Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

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 cryptocurrencies, 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.
