**macbudkowski.eth**: Bitcoin's version of L2Beat

**timdaub.eth**: Wild, and also kinda embarrassing. They're all side chains and for some reason the Internet computer is also listed as a BTC layer. Can someone explain why?

**naomiii.eth**: Afaik ICP has some tech that allows a ICP smart contract to hold a private key and read + write to Bitcoin. So I guess it's also some sort of "L2" depending on the definition. At least it's as much an L2 as these sidechains probably ^^
