Not quite - see other comments about needing a trusted local source the first time you sync up. Otherwise, forks are never tolerated. If the keys leak, and there's a new history, i…

You're probably right, we could have. The primary reason to use our own is to support Merkle proofs of the state. For the Jepsen tests, it wasn't really needed, and may have been s…

It means we simply give two different nodes the same signing key and get them to sign conflicting proposals and votes. A more complicated Byzantine fault would take into considerat…

It's not some single centralized trusted source. It's a local trusted source. Like a friend or a shop or a website you make payments on that uses the network and has been keeping u…

That's right. The first time you sync up, you're particularly vulnerable. You need to authenticate first against a trusted source.

I think it's still a big experiment and there's a lot to figure out around the right state machines and the right models for computation in these systems. We hope that Cosmos and T…

Thanks! 1) We're looking to get the Cosmos Hub up before the year is out, and to roll out production support in 2018. 2) Great, if you like. But if you want to support light client…

Good points. Tendermint aims to be a general purpose consensus system - how the validators are actually chosen and changed is outside Tendermint's domain. All Tendermint wants to k…

Tendermint consensus is more like classic BFT consensus than Nakamoto. It provides deterministic finality/safety with every block, unlike the probabilistic 6-block safety of Nakamo…

Have you considered using Tendermint? We just published the results of a few months of Jepsen testing: https://news.ycombinator.com/item?id=15175984

Thanks! A year ago we were just two guys working on this project on the side without any funding. Now we're a full time team of talented devs swinging in full force. The comments a…

Tendermint doesn't use Proof of Work (PoW). PoW is hard to test with Jepsen because it only supports probabilistic safety, which means the chain can constantly reorganize. If I'm n…

It means "arbitrary". Byzantine faults refer to "any arbitrary behaviour by the machine". The term was coined by Leslie Lamport in the early 80s when he defined the Byzantine Gener…

Thanks for the compliments! We do really care about quality software design and testing, and we're looking to hire folks that share our values: https://tendermint.com/careers Lots …
