That's an ignorant claim. Proof Of Work is only one of available algorithms to mine transactions. Algorithms like Proof Of Stake and Proof of Authority consume virtually no processing power.

Again, very narrow view of blockchain. Because Bitcoin requires a lot of energy it doesn't mean every other blockchain implementation does.

It depends. It can be a flaw or an advantage, depending on the end goal of a specific blockchain implementation

Yes, blockchain can and already is used on many real world scenarios. Bitcoin is really a very bad example of the potential of blockchain.
There are many types of blockchain implementations, with many types of consensus algorithms beyond Proof Of Work (which, in bitcoin, is a specialized type of Proof of Work). Some of the top alternative consensus algorithms:
- Proof Of Stake
- Proof Of Authority
- Proof Of Elapsed Time
The most power hungry is obviously Proof of Work, which is specially hungry for bitcoin. Other implementations requires much less power. The other ones require virtually no power (except for a few processing cycles) which make them very practical cost-wise.

It's not likely that industrial machinery needs it in any conceivable way, especially the ones which perform multidimensional analysis in real time to provide automatised quality control.

I'm pretty sure multidimensional real-time analysis for quality control is techno-heresy.
Have you ever tried debugging a system like that, when sh*t goes wrong? The costs involved are insane.
Considering the fact that it should reduce costs, it's a fundamentally flawed concept, in my humble opinion.

20 years and running of market which is expanding, the costs involved are fairly reasonable and the safety of the customers rocketed sky-high to the point that now it is mandatory to use these machines even in the US, which is the last big nation to have imposed them to food producers (FDA regulations are hard to pass but fortunately not the hardest, that medal goes to French ones, they required only small hardware adjustments).
As for the saving, it's only an expense... but it's better to spend some millions now rather than losing billions because customers don't trust our customers' products anymore (who would feed his/her infant son with foods that may contain undetected glass shards or metal shears? And that goes for other products as well).

Huh. That actually makes a lot of sense.
Re-reading my previous reply, I honestly don't know what I was thinking there.
Apologies for being an ass and thank you for being so reasonable.
I'll make sure to drink my coffee before going online in the future.

No apologies are needed  I admit my field of work is small enough to be virtually unknown, which is half a damnation since I'm out of the mainstream technologies and required knowledge and half a blessing since I can cover jobs most of the new developers aren't prepared to (who ever needs to shave off milliseconds from a function rewriting its core with handcrafted assembler?).
Don't worry about your answer since it is true: it's expensive, and viewed as only an expense, and wouldn't work in fields different from mass food (and pharmaceutical) production, where inspecting each and every product that goes out of the production line is of paramount importance... and it has to be done fast enough (up to 30 products/second) to maintain effective production volumes.

I've only seen it employed once, and that was in an industrious setting [vague on purpose here].
The idea was to intentionally create tons and tons of complex operational data, which could then be data-mined by an external company.
The aim was to figure which jobs could be combined or culled all together, in order to save costs.
The entire idea was so mind-boggling stupid, it left a sour taste.

Blockchain is some security mechanismus which is providing also privacy."E-cash" is a good thing, but I think Bitcoin is some shady hype.
If it is for real the USA will publish its own "Bit-Dollar" and rule all currencies.
I like hard gold coins a lot more, but Visa and Mastercard are real companies to invest in the e-cash business
