Estonian e-Residency and user authentication

[Samupaha]

I'm subscribed to Estonian e-Residency email list. A few days ago came an email that listed some ways how developers can use the system. One example was:

"Blockchain services can benefit from government verified clients: When users authenticate themselves via e-Residency’s government issued digital IDs, blockchain-based services gain new legitimacy. For example, on Stampery you can certify and authenticate documents and protect your intellectual property with e-Residency."

It'd be really great if @ccedk (and other fiat-gateways in the future) used this. After implementation there would be lots of potential customers who can easily verify themselves for fiat currencies. E-Residents can also open an Estonian bank account, which is in SEPA-area so they can deposit and withdraw funds fast to and from the gateway.
