On Monday February 24th, 2014 I was invited to the offices of Coinbase in San Francisco, as part of a voluntary cross-industry effort to provide independent review of the security of Coinbase customer funds.


I am the Chief Security Officer at Blockchain, a bitcoin company that offers a web-wallet service that competes with some of Coinbase’s services. Prior to this day, I had not been to Coinbase’s offices, nor did I have any prior professional relationship with Coinbase. My visit was as an independent security expert with no financial control or interest in Coinbase. My goal during this visit was to validate the existence and security of customer funds.



During my visit, I met with the CEO and other executives and was presented with information on the mechanisms Coinbase uses to secure customer funds from theft, including their cold storage system and operating process.


I was shown an internal reporting tool used by Coinbase to verify total customer funds and the allocation of funds between the “hot wallet” and “cold storage” and funds in transit. Coinbase shared their process and technical details for cold storage, including their process to ensure funds cannot be retrieved from cold storage without the assembly of multiple keys controlled by different people.


While Coinbase publicly states that up to 97% of customer funds are in cold storage, at the time of my visit, their internal reporting tool showed that the cold storage system contained 98.8% of customer funds. To confirm for myself that these funds were in the cold storage system, I looked up the balance each of the cold storage addresses against the public blockchain, using an external site. The balance recorded on the public blockchain ledger for each of the addresses matched the balance recorded in Coinbase’s accounting system.


Although the accounting system and the blockchain balances appeared to match, I wanted to confirm that these addresses were actually controlled by Coinbase, thereby ensuring they controlled the funds. I randomly selected one of the cold storage addresses and requested that a transaction be signed to prove ownership of the address. This was not pre-arranged nor was there any warning that I would make such a request. Coinbase complied with my request and produced a transaction that proved they owned the cold storage address of my choosing.


Based on what I observed during my visit and my experience in security, it appears that the Coinbase system contains the expected funds and their cold storage system and process appear to be operating according to security best practices.

Tokyo court extends Mt. Gox bankruptcy investigation to May 9

(Reuters) — A deadline for a court-mandated investigation into why bitcoin exchange Mt.


Gox failed, and whether it should be revived under bankruptcy protection laws, has been extended to May 9, the company said in a brief statement on Friday.


The Tokyo District Court had set a Friday deadline for Nobuaki Kobayashi, a partner at Nagashima Ohno & Tsunematsu, to report on his investigation into the collapse last month of what was once the world’s largest bitcoin exchange.



In seeking the extension, Kobayashi cited the involvement of investigatory agencies as well as the work required to confirm Mt. Gox’s financial situation, according to a petition filed to the court. Mt. Gox said on Wednesday it had submitted records and documents to the Tokyo Metropolitan Police as part of its civil rehabilitation application.


Mt. Gox filed for bankruptcy protection in Tokyo on February 28, saying 750,000 bitcoins belonging to its customers and 100,000 of its own bitcoins were stolen by hackers who exploited a security flaw in its software. It also said around $27 million were “missing” from its Japanese bank accounts.


It has since said it “found” 200,000 bitcoins in an old-format online wallet which it had thought was empty, raising creditors’ hopes of recovering some of their lost digital wealth.


Mt. Gox has applied to restructure under a procedure similar to Chapter 11 in the United States. But whether the exchange will qualify for that procedure, or be forced into liquidation, will depend on the results of Kobayashi’s investigation and the approval of creditors.

Why the Bitcoin Crash Below $500?

Bitcoin crashed below $500 during opening of the Asian trading session this morning.


This is the first time since early February, during the death throes of Mt.Gox, that price action has seen these levels.


Looking for the reason why this relentless sell-off is happening, CCN brings you this incisive and original analysis, first:


People’s Bank of China



Although the PBoC pervasive ban of Bitcoin is rumored to be a rumor, the strong sell-off this morning coincided with market opening in East Asia and would seem to confirm that the market desperately fears that PBoC is about to voice strong rhetoric against the status of Bitcoin in Mainland China.


This Bitcoin crash is apparently flying in the face of the market adage that says:


“Buy the Rumor, Sell the News”


Bitcoin PBoC Wang Qishan

Wang Qishan being coached by Barak Obama

It seems that some traders have accepted the rumor of a PBoC ban as a given fact and are dumping in anticipation of a strong Chinese Bitcoin sell-off in the coming weeks. Or the majority of traders are all too aware that this is unconfirmed rumor and are buying on each lower low. Hence we see price descending in a stairstep fashion – being tugged between the fear of an imminent sell-off, on the one hand, and opportunistic buying (in case this is a rumor) on the other.


The important thing to bear in mind with market rumors is that they consistently instill fear, because as market wisdom has it, the human mind is prone to negativity and panic in the face of uncertainty. As is the case with all markets, so it is with BTC, especially with its ever-present and looming Axe of Regulation. Increasing the downward pressure on price, is the recent spate of exchange misfortunes – add these renewed regulatory uncertainties – and the jittery public consciousness is all the more understandable.


As discussed below, there is an uncanny timing to the PBoC rumour following so closely on the heels of the US Inland Revenue Service decree on the status of Bitcoin.


Update 06h32 UTC


Moments ago The Register published “Bitcoin Bloodbath as China shutters all trading sites” based on the same Caixin article linked below. Shameless sensationalism based on zero evidence.


Update 02h40 UTC


A translation of the Chinese newspaper Caixin article is made available in English and seems to confirm the rumor, yet fails to quote any official PBoC statement to corroborate the drama.


Update 02h27 UTC


reddit bitcoin huobi PBoC rumour

They didn’t? They will! When? Aw, shucks..!


Japanese Economic Data


CPI and Unemployment figures for Japan were released at market open this morning – and cooked to perfection, no doubt:


Japan economic data 28 Mar 2014

Japanese Economic Data courtesy of http://forexfactory.com

Tokyo and National Consumer Price Index figures both confirmed continuing re-inflation of the Japanese economy, which has spent the better part of two decades in a crippling deflationary spiral. Prime Minister Shinzo Abe’s controversial “Abe-nomics” strategy seeks to boost inflation via massive devaluation of the Yen, as well as tax incentives for manufacturers to export against the weaker (and therefore advantageous) Yen.


It may very well be that the prospect of improving economic conditions has swung traders’ sentiment toward Nikkei and Forex trades – leading to closure of positions held in speculative Bitcoin trades – and hence more downward pressure on the BTCUSD price.


US Inland Revenue Service


bitcoin accepted hereHere’s how Bloomberg broke the news: You go out to buy coffee. The cafe accepts bitcoin and you gladly pay the $2 bill with bitcoin. If you’re a US citizen, and you bought that bitcoin when price was at $250, you now owe the IRS $1 in Capital Gains tax. Not Happy icon sad Sell bitcoin Holdings Now.


In fact, a proper review of the US IRS publication document reveals that the ruling is only applicable to purchases in excess of $600. Well, thanks a lot Bloomberg… Then again, many useful things are payable in bitcoin, and cost more than $600. Capital Gains Tax on $600 is a lot more than CGT on $2… Not Happy icon sad Sell Bitcoin Holdings Now!

Bitcoin Markets Continue to Slide on PBOC News

As usual confusion is surrounding the most recent news out of China.


Early Thursday it was reported by multiple media outlets that the PBOC had ordered banks to close the accounts of virtual currency exchanges. At first many thought the news was just another false rumor for the purpose of depressing the market to allow a cheap buy in. It appears, however, that the reports may have been correct (including those at CryptoCoinsNews) and that Chinese domestic banks may no longer do business with websites that trade in digital currencies. According to the reports the PBOC will require the banking accounts of the various Chinese virtual money exchanges to be closed by April 15. The news was mostly discounted at first with Reddit bloggers calling it FUD and markets reacting reluctantly. However, the Wall Street Journal is also reporting this story with quotes from Bobby Lee, Chief Executive Officer of BTC China.



It is also important to note that the story has been reported as fact by the Chinese news media, including by the online business news service Caixin. The Wall Street Journal Reported that Bobby Lee, Chief Executive Officer of BTC China had stated that he had not seen the document but is concerned the reports could be true. When Bobby Lee was asked if customers would no longer be able to use banks to deposit funds he said:


“If the rumor turns out to be true, that’s what’s going to happen.”


He continued:


“At this time it’s too early for me to elaborate on what steps we will take, …We will take it one day at time.”


Though banks may no longer be able to deal directly with exchanges, it may be possible for customers to make deposits directly. Perhaps this is the reason the markets did not react with extreme price drops as seen in early December when the PBOC issued similar statements saying that banks could no longer engage in Bitcoin business. If customers are allowed to make deposits directly into the exchanges, it may represent more of an inconvenience than an actual halt to the trading. In any case, relatively speaking, the Chinese markets so far have not reacted with the same quick and dramatic price falls as previously with PBOC news. Possibly some of this has been priced in as the rumors have already been circulating.


PBOC issues new statement on exchanges

Prices slide after PBOC issues new statement on exchanges

As of the writing of this story, Bitcoin Markets are down 21% from 592 to 470. (Price was falling during the writing of this article) This fall compares to the early December drop of over 50%. Of note is the fact that, in early December, we were coming off the highs and now much of these negative news stories have already been priced into the market. It will be interesting to see how the Chinese markets continue to react to this news that cannot be positive for trading there. It should be noted that the Chinese markets are, in fact, quite important for Bitcoin so we will not see US markets reacting much better. In particular Litecoin is heavily traded on the Chinese markets.


In writing this article, it was clear that many bloggers and online commenter s seem to criticize the Chinese for the actions of their central bank. In fact, it is important to realize that many Chinese yearn for the freedom that virtual currencies represent while many in the West easily fall for Banker sponsored FUD. For example, as if the recent IRS ruling is some empirical finding, the Bloomberg article on this story repeatedly refers to Bitcoin as a commodity. More than likely the Bloomberg article represents a continued inability of mainstream journalists to understand the Bitcoin protocol and what it is about. In reality Bitcoin has many superior qualities as a transactional currency and does not do so well as a commodity. This is because its value depends so heavily on what the state might do to restrict its use, as this story is evidence of.


It is clear that the PBOC is intent on controlling Bitcoin. It will be interesting to see to what lengths they will go to in order to achieve this. Many people in China mine Bitcoin for a profit and sell and build Bitcoin mining equipment. The actions of the PBOC have cost Chinese investors a lot of money. Will the PBOC out of its own monetary interests continue to punish so many profitable enterprises?

Today in Gox: Police on the Case

Mt. Gox rose again today to announce it is now working with Japanese police to investigate what happened to the bitcoins it lost, misplaced, or had stolen by hackers.


The statement, posted on the homepage on letterhead bearing CEO Mark Karpeles’ name, said:


Following its application for commencement of civil rehabilitation, MtGox Co., Ltd. consulted with the metropolitan police department with regard to the disappearance of bitcoins which is one of the causes for said application. MtGox Co., Ltd. hereby announces that it has submitted necessary electronic records and other related documents.


MtGox Co., Ltd. intends to fully cooperate with each competent authority. Further, MtGox Co., Ltd. continues to make efforts to clarify facts as quickly as possible and to recover from damages.


The announcement is carefully worded, not mentioning whether Mt. Gox chose to consult with the police, whether the police came to Mt. Gox, or if it was just a routine matter as part of the civil rehabilitation process. According to a report by Reuters, the police do not intend to make any further statement on the matter.


Other than knowing the authorities are involved somehow, and the words “recover from damages” at the end, the update probably does little to comfort those who lost large sums of money when Mt. Gox declared bankruptcy nearly a month ago.


Rumor file


Another tiny ray of hope today came in the form of a tweet by Eren Canarslan, an investment banker from Turkey:


Within a few days(or hours) @MtGox will announce that “they found ~670.000 #bitcoin & may release some BTCs to the victims. @PatronaPartners


— Eren Canarslan (@CanarslanEren) March 25, 2014


The one-off tweet, followed by nearly a whole day of radio silence (that as of press time still hadn’t been broken) probably would have been written off as trolling or wishful thinking had it not been for these two other cryptic tweets he’d posted on 4th and 5th March:


@PatronaPartners As I heard from an insider from @blockchain: they found lost #bitcoin of @mtgox Note: It’s not an investment advice/offer.


— Eren Canarslan (@CanarslanEren) March 4, 2014


@zeroblock @PatronaPartners @blockchain I talked with Mark Karpeles, the news is good !


— Eren Canarslan (@CanarslanEren) March 5, 2014


Within two weeks, Mt. Gox announced it had discovered 200,000 BTC in an ‘old format’ wallet. In the world of lost bitcoins, this has bestowed a kind of prophetic status on Eren Canarslan, whose bitcoin-associated follower count increased markedly over the day.


It has not yet been established what his connection is to Mark Karpeles, Blockchain, or any insider information. The 4th March post drew a bemused response from ZeroBlock, Blockchain’s subsidiary.


It has also raised interest in the company he was supposedly tweeting to, Hong Kong’s Patrona Partners. That company responded by tweeting “Only thing I know he is not trolling,” with a link to an image of Canarslan’s earlier post.


We await, like a flock of seagulls around a small child, the next morsel either Mt. Gox or its claimed ‘insiders’ toss in our direction.

National Bitcoin Alternative Auroracoin Launches

As many of you read this, all the good people of Iceland will have just become about 30 Auroracoin richer, which translates to nearly $350 if current prices hold.


Auroracoin is among the first serious attempts to use a new Bitcoin-inspired crypto-currency to save a flailing European economy.


Based off of Litecoin, itself an alternative to Bitcoin, Auroracoin is the brain child of Iceland’s own Satoshi Nakamoto-like character, who uses the pseudonym Baldur Friggjar Odinsson. While it launched in February, things will get really interesting when it officially begins to get distributed to the 330,000 citizens of the island nation on midnight local time on March 25. The distribution process has been dubbed an “air drop” and will take place in stages over the next year, during which time each citizen is basically allowed to claim a total of 31.8 Auroracoin.


As of this writing, just as the air drop is set to begin, Auroracoin has the fourth-largest market cap of any crypto-currency, with each coin valued at .02 bitcoin or about $11.60. That price has been falling over the past twelve hours leading up to the air drop, and it stands to reason that the price could really collapse once a significant number of Icelanders begin to flood the market by trading away what is basically a gift of crypto-currency, particularly since it’s not clear where Auroracoin can be spent.


Each citizen of Iceland is entitled to a little more than 30 Auroracoin over the next year.


Auroracoin’s biggest weakness could also be the thing that keeps its price from crashing, at least in the short term, and that’s the fact that it’s not very widely known at all, even in Iceland. It is, however, in the radar of Iceland’s government — a Parliamentary committee held a closed-door, off-record meeting on the currency earlier this month.


The Forbes E-book On Bitcoin

Secret Money: Living on Bitcoin in the Real World, by Forbes staff writer Kashmir Hill, can be bought in Bitcoin or more traditional currencies.

Auroracoin is a direct response to the strict capital controls imposed by Iceland’s government, which still make it difficult to move money in and out of the country today, more than five years after they were implemented as a temporary reaction to the financial carnage of 2008. As Odinsson puts it in a manifesto of sorts on the Auroracoin site:


This means that the Icelandic economy is slowly bleeding. The people of Iceland are being sacrificed at the altar of a flawed financial system, controlled by an elite that made astronomical bets supported by the government on behalf of the people and ultimately at the expense of the people.


“The whole point of auroracoin is to provide Icelanders with an alternative to the króna, a currency they are forced by pain of imprisonment to use,” Odinsson told the Wall Street Journal recently. “Icelanders will be free to sell auroracoins anywhere they like and buy anything they like, be it dollars or other foreign currency on offshore currency exchanges. They won’t need permission from the Central Bank or politicians.”


While Auroracoin’s success remains uncertain, crypto-currency fanatics in at least one other European nation will surely be watching closely. Spaincoin, another digital currency with nationalistic ambitions, has announced it’s plans to launch a similar distribution of coins to Spanish citizens in April.


UPDATE (10 p.m. EDT): The Auroracoin site has been nearly impossible to reach since the moment the air drop began two hours ago. However, at least a few Icelanders are already reporting that they were successfully able to claim their coins. The price of Auroracoin has actually increased by over 15 percent as of this moment.



auroracoin begins cryptocurrency ‘airdrop’ to whole of Iceland


One country in Europe that may benefit from a widely-adopted alternative currency, free of central bank constraints, is Iceland, whose entire population — around 300,000 — has just been given a one-off 31.8 unit bag of the fledgling digital currency auroracoin.


Iceland was praised for not bailing out the country’s banks following the country’s 2008 financial collapse, but according to the founders of auroracoin — a new currency based on Bitcoin derivative Litecoin — some of its other responses, such as strict capital controls that are imposed by Iceland’s Central Bank are “slowly bleeding” the local economy.


“These controls were supposed to be ‘temporary’, but as with so many government actions, they remain in place to this day,” said auroracoin’s founder, who goes by the pseudonym Baldur Friggjar Odinsson.


“This means that the people of Iceland have, for the past five years, been forced to turn over all foreign currency earned to the Central Bank of Iceland. This means that the people are not entirely free to engage in international trade. They are not free to invest in businesses abroad.”

So, today, in a bid to escape these controls Odinsson and co “airdropped” 31.8 Auroracoin to every citizen of Iceland, which they can claim at any time over the next year. auroracoin used Iceland’s publicly available national ID database to allocate the payment to citizens and according to a post by auroacoin on Twitter, 2,600 people have claimed their airdrop in the past 12 hours .


auroracoin, which launched in February, earlier this month briefly became the second largest alternative currency by market cap to Bitcoin (excluding the centrally-managed currency Ripple), according to a report by the Wall Street Journal .


With 10.6 million “pre-mined” coins available, auroracoins were worth $39.71 each with a market cap of $381m, briefly putting it ahead of Litecoin’s $423m market cap and Bitcoin’s $8bn for the metric.


But as with other cryptocurrencies auroracoin has seen large fluctuations in its price, and today, any Icelander that wishes to exchange it for US dollars would only get $11.41 per unit. Then again, as Odinsson points out, Iceland’s currency, the krona, has been dramatically devalued relative to the US dollar over the past few decades.


auroracoin’s market cap today stands at $121m, according to Coinmarketcap , which still makes it much higher than Peercoin, Dogecoin, and dozens of others.


After the airdrop, anyone interested in acquiring auroracoins will have to mine or trade them. The initial airdrop was done in the hope of spawning a viable alternative to the local krona.


If adopted, the new currency may provide a partial solution to obstacles that local businesses have in attracting foreign investors.


“[The capital controls have] had a crippling effect on foreign investment, as foreigners in general avoid investing in Icelandic enterprises, because of the risk of not being able to convert their investment back into dollars or euros,” Ordinsson said.


But Iceland’s Central Bank has warned that while it’s up to Icelanders whether they choose to use auroracoin for domestic transactions, use it for cross-border transfers of foreign currency would be illegal under its Foreign Exchange Act.


“The Bank is of the opinion that there is no authorisation to purchase foreign currency from financial institutions in Iceland or to transfer foreign currency across borders on the basis of transactions with virtual currency. For this reason alone, transactions with virtual currency are subject to restrictions in Iceland,” it said this month .

Evidence That Transaction Malleability Did Not Bankrupt Mt. Gox

Solid research has proven what many bitcoiners have long suspected; transaction malleability did not play a significant, if any, role in the disappearance of 850,000 BTC from Japanese exchange Mt. Gox.


Christian Decker and Roger Wattenhofer of ETH in Zurich, Switzerland, combed through the blockchain to tally each instance of a potential transaction malleability attack in order to figure out exactly how much Bitcoin was put at risk by the alleged attacks.


Their research concludes:


The transaction malleability problem is real and should be considered when implementing Bitcoin clients.



However, while MtGox claimed to have lost 850,000 bitcoins due to malleability attacks, we merely observed a total of 302,000 bitcoins ever being involved in malleability attacks. Of these, only 1,811 bitcoins were in attacks before MtGox stopped users from withdrawing bitcoins. Even more, 78.64% of these attacks were ineffective. As such, barely 386 bitcoins could have been stolen using malleability attacks from MtGox or from other businesses. Even if all of these attacks were targeted against MtGox, MtGox needs to explain the whereabouts of 849,600 bitcoins.


Of course, 200k BTC was inexplicably “recovered” from a misplaced “old format” wallet earlier this month, which still leaves 650k missing.


If transaction malleability did not result in the loss of 650,000 BTC, then why would Mark Karpeles make up such a story? Some have posited that he is under a “gag order” placed on him by a law enforcement agency investigating drug operations connected to the Silk Road busts, an investigation that has supposedly seized the bitcoins in cold storage.


Such an investigation would not be permitted to cause the exchange to file bankruptcy. The fact is, it will be a long time before the community will actually know what happened to that 6% of all Bitcoin.


Decker and Wattenhofer also discuss the nature of the widespread halting of withdrawals by many service providers following Mt. Gox’s:


Assuming MtGox had disabled withdrawals like they stated in the first press release, these attacks can not have been aimed at MtGox. The attacks therefore where either attempts to investigate transaction malleability or they were aimed at other businesses attempting to imitate the purveyed attack for personal gain. The sheer amount of bitcoins involved in malleability attacks would suggest that the latter motive was prevalent.


It remains questionable whether other services have been informed by MtGox in time to brace for the sudden increase in malleability attacks. Should this not be the case then the press release may have harmed other businesses by triggering imitators to attack them.


The facts presented in the publication bring a new level of dismay when thinking about Mark Karpeles’ comments regarding how people should be thankful for Mt. Gox acting quickly to bring transaction malleability to our attention.


And there is still the question of what exactly happened to Silk Road 2 when they claimed to lose funds to transaction malleability.


Should any further information come to light regarding this, we will be sure to bring it to you here in a new article here on CryptoCoinsNews.


original report:


Bitcoin Transaction Malleability and MtGox



Christian Decker, Roger Wattenhofer

(Submitted on 26 Mar 2014)

In Bitcoin, transaction malleability describes the fact that the signatures that prove the ownership of bitcoins being transferred in a transaction do not provide any integrity guarantee for the signatures themselves. This allows an attacker to mount a malleability attack in which it intercepts, modifies, and rebroadcasts a transaction, causing the transaction issuer to believe that the original transaction was not confirmed. In February 2014 MtGox, once the largest Bitcoin exchange, closed and filed for bankruptcy claiming that attackers used malleability attacks to drain its accounts. In this work we use traces of the Bitcoin network for over a year preceding the filing to show that, while the problem is real, there was no widespread use of malleability attacks before the closure of MtGox.

Build a P2Pool Node

P2Pool is a decentralized mining pool that consists of a network of peer-to-peer miner nodes that anyone can mine or expand.


This guide will show you how to install the P2Pool software, create your own P2Pool node, and join it to the P2Pool network.


We will be using a fork of the original Bitcoin p2pool software, called zen2pool, that has been optimized for scrypt- and progressive-N scrypt-based altcoins. If you would like to install the Bitcoin specific node software, then use forrestv’s version (instead of zen2pool) and substitute references to ‘zen2pool’ with p2pool throughout the rest of this guide.


If you want try P2Pool by just mining at an existing pool, rather than installing and configuring your own node, the see the Test Drive P2Pool guide.


Requirements


This installation process is illustrated with Ubuntu Linux and Execoin, although the latter can be substituted with any other coin such as Anoncoin or Litecoin. It is assumed that you already have a local instance of the coin daemon running with the following parameters:


$ ./execoind -daemon -server -rpcallowip=127.0.0.1

The P2Pool software will later connect to execoind in server mode and will relay mining software RPC communication via the localhost.


If you don’t have the execoind daemon, then you can fetch it from GitHub, compile and start with the command above. Execoin source code is available from GitHub with:


$ git clone https://github.com/execoin/execoin.git


Install Linux package dependencies:


$ sudo apt-get install git python-zope.interface python-twisted python-twisted-web

Now clone the zen2pool source code from GitHub to a local directory (git will automatically create the source directory):


$ git clone https://github.com/venzen/zen2pool.git

Change into the directory and have a look around:


$ cd ./zen2pool

$ ls -l

Build the Scrypt modules


Both the generic and progressive-N scrypt modules are included in the py_modules directory. Let’s build both while we’re at it:


cd py_modules


cd litecoin_scrypt

sudo python setup.py install


cd ../vertcoin_scrypt

sudo python setup.py install

Start the node


Ensure execoind is running as described above and that a RPC username and password are set in the execoin.conf file that execoind would have prompted you to create upon the first run:


$ cat ~/.execoin/execoin.conf

rpcuser=execoinrpc

rpcpassword=

Make sure you’re in the zen2pool application root directory. We’re going to start zen2pool with the following parameter:


–net execoin_zen

–net tells zen2pool to use the ‘execoin_zen’ definition listed in the file p2pool/networks.py


Execute the complete command:


$ python run_zen2pool.py –net execoin_zen

P2Pool node gardenYou should see zen2pool start up and connect to execoind as well as the wider P2Pool network.


If zen2pool complains about “bitcoind taking a long time” – this is a generic message warning that zen2pool cannot make a connection to the coind daemon. Make sure execoind is running and that you are not passing it a -maxconnections= parameter. Stop and restart zen2pool.


If you see the message “Success” and lots of messages with “???” declarations, don’t worry, this is normal – zen2pool is bootstrapping the sharechain, and we have yet to point a miner at this node. Bootstrapping can take anywhere from a few minutes to an hour.


Web Statistics


p2pool web interface


Test your zen2pool web interface by pointing your browser at


http://127.0.0.1:9173


Alternatively, if you’re running zen2pool on a remote server/VPS, substitute 127.0.0.1 with the remote IP address.


Once the sharechain has finished downloading, stop and restart zen2pool. At startup, it will display its progress loading the sharechain from its local disk cache and then indicate that it’s ready for mining by displaying empty local P2Pool stats but a non-zero global hash rate. Startup your mining software and once it has submitted work for about an hour, the statics will be meaningfully populated, and you can monitor your mining in relation to the wider P2Pool network as well as other useful metrics.


Mining your P2Pool Node


You now have the option to point your mining software at your P2Pool node, as well as invite other people to mine the pool.

P2Pool Mining: What You Need To Know

Background


The harnessing of graphic card GPUs pushed mining rates to Gigahashes per second, and recently, the development of ASICs made Terahash rates possible.


Many miners either fell out of the race or were forced to form pools – combining their hashing power in order to mine profitably. So began the era of the mining pools, behind whose power to make or break small altcoins, lay a greater threat: the 51% Attack. More on that later.


The sheer hashing difficulty and cumulative network hash rate of the Bitcoin (and now many other cryptocurrencies) network makes pooled mining a necessity. Whereas much negative publicity surrounds the traditional pools, it must be emphasized that reputable mining pools do exist. One such pool, Eligius, predates P2Pool and was created by Bitcoin core developer Luke-Jr, whose vested trust and community standing guides Eligius operations.


With many other traditional pools, however, this degree of responsibility cannot be assumed, and pool operators have been known to skim payments or even abscond with miners’ funds. Attacks on traditional pools are also frequent due to the lure of fat payroll wallets accumulating there between block pay-outs. Other times, miners may simply want to setup their own pool and control their own mining operation.


This article explores a secure and miner friendly pool implementation that allows profitability while enhancing cryptocurrency networks in many integral ways.


What is P2Pool?


P2Pool is a decentralized mining pool implementation that provides mining operators with a secure, flexible and highly customizable mining platform. The P2Pool network is made up of interconnected nodes – each node representing a mining operator who is running the p2pool software.


Collectively, nodes are connected in a peer-to-peer network arrangement, much like the Bitcoin network itself. There is no hierarchy of greater or lesser nodes, and network state information is shared between nodes. Because blocks are effectively being mined on different nodes across the network, the P2Pool network is said to be “decentralized“. Decentralization a Good Thing for cryptocurrency networks because it enhances security and promotes wider distribution.


Participation


Open Source BitcoinMiners can choose to mine on any public P2Pool node, or they can setup their own node and join it to the P2Pool network. To join the network (i.e. become a node), a miner simply runs the p2pool software on a networked host and then points their mining software at the p2pool instance. There is no fee or registration for setting up a node and the software is free and Open Source. In addition to being inherently secure and customizable, at least one study suggests that – in its default configuration – P2Pool provides miners with a statistical advantage over most traditional pooled mining and, specifically, solo mining.


Even so, P2Pool has characteristics of both solo mining and pooled mining. As with solo mining, the node operator is in charge of their own mining operation with the freedom to configure it as they see fit. Similar to pooled mining, block rewards and network transaction fees are shared amongst all contributors to the pool.


It should be pointed out that, when a miner mines on someone else’s public node (as opposed to setting up their own node), they are sacrificing the greater benefit of network decentralization and could make themselves vulnerable to all of the disadvantages of traditional pools. This is not to say that a group of miners shouldn’t mine the same node, but there is the matter of the greater good for the network and issues of trust involved. Miners should determine this for themselves.


Mining Work


p2pool web interface

p2pool web interface allows miners to monitor progress and statistics

A P2Pool node provides connected miners with low difficulty work. Upon completion of each portion of work, the miner is awarded a pool share. Shares are communicated among P2Pool nodes and assembled into a sharechain – just like the Bitcoin network assembles blocks into the blockchain.


Once the pool finds a block, all contributors are paid directly, according to their shareholding as reflected in the sharechain. Payment is issued by the sharechain and without third party involvement.


Shares and Payment


The notion of ‘shares’ informs all P2Pool mining production and payment. P2Pool enables all connected miner nodes to combine their hash rates and collectively work on creating a transaction block. Each node earns mining shares according to their percentage contribution. Once the mining pool successfully solves a block, each contributing miner is paid their share of the total block reward and associated transaction fees. P2Pool implements a PPLNS reward system and payment always goes directly to a miner’s wallet – not into a central fund or holding account. Because of this transparency and equitability, P2Pool can, therefore, offer node operators immunity to the theft and corruption that clouds centralized pools.


Security


Because information about the P2Pool network, such as share-ownership, block creation progress, and so forth, is stored in the distributed sharechain, there is no single point of vulnerability. No single node can be disrupted in order to compromise the network state. This is a direct benefit of the decentralized design of peer-to-peer networks.


In the event that a node is compromised, there is no mining data to steal or destroy, since all mining shares and payout information related to that node are preserved in the public sharechain. The node operator can reinstall the node, rejoin the network and regain share and state information from the sharechain within minutes.


P2Pool node representation

Representation of the Bitcoin P2Pool node network. Larger nodes have more hashing power.

Another example of how decentralization protects P2Pool is illustrated by the all too familiar DDoS attack. P2Pool is said to be DDoS tolerant:


Whilst a denial-of-service attack does not need to disable all nodes in a network to be effective, in the case of P2Pool there is salvation in the survival of at least one node. A well-orchestrated DDoS attack can disable most (and possibly all) nodes in the peer-to-peer network, yet if only a single node survives – and is able to maintain the sharechain – it can allow the entire pool network to be rebuilt.


This means that the P2Pool network and its most important cargo, namely blocks destined for the blockchain, is more secure in the hands of a distributed network than it would be with a centralized network. Compromise of a central node (or nodes) halts all production and the state of the network is destroyed and most likely lost. This is part reason why the Bitcoin network is based on a peer-to-peer model.


With a centralized pool, there is the possibility that the pool’s combined hash rate exceeds 50% of the entire network’s hash rate. This scenario makes the protocol vulnerable to blockchain manipulation by such a mining cartel, in what has been dubbed the “51% Attack“. In contrast, a decentralized mining pool does not impose it’s combined hash rate directly on the protocol network, and hence cannot manipulate the blockchain in a fundamental way.


Practically, this means that even if 100% of miners were to use P2Pool, there is no take-over risk to the Bitcoin (or any other cryptocurrency) network. In fact, this scenario would mitigate the risk of a 51% attack on the cryptocurrency network.


Secure, more profitable, easy to use. The P2Pool network is live and well, and pools have been established for almost every cryptocurrency out there. Suitable for beginning miners, seasoned 49s and mining operators, the protocol platform is evolving every day and adoption is growing fast.

P2Pool – Higher Mining Profitability

This tutorial will show you how to connect a miner to P2Pool nodes for various cryptocurrencies.


What To Expect


We will select a suitable coin to mine, pass the correct parameters to the miner software and earn shares for pay-out. It is suggested that you run your miner for at least 24 hours to gain maximum shares and know-how from this test drive.


Initially, it will seem as if your mining is not achieving much, but be patient. After an hour or two, you will see your mining shares start accumulating, and some pay-outs should arrive in your wallet after 3-6 hours. This lag is due to the manner in which P2Pool eases your miner into the sharechain at the optimum difficulty setting, as well as the way in which share accumulation gradually builds momentum in P2Pool.


If you decide to stop mining after 24 hours, you will notice that you continue to receive payments on your shares for several hours or even days. It is a slow-but-steady game of patience, and you can expect periods of slow pay-out to be followed by periods of rapid bounty. This is the effect of variance in P2Pool.


The process is similar to mining at a traditional pool, except that there is no registration or login required. You will simply be pointing your miner software at an IP address:port and passing the wallet address (to which you would like to receive payment) as your username. A random, meaningless password is required by the mining software but is not used by P2Pool. For example:


cgminer –scrypt -o http://www.guugll.eu:11327 -u mywalletaddress -p pass


Mining Hardware and Software


Most GPU and ASIC hardware is suitable for P2Pool mining. It is even possible to profitably CPU mine some altcoins with P2Pool! Many miners find that their GPU hardware performs better with P2Pool if they scale back intensity, so experiment with that and see what works best for you. Let’s select a suitable coin for your mining tools.


Connect Your Miner and View Stats


http://www.guugll.eu:11327/static/


You will need a wallet address to pass to the P2Pool node so it can pay your mining shares each time a block is found. Adapt the above miner command line instructions if you’re not using cgminer. Remember that if you’re intending to mine Execoin then you will need to download a scrypt-N capable version of your miner from the Execoin website.


Start your miner and then point your web browser to the same node address and port as used by your miner. You should see the node statistics page which varies from plain text on some nodes to auto-updated graphic displays on others.


p2pool web interface

p2pool web interface allows miners to monitor progress and statistics

Local rate is the hash rate of the node – if you’re the only one mining it should equal your miner’s hash rate


Pool rate reflects the hash rate for the entire pool of connected nodes. This can be a sizable figure but don’t let it intimidate you. P2Pool evens the playing field for all miners!


Shares are accumulated as your miner successfully completes work given to it by the node. Orphan and Dead shares result whenever you’ve successfully submitted work, but were beat to the task by another miner solving the same pieces of work. When you first connect to a node, these tend to increase while the node adjusts your work difficulty. The rate of orphaned and dead shares usually subsides after an hour of mining.


Expected time to share is, as it says, an ETA on your next share award.


Share difficulty is a node specific calculation that shows the average difficulty of work being given to miners on that node. It will always be lower than the coin’s actual difficulty, since this the P2Pool software combines lots of low difficulty work into a higher difficulty block solution.


Expected time to block is an estimate and sometimes miners will find a block after a longer time than stated by this figure – and sometimes much faster. This is where the mysterious and variable element of “Luck” comes into play.

Feathercoin Emerges as Arbitrage Powerhouse

BitcoinIntel analysts advise cryptocommodity investors to keep their eyes on Feathercoin (FTC) over the next month, as the altcoin has been quietly gaining traction and swelling in value on major exchanges such as BTC-E.com.


While the market rates of crypto-to-USD continue to fluctuate with extreme volatility and are subjected to the whims of global events, market fluctuations between crypto-to-crypto commodities are more predictable, less dramatic, and more profitable within shorter periods of time. Traders and automated arbitrage bots have been observed engaging in frequent trades between cryptocommodities, specifically BTC/LTC/FTC. The sole purpose of flipping crypto-to-crypto in this manner is to increase their physical holdings. Many of these investors see cryptocurrency as having significantly more value than USD, and as a result hedge in altcoins like FTC as opposed to USD.

Small Units, Large Gains

At the time of writing, 1 FTC is priced at .00046 BTC, equivalent to about $0.38USD, according to the BTC-E exchange.

Within the last 30 days, Feathercoin rose to from 0.00040 BTC to 0.00128 BTC on Novemer 30, 2013. Traders who bought in using BTC at 0.00040 on November 27, 2013 saw a 278% ROI if they sold on November 30, 2013. Within the last few days, the market rate has slowly deflated back to the 0.00040 range. The Feathercoin market is anticipated to experience similar spikes and dips over the next few weeks as global events are announced related to Bitcoin and Litecoin. The current dip is being interpreted as parabolic by BitcoinIntel analysts, creating a temporary bear market that can yield significant profits for those with resources to diversify into Feathercoin via BTC-E before the market swings back to the .001+ range. The FTC/BTC fluctuations are available at CryptoCoincharts.info.

“If the value of Bitcoin drops by 500% overnight, it won’t matter to smart investors because they hedged in FTC instead of USD. At the end of the day, they still have cryptocurrency,” stated Alexander Heid, co-founder of BitcoinIntel.com and CEO of HackMiami. “FTC can always be traded for another kind of crypto if needed, or it can be spent on a good or service. The only losers in the cryptocurrency arbitrage game are those who rely exclusively on USD as a safe haven for market fluctuations. If markets don’t move in the anticipated direction, the trader can end up taking a significant hit and be left holding a USD voucher code for an exchange that they now have to figure a way to turn to cash. Keeping trades within the realm of crypto-to-crypto allows for quick and easy withdrawal, eliminates regulatory requirements, and keeps wealth within the cryptocurrency economy and stays true to Agorist principles.”

About Feathercoin

Feathercoin (FTC) was released in April 2013 as an open source fork of the Litecoin (LTC) cryptocurrency project. FTC was added to the BTC-E exchange in May 2013. Feathercoin has emerged to be considered one of the most prominent ‘altcoins’ behind Litecoin, and has a very active development community continuously maintaining the codebase. FTC operates much like LTC because it uses Scrypt as its primary encryption algorithm. However, it is designed to be more lightweight (hence the image of a ‘feather’), less resource intensive, and has the ability process transactions at greater speeds using a smaller blockchain. The Feathercoin concept and code was first developed by Peter Bushnell, who was a minor contributor to the Litecoin project.

About BitcoinIntel.com

BitcoinIntel.com, a subsidiary of HackMiami, is the first customized cryptocurrency intelligence service providing aggregate marketplace information and open source intelligence (OSINT) data sourced from exchanges, mainstream media, alternative news sources, and social networks.

BTC-e Enables Fund Withdrawals Using MasterCard and Visa Cards

Notoriously tight-lipped bitcoin exchange and CoinDesk Bitcoin Price Index member BTC-e is now allowing customers to withdraw funds to Visa and MasterCard debit and credit cards, with some exceptions.


The company blog post, issued on 21st March, indicated that the new program is now available to customers in any country, using any currency. All customers will pay a 5% fee for the service.



The new functionality is noteworthy as it will allow customers to send money to debit and credit cards issued by two of the largest and most commonly used international card issuers. At present, the transfer of funds is only possible in US dollars.


Explained BTC-e:


“If your card is not in USD, the money will be converted at the rate of VISA / MasterCard or your bank’s rate (depending on the agreement with your bank).”


BTC-e estimated that customers will need to wait between two and four days to receive funds. MasterCard’s Maestro debit card, cards issued by PayPal and Visa Electron debit cards are not able to be used in conjunction with the service.


BTC-e did not respond to requests for further information.


Customer feedback


BTC-e conducted customer testing for an unidentified period before enabling the service, and posted answers to three frequently asked questions.


The exchange indicated the transactions will display as “affiliate payment” or “refund affiliate payment” on credit card statements. It added that funds can be sent to cards in any country and that on some cards such transactions would not be possible due to restrictions imposed by banks.


Added BTC-e:


“Some credit cards that do not allow [you] to have a positive balance cannot be funded. If payout to your card is not possible, then we will immediately notify you and refund the money back to your account.”


Renewed activity


The news follows what appears to be an increasingly active period of experimentation from the major exchange in regards to its offerings, notably following the insolvency of its one-time major competitor Mt. Gox.


On 28th February, it cut withdrawal fees via some of its third-party services in a move that increased the ease with which some customers would be able to move funds out of the exchange.


The moves also come in the wake of increasing attention from the mainstream media and warnings from major investors about the exchange’s practices.

Fake China Bitcoin Ban pushes BTC price down

Update: it seems there was a document, saying People’s Bank of China is looking into strengthening regulations.


A ban on Bitcoin is definitely not part of it. The story is still developing, we will keep watching this closely.


Bitcoin price has been dropping significantly since yesterday. Markets were responding worried after being told the People’s Bank of China released a statement in which they stated all Bitcoin transactions should cease after the 15th of April 2014.


Banned by April 15


The People’s Bank of China didn’t hesitate to share its opinion about the virtual currency in the past. In December 2013, it barred financial institutions from handling Bitcoin transactions, moving to regulate the virtual currency after an 89-fold jump in its value sparked a surge of investor interest in the country. This made Bitcoin price take a fall that was over 20%. Bitcoin took a dive below $1000 on most exchanges. A lot of people interpreted this statement as if China was to ban the cryptocurrency altogether. In reality, the People’s Bank of China said “it isn’t a currency with “real meaning” and doesn’t have the same legal status. The public is free to participate in Internet transactions provided they take on the risk themselves.” After clarifying this, dust settled and Bitcoin price became relatively stable again.


With the Mt. Gox saga still going on, nobody would be surprised the People’s Bank of China would make a public statement again. After all, people might have forgotten their previous warning, time for a new one. Last night, a new statement was rumored to be released. Rumored, because there was no foundation whatsoever for this. Nevertheless, people obviously panicked as was reflected in another Bitcoin price drop. The virtual currency was slowly climbing back up towards $650 but took a dive below $600 again.


As for the statement itself, it didn’t look like a warning this time, but more like a definite ban. The People’s Bank of China would have stated that it decided to ban all Bitcoin transactions, effective as of the 15th of April 2014. It’s clear that this isn’t just an every day warning. A ban on Bitcoin transactions causes real panic. So what was actually said? Nothing, it seems…


Hoax


Sina Science and Technology got in touch with a number of representatives of different Chinese Bitcoin trading platforms. The news about the ban supposedly was issued in a document to the exchanges on the 18th of March. This document contained the message that by April 15, at the latest, all Bitcoin transactions are to be stopped. However, no exchange received any form of legal document. They assured that trading is going on, and there’s no intention to stop any services after April 15.


The People’s Bank of China declined to comment on this news, which indicates that this probably was a hoax indeed. So who did throw this message into the world? Maybe somebody who wanted to see a significant drop in Bitcoin prices so he or she could buy in cheap. If so, the strategy worked. Bitcoin is trading at about $570 now, being over $600 only a few hours ago. This kind of manipulation is not what Bitcoin was made for.


You can check the statement and the exchange’s response to it here. It’s in Chinese, so Google Translate is your friend.


Update: it seems there was a document, saying People’s Bank of China is looking into strengthening regulations. A ban on Bitcoin is definitely not part of it. The story is still developing, we will keep watching this closely.

Mt gox ‘Discovery’: US Lawyers not convinced.

Mt gox’s announcement, yesterday, that it had ‘Discovered’ an old format wallet containing almost twenty-five percent of the missing bitcoins is being viewed as highly suspect. The bankrupt exchange has found the missing coins at a time when many are paying careful attention to blockchain transactions. Indeed I wrote on this myself on March 9th in an article entitled “$113 Million of missing bitcoins may be moving through blockchain.” Mt gox has announced that they immediately informed the relevant authorities of the substantial recovery, however, one man isn’t quite buying their story.


Chris Dore is a partner at a law firm involved in representing clients in a US class action against the bankrupt exchange. His firm Edelson Law is currently investigating events up to the collapse of Mt gox, and it is Dore’s belief that the announcement is merely an attempt to stem a growing suspicion that these bitcoins were being prepared to be broken into smaller wallets and then further dispersed. He stated: “Their statement that they found (these bitcoins) in a random wallet and failed to tell anyone for two weeks is highly suspect.” He went on to state that it was his belief that these were probably the 180,000 that had been discovered moving through the blockchain on or about the seventh of March. This was reported in Cryptocoinnews on March 9th.


Chris went on to further state: ” We believe that that we were on the right trail. It appears that these 180,000 to 200,000 bitcoins were being tumbled. That they were being broken down and reconstituted so our goal was to find this out.” Dore seems to believe that declaring these funds to be discovered may be a ploy to hold up further investigations into the missing funds. Dore went on to say: “If it’s a coincidence, it’s a $120 Million coincidence. We frankly just don’t buy it.”


Edelson Law yesterday applied to the courts for a relaxation of the restrictions on Mt gox assets in order to make it easier to investigate their transactions and help to seek to ‘discover’ further funds. Dore is quite skeptical about the motives at Mt gox stating that: “they found it in a wallet and they were breaking it down into hundreds of thousands of smaller wallets, it raises a lot of questions about their honesty and whether they are being forthright about what they have.” Dore was unwilling to state exactly how much he knew, but he seemed to believe that it would have been interesting to track the transactions to see where they would finally end up. Interestingly the investors that have lost funds are not currently being treated as creditors within the bankrupcy hearing and Mt gox is attempting to have it’s US assets shielded until the conclusion of it’s bankruptcy hearings in Tokyo. The next court hearing, is scheduled for April 1st in Japan. Let us only hope that the date chosen is not indicative of their attitude towards their clients. This may be a futile hope in an organisation that has treated it’s investors with an attitude of nothing less that open contempt. Cryptocoinnews will keep you appraised of developments.

MtGox Recovery Initiative

We are a group of people who have lost considerable funds on MtGox, due to Mark Karpeles’s completely irresponsible actions.


We have retained a very good Japanese law firm, which will try to recover as much as possible, and additionally press criminal charges against Mark Karpeles personally. Karpeles was holding customer deposits on his company bank account, which is illegal in Japan.


To gain additional proof and insight into the extent of the criminal acts committed by MtGox and Mark Karpeles, we are building a database of losses. Please fill out the form below to help build our case.


Additionally you can indicate if you would like us to try to get your funds back also. This is no legal commitment at this point, just informational. Once we gain more insight in our ability to do so, we will contact you to inform you of any further possible action.


MTGOX RECOVERY UPDATES

Update #1


Hi Everyone,


This is our first update since we started the website. The response has been overwhelming. Our site http://www.mtgoxrecovery.com now represents over 20% of all MtGox claims and is still growing rapidly. This is great for several reasons, but first I would like to share some more information about who is behind this site.


My name is Olivier Janssens, I recently received some press by taking the first flight paid for with bitcoins(*) I have been an early miner since 2010, and (still) believe Bitcoin is the greatest invention since the Internet. This is the currency of the People, and will allow us to regain much freedom, and enhance our way of doing business together in ways that we have never seen before. Unfortunately, as part of the growth process, some of the rotten apples have to be weeded out. In this case the apple was quite big.


I personally lost over $5 million USD in this debacle, due to Mark Karpeles stating to me personally that large amounts of Bitcoins could be sold on his exchange without any issues. After 3 months of trying to (unsuccessfully) extract my money, I started preparing a lawsuit. This was about three weeks ago, and around the time the first protestor arrived at their office because MtGox had stopped sending Bitcoins under the excuse of the malleability bug.


Mark knew I was a major stake holder in the Bitcoin community, and we discussed solutions for 3 hours to try to resolve this. At that time he kept telling me he could only send me a very limited amount per month, due to anti money laundering issues. Obviously, this was a lie.


MtGox was already insolvent at that time and likely was long before then. Mark had lured me (and many others) into sending over millions worth of Bitcoins so he could continue whatever scam or scheme he was running. However, I decided that I would not take MtGox down with my lawsuit (I was ready to have their bank account blocked and start criminal charges against Karpeles personally).


The reason why I didn’t proceed with that course of action was because I wanted to protect the community from being harmed by taking down its oldest exchange. So I decided to take Mark’s word that he really had anti money laundering issues, and bought back in. In the end I walked away with a mere 20% of my original investment (bitcoinbuilder).


This was a huge loss, but I still have Bitcoins left. There are many people who have lost their entire life savings due to Mark Karpeles’s criminal behaviour. Personally, I do not believe that the coins were leaked through a bug. I believe this scheme has been going for much longer. Mark will be investigated for his potential crimes. He is in Japan and the legal team I have on this case have assured me that he is unable to leave the country due the chapter 11 filing.


This brings us to our progress so far. In the last days we have been working hard on assembling evidence from people who have been ripped-off by Mark in one way or another. Not just by depositing coins on the exchange, but by false promises made by him personally. If you have any such story where you communicated to him personally and where he gave you guarantees, please forward it to contact@mtgoxrecovery.com. Any additional evidence which might help prove that Mark is behind this is very welcome. If you have other evidence that would show something different, please send it to us also. We are making a timeline of events, and a very clear document, and will be communicating this together with any other info we gather to the police.


Meanwhile, we have also started some initiatives like http://www.projectgox.com — an idea that will start a community based bitcoin exchange, where all the people that lost money in MtGox become shareholders and take part in the profits. We think that the Bitcoin community is extremely strong and resilient, and that we look out for each other. This is what makes us strong.


So far I have been funding this whole lawsuit personally, and I do not want to take donations because I think everyone has lost enough. I believe Bitcoin is too important to have something like MtGox kill this valuable community.


We will grow from this and become much stronger than before. Together, we will try to make right what was done wrong, and start initiatives to make people whole again. We will soon reach over 50% of the Plaintiffs, and this will allow us to take control of the former MtGox.


I welcome any ideas on how to monetize this again so we can start making back what we lost. In the next days I will bring forward the best ideas we have received, and then we can all vote on how we wish to move ahead. I do not have much hope on recovering any ‘stolen’ bitcoins, but we will do our very best to investigate this to the fullest extent of the law, to find out exactly what happened, and to bring those responsible to justice.


Regards,

Olivier Janssens

MtGox finds 200,000 missing bitcoins in old wallet

Bankrupt Japanese firm MtGox said in a filing that it has found 200,000 lost bitcoins.


The firm said it found the bitcoins — worth around $116m (£70m) — in an old digital wallet from 2011.

That brings the total number of bitcoins the firm lost down to 650,000 from 850,000.

MtGox, formerly the world’s largest bitcoin exchange, filed for bankruptcy in February, after it said it lost thousands of bitcoins to hackers.

“MtGox had certain old-format wallets which were used in the past and which, MtGox thought, no longer held any bitcoins,” said Mt Gox chief executive Mark Karpeles in the filing.

However, “on March 7, 2014, MtGox confirmed that an old-format wallet which was used prior to June 2011 held a balance of approximately 200,000 bitcoins,” he said.

Mr Karpeles said the firm moved the found bitcoins to offline wallets on 14 and 15 March so that they could not be targeted.At the time of the MtGox theft, about 750,000 customer bitcoins were stolen as well as close to 100,000 of MtGox’s own bitcoins.That amounts to about 7% of all the bitcoins in existence.

MtGox recently won brief bankruptcy protection in the US as the firm’s case works its way through Japanese courts.

Bitcoin Really Does Represent the Democratization of Money

Bitcoin is commonly regarded as a truly democratic form of money.


Interestingly enough, however, there seem to be various explanations supporting this characterization. Furthermore, at least one of these interpretations have caused some to doubt whether Bitcoin does in fact still represent the democratization of money, or whether it has perhaps become susceptible to less democratic forces throughout the years since its inception. In order to understand why this doubt is understandable yet unjust, it is helpful to recognize which two types of democracy, as distinguished by political theorists such as Cambridge professor John Dunn[1], are often attributed to Bitcoin, and why the most important of the two is still very much intact today.


The first main form of democracy, as set apart by Dunn, is essentially a form of government. Hence, at its core, this type of democracy is ultimately a technical procedure, rather than a political value. This procedure basically encompasses the formation of government through the ritual of elections.


In regard to Bitcoin, this democratic feature is commonly attributed to Satoshi’s proposal for a proof-of-work system, which would function on basis of a “one-CPU-one-vote” mechanism. But as we all know, this democratic feature did not really hold up. Due to the introduction of ASIC-miners and mining-pools, hardly anyone who uses Bitcoin today actually has any vote in this specific procedure at all, while those who do have a major one.


But even though this process of specialization has probably weakened the decentralized nature of the Bitcoin-infrastructure to some degree, the “one-CPU-one-vote” mechanism should hardly be regarded as a fundamental ideal bolstering Bitcoin in the first place. Instead, it primarily reflects one specific function within the protocol: the proof-of-work system. And although that specific function is obviously a fundamental technological innovation, as it helpes to solve the problem of double-spending, it seems to have little to do with ideology.


Moreover, this characterization of “democracy” as “majority vote” is a quite limited interpretation of democracy in the first place. Rather, the ideology of democracy, as developed throughout centuries of work by political philosophers and culminating in both the American and French revolutions of the eighteenth century, consists of various Enlightenment ideals. And this latter version should probably be regarded as the more important of the two types of democracy as distinguished by political theorists such as Dunn. Fortunately, this value is still very present in Bitcoin today.


One of these inherent Enlightenment ideals imbued in both democracy and Bitcoin, is the notion of equality. Fundamentally, this ideal inhabits that all men should enjoy equal rights under the law, and includes issues such as freedom of speech and property rights. This, of course, is very present within the Bitcoin-protocol. As opposed to bank-money, which can be censored at will (as the Wikileaks Banking Blockade has shown the world) it is absolutely not possible to censor payments with Bitcoin, since these payments do not require a middleman, and literally consist of cryptographically protected information – a pure and therefore very equal form of free speech if you will. For similar reasons, arbitrary confiscations of wealth – as seen in Cyprus – are simply out of the question as long as bitcoins are stored securely.


Moreover, the organizational structure behind Bitcoin guarantees an incredibly high level of equality in itself. Fundamentally, no one person has more influence over the protocol than anybody else, nor can anyone bend its rules to his or her own advantage. Not even the inventor, Satoshi Nakamoto, or huge stakeholders, such as the Winklevoss twins, are able to change the Bitcoin-code without reaching a consensus among users. Hence, in stark contrast to the immense power financial lobby-groups have exercised over the monetary policy of many nations, or the apparent Too Big To Fail status of modern-day superbanks, each and every Bitcoin-user is truly equal to the network.


A second inherently important principle underpinning modern Western democracy is the ideal of popular sovereignty. The basic tenet of this principle, which dates back to Thomas Hobbes’ social contract, is the legitimization of the rule of law by the consent of the governed.


And regardless of the legitimacy or desirability of this contract regarding present-day nation-states, central banks run their operations with questionable consent at best. Not only are they purposely removed from the democratic political process (in some cases – like the EU – even quite literally), but merely a tiny fraction of the populace understand what these institutions do in the first place.



Moreover, it stands beyond the slightest glimmer of a doubt that private banks do not manage the money-supply by our consent, at all. And yes, they do manage a tremendous amount of our money supply – much more than most people realize. As opposed to the popular misconception, banks don’t actually lend out central bank issued money; not even indirectly, as the money multiplier model suggests. Instead, they actually create money as credit themselves.[2] Yet, private banks are not accountable to the public at all, as the absolute lack of prosecuted bankers in the wake of the financial crisis has clearly shown. To put it bluntly: our current monetary system makes an absolute mockery out of popular sovereignty.


Bitcoin, on the far opposite side of the spectrum, quite literally exists because of the consent of its users; if they did not consent on the rules of the protocol they would not use it in the first place. And this use, in turn, is what makes this currency itself valuable. After all, Bitcoin would be nothing but source code without its users. Indeed, Bitcoin does not even rule by our consent, it effectively exists by our consent.


By extension, unsatisfied Bitcoin-users can simply elect to withdraw their consent, and perhaps bootstrap a new currency. And this has in fact happened a couple of times already, of course. Unsatisfied with Bitcoin’s mining-algorithm, some have left to (at least partially) support Litecoin. Unsatisfied with Bitcoin’s “waste” of energy, some have left to (at least partially) support Peercoin. And unsatisfied with Bitcoin’s community, some have left to (at least partially) support Dogecoin. Many more might withdraw their consent from Bitcoin in the future, only to transfer it to an altcoin they feel does represent them. They can vote with their feet.


Lastly, the third and arguably most important political value underpinning modern Western democracy is the principle of self-governance. And it’s not much of a stretch to argue that the organizational structure of open source programming is, by far, the best way for common people to organize themselves ever invented. Not only is anybody free to contribute to the rules – the code – of the system, this power does not even need to be transferred to anyone else in order to make it work. With Bitcoin, we now for the first time don’t need to delegate a small group of people to govern the rest, but we can instead transfer this power to universally verifiable open source code, written by and for the people. This is a truly revolutionary form of self-government.


Of course, some of the smartest economists alive today have argued that this is actually not a good thing. According to them, money should not be governed by the people at all. They believe that money should be carefully managed by experts in order stabilize the value, for instance, or to guarantee economic prosperity. According to these economists, if the people are supposed to have any say in this regard, it should be a very indirect influence at most.


But guess what. That’s precisely what some of the smartest political thinkers of previous eras – including the likes of Plato, Montesquieu and Hobbes – argued about democracy itself. All of them expected society to end up in a terrible mess if governmental power wasn’t at least partially claimed by some type of autocratic leadership. Indeed, up until the 1800′s, the term “democracy” was actually a fringe word, only perpetuated by the “insouciant and incorrigible dissidents,” as John Dunn put it: “Those who chose to do so placed themselves far beyond the borders of political life, at the outer fringes of the intellectual lives of virtually all of their contemporaries.”
