How the Hunt for Satoshi Turned Dorian Nakamoto’s Life Upside Down: the Inside Story

Once More for Posterity: Dorian Nakamoto Explains Why He Is Not the Mastermind Behind the World's Most Popular Digital Currency

Approaching the home that Dorian Nakamoto shares with his 93-year-old mother in the small Los Angeles County suburb of Temple City, one beholds a posted note under the doorbell declaring, “Private property: No solicitors or reporters.” Though I have come as an invited guest, the note stands as a stark reminder of the peculiar form of hell Nakamoto endured just a year and a half ago, when he was hounded to distraction by hordes of media and various curiosity-seekers after Newsweek magazine published a purported exposé that dubbed him the “Father of Bitcoin.”

The claim fell like a bomb on those who follow Bitcoin, and given Newsweek ’s longtime status as a paragon of mass magazine journalism, it engendered widespread discussion. The article, by Leah McGrath Goodman, served as the magazine’s cover story on March 6, 2014. It claimed to have uncovered the true identity of Bitcoin creator Satoshi Nakamoto, following a two-month investigation that included “interviews with those closest to (Dorian) Nakamoto and the developers who worked most frequently with him (“Satoshi”).

Citing Dorian’s past contracting work on top-secret engineering projects, an ingrained disdain for government intrusion, and using quotes from various family members which paint him as a humble, privacy-obsessed engineering mastermind, Goodman made a compelling though surface-level argument for Dorian Nakamoto as the creator of Bitcoin.

But following the article’s publication, most involved with Bitcoin were quick to question the validity of Goodman’s claims, seeing the evidence presented as largely circumstantial. A commonly held belief among those who are skeptical of Newsweek ’s claims is that “Satoshi Nakamoto” is actually an alias for a group of cryptographers/software engineers, rather than an individual. Others who corresponded with “Satoshi,” including core developer Gavin Andresen, believe he is in fact an individual.

Furthermore, a recent piece by Nathaniel Popper in The New York Times makes the case that if the creator was indeed an individual, he was probably BitGold inventor and noted cryptocurrency expert Nick Szabo, not Dorian Nakamoto (although Szabo, too, refutes these claims).

Still others have asked the logical question of why a humble and essentially private person such as Dorian Nakamoto would create Bitcoin, seek anonymity for that feat, and then choose an alias that includes his given last name, in light of all of the other measures he took to remain anonymous.

Mike Hearn, a developer who communicated with Satoshi prior to his departure from Bitcoin, even posted a blog entry that charted logical inconsistencies within Goodman’s claim that Dorian Nakamoto and Satoshi Nakamoto are one and the same.

Trial By Media Fire

The Newsweek story revealed sensitive details about Dorian Nakamoto in an effort to highlight personality traits and motivations that fall in line with what little there is to infer about Bitcoin’s creator. It ended up turning his world upside down.

In the midst of an unwanted media blitz that included what he describes as being unable to grab milk from the store without being barraged by reporters, Nakamoto gained support from lawyers and individuals in the Bitcoin community. One group even created the short-lived website “newsweeklied.com” that was intended to clear his name and raise funds for a lawsuit against the publication giant.

In a statement formally submitted to Newsweek by Nakamoto and his lawyer, he states that he “did not create, invent or otherwise work on Bitcoin,” and that, “Newsweek ’s false report has been the source of a great deal of confusion and stress for myself, my 93-year-old mother, my siblings, and their families.” He then ends the letter: “This will be our last public statement on this matter. I ask that you now respect our privacy.”

Given the definitive nature of that statement, I ask Dorian why he now desires to speak to the press. His simple answer: “Closure.”

Cookies and Courtliness

As we enter Nakamoto’s home, he leads me into the kitchen, where the table is neatly set with woven placemats, a Japanese style tea set and a box of chocolate chip cookies. It is immediately apparent that Nakamoto, 65, a bachelor with a past marriage and grown children on his family resume, may not regularly entertain new guests in such a quasi-formal setting, but he has his own sense of how to go about doing so. He exudes a kind of courtliness, reverence and respect for the occasion that young people today would likely describe as “old-fashioned.”

As I take my seat, he is quick to offer and pour me green tea, then proceeds to make sure that I am content and comfortable in a way that feels refreshingly sincere. Not drinking any tea himself, he settles into his seat and begins to form circles around the empty cup with his fingers. Far from the shrewd, eccentric man portrayed in the Newsweek piece, he appears much more as a kind and good-humored person, with an almost canonical approach to respect and hospitality. After an exchange of additional basic pleasantries, he chuckles to himself and says in his slow, deep voice, “OK. Ask me anything.”

At the crux of Newsweek ’s claim that Nakamoto is in fact the creator of Bitcoin is a brief exchange between Goodman and him, in which Goodman states that he “tacitly" acknowledged his role in the Bitcoin project by declaring to her: “I am no longer involved in that and I cannot discuss it. It’s been turned over to other people. They are in charge of it now. I no longer have any connection.”

The words “no longer involved” and “turned over” would seem to lend credence to the belief that Nakamoto was in fact involved in some capacity with the “Bitcoin project.” I ask him about this exchange specifically, seeking to gain some clarity on his response. He replies: “I was thinking about work I had done at Citibank that was security things, security exchange. Even if I was involved I can’t tell you, because every engineering firm makes you sign a nondisclosure contract for during and post. I thought maybe that [her question] was something to do with Citibank work that I did.”

This response provides potential clarity surrounding this pivotal exchange between Goodman and Nakamoto. He insists he was not even familiar with the term “Bitcoin” at the time of the Newsweek interview, and thought Goodman was referring to a project that he had worked on at Citibank. Why, at the time, he drew this conclusion about the connection between “Bitcoin” and his previous, confidential work for Citi is still not entirely clear.

The Case for and Against

The Newsweek piece emphasizes: “Perhaps the most compelling parallel between the two Nakamotos are their professional skill sets and career timeframes.”

While portrayals of work on classified military projects are commonly projected with an almost clichéd, sinister tone, Nakamoto’s’s reasons for the life of secrecy described by his family are far more practical than they are mysterious. In addition to the nondisclosure agreements he signs with each classified project, and his firm belief in abiding by what he describes as the “engineer’s code,” he also emphasizes that it is extremely advantageous for people in his line of work to be as private as possible in order to best preserve their job security.

In this and his other responses, it is clear that Nakamoto has the mind of an engineer, articulating each of his carefully constructed thoughts piece by piece, and attending to even the most seemingly minute details. Noting the measures that his employers take to ensure that contractors will not be motivated to exchange classified information for rewards, he explains how anything from debt to a troubled relative or an affair (remember David Petraeus’s exit from the CIA?) would be grounds for immediate removal, and likely result in permanent exclusion from classified projects.

He notes that since publication of the Newsweek article, which exposed many personal details including sensitive information about his health and finances, he has been effectively “blacklisted” from the types of engineering jobs that he has worked on throughout his professional career.

Respect for the “Bitcoin Creator”

While the unwanted association with Bitcoin has brought significant hardship and stress to Nakamoto’s life, he brightens and is eager to thank the Bitcoin community for their “support.” He then expresses appreciation toward the “creator” for bringing Bitcoin’s blockchain technology to the world.

“The more I study about it, I think it’s a fantastic idea. I really appreciate what he [Satoshi Nakamoto] did, and all the people who contributed, including [Bitcoin core developer Gavin] Andresen and Andreas [M. Antonopoulos, Bitcoin entrepreneur and security expert].”

Warming to his topic, he continues: “And then the free software, freeware--that is a brilliant idea on the part of this creator or group of creators. But you also need very talented people to implement and carry it out; also marketing, sales. I just feel when I looked at it, I said ‘Wow! This is a beautiful thing.’ Especially if you are anti-authority or anti-establishment, which would be banks and governments and things like that. And they [Bitcoin] have a hold of young people now, including Jeffrey right here!

“I’d like to see how Bitcoin evolves into the next stage. How it encounters this problem, I won’t say problem, but government is always trying to encroach. Same thing with banks. And we will have to withstand the storm of what’s going to happen to our dollars as the international standard exchange currency….The biggest thing is we can’t possibly pay,” he says, in reference to the American debt. “My hope is that the top level designers, the creators, think about that.”

I am astonished to hear that Nakamoto has such high praise for the technology, and moreover, that he has clearly thought about how it should evolve, drawing on the nuances of the economic implications surrounding a decentralized currency/monetary system, and in light of the current geopolitical environment.

Riding Toward a Powerful Future

Nakamoto’s car, a faded beige Toyota Corolla, which “still runs great” after having logged almost 200,000 miles on the odometer, is not his preferred method of transportation. Driving to grab some Chinese food in Temple City, he points out the flawed street design and cracked sidewalks that obstruct his frequent bike rides around town.

Chuckling as he explains what he sees as simple solutions to basic infrastructure problems, he notes the pleasure and peace he finds in his regular bicycle rides, smiling as he recounts past excursions through the San Gabriel foothills and on the banks of the Los Angeles River. (Yes, there is such a thing, but it is mostly a wide concrete channel traversing the L.A. basin.)

In his New York Times piece, Popper states, “At this point, the creator’s identity is no longer important to Bitcoin’s future.” While most Bitcoin observers would likely believe this to be true, it is also clear that the unique mindset, convictions and motivations that governed “Satoshi’s” approach have had a meaningful, lasting effect on the enterprise, and they warrant examination. In this regard, Satoshi Nakamoto becomes more than the "genius” (or geniuses) who created Bitcoin—he also created Bitcoin, took no credit, and left the fortune amassed by his own creation completely untouched, all in order to best preserve the purity of a powerful idea. And that is a world-changing thing, quite likely unique in human history.

It is almost impossible for most of us to imagine a person or group who would have both the technical skill set to create Bitcoin and the ability to faithfully execute on such selfless principles. This draws us to figures like Nick Szabo and Dorian Nakamoto. Both men’s personalities and beliefs align with the characteristics that make Satoshi Nakamoto such a uniquely compelling figure. While such investigations are, for these reasons, entertaining and thought-provoking, they do clearly affect—in Dorian’s case, severely affect—the individuals under examination.

Moreover, such attempts to unveil the creator’s identity go against (what appears to be) Satoshi’s desire for Bitcoin to evolve as a truly inclusive open source project, in which the actual identity of its creator is ultimately unimportant.

With all that said, I am glad I was able to spend a day with Dorian Nakamoto in Temple City. I hope that this account will shed some light on Newsweek ’s so-called “Father of Bitcoin,” and perhaps help provide him with the closure that he seeks. If so, it couldn’t happen to a humbler guy.

Australian Startups Close Down as Banks End Support for Bitcoin

Australia’s largest banks have ended all financial support and abruptly closed down the bank accounts of at least 17 Australian Bitcoin companies, including the Australian Digital Currency Commerce Association Chairman Ron Tucker’s Australian bitcoin exchange Bit Trade.

“The banks had not advised any of our members. To the best of our knowledge all, or nearly all digital currency businesses have received letters from their bank, or in many cases banks, advising of the closure of their accounts. This includes at least 17, with 13 of these closed permanently,” Tucker told Bitcoin Magazine.

Major Australian banks, including Westpac Banking Corporation and Commonwealth Bank of Australia, have not announced their motivations behind the termination of banking support for bitcoin companies. This incident has attracted the attention of the Australian Competition and Consumer Commission (ACCC) and Senator Matthew Canavan, who sees the sudden pronouncement of the bank as an unlawful act, and has requested the ACCC to launch a full investigation on the banks.

“Whilst we're unable to comment on the banks’ motivations (that is for them to explain) however, the consequences of these moves are becoming more clear. The Australian Bitcoin industry, as part of a larger revolution in financial technology, has seen its growth severely curtailed by this unexplained wave of debanking,” Tucker added.

Startups Begin to Leave Australia

“Unfortunately most digital currency startups have already shut their doors in Australia as no alternative banking solutions were available. In at least one case, one Bitcoin company, Coinjar, did relocate its head office to a more welcoming market in the U.K.,” Tucker told Bitcoin Magazine.

Most Australian Bitcoin startups offer bitcoin exchange services and merchant bitcoin payment processing; two of the few bitcoin-related services which require banking or credit card support. Although some bitcoin startups have begun to search for alternative financial institutions and organizations to maintain their operations, most companies have failed to secure banking service partnerships.

“Presently the industry here in Australia have no alternative options despite best efforts of our members to reach out to various banking sector participants,” added Tucker.

No Clear Justification

Labor Senator and a member of the Senate Economics References Committee Sam Dastyari showed his concerns toward the banks, due to their lack of explanation and justification behind the abrupt termination of banking support.

"I am concerned that there is an allegation that Australian banks are deliberately choking small businesses, while setting themselves up to offer the same services. We don't have a four-pillars policy to allow banks to guillotine emerging industries they are competing with … These small local digital currency companies are essentially competing to provide trading platforms, and develop emerging technologies,” explained Dastyari .

The Australian Digital Currency Commerce Association strongly believes that the banks owe an explanation and a clear justification behind the “debanking” of the companies. Currently, all Australian major banks have terminated banking support for Bitcoin companies.

“Our members have said the banks have been remarkably unwilling to provide explanations for ceasing to provide services for ADCCA members. Our members, some of whom may end up being partners with or competitors to the banks in the future, are currently at the mercy of established financial institutions. At the very least I think our members are owed an honest explanation of why they are being debanked,” Tucker said.

Beyond Bitcoin: How the Blockchain Can Power a New Generation of Enterprise Software

This is a guest post by Jesus Rodriguez.

Bitcoin has become one of the most intriguing and revolutionary technologies created in the last few years. From a functional standpoint, the cryptocurrency has challenged the most fundamental principles of the world’s financial systems by providing a decentralized, secured and trusted model to process financial transactions. To enable its magic, Bitcoin relies on an architecture powered by a groundbreaking technology known as the blockchain.

While bitcoin has clearly become the most important implementation, it is just one of many practical applications that can be powered by the blockchain. From the conceptual standpoint, the blockchain provides a series of capabilities that can change some of the well-established architectures in the enterprise digital world.

How can the blockchain redefine enterprise?

The decentralized, autonomous, trusted and secured capabilities of the blockchain can redefine the foundational patterns of enterprise applications. While the principles of the blockchain are well-understood patterns in enterprise solutions, until now we have lacked practical implementations that validate its functionality at an enterprise scale. The blockchain opens a new set of opportunities to enterprise scenarios that weren’t possible before. However, in order for blockchain solutions to be embraced in enterprise, they will have to develop a series of key capabilities to get past traditional IT compliance and regulatory practices.

What’s needed to adopt the blockchain in enterprise?

Despite its unique value, the process of adopting blockchain solutions in enterprise is far from trivial. Like many other technology trends, blockchain solutions will have to develop a series of enterprise-ready capabilities to be adopted in mainstream business scenarios. Those enterprise-ready capabilities are called to address many requirements in areas such as management, operational readiness, or compliance, which are essential to adopt solutions on different industries. The following list includes some of the key capabilities required to adopt the blockchain in mainstream enterprise scenarios.

  • Development Platform: The blockchain is a very complex architecture modeled in terms of transactional exchanges. To mitigate that complexity, we need programming frameworks and languages that allow average developers to build general-purpose applications against the blockchain.
  • Monitoring Tools: To be adopted in enterprise settings, the blockchain community should produce solutions that can actively monitor the health of a blockchain network and recover from unexpected failures. These capabilities will allow organizations to monitor the runtime behavior of blockchain solutions.
  • Private Cloud Deployments: Facilitating the deployment of the blockchain in private cloud topologies using mainstream enterprise infrastructures is a key element to facilitate the wide adoption of blockchain solutions in the enterprise. In that sense, the blockchain should work seamlessly with technologies such as Docker, VMWare vCloud, Open Stack among other mainstream enterprise infrastructure platforms.
  • Standards: As organizations start adopting blockchain solutions, the need to have standards will become increasingly relevant. Standards will facilitate the interoperability between different blockchain platforms while also enabling important security and compliance requirements of enterprise solutions.
  • Interoperability with Well-Established Enterprise Platforms: Like any other enterprise software trend, blockchain solutions will be required to integrate with established enterprise platforms like databases, line of business systems, etc. Enabling that interoperability will be essential to power the adoption of blockchain solutions in the enterprise.

10 Enterprise Scenarios that can be Redefined by the Blockchain

Decentralized IoT

The Internet of Things (IoT) is becoming one of the most important trends in modern enterprise software. While many IoT platforms are based on a centralized model in which a broker or hub control the interaction between devices, this model has proved to be impractical for many scenarios in which devices need to exchange data between themselves autonomously. That specific requirement has been the fundamental principle behind decentralized IoT platforms. Those decentralized models are fundamentally powered by a trusted ledger of exchanges between smart devices fundamental to power real-world IoT solutions.

The blockchain provides foundational capabilities of decentralized IoT platforms such as secured and trusted data exchange as well as record-keeping. In this type of IoT architecture, the blockchain will serve as the general ledger, keeping a trusted record of all the messages exchanged between smart devices in an IoT topology.

Keyless Signature

Public Key Infrastructure (PKI) has been one of the fundamental technologies powering data signatures. PKI models rely on a central authority to stamp and validate signatures on a data payload. While PKI models have been incredibly successful, the dependency on a central authority presents serious limitations for large-scale scenarios and is also vulnerable to attacks involving quantum computation.

The characteristics of the blockchain can help to overcome some of the limitations of PKI models with a keyless security infrastructure (KSI). A KSI model uses only hash-function cryptography, allowing verification to rely only on the security of hash functions and the availability of a public ledger commonly referred to as a blockchain.

Data Archiving

Archiving historical data in a secure and trusted manner has been a permanent challenge of enterprise IT. Companies like EMC have become one of the most iconic enterprise software companies in history by providing robust storage and archiving solutions. More recently, cloud platform vendors such as Amazon have provided alternative data archiving solutions. However, in both cases, data archiving solutions rely on a centralized storage model, which has well-known limitations in enterprise scenarios in areas such as security and privacy.

Decentralized and autonomous data archives models, such as the ones provided by the blockchain, can be an interesting alternative to centralized data storage solutions. This model will eliminate the dependency on a centralized authority and will allow distributed and trusted storage across nodes in a blockchain network. More importantly, using the blockchain as a data archive will allow any nodes to validate the authenticity of the archived data without relying on central hub.

Decentralized B2B Auditing

Business-to-business (B2B) exchange models are one of the foundations of modern commerce. In those scenarios, transaction tracking, auditing and reconciliation processes are essential capabilities of B2B processes. Traditional B2B platforms enable these capabilities by providing centralized transaction tracking models that will be used by the different B2B endpoints to log relevant events of a specific transaction. These centralized tracking models have proved to be impractical to address many of the typical challenges of B2B transaction tracking processes in areas such as auditing and reconciliation.

Leveraging the blockchain as a decentralized, secured and trusted transaction ledger could be a more effective model to address the challenges of B2B transaction tracking solutions. Using the blockchain, each party in a B2B process could autonomously track the events related to a B2B transaction without the need to rely on a centralized authority. Additionally, the security capabilities of the blockchain will facilitate the implementation of more sophisticated reconciliation and auditing processes.

Legal Proof of Existence or Proof of Possession

Validating the existence or the possession of signed documents is an incredibly relevant element of legal solutions. The challenge of traditional document validation models is that they relied on central authorities for storing and validating the documents, which presents some obvious security challenges, but also becomes more difficult as the documents become older.

The blockchain provides an alternative model to proof-of-existence and possession of legal documents. By leveraging the blockchain, a user can simply store the signature and timestamp associated with a document in the blockchain and validate it at any point using the native blockchain mechanisms.

Distributed File Storage

Cloud file storage solutions such as Box, Dropbox or One Drive are becoming regular citizens of modern enterprise environments. Despite its popularity, cloud file storage solutions typically face challenges in areas such as security, compliance and privacy in order to be adopted in enterprise environments. Those concerns are all rooted behind the fact that enterprises need to trust a third-party cloud system with their confidential documents.

Security Trade Settlement

Central Security Depositaries (CSDs) have been an essential element of modern equity and bond trading. In the U.S. equity market, following frequent bottlenecks during the late 1960s in the settlement of securities trades, CSDs smoothed the post-trade process for transferring share ownership by eliminating the exchange of paper certificates and recording transactions in central, computerized book-entry systems. The international CSDs Euroclear and Cedel (now Clearstream) played a similar role in the Eurobond market from the 1970s onward.

The centralized nature of CSDs is essential to successful bond and equity trades. However, the settlement process via CSDs is incredibly expensive and slow, averaging two or three days per trade settlement.

The blockchain offers an interesting alternative to traditional CSDs as a decentralized ledger that can keep records of transactions without relying on a central authority. The query capabilities of the blockchain will allow the settlement of trades in minutes or even seconds and at a fraction of the cost of the current CSD solutions.

Anti-Counterfeiting

Counterfeiting remains as one of the biggest challenges in modern commerce. Segments like luxury goods, pharmaceutical or electronics are constantly affected by counterfeiting. As a result, the demand for anti-counterfeiting remains one of the hottest topics in the digital commerce world. Unfortunately, most solutions in the market require a trust in the third-party authority, which introduces a logical friction between merchants and consumers.

The decentralized and security capabilities of the blockchain can enable an interesting alternative to traditional anti-counterfeiting platforms. In that sense, we can envision a model in which brands, merchants and marketplaces are part of a blockchain network with nodes storing information to validate the authenticity of specific products. In this model, brands don’t have to trust a central authority with their product authenticity information and can rely on the security and decentralized trust models of the blockchain.

eGoverment

Governments all over the world are investing deep resources to digitize many of their existing processes. Many of these processes deal with sensitive information that require sophisticated levels of traceability, privacy and security. Inevitably, the digital collaboration process relies on trust on centralized authorities.

The blockchain capabilities provide a robust option to enable the digital collaboration between government agencies and citizens. In this model, different government agencies can store records in blockchain nodes so that it can be accessed and verified by other government parties and citizens in a secure and trusted way.

P2P Commerce

Traditional ecommerce business models are based on the presence of a centralized entity that control activities such as order processing, inventory management, catalog access, etc. In order to buy and sell goods, ecommerce marketplaces need access to sensitive user information such as credit card information, user profile data etc. This information often becomes the target of cybersecurity attacks and many other security and regulatory challenges.

The architecture of the blockchain can enable the first effective peer-to-peer (P2P) ecommerce network in which buyers and sellers can interact directly without the need of a central authority. The absence of a central marketplace eliminates many of the restrictions of ecommerce models such as fees, regulated transactions, etc.

Summary

The blockchain represents one of the most important advancements in computer science of the last few years. The ability to enable decentralized, secure, trusted and highly scalable architectures opens the door to a new group of enterprise software solutions on a large number of industries. Blockchain-powered solutions have the opportunity to challenge some of the fundamental architecture principles of enterprise solutions in areas such as security, data storage, trust, etc. Similar to Bitcoin, we should expect to see spectacular platforms in the enterprise software space powered by the blockchain.

Bitcoin Used to Pay Utility and Credit Card Bills in the Philippines and Australia

Over the past year, bitcoin startups in the Philippines and Australia have begun to target day-to-day expenses and remittances; markets that are in desperate need of instantaneous, secure and cost-effective payment systems.

Startups including Australia-based Living Room of Satoshi and Manila-based Rebit.ph, also known as the parent company of Bills Ninja, have been trying to educate the global population to use bitcoin in day-to-day expenses, such as paying utility bills and settling bank payments.

Paying Bills with Ease

Earlier this year, Rebit.ph acquired bitcoin bills payment platform Bills Ninja, to allow its users to settle rental, tuition, and electricity and credit card bills abroad. The service has been used by Filipino expats working in countries including Canada, UAE, Singapore, Hong Kong, Austrailia and Canada.

“Using Bitcoin, we've made it easier for Rebit users to send targeted remittances. A good number of remittances coming from overseas Filipino workers are intended for bills payments anyway. By enabling our users with this service, we've made it more convenient by eliminating that second step for them,” Rebit.ph CEO John Bailon told Bitcoin Magazine.

An official with Satoshi Citadel, the parent company and investor of Rebit.ph told Bitcoin Magazine that the Philippines-to-Canada, -Hong Kong and -Singapore remittance markets are huge, and that there are hundreds of thousands of Filipino employees working in these countries to support their families in their homeland.

Quite often, these expat workers pay utility bills such as water and electricity and credit card bills directly from these countries, using the Rebit.ph platform or the Coins.ph platform, which is currently ranked among the top 300 most popular websites in the Philippines.

Coins.ph, a competitor of Rebit.ph has seen a huge success through its partnerships with local banks, remittance outlets and financial institutions. The platform enables users to pay utility bills and cash out bitcoin at any of its supported outlets, including thousands of ATMs from the nationwide Security Bank and remittance outlets from Lhuiller and Palawan Pawn Shop.

However, Bailon told Bitcoin Magazine that its platform is different from services such as Coins.ph, because of its over-the-counter transactions for remittances and bills payments.

“Coins.ph allows people to load funds into and draw from their mobile money wallet, while Rebit is closer to the current user experience of an electronic over-the-counter transactions for remittances and bills payments,” Bailon explained.

Currently, many local residents and employees prefer to pay bills at local establishments and institutions. However, the Rebit.ph team says that the local residents are starting to recognize the advantages of bitcoin and bitcoin bills payment systems.

“There needs to be a paradigm shift in consumer behavior when it comes to electronic bills payments. Most Filipinos still pay their bills in-person at establishments even though they actually have access to more convenient methods. We're getting there, and when more and more people start to realize the convenience of electronic bills payments, Rebit is here to allow them to do it over the blockchain,” said Bailon.

Living Room of Satoshi

Living Room of Satoshi, Australia-based bills payment platform allows anyone to pay any Australian bill using bitcoin. The platform has been providing bitcoin bills payment service in all sectors, including shopping, entertainment, banking, Internet, electricity/gas, rent, tax, insurance and water.


The platform has been welcomed and used by Australian residents across the country. In a recent interview with Bitcoin Magazine, Australian farm Buda Foods founder and CEO Mark Burgunder said:

“We currently have a great service available here called Living Room of Satoshi that allows us to make bill payments and electronic transfers to almost any bank account in Australia using bitcoins. We've been using this service on a number of occasions already with the largest purchases so far having been for chicken feed and for mobile electric fencing.”

Many bitcoin enthusiasts and startups in the Philippines and Australia believe that the key to mainstream success for bitcoin is to educate the general population about its advantages, and encourage people to use bitcoin for day-to-day expenses.

Building a Risk Market for the Digital Age Using Bitcoin

This is a guest post by Michael Folkson.

The Internet was originally developed as a network for information exchange. Now, a multitude of entrepreneurs and software developers are building the Internet for value exchange. The next logical progression is to build the Internet for risk exchange.

Just as units of currency can be transferred to a third party, insurance contracts transfer risk exposures to a third party. Blockchain technology has the potential to radically transform how the insurance industry operates and how risk exposures are shared and distributed.

While Bitcoin offers a protocol for peer-to-peer value transmission bypassing the traditional banking system, an insurance industry leveraging a public blockchain presents an opportunity for individuals and entities to retain, share or transfer risk exposures without the requirement for risk exposures to sit on an insurance company’s balance sheet.

Science fiction frequently offers inspiration for what an industry could look like in the future. The short speculative fiction titled "Know When to Hold ’Em" by K.G. Jewell is a somewhat dystopian vision of futuristic insurance, but it does explain how the user interface of a peer-to-peer insurance market could operate.

In the story, the lead character, Jonas, acts as an insurer on the platform MicroRisk. Among the microrisks he chooses to provide insurance coverage for are vacation sickness, exam results, fashion (two individuals wearing the same outfit at an event) and being stood up on a first date. He is required to post collateral into his MicroRisk account before insuring a risk and is able to audit claims before paying out on them. The policyholder’s premium and the insurer’s collateral are frozen in escrow until the contract closed.

Some of these risks may be difficult to price due to limited data and increased moral hazard. However, the story does stir the imagination when envisaging what personal risks could be insured if the requirement to go through a conventional insurance company was lifted.

The transfer and distribution of risk dates back to at least to the second millennium B.C. In approximately 1750 B.C. Mediterranean sailing merchants paid their lender an additional sum to agree to terminate their liability conditional on the shipment being stolen or lost at sea.

There are a number of participants in today’s insurance industry. Brokers act as intermediaries to connect insurance buyers and sellers. Underwriters determine the premiums that should be charged in conjunction with the actuaries who also estimate the reserves required to meet future claims on an ongoing basis. Claims adjusters verify the legitimacy of insurance claims and assess the size of the payout.

There are many parallels between the banking and insurance industries with both sectors rewarded for accepting risk exposures. Rather than lending out funds and (hopefully) receiving them back at a future point in time, insurance companies receive funds in advance and return them contingent on future events.

The peer-to-peer lending model has thrived in recent years with companies such as Lending Club, Prosper and Zopa facilitating more than $1 billion of loans between individuals.

Its success is at least partly explained by re-establishing a direct link between investors and specific credit risk exposures at a time of economic uncertainty, sovereign debt crises and complex too-big-to-fail banking institutions. These direct credit risk exposures allow an investor to diversify her overall portfolio, and there are minimal infrastructure costs in comparison to traditional retail banks.

Similarly, a peer-to-peer insurance platform re-establishes a direct link between investors and specific insurance risk exposures. Today’s insurance companies are so large, complex and heavily regulated that the direct link between an investor and specific insurance risks has eroded. If an investor wants exposure to insurance risk to diversify her portfolio, she has little option but to invest in the shares of an insurance group and be exposed to multiple insurance risks in addition to asset risks such as sovereign bonds.

It is extremely difficult to match an investor’s risk appetite with specific insurance risks such as personal or commercial, home, car, health or travel. Moreover, it is impossible for an investor to opt out of specific risk exposures. The only insurance risks investors can get direct exposure to are credit and catastrophe risk through the issue of catastrophe bonds.

The peer-to-peer insurance model offers investors an opportunity to generate higher investment returns, transparency with regards to risk exposures and the satisfaction of directly insuring individuals or businesses rather than investing in a faceless insurance company. It offers policyholders access to cheaper premiums, faster claim payments and insurance coverage that might not be available through traditional channels.

Satoshi Nakamoto’s primary achievement of preventing users spending the same bitcoin on multiple occasions ("double spending") without a reliance on a trusted third party is a historic feat. However, it is worth emphasizing the obvious that the protocol does not wholly eradicate reliance on trusted third parties for all financial contracts.

For example, escrow mechanisms that are easily built using the Bitcoin protocol may still require dispute resolution if there is a disagreement over whether the goods or services delivered are of sufficient quality.

Nevertheless an escrow transaction built on a Bitcoin-like blockchain could be a template for how future insurance contracts are constructed. The insurance buyer and the insurance seller could transfer the premium and the collateral respectively into a multi-signature (2-of-3) Bitcoin wallet. The third signatory to the wallet would be the arbiter. Funds would be released from the wallet conditional on two parties signing the transaction, preventing the buyer, seller or arbiter from fraudulently seizing the funds.

Just as the execution of a standard escrow contract will rely on an arbiter to resolve disputes between the buyer and the seller, the execution of an insurance contract relies on claims adjusters to verify that incoming claims are valid and if necessary estimate the monetary value of the claim.

This service will vary from reviewing evidence submitted by the claimant to physically inspecting the scene of the insured event depending on the magnitude of the claim. It is currently difficult to automate this function, and artificial intelligence is not yet advanced enough to rebuff all human attempts of fraudulent submissions.

Decentralized platforms heavily rely on the efficacy and dependability of reputation systems. The upside of bypassing centralized services such as eBay, Kickstarter or Uber is that no third party can charge excessive fees, impose restrictive policies, prohibit bitcoin payments or present a single point of failure in the storing of users’ personal data.

However, the downside is that no organization is responsible for maintaining the integrity of the system. Instead a mixture of user feedback, reputation scoring and financial incentives must be combined to construct robust reputation systems. The alternative is to build quasi-decentralized systems that may be an improvement on centralized systems but don’t accrue all the benefits of purely decentralized systems.

For example, the various activities of an insurance company could be unbundled so that some activities are automated while others are outsourced to external providers. It may be the case that quasi-decentralized systems will need to be built as an intermediate step or that optimal systems will never be purely decentralized. However, it makes sense to fully explore all the options and capabilities of this technology before falling back on how current systems already operate.

Although private blockchains (or ‘permissioned distributed ledger systems’) are useful for keeping databases in sync in a more trusted environment, they are an incremental innovation when compared to the potential of public blockchains. Just as Bitcoin opens the floodgates for peer-to-peer transactions and permissionless innovation, peer-to-peer insurance leveraging a smart contracts protocol could provide a platform for matching insurance buyers and insurance sellers for any risk they agree to exchange.

This marketplace would be a radical paradigm shift from today’s centralized and spatially anchored insurance industry. The blockchain provides the opportunity to build a more innovative, expansive and transparent industry that evolves to the needs and requirements of its users.

R3 Blockchain Development Initiative Grows to 22 Banks Worldwide

The international R3 blockchain project to develop blockchain commercial applications and standards for the financial world just got a whole lot weightier as 13 new global banks joined the distributed or “shared” ledger initiative.

R3, the international financial innovation firm, based in New York, London and San Francisco, is a multidisciplinary team including experts from the worlds of electronic banking, new tech startups, and cryptography and digital currencies development, aiming to “define, design and deliver the next generation of financial technology.”

The 13 new banks joining the project are:

  • Bank of America
  • BNY Mellon
  • Mitsubishi UFJ Financial Group
  • Citi
  • Commerzbank
  • Deutsche Bank
  • HSBC
  • Morgan Stanley
  • National Australia Bank
  • Royal Bank of Canada
  • SEB
  • Societe Generale
  • Toronto-Dominion Bank

These banks join current project members Barclays, BBVA, Commonwealth Bank of Australia, Credit Suisse, Goldman Sachs, J.P. Morgan, Royal Bank of Scotland, State Street and UBS.

“The addition of this new group of banks demonstrates widespread support for innovative distributed ledger solutions across the global financial services community, and we're delighted to have them on board," R3 CEO and former ICAP Electronic Broking CEO David Rutter said in a press release.

"We have placed an emphasis on working with the market from day one, and our partners recognize that a collaborative model is the best way to quickly, efficiently and cost-effectively deliver these new technologies to global financial markets," Rutter said.

As Bitcoin Magazine previously reported , Rutter has recruited Nichola Hunter, former ICAP trading executive; Richard Brown, a technology expert formerly with IBM UK; and Tim Swanson, a U.S.-based cryptocurrencies consultant, to work in a collaborative lab environment or "sandbox" to test and validate blockchain applications, prototypes and protocols.

This major project brings together not only the experts, but also the considerable resources of 22 big banks to collaborate on “research, experimentation, design and engineering to help advance state-of-the-art enterprise-scale shared ledger solutions to meet banking requirements for security, reliability, performance, scalability and audit.”

Transaction Remote Release, a Tor-Inspired Proposed Change to Bitcoin Protocol for Anonymous Transactions

It’s well known that bitcoin transactions are not anonymous. Every transaction and the full transaction history of any bitcoin address are permanently recorded in the tamper-proof public blockchain and open to analysis. A bitcoin addresses isn’t explicitly associated to its owner, but blockchain network analysis can often de-anonymize bitcoin users.

Bitcoin Magazine recently reported that two companies, Chainalysis and Elliptic , sell sophisticated blockchain network analysis tools and services to trace bitcoin transactions back to their participants, and de-anonymize users. Such services often anger libertarian early adopters, but the direction of the evolutionary trend in the Bitcoin space is clear – governments and financial institutions are gradually warming up to blockchain technology as a means to achieve faster, cheaper and better recorded transactions, but consider privacy and anonymity as bugs that need to be fixed.

Recommended privacy practices, from simple measures such as using fresh Bitcoin addresses for new transactions to strong privacy measures such as dark wallets and mixing services, reduce the risk of being de-anonymized, but there are documented attack strategies that often permit identifying bitcoin users by IP. Using the Tor network provides additional privacy protection by masking the user’s IP, but ways to work around Tor privacy have been found.

Now two researchers from the ATR Defense Science & Technology Lab at Shenzhen University, in China, have published a white paper titled “Transaction Remote Release (TRR): A New Anonymization Technology for Bitcoin .” The researchers propose a new anonymization technology called Transaction Remote Release (TRR). Inspired by Tor, TRR is able to render several typical attack strategies ineffective. “Furthermore, the performance of encryption and decryption of TRR is good and the growth rate of the cipher is very limited,” say the researchers. “Hence, TRR is suited for practical applications.”

“In the Bitcoin protocol, the only way that the attackers can connect the Bitcoin address with an IP address is in the process of releasing and spreading a new transaction,” note the researchers. Therefore, they propose to encrypt the new transaction and obfuscate the source IP of the sender.

TRR is inspired by the idea of encryption and decryption layer by layer as used in Tor. A client encrypts a new transaction, layer by layer, using the public key from different TRR nodes. Then it establishes an independent connection to other TRR nodes, one by one, without using the spreading mechanism of the Bitcoin network.

When a TRR node receives data, it will decrypt it using its private key. Then it transmits the remaining data to the next node. When the last TRR node is reached, it will release the transaction to the Bitcoin network. Every node knows its previous node and next node. Only the client and the last node know the content of the transaction but the last node does not know the IP address of the client.

The researchers analyze several possible de-anonymization attack strategies, including Bitcoin protocol sniffers, the Sybil attack, Sybil attack plus entry nodes, fake Bitcoin nodes and fake TRR nodes attack, and conclude that TRR can help clients gain strong anonymity.

"In addition, the experiments show that the performance of the TRR multi-layered encryption and decryption algorithm is satisfactory in practice and the growth rate of cipher text is very limited,” note the researchers in the conclusion.

The researchers acknowledge that the current TRR proposal is vulnerable to DoS attacks based on fake TRR requests, and state that further research to eliminate this weakness is ongoing.

But another weakness is that implementing TRR would require changes to the Bitcoin protocol. That is a serious weakness, because it seems evident that, in the privacy-as-bug climate that is developing around Bitcoin, there is just no way modifications to Bitcoin Core explicitly aimed at anonymity could ever be accepted.

Therefore, it might make more sense to consider implementing TRR in a privacy-enhanced sidechain. The modifications to Bitcoin Core required for implementing sidechains are justified by general considerations much more acceptable from a mainstream perspective. Sidechain Elements , the first experimental code base for sidechains released by Blockstream, includes confidential transactions, and a sidechain implementation of TRR could be a workable way to sneak privacy in.

The popular website Daily Dot covered the TRR white paper and noted that TRR first emerged in 2014 during the development of DarkNetCoin, a niche cryptocurrency focused on anonymity. Unfortunately the conclusion of the Daily Dot article, “Bitcoin did not respond to a request for comment about TRR,” reveals that the mainstream press still has basic things to learn about Bitcoin.
