Just a random terrible incomplete idea in my head. What if instead of the device generating the transaction sequence number, the sequence numbers were provided to the client ahead of time and signed by a trusted third party? Essentially you get a sequence number ahead of time and a window in which to use it.
- dandanua 6y agoIf you know the sequence number ahead of time then you can attach any transaction to it, including two conflicting. The point of hardware counter is that you (your device, actually) sings a counter along with a transaction. You couple them together in a way, that you can't counterfeit, because you can't tamper the device.
