### Introduction

In this video, Bill will introduce the concepts of what a blockchain is, the benefits of a blockchain, and the network environment it operates in. Bill describes a blockchain as a single, append-only, transparent, publicly available and cryptographically auditable database. Blockchains operate using a peer to peer (p2p) network with no single node designated as the central authority. 

To better understand what all that means, Bill begins to work through a familiar problem of creating reproducible, durable, and secure builds that software teams face. It’s a real problem the Go team eventually solved with the new module system. As Bill uncovers different problems that present themselves, he introduces different blockchain concepts that can help provide a solution.
