 Verifiable secret sharing

Verifiable Secret Sharing (VSS) is a cryptographic method used for distributing a secret among multiple participants (or "shareholders") in such a way that: 1. **The secret can be reconstructed**: A certain number of participants, known as the threshold, must come together to reconstruct the original secret. 2. **The shares are correct**: Each participant receives a share of the secret, and they can verify that their share is correct without needing access to the secret itself.
