I first tried to use Tendermint a year ago and honestly it was rough. Their codebase had very few comments, including things a go linter would harass you endlessly for like function comments, and the docs were barely existent. The codebase was also not exactly what you would call "idiomatic" go.
I checked back in at the Cosmos fundraiser, and then again a few weeks ago and their documentation while still needing work, as well as their code quality is definitely improved. I like their idea and I want the project to succeed, and things like independent third party audits are the way that happens.
Kudos to the team for not being afraid to look for the warts, better to get them now then later.
