Ika

Ika is a decentralized infrastructure designed to enable secure, low-latency interoperability between blockchains. It operates a distributed network of signers that use a cryptographic protocol called 2PC-MPC (Two-Party Computation and Multi-Party Computation) to jointly manage cryptographic keys without reconstructing them at any point. Through this method, Ika provides the ability to sign transactions across multiple blockchains while maintaining the security assumptions of decentralized systems. It leverages a DAG-based Byzantine Fault Tolerant consensus protocol (Mysticeti) for communication among nodes, ensuring efficient and scalable coordination of operations across the network. Ika's architecture eliminates reliance on trusted intermediaries and supports asynchronous, fault-tolerant transaction processing.
