Good project, very informative whitepaper. Reading it I realized that IOTA hadn't had a consensus algorithm at all - just a DAG database with centralized server called the coordinator which decided in case of double spend and they were hoping find a solution - LOL! The good thing is that they recently invented new consensus algorithm which should implement very soon.
Talking for IOTA , I would like to highlight that this (in Tixl's whitepaper) is not the true though
Last but not least, Tixl makes usage of quantum secure cryptography, which is not used by any other
competitor.
as I know IOTA's transactions are quantum resistant so may be you should mention it in the white paper in the sake of objectiveness. IOTA's transactions are not private though so it is not direct competitor of Tixl.
I want to give you an idea because really like your project and will invest in it. Will be possible to use DHT to store your DAG structured database in order to reduce storage requirement for nodes and to remove the need for huge historical nodes?
Another idea is to change this name - tixl does not sound as currency. Brainstorm it and choose anotherone because later will be harder (for example raiblocks->nano). This is subjectivly anyway, may be only I don't like it, make a poll.
One question, what this means in more details please
Last but not least, Tixl can only succeed if as many people as possible use TXL for their payments.
Best regards.
