A Threshold Signature Scheme (TSS) is a cryptographic method used to create digital signatures that require a group of participants to jointly produce a signature without needing any one individual to sign alone.In a TSS, a secret key is shared among a group of n participants, with the condition that only a subset, called a threshold, of these participants can combine their individual shares to create a valid signature. For example, in a 5-of-8 scheme, any 5 out of the 8 participants can collaborate to sign a transaction.This approach enhances security and decentralization. Since no single participant holds the entire key, the risk of key compromise is reduced. Additionally, it allows for greater flexibility in decision-making, as only a subset of trusted members can authorize transactions or actions.Threshold Signature Schemes are particularly useful for multi-signature wallets, where multiple approvals might be required to enhance security, as well as for distributed systems where trust is multifaceted.
