First up, we see a short demo of the Calibra app running on iOS. The app looks very similar to other apps like PayPal and Venmo and Facebook will also embed its services into WhatsApp and Messenger. The most interesting thing? You won't need a Facebook account to use Libra.
Next up we have the Libra Ecosystem including a very simple description of blockchain technology. It's definitely a solid primer on what is actually a complex and difficult problem.
Still too complex? This very basic "Blockchain 101" post describes how Libra – and other blockchain-based – cryptocurrencies work.
Finally, we have a brief video about the Libra Association, a non-profit that will manage the cash associated with the project. Think of the Association as a group of non-profits who will aim their do-gooding at various global problems. In short, Facebook is hoping this project not only makes money but helps the unbanked.
