Give the smart meter a private key protected in hardware, give the chain its public key, and you can now verify things.
- thomastjeffery 6y ago> protected in hardware That's the fallacy of DRM. There's no real way to keep data from a user.
- cloudhead 6y agoSo given a locked iPhone, you are able to extract its private key?
- dfgdghdf 6y agoExactly. Why do software engineers (myself included) so often confuse what is possible with what is practical?
- craftinator 6y agoWe do that because our job in general is to ignore current practical limitations. The line between practical and impractical changes based on what we make; the job is all about creating solutions that either make a goal more practical, or improving the efficiency of a standing process. This isn't just a problem with software engineers, but most engineering disciplines. It's impractical to transport logs hundreds of miles for processing, until we create a system that can do it efficiently. It's impractical to keep detailed records of billions of transactions, until we set up a database and reporting infrastructure that can handle that load.
- hannasanarion 6y agoNo, but you are able to hook another device up to the battery so that the iPhone is wrong about its own power usage and phones home with incorrect values.
- lordlimecat 6y agoiPhones are a 15 year effort by a trillion-dollar market cap company to produce secure hardware that retails for $1000, and still regularly gets hit with root exploits. This is your model for securing electric meters?
- helsinkiandrew 6y agoSplit your incoming power to two lines and put the smart meter on one of them and it will register half the power. Route power from your diesel generator through the meter that's meant to be recording your solar generated power. No amount of private keys and digital block chain security is going to provide physical security
- cloudhead 6y agoCan’t you do that today though? ie. Circumvent your meter? It’s illegal though.
- robjan 6y agoIf the only way to cheat is illegal and can be done on the Blockchain anyway then why use a Blockchain rather than a database?
- coldpie 6y agoApparently was enough to dupe Woz and get this to the front page of HN. Another blockchain success story.
- helsinkiandrew 6y agoResidential its harder but an industrial/commercial property could possibly have multiple power inlines, a diesel generator for emergency power, and perhaps solar panels on the roof and batteries. It may have agreement to use power within specific ranges during the day for different prices and supply power back to a power company or neighbouring businesses. Under those conditions it's always possible to divert power to 'adjust' the perceived power usage. My point was that block chain doesn't validate anything - a private key will prove that the data (good or bad) is from the specific user, block chain won't validate that its good.
- Apylon777 6y agoIn most jurisdictions in the USA renewable energy generators are registered and audited by a third party, (like mrets.org where I work). Anomalies with generation data can be compared directly with data from the grid operators. Utilities will also require these commercial operations to have a "commercial energy meter" which are very expensive.
