Decentralized Name Services: A Case Study of ENS, BNS, & Unstoppable Domains

About Decentralized Name Services

Decentralized name services are simplifying access and functions in web3. Just like traditional domain name servers (DNS), decentralized name services provide human-readable names such as ‘alice.eth’ pointing to machine-readable identifier such as Ethereum addresses or addresses of different blockchains. Among the different name services, Ethereum Name Service (ENS) was the first decentralized name service on Ethereum, allowing users to link wallet addresses, social accounts or Web2 DNS to their ENS handles. On the other hand, Unstoppable Domains offers more variation of decentralized domains and their partnerships with numerous dApps increase utilities of their decentralized domains. Binance Name Service (BNS) aims to build a brand-new platform to link every user in the Web3 world so that BNB chain users can become the new growth engine of Web3, and beneficiaries. Decentralized name services are challenging traditional DNS in Web2 through innovative utilities and Web3 accessibilities.

More about BNS


The rise of various different decentralized name services on different decentralized networks like ENS, Unstoppable Domains, and BNS has led to fragmented user experiences and challenges in content interoperability. RSS3, as the largest Open Information indexer, aggregated these fragmented decentralized name services into one RSS3 Network, enabling seamless content access and sharing across platforms. This unified approach enhanced user experiences, simplifies developer integrations, and promotes a collaborative, interoperable Open Web ecosystem.

Build Multi-Chain Explorer with RSS3


While the rise of decentralized name services like ENS, Unstoppable Domains, and BNS brings easier access to decentralized applications through human-readable domains, users and developers faced the challenge of navigating and integrating content across multiple decentralized networks because of the fragmented networks and numerous different decentralized name services.


  1. Fragmented Name Services: With multiple decentralized name services in play across numerous decentralized networks, users found it challenging to keep track of their different decentralized domains across different networks.
  2. Lack of Interoperability: Each name service, be it ENS, Unstoppable Domains, or BNS, operated in its silo when they are in different networks. This lack of interoperability hindered users from seamlessly accessing and sharing content across platforms.
  3. Developer Hurdles: For developers, the challenge was twofold: ensuring accurate content retrieval across platforms and integrating multiple name services into a single application.

Solution: RSS3 Search

  1. One-Stop Indexing: RSS3 emerged as the largest decentralized name service indexer, supporting a wide range of decentralized name services, including ENS, Unstoppable, and BNS. RSS3 brought interoperability to the forefront, acting as a bridge between various decentralized name services.
  2. Look Up Domain Content: Through the RSS3 Search API, builders could effortlessly find on-chain activities of different name services across different decentralized networks and blockchains, ensuring accuracy and ease.
  3. Multi-Chain Name Services: RSS3 allowed users and developers to catch up with on-chain activities across multiple blockchains through various different name services.
  4. Unlocking the Open Web's Potential: With RSS3, users could explore seamlessly across the Open Web, searching different name services across different blockchains to view complete activities.


  1. Enhanced User Experience: Users could now seamlessly navigate their on-chain activities utilizing ENS, Unstoppable Domains, BNS, and more, all from a single interface.
  2. Boosted Developer Productivity: Developers benefited from a streamlined process, integrating multiple name services into their applications with ease.
  3. Promotion of Interoperability: RSS3's support fostered a interoperative environment among decentralized name services, even among different blockchains and decentralized networks.
  4. Growth in Adoption: With the challenges of fragmentation and interoperability addressed, more users and developers are drawn to decentralized name services, further strengthening the Open Web ecosystem.

In conclusion, RSS3's support for decentralized name services across different blockchains like ENS, Unstoppable Domains, and BNS showcased a mutually beneficial solution. It not only enhanced the user and developer experience but also realized the vision of a more unified and interoperable Open Web.
