Mina

Mina is a blockchain protocol designed to be lightweight and accessible by maintaining a small, constant-sized blockchain—roughly the size of a few tweets—regardless of transaction volume. It achieves this through advanced cryptography called zero-knowledge proofs, which verify transactions without revealing details or requiring full data storage. This makes Mina highly decentralized, fast, and energy-efficient, as users can easily operate nodes on personal devices. Overall, Mina aims to improve blockchain scalability and privacy, enabling anyone to participate securely in decentralized applications without needing powerful hardware.
