While physical devices as in prices are a fresh touch on the crypto gaming, i don't think that is the best use case for smart contracts. I mean we still would need to trust you to post them and everything. It kinda defeats the purpose of automatic payments.
Also, your linkedin link is empty so are you seriously trying to pull this of as anonymous devs?
if I understand correctly, in this game all payments will work on smart contracts, and we do not need to trust anyone.
Did you even read my post or do you understand the point of smart contracts? I was talking about mailing physical prizes.
