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".
We are working hard on the demo app, in its current form it does not have full blockchain integration it is just to demo how the GAT Wallet, interfaces with the GAT Market Place and Exchange and demonstrate the mechanics of buying and trading in the GAT System.
That's great! We don't need full features to have a sneak peek on the platform, but development based on early iterations has proved to be successful.
