Bitcoin: Technology Videos

This short series explains how Bitcoin works from the ground up. You will learn about the tools that keep digital money secure, like hash functions and digital signatures. You will also see how transactions are recorded in a shared ledger called a blockchain, and how new bitcoins enter the money supply. It is a clear introduction to a technology that often shows up in the news. No special math background is needed, though curiosity about computers and money will help.
