Crypto security refers to the measures, technologies, and practices used to protect digital assets (such as cryptocurrencies, tokens, or blockchain-based data) from theft, loss, fraud, and unauthorized access. It encompasses both the security of cryptographic systems—like encryption, private keys, and wallets—and the broader ecosystem involving exchanges, smart contracts, and user authentication. The goal of crypto security is to ensure integrity, confidentiality, and availability of digital assets and data in decentralized networks.
