Volatility, Deflation and Manipulation: A Response to Bitcoin's Critics

Note: Excellent audio version is available on SoundCloud.

Bitcoin has its share of critics and skeptics, and opposition to the emerging technology – especially among the intelligentsia – shows no sign of abating.

Notable commentators on the topic range from author Jeffrey Robinson to finance blogger Karl Denninger, Boston University professor Mark Williams, rabid Keynesian Paul Krugman, Austrian economist Gary North and FT Alphaville's Izabella Kaminska.

Generously, I'm assuming that the pundits listed above have a thorough and accurate understanding of the bitcoin protocol that facilitates its native token's dual role of currency and commodity.

Typically, the arguments put forth by an elite group of critics like this could be easily attributed to a lack of economic credentials or real-world experience in sophisticated financial markets. But that is simply not the case here – which makes it all the more puzzling to comprehend. Since the various critiques fall short on any convincing economic analysis, I suppose one could put it down to mere philosophical differences on the origin and nature of money.

With the resilience of distributed peer-to-peer networks amplified by powerful public key cryptography, we are all in new territory now; the world stands on the precipice of a fundamental realignment in the transfer of value. At its root, bitcoin is a value transfer protocol. We may voluntarily choose to utilize it or not. Most importantly, there is no coercion imposed through legal tender laws.

Value is subjective

Perhaps most disturbing to the bitcoin critics is the fundamental myth that bitcoin exposes – the myth that the State confers value on money and that we need 'kings' to coin our money.

We are constantly reminded by the critics that money can only be a legal creature of the State and that it is the "civil society system which puts the value into currency". Expounding on the thesis advanced by German economist Georg Friedrich Knapp in The State Theory of Money (1924), an exposé advocating the Chartalist approach to monetary theory claiming that money must have no intrinsic value and strictly be used as tokens issued by the government, these modern-day chartalists promote the notion that only governments and sovereign issuers have the ability to confer legitimacy to money.

A belief in central banking is also a belief in the central planning of an economy. Additionally, it represents central planning of the highest order, because it interferes with the market's price discovery process for money – the rate of interest.

As the antithesis of central planning in money, bitcoin gradually achieves more and more market-based legitimacy. Institutional and government legitimacy are not required for bitcoin to serve as store of value, medium of exchange and unit of account.

Kaminska's first piece on bitcoin in early 2013 highlighted a fairly good interaction between Chris Cook and an Austrian economist on the intrinsic value debate. Here's more on subjective and intrinsic value with Willem Buiter, chief economist at Citi.

Volatility is a red herring

But wait, isn't all this volatility damaging bitcoin and its reliability as a store of value and medium of exchange?

As bitcoin grows and matures, multi-jurisdictional exchanges will emerge which also include specialized derivatives products for hedging risk and this will have the effect of increasing market capitalization and smoothing out price volatility. Bitcoin swaps are already being conducted over swap execution facilities.

Although important, the speculative volatility is actually a sideshow to the main event of bitcoin establishing a footing in the financial world. Even at a mere six years old, bitcoin exhibits no more volatility than the luminary Swiss franc or North Sea Brent crude oil, with the latter losing more than 50% of its value in about six months.

Fear not deflation

But what about the hoarding of bitcoin? Isn't that bad for its use as money?

I prefer to call it savings and maybe it's time to unlearn all those lessons taught in school. Savings and deflation are not bad for an economy. As Jörg Guido Hülsmann once said: "We should not be afraid of deflation. We should love it as much as our liberties."

Contrary to the central banking and political class insistence that deflation must be prevented at all costs, an economy with a monetary unit that increases in value over time provides significant economic benefits such as near-zero interest rates and increasing demand through lower prices.

Ultimately, the market will reach an equilibrium between investment and savings because in the absence of an equilibrium the benefits of a savings-only strategy would evaporate. Proper economic growth through sound investments will lead to a productivity-driven deflation.

Ironically, it's the store of value function for bitcoin which enables and reinforces its use as a medium of exchange. According to Daniel Krawisz of the Satoshi Nakamoto Institute, hoarders give bitcoin value and he states that "the initial price of bitcoin was caused by people who wanted to hold it, not people who wanted to spend it. Furthermore, each subsequent step in bitcoin’s advance must begin with more holders, not more spenders."

No naked shorts, so far

I am continually amazed by those who shout "market manipulation" yet fail to see the very blatant manipulation they abhor present in the naked short selling of precious metals and in the Plunge Protection Team. We all know the world's most important trading desk sits on the 9th floor of 33 Liberty Street.

Kaminska writes: "Bitcoin markets are a hotbed for unscrupulous market practices. Everything from HFT, front-running, rebating, preferential order flow, poor margining, naked shorting, and now the truly popular one – active 'collusion' by big players. It’s all there."

In reading this, you would be forgiven in thinking that Kaminska might also be referring to highly-regulated markets populated by the likes of MF Global and the interest rate rigging cartel of RBS, Citigroup and JP Morgan. She is not. Certainly Kaminska doesn't condone that type of market activity, but that's not really the point.

The point is that we have a brand new marketplace, for a digital bearer instrument no less, germinating in parallel to the entrenched incumbents and along the way battling the retail and wholesale payments oligarchy as well as the vested interests of legal tender threatening bans. Of course, the bitcoin exchange markets experience illiquidity, lack of market depth, and a few bad actors willing to exploit such conditions. They are in the vanguard of cryptographic security architecture for dynamically-connected bearer wallets.

Fraud on any level, whether State-sponsored or from malicious principals, has no excuse and should not be tolerated. The solution is not to ensconce the new exchanges in the straight-jacket of the perceived level playing field with too-big-to-fail benefits and socialized losses, but to encourage multiple competitive exchanges across multiple jurisdictions. We wouldn't have the COMEX tail wagging the spot market dog if we had robust precious metals derivatives markets on every continent.

With bitcoin and exchanges, it's all about jurisdictional arbitrage.

Should we really believe that the two young founders of Bitstamp match the antics of Jon Corzine? After all, episodes like Bitstamp are not due to an orchestrated crisis of liquidity.

But who will protect the people?

The European Banking Authority published their report on virtual currencies complete with a risk drivers chart of 70 bitcoin risks, which was promptly hailed by the FT Bitcoinmania crowd.

For a sane and thoughtful response, we turn to Ken Tindell, who believes that the "EBA’s considered opinion is that European financial institutions should shun bitcoin like a dead skunk and go nowhere near it until the 'scheme operators' are persuaded to change bitcoin to be managed by a wise and omniscient regulator." He concludes that the EBA doesn't really understand bitcoin and they exaggerate the risks to support a mandate which deters financial innovation unless it fits into their limited construct.

In the United States, the Consumer Financial Protection Bureau did the same thing with the publishing of its advisory warning to consumers about the risks of virtual currencies.

To better assist consumers, I described some of bitcoin's superior attributes in the area of financial protection, because when the words 'financial protection' are in your agency's official name, it appears disingenuous to omit features from what may be one of the world's most protective financial instruments ever designed.

In no particular order, bitcoin provides protection from counterfeit bank notes, protection from financial surveillance, protection from identity theft, protection from physical loss of assets, protection from cross-border restrictions and excessive fees, protection from payments blockades, protection from government-sponsored inflation, and protection from confiscation. Can your currency do all that?

Furthermore, without a central bank and without taxpayer-funded deposit insurance, it is somewhat comforting to know that bitcoin's lender of last resort is the same as the lender of last resort for gold – those silly believers of subjective value.

In the province of financial journalism, bitcoin unmasks the Statists.

Bitcoin Needs an Aggressive Legal Defense

By Jon Matonis
CoinDesk
Monday, November 24, 2014

http://www.coindesk.com/bitcoin-needs-aggressive-legal-defense/

Across the board, bitcoin requires forceful and aggressive legal defense, not complicity with governments in crafting policy and regulations. It's going to get a lot rougher for bitcoin in the months and years ahead. We have to be prepared.

As Rick Falkvinge, author of Swarmwise, states, "The copyright monopoly war wasn't the war, it was the tutorial mission. The Internet generation is using technology to assert its values and its place in society, the old industrial generation is pushing back hard against irrelevance. Things are about to get much worse."

It is a superb analogy. Legal tender is essentially an unearned copyright privilege over the production of money. It is unlikely to be easily disrupted.

Only the naive can delude themselves into thinking that governments will embrace bitcoin in the name of monetary innovation or a modern techno-transition to the 'Internet of Things'. What government permits with one hand, it restricts and strangles with the other. Therefore, any regulatory gains by the bitcoin community are elusive, because they are designed to appease, while government enforcement actions reveal a contradictory agenda.

The real battle lies elsewhere, beyond the public policy debate.

There hasn't been a judicial test case for bitcoin legal issues yet, primarily because at least two candidates that got sufficiently close to a legal challenge elected to comply with authorities rather than risk the uncertain outcome of a test case.

On November 27, 2013, Mike Caldwell of Casascius Coins suspended the operations that made his branded coins the global standard for physical bitcoin rather than adopt a legal stand. While writing Bitcoin Ideology and Tale of Casascius Coins, I had the opportunity to consult with Caldwell and his attorney personally, so I fully understand their decision.

Also more recently, Las Vegas-based Robocoin capitulated to FinCEN pressure and started requiring all ATM operators to obtain customer information in an effort to comply with know-your-customer (KYC) regulations.

In my opinion, this was a missed opportunity to determine the legal categorization of a bitcoin vending machine and to set solid precedent. What if bitcoin vending machines dispensed only candy bars with 'paper wallet' wrappers or soda cans with removable wallet decals?

Recommended bitcoin legal areas for mounting a strong, concerted defense include: mandatory key disclosure, restrictions on freedom of transaction, attacks on bitcoin fungibility via blacklisting and whitelisting, and denying the principle of code as protected speech.

Mandatory key disclosure

Key disclosure laws may become the single most important government tool in asset seizures and the war on money laundering. These refer to the ability of the government to demand that you surrender your private encryption keys that decrypt your data when charged with a criminal offense. If your data is currency, such as access control to various amounts of bitcoin on the blockchain, then you have surrendered your financial transaction history and potentially the value itself.

Jail time for refusing to comply with mandatory key disclosure hasn’t occurred in the US yet. But, it’s already happening in jurisdictions such as the UK, where a 33-year-old man was incarcerated for refusing to turn over his decryption keys and a youth was jailed for not disclosing a 50-character encryption password to authorities.

Key disclosure will become increasingly important in civil assets seizures, since Kim Dotcom's pretrial legal funds would have been safe with bitcoin.

It is very likely that a significant key disclosure case will make it to the US Supreme Court, where it is far from certain that the Fifth Amendment privilege, as it relates to a refusal to decrypt bitcoin assets, will be universally upheld.

Freedom of transaction

In support of an individual's freedom to transact without requiring a license to operate a 'money services business', the Bitcoin Foundation filed an amicus brief in a Florida state criminal case tied to alleged bitcoin transactions. In that case, an individual faces one count of being an unauthorized money transmitter under state law and two counts of money laundering.

The charges against the individual were filed in March 2014 and it is the first known state criminal case involving the alleged buying and selling of bitcoin. Another defendant was arrested at the same time based on similar alleged conduct and has been separately charged. This Florida case has received wide-spread media attention, such as from Bloomberg.

The foundation’s amicus brief supports the individual defendant’s motion to dismiss the count charging him with being an unauthorized money transmitter based on the core position that state prosecutors are improperly applying Florida statutes regulating 'money services businesses' to individuals conducting peer-to-peer sales of bitcoin.

This case is a big deal because it specifically targets high-dollar-value transactions and prosecutions like these could shut down one of the last remaining avenues for purchasing bitcoin anonymously.

Denying an individual's freedom to transact violates freedom of choice in currency, which is similar to an outright ban on bitcoin. In a ban, government authorities prohibit pricing or use of a currency other than the nation's 'official' currency, as witnessed in Bolivia, Ecuador, Kyrgyzstan, Bangladesh and Russia.

The ban in Bangladesh extended to even informing or educating others about bitcoin, prompting the nonprofit and educational Bitcoin Foundation Bangladesh to suspend operations temporarily.
In a slightly more positive development this month, Russia’s Ministry of Finance reduced potential fines facing both individual and institutional bitcoin users who create, issue or promote digital currencies.

The draft bill, which still seeks to outlaw the use of 'money surrogates' like bitcoin, decreases penalties for individuals to 50,000 rubles ($1,050) from 60,000 ($1,314). Legal entities would now face a maximum fine of 500,000 rubles ($10,781) for this action, down from 1m rubles ($21,563).

Fungibility

Fungibility refers to the concept that every unit or subunit remains equivalent and identical to any other unit or subunit. It is the property of a good or commodity whose individual units are capable of mutual substitution.

Fungibility is a complex issue, because it can be described in economic terms, cryptographic terms and policy-based terms.

Hashcash inventor Adam Back states that cryptographic fungibility is stronger than policy-based fungibility. Cryptocurrency expert Jonathan Levin replies that there is actually no cryptographic fungibility in bitcoin and that the best suggestion of this is simultaneous creation and destruction. Zooko Wilcox-O'Hearn, a computer security specialist, asserts that policy-based fungibility ends at the jurisdictional border.

While bitcoin public addresses do have a traceable history, the sub-unit components that make up a single bitcoin transaction do not have unique identifiers, such as the serial numbers on paper bank notes. Since individual transactions are able to be broken apart, each component unit can only be traced realistically to its creating miner. This complicates reliable ownership and thus provides an element of  plausible deniability for the entire infrastructure.

I maintain that the US Marshal Service's first, and now second sale, of seized bitcoin demonstrates current fungibility at least in the US jurisdiction. Just as the government doesn't spend confiscated dollars at a discount, they don't sell 'tainted' bitcoin at a discount and, furthermore, none of the offered coins are blacklisted or whitelisted. A commercial precedent has been set.

Varying tax treatments for bitcoin may have an impact on bitcoin fungibility within certain geographic areas, however. Also, read what a landmark legal case from mid-1700s Scotland tells us about monetary fungibility.

As governments attempt to steer bitcoin deployment to small and microtransactions and wholesale payment networks become politicized, the issue of international fungibility looms large, because large cross-border and permission-less value transfers may become bitcoin's sweet spot. Now, that's a sweet spot for a strong legal defense too.

Code as speech

Transmitting a bitcoin message to the network blockchain is the same as sending an encrypted, private email message and, as such, is protected under the First Amendment to the US Constitution. This important principle extends to both the development and usage of the code.

For the last 24 years, the Electronic Frontier Foundation (EFF) has been at the forefront of defending civil liberties in the digital age, championing user privacy and free expression. Activism director Rainey Reitman's brilliant editorial opposing New York's proposed 'BitLicense' scheme is a powerful declaration of privacy rights.

"Digital currencies such as bitcoin strengthen privacy and are resistant to censorship. We should consider this a feature, not a bug," Reitman said in a statement.

The EFF also defended MIT student bitcoin developers in a New Jersey court to oppose a subpoena issued over their prize-winning bitcoin mining program. The program known as Tidbit was designed to serve as an alternative to viewing online advertising by allowing website users to help mine bitcoins for the site they're visiting instead.

In a move that could strengthen bitcoin-related privacy, Senator Rand Paul of Kentucky recently introduced a bill to extend Fourth Amendment protections to include electronic communications.

Also, anticipating potential Fourth Amendment-related challenges, the Bitcoin Foundation's global policy counsel Jim Harper compared New York's BitLicense regulation to an inspection of an entrepreneur's garage:
"The comprehensive financial surveillance that the 'BitLicense' proposal requires at proposed sections 200.12(a)(1) and 200.15 is unwarranted, and the Department has put forth no evidence or argument that it is calibrated to cost-effectively achieve any public interest goal. Requiring businesses to maintain detailed surveillance of their customers anticipating later law enforcement seizure is itself a constructive seizure, which is unconstitutional under a proper interpretation of the Fourth Amendment to the US Constitution."
Now, if India had Fourth Amendment protections, egregious office raids, such as the ones carried out last December against two bitcoin exchanges, could have been effectively challenged. India may need to seek out alternative avenues for defense.

The way forward

I am hopeful that with criminal defense and trial attorney Brian Klein more closely associated with the Bitcoin Foundation, other defense attorneys will be encouraged to engage with the bitcoin community, domestically and internationally.

Taking a principled stand in Bangladesh, for instance, will send a strong message to the entire world. When it comes to impact litigation, the EFF cannot do it all. We should view this as an opportunity for bitcoin advocacy groups to grow a backbone.

Why Bitcoin Needs an ISO-Certified Currency Code

By Jon Matonis
CoinDesk
Tuesday, October 21, 2014

http://www.coindesk.com/bitcoin-needs-iso-certified-currency-code/

A formal ISO currency code will spur global mainstream adoption of bitcoin more than any other single action.

When a new currency code becomes adopted by the independent and nonpolitical International Organization for Standardization (ISO), it immediately enters the database tables upon which Visa, MasterCard, PayPal, SWIFT and other clearing networks rely.

ISO 4217 is a standard published by the ISO, which delineates currency designators, country codes (alpha and numeric) and references to minor units in three separate tables.

Now, a distributed currency having an identifiable code in a centralized database may not seem like much of an accomplishment.

However, when we consider what this means for integration into existing networks, trading systems and software accounting systems, it becomes much more significant. All the more so when we consider that a code prefix of 'X' denotes a non-national affiliation or a monetary metal such as gold or silver.

Instantly, bitcoin as XBT will be available as a selectable clearing and settlement unit for any business that chooses to offer and implement bitcoin. Of course, designing and managing the necessary settlement and hedging mechanisms will be a different matter altogether. Certain clearing networks may effectively become bitcoin exchanges.

With the three-character code having been in informal usage since early 2013, a formal application for XBT is nearing completion by the Financial Standards Working Group within the Bitcoin Foundation. This effort has its origins in a petition submitted by Emelyne Weiss that circulated on Change.org, the world's platform for change. The petition closed with 836 supporters.

Since the decentralized bitcoin has a peer-to-peer block chain rather than an 'official' currency manager, a central bank or an existing institution such as SWIFT may also be necessary to support the ISO application for XBT. As leaders of financial innovation through their Innotribe initiative, early indications from SWIFT senior management are that they would be supportive of such an application, if required.

Recently, the topic of XBT and the need to standardize various subunits has been much debated on Reddit and other social media outlets, unfortunately causing more confusion than clarification. Let's examine some of the top-level issues.

Why was XBT selected and what happens to BTC?

The code XBT was selected because the prefix 'X' denotes a non-national affiliation or a monetary metal such as gold or silver. Technically, BTC would be unavailable due to the fact 'BT' already represents the country of Bhutan.

The first two letters of the code are the two letters of the country code (as with national top-level domains on the Internet) and the third is the initial of the currency itself. In the case of the dollar (USD), US represents the country and D represents the initial of the currency.

Most likely, BTC would still remain in colloquial usage because it is already widely recognized by the community. Just as slang terms for money exist around the world, BTC shorthand would be used similar to how 'bucks' or 'quid' are used for other currencies. In this scenario, I expect BTC to continue to represent one full bitcoin unit.

Why does XBT have to represent a full unit of bitcoin?

One XBT unit as listed and recorded within ISO 4217 would have eight subunits or decimal places to the right of the decimal point. The rationale for this is that a neutral global default for bitcoin around the world cannot deviate from the unit's representation on the block chain (as expressed in the reference implementation) and the bitcoin integer in the core protocol is not changing.

One bitcoin on the block chain must equal one bitcoin in the formal standards world or else processing errors would be potentially catastrophic.

Even though eight decimals was selected as the starting point for the bitcoin integer, that number may need to be increased over time and increasing the amount of decimal places for bitcoin would hardly be a contested issue by the miners when the time comes.

The code representation within ISO 4217 cannot be changed up and down due to the varying number of decimal places in the core protocol. It must remain static.

Bitcoin is correctly placed, alongside gold, as a digital cryptographic commodity. So, just as gold (XAU) may trade in some areas as kilos or kilograms, the global default standard for pricing and measuring quantities of gold bullion remains the troy ounce.

One troy ounce is currently defined as 31.1034768 grams and is equivalent to approximately 1.09714 avoirdupois ounces. XAU denotes one troy ounce of gold and 'XAU/USD' means the price of 1 troy ounce of gold in US dollars.

How are the subunits related to XBT and the ISO standard?

Despite the fact that several names for bitcoin's minor units have been proposed, only three of the minor units, or subunits, have achieved a consensus within the bitcoin economy.

The third space after the decimal point (10−3) is commonly referred to as 'millibit' or mBTC. The sixth space after the decimal point (10−6) is commonly referred to as 'bit' or μBTC. The eighth space after the decimal point (10−8) is commonly referred to as a 'satoshi', the smallest available amount of bitcoin today.

These existing minor units of bitcoin will be submitted in the ISO application for XBT and it is not required for all of the individual minor units to be submitted.

To better facilitate consumer applications, some bitcoin operators may elect to provide a choice for display preferences. Several applications and web sites, such as BitcoinAverage, already permit toggling between bitcoin and millibit for display purposes.

Recently, some exchange operators have also expressed an interest and willingness to display prices in bits, so that only two decimal places exist to the right of the integer. For instance, KnCMiner embraced the bits display option for its wallet app. These moves could be especially useful for accounting packages that typically accommodate only two decimal points.
 
Strong opinions exist on all sides for going to a bits display, a millibits display, or remaining with a full bitcoin display.

As a consensus emerges, it is also perceived as useful to utilize one expression for retail consumers and to maintain a full bitcoin expression for wholesale level or institutional trading. This structure is entirely achievable because dual display options can be easily adopted by software providers.

Bitcoin Foundation Financial Standards Working Group Leads the Way for Mainstream Bitcoin Adoption

Press Release
The Bitcoin Foundation, Inc.
Tuesday, October 7, 2014

WASHINGTON, D.C. (October 7, 2014) — The Bitcoin Foundation (/)’s Financial Standards Working Group is underway with chairperson Beth Moses, an aerospace engineer, formerly with NASA and now with Virgin Galactic, at the helm. The group’s priorities for 2014 Q4 and 2015 Q1 will focus on applying for ISO 4217 approval for a Bitcoin currency code as well as drawing up recommendations for a Bitcoin currency symbol and Bitcoin subunits.

“Standardization is an important step towards removing obstacles for mainstream adoption — this is especially true with a technology for financial innovation that is global in reach,” said Jon Matonis, Executive Director of the Bitcoin Foundation.

The first task of the Financial Standards Working Group will be to apply for ISO 4217 approval for a Bitcoin currency code. Obtaining an internationally recognized currency code for Bitcoin will enable more fluid international transactions and currency conversion. ISO 4217 is the International Standard for currency codes and currencies are traditionally represented as a 3-letter alphabetic code. Currently, BTC is the leading candidate as it is in common use globally. However, ISO 4217 standards expect a leading letter “X” for global commodities like gold (XAU) and emergent supranational currencies like the precursor to the Euro (XEU). To this effect, some leading foreign exchange tools and services have already adopted the leading code “XBT” such as Xe.com, Oanda and Bloomberg.

Secondly the working group will examine the options for and recommend a Bitcoin currency unicode symbol. A currency symbol (https://en.wikipedia.org/wiki/Currency_symbols) is a graphic symbol used as a shorthand for a currency’s name, especially in reference to amounts of money. Many are familiar with $ for USD, € for Euro and ¥ for Yuan. Currently, the leading symbols for Bitcoin are B , ฿, and Ƀ. The working group will deploy a consensus based process for reaching an agreement for the official currency symbol. In addition, the working group will recommend Bitcoin subunits. In a currency, there is usually a main unit (base), and a subunit that is a fraction of the main unit. Currencies today operate with two decimal spaces to the right ($1.00). In Bitcoin, there are currently eight so one could theoretically pay you 0.00000001 or one hundred-millionth of a Bitcoin. Not only is this confusing for consumers, it does not fit in existing systems and software for accounting practices.

With a shared goal of achieving standardization for mainstream adoption, the volunteer working group of 20 Bitcoin Foundation members is led by volunteer chair Beth Moses, who led the standardization and testing of extravehicular interfaces for the International Space Station while at NASA. Like the International Space Station, Bitcoin is an emerging technology with global implications that requires a shared, basic language in order to enable successful mainstream utilization.

The working group will be hosting roundtable discussions with industry leaders, experts, and stakeholders in the coming weeks.

12 Ways to Measure the Bitcoin Network's Health

By Jon Matonis
CoinDesk
Sunday, September 27, 2014

http://www.coindesk.com/12-ways-measure-bitcoin-networks-health/

The ultra-resilient bitcoin network is the world's largest distributing computing project in terms of raw computational power, having long ago surpassed 1 exaFLOPS (1,000 petaFLOPS) – over eight times the combined speed of the top 500 supercomputers.

Although since increasing to an amazing 3.2 zettaFLOPS (3,200 exaFLOPS), the project was quietly removed from Wikipedia's list of distributed computing projects. This is probably due to the fact that the exaFLOPS estimate breaks down with bitcoin's specialized ASICs, since they are not capable of floating-point operations.

Instead, the estimate may be used for estimating how well other supercomputers and distributed networking projects would be able to mine bitcoin, since supercomputers have the capability to perform the integer operations used in hashing.

Therefore, today's fastest supercomputer, China's Tianhe-2 with a performance of 33.86 Pflop/s, would measure at about 0.001% of the bitcoin network.

Monitoring network health

As bitcoin matures and starts to compete with legacy retail payments networks like Visa and MasterCard, and wholesale networks like Swift, the health of the decentralized network becomes vital to its performance capabilities.

Community site Bitcoin.org does an excellent job of maintaining the historical archive of network status alerts and vulnerabilities.

The assembled report below lists the critical statistics for monitoring the ongoing health of the distributed bitcoin network, covering the measurements important for reachability, scalability, security and transaction processing speed.

1. The Bitnodes Project

Bitnodes estimates the size of the bitcoin network by finding all the reachable nodes in the network. The current methodology involves sending getaddr message recursively to find all the reachable nodes in the network starting from a set of seed nodes. It performs this polling every 24 hours and displays the results on a world heat map of countries, including rankings and version of bitcoin reference client.

Nodes
Source: Bitnodes
The Bitnodes Project launched in April 2013 with the Bitcoin Foundation’s sponsorship as a community resource. The project's latest report can be seen here.

2. Data Propagation


Data propagation
Source: BitcoinStats
The information exchange in the bitcoin network is all but instantaneous. Exactly how fast is information being propagated in the network though? Maintained by BitcoinStats, the propagation evolution chart shows the 50th percentile of the inv-messages received by peers (ie: the plot shows the time since a transaction or block enters the network until a majority of nodes has received and processed it).

3. DNS Bootstrap Servers

DNS seeds are used by almost all bitcoin clients to identify a set of nodes to connect to when starting. The seeds are run by volunteers using a multitude of mechanisms to ensure the returned seeds represent a good sample of nodes currently online.

DNS servers
Source: BitcoinStats
Except for bitseed.xf2.org, the seeds aim to return nodes that are currently online and reachable. Also provided by BitcoinStats, the chart shows results from regular bootstrap attempts using the seeds with the plot representing the average hourly connection success rate for each of the seeds. The closer to 100%, the better the seed is.

An auxiliary chart with response time of DNS seeds to queries is also provided, which indicates the response times in milliseconds (ms) elapsed between sending the query and receiving a response.

4. Network Hashing Rate

Provided by developer Pieter Wuille, this series of graphs display hashing difficulty and the estimated number of terahashes per second (computation speed) that the network is performing for various time windows (1 terahash equals 1,000 gigahashes).
Hashing rate
Calculated by dividing maximum target by current target where target is a 256-bit number, difficulty measures how difficult it is to find a new block compared to the easiest it can ever be. Difficulty adjusts every 2,016 blocks (or two weeks) and to find a block, the SHA-256 hash of a block’s header must be lower than or equal to the current target for the block to be accepted by the network.

5. Hash Rate Distribution

This pie chart from Organ Ofcorti is an estimation of hash rate distribution amongst the largest mining pools at a weekly interval. It is important to monitor because the integrity of the network depends on a single actor not exceeding 50% of the overall hashing power.

Network blocks
Source: Organ OfCorti
A table of solved block statistics lists all statistics that can be derived from the number of blocks a hash rate contributor has solved for the past week. Block attributions are either from primary sources such as those claimed by a particular pool website, or secondary sources such as coinbase signatures, or known generation addresses.

When dependent on secondary sources only, data may be inaccurate and miss some blocks if a particular block-solver has gone to some trouble to hide solved blocks and this will result in an underestimate of the block-solver hash rate.

6. Selfish Mining Indicator

Produced by Coinometrics, this metric attempts to measure the likelihood and prevalence of bitcoin miners engaged in a subset behavior of the 'Selfish Mining' strategy, as described by Ittay Eyal and Emin Gün Sirer in their paper, Majority is not Enough: Bitcoin Mining is Vulnerable.

Since the bitcoin protocol relies on miners following the rules laid out by the software, as soon as miners have found a block they need to announce it to the network.

Selfish mining defies this rule, because certain miners, once they have found a block, can withhold it from the network and start working on their next block. Once they have a number in their hidden chain, they can release them to invalidate the blocks that the network thought were part of the main chain.

The lower the probability that at least k (actual distribution) blocks will be found in the time represented by the first bucket, the more likely that miners are engaging in quick succession behavior under the Selfish Mining strategy.

Coinometrics explains:
"One way to estimate the likelihood of such a strategy being implemented is to measure the distribution of the time between blocks against the expected distribution. The rate of creation of bitcoin blocks is determined by how quickly the first miner solves for a hash meeting the difficulty requirements of the protocol. Every attempt to meet this difficulty has a set probability of being correct. By definition, the probability is independent between hashes. As a result the rate at which blocks are generated should follow an exponential distribution."

7. Orphaned Blocks

Orphaned blocks are valid blocks which are not part of the main bitcoin block chain. They can occur naturally when two miners produce blocks at similar times or they can be caused by an attacker with enough hashing power attempting to reverse transactions.

Initially accepted by the majority of the network, orphaned blocks are those that are rejected after proof of a longer block chain is received that doesn't include that particular block. In other words, a user could see a transaction as having one confirmation and then revert to zero confirmations if a longer blockchain was received that didn't include the transaction.

8. Double Spends Monitor

Blockchain maintains a real-time monitor for double spends detected in the last 500,000 transactions utilizing a 10-minute cache. This could be used to alert users to potentially malicious transactions on the network.

9. Unconfirmed Transactions

Blockchain also maintains this live updating list of new bitcoin transactions waiting to be included in a block. The monitor displays total number of unconfirmed transactions, including total fees and total size in kilobytes.

10. Average Transaction Confirmation Time

This measures the average (mean) amount of time in minutes that it takes for a transaction to be accepted into a block. Reasonable estimates differ on the amount of time and confirmations for a transaction to be considered cleared and ‘good’, but that appropriate risk level would be associated with the transaction’s value.

11. Block Chain Total Size

The block chain total size is important because of the storage space considerations as it grows as well as the time it takes for initial synchronization after installing the reference client for the first time. This measurement shows total size of all block headers and transactions not including database indexes.

12. Average Block Size

Measured here in fractions of a megabyte, the block size will become a heated debate once the bitcoin network starts approaching its current throughput limit of approximately seven transactions per second.

Ultimately important for scalability, the stated block size limit will have to be increased, linked to another variable, or remain the same with more confirmations pushed off chain, each path having corresponding implications for decentralization of the system.
