You’ve heard of bitcoin. It’s a form of digital cash you can send to anyone, even a complete stranger. You may not have heard about bitcoin’s digital ledger, called the blockchain, which tracks and validates bitcoin transactions. Blockchain technology has enormous potential beyond bitcoin to automate every type of online transaction that requires a degree of trust. In this short video, produced by Institute for the Future, Olivia Olson (the voice of Marceline the Vampire Queen in Adventure Time) explains how blockchain technology can be used to launch companies that are entirely run by algorithms, make self-driving cars safer, help people manage and protect their online identities, and track the billions of devices on the Internet of Things.
