Buy Bitcoin with 3D Secure Cards on Coinbase across Europe

We’re excited to announce support for buying bitcoin with 3D Secure-enabled credit and debit cards for users located in 26 countries in Europe. Last month we launched this feature for users located in the UK and Spain, and today we are extending it across Europe.

To get started, new users can sign up for an account and existing users can sign in, visit the payments method page and click “Add Credit / Debit Card”. Once you have added an eligible card, you will be able to select this payment method from the buy page to instantly purchase bitcoin in GBP or EUR. Since credit and debit cards will not require a customer to pre-fund their Coinbase account with a bank transfer, customers can now receive bitcoin much faster.

How do I know if my credit card supports 3D Secure?

3D Secure enables two-factor authentication for making purchases with a credit or debit card. 3D Secure is supported by most banks in Europe and the UK. You can contact your bank to determine if your card supports 3D Secure, or simply try adding it to your Coinbase account. You will get an error message if your card does not support 3D Secure.

SAFE Crossroads Podcast #18 SAFE Network School, Class One

In this Episode

We're happy to announce the opening of the Simpleton's School of the SAFE Network.

Since the SAFE Network is being built on a very different combination of fundamentals than has ever been used before and because it is so intricate, it's not possible to just wade in and get a full picture of it without some work. This is especially true because the network is still in development and so can't be used and learned by experience, either.

Therefore, the effort of this podcast up to this point has been to share and create interest in the SAFE Network, hopefully enough to inspire folks to take the time to dig in and study the subject more closely. That's been a fine approach, as far as it goes. Looking at various functions and news, and exploring the people of the network has been valuable, but after a while it's not enough.

Your host and others have been expending a lot of effort behind the scenes to improve the documentation and make it more accessible to everyone. That project is very far from satisfactorily complete, but good progress has been made.

I am also aware that there are a lot of people like myself who have the time to listen, but not to sit down and study. Also a lot of people learn best be audio input.

So here is what we are going to do: The SAFE Crossroads Podcast hereby opens its own SAFE Network School. We'll see where all it goes but, to start, the SAFE Network Wiki is a great basic overview of the network, with a lot of detail that will help. The other facility is the Simpleton himself, who is not a geek but has spent many, many hours interfacing data about the network directly, on the SAFE Network community forum, etc., and has accumulated insights which others should find useful.

Your host will be reading the wiki aloud, stopping to comment, cross-reference, look up glossary and other definitions, and generally working through the basics of the SAFE Network making them as accessible as possible. You'll get to see where the Simpleton has outstanding question, too, because I'll be open as we explore this together.

As we go forward, these School podcasts will not stand alone very well. Understanding of later ones will depend on earlier information and insights. But that's okay. It's the only way to go deeper.

I also see this approach making listener participation much more inviting. I look forward to feedback, questions and other input, and will do my best to integrate everything into a great experience for all.

We'll still be doing other types of podcasts as appropriate. But if you see the distinctive SAFE Network School logo, you'll know you're back in class.

So, let's see how this goes!

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.


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.


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.


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, 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, 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,” CEO John Bailon told Bitcoin Magazine.

An official with Satoshi Citadel, the parent company and investor of 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 platform or the platform, which is currently ranked among the top 300 most popular websites in the Philippines., a competitor of 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, because of its over-the-counter transactions for remittances and bills payments.

“ 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 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.

Vaultoro Seeks to Provide a Store of Value to the Underbanked World Using Gold and Bitcoin

Previously reported by Bitcoin Magazine , bitcoin and gold exchange Vaultoro has reached $1 million in gold trading volume, recording an average monthly trading growth rate of 91 percent and rapid increase of its user base. Following its milestone, Vaultoro plans to expand its team and services internationally, to become the “key ingredient for the 2.6 billon under-banked” individuals all around the globe.

Gold has been the international store of value for thousands of years. Unlike bitcoin or fiat money, gold has proved to be a stable universal currency with very low volatility. Based on the five-year gold chart taken from , the gold price in January 1, 2010 stood at around $1,100. At this time of writing, the price of gold is around $1,130, recording a mere $30 difference over the last five years.

Brothers Joshua and Philip Scigala developed Vaultoro to allow the underbanked population to escape the volatility of bitcoin and store their wealth in physical gold.

“We built Vaultoro so people anywhere in the world can hedge the bitcoin price volatility without going back to fiat but by instantly parking any value in gold. Gold gets its value from the markets and not by government dictate. It is also globally recognized as a store of value. It has lasted more than 3,000 years, whereas no paper fiat currency has lasted more than 200 without collapsing with terrible consequences for the holder,” Joshua Scigala told Bitcoin Magazine.

“We see Vaultoro being a key ingredient for the 2.5 billion underbanked in the world to be able to accept payment from all around the world with bitcoin, hold that value in assigned gold and then spend it within seconds using bitcoin again,” added Scigala.

Currently, Vaultoro stores all of its physical gold in a Swiss high-security vault, 100 percent insured against theft, fire and other eventualities. Unlike most of fiat-to-gold bitcoin exchanges, Vaultoro will deliver gold bars in physical form to their users at any time.

Vaultoro to Launch a Point of Sales App

Online merchants, especially in Latin America and Southeast Asia have fallen victim to the highly volatile nature of bitcoin and time and time again. Today, there are very few platforms that enable users to hedge the value of bitcoin to another asset.

With an aim to serve small and medium-sized bitcoin merchants in underbanked regions, Vaultoro plans to launch a point of sales application that “will allow merchants to choose their hedge, meaning a 50/50 split or a 10/90 split between bitcoin they get in and gold they hold. We are looking at possible partnerships with ATMs and mobile payment providers in these regions so they can hook up to our system via API and use gold and bitcoin directly or indirectly through us,” Scigala told Bitcoin Magazine.

“Lock-in Service”

A few bitcoin platforms such as Coinapult offer a bitcoin “lock-in” service that allows users to lock in the price of bitcoin to the price of another asset has been popular in the United States and Latin America. The Vaultoro team found the idea of a gold-to-bitcoin lock-in service interesting, but they believe that the lock-in feature would contradict the fundamental philosophy that wealth is backed by real physical assets.

“When someone trades into gold on Vaultoro they actually buy physical gold that is secured as their property in their name. The gold is held in what’s called a bailment contract meaning we secure someone else’s property (just like self-storage facilities hold your furniture). By offering to lock in someone’s bitcoin to a certain price we would be moving away from the fundamental philosophy that wealth is backed by real physical assets and not by a promise to lock a price and deliver on that,” said Scigala.

Instead, the Vaultoro team may look into diamonds or other physical assets that are even more stable than gold.


Currently, Vaultoro is considering a funding round to maintain its services and expand its team. The Vaultoro team is exploring a few options including crowdfunding campaigns and venture capital investments.

“Any other investment we would take on would not only be to raise money but also to gain expertise and knowledge by bringing onboard people that will help us grow our vision long term,” Scigala said. “A vision of open markets, a vision where we stop taking money from poor people in rich countries and giving it to rich people in poor countries, but rather give poor people in poor countries the tools to lift themselves out of poverty by enabling them to join a global market of goods and services through a bank and state independent monetary system we all know and love as Bitcoin.”

Bank of America Files Patent Application for Cryptocurrency-Mediated Wire Transfers

Bank of America (BoA) has filed a patent application titled “System and Method for Wire Transfers Using Cryptocurrency .” The application was filed in March and published on September 17 by the U.S. Patents and Trademarks Office.

The BoA filing describes an alternative to traditional wire transfers. The funds are first transferred to a cryptocurrency exchange, then converted to a cryptocurrency such as bitcoin, then sent to another exchange, and finally converted into another currency for the recipient. In other words, BoA wants to patent the concept of using a cryptocurrency as a transparent intermediate step for fiat currency transfers.

“A system includes a memory and a processor,” reads the abstract of the filing. “The processor is coupled to the memory and causes the system to receive an electronic request for a fund transfer and initiate a debit of a first amount of a first currency from a customer account. In response to determining using cryptocurrency is optimal, the processor can transfer the first amount of the first currency into an account associated with a first cryptocurrency exchange and initiate the purchase of a first quantity of a cryptocurrency from the first cryptocurrency exchange. The processor can transfer the first quantity of the cryptocurrency to a second cryptocurrency exchange and initiate the sale of the first quantity of the cryptocurrency at the second cryptocurrency exchange. The processor is further able to initiate the transfer of at least a portion of the resulting currency to a recipient.”

The system includes means to determine which transfer method – including cryptocurrency – is optimal in a given case. The decision strategy is based on time factors, price factors, exchange rates, fees charged by third parties, volatility and other relevant information. If using cryptocurrency is found to be optimal, the system includes means to determine which cryptocurrency or exchange should be used. For example, the system “may choose a particular cryptocurrency exchange because the cryptocurrency is priced favorably (e.g., cheap if purchasing, expensive if selling) or because the cryptocurrency exchange has a relationship with the enterprise.”

BoA claims that the system described in the patent application can reduce or eliminate disadvantages and problems associated with traditional wire transfers. The application notes that enterprises handle a large number of foreign wire transfer requests on a daily basis, and foreign transactions are becoming more common. The BoA filing is focused on making cross-border transactions faster: “It may be desirable to conduct a foreign wire transfer in less time than what current foreign wire transfer systems allow.”

The proposed BoA system can bypass traditional wire services, reduce the dependency on third party networks, and increase the reliability of fund transfers. Cryptocurrency-mediated transfers permit completing a foreign fund transfer in less time than traditional wire transfers, avoiding delays that may be caused by third party systems and services. Furthermore, transferring funds using a cryptocurrency reduces the need to transfer customer data to third-party systems, thus increasing control and security of customer data.

As usual with patents, the application tries to cover all possible technical implementations and use cases, and defines cryptocurrencies in a generic way. “A cryptocurrency is typically a peer-to-peer, decentralized, digital currency whose implementation relies on the principles of cryptography to validate transactions and generate the currency itself,” reads the filing. “Some examples of cryptocurrencies are: Bitcoin, Litecoin, Ripple, Peercoin, and Dogecoin. In some instances, a cryptocurrency, such as MintChip, may be backed by a government (e.g., Canada).”

Today, many banks and financial operators are warming up to the potential of digital currencies to reduce the time and cost of fund transfers, especially cross-border transfers. The BoA patent application tries to cover both existing and future cryptocurrencies, and all systems that use a cryptocurrency as a transparent intermediate step for fund transfers in fiat currencies. It seems likely that BoA is trying to claim ownership of cryptocurrency-mediated fund transfers, which might become commonplace soon. Of course, the move has been criticized by Bitcoin users, for example in this Bitcointalk discussion thread .
