The objectification of women in Asia must stop.  Consider the plight of Rina Bovrisse in Japan.  Even the high commission for human rights and women's equality in the United Nations Forum for the Development of Human Dignity for the Twenty-first Century has spoken out in favor of valuing women for their brains, not their looks.  According to UN high ambassador Kofi Butros Butros Aly, "women will play an increasingly productive role in the knowledge industries of the 21st century"

JUST KIDDING.  Carry on...

I'm new to this thread.  Without reading all 989 pages of posts, can somebody summarize the prevailing Zeitgeist of this thread?

Shouldn't it read, "Bitcoin collapsing, Gold is steady"?

It reminds me, as a gold bug, of the 'collapse' in gold the last few years.  Since my average price is well below $1000 an ounce, I don't really care if it falls from its all time high, as I'm still above water.

Is it the same with most of you BTC holders?  Or did you buy at the peak?

3  Bitcoin / Armory / Re: Armory, Bitcoin Core take a long long time to install: 48 hours + (BTC = null;) on: January 04, 2015, 02:54:12 PM
Update:  weeks after I uninstalled Armory, I found out my hard drive was failing.  Not sure if it was related to the problem I had with Armory taking several days to install.  In fact, you could argue that the installation of Armory put my hard drive onto its last legs.  Luckily, I had SMART turned on in the BIOS and it told me the HDD was failing, and shortly thereafter I was able to clone my HDD onto a new one with no data loss or need to do a reinstall.  So everything is cool now...but I am not going back to Armory, sorry!

At 8" round and 2" thick Mazuma weighs in at just over 12 pounds and is carved from the highest grade Purpleheart wood a person can ever get their hands on. This high grade Purpleheart only comes from the top 3 or 4 feet of trees that exceed 160 foot tall and contains the highest resin concentration of Purpleheart wood which leads it to turning the deepest "crown royal" purple color you will ever find.

Please feel free to ask any questions below, and if your board and just browsing the web, take a minute to check out my other Bitcoin artworks.
Awesome.  This is a truism come to life: "making money is an art"!

I do have questions about how you managed to get this wood imported to the USA, which has very strict import laws (even Fender guitar has problems with getting rare woods imported).

Maybe you have connections, or found some local source, or don't care to say, that's fine.

Some economists have opined on BTC

Translation of the below paper:  good news and bad news about Bitcoin. 

Good news:  Bitcoin is here to stay, as you will always be able to use it in the black market. 

Bad news: governments will regulate it so it remains in the black market.

The Political Economy of Bitcoin
November 28, 2014
Abstract
The recent proliferation of bitcoin has been a boon for users but might pose problems for govern-
ments. Indeed, some governments have already taken steps to ban or discourage the use of bitcoin.
In a model with endogenous matching and random consumption preferences, we find multiple mon-
etary equilibria including one in which bitcoin coexists with regular currency. We then identify the
conditions under which government transactions policy might deter the use of bitcoin. We show that
such a policy becomes more difficult if some users strictly prefer bitcoin because they can avoid other
users holding currency in the matching process.
8  Alternate cryptocurrencies / Service Announcements (Altcoins) / Re: Augur - a decentralized prediction market platform on: November 18, 2014, 04:57:53 AM
I read the paper quickly.  What Augur seems to be is:

1.  A prediction market, using bitcoin as the medium of exchange, but also allowing you to use other currencies, including it seems, Truthcoin, and, for stability (ironically!?) the US dollar

2.  using Augur one can avoid the numerous anti-gambling laws that apply to prediction markets (sad but true, as I am a fan of prediction markets; iPredict in New Zealand is one such example)

3.  using Augur you can buy or sell shares in a prediction, and it is locked in the Augur blockchain.  If your prediction comes true, then somehow (not 100% clear how) you can collect on your bet, if: (i) a super-user, or users, with high "reputation", reports that the event occurred as predicted, and, (ii) once this super-user(s) (with typically many such super-users reaching a consensus) says a prediction has occurred, then the Augur blockchain is 'unlocked' and people who made bets one way or the other can collect, via the blockchain, on their bet (if they won), or, if they lost, their bitcoins/truthcoins / USD amounts are also transferred to the winners.

4.  From the OP " If such an individual is dishonest, they are punished, and if they tell the truth, their reputation increases (this is discovered via principal component analysis)." - what is the punishment?  A hit in their Reputation points?  I suppose so.

Can any reader confirm the above?

Best of luck.  My only small complaint is that the Augur website, powered by simple machines forum, looks exactly like the Bitcoin Forum, which is somewhat confusing.  Best if you change the design layout a bit so not to give the impression it is part and parcel with this forum.

Huge raid to shut down 400-plus dark net sites

The BBC understands that the raid represented both a technological breakthrough - with police using new techniques to track down the physical location of dark net servers - as well as seeing an unprecedented level of international co-operation among law enforcement agencies.

Prof Alan Woodward a security consultant from the University of Surrey who also advises Europol, said that the shutdown represents a new era in the fight against cybercrime.

"Tor has long been considered beyond the reach of law enforcement. This action proves that it is neither invisible nor untouchable," he said.

Bitcoin has died about 30 times...if the media had the ability to kill it, it would have died a long time ago.

Right. So long as there is usage for it, it will never die.

At worst, the price will drop a lot. But that will only hurt speculator and miner and not end consumer.

What makes you think there will always be a usage for it? The price drop hurts people who want to actually use it as a currency, because otherwise it's just a token.

I tend to agree.  Not only is Bitcoin dying, because of price decay, but also most people (mainstream people) don't care too much about anonymity, and are turning to their smart phones to do digital transactions.  You don't need a crypto-coin, just MasterCard/Visa.  See more here: http://www.juniperresearch.com/viewpressrelease.php?pr=382

A company called Monitise is already partnering with Visa/Mastercard/IBM.  http://www.valuewalk.com/2014/11/monitise-future-mobile-money/    (Note this telling quote: "Implicitly, Monitise has acknowledged the key ingredient to banking is trust between the institution and its customer. Just as a no-named ATM draws suspicion, so too does an unbranded mobile application. By providing a customizable open interface platform to banks, Monitise can leverage its technology through the customer’s trust for their financial institution. ")

I do hope Bitcoin's price recovers however...
14  Other / Politics & Society / Re: Anyone following the ebola outbreak? on: November 02, 2014, 06:19:52 PM


Even if ebola does not cause sneezing.  People with ebola can also get a cold or flu.

That's a good point.  Can you imagine the microdroplets being sprayed from an Ebola-sufferer who has the flu?  Worse, since Ebola has "flu like symptoms", they will be masked by somebody who has the actual flu, and this person will be spraying everybody in the office with their body fluids, and nobody will give much concern, thinking it's the 'ordinary flu'.

Now imagine a person who has the flu, Ebola, and HIV, coughing, sneezing, and engaging in risky behavior.  A trifecta!!!  Quarantine anybody?
This is why, if ebola is not taken care of by flu season, that it will become a much worse problem in the US.

It is not realistic to be able to quarantine everyone with the flu, as our healthcare system would not be able to handle monitoring this many people for 21 days after they no longer have the flu. This will result in many people who have ebola being mistaken for having the flu, and being allowed to be in public and to spread the disease

Must read.

http://thefederalist.com/2014/10/31/medical-science-doesnt-support-official-rhetoric-on-ebola/

This year a team of researchers has already found more than 300 genetic mutations in the Ebola genome that now “make the 2014 Ebola virus genomes distinct from the viral genomes tied to previous Ebola outbreaks,” a portion of the findings reported in Science. This means that the strain of the virus that now threatens Americans (or could threaten the country a year from now) just might be transmitted with more casual contact than in the past.
15  Bitcoin / Bitcoin Technical Support / Re: How 'Anonymous' is Bitcoin? on: November 01, 2014, 07:52:06 AM
There were some papers and articles published about the deanonymization the bitcoin network and such, reading those may help you understanding how such techniques work. One of them e.g.

http://www.coindesk.com/eavesdropping-attack-can-unmask-60-bitcoin-clients/ (June 2014)
Informal description of the client deanonymization attack on the Bitcoin P2P network

"The researchers also found that the attack could be designed to prevent the use of the Tor network, which anonymises traffic. Additionally, the attack can 'glue' transactions, so that transactions performed on one machine using multiple bitcoin addresses can be grouped together."

(Also asking here, is this concept/theory correct?)
Something like this tells me that if all transactions (and hence addresses) in a wallet can be tied together, then if a single transaction reveals your identity (at any point in time), your wallet and subsequent transactions are compromised. Assuming someone is willing to invest the time and effort.


Yes, the concept/theory of a poisoned node is correct.  It is because, like Skype actually, every time you use a full wallet (like Armory) it broadcasts your IP address every time you boot up and/or send or receive (it's not clear to me which, but it's one or the other).  From this information a dedicated person can track your activities--if they have specialized software like the researchers from the paper below.  Or, as in the paper involving Tor, they can set up 'poisoned nodes' next to yours (possibly geographically located, so they are the first nodes to greet your PC when you boot up), and intercept your bitcoin communications that you think are heading to Tor, but in fact are going to the poisoned nodes.  But to do so, they need to have lots of such bad, poisoned nodes (the article mentions renting lots of servers), to trick the good nodes, which is something only either a big government agency or a very sophisticated criminal syndicate can afford to do, not your casual basement hacker.

Although numerous Bitcoin clients exist, none of them are specialized for data collection. Available clients often need to balance receiving and spending bitcoins, vetting and rejecting invalid transactions, maintaining a user's wallet, mining bitcoins, and, perhaps most detrimental to our study, disconnecting from "poorly-behaving" peers; these were precisely the peers we were interested in.  Because existing software had integrated functionality that interfered with our goals, we decided to build our own Bitcoin client called CoinSeer, which was a lean tool designed exclusively for data collection. For 5 months, between July 24, 2012 and January 2, 2013, CoinSeer created an outbound connection to every listening peer whose IP address was advertised on the Bitcoin network. We maintained that connection until either the remote peer hung up or timed out. In any given hour, we were connected to a median of 2,678 peers; for the duration of our collection period, we consistently maintained more connections than the only other Bitcoin superclient we know of - blockchain.info. This data collection effort required storing 60 GB of data per week

Hello! everyone.

I just wrote an article on liberty.me called:

The Good bad and ugly of ‪Bitcoin‬ pseudonymity. 

http://juansgultch.liberty.me/2014/10/31/the-good-the-bad-and-the-ugly-of-bitcoins-pseudoymity/

The article was lightweight, tin-foil hat stuff but it was good for the links therein, I thank you for that.

From the study below you can see how using a specialized piece of software, you can track IP addresses with bitcoin send/receives.  Note also the author can figure out how much each person has by tracking 'unusual' requests (which is somebody sending money to themselves).  The other link shows how to construct a poisoned node that will listen to and intercept your bitcoin traffic, even if you are trying to use Tor.

 Discovering Anomalous Relay Patterns
When we began analyzing our collected data, we manually looked for interesting
behavior. The following are speci c cases that led us to believe that transaction
relay behavior may be used to map Bitcoin addresses to IPs.
Case 1:
On August 31, 2012, we received a transaction from a single IP that
was never relayed again. This \single-relayer" transaction is highly unusual for
a P2P system using a gossip protocol; we would expect to have received it from
the majority of the approximately 2,500 peers we were connected to at the time.
6
On September 3, 2012, a new transaction with the same inputs and outputs was
relayed network-wide and accepted into the blockchain. Given this information,
can we assume the sole relayer of the rst transaction was its creator and thus
owns the Bitcoin addresses inside?
Case 2:
On August 22, 2012, a single IP sent us 11,730 unique transactions
within a 74-second window. The median rate we received transactions was
only
43 per minute. Because these transactions were already in the block chain, they
were not relayed by anyone else, making them \single-relayer" transactions. Us-
ing connection metadata, we saw that this large transaction dump corresponded
with this user upgrading to a newer version of the Bitcoin client he was using.
Could all of these belong to the single relayer?
Case 3:
For 52 days, beginning on July 24, 2012, we received the
same
transac-tion from a single IP approximately once every hour; no one else on the network
relayed it. The peer then disconnected, only for a new IP to connect and exhibit
the same behavior for the next 23 hours. This occurred again with the appear-
ance of a third IP, nally going silent a day later. Why would a transaction be
continually rerelayed, and what connection does it have to its rerelayers

Ah, just forget the most important reason to invest in us.

We are probably the only one honest site with investment system.


Mr. Bikini--

1) Why do you say you are the only honest site with investment system?  How would you know if the others are honest?

2) Indeed you changed your site (as dooglas suggested) so the client can randomize their own seed (I tested it now, and it works), but I have another concern:  for some reason (and it could be just chance) I get a lot of "hot streaks" when I roll the dice.  Look at my hot streaks from just a few rolls, with X < 49.5% being the payoff.  I did not play much, just a bit.

# Rolls in a row (either color, with X < 49.5%) -- Probability of it happening: (0.5)^#rolls in a row

seven -- 0.7%
four -- 6.25%
five -- 3.1%
six -- 1.6%
six -- 1.6%
five -- 3.1%
four -- 6.25%
five -- 3.1%

Is this odd?  Or just me?  ;-)

3) How about if you publish all your data for past users, in a log, with seeds, and we can test if the rolls are really random?  Also publish whether or not the gambler was betting money or not.  Because maybe the statistics change if there's real money being bet?  Or, it could be your site has a lot of "hot streaks" to attract gamblers?  Just asking.

4) I figure now you are not Russian but Italian, maybe Italian-Russian?  LOL.

Good luck with your site!

All transactions and balances are public knowledge; that's how the blockchain works. You can use a mixing service or send money to a dicesite or something then back to a new address if you don't want people to know how much you have, but you're never going to be able to truly hide your balances or transactions.

Yep..what he said.  The best way to "hide" how much YOU have is by not going on the internet and letting everyone know what YOUR bitcoin address is. Yeah, everything you do will still be recorded in the block chain, but as long as you don't make it obvious that those transactions are yours, who cares?

I see.  So that means buying bitcoin in person, or using an escrow agent?  And then using Armory or a heavy wallet that does not rely on a server to crunch the blockchain?  And possibly using a BTC-paid proxy server or VPN or Tor when receiving money or sending money through Armory?  Is that it?
