In this article, John Agbanusi explains how you can build a Node.js API from scratch by building and deploying an Ethereum Blockchain for decentralization. He also shows you a step-by-step process of integrating both the API and blockchain into a single API called a “decentralized application API”.
Blockchain technology has been on the rise in the past ten years, and has brought a good number of products and platforms to life such as Chainalysis (finance tech), Burstiq (health-tech), Filament (IoT), Opus (music streaming) and Ocular (cybersecurity).
From these examples, we can see that blockchain cuts across many products and use cases — making it very essential and useful. In fintech (finance tech), it’s used as decentralized ledgers for security and transparency in places like Chain, Chainalysis, and is also useful in health tech for the security of sensitive health data in Burstiq and Robomed — not to forget media tech such as Opus and Audius that also use blockchain for royalties transparency and thus get full royalties.
