This is an interesting idea! A couple pieces of feedback:
There are some typos in the blackpaper. (I like the idea of black, though!)
On Page 4, for example: In the case if double-spend attempts prevented by a mechanism there will no more problem existed.
I think it might worth investing in having an editor look through the document; perhaps for a bounty?
My other main question is about the value of the "instantaneous" transactions. Retailers today are already waiting ~30 days to receive their money in Fiat from Mastercard/Visa. My suspicion would be that 10 minutes is not too long for them.
Do you think that this "instant" value proposition is mostly for the p2p user?
Yeah you're right document is very draft now I'll fix it as soon as possible.
In the perspective of merchants yeah 10 min is not such a time but the problem is buyers need to wait that time (10 min) because if a merchant accept an unconfirmed transaction as a payment and let customer leave, then customers can double-spend their payment transactions by including higher fee to redeem their funds payback. GatePay solves this problem by preventing double spend attacks targeting unconfirmed transactions. Protocol is not making transactions "instantaneous" it makes payments "instantaneous". Transaction still estimates about 10 min but payment accepted instantaneously by payee.
