Abstract
Blockchain is a technology that is decentralized. It has the ability to tackle a wide range of industrial issues. A blockchain transaction’s records are secured by cryptography, and each transaction is linked to previous transactions or records. Algorithms on the nodes validate blockchain transactions. As a final point, blockchains enable transparency, allowing each participant to keep track of transactions at any point in time. Smart contracts provide for safe transactions, reducing the risk of third-party interference. Readers will have a better understanding of how blockchain technology helps protect and manage today’s users. There is a thorough report on diverse blockchain studies and security proposed by the research community, and their distinct implications on blockchain, in the review. This article concludes with a detailed description of the blockchain security followed by a discussion of the many varieties of security enhancements.
