Sounds a little like the NoSQL trend where everybody jumped on it only to find out that NoSQL is only applicable for a few use cases.
what?!?!? I hope that's sarcasm.

I can’t tell if you are being sarcastic or not, so I assume this is a serious comment. Can you share some examples of use cases where DLT is going to be transformative?
I mean a good example of the need for DLT is the fact that no one in the country can buy romaine lettuce right now. Does it really make any sense whatsoever that no one in the country can eat lettuce for the next couple months just because one farm got contaminated with E. coli?
Could you talk me through how a blockchain solution would help avoid this in a bit more detail?
I've seen lots of vague "blockchain for supply chains is a great idea" pronouncements but I don't get how it would actually work.

Can you let me know how these "private" blockchains utilize proof of X to determine consensus? E.g. proof of work, or proof of stake, or something else? The thing I never understood with private blockchain tech is that the "traditional" blockchain (i.e. Bitcoin) relies on proof of work, and the only way this is viable is to have tons of resources working on these proofs so that you don't get a 51% attack (there have…
A useful term here is "Nakamoto consensus," which I think refers to the proof of X thing you're talking about -- consensus schemes that are resistant to sybil attacks among anonymous validators. And I think you're right -- adding Nakamoto consensus to private blockchains makes no sense, because by definition they don't have arbitrary validators. And without Nakamoto consensus, "blockchain" is just rebranding of old a…
> rebranding of old and boring tech
A distributed merkle-chain database is still pretty innovative. A good example is git. I think what many private groups want is a "binary git for transaction data". Everybody can review their own copy of the shared chain with signing of new links in the chain.
Now that isn't really a full blockchain, but is a different kind of thing from a central RDMS.

Not really. A few years ago there was a lot of hype around NoSQL and everybody wanted to jump on it only to find out that in many cases NoSQL didn't make anything better.

I'm sorry but this does not always apply in the real world. Someone getting everyone onto a blockchain is a one-time project, perhaps with an annual maintenance fee. Running an industry organization is an order of magnitude (or two) more expensive. Trusting someone to build an (open source) application is not the same as trusting them to centrally host it.
How about a thing that's almost-but-not-quite a blockchain? E.g. a decentralized multi-master Event Sourcing datastore. No proof-of-work, no mining, no ledger. Anyone who can connect to the network (i.e. is whitelisted) can append whatever they like, and it'll get replicated to everybody. But nobody can delete/overwrite (without losing consensus); and every event is signed by its emitter. It's just an append-only log…
so ... sort of like git?

But what about the Emerging CD-ROM Industry? (I want to know more about Bill Gate's goat!) https://www.questia.com/magazine/1G1-6501528/microsoft-s-thi... The 1988 Microsoft CD-ROM Conference held in Seattle in March, attracted about 2,000 industry insiders. The tone and ambience of the conference reflect a definite change in the industry.

That actually was a thriving industry for a few years in the 90s.
Yeah CD ROMs were fantastic technology. I had a full encyclopedia on my personal computer! And so many great games!
They filled the gap very nicely until broadband spread widely enough to allow the web to destroy any need for them.

> I still have a lot of faith in what Blockchain will eventually be able to achieve. What does this even mean? Its a really beautiful solution its just lacking a good problem.
https://hackernoon.com/how-blockchain-technology-could-fix-t...
The solution offered is:
"But instead of giving full maintenance or full publishing rights to new collaborators, the original developer would give new maintainers or a CI system only signing rights. So they would sign their releases and after a careful review the original author would countersign stating that he checked and approves these changes."
This is 100% equivalent to the maintainer merging a pull request. The other half of the solution is "we need to pay open source maintainers," which doesn't need a blockchain either.
Blockchain doesn't help this scenario at all.
Re: Blockchain study finds zero success rate and vendors don't call back
#78I said this in another thread but I'll say it again here. I am downright shocked at just how much of a failure this technology has turned out to be. How can this many brilliant people work on an area for this long and produce almost nothing of value? I suppose it happens in areas of "pathological science" like infinite energy machines, but those are areas where the tech doesn't work and probably violates laws of phys…
FYI: the "Star Wars" laser missile defense system was not entirely a failure.
There were 2 parts to SDI:
1) space-based rocket-based ABM, which worked well. You can watch the SDI video:

2) laser missile interception, which did not work at the time.
However, with recent improvements in fiber optic transmission efficiency, this works on ships today.
The Russians have an ABM ring around Moscow based on ABM rockets.
Both Reagan and the Russian leadership did not accept the MAD doctrine, hence the above defense programs.

#79Blockchains make no sense when the "asset" they are tracking have to be imported from the outside world because they lose the trustless property which is the whole point. For example supply line tracking blockchains. "Look this piece of beef was at place X on time Y with temperature Z, I have a hash and everything". Yes but how do I know that you didn't swap the barcodes or you didn't fiddle with the GPS or the therm…
I always say "the moment you need to verify that a human did something outside the system, your blockchain is broken."

#80I'm really not surprised. The most interesting thing about your business shouldn't be your choice in data-store.

CD-ROM and "multimedia" was useful in the era before internet speeds caught up with the capability of computers to show video and sound. My "Time Almanac 1990s" CD-ROM was useful, and would probably be on par with what's available online now, in quality and production values.
