Union's ZK interop moat: in-house prover Galois and relayer Voyager
Post64 words
Union is built around ZK aggregated cross-chain consensus proofs and runs its own prover (Galois) and relayer (Voyager), unlike peers that rely on third-party services. Argues that is a real technical moat.
Key claims
Union built its own prover Galois and relayer Voyager
Most interop competitors rely on third-party services
Many interop teams are looking to integrate ZK tech into their architectures nowadays.
What makes Union different?
It was purpose-built around cutting-edge ZK tech, powering aggregated cross-chain consensus proofs. An entirely permissionless, fully trust-minimized, and highly efficient system.
Union built its own prover (Galois) and relayer (Voyager), which means they have actual technical moat, whereas most peers/competitors rely entirely on third-party services.
