Advanced Encryption Standard (AES)
Also known as: AES, Symmetric Encryption, AES-256
A widely used symmetric encryption algorithm adopted by blockchain platforms for secure data protection.

The Advanced Encryption Standard (AES) is a symmetric key encryption algorithm recognized globally for its speed, security, and efficiency. Standardized by NIST, AES encrypts data in fixed-size blocks using 128, 192, or 256-bit keys. While blockchains rely primarily on asymmetric cryptography, AES is commonly used in off-chain secure storage, wallet encryption, and encrypted messaging protocols. Its fast performance makes it ideal for devices with constrained resources. Though not natively part of blockchain consensus, AES plays a critical role in safeguarding sensitive data across decentralized applications.
