R3 Research provides compelling analysis and insight into the enterprise blockchain industry and specific practical applications across cash, payments, capital markets, trade finance, insurance and identity.
With the potential existence of multiple blockchains, interoperability across chains is a key concern. This paper explores various strategies for interoperability, and considers security and governance models in the financial services industry that may be impacted by increased interoperation. It also includes examples of interoperability across different financial use cases.
The European General Data Protection Regulation (GDPR) comes into effect on 25th May 2018. This paper assesses if and how the GDPR applies to public and private or consortium blockchains. The paper focuses on the crucial question of whether blockchains fall within the scope of GDPR, especially if personally identifiable information is processed. The paper proposes that this is most likely true and that with public blockchains the data is not simply anonymous. Finally, the paper describes the main obligations and requirements under the GDPR by which blockchain companies must abide.
Is a single global network or are multiple business networks the right structure for a distributed ledger ecosystem for trade finance? The answer will reduce uncertainty for market players and enable faster implementation of distributed ledger solutions. This paper considers the trade-offs between a single universal global network versus multiple business networks. For a universal global network to succeed, regulators would need to come to a consensus over legal and regulatory standards globally. In the specific context of Asia, multiple interoperable business networks more closely align with the existing diverse regulatory environment.
Maintaining data quality, reconciling trades, and exchanging assets between financial institutions using legacy information technology (IT) systems is expensive, slow and complex. Given the costs of integration and interoperability, this paper argues that distributed ledger technology product competition at the application level is more critical than competition at the platform level. By building an ecosystem on top of a platform, financial institutions can benefit from network effects and address historical IT complications.
Commercial and specialty insurance contracts and the resulting financial transactions between counterparties are both complex and costly to administer. Optimizing the operational processes across distribution networks and trading relationships remains a challenge for the industry. Operating inefficiencies cost the insurance sector and its clients billions of dollars annually. Blockchain-based platforms can reduce costs in the core Accounting and Settlement processes by coordinating shared processes and reducing complexity. Blockchain technology can also facilitate the final payment netting between counterparties. We consider design principles for blockchain platforms in the insurance sector and examine R3’s Corda architecture. This whitepaper is suitable for business readers who wish to understand some of the complexities in the Accounting and Settlement processes of this sector or technical architects who need to understand how particular platforms provide value within insurance.

Identity information has traditionally been captured on the individual level, and is limited to what is known of a person. This paper explains that the real value of identity comes from the relationships that can be examined and recorded between any number of persons, and not from information known of a single person.
The “Financial Identity Trilemma Syndrome” arises from the conflict between the three motivators of identity – compliance, security and customer service, and has the potential to shrink the customer base of banks. The paper further explains the importance of context on identity, pinpoints sources of unreliable identity data, and discusses the importance of a feedback loop that ensures the quality of identity information.
Describes different objectives and architectures for wholesale and retail domestic DLT solutions. Specifically, the paper compares JP Koning’s Fedcoin concept with the CAD-coin prototype of Project Jasper, a collaborative effort between six Canadian commercial banks, Bank of Canada, Payments Canada, and R3.
Rising regulatory and compliance costs have led financial institutions to seek solutions using new technologies. This paper considers the role DLT can play in financial compliance and discusses how R3’s Corda handles transaction reporting for OTC derivatives.

The problem of derisking is embedded in the lack of transparency in the correspondent banking ecosystem. DLT offers a potential solution – by embedding smart contracts into a correspondent banking utility, the process of due diligence could be faster, safer, and more transparent. The author explores how such a utility might work and its implications for both regulators and banks.
A hybrid approach can facilitate the adoption of production-quality DLT in capital markets. By applying DLT alongside more established technologies, DLT is more likely to meet the banking sector’s requirements on procurement, security and data privacy for capital markets use cases.
Before broad adoption is feasible, DLT platforms will require technical improvements in governance, interoperability, scalability, privacy, and usability. This paper explores the problems and suggests solutions to each.
Central clearing counterparties in derivatives markets play an important role in financial system resiliency. This paper explores the implications of DLT for risk reduction and efficiency improvements. It shows that DLT can both improve account management as well as act as a platform for interaction.

Central banks around the world have implemented Liquidity Savings Mechanisms (LSMs) in their large value settlement systems. This has been done to reduce the liquidity demands that come from interbank wholesale settlement. Today, central banks use a centralized queue to match offsetting payments. Central operators can neither assess the importance of payments, nor assess each commercial bank’s relative cost of liquidity provision. Decentralized LSMs would allow individual participants to make competitive netting proposals that reflect their current conditions in real time. This approach could address the problems of imperfect information, incomplete information, and prefunding hard limits. A decentralized system could reduce liquidity demands and potentially increase social welfare for all participants.
Multiple central banks have conducted experiments with blockchain for domestic settlement between commercial banks. While progress has been made on domestic interbank settlement, there is not a clear approach for cross-border settlement. Today, interbank payments between currency zones require correspondent banking relationships, Continuous Linked Settlement (CLS) accounts, or a combination of both. This paper discusses several options that involve distributed ledger technology (DLT). The first group of models would heavily involve central banks, the second group involve a trusted third party and a more passive role for central banks. The models are evaluated based on monetary supply implications, impact on liquidity management for commercial banks, settlement risk, credit risk, and complexity for central banks. This preliminary exploration intends to inform future work with international payments.

Given increasing physical cash in circulation in many areas, a cashless society is likely not achievable soon for most countries. However, there are certain countries, particularly the Nordics, where the rise of digital payments is accompanied by a decrease in physical cash. While consumer preferences may drive towards a near-cashless society in these countries, a fully cashless society is not possible without first addressing several obstacles. First, a credible technical solution would need to exist as a substitute for physical cash, given the risks to consumers of strictly holding money with defaultable private sector institutions. Second, laws and regulations regarding the use of physical cash would have to change. We discuss high-level designs for how a retail-facing central bank-issued digital currency (CBDC) could be built on R3’s Corda and evaluate legal changes in Norway.

Different use cases require different ledger constructs and consensus mechanisms. After broadly categorizing existing platforms by key characteristics, this paper assesses each category against the requirements of financial services use cases. The analysis concludes that the UTXO model provides the best fit for the financial services industry across many use cases.
From a data architecture standpoint, the design of smart contracts can on take various forms. This is in part because there is currently no formal guidance from regulators or industry bodies regarding the legal frameworks surrounding distributed ledger technology. This whitepaper sets out the questions on which guidance is needed.

Tim Swanson colorfully and comprehensively evaluates the COIN ETF and describes many of the idiosyncrasies of bitcoin as an asset. Tim discusses price manipulation risks, “The Winkdex,” facilitators for trade in the industry, out-of-band attacks, forks, and also discusses potential risks associated with unregulated exchanges and mining pools.
Clark Thompson and Chris Verhoef propose an experiment that intends to explore legacy code renewal strategies that leverage existing code bases at financial institutions, instead of attempting to develop smart contracts “from scratch.” Clark and Chris make the argument that reusing code assets will be a faster, cheaper and less risky path towards providing a rich functional catalog of smart contracts. Further, this approach would use code built under existing regulatory compliance schemes and, as a result, may be less subject to increased regulatory scrutiny than entirely new development.
Kevin Rutter compares retail foreign exchange (currency) markets with the growing but still nascent cryptocurrency markets. He evaluates the two markets across topics such as regulation, market structure, liquidity, leverage and short selling and derivatives markets. He also discusses the subtle ways that directional risk arises, putting exchanges and brokers (and as a result their customers) at financial risk, depending on whether they employ a principal or agency model.
Clark Thompson describes the potential for distributed ledger technology to provoke fundamental changes to current operating models in financial services. Clark describes the potential for cost reduction and avoidance, the benefits of sharing non-competitive business capabilities, a business capability model, risk reduction and risk avoidance, shared service utilities and externalization, and business change activities.
In this insurance series, Todd Bault first defines insurance quantumization and explains how fiat currency (a CBDC) on distributed ledgers will be “the killer app” for insurance. The second part describes how state management could be the disruption that finally cracks insurance, and that DLT is the “right” tool to facilitate that paradigm. Last, Todd concludes that Corda could be that future operating system for insurance in such a state-based world.
In this R3 Research brief, Kevin Rutter gives an introduction to commercial bank money and briefly discusses some advantages and disadvantages of the current credit creation system. Then he evaluates both cryptocurrencies and central bank-issued digital currencies (CBDC) regimes and their potential to alter the amount of commercial bank money. He argues that the introduction of a CBDC by a central bank would need to be mindful of the potential impact on credit and loaning activity. He states that the distribution of a CBDC could either be an expansionary or contractionary monetary policy decision and argues that initial implementations in advanced economies will likely aim be “neutral” by leaving the monetary supply as close to unchanged as possible.
Vitalik Buterin discusses the opportunities and challenges for private and consortium blockchains. He provides context for the development of Ethereum, touches on potential interactions between public and private blockchains, and discusses the topics of security, scalability, efficiency, privacy, and purity. Vitalik provides key recommendations on each of these themes.
Tim Swanson explains token crowdsales, a funding tool that companies use to generate capital by issuing and selling a native cryptocurrency. The paper discusses how offerings are commonly structured, the risks connected to the fundraising method, and provides examples of fraud. Many of the points made in the paper are also broadly applicable to cryptocurrencies.
JP Koning provides a concise summary of central bank retail and wholesale payments, international correspondent banking, and traditional remittance providers. He first explains the incumbent systems for each of these types of payments, then describes the emerging competition across the payments ecosystem, and concludes with the potential implications for banks. The paper is an accessible introduction to new payments technology across DLT and non-DLT solutions.
George Calle’s overview of initial coin offerings (ICOs) provides groundwork for how entrepreneurs, innovators and regulators can encourage legitimate ventures in the future. He begins by explaining how they are structured by focusing on new features and risks associated with these offerings. He also explores how ICOs may be evaluated by regulators and points out which laws are applicable.
