Centralized Research
The DCI is engaged in collaborative research projects investigating the technical feasibility of CBDCs with several central banking authorities around the world. Current collaborators include the Federal Reserve Bank of Boston (the DCI’s collaborator in Project Hamilton), the Bank of Canada, and the Bank of England.
In addition, the DCI is engaged in collaborative techno-social research with Maiden Labs; this multi-disciplinary work, funded by the Gates Foundation, seeks to center global users in the design of digital currencies and to identify the technical and policy design choices most likely to increase financial inclusion and mitigate harm to the poor.
Many central banks are exploring the creation of a central bank digital currency (CBDC), a new form of central bank money which could be made available to the general public. Central banks, researchers, and policymakers have proposed various objectives including fostering financial inclusion, improving efficiency in payments, prompting innovation in financial services, maintaining financial stability, and promoting privacy. Because the CBDC research process is still in early stages, several technical design questions remain open for investigation, including whether or not a CBDC is even the right way to achieve these goals. The answers to these questions will have meaningful implications and consequences for what options are, or are not, available to policymakers.
The MIT DCI’s interest in CBDC research stems from a desire to ensure that neutral, responsible research is being done on this technology in order to inform policymakers of options. We don’t yet know if a CBDC can help improve our financial system, or how one might be best designed to do that, but we believe engaging in technical research is an important step in answering that question. Building and implementing helps us understand the challenges better, putting us in a unique position to help create designs that emphasize privacy, user agency, and financial equity.

Introduction
In a 2019 speech, Bank of England governor Mark Carney said that “Technology has the potential to disrupt the network externalities that prevent the incumbent global reserve currency from being displaced.” Certainly one of the most interesting places where technology is disrupting payments and finance is in cryptocurrencies. Cryptocurrencies have emerged from open source development communities in large part because electronic transaction systems are too expensive and they have not evolved fast enough to keep pace with the demand for retail online digital payments and more sophisticated types of financial transactions. The wide variety of experimentation in cryptocurrencies is causing technologists and central bankers to rethink the interface to money and explore a digital form which can be held by users and companies directly. This could lead to a financial system with a simplified institutional structure, capable of serving the public at a much lower cost. Though there has been much discussion about the policy design for central bank-issued digital currency (CBDC), there are important technical points missing from the conversation: CBDC should not be a direct copy of existing cryptocurrencies with exactly the same design and features but there are things we can learn from their emergence - the usefulness of programmability in money and the importance of preserving user privacy.
Cryptocurrency technology, in some instances, can provide an important feature: Anyone can participate and build applications with financial transactions to a standard, which creates a free-entry market that enables competition. These rules are set and maintained by users of the system, not by a coalition of companies or other large market participants. This is due in large part to the fact that many participate in observing, auditing, and validating the creation of money and the legitimacy of payments by observing a highly replicated audit trail of activities.
The cryptocurrency ecosystem should be viewed as a laboratory where developers are inventing different technologies, monetary policies, governance strategies, and reward systems which are competing. The space is still in its infancy, but make no mistake -- successful ideas from this area will eventually find their way into the more conservative world of fiat digital payments. Libra and other stablecoins are the latest prominent example of these ideas breaking through. There will be more.
This paper by DCI Reserach Scientist Robleh Ali sets out a structure for a digital fiat currency system. The primary benefit of the cellular structure is that it lowers barriers to entry for payments by using trustless intermediation between cells in the system. The larger purpose of this structure is to create an open foundation for a decentralized financial system in which competition can thrive but which cannot be captured by private interests.

The Bank of England announced an agreement to collaborate on a twelve-month Central Bank Digital Currency (CBDC) research project with MIT Digital Currency Initiative. The agreement supports and builds on DCI’s ongoing research into CBDC, while also contributing to the Bank of England’s wider research and exploration of central bank digital currencies. While no decision has been made on whether or not to introduce a CBDC in the UK, the work will investigate and experiment with potential CBDC technology designs and approaches, and evaluate key tradeoffs, opportunities, and risks. This type of research can help inform wider policy development by contributing important technical ideas and questions.
Today, the Bank of Canada announced an agreement to collaborate on a twelve-month CBDC research project with the MIT Digital Currency Initiative. The agreement supports and builds on the DCI’s ongoing research into CBDC, while also contributing to the Bank of Canada’s wider research agenda into digital currencies and fintech. The work will investigate and experiment with potential CBDC technology designs and approaches, and evaluate key tradeoffs, opportunities, and risks. While no decision has been made on whether or not to introduce a CBDC in Canada, this type of research can help inform wider policy development by contributing important technical ideas and questions.
Collaboration with Federal Reserve Bank of Boston yields progress in understanding how a digital currency might be developed in the future.
CAMBRIDGE, Mass. -- In collaboration with a team at the Federal Reserve Bank of Boston, MIT experts have begun designing and testing technical research through which further examination of a Central Bank Digital Currency (CBDC) can be performed in the U.S.
The effort, known as Project Hamilton, is in an exploratory phase, and the research is not intended as a pilot or for public deployment. Instead, the researchers have explored two different approaches that could be used to process transactions, and thus could indicate the technical feasibility of a potential CBDC model. In a process involving significant design flexibility, the MIT group tested factors such as the volume and speed of transactions, and the resilience of the systems in general, among other requirements for a viable digital currency.
DCI Director Neha Narula co-authored the piece, "Why Central Bank Digital Currencies?" published in the Federal Reserve Bank of New York's Liberty Street Economics
“In the past year, a number of central banks have stepped up work on central bank digital currencies (CBDCs – see map). For central banks, are CBDCs just a defensive reaction to private-sector innovations in money, or are they an opportunity for the monetary system? In this post, we consider several long-standing goals of central banks in their support and provision of retail payments, why and how central banks tackle these issues, and where CBDCs fit into the array of potential solutions.”

DCI will be collaborating with the Federal Reserve Bank of Boston to build a hypothetical digital currency. We are hiring a software engineer and there will also be opportunities for MIT UROPs and graduate researchers.
Proponents say payments with a digital dollar would be faster and easier. Opponents say it would be costly and inefficient.
The nature of money is changing, and central banks around the world are debating whether they need to change with it.
As electronic payments take off and private cryptocurrencies such as bitcoin seek to gain traction, governments are exploring whether to issue digital versions of their national currencies that could be used as a universal form of payment in the way physical cash is today. These conversations gained urgency for some last year when Facebook Inc.announced plans to launch a cryptocurrency called libra, sparking concern that one of the world’s most powerful technology firms could become even more powerful by operating its own digital money.
So far, few countries have implemented a digital currency, though China reportedly is close and several countries have done or plan tests. Considering the dollar’s key role in global markets, should the U.S. commit to such a project?
Proponents say a digital dollar managed on a single network would facilitate faster, cheaper payments and protect the Fed’s ability to conduct monetary policy in a changing world. Opponents say Fed-controlled digital currency would be costlier and less efficient than many expect, and it would harm privacy by giving government the ability to track all dollar spending.
Neha Narula, the director of the Digital Currency Initiative at the Massachusetts Institute of Technology’s Media Lab, makes the case for digitizing the U.S. dollar. Lawrence H. White, a professor of economics at George Mason University and a senior fellow of the Cato Institute’s Center for Monetary and Financial Alternatives, argues against.

Cash is gradually dying out. Will we ever have a digital alternative that offers the same mix of convenience and freedom?
by Mike Orcutt Jan 3, 2020
Think about the last time you used cash. How much did you spend? What did you buy, and from whom? Was it a one-time thing, or was it something you buy regularly?
Was it legal?
If you’d rather keep all that to yourself, you’re in luck. The person in the store (or on the street corner) may remember your face, but as long as you didn’t reveal any identifying information, there is nothing that links you to the transaction.
