WebJun 18, 2024 · Blockchain is a distributed ledger that uses hash functions to provide a unique fingerprint of every transaction, recording and authenticating them. When each transaction is signed and verified as unique, it’s sent to join a “block” of other transitions and becomes impossible to modify. These blocks together form the blockchain. WebA cryptographic algorithm is the mathematical equation used to scramble the plain text and make it unreadable. They are used for data encryption, authentication and digital signatures. There are three types of cryptography: Symmetric-key cryptography - Both sender and receiver share a single key and the sender uses this key to encrypt plaintext.
