Wamu

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

Cost-Effective

Threshold signatures are computed off-chain, so access-structure/security policy updates are free. Additionally, transactions are the same size, 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.
