What Is a “Threshold Signature Scheme” (TSS) and How Is It Different from Multi-Sig?

TSS is a cryptographic technique that allows a group of participants to collectively sign a transaction without a single party ever having access to the full private key. Unlike multi-sig, which requires a predefined number of independent keys to sign, TSS generates a single, distributed private key.

This is more efficient on the blockchain and can offer greater security and flexibility.
