A very nice article about bitcoin and gold virtues if (when?) the dollar collapses:

When the Dollar Collapses, which is better Money, Gold or Bitcoin?
2  Bitcoin / Press / 2015-03-16 "deep web" a mainstream movie about Bitcoin,Silk Road & Ross Ulbricht on: March 16, 2015, 08:34:14 AM
Narrated by Keanu Reeves

Deep Web gives the inside story of one of the the most important and riveting digital crime sagas of the century -- the arrest of Ross William Ulbricht, the convicted 30-year-old entrepreneur accused to be 'Dread Pirate Roberts,' creator and operator of online black market Silk Road. The film explores how the brightest minds and thought leaders behind the Deep Web and Bitcoin are now caught in the crosshairs of the battle for control of a future inextricably linked to technology, with our digital rights hanging in the balance.

In addition to being the only film with exclusive access to the Ulbricht family, Deep Web features the core architects of the Deep Web; anarchistic cryptographers who developed the Deep Web’s tools for the military in the early 1990s; the dissident journalists and whistleblowers who immediately sought refuge in this seemingly secure environment; and the figures behind the rise of Silk Road, which combined the security of the Deep Web with the anonymity of cryptocurrency.

From Reddit:
I was blown away. They interview Andy Greenberg, Amir Taaki, Cody Wilson, and extensively featured the Ulbricht family. They covered the cypherpunks, mentioned austrian economics, Mises, and anarcho-capitalism multiple times. They interviewed the head of Law Enforcement Against Prohibition. They gave a very accurate and largely favorable explanation of Bitcoin.

The focus of the film was basically the history of the Silk Road, the bust, and how unfair the government's trial of Ross was.

They even mentioned OpenBazaar (I almost dropped out of my seat).

Afterwards, they brought the director Alex Winters on stage, along with Lyn Ulbricht, Cody Wilson, Andy Greenberg and a few others. They talked and had a Q&A for ~20 minutes. Obviously, it was extremely positive towards Ulbricht's position and strongly attacked the trial.

This wasn't a Bitcoin conference or a libertarian gathering, this was a major film premiere at SXSW. It was a massive theater (easily more than 500 people) and standing room only, I had to wait in line for a half hour for a ticket.

I still can't believe what I saw. Amazing. Everyone needs to see this film.

Non mi quadra:
Example of double-SHA-256 encoding of string "hello":

2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824 (first round of sha-256)
9595c9df90075148eb06860365df33584b75bff782a510c6cd4883a419833d50 (second round of sha-256)
A me il secondo hash viene:
d7914fe546b684688bb95f4f888a92dfc680603a75f23eb823658031fff766d9 (sembra + corto ma dovrebbe avere 64 caratteri pure lui) comunque e' differente. L0ho calcolato sia con sha256sum da linea di comando che con una estensione per libre (open) office. In entrambi i casi ottengo lo stesso risultato differente da quello della pagina ...

Il secondo passaggio va fatto sui byte del primo risultato, non sulla sua rappresentazione esadecimale, che è quello che fai tu se usi sha256sum.
Come spiegato qui, se usi un tool che produce output binario potrai verificare che il risultato è corretto:

echo -n hello |openssl dgst -sha256 -binary |openssl dgst -sha256

La traduzione italiana di un articolo molto interessante che parla della nascita della Federal Reserve:

Bitcoin segna l'inizio della fine di 100 anni di schiavitù

Lettura consigliatissima.

Grazie tra gli altri ad AlexRossi per l'aiuto nella traduzione.

Siamo veramente delusi dalle accuse di scam che ci sono state rivolte, a dimostrazione della nostra lealtà vorremmo ricordare che stiamo distribuendo una carta Mastercard con la quale riusciremo ad incularvi anche gli ultimi risparmi.

Cointellect è un ottimo esempio per capire come lavora uno schema di Ponzi.

Non solo le dinamiche dell'azienda, ma delle persone stesse che, difendendola in buona fede, permettono che possa aumentare il giro di persone truffate.

cointellect has stopped paying and the team stopped responding to inquiries.

They flew away with all the cash the people gave them, as with any other Ponzi scheme.

Really? Could you please explain how those 100'000 people get more "freedom from oppresive governments" by using bitcoin?  Is "freedom"  just evading taxes, or buying illegal drugs, weapons, child porn -- or is there something else?

Claim: in its 6 years of existence, bitcoin has caused 1000x more damage than benefits to the world.

Bitcoin has given me hope to be one day free from the ideas that governs your way of thinking.

Thanks for continually remind me it with every post you make.

Sidechains irrelevant, Bitcoin UP.

this could very well be true.

in that case, why change anything?
And what if the rally is being fueled by the understanding of sidechains, thanks to the debate of this thread? ;-)
16  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Ethereum: Welcome to the Beginning on: November 12, 2014, 08:09:25 PM
"Counterparty announced that its developers have successfully ported the Ethereum Project’s programming language over to the Counterparty platform, enabling users to save and execute Turing Complete Ethereum code on the Bitcoin blockchain. With this new development, Counterparty makes it possible to execute Ethereum smart contracts on the more secure Bitcoin blockchain."

How will this affect Ethereum? Will the Counterparty-Ethereum platform be slow? Can it be scalable? Anyone have any thoughts?
That simply means that the people that bought ether have thrown away their money.

Now ethereum can work on top of counterparty and tomorrow, if ethereum still exists and useful, will be implemented as a two way pegged bitcoin sidechain.

Them so be it. You, they, whoever can think what they wan,  it dorsnt matter to me anymore . I think SC's are a  bad idea.
You mean this it your position, in spite of every piece of evidence someone can produce?

Breaking the link between the currency and its ledger introduces too much risk to the system.
I completely agree: in fact this is exactly what happened in disasters like the mtgox issue.

SC could help in that regards. There is no guarantee, but there is some hope if it works as claimed: that's what "permissionless transition between the two chains" is all about.
For example, with mtgox we had to wait for its permission before withdrawing the btc on yours (theirs) account. That caused the problem to grow bigger and bigger.

But by all means go ahead. Devs gotta dev and its clear they've lead the way economically for this whole project. Good luck.
We are all on the same boat and it's our responsibility to check their work and warn other users if we see some weak link: we'll try to this job when the first SC will be announced and we'll be able to check the code and its implications.

lol, your stubbornness is gonna help me push this to 1,000,000 views soon enough.

you will single handedly be held responsible for causing the SC concept to fail with all the negative publicity you're gonna create.
What do you know about what are the readers thinking?
You just know the number of views, not their sentiment.

Maybe history will remember you for how much foolish you were being so stubborn in not understanding that 2wp SC can help Bitcoin move forward Smiley
20  Economy / Speculation / Re: Gold collapsing. Bitcoin UP. on: November 06, 2014, 09:44:18 PM
Side chains per se, do not solve all the problems Bitcoin has today, nor are they a guarantee of anything.
What they are is a mechanism.  They may have the potential to solve problems.  That will depend entirely on what people do with them.  They are another tool in the tool belt.  It can be used to build or destroy.  The existence of this mechanism does not guarantee the success of Bitcoin.  It would be nice if it did, and we could all just sit back and wait for the magic to happen.
I completely agree, I'm sorry if I used a worse wording, I think the problem is I'm not a native English speaker and this has effects Smiley

Instead there is a new tool, a new mechanism.  It may be used by all sorts of people, and groups.  This is great, it is the nature of open source collaboration.  However we must recognize that only some people may share common goals with you or me, and others may not.  And you may not know whether any particular SC creator does or doesn't.  There may be wolves in alpaca clothing.
Again, I agree... and "wolves in alpaca clothing" is fantastic Cheesy I'll take this expression as mine henceforth, if you don't mind Smiley

These are the sorts of things that I (and presumably CypherDoc and others) consider with caution.  What makes this even more of a concern is when we see these posts that essentially say "there is nothing to worry about", "this fixes everything" or "the details of the cryptography don't matter".
Those sort of statements are either (a) just misunderstood word choices (and something else was meant by the author), or (b) maybe the author is simply misguided or exuberant , or (c) perhaps they may be malicious attempts to misguide others.
What you wrote here below is sensible.  We may disagree on some matters of preference, but I like that you say what side chains "can" do rather than what they "will" do.  It is important to understand that they can be used and also can be abused.
Again, I completely agree.

The problem is that while I understand they can be abused, I also understand that the problem they can create is one of these two types:

1) an altcoin. Yes, that can be a problem, but it's not a different problem than the one we have right now.

2) a service that fails. Let's remember that a 2wp sidechain is a service completely analogous to the one offered today by a coinbase or a mtgox. We know they can add value to the network, and we know they can fail bringing enormous problems to their users, but they can't harm bitcoin, the network. That's why I consider SC an improvement to the actual situation, and it's because we have an algorithm to programmatically move coins between the chain.
And that movement can be done without requesting permission.
That's not a minor improvement: that's the difference between day and night, and one that can solve a lot of problems, like for example the fractional reserve of mtgox.

I think Cypherdoc is understanding the function and capabilities pretty well.  I also think his caution is reasonable.
I agree that caution is reasonable, and I'm eager to understand the failure cases, but simply I don't find any evidence, not from cypherdoc, in any case.
