.eth refers to a domain name system specifically for the Ethereum blockchain. It allows users to replace long and complex wallet addresses with a simpler, human-readable format. For example, instead of using a string of letters and numbers, a user can send cryptocurrency to an address like yourname.eth.This system is part of the Ethereum Name Service (ENS), which works similarly to traditional domain name systems but is decentralized. ENS enables users to create unique identifiers that can represent Ethereum addresses, smart contracts, or other resources.These domains can be bought, sold, or transferred on the Ethereum network. Once you own a .eth domain, you have control over its management and can link it to various digital assets, making transactions and online interactions easier.By using .eth domains, users enhance usability and accessibility, helping to bridge the gap between blockchain technology and everyday users.
