A protocol and library for computation of threshold signatures by multiple decentralized identities.


Threshold signatures are computed completely off-chain, so access-structure/security policy updates are free. Additionally, individual transactions are the same size (because they include only one jointly computed signature), and thus cost the same as those generated by traditional singe-party signers/wallets.

Universal Interoperability

Threshold signatures are similar to standard signatures generated by traditional signers/wallets. So they work everywhere traditional singe-party signatures work. No custom integrations and/or additional standards are required.

Enhanced Privacy and Security

Threshold signatures don't leak any information about the quorum structure/security policy, the identity, nor the number of approving signatories.
