Blockchain can mean many things to many people. It is a set of protocols and encryption technologies for securely storing data on a distributed network for the developers. It is a distributed ledger for business and finance and the technology underlying the explosion of new digital currencies. For technologists, it is the driving force behind the next generation of the internet. On the other hand, it is a transformational technology facilitating large-scale human progress in previously unimagined ways for the rest of the people, a tool for radically reshaping society and economy. Some view it as a disruptive technology that can be the source of a great deal of fraud, illegal activity, where others see opportunities to bring into existing systems by providing decentralization, transparency, and efficiency. This complex technological, economic, and social phenomenon has been the subject of fervent debate. It calls into question what might have been seen to be established parameters of the modern world like currency, economics, trust, value, and exchange. It is a revolutionary new computing paradigm and one of the most significant, fundamental digital platforms’ advances since the internet. It is an emergent technology experiencing very rapid evolution, and so is our understanding of what it is and what it can be. This paper is subject to the use of Blockchain concepts in mobile networks to strengthen the Home Location Registry (HLR) database and make it decentralized for secure transactions and in banking and financial centers. Blockchain also holds potential implications for global commerce. It could make trade more efficient by removing the manual and paper-based processes and introducing streamlined and automated processes.
