Using tendermint as blockchain architecture is not new to me . In fact I have seen Cosmos is about to use it as their primary blockchain structure. Lets see how effective each would implement it.
Cosmos is founded by the Tendermint people. Let's say we are the first third party to use it as a primary chain.
We also have very different goals and long-term visions. But I definitely see us working with Cosmos in the future, I love their idea of a distributed network of different chains.
