That's great to hear as it's been a long time coming. Congrats to the team!
I wanted to mention another current use case of the Halo Blockchain due to its instant/free transactions is voting in the blockchain.

"Following on from this partnership agreement, Horizon State is now using Halo to run the vote in New Zealands The Opportunities Party (TOP) leadership race. Halos unique architecture and fee model make it the right chain for collecting votes from a large population or in a situation where we must run several consecutive votes; The benefit of using Halos solutions today becomes quite apparent in the lead-up to running multiple campaigns in the next few months."
The fact that they have instant and free transactions is going to go a long way with real world use cases as we are already seeing.
