Crypto

Crypto encompasses cryptographic protocols, blockchain-based ledgers, and decentralized digital currencies. It relies on public-key cryptography, hash functions, and consensus mechanisms (like proof of work or proof of stake) to secure transactions and achieve trust without centralized authorities. Smart contracts enable programmable, self-executing agreements on blockchain networks, while wallets and keys manage ownership and access. Ongoing areas include scalability, interoperability, privacy, and security auditing to enable robust, permissionless financial and data ecosystems.
