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.
- simias 9y agoI 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.
- darawk 9y agoCQRS is great. But you can implement it very efficiently using standard logging techniques. Blockchains are just a slow, inefficient implementation of CQRS.
