Gratuitous #Blockchain UC. You can just continuously export the reading to an external DB the driver doesn't own and alert on lower readings

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

That's why the cost of a credit card transaction is several orders of magnitude higher than the backend DB part suggest

I consider that under total system cost. E.g. settling one bitcoin block transaction costs upward of $10 just to cover the used kWh

That can’t possibly be true. Maybe a block has that cost, but definitely not a transaction.
1
Settlement happens in blocks. Whatever gets into that block is determined by how many tx the winner scoops up before trying.

A block will contain about 1,000 transactions and earn the miner 12 Bitcoins, i.e. more than 12k €

For any block they win settling in the hash collision lottery, which isn't very often.

Of course. Yet there are people and companies doing it. They’re not doing it for charity.

yes, but the margins aren't really that great and the trend isn't promising blockchain.info/charts/avg-c…

That’s something we can agree on – scaling is definitely an issue. Something will have to change, don’t know what the best way is
