What Is the Bitcoin Name Service?
Bitcoin Name Service (BNS) is a decentralized naming system built on the Bitcoin blockchain, offering human-readable .btc domains for Web3 wallets. It simplifies crypto transactions by replacing complex wallet addresses with memorable names like unchained.btc.
Key features of BNS:
- Decentralized: Operates via Stacks smart contracts, leveraging Bitcoin’s security.
- Universal: Each domain is unique, human-readable, and permanently owned.
- Interoperable: Supports STX tokens, NFTs, and Decentralized Identifiers (DIDs).
Unlike traditional DNS, BNS eliminates central authority, ensuring censorship resistance and user control.
How Do .BTC Domains Work?
.BTC domains function as blockchain-based NFTs registered on Bitcoin via Stacks. The hierarchy includes:
- Namespaces: Top-level categories (e.g.,
.btc). - BNS Names: On-chain registrations (e.g.,
example.btc). - Subdomains: Off-chain records with separate keys (e.g.,
sub.example.btc).
Registration Process:
- Domains are minted via Stacks smart contracts.
- Ownership hashes are stored on Bitcoin.
- Clarity smart contracts ensure global synchronization.
