  Introduction To Blockchain   " Understanding the bare-bones of the decentralized realm" Topics: What is Blockchain. Why do we need it in today's world. Peer-To-Peer networks (P2P) Importance of Verification and Transparency Hi, My name is Mubashir Ali Baig and this is my multi part series of understanding what blockchain is all about and what are some of the most important aspects that differentiate a decentralized network from the conventional centralized networks. I'll try my best to explain the above mentioned topics without going deep into the technical jargon.
