BRC-20 White paper
BRC-20 Name Service is a domain system that seeks to decentralize and extend Web3 based on the Bitcoin BRC-20 Chain.
As the owner of a domain, you can configure and handle subdomains as you desired.
Your fully independent and extended domain (e.g. fan. BRC) can map identifiers from BRC-20 addresses, Dapp Content, and other data.
The BRC-20 Name Service (abbreviated as BTNS) provides a service that makes it easy for anyone to build a Web3 ID.
