Far and Few Review on Blockchain Technology and Its Applications

Abstract

The word “Fad” has become a contagious with the advent of Blockchain technology where new currencies are sprouting from it, which affords preferable characteristics and features such as no intermediators, decentralization and smart contracts in which everyone knows about it, alongside, autonomy, verification, etc. The work, first accomplished the review about Blockchain itself, mainly its origin, structure of blockchain, types of blockchain with comparison with other features, uses of blockchain application in various fields, blockchain interoperability, use cases of blockchain, energy consumption, in-depth comparison of the blockchain protocols and the complete list of Block use cases. Additionally, the Blockchain security in the network particularly in internet (Web Attacks) is focused. To be precise, we reviewed and categorized various real time attacks based upon the Blockchain ecosystem. Lastly, the challenges and research trends of the blockchain are discussed which helps to achieve more and efficient blockchain ecosystem. The work will also exhibit the future direction and recommendations which will help out the budding researcher.
