Using Bitcoinj java library to build your own wallet platform

Introduction

Bitcoin is so ubiquitous and has become part of the global economy. What Satoshi Nakamoto (father of Bitcoin) started many years ago has blossomed into an alternative to fiat money. His quest to create a cryptocurrency powered global economy as alternative to the centralised system of monetary control by governments has progressed significantly. From a developer’s point of view, we are always fascinated by Bitcoin and other cryptocurrencies that followed Bitcoin. Understanding how it works, the intricacies would feel much as home if we know how to implement basic concepts of cryptocurrency. In this tutorial, I would focus on Bitcoin.

If you are as curious as I am, hopefully you have read Satochi’s whitepaper and have used a wallet app like Trust Wallet and/or used an exchange app like Binance or Skrill or Cex.io. What we will learn here will make you appreciate the ground breaking invention from a granular perspective and you may even explore ahead to utilise the knowledge for greater things.
