Bitcoin 'Glitch' Sparks 23% Flash Crash

While we are used to seeing insta-crashes in our highly-regulated and trustworthy equity markets, the unregulated digital world of Bitcoins suffered another flash-crash last night. According to Ars Technica, the 23% plungefest in the value of the digital currency (the second in a week) was due not to Waddel & Reed, not HFT algos, but 'forking' Cryptographic algos gone wild agreeing on different (legacy) keys as being correct - akin to finding Tungsten in your Gold bars (and hence the drop in the value). This latest glitch is different from the problem that caused Bitcoin prices to briefly crash to zero in June of 2011. In that case, the sell-off was caused by the compromise of the exchange itself, whereas this time the glitch occurred in the core Bitcoin software. Obviously, the incident will be another important test of the cryptocurrency's decentralized governance structure - to say nothing of its reputation among the less technically-capable owners and miners (even though BTC rapidly recovered almost all its losses).

From a high of more than $48 earlier Monday, the value of Bitcoins plummeted to less than $37 around 10 PM Central time on Monday evening, a 23 percent decline. The price has since recovered; one Bitcoin is now worth about $46 - which, one could argue reflects a rapid recoupling with value and confidence (especially given the recent run-up in price) but notably, flash-crashes in equities (as we noted above) never seemed to stop greed-stricken investors piling into them anyway.

Bitcoin rises


Although there is still the possibility of a volatile market, the Bitcoin ecosystem looks more promising than ever.

Bitcoins were valued at $2 by late 2011; a few days ago, values reached the highest ever at $40 [zcopley/Flickr]

About a year ago I wrote an article, published on this site, titled "Understanding Bitcoin". It was an attempt at introducing Bitcoin technology and analysing its social implications. Now Bitcoin markets are trading at record prices of over $40. This increase, along with a series of recent developments, marks a new overall state of affairs for this project. To make better sense - beyond the mere market numbers - of the current state of the Bitcoin economy, it is worth it to make a brief recount of the way Bitcoin has evolved in recent months.

Perhaps the most obvious milestone reached during the last few days is the surpassing of the previous top valuation of U$31.9, achieved by mid-2011. Bitcoin now trades at historically high prices above U$40 per coin. Is the bubble about to burst again? Those who expect a similar crash ought to consider that bitcoins from 2011 are hardly like bitcoins of 2013.

Let's recap. In early 2011, the project started to get attention beyond a very reduced circle of people interested in cryptography. Due to its design (scarcity and floating value), bitcoins do tend to be the object of speculation, and a few online news articles was all it took at the time to drive prices, within a few weeks, from zero to over $30 per coin. However, there was no backing economic substance, no actual economic activity, markets with significant depth or use for the currency. This is why at the slightest sign of trouble - in this case, the hack of one of the exchanges - investors backed away, and the bubble popped. By late 2011, the price had retreated back to $2.

The context in 2013 looks dramatically different to the one during the huge rally-and-crash of 2011. During the last year, the pace of development and adoption by merchants and the NGO sector has steadily accelerated, and the Bitcoin ecosystem in general advanced in many fronts. Recent events in the Bitcoin world announce that a qualitative shift is taking place.

Celebrating protocol

One of the more subtle but profound events that took place in the past few months is a reduction by half in the rate at which bitcoins are produced. It is a characteristic of the Bitcoin protocol that such a change takes place every four years. This transition was baptised by the community of Bitcoin enthusiasts as "Halving Day". It was a significant event at several levels. Symbolically, "Halving Day" is a reminder of the built-in coin scarcity that is at the core of the Bitcoin economy. There was a general sense of excitement in online forums devoted to Bitcoin discussion in the days and hours previous to the "halving". Remarkably, "Halving Day Parties" were held in several cities: nothing less than the social celebration of a software function. A ritual was born from the code.

In economic terms, though, the halving did in fact result in a drastically reduced number of new bitcoins, from 300 to 150 per hour. This severe cutback in production of new coins is likely to have been a factor, among many, in the recent price rises. This is why, in a remarkable demonstration of foresight, Bitcoin miners actually celebrated that their "pay" was being cut in half.

Another reason why the "halving" was a significant event is that, being the first one since Bitcoin's 2009 inception, there was some expectation about how it would unroll, technically. Would the network assimilate the change seamlessly, or would it cause unexpected bugs to emerge, wreaking havok in the whole economy? The technical uneventfulness of this change at the protocol level of the Bitcoin network reaffirmed the confidence in the overall soundness of its design.

Three kings

Large numbers of merchants and organisations have adopted the Bitcoin system since last year. Among the new adopters are three high profile internet companies that have announced implementation of Bitcoin as a payment option: Wordpress, Reddit and Mega. Wordpress, one of the largest global providers of online publishing services, forcefully explained in November the importance of Bitcoin for press freedom worldwide:

PayPal alone blocks access from over 60 countries, and many credit card companies have similar restrictions. Some are blocked for political reasons, some because of higher fraud rates, and some for other financial reasons. Whatever the reason, we don't think an individual blogger from Haiti, Ethiopia, or Kenya should have diminished access to the blogosphere because of payment issues they can't control. Our goal is to enable people, not block them.

Bitcoin is a digital currency that enables instant payments over the internet. Unlike credit cards and PayPal, Bitcoin has no central authority and no way to lock entire countries out of the network. Merchants who accept Bitcoin payments can do business with anyone.

Similarly, two other big internet players, with millions of users, have made the Bitcoin nod in recent weeks. Reddit, an epicentre of internet culture, as well as rebellious Kim Dot Com's recently launched data storage service, Mega, released corresponding announcements in recent weeks. The internetist (if I may invent this term) nature of Wordpress, Reddit and Mega has led to exposing millions of new users to Bitcoin. Their adoption spread far and apart seeds for a new "generation" of Bitcoin users, advocates, and developers.

Metal gear

The hardware side of the Bitcoin system has also shown new developments, especially in the field of Bitcoin mining. Originally, it was possible to "mine" bitcoins with a consumer PC, but as more people joined to compete for the 300 new bitcoins being awarded every hour, increasingly powerful computers were required to earn coins using this method. "Mining Rigs", computers built from off-the-shelf parts for the sole purpose of 24-hour bitcoin mining, quickly appeared, some of them filling large rooms with such equipment. The protocol not only generated ritual social celebrations like the "Halving Parties" described above, it also started affecting hardware. Because of the protocol, mining computers started physically growing, spreading like moss, beyond their original boxes, even entering a new kind of relationship with architecture. Code - in this case Bitcoin protocol - changed metal.


Approximately one year ago, a further development in mining was announced: a new kind of computer chip specifically designed to optimise the execution of the instructions required by the Bitcoin protocol for efficient mining. The first such machines (known as ASICs) were finally delivered in February, signalling the beginning of a new era of professional bitcoin mining and the increase, by an order of magnitude, in the robustness of Bitcoin infrastructure in terms of computing power.

Bitcoin-logic ventures

During the course of 2012 and early 2013, the first significant investments of venture capital in Bitcoin-oriented startups started to pop up. BitPay.com and Coinbase.com, two Bitcoin payments processor startups, respectively secured U$500,000 and U$600,000 investments. That has allowed them to set up infrastructure to compete with PayPal, and among each other. CoinLab.com, a company initially created to blend online computer gaming with bitcoin mining, secured a similar amount. The long term significance of these investments has been highlighted by Vitalik Buterin from Bitcoin Magazine:

Late 2012 has been a pivotal period for Bitcoin. Although the main indicator of the "financial" size of Bitcoin, the Bitcoin price, the key difference between Bitcoin's rise in price now and its bubble then is that in 2011 the Bitcoin markets' trade volume was backed almost entirely by speculation. (...) investors interested in Bitcoin are starting to look beyond the Bitcoin markets, and are instead increasingly focusing their eyes on the underlying Bitcoin economy - substituting mere speculation with increasing investment into the businesses that make both Bitcoin adoption and the Bitcoin price go up in the first place.

In a move that amounts to Bitcoin's exit out of the legal grey area in Europe, a company called Bitcoin-Central announced in December integration of Bitcoin with French banking infrastructure:

Bitcoin Central account will have all of the core features of a standard bank account in Europe. Each account will have its own international bank account number (IBAN) with which anyone will be able to send money to that account via bank wire. On the withdrawal side, Bitcoin Central will soon issue debit cards similar to those now in the works by BitInstant that would automatically convert the holder's BTC balance to euros on the fly. And, finally, the euro balance of a Bitcoin Central account will be federally insured up to $100,000 by the French "Garantie des depôts."

Similarly, two US Bitcoin companies, Coinbase and CoinLab, now offer traditional bank account integration. In a move that has been described as "a key step towards going mainstream", CoinLab recently announced a partnership with Silicon Valley Bank.

New Bitcoin businesses, merchants and service providers pop up every day. There is intense experimentation with business models that are only possible because they follow Bitcoin logic.

For instance, Bitcoin-Proxy merchants. These services offer a way to bridge people who want to spend their bitcoins and the merchants who do not yet have bitcoins as a payment option. Bitcoin-proxies have already been set up for pizza, hotel bookings, and even the whole catalog of large retailers like Amazon, Ebay or Target.

In general, the field of Bitcoin payments processing is seeing intense activity, with several startups like BitPay, Paysius, BIPS and Coinbase competing for new costumers. Sector leader BitPay has reported having as much as 3,000 merchants.

Likewise, there are numbers of new Bitcoin-based ways to gamble. Some examples like Bitcoin Gem, Bitcoin Vegas (a Bitcoin casino set up inside the virtual world of the video game Minecraft), and Satoshi Dice show how once Bitcoin logic is applied to an economic activity, new and unexpected forms will emerge. This kind of Bitcoin experimentation intensifies as the Bitcoin economy strengthens, and is likely to produce diverse previously impossible business ideas that will further drive Bitcoin adoption.
The Stream
The currency of protest


Virtuous spirals

High Bitcoin valuation means an empowered class of Bitcoin entrepreneurs. People who own Bitcoin in large numbers are increasingly in possession of no-strings-attached capital. They can, and they do, use this capital to implement further functionality for Bitcoin. In this way, many Bitcoin holders can increasingly afford to hire web services, programmers, designers and (crucially) top legal advice. All these activities add value to Bitcoin as a whole, resulting in yet greater empowerment for Bitcoin entrepreneurs. This virtuous spiral has actually been taking place since Bitcoin's beginnings, and the effect is an order of magnitude more powerful at today's Bitcoin price of about $40 rather than last year's $4.

The distributed nature of Bitcoin's economy means that right now there are thousands of enthusiastic Bitcoiners that can afford to self-fund their experiments and their visions for the next wave of Bitcoin applications and growth. Many will fail, but others will succeed; in the process of becoming of this global collective intelligence entity, every single Bitcoin holder benefits from the work of the rest. Enhanced Bitcoin usability means greater demand and a higher price. This upwards cycle is embedded in the design on the Bitcoin network.

Community foundations

The processes of maturation of a Bitcoin community spread through several countries, although mainly concentrated in Europe and the US. What started with a handful of people in a specialised online cryptography forum, sharing opinions about code and security, now spans thousands of active participants across diverse online platforms like the bitcointalk forums, the r/Bitcoin subreddit, and a number of IRC channels, of which #bitcoin-otc is perhaps the most active. In 2012, the community organised and launched the Bitcoin Foundation focused on development and advocacy efforts.

The community has also been active in creating physical meeting spaces and events, including meetups in most major cities around the world, and a series major of conferences. At least two of these large events have been planned so far for 2013. The first event, "Bitcoin 2013: The Future of Payments", is organised by the Bitcoin Foundation and will take place in San Jose, California in May. The second, unSYSTEM, is organised by activist Amir Taaki and will take place in Vienna, Austria, in November. Put together, these two events bring together all of the most influential names in the development of Bitcoin, and many of the most active actors involved in free software, freedom of the press, and online liberties.

This article does not pretend to predict the behaviour of the markets. Especially, Bitcoin is impossible to predict due to the existence of accounts that concentrate significant amounts of bitcoins. Because any actor might decide to make a big sale (or a big buy) at any point, it is perfectly possible to see extremely wild swings in market prices in the near future. However Bitcoin 2013 is certainly a much more robust animal than its 2011 version, and its future looks more promising now than ever before. Step by step, Bitcoin rises.

In Spain, The Bitcoin Run Has Started

Something extreme is happening in Europe. Since Sunday, Bloomberg Businessweek reports a trio of Bitcoin apps have soared up Spain's download charts, coinciding with news that cash-strapped Cyprus was planning to raid domestic savings accounts to pay off a $13 billion bailout tab. “This is an entirely predictable and rational outcome for what’s happening in Cyprus,” says ConvergEx's Nick Colas. "If you want to get a good sense of the stress European savers are feeling, just watch Bitcoin prices."

The value of the virtual currency has soared almost 30 percent in the last two days. "One hundred percent of that is due to Cyprus," says Colas. "It means the Europeans are getting involved." As German economist Peter Bofinger warned in an interview with Spiegel Online: "European citizens must now fear for their money."

The same apps download data, however, showed that Italians aren’t ready to abandon commercial banking, remarkable as many Italians still recall that black day in 1992 when they woke up to a levy on their savings accounts to prop up the nation’s teetering finances.



The EUR price for a Bitcoin has jumped from around EUR37 to over EUR50 in the last two days as reality hits... and look at the volume...

Canadian house first on sale for Bitcoin currency


A Canadian man is selling his house in exchange for Bitcoins – the world’s alternative decentralized digital currency that is gaining popularity with more and more people, trying to keep their deposits safe as they lose trust in real currency.

Twenty-two-year-old Taylor More is the first to list his two-bedroom bungalow in Alberta on the website For Sale By Owner in exchange for the hard-to-trace digital Bitcoins - 5,362 of them (US$395,000).

“My home is being traded for Bitcoins!” reads More's listing. “Properties like this rarely come on the market and this one's priced to sell in one of the most sought-after recreation areas of the Rockies.”

The current exchange rate of one Bitcoin is US$73.

“I have a few projects that I am working on that involve Bitcoin and they happen to be a pretty hard thing to get your hands on right now if you want to get them in large quantities,” More told CBC. “So I figure the best way to get them is to try to sell our property.”

Bitcoin is an experimental, decentralized digital currency first introduced in 2009, which allows instant payments to anyone, anywhere in the world. Bitcoins do not physically exist and are not issued by a central bank.

“Because it has no central authority no one can freeze accounts. So people are seeing the beauty of it, especially considering what is going on in Cyprus with everyone’s bank accounts being frozen. This is a way to keep your savings safe,” argues More.

The currency has been growing in popularity because of its privacy and the ease of peer-to-peer payments. Bloomberg valued the “alternative world currency” at over US$600 million.

“You basically have an e-wallet and every wallet has its own ID number and that is how you are recognized in a Bitcoin world,”
added More.

There are various services that accept Bitcoin as payment, including an online Bitcoin store, which sells everything from electronics to beauty products and sports goods. Another Pizzaforcoins.com website accepts food orders in exchange for the online currency. An office space rental company in Toronto, Canada, allows people to rent rooms using Bitcoins. There are some hotels that also accept the digital money as payment.

There was even a first dollar-converting Bitcoin ATM developed in early 2013.

More has not received any offers on his house so far.

Het klinkt mooi dat bitcion geburen

maar geld blijft geld
slimme mensen(met een beetje minder empathisch vermogen) weten er wel weer misbruik van te maken

hier eens wat negatief nieuws
Bitcoin Report Volume 8 - (FLASHCRASH)
[video][/video]
"Mensen zullen persoonlijke hardware en software vertrouwen voor het verwerken van financiële transacties over het internet en in winkels. Cash en betaalpassen zullen bij de meeste transacties in geavanceerde landen verdwenen zijn", aldus de stelling die de onderzoekers de experts voorlegden. Deze experts vinden dat mobiel geld de volgende logische stap in de evolutie in consumenten financiën is. Mobiele betalingen zouden namelijk meer veiligheid bieden dan cash of fysieke betaalpassen.
bron: https://www.security.nl/artikel/41170/% ... 20%22.html


B) volgns mij is het een opwarmer om ons klaar te maken voor het einde van contant geld
heel erg slim opgezet ver vooruitgedacht plan

jaja bankiers kunnen ook op langer termijn denken :woohoo:

gemak dient de mens:whistle:
Ik zit er wel op te wachten hoor... Het is nl. veel gemakkelijker: je hoeft dan niet meer een portemonnee bij je te hebben met contant geld, allerlei pinpassen en creditcards. Je hoeft dan alleen nog maar je smartphone bij je te hebben en die effe langs de betalingsterminal of iets dergelijks halen! Hartstikke gemakkelijk toch! Niet meer de beurs hoeven trekken en contant geld te moeten afpassen. Niet meer het goede pasje moeten zoeken, in de sleuf moeten steken en de pincode moeten intikken. Wat een gedoe is dat eigenlijk!
Cash gaat in de ban
De Consumentenbond zegt in het AD dat 'cash in de ban gaat'. Ook Detailhandel Nederland zegt dat contant betalen in de nabije toekomst verleden tijd zal zijn. "Het is een sneeuwbal die steeds harder gaat rollen.
http://www.dedetailhandel.nl/nieuwsExte ... winkels%27


B)
de verdwijntruc van het CASH geld!

Men zal claimen dat het drukken en persen van CASH teveel geld kost.

Men zal ook de oplopende kosten aanhalen verbonden aan de beveiliging van geldtransporten die steeds vaker zullen worden overvallen.

Om van de almaar toenemende valsemunterij maar niet te spreken.

Er is eigenlijk al veel verandert in het bankwezen tov vroeger.

De gratis bankpasjes zijn vervangen door betaalpasjes, wat ronduit schandalig is omdat je hebt zo’n ding nodig hebt als je aan je eigen geld wilt komen!

Het aantal gratis girobetaalkaarten is uitgedund en je moet er tegenwoordig voor betalen.

De klantvriendelijk en service van deze financiële “dienstverleners” is al een tijdje in het geding doordat filialen in dorpen zijn afgestoten en men er steeds meer op aandringt via het internet te bankieren.

Als gevolg van deze “reorganisaties” is veel bankpersoneel ontslagen.

De balies in de banken zijn onpersoonlijk geworden, alles moet tegenwoordig staand gebeuren, alsof men je snel weer de deur uit wil werken, een enkele bank (en dan spreek ik van buitenlandse banken) biedt je tegenwoordig nog een stoel aan en een kopje koffie om de vriendschappelijke relatie tussen bank en klant (van vroeger) nog eens te benadrukken.

De bereikbaarheid van de banken is teruggebracht naar wat hoofdfilialen in de grote steden, een website die regelmatig plat ligt en een duur 0900 “servicenummer” van 1,45 euro!

Met ouderen wordt ook steeds minder rekening gehouden.

Rente krijg je ook al haast niet meer op je spaartegoed (voor zover je die nog hebt).

Nog even en men laat je betalen voor het op laten slaan van je “vermogen” op de bank!

Ook wil ik nog even op de Rfid- Verichip terugkomen.

Deze chips zullen waarschijnlijk nog eens versneld ingevoerd worden, waarbij men zal claimen dat het de veiligste manier is om te betalen, als zijnde de veiligste manier van identificatie (het herkennen van de eigenaar van de rekening)!

Men zal daarbij claimen dat u geen zwaar CASHgeld meer bij u hoeft te sjouwen.

Men zal hierbij ook claimen dat u veiliger over straat kunt lopen omdat, doordat u geen CASH geld meer bij u draagt, en u dus geen slachtoffer meer wordt van overvallers omdat er bij u niets te halen zou zijn.

Dit virtuele geld zal de kapitalist super vermogend maken, in geval deze het nog niet mocht zijn.

De (Staats)banken kunnen nu immers net zoveel virtueel geld creëren als zij denken nodig te hebben, zonder bang te hoeven zijn dat iemand haar/zijn vermogen zou incasseren, omdat er tegen die tijd geen CASH geld meer bestaat.

Niemand zal het opmerken als de komma bij bepaalde transacties een plaatsje is opgeschoven, en mocht het toch opvallen dan beroept men zich op een menselijke of computerfout.

Overigens:
Vijf vragen over Bitcoins
Toegevoegd: maandag 1 apr 2013, 18:41
Update: maandag 1 apr 2013, 18:43


Wat zijn Bitcoins?

Bitcoin is een virtuele munteenheid, die je met echt geld kunt kopen. Dat klinkt bijzonder, maar dat valt wel mee. Als je een cadeaubon koopt, of munten op de kermis, doe je eigenlijk hetzelfde. Het belangrijkste verschil zit hem in wie de munten uitgeeft. Dat is niet de winkelier of de kermisbaas. Het is zelfs niet de bank of een overheid. Het zijn de deelnemers aan Bitcoins zelf die de munt beheren.

Het grote voordeel is dat de munt uitgewisseld kan worden tussen deelnemers, zonder dat er iemand tussen zit. En in een tijd waarin mensen steeds minder vertrouwen hebben in banken en overheden, lijkt Bitcoin voor sommigen een aantrekkelijk alternatief.

Wie is de baas of de oprichter van Bitcoin?

De Japanse programmeur Satoshi Nakamoto heeft Bitcoin bedacht, maar wie hij is en of hij wel echt bestaat is onduidelijk. Hij bedacht dat niet een bank, maar de computers van alle deelnemers samen het systeem beheren en transacties goedkeuren. Op basis van zijn ideeën zijn programmeurs wereldwijd aan de slag gegaan en hebben ze de programmatuur gebouwd die dit mogelijk maakt. Die is open-source dus iedereen kan er aan bijdragen.

Het systeem maakt gebruik van zware cryptografie om te voorkomen dat munten bijmaken een kwestie van copy-paste is. En: er is maar een maximaal aantal Bitcoins dat kan worden uitgegeven. Op is op. En dus is schaarste inherent aan het systeem. Sommige analisten, onder anderen die van de Europese Centrale Bank, vergelijken Bitcoins daarom wel eens met goud.

Waar komen de munten dan vandaan?

De munten worden niet geslagen, maar berekend. Dit noemen ze 'mining'. Het algoritme dat Bitcoin gebruikt is zo gemaakt dat naarmate er meer Bitcoins komen, er steeds meer computerkracht nodig is om ze te berekenen. Wie meedoet aan het berekenen krijgt als dank zelf Bitcoins. Maar inmiddels is de vraag zo groot en de moeilijkheidsgraad zo hoog, dat het alleen nog loont om Bitcoins te minen met speciale computers. Mensen bouwen die zelf en er komen steeds meer bedrijven waar je die kan kopen.

Hoe kom ik aan Bitcoin?

Er zijn verschillende marktplaatsen waar je Bitcoins kunt kopen in ruil voor euro's of dollars. De bekendste is Mt. Gox in Amerika. Er is inmiddels een meer dan levendige handel in Bitcoins ontstaan. Er is zelfs een wachtlijst voor wie wil deelnemen. In Nederland kan je bij Bitbank of Bitonic via iDEAL meteen Bitcoins kopen. De koers is een stuk minder gunstig dan in Amerika. Bitcoins sla je op in een wallet, een digitale portemonnee. Die kan op je eigen computer staan, of op internet worden beheerd. Meer lees je er over bij Bitcoin.org.

Wat is het risico?

De koers van Bitcoin schommelt enorm. Er is geen enkele bescherming tegen een digitale beurscrash. Volgens critici is er op dit moment, opnieuw naar analogie met goud, een echte goudkoorts aan de gang. Die kan volgens sommigen alleen maar eindigen in een digitale crash.

Verder beginnen steeds meer overheden zich af te vragen wat ze hiermee aan moeten. Meer regulering ligt op de loer. En tot slot natuurlijk hackers. Die hebben in het verleden al tonnen aan Bitcoins gestolen.

Beyond Nakamoto, several other people are key to the ongoing development of the Bitcoin system. Many of these people work with Bitcoin strictly as volunteers. Many of those volunteers probably own quite a few bitcoins, which means it’s in their best interest to see the Bitcoin system grow and succeed. Others have made a profession out of creating services that focus on the Bitcoin system. The following list includes both types of Bitcoin supporters:

Gavin Andresen. He helps maintain the original Bitcoin client software as a core developer.

Matt Corallo. He developed part of the Bitcoin client software.

Hal Finney. He is an early contributor to Bitcoin, as well as the founder of PGP.

Jeff Garzik. He is one of the core developers of the Bitcoin software, and he’s a founder of Bitcoin Watch.

Martti Malmi. He is an administrator on the Bitcoin Forum, and he is the operator for Bitcoin.org.

Michael Marquardt. He is the creator of the Bitcoin Talk forum.

Jed McCaleb. He is the original developer of the Mt. Gox Web site.

Nils Schneider. He owns both BitcoinWatch and BitcoinCharts, while serving as a core developer of the software.

Patrick Strateman. He created the Python Bitcoin implementation process.

Wladimir J. van der Laan. He helps maintain the Bitcoin client software as a core developer.

Pieter Wuille. He is a core developer of the Bitcoin software, and he maintains Bitcoin network graphs.
