Addendum, there is block confirmation, but we will implement instant trading in other ways. (Our goal is a decentralised instantly tradable coin)
The implementation method and security are still being validated, and the reason for coming to the survey is also to confirm whether the market needs instantly tradable blockchain coins.
Decentralized and then instant doesn't sound believable. Can you assure users that there are no point of attack like hosting the network on centralized servers? Security is going to be a huge factor here and you'll probably have to invest a lot on that. Don't pursue this if you don't have huge private backing and are only expecting community support from token sale or whatever public crowdfunding. We are probably at a stage now where "instant" is no longer an effective marketing tool and people may no longer buy into that since there are already a plethora of chains offering fast or instant transactions.
