Blockchain security protects networks from hacks, exploits, and fraudulent transactions, ensuring trust in decentralized systems. Cryptographic methods such as elliptic curve cryptography (ECC), multi-party computation (MPC), and homomorphic encryption strengthen security. Smart contract auditing firms like CertiK and Quantstamp analyze vulnerabilities in DeFi protocols, NFT platforms, and Layer 2 scaling solutions. Security measures include cold storage for crypto assets, multi-signature authentication, and decentralized key management. The rise of post-quantum cryptography, bug bounty programs, and AI-driven threat detection enhances Web3 cybersecurity resilience.
