I'm so glad the sentiment has changed on this useless garbage. Why would anyone want to decentralize car security? Porsche could just unlock your car through a centralized app. Why does everyone need access to that?

A remote car key. You've invented a remote car key.

#13So I read this and I can't tell what it actually does in the car.
I also read through the thing, and it was all empty buzzwords and white noise to me.
Was hoping to at last have someone describe an actual use case for the blockchain, but nope, another blank.
Re: Porsche introduces blockchain to cars
#14Porsche has been playing with new ownership models recently, including a sort of membership club where a fixed monthly payment gets you access to any model. So this blockchain-based entitlements thingumy could be seen as an attempt to put in a flexible technology to support more experimentation along those lines.
What they are doing is just the next logical step from personal leases - and it's actually brilliant at that. Instead of say, a lease at $1000/month for a new Porsche, you pay $2000-3000/month for access to almost any model whenever you want it - but I imagine it makes Porsche a lot more money as long as most of the fleet is occupied at any given time.

Sounds like you/porsche can allow lock/unlock access via blockchain, using smart contracts. Does this open the door (no pun intended) for governments to deliver subpoenas for getting access to locked cars? Convenience is always at the expense of freedom.
Do you think this could be used by rental agencies and car sharing services without having to be managed by Porsche? What about privacy; would it be possible to identify the current occupant of a particular car from inspecting a public ledger?

Well as we have seen, there are never bugs in smart contracts. Cannot wait until a hard fork is required to prevent thieves from opening my car.

Your Porsche disappears before your eyes.

It's even worse than that. They've invented a remote car key where, if 51% of the other key holders agree, stops working.
This stupidity and fetishistic lust after overcomplication and fad chasing must end. I can only hope the mechanical engineers are more sensible.

Exactly. That's the kind of thing (and extensions of) that you could conceivably use a blockchain to support, if you think about decentralizing the fleet.

Can’t wait until it costs $30 and takes 45 minutes to unlock my car!

Sorry, but you got it wrong, the real money is in the locking tariff ... ;)
Re: Porsche introduces blockchain to cars
#20Just in case, the previous mechanism wasn't that much safe:

The paper has been published only in 2016, with a few amendments to "hide" (maybe) the parts that could have led to replication by thiefs:

Please note how the Authors only tested a few VW models, but Porsche and a number of other luxury car manufacturers used the same chip/mechanism so that itis very likely to be hackable in a similar way.
