We are on a mission to make it super easy to build with Bitcoin. Today, we are releasing Gateway. Gateway allows users to directly onboard to BOB with a single BTC transactions (into

⤷ Unlock use cases for your BTC across the BOB ecosystem

Yes, once BitVM works we can build Bitcoin rollups/1-of-m bridges.
No, your current zk rollup isn’t verified Bitcoin.
Everybody wants to build on Bitcoin.

I agree with you that the Solana bridge is right now centralized and many decided to go for multi-sig bridges.
But, it’s not correct that it’s impossible to build far better bridges. If you use a chain relay on both sides with permissionless relayers you only:
