Decentralizing trust, empowering individuals, and disrupting power structures with cryptographic peer-to-peer exchange

As innovation in electronic payments accelerates, privacy considerations are becoming ever more important. While the generation and use of data is an intrinsic part of electronic payments and can benefit consumers and businesses, it may also present privacy concerns, particularly if there are not sufficient safeguards.

On April 16, Dr. Joachim Nagel, President of the Deutsche Bundesbank, the central bank of Germany, visited the MIT Media Lab. There, he announced this new collaboration between the Bundesbank and the DCI for central bank digital currency design research.

In October, former central banker Chris Calabia of MIT’s Digital Currency Initiative (MIT DCI) gave a talk at The Institute of International & European Affairs titled “Towards a Central Bank Digital Currency? One View from the United States.”

In this, the second of the IIEA’s mini-series of webinars on the subject of central bank digital currencies (CBDCs), Chris Calabia, Head of CBDC Programs at the Massachusetts Institute of Technology (MIT) Digital Currency Initiative, shares recent research on the opportunities and challenges presented by the potential introduction of a CBDC like a ‘digital dollar’. Mr. Calabia addresses practical and policy questions that this digital asset could raise for our economies and societies, including whether CBDCs could promote greater financial inclusion and how to safeguard privacy while mitigating other risks like fraud and money laundering.

MIT DCI research scientist Daniel Aronoff shared his work on US Treasury repo markets on two occasions this fall. He spoke on the “Repo on chain and collateral mobilization” panel at the 2023 Rates & Repo North America, and participated in the NBER Market Design Working Group Meeting. You can find information about his ongoing research on this topic here, and watch a video of the panel below.

In November, MIT Digital Currency Initiative research scientist Daniel Aronoff participated in a panel discussion along with Ed Golding, Executive Director of the MIT Golub Center for Finance, on fintech and the digitization of finance at the MIT Research and Development Conference. The lively conversation touched on many topics relevant to DCI’s work, including safeguarding privacy in central bank digital currencies, decentralizing repo markets through smart contracts, and the future of cash.

On April 27, DCI director Neha Narula spoke at Consensus 2023 on private and public money and the role of blockchain technology in future digital payment systems.

James Lovejoy, of the Federal Reserve Bank of Boston, presented "Hamilton: A High-Performance Transaction Processor for Central Bank Digital Currencies" at NSDI '23. This paper was co-authored by Madars Virza, Cory Fields, and Neha Narula of the DCI and James Lovejoy, Kevin Karwaski, and Anders Brownworth of the FRBB, and it proposes the Hamilton transaction processor, one of the primary results of this collaboration.
