In open beta will radix have the built in app support? If so I have a few questions: 1) I am guessing that if the app can send radix to users, that would require a external request to the apps server correct? any chance for a example on how one would do it (for a minimal example, just a box with radix public key and then next box containing how many to send. then when a button is click a ssl supported connection is made, a php example of getting the request and sending to the local radix wallet would be awesome) 2) There will be a decentralized database correct? need examples for that too if possible 3) Are he examples and documentation found on this forum still valid?
