Security of Communication Increase through Use of Combination of Cryptography and Blockchain technology. Abstract: The blockchain is an innovative technology. A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. Bitcoin is known as a cryptocurrency because it makes use of cryptography to implement a decentralized monetary system and enable fully digital peer-to-peer. Cryptography is an integral part of various consensus mechanisms in blockchain networks. Consensus algorithms like Proof-of-Work (PoW) and Proof. Cryptography is the science of how data or information is converted to a secret format to be transmitted securely between two parties.
