The document discusses blockchain technology and its potential uses. It provides an overview of how blockchain works as a distributed database with synchronized records across networks and different access levels. It then discusses several potential applications for blockchain beyond just cryptocurrency, including for aid distribution, tracking diamonds, notarization of documents, verifying qualifications, and managing cooperatives. However, it also notes some pitfalls like scalability issues and hype cycles, as well as how organizational inertia and vulnerabilities could impact adoption.

Editor's Notes
- Physical access control to the database or the computers it’s stored on
- Physical access control to the database or the computers it’s stored on
- Let’s go back to thinking about the database itself
- What about backups? If you’re a responsible organisation, you’ll do backups
- Not just one, but loads
- Maybe you’ll even spread your backups all over the country!
