Abstract
The advances in computer science & technology have gone to new levels.
The process of computational technology and ubiquitous computing is expanding
exponentially daily. The computer system & its related inventions have become an
integral part of our lives. People & services are migrating towards clouds and
decentralized platforms. Nowadays, commerce & finance on the Internet rely on trusted
third parties like banks to process electronic online payments. Though it fits well with
most transactions, it still suffers from the inherent weakness of trust-based models.
Blockchain Technology- the technology behind the cryptocurrency Bitcoin is buzzing a
lot nowadays to invent and witness the future of data storage & processing in an
efficient, decentralized, tamper-proof, and peer-to-peer (P2P) network. Nowadays, the
use of blockchain is not confined to crypto-currencies only. This revolutionary
technology is drawing its impact & use in many fields and applications. Primarily, a
blockchain network can be used for storing, sharing & transparently transferring data
without the intervention of third parties and other intermediaries. In a blockchain
network, blocks are added using a consensus algorithm & connected cryptographically.
Hence it is merely impossible to delete and modify the content of blocks stored in a
blockchain network. Other advantages of this technology include consistency, security,
transparency, distributed ledger, decentralized network, etc. This paper systematically
reviews the work accomplished by many researchers for the past 11 years. Specifically,
the application & impact of blockchain technology in various fields like crypto currencies, the health sector, e-governance, banking, finance, and food supply
management systems have been discussed, and a projection of a novel application of
the same technology has been proposed.
