Libra without the explicit coin

What is Revolut? 

It’s a debit account-app aimed at affluent people who travel, with services that undercut banks. For a monthly fee, Singaporean residents can open a debit account via their mobile, receive a Revolut card (plastic or metal), and use it to spend worldwide in Singaporean dollars or 12 other currencies. Revolut offers interbank rates for foreign exchange and free money withdrawals worldwide. In Europe, Revolut also offers free commissions on trading stocks or cryptocurrencies (like RobinHood in the U.S.).

Take Libra, throw away the coin and just have each app manage multiple currencies with a fair traded FX pit for exchange.  Revolt thus becomes a virtual digital coin in that in balance it acts as if there were a coin. In other words it is a trusted FX ledger with priced queues, but it is in and out in one transaction unlike bitcoin, which is in, then out at some asynchronous time later. With the efficient FX exchange they do not need a unique coin, but they cannot hedge the central banks with value storage.

Revolt requires smarts in the handheld and is limited to mobile devices. We need to upgrade the cart chip so folks can just get a smart credit card and do this. Apple? You listening?

Anyway, sandbox is being deployed at 'warp speed' as Jamie says.
