Nomad

Nomad is a security-first cross-chain messaging protocol that enables seamless communication between blockchains. By leveraging an optimistic mechanism, Nomad only requires one honest actor to keep the entire system safe. This drastically reduces the trust required relative to other interoperability solutions.
