نظرة عامة
Blockchain is considered highly secure due to its decentralized structure, cryptographic protocols, and consensus mechanisms. However, like any technology, it has potential vulnerabilities that developers and users must address.
Security Strengths
- Immutability: Data on the blockchain cannot be altered retroactively
- Cryptography: Ensures secure transactions and identity protection
- Decentralization: Eliminates single points of failure
- Transparency: Public ledger allows verifiable audit trails
Common Risks
- Smart Contract Bugs: Logic errors can be exploited
- Private Key Exposure: Loss or theft compromises user accounts
- 51% Attacks: Control of majority computing power can rewrite data
- Phishing and Social Engineering: Human error remains a threat
Best Practices
- Conduct third-party audits for smart contracts
- Educate users on private key security
- Use hardware wallets and multifactor authentication
- Choose reputable blockchains with strong governance
