Hello everyone. I correctly understand that to finance other people's deposits can only be coins BERRY and no other currencies?
I think so, yes. As the whole platform is build around the token and this will be used for the normal payments too.
so it will reside in ethereum blockchain ?
Yes the information and rental contract will be stored in the ethereum blockchain
But this is already interesting. I would like to see an example of a saved lease in the blockchain ethereum, if at all possible. Maybe there in a smart contract can be stored some hash lease agreement, but in this I'm not sure. This question should be clarified from the developers.
In general, for such a function, you need to develop your own blockchain.
