Applied Cryptography

Understands hash functions (SHA-256, Keccak-256), digital signatures (ECDSA, EdDSA), and key derivation (BIP-32/39). Uses cryptographic libraries for message signing and verification.

Applies Merkle proofs for blockchain data verification. Implements commitment schemes and VRF for on-chain randomness. Integrates BLS signatures for aggregation in validator networks.

Designs cryptographic protocols for blockchain infrastructure: threshold signatures, MPC key management, zk-proof generation. Audits cryptographic primitives in blockchain protocols.

Defines cryptographic standards for the blockchain organization. Evaluates post-quantum cryptography readiness. Mentors engineers on applied cryptography and establishes security guidelines.

Researches advanced cryptographic schemes for blockchain: MPC, FHE, verifiable delay functions. Shapes long-term strategy for post-quantum algorithm transition for enterprise platform.
