetaMask and convert it to an address, or you can display the ESN name in Etherscan. Anyone can get it at a low price (three characters or less are expensive).

Since ENS uses the NFT mechanism (a unique address is linked with the ERC-721 token), it can be bought and sold on OpenSea. Budweiser gets an ENS called "beer.eth" after Visa bought a Cryptopunks NFT last year. As with trademarks, the number of people who are subject to speculation and acquire ENS that can be resold at a high price has increased dramatically.

今話題なのは、Amazon.eth に100万ドルの bid が入ったこと。誰がbidしたかはともかく、これがまあweb3.0らしいニュースって事ですかね。
