Blockchain for Real World Applications

We are in the midst of another big revolution called BLOCKCHAIN, a distributed database that maintains an ever-growing list of records, called blocks. This innovation landscape represents only 12 years of work by an elite group of geeks, cryptographers and mathematicians. In times to come, blockchain will permeate every human pursuit, making processes efficient and smart. As the full potential of these breakthroughs is realized in society, things will gradually begin to happen differently – international money transfers will be faster and more reliable; verification will be easy; identity will be global, decentralized; and no person - whether administrator, manager, industrialist, start-up, employer, service provider, educationist, student or user, will remain untouched. Obviously, the world will need to embrace this technology with open arms. In view of this, the author strongly believes that every section of the society should be made aware of blockchain, be it a budding technologist, a start-up enthusiast or a non-technical user of decentralized apps. This article, which has been extracted the Book, ‘Blockchain for Real World Applications, written by Rishabh Garg and published by John Wiley & Sons Inc. USA, provides an in-depth understanding on the blockchain ecosystem, architecture, Ethereum, Hyperledger and cryptocurrencies, followed by a comprehensive discussion on potential uses of blockchain such as cryptography, cyber-security, identity management, credential verification, job certification, healthcare, remote health monitoring, organ transplantation, genomics, pharmaceutical supply chain, food and civil supplies, etc. Live screen-shots and associated code-cells, provided in between the text, will help the readers to comprehend banking, business, decentralized finance, prediction market, portfolio management, quadratic funding, crowd funding, e-commerce etc. with a de novo approach. The content provides a practical step-wise mechanism for each reader to implement their own content-based storage system. Our approach is to help you operate this revolutionary technology by introducing you to its every detail. With this new technology under your control, you will be able to access the features of blockchain as easily as operating a simple mobile app. So, join the blockchain revolution; learn how to develop decentralized applications; and get ahead of your peers
