Indeed the whitepaper is dated, and doesn't mention the ease of use we are currently building into the platform, nor other aspects like the weavechain for inter-blockchain swaps and escrow. We have more to add to it and make it up to date.
The GUI is currently in alpha testing, and there is still heavy lifting to be done before it can go beta. Our goal is to deliver a node that users can log in to from the web, and use cryptocurrencies from there, or - if they are more technical - host their own node at home and make the network stronger. And we have a strong focus on usability. There is still a lot of UX development to get there, and the challenge for us is to make sure the browser environment is as safe and secure as it is useful.
Excellent reply. Thank you very much.
