> I know. I think if I read "scalable" and "blockchain" in the same sentence again I'll scream. I acknowledge the hype out there.
FYI we were working on blockchain in 2013; long before the hype. We started encountering massive scale problems in 2014 and working on it in 2015, long before the "scale + blockchain" hype. We started work on this. So we're not doing this because it's some fancy combo of buzzwords, we're doing it because we identified a problem years ago, and have been making steady progress to improve it ever since. It was a surprise to me to see BigchainDB to hit HN front page today, since we've been shipping it since Feb 2016!

Re CockroachDB: it's a cool technology. The big difference is that it's distributed but not decentralized. That is, the compute resources (in this case mainly storage) are spread across many machines; but the control is in the hands of a single entity / sysadmin. Whereas decentralized means the the control is spread across many sysadmins; and even a few rogue sysadmins won't take down the system.
