While the media abounds with stories about the boom and bust cycle of bitcoin, most people don’t understand the basic principles of how cryptoassets like bitcoin work. This class explains the technologies “under the hood”, as well as relevant tools and the crypto ecosystem. Session 1 covers coin types, mining, forking, wallets, cryptography, blockchain basics and forensics, transactions, exchanges, airdrops, faucets, and security. Session 2 covers distinctions between public and private blockchains, enterprise blockchain platforms, macro data about blockchains, why banks have been forced into piloting blockchain en masse, why blockchain is such a powerful tool to solve economic challenges, and a sector-by-sector view of disruptive blockchain innovation. While the course avoids investment recommendations, it provides people with the conceptual and detailed knowledge required to understand how cryptoassets might affect them personally, as well as influence society at large.
