Achieving the Security in Cyber World through Blockchain: A Taxonomy

The foundation of the blockchain is the concept of cryptography. We offer trustful and safe decentralized solutions. Numerous recent publications examine blockchain's applications in fields like consensus building, business finance, healthcare, information security, legal and the internet of things. Other analysis investigates the cryptographical principles behind blockchain. In the blockchain industry, technology of digital encryption is essential. Blockchain technology's development is both aided and hampered by the progress of cryptography technology. Although several recent studies examine block chain's applications in various industries, includes finance, health care, legal relations, Internet of Things, informational security, and consensus-building systems, just a handful have been published, only a few studies examine the blockchain's cryptographic principles. The infrastructure of blockchain is described in this paper, which includes data, network, consensus, contract, and application levels. The Author will also study its underlying fundamentals of cryptography and cryptographic concepts.
