BitVMX

A platform for Universal Computation on Bitcoin.

White paper:

[BitVMX @bitvmx]

BitVMX is turning Bitcoin into a verification layer for cross-chain computation.

Union Bridge is a glimpse of what becomes possible when Bitcoin can verify external state transitions in a trust-minimized way.

This is only the beginning.

BIG: Union Bridge is now live on Rootstock Testnet.

Built on @bitvmx, it replaces trusted intermediaries with cryptographic enforcement. Withdrawals verified and challenged directly on Bitcoin. No fixed signers. No committees.

"The point isn't that Union Bridge is invulnerable. It's that the attacks that have historically destroyed bridges, the majority trust failures, are no longer on the table," says @SDLerner, Co-founder and Scientific Advisor, @RootstockLabs.

This is an early, experimental release focused on validating core bridge flows and usability.
