Jacob D. Leshno, Chicago Booth School of Business - On the Viability of Open-Source Financial Rails: The Economic Security of Permissionless Consensus
When: Friday (Sep 19), 11:00-noon
Where: AKW200, Arthur K. Watson Hall, 51 Prospect St, New Haven, CT 06511, US
Abstract:Bitcoin
demonstrated the possibility of a financial ledger that operates
without the need for a trusted central authority. However, concerns
persist regarding its security and considerable energy consumption. We
assess the consensus protocols that underpin Bitcoin's functionality,
questioning whether they can ensure economically meaningful security
while maintaining a permissionless design that allows free entry of
operators. We answer this affirmatively by constructing a protocol that
guarantees economic security and preserves Bitcoin's permissionless
design. This protocol's security does not depend on monetary payments to
miners or immense electricity consumption, which our analysis suggests
are ineffective. Our framework integrates economic theory with
distributed systems theory, and formalizes the role of the protocol's
user community.
Bio:Jacob
studies market design, using theoretical tools to explore market
structures and design effective market rules. His research has been
recognized by the ACM SIGecom Test of Time Award and the INFORMS
Frederick W. Lanchester Prize. A significant portion of his work focuses
on matching markets, such as college admissions and the NRMP medical
residency match. His research includes using tractable cutoff
characterizations to clarify the structure of these markets and support
empirical estimation and design optimization. He also work on
cryptocurrencies, Web3, and blockchain technology. This technology
allows for a new form of market design in the form of platforms whose
rules are given by open-source computer code. His work explores the
potential and limitations of these open systems. He taught a PhD class
on the economics of distributed systems to bridge computer science
theory and economic theory.
