I guess you've never heard of CQRS then. Blockchains are not on-demand databases, but rather sources of truth from which derived, queryable databases can be constructed.

I fail to see the relevance of your comment.

>Command Query Responsibility Segregation is a software pattern that divides the system into two distinct parts, an append-optimised command side and a read-optimised query side.

My point was about the "append-optimised" part. Of course the blockchain can be arbitrarily fast to query but you can only make about 5 transactions (or "inserts") per second on the bitcoin blockchain on average. Not very impressive as far as DBs are concerned.

CQRS is great. But you can implement it very efficiently using standard logging techniques. Blockchains are just a slow, inefficient implementation of CQRS.
