They could still make a demo interface and an imitation of an internal high-speed blockchain.
An imitation is not that hard, you just replace the blockchain with a regular linked list database. But then it is not a blockchain anymore and that defeats the purpose of the demo.
But it's just to show how the final product should be like, so the full integration of blockchain is not needed for the demo, or am I wrong? I would be satisfied with seeing the product, it doesn't have to be "perfect".
What I meant was if you remove the difficult, time consuming tech that makes GATCOIN GATCOIN, you almost end up with any other loyalty program.
But the point is moot since they are already working on a demo.
