How HashGraph apps works?

Question

I try to understand but I still don't get it e.g https://hearo.fm was built on hedera hashgraph platform.

Answer 1

I recommend you read the Hedera Hashgeaph FAQs and the white paper.

If you come up with specific questions, I can TRY to answer them, but it's probably better to ask them directly in their discord channel ( https://hashgraph.com/discord ).
