I can see how it might work, though. I know you can track the provenance of a single asset (resource) via blockchains. You can read about that [here, about tracking diamonds](http://www.everledger.io/). That was the first credible use of blockchains that I ever saw, except for currency speculation and criminal activity.

But Provenance promises to track processes with their inputs and outputs, as well as the history of a given resource. They want to attract large corporations. They want to track every economic event with barcode readers, RFID thingies, etc. They want each economic event to be digitally signed. So some agent (presumably a business) will digitally sign the log of a process and its inputs and outputs. And all of that will exist in the Ethereum blockchain.

I think that is all interesting. Even ingenious. Might even work, within some boundaries.
