# Fairgate

Fairgate is a Bitcoin computation research and infrastructure company.
We created BitVMX, a framework for disputable off-chain computation anchored to Bitcoin,
and Bit2, a Bitcoin-native coordination and settlement layer for autonomous agents.

Our core research areas: BitVM, BitVM2, garbled circuits, RISC-V on Bitcoin,
zero-knowledge proofs on Bitcoin, trust-minimized bridges, multi-party computation (MPC),
and the emerging agentic economy on Bitcoin.
