Shamir’s Secret Sharing for Spark Wallet

This module implements Shamir’s Secret Sharing (SSS) functionality for the Spark wallet. Shamir’s Secret Sharing is a cryptographic technique that allows a secret (such as a private key) to be divided into multiple parts (shares), where a specified threshold of shares is required to reconstruct the original secret.

In the Spark wallet, this capability supports:

• Social recovery of wallet keys
• Distributed custody arrangements
• Enhanced security through secret distribution

The implementation uses a verifiable variant of Shamir’s Secret Sharing, which allows participants to verify the validity of their shares without reconstructing the secret.
