description: |
  - Implemented advanced Zero-Knowledge Proof (ZKP) systems, including Bulletproofs (Range Proofs and Inner Product Proofs) and cryptographic accumulators, leveraging the Fiat-Shamir heuristic for efficient, non-interactive verification.
  - Designed Multi-Party Computation (MPC) and Distributed Key Generation (DKG) protocols, enabling decentralized infrastructure through Threshold ECDSA/Ed25519, FROST, and Gennaro signature schemes without single points of failure.
  - Engineered highly secure, constant-time elliptic curve arithmetic across multiple standards (secp256k1, Ed25519, BLS12-381, NIST P-Curves), strictly enforcing safeguards against side-channel timing attacks, signature malleability, and nonce reuse.
  - Hardened system security by integrating AES-GCM authenticated encryption and Argon2id memory-hard key derivation, backed by an exhaustive suite of automated security tests, race-condition checks, and performance benchmarks.
