We study financial contagion in Compound V2, a decentralized lending protocol deployed on the Ethereum blockchain. We explain how to construct the balance sheets of Compound's liquidity pools and use our methodology to characterize the financial network. Our analysis reveals...

We use microeconomic theory to describe the inner workings of Constant Function Market Makers (CFMMs). We show that standard results from consumer theory apply in this new context, endowing us with powerful tools to characterize the optimal design of CFMMs...

We provide an overview of the academic literature on Automated Market Makers for Decentralized Exchanges. Our review puts an emphasis on contributions from researchers in economics and finance. We cover papers that study the optimal design of Automated Market Makers...

Tokenomics is an international forum for theory, design, analysis, implementation and applications of blockchains and smart contracts. The goal of the conference is to bring together economists, computer science researchers and practitioners working on blockchains in a unique program featuring...

This paper studies how transaction fees and seigniorage, equivalent to inflation in the cryptocurrency setting, affect miner incentives and trade congestion. Each cryptocurrency miner chooses how many new transactions to group into the next block of transactions that the miner...

In STARK-like zero -knowledge proofs, like those of the Starware company, the major algorithmic and mathematical breakthrough which enables such great performance in applications is the invention of very efficient "low degree test" of univariate polynomials. Our work enables to...

Tokenomics is an international forum for theory, design, analysis, implementation and applications of blockchains and smart contracts. The goal of the conference is to bring together economists, computer science researchers and practitioners working on blockchains in a unique program featuring...

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...

Multi-client functional encryption (MCFE) is an extension of functional encryption (FE) in which the decryption procedure involves ciphertexts from multiple parties. In this paper, we consider MCFE schemes supporting encryption labels, which allow the encryptor to limit the amount of...

In this paper, we present a multi-client quadratic functional encryption (MCQFE) scheme from function-hiding inner-product (FHIP). The main challenge in such construction is that all the clients require the access to the master secret key of the underlying FHIP scheme...
