Cybersecurity in Blockchain
Also known as: Blockchain Security, Smart Contract Security, Crypto Cyber Defense
The practices and protocols used to protect blockchain systems from digital threats, attacks, and vulnerabilities.
Cybersecurity in blockchain refers to the array of techniques, tools, and frameworks employed to protect blockchain networks, smart contracts, wallets, and users from malicious activity. While blockchains are inherently secure due to cryptographic design, they are not immune to attacks. Threats include 51% attacks, smart contract exploits, phishing, front-running, and malware. Best practices include regular audits, penetration testing, multi-signature authorization, and user education. Projects also employ bug bounties, secure development lifecycles, and formal verification to enhance security across decentralized systems.
