The Synapse network is secured by cross-chain multi-party computation (MPC) validators operating with threshold signature schemes (TSS). The network is leaderless, and maintains security by each validator running the same process upon receiving on-chain events on the various chains that the MPC validator group tracks. Once two-thirds of all validators have collectively signed the same transaction using their own individual key, the network achieves consensus and issues a transaction to the destination chain.
