The following details how MPC is utilized by Sygma.
Secure multi-party computation (MPC) represents a powerful next step in digital asset security because it eliminates the risks of a single point of compromise.
MPC was introduced as a solution for the Two Billionaires Problem (Bob and Alice; how to decide who is richer without showing their exact funds, a specific problem which is a Boolean predicate).
The multi-party computation (MPC) model that Sygma employs includes a number of trusted relayer nodes. These trusted relayer nodes will be run by reputable entities in the web3 space.
