BigchainDB is not production-ready. You can use it to build a prototype or proof-of-concept (POC); many people are already doing that.

BigchainDB Server is currently in version 0.X. (The Releases page on GitHub has the exact version number.) Once BigchainDB Server is production-ready, we’ll issue an announcement.

The BigchainDB Roadmap will give you a sense of the things we intend to do with BigchainDB in the near term and the long term.
