Applied Cryptography

Understands applied cryptography fundamentals for blockchain: hash functions (SHA-256, Keccak), digital signatures (ECDSA, EdDSA), and key derivation (BIP-32/39). Follows team patterns for wallet integration and transaction signing.

Understands applied cryptography for smart contracts: hash commitments, signature verification (ecrecover), and Merkle proof validation. Follows team patterns for implementing commit-reveal schemes and signature-based authorization.
