Cobo MPC WaaS leverages cutting-edge secure Multi-Party Computation (MPC) technology to implement a Threshold Signature Scheme (TSS).
Using MPC-TSS technology, private key shares are created simultaneously by each party in a secure environment.
These parties can then jointly sign transactions without ever exposing their key shares or materialising a private key at any time.
As the private key that executes transactions never exists or lives in any devices - rather, it is a collectively generated value, the MPC-TSS setup removes any single point of failure, making key theft, internal fraud and collusion more challenging for bad actors. This design ensures no one party can unilaterally move funds.
