Blockchain is not a database. It's a document timestamping service (document being a short program that describes where goes what part of a coin, in the case of Bitcoin), it's just a service that doesn't use a central place or a trusted third party to produce (or keep) timestamps.

If you were to use it as a database, then no wonder it would suck horribly. It wasn't designed for that.
