Broad compatibility

The leading architecture of .bit makes it possible for you to set .bit alias for the following data:
1. Normal addresses of any public chain;
2. Contract addresses of EVM compatible chain;
3. Public keys of any asymmetric cryptography system.


When you set a .bit alias for normal addresses/public keys/contract addresses, you have to provide the corresponding private key. This means the only person who can set a .bit alias for the data is the person who owns the data.
