FairTraDEX: A Decentralised Exchange Preventing Value Extraction
Conor McMenamin, Vanesa Daza, Matthias Fitzi +1
We present FairTraDEX, a decentralized exchange (DEX) protocol based on frequent batch auctions (FBAs), which provides formal game-theoretic guarantees against extractable value. F…
Minotaur: Multi-Resource Blockchain Consensus
Matthias Fitzi, Xuechao Wang, Sreeram Kannan +4
Resource-based consensus is the backbone of permissionless distributed ledger systems. The security of such protocols relies fundamentally on the level of resources actively engage…
The non-locality of n noisy Popescu-Rohrlich boxes
Matthias Fitzi, Esther Hänggi, Valerio Scarani +1
We quantify the amount of non-locality contained in n noisy versions of so-called Popescu-Rohrlich boxes (PRBs), i.e., bipartite systems violating the CHSH Bell inequality maximall…

Matthias Fitzi, Nicolas Gisin, Ueli Maurer
We present a solution to an old and timely problem in distributed computing. Like Quantum Key Distribution (QKD), quantum channels make it possible to achieve taks classically impo…
