Hi, i was wondering
Will your giftbox be visible and transferable via blockchain, or will buyers actually receive a physical box?
Why not send the buyers a physical coin

Yes, all bookings will be on the blockchain, since the giftbox is just a transferable booking it will also be on the blockchain - transferable just like a normal coin/token transaction.
In the first phase the giftbox will only be digital, because we have not yet found a truly safe/secure way of delivering a physical giftbox with its booking "intact". It is however on our to-do for the mid-to-long term future, because selling a physical box would allow us to gain additional exposure through retail stores.
Sincerely,
The Tryvium team
