What is Cryptography in Blockchain?

Cryptography plays a crucial role in blockchain technology by providing secure and tamper-resistant mechanisms for data encryption, authentication, and integrity verification. Cryptographic techniques such as hash functions, digital signatures, and public-key cryptography are used to ensure the confidentiality, authenticity, and immutability of transactions and data on the blockchain. By leveraging cryptography, blockchain networks like Cardano achieve trustless and decentralized consensus, enabling secure and transparent peer-to-peer transactions without the need for intermediaries.
