Toshi's Treasure

This is about a particular weakness of the Shamir’s secret sharing scheme. During the share reassembly process, Shamir’s secret sharing does not provide a way to verify the correctness of each share being used. Verifiable secret sharing aims to verify that shareholders are honest and not submitting fake shares. The basis of Shamir’s secret sharing is on Lagrange basis polynomials. My solution is based on the computationally efficient approach of the scheme....
