Blockchain security covers Web3 / smart-contract auditing (mostly Ethereum EVM and Solidity, plus Vyper, Move, Cairo, Solana Rust), protocol-level attacks (consensus, MEV, bridges), wallet and key-management security, and cryptographic primitives (zero-knowledge, threshold signatures). Smart-contract auditing is one of the highest-paying specializations in security as of 2024-2026.
