Module scheme 

Signing scheme implementations for aggregation.

This module provides protocol-specific wrappers around the generic signing schemes in commonware_cryptography::certificate. Each wrapper binds the scheme’s subject type to Item, which represents the data being aggregated and signed.

Available Schemes

• ed25519: Attributable signatures with individual verification. HSM-friendly, no trusted setup required.
• secp256r1: Attributable signatures with individual verification. HSM-friendly, no trusted setup required.
• bls12381_multisig: Attributable signatures with aggregated verification. Compact certificates while preserving attribution.
• bls12381_threshold: Non-attributable threshold signatures. Constant-size certificates regardless of committee size.
