I came to ask the same thing, I don't understand what part of the core offering (voice assistant) requires the block chain. I can see how you might be able to shoehorn it in there, but it doesn't seem very practical or useful for customers. There's also very little about its use on the website.
Hi bluehatbrit. We will publish our whitepaper in a few weeks, which will thoroughly detail the usecases for our blockchain, and how it fits in our roadmap of building 100% private voice assistants.
