Cryptography in Blockchain (Part 6- Blockchain Series)

WebA hash chain is similar to a blockchain, as they both utilize a cryptographic hash function for creating a link between two nodes. However, a blockchain (as used by Bitcoin and related systems) is generally intended to support distributed agreement around a public ledger (data), and incorporates a set of rules for encapsulation of data and ... WebBlockchain’s solution to the Byzantine generals’ problem is cryptography. A blockchain network uses cryptographic techniques at two levels that keep the data secure. One is the key-encryption method and another is hashing. Key encryption is a cryptographic method that ensures safe transmission of information from point A to point B.
