Blockchain

Blockchain is a revolutionary technology that enables peer-to-peer transfer of digital assets without any intermediaries, and is predicted to be just as impactful as the Internet. Blockchains are best known for their crucial role in cryptocurrency systems, such as Bitcoin, for maintaining a secure and decentralized record of transactions. Sounds exciting? Read along to get started.

Introduction

Start with the Blockchain Specialization course on Coursera by the University at Buffalo and The State University of New York.

This 4-course specialization will help you understand foundational blockchain concepts, design and implement smart contracts, develop decentralized applications on the blockchain, and learn about the ongoing specific industry-wide blockchain frameworks.

Focus on the following:

  • Understanding the basics of blockchain technology

  • Key features of blockchain

  • Hashing algorithms and their role in blockchain security

  • Distributed peer-to-peer networks and their role in blockchain

  • Mining and Consensus Protocols

  • Overview of different types of blockchain

Bitcoin

Bitcoin was the first cryptocurrency created and is now the most traded and well-known.

  • The Bitcoin Whitepaper is the original thesis paper written under the pseudonym Satoshi Nakamoto on October 31, 2008 that set the basic structure of the Bitcoin network.

  • Refer to this video by 3blue1brown: But how does bitcoin actually work?

  • PRDV151: Bitcoin for Everybody & CS120: Bitcoin for Developers I by Saylor Academy provide the foundations necessary for understanding, working with, and building on Bitcoin and other open cryptocurrency systems. Focus on:

    • Bitcoin's monetary policy
