Hi. I'm the author of the article. Thanks for your interest. I'm glad the piece is sparking a deeper discussion of the technical trade offs of the technology.

I just want to clarify that this article is one of many included in a full Spectrum issue dedicated to blockchain technology, which I had a hand in organizing. From the outset I was adamant that we acknowledge the costs and limitations of blockchains. Part of that treatment can be found in the last half of the overview.

But we also try to hit those notes in a separate piece, which you can find here.

Hi. I'm the author. Thanks for pointing this out. You were not the only one. We've reworked the attributions paragraph to include all of the institutions that had a hand in this particular work. And we also tried to make it clear that the snarks they worked on were specific to the zcash project.


If you have not been charged with a crime, can you just refuse to hand over your cards?


Then they charge you for obstruction (or whatever it's called in oklahoma, in french it's called "entrave à un agent de la paix")


It is obstruction of justice and it's very unpleasant.

If they're so inclined they can take your things by force and you will have no reasonable means of recourse.


Isn't the question, "obstructing what?"


And the answer, of course, is "Justice."

It's like being charged solely with resisting arrest.


Or destruction of government property when you bleed on them during a beating? Ferguson:

That seems questionable, how can they charge you with obstruction when you can just not answer any questions you're not legally obligated to answer.


I tried to write the long answer and it turned out as a wall of text composed of parenthetical caveats. Then I tried to right the short answer and it turned out as a medium length yet confusing answer.

The truth of the matter is that people are barely evolved ape/chimps and do pretty much whatever suites them as long as they don't get their ass kicked for it.


Thanks! I'm saving this comment for its general applicability to, unfortunately, anything.


Yes, that would be the fourth amendment.


I just got a copy of the paper from the researcher. They used 16 study participants. Still not a huge sample size, but big enough for consideration.


I went to the website for the General Prosecutor's Office of the Russian Federation and nowhere can I find the document that is circulating in all these news posts.

This link, which you maybe shouldn't click, because who knows what's going on here, [http://www.genproc.gov.ru/smi/news/genproc/news-86432/] indicates that it should be in the news section. But when I go there directly, I can't find it.

Has anyone been able to even verify the authenticity of the original announcement, let alone interpret what it means? If so, can you share where on the official website you found it?

Thanks.


Wouldn't a better way to make a point be to simply stop buying Apple products?


They know that no one really cares about Bitcoin enough to materially affect them via a boycott, so it's easier to write a blog post about it.


Well, I'm guessing the people who care about this iOS app already have Apple products.


You have to keep in mind that during the course of those six months, Silk Road was taken offline. SR was assumed to be driving most of the non-exchange transaction volume. The fact that its dissolution had no impact on this metric is quite surprising and I'd argue it's an indication that "legitimate" trade activity has actually increased over the last few months.

Trade volume has skyrocketed. IE: people are trading more BTC for USD than ever. It wasn't since the Crash of April since we've seen trade volume this high.


Normally I would agree with both of these because they seem to be the reasons other companies introduce currency schemes. But in this case I think it's telling that Amazon first made the announcement on a blog for app developers. My guess is they are trying to attract developers by guaranteeing them a market.

If you're interested, I wrote about it in IEEE Spectrum when they first announced Amazon Coins in February.

I've corrected it. Thanks.


This guy came up with a similar idea 2 years ago.

This guy won reddot design award in 2007. So this is much more older than 2 years
