Web3 domains are based on blockchain tech­nol­o­gy and allow for de­cen­tral­ized ad­min­is­tra­tion. They’re saved as NFTs in blockchains like Ethereum, making them cen­sor­ship-resistant and fully owned by the user. They link cryp­tocur­ren­cy wallets, de­cen­tral­ized websites and other Web3 ap­pli­ca­tions, which makes them a central part of the new, user-centered internet.

What is a Web3 domain name?

Web3 domains are unique digital iden­ti­ties that are stored on a blockchain and reg­is­tered and run as a non-fungible token (NFT). They are in­te­grat­ed as smart contracts in blockchains like Ethereum, Polygon and Solana and enable de­cen­tral­ized, un­change­able and secure name al­lo­ca­tion. They serve as addresses that can be read by humans, for example for cryp­tocur­ren­cy wallets or de­cen­tral­ized ap­pli­ca­tions (also known as DApps).

Because they are stored on a blockchain, Web3 domains are forgery-proof and enable direct in­ter­ac­tion with Web3 protocols without central control instances. They’re im­ple­ment­ed in the form of NFT standards like ERC-721 and ERC-1155, which ensures their in­ter­op­er­abil­i­ty with other blockchain ap­pli­ca­tions. The domains are a central part of the in­fra­struc­ture of the de­cen­tral­ized internet and offer a permanent digital identity that works in­de­pen­dent­ly of cen­tral­ized providers.

De­f­i­n­i­tion

Web3 refers to the next level of de­vel­op­ment of the internet, which is based on de­cen­tral­iza­tion, blockchain tech­nol­o­gy and user-con­trolled iden­ti­ties. Unlike tra­di­tion­al Web2, which is dominated by cen­tral­ized platforms and in­ter­me­di­aries, Web3 enables direct, secure and trans­par­ent in­ter­ac­tions between users. That creates an internet-based ecosystem in which property, data pro­tec­tion and digital trans­ac­tions can be managed without cen­tral­ized au­thor­i­ties.

What’s the dif­fer­ence between tra­di­tion­al domains and Web3 domains?

Unlike tra­di­tion­al domains, which are managed by cen­tral­ized reg­is­trars, Web3 domain names are stored on a blockchain. That elim­i­nates de­pen­den­cy on in­sti­tu­tions like ICANN and DENIC. Domain owners have full control of their domain and don’t need to pay yearly fees. While classic domains are primarily used for accessing cen­tral­ized websites, Web3 domains also offer features like direct linking with wallet addresses and support for de­cen­tral­ized ap­pli­ca­tions.

They also allow for the hosting of cen­sor­ship-resistant websites in peer-to-peer networks. Their de­cen­tral­ized nature protects against domain seizures and fa­cil­i­tates global trans­ac­tions. However, Web3 domains aren’t yet natively supported by all browsers, which limits their reach.

What are the most expensive Web3 domain names?

Web3 domain names are often expensive, as they are based on unique digital assets that are reg­is­tered as NFTs on a blockchain. Ad­di­tion­al­ly, they are per­ma­nent­ly owned by the buyer, without annual renewal fees, which increases their long-term value. Below we list the most expensive Web3 domain name purchases according to DotNames:

  1. paradigm.eth – $1,508,884
  2. 000.eth – $317,759
