Cryptography Essentials
Cryptography is the backbone of blockchain security. It ensures data integrity, privacy, and authenticity in decentralized systems.
Key Concepts
- Hash Functions: Convert data into a fixed-size string; used for block linking and data integrity.
- Public-Key Cryptography: Enables secure communication and digital identity.
- Digital Signatures: Prove ownership and authorize transactions.
Without cryptography, blockchains and Web3 applications would not be possible.
