Bitcoin Name Service (BNS) offers a human-readable naming system for Web3 wallets, simplifying the user experience in the Bitcoin ecosystem. By linking complex alphanumeric wallet addresses to memorable names, BNS enhances usability and reduces errors in transactions. This guide explores how BNS works, the functionality of .BTC domains, and the steps to acquire one.
What Is Bitcoin Name Service?
Bitcoin Name Service is a decentralized naming database secured on the Bitcoin blockchain, providing registered Web3 usernames through Stacks. It acts as a Web3 phone directory, mapping human-readable hostnames like .BTC to cumbersome wallet addresses.
Similar to the Web2 Domain Name System (DNS), BNS offers an interface for buying, registering, managing, and searching domain names. However, while DNS relies on centralized servers, BNS operates on peer-to-peer systems that are secure and censorship-resistant.
BNS names possess three key properties:
- Universally unique
- Human-meaningful
- Strongly owned
Leveraging Bitcoin’s security and resilience, BNS enables seamless user experiences within the Stacks ecosystem. Users can send and receive STX, Stacked-based tokens, and NFTs using these readable names.
How Do .BTC Domains Work?
A .BTC domain is a blockchain-based name registered and stored as an NFT on the Bitcoin network. These domains are managed by BNS and registered via a smart contract on Stacks, utilizing Bitcoin’s security features and the Clarity smart contract language to maintain a decentralized naming system.
Each .BTC domain’s ownership is documented as a hash on the Bitcoin blockchain. Domains and subdomains feature Decentralized Identifiers (DIDs), providing permanent identifiers for public keys and compatibility with other DID-based systems.
The BNS naming hierarchy consists of three layers:
- Namespaces: Similar to DNS top-level domains, these are top-tier names anyone can create but not own.
- BNS Names: Registered directly on the blockchain, requiring an existing namespace for creation.
- BNS Subdomains: Stored off-chain and owned by independent private keys.
Registration involves a transaction with the BNS smart contract on Stacks, ensuring global synchronization and replication across all nodes.
Steps to Purchase a .BTC Domain
To acquire a .BTC domain, you’ll need a compatible wallet like Hiro Wallet or Xverse and STX tokens to cover registration costs. New domains cost 2 STX (excluding transaction fees). STX can be purchased on exchanges and transferred to your Stacks-supported wallet.
Search for Your .BTC Name
Visit the BNS platform and enter your desired name in the search bar. The system will indicate availability, fees in STX, and registration duration (e.g., 5 years for 2 STX).
Create an Account
Confirm name availability and create a Stacks account linked to Bitcoin. Connect your Stacks-compatible wallet to the site to log in.
Complete Your Purchase
After logging in, you’ll receive a prompt to buy the selected .BTC domain. Submit 2 STX, and you’ll own the domain for five years. A small gas fee applies. Once the transaction confirms, the domain appears in your Stacks wallet.
Alternatively, you can purchase pre-owned .BTC domains on secondary markets. BNS names grant unique Web3 identities and streamline error-free transactions.

Frequently Asked Questions
What is the difference between BNS and DNS?
BNS is decentralized and blockchain-based, while DNS relies on centralized servers. BNS offers stronger ownership and censorship resistance, ideal for Web3 applications.
Can I transfer my .BTC domain to another wallet?
Yes, .BTC domains are transferable between wallets supporting the BNS standard. Ensure the recipient’s wallet is compatible before initiating the transfer.
How long does a .BTC domain registration last?
Initial registration typically spans five years. Renewals require additional STX payments, similar to the initial process.
Are .BTC domains compatible with all wallets?
No, only wallets supporting Stacks and BNS can manage .BTC domains. Popular options include Hiro Wallet and Xverse.
What happens if I lose access to my wallet?
Since domains are tied to private keys, losing wallet access may result in permanent loss of the domain. Always backup your wallet securely.
Can I create subdomains with my .BTC domain?
Yes, BNS supports subdomain creation, allowing you to assign memorable addresses for specific purposes or users.
