Cryptography
provides the backbone for its security and trust mechanism. Secure
communications and ensuring that information is only accessible to intended
recipients.
Cryptography is the practice and study of techniques for secure communication in the presence of third parties. It enables individuals to securely transmit and store data so that only authorized parties can access it.
Cryptography plays a crucial role in blockchain technology by ensuring the security and integrity of transactions and data stored on the blockchain. It enables participants to securely interact with the blockchain network without the need for a trusted central authority.
Common cryptographic techniques used in blockchain include hashing functions (such as SHA-256), digital signatures (like ECDSA), symmetric and asymmetric encryption algorithms, and Merkle trees.
