Hi there, We've been using Tendermint over the past 3 months for our company's project and the experience has been very smooth so far. As a developer, I believe that tendermint embodies a very powerful way to start coding your blockchain in a very simple manner. The ABCI protocol is quite straigh forward and depending wether you want to create your own private blockchain or a sophisticated public one, it is already quite robust at this point. The range of things that you can do is pretty wide, you can digitalize your assets or setup a proof of existence blockchain for your documents. Definitely the best framework out there, I believe.
