Custody and wallet

Cryptography.

Core cryptographic primitives. Hybrid post-quantum across signatures (Ed25519+ML-DSA-65) and KEM (X25519+ML-KEM-768).

STATUS: Testnet
CRATE: tenzro-crypto
STABILITY: Stable
TYPE: Reference

Classical primitives

Signatures   Ed25519, Secp256k1
Hash         SHA-256, Keccak-256
AEAD         AES-256-GCM
KEX          X25519
Pairing      BLS12-381 via blst
KDF          Argon2id, HKDF-SHA256

Hybrid PQ

PQ migration in flight. Wallet, signing, and key agreement run hybrid composites (classical + PQ). Both legs must validate.

MPC

Threshold signature generation with key shares, partial signatures, and combination. Shamir SSS over GF(256).

VRF

RFC 9381 ECVRF-EDWARDS25519-SHA512-TAI in tenzro_crypto::vrf. Reuses Ed25519 validator keys.
