ENS (Ethereum Name Service) was launched in May 2017. Any user can register an Ethereum domain name ending in “.eth”. Currently, ENS is compatible with all DNS domain names. For example, domain names such as .com can also be used on ENS.
As an application representative in the field of Web 3.0, how should ENS understand the value of ENS? In addition to ENS on Ethereum, what other similar projects are there on other public chains?
After the ENS airdrop, many people began to target domain name services on other public chains. Guessing whether it will also bring an airdrop feast, so next we will take stock of other domain name projects on different public chains.
Nervos: DAS .bit
The full name of DAS is Decentralized Account Systems, which is a set of domain name services based on the POW public chain Nervos.
DAS provides a symbolic naming system ending with “.bit”. Like the domain name on the chain, it can be a website domain name or a wallet account on the chain. Currently, DAS account registration with ETH/TRX address is supported. According to official website information, in theory, DAS can use any public chain address for registration in the future. Currently, the DAS team is deploying other public chain signature algorithms to Nervos to support more public chain addresses to register for DAS.
In terms of names, DAS domain names can be registered in multiple languages around the world and even Emoji. Domain name registration is charged annually, at USD 5 per year, with a maximum period of 20 years. A storage deposit of approximately USD 5 is also required for the first registration. In terms of domain name length, domain names with a length of 1-3 characters have not yet been opened, 35% of domain names with a length of 4-9 characters have been opened, and all domain names with a length of 10 characters or more have been released.
Solana: SNS .sol
The domain name project on Solana was developed by the Bonfida team. Bonfida is the infrastructure development team on the Solana chain, providing a domain name system ending in “.sol”.
SNS domain name registration adopts an auction model. All auctions are publicly conducted on the official website of the domain name registration. The auction will last for seven days. In addition, there is no concept of renewal for SNS domain names, and the purchase is a permanent domain name.
Currently, SNS domain names support binding to Twitter accounts, and you can directly use the “.sol” domain name or Twitter account to send SPL native tokens, but there are not many wallets that support this function, only the sollet.io wallet supports. In addition, SNS domain names also support the construction of their own sub-domain names. Just search for relevant sub-domain names under your main domain name to activate.
Flow: Flowns .fn
Flown is a decentralized domain name service built on the Flow public chain. Last month, registration was officially opened on the Mynft platform. Flowns defines an open protocol for data and assets, allowing any form of resource/asset nesting. Domain name assets become meta-assets that are jointly defined by users and developers.
In the domain name service developed by Flowns, the top-level domain name is in the form of “.fn”. Currently, domain names with a length of less than 5 characters are not yet open. The rent for other domain names is from 0.32Flow to 40Flow for one year, and the specific price depends on the length of the domain name. The domain name is renewed annually. Before the domain name expires, the domain name resources will not be recycled, but will be marked as disabled and registrable in the Flowns service. Once a new user has registered an expired and unrenewed domain name, Flowns will cast a new domain name NFT for the newly registered user.
Terra: TNS .ust
TNS is the domain name service on the Terra chain, and the top-level domain name is in the form of “.ust”. The domain name function is similar to other domain names on the chain. TNS allows other data to be set, such as NFT, email, Twitter account, etc. So in addition to the wallet on the chain, TNS can also be regarded as a personal data on the chain.
The registration fee rules and prices for domain names are as follows:
- Domain names with 5 characters or more: 16 UST/year.
- 4-character domain name: 60 UST/year.
- 3-character domain name: 640 per year.
- The official said that it is currently considering placing the domain name on Terra native NFT markets such as Knowhere and randomearth for trading.
CELO .nom
The format of the top-level domain name on the public chain CELO is “.nom”, which supports numbers, letters and some special characters. Unlike other domain names, which charge different fees according to length, “.nom” domain names are fixed at 5 cUSD/year. Except for some reserved domain names, all domain names with a length of characters are open for registration.
Tezos .tez
The format of the top-level domain name on the Tezos chain is “.tez”. The domain name registration mode is similar to that on Solana. It is a bidding mode, and the higher price is awarded, but it is not a permanent domain name. After the domain name is obtained through bidding, standard pricing will be used for renewal and annual renewal fees will be applied. Domain registration only supports letters and numbers, and Tezos also supports subdomains.
The annual renewal price of a domain name depends on the length of the domain name:
- The annual fee for a domain name of five characters or more is 1tez.
- A four-character domain name costs 25tez per year.
- A three-character domain name costs 100tez per year.
Top bidding domains
Unstoppabe
The blockchain domain name service provider Unstoppable supports a variety of different forms of top-level domain registration. All registered domain names are permanent domain names. There are ten types of top-level domain names, namely: .crypto/.zil/.coin/.wallet/.bitcoin/. DAO/.nft/.x/.888/.bitcoin/.blockchain.
- The “.crypto” domain name smart contract is based on the ERC-721 standard protocol and belongs to the first domain name launched by Unstoppable
- The “.zil” domain name is a domain name service system based on the Zilliqa public chain
- “.Blockchain” is a domain name launched in cooperation with the wallet and block data service provider blockchain
- “.Nft” domain name comes from the cooperation with Opera browser
- “.Coin” comes from a collaboration with USDC issuer Circle
Currently, Unstoppable has integrated multiple wallets and applications, such as Coinbase Wallet, Chainlink, OpenSea, etc. It is the domain name system second only to ENS. In addition, Unstoppable is seeking to cooperate with Polygon to transfer domain name registration to the second floor.
In terms of domain names, except for domain names with a character length of 1-3 that are under protection, most domain names are already open (except for special words and combinations), but only the registration of letters and numbers is supported. The price of a 4-character domain name varies from US$800 to US$6000 depending on the format. With the same character length, the top-level domain names in the form of “.x” are the most expensive.
Handshake
Compared with the above projects, Handshake is a public chain that focuses on decentralized domain name registration, authentication, transaction and resolution. Their vision is ambitious, namely to create an alternative to the existing ICANN organization.
The Handshake chain uses the POW consensus, the specific algorithm is SHA3, and the Bitcoin-NG technology is used to improve TPS, but at the expense of security, it can only resist 1/4 of the computing power attack. Handshake still uses the traditional DNS, but changes the storage and management methods, using blockchain technology to decentralize, mainly for the root domain name.
FIO Protocol
FIO is a Delegated Proof of Stake (DPoS) blockchain. FIO Protocol is a decentralized domain name service. It is mainly oriented to wallets, exchanges, encrypted payments and other fields. It is integrated into existing products as an availability layer by providing a service layer related to other blockchain transaction data and confirmation.
The FIO protocol does not compete with or interfere with any other blockchains. It is more like a service provider’s role. For example, in the edge wallet, FIO Protocol supports the creation of “.dege domain names”. At present, wallets and applications such as ShapeShift, AscendEX, Guarda Wallet, etc., with the support of FIO Protocol, can create domain names with their own application characteristics. In addition, there is an annual fee concept on the FIO chain. At present, users need to pay 40FIO before they can use on-chain transfer and interaction.
In addition to the aforementioned domain name projects, there are also more public chains that are launching their own domain name service systems. For example, on November 2, Avvy Domains, the domain name service provider on Avalanche, officially reached a cooperation with Avalanche to build a domain name system in the form of “.avax”.
At present, domain names on the chain are still in the early stages of development, and truly decentralized websites have not appeared. But as a bridge between web 2.0 and 3.0, this is also a track that deserves long-term attention.
