Threshold Signature

The threshold signature (TSS) protocol is a cryptographic scheme that allows a group of participants to collectively sign a message or transaction without revealing their private keys to each other.

In a threshold signature scheme, the private key is split into several shares, each of which is distributed among the group of participants. To generate a signature, a minimum threshold of participants is required to combine their shares and produce a partial signature.

Threshold signature protocols are considered secure because they provide several security guarantees that protect against various types of attacks, such as the compromise of a single participant's private key or the collusion of a group of participants.

Our own Signer Service relies on the TSS protocol. This distributed trust model makes it difficult for any one participant or third-party service to compromise the system. Therefore, the Signer Service is reliable and trusted by our clients.
