Byzantine Fault-Tolerant Post-Quantum Distributed Quorum Signatures
Quentin Kniep, Jakub Sliwinski, Roger Wattenhofer
Threshold, aggregate, and multi-signatures -- which we collectively call quorum signatures -- certify that a quorum of nodes endorsed a statement, with a certificate as small as a…
Mangrove: Fast and Parallelizable State Replication for Blockchains
Anton Paramonov, Yann Vonlanthen, Quentin Kniep +2
Mangrove is a novel scaling approach to building blockchains with parallel smart contract support. Unlike in monolithic blockchains, where a single consensus mechanism determines a…
Tyche: Collateral-Free Coalition-Resistant Multiparty Lotteries with Arbitrary Payouts
Quentin Kniep, Roger Wattenhofer
We propose Tyche, a family of protocols for performing practically (as well as asymptotically) efficient multiparty lotteries, resistant against aborts and majority coalitions. Our…
Quantifying Liveness and Safety of Avalanche's Snowball
Quentin Kniep, Maxime Laval, Jakub Sliwinski +1
This work examines the resilience properties of the Snowball and Avalanche protocols that underlie the popular Avalanche blockchain. We experimentally quantify the resilience of Sn…
Dissecting the EIP-2930 Optional Access Lists
Lioba Heimbach, Quentin Kniep, Yann Vonlanthen +2
Ethereum introduced Transaction Access Lists (TALs) in 2020 to optimize gas costs during transaction execution. In this work, we present a comprehensive analysis of TALs in Ethereu…
DeFi and NFTs Hinder Blockchain Scalability
Lioba Heimbach, Quentin Kniep, Yann Vonlanthen +1
Many classical blockchains are known to have an embarrassingly low transaction throughput, down to Bitcoin's notorious seven transactions per second limit.Various proposals and imp…
