Leading Blockchain Domains Providers

What is a Blockchain Domain?

A blockchain domain is a domain name recorded on a blockchain instead of the traditional DNS, giving the owner direct control, resistant to censorship, and often used for decentralized websites and crypto payments. Only a few blockchains are technically suited for this use, mainly those that allow smart contracts.

Major Web3 Domains Players

The most widely used technology is ENS (Ethereum Name Service), with .eth domains that act as decentralized identifiers, replacing wallet addresses and integrating across the Ethereum ecosystem.

Unstoppable Domains is the second major player, offering multiple extensions across various blockchains. It has taken advantage of the hype surrounding cryptocurrencies and web3 to sell via aggressive marketing domain names with sparkling extensions such as .BITCOIN, .X, .CRYPTO, .NFT or .888, but not interoperable with the global DNS and which lack practical use.

Challengers in the blockchain domains sector include Space ID, which enables cross-chain domains like .bnb and .arb, sns.sol for Solana-based .sol domains, RNS on the Bitcoin sidechain RSK, Tezos domains for the Tezos blockchain, Peername, focusing on early or alternative blockchain naming systems and Orange Domains, a joint-venture including Tucows.

Other Blockchains designed for Web3 Domains

FIO Protocol is a decentralized identity project that allows users to create a single, human-readable FIO address (like jane@wallet) that links to all their crypto wallets.

XPR Network is a layer-one blockchain that offers fast, gas-free transactions, on-chain identity, and WebAssembly smart contracts.

First altcoin derived from Bitcoin, Namecoin functions as a decentralized key/value registry, with its main use case being the management of .bit domain names.

The Arweave Name System (ArNS) is a naming system on the Arweave blockchain.

Ucosystem-ucash is a blockchain-based venture with payment, identity, and application tools that run on its own infrastructure.

Top level Web3 Domains

Some Web3 providers allow users to create their own TLDs, especially Namebase and Bob Wallet, which operate on the Handshake blockchain, and Decentraweb, which provides Top-Level Web3 Domains on Ethereum. NameStone provides an API for seamless, gasless management and issuance of Ethereum Name Service (ENS) subdomains.

Many Web3 Domain providers enable the sale of both Web3 top-level domains and second-level domains. SPACE ID also offers this service on BNB Chain, Arbitrum, and Ethereum, as well as Freename and Pool Infinity Domains.

Web 2.5

Web 2.5 players intend to bridge the gap between Web2 and Web3 by tokenizing traditional DNS domains. The name keeps resolving via DNS, while an on chain token mirrors ownership to enable blockchain based custody and trading. A U.S.-based company founded by Fred Hsu in 2023, D3 Global is a pioneer in the Web 2.5 space. Thanks to partnerships with major blockchains and registrars and participation in nTLD ICANN round 2 in 2026, D3 plans to launch ICANN-approved, blockchain-native TLDs and build an on-chain marketplace for legacy Web2 domains.
Similar Web 2.5 projects, albeit on a smaller scale, are currently being carried out by start-ups such as 3DNS., NameFi, WebUnited and GBM Domains.
