I would not have thought of that. Using Blockchain to prevent rolling back the odometer in used cars (ie. 'clocking' or 'busting miles'.

You do get that not trusting and paying someone to operate that DB is the whole point, right?

I understand that being the assumption. I'm entirely unconvinced that it works out economically.

with POW, the total system cost of a blockchain tx are astronomically higher than putting a record into 2+ DBs

Additionally, sometimes even setting up the business relationship with the intermediary is either impossible or way too costly

Here, the focus is one car and you want proof of monotonically increasing readings from that car. It's not even the right structure

How so? If over a 10 year car history, I get 20 entries that increase monotonically, that鈥檚 sufficient?
