Ika: Fast, Decentralized and Secure Interoperability Powered by 2PC-MPC (PDF):

We propose Ika, a distributed system of MPC signers that can be used as a comprehensive solution to blockchain interoperability challenges through a Zero Trust cryptographic framework paired with an architecture optimized for performance and decentralization. Ika integrates the novel 2PC-MPC protocol, cutting-edge advancement in threshold cryptography, alongside state-of-the-art DAG-based Byzantine consensus protocol Mysticeti as the broadcast channel to achieve reliable broadcast. The system can enable secure, low-latency, and decentralized cross-chain interactions, and establish a new standard for blockchain interoperability.
