Common Blockchain Security Attacks and How They Work
Blockchain security attacks are attempts to manipulate blockchain networks, steal digital assets, disrupt transaction processing, exploit smart contracts, or deceive users. Although blockchain uses cryptography and distributed consensus to provide strong security, blockchain applications are not automatically immune to attacks.
Blockchain technology is designed around decentralization, cryptographic verification, distributed databases, and consensus mechanisms. These features make unauthorized modification of properly confirmed blockchain data difficult, but attackers can still target the network, consensus mechanism, smart contracts, wallets, applications, exchanges, or users.
Understanding common blockchain attacks is important for students, developers, blockchain administrators, cryptocurrency users, and cybersecurity professionals.
