Background & Biography
Arvind Narayanan is the Bertram and Carole Siegel Professor of Computer Science at Princeton University and director of its Center for Information Technology Policy (CITP). His directorship began in July 2023. He earned his doctorate in computer science at the University of Texas at Austin and conducted postdoctoral research at Stanford University.
His work connects computer security, privacy and technology policy. Within digital finance, he has contributed directly to cryptocurrency education, blockchain-analysis methods and research on the privacy of online payments.
Notable Contributions
Narayanan co-authored Bitcoin and Cryptocurrency Technologies: A Comprehensive Introduction with Joseph Bonneau, Edward Felten, Andrew Miller and Steven Goldfeder. Published by Princeton University Press in 2016, the book explains Bitcoin’s operation, mining, security, anonymity and governance. Its accompanying teaching materials include lectures and programming assignments.
He is also a co-author of BlockSci, presented at the 2020 USENIX Security Symposium. The project introduced an open-source platform for analyzing blockchain data, using an in-memory analytical database. The paper applies the system to questions about cryptocurrency security, privacy and economics. This was collaborative work by a seven-author team, rather than a tool attributable to Narayanan alone.
In the 2018 paper When the cookie meets the blockchain, Narayanan, Steven Goldfeder, Harry Kalodner and Dillon Reisman studied how information collected by web trackers could connect cryptocurrency purchases to blockchain transactions and user identities. The work illustrates why payment privacy depends on the surrounding websites and user activity as well as the payment protocol.
Why Katharos.ai Follows Arvind Narayanan
Katharos.ai follows Narayanan for research and teaching that make cryptocurrency systems easier to examine critically. His work provides ways to test claims about anonymity, decentralization and the behavior of public ledgers.
His current personal research page describes a cryptocurrency-policy interest in addressing harms. Inclusion should therefore be understood as recognition of a researcher and critical policy voice, not as a claim that he promotes cryptocurrency adoption or endorses a token.
Areas to Follow
- Research on the privacy of cryptocurrency payments and transaction analysis. - Evidence about the security and economic assumptions of blockchain systems. - Teaching materials that explain how cryptocurrency protocols work. - Public-policy arguments that distinguish demonstrated uses from unsupported claims.
Reporting Scope
Coverage should preserve the dates and assumptions of each study. A finding about the sites and protocols examined in a historical paper should not be presented as a fresh measurement of every current payment service. Collaborative research should retain its coauthor attribution.
Katharos.ai’s interest is editorial. Inclusion does not imply a partnership, endorsement or advisory relationship with Narayanan, Princeton University or CITP.
Areas of Influence Category
Community, Media & Education is the primary category, reflecting his cryptocurrency textbook, teaching and public explanations. His research also informs technology-policy discussions. This profile remains unranked.
Current Position
Bertram and Carole Siegel Professor of Computer Science and Director of the Center for Information Technology Policy, Princeton University.
