Interesting things in crypto-blockchain tech, today:
* Origin
* NuCypher (disclaimer: I'm on this team)
* Loki
* New version of web3.py / other python tooling becoming mature
* Trustless Quorums
* Distributed validation
I can go on and on. But I just don't see how anybody can think that these are uninteresting times for this tech.

Really? For me it's the almost-a-decade of hype but seeing very little in practical utility beyond speculation, ransomware, and some light crime. As an example a New York Times writer just tried to spend the weekend living on Bitcoin and failed egregiously: https://www.nytimes.com/2018/04/16/nyregion/new-york-today-l...
I'm happy to admit that there's more activity in the space than I could possibly keep track of, so there could definitely be a pony in there somewhere. [1] But it shouldn't be any surprise that after so much hype resulting in no apparent useful effect on the rest of the world many people are skeptical that the cryptocurrency world will ever produce anything more than dubious claims, Ponzi schemes, and million-dollar thefts.

Our system allows an actor (Alice) to select any number of recipients (Bob) in a Policy. Alice can disappear from the network forever, and subsequently, any DataSource can encrypt data, using Alice's public key, which can then be decrypted by all of the Bobs.
That's pretty cool to me. I do think that medical devices / IoT are an obvious use case. I also hope that our tech is used to build selected consortiums of journalists, whom whistle-blowers can then encrypt for only by knowing the policy key.
Another interesting use case is for distributed ops: if you have a number of streams of operational data that you want to share only with a certain number of watchers, presently you need to trust a centralized service to do that.
I'll admit: I'm not really the use case guy. But I am waist-deep in the python over here, and I can tell you we have a good thing going.
For years and years I've said, "Yes, that is a pretty cool technology, but what real-world value is it currently providing?" One common answer is, "But it's a really cool technology!" No argument, but that seems to miss the point. Another is, "I'm sure it will be amazing!" Which again, misses the point. A third is, "It might be great for X," but without any real proof that people doing X want the technology, without demonstration that the current alternatives are inadequate, and without apparent recognition that a future hypothetical does not in any way satisfy somebody looking for traction.
Plenty of technologists think they have a good thing going. Right up until the investor money runs out and customers have failed to show up.
As an example, look at 3D movies and TV. 3D has been about to change the way we see things since the 1950s. There is no denying the technology is very neat to technologists. Early adopters even get excited! And then it turns out once again that customers don't really care. This pattern goes at least as far back as the Brewster stereoscope in the 1850s.
So please, don't be shocked that people are tired of blockchain/cryptocurrency hype. That you find the technology interesting does not mean that anybody else will find the (lack of) actual deployed use interesting.
If the review I read is correct, that's an ordinary debit card that one refills by selling bitcoin. Which has approximately no value to most people, because they already have debit cards that work just fine.
It could be that bitcoin will eventually end up being useful as a currency, but its high volatility means that day hasn't come yet, and won't come soon. Prominent bitcoin advocates are happy to give up on it as a currency altogether. E.g.: http://avc.com/2017/08/store-of-value-vs-payment-system/
Of course, the fact that other technologies have gone through both a peak and trough before settling between them isn't confirmation that any particular technology will. (I bet Theranos won't rebound.) It should cause one to discount the sheer volume of disillusionment, where not accompanied by evidence, just as one should previously have discounted the volume of hype.
Buzz buzz.
The reason this critique is so prevalent on HN is because a lot of us just watched the last 10 years of the internet go from "that thing that is going to democratize technology and knowledge" to "a centralized management system for privacy invasion." The reason for this seems to be, loosely stated: "no one wants to run their own mail server." Because no one wants to put the effort in to dealing with running an email service, we allow Google, Facebook etc. to run them for us. The reason for this is because our economy is based on specialization of labor: it's by design. I can choose to spend my time running a server, but allowing someone to do it for me is orders of magnitude cheaper due to economies of scale, so unless I have a really strong demand it's probably not going to happen.
The blockchain allows for us the same effect as "running our own email servers," and most of us really don't think it's likely that people are going to want to host their own nodes in the blockchain, because, referring back to Conway's law, there are fundamental political aspects to our culture that do not support this architecture.
The way I see it, one of the big assumptions of the technologies in this space is that participants are only acting out of self-interest. Meaning, that there's a strong push towards designing systems where behaviours that are beneficial to the network are also economically rewarding.
Meaning that in theory, cryptoeconomics could be seen as an attempt at finding a solution to the problem you mention.
There are so many projects that promised the world and did not deliver, as well as so many projects that ended up being outright scams, that it's not surprising that when someone says "but what about Blockchain X, Blockchain Y and Blockchain Z projects?", we all roll our eyes and think "I'll believe it when I see it."
It's not as if any blockchain project has provided a long lasting use case beyond speculation, in which case you calling us all idiots would be warranted. After 10 years of flops, the burden to show how interesting these technologies are is on you now.
I don't understand this assessment either. How do you square this with, for example, people who have been able to obtain psychoactive compounds and other medicines that were previously unavailable to them?
1) The whitepaper describes the nature of our network and how Alice and Bob use it. It does not describe (and isn't meant to describe) node operation except as Alice and Bob need to understand it. We'll have an additional node operation whitepaper that describes the smart contracts in more detail. We - and I know this may sound strange - decided to build our cryptography and network first and foremost rather than race to build "something, anything, as long as it's blockchain."
2) Do you think that the whitepaper insufficiently describes how Alice and Bob use the blockchain? If so, do you have suggestions for how we can do this better? I think our whitepaper is pretty solid, FWIW. If you are Alice or Bob, I think this gives you exactly the understanding of the blockchain application that you need.
Our website is not designed to appeal to VCs per se; we are not raising money right now and, frankly, if we were, we don't need a website to do it. Our team and our repos speak for themselves, IMO.
As I explained in our other comment, our whitepaper mentions the blockchain integration in all the places that matter. I'm surprised to hear that 5 is not enough.
That's actually not quite right. I'm one of the engineers here, but allow me to put my evangelism hat on a bit here. We're building a decentralized key management system similar to AWS KMS or Google Cloud KMS -- except decentralized.
We use proxy re-encryption to do this. You can read about how it works in our Umbral blog post[0].
Several large applications are within the healthcare world. This allows patients to be in control of their own medical data and to share/revoke their data at will with other doctors, hospitals, etc. This lets them retain their own encryption keys without trusting another party.
Its market/end user is specifically anyone who has a need for a KMS. I Would also like to point out that NuCypher can be used as a consumer grade KMS -- something that I am exceptionally excited about.
