“Before we proclaim these solutions are blockchain killers, guess what DynamoDB uses for replica synchronization to figure out the correct version of an object? Merkle trees! Exactly what we see in blockchains!”

But Merkle trees are not Blockchains (they are what GitHub and the like also use for synchronisation) and surely it could be argued that this database which uses them IS potentially a blochain killer if it is easier to develop on / cheaper and easier to run?

Why have the likes of Google and Microsoft not pursued a blockchain based approach to their probelem space?
