Tokens and ICOs: A review of the Economic Literature

Tokens and ICOs: A review of the Economic Literature, with Andrea Canidio, Vincent Danos and Stefania Marcassa,
This article is a part of Principles of Blockchain Systems, Synthesis Lectures on Computer Science, 2021, Vol. 9, No. 2

About the book
This book is the first to present the state of the art and provide technical focus on the latest advances in the foundations of blockchain systems. It is a collaborative work between specialists in cryptography, distributed systems, formal languages, and economics, and addresses hot topics in blockchains from a theoretical perspective: cryptographic primitives, consensus, formalization of blockchain properties, game theory applied to blockchains, and economical issues. This book reflects the expertise of the various authors, and is intended to benefit researchers, students, and engineers who seek an understanding of the theoretical foundations of blockchains.

An Equilibrium Model of the Market for Bitcoin Mining

Published in the Journal of Economlical Economy
We propose a model that uses the exchange rate of Bitcoin against the US dollar to predict the computing power of Bitcoin’s network. We show that free entry places an upper bound on mining revenues and explain how it can be identified. Calibrating the model’s parameters allows us to accurately forecast the evolution of the network computing power over time. We find that a significant share of mining rewards was invested in mining equipment and that the seigniorage income of miners was limited.

Zero-Knowledge : trust and privacy on an industrial scale

To present the concept of zero-knowledge, this counter-intuitive technology and put it into perspective with uses and services, the “Blockchain and B2B Platforms” chair hosted at École Polytechnique and supported by CapGemini, NomadicLabs and Caisse des Dépôts, chose to interview two doctoral students, Sarah Bordage and Youssef El Housni, who are doing their research at the École Polytechnique’s computer science laboratory as part of the chair, and Anthony Simonet-Boulogne and Gilles Fedak, from the startup iExec, who see zero-knowledge as technology to be integrated into their offer.
