What is the Threshold signature scheme(TSS)? Multi-party Computation(MPC) simplified

In our previous articles we have discussed Cryptography, Symmetric, Asymmetric encryption, and related things. In this edition, we will be deeply focusing on Threshold signature Schemes,  multi-signature and multi-party computations.  Let assume Bob has something secret in his account and needs to keep it secure. Now in scenario1, he put that into a digital vault, […]
