Reasoning Boosts Opinion Alignment in LLMs
Frédéric Berdoz, Yann Billeter, Yann Vonlanthen +1
Opinion modeling aims to capture individual or group political preferences, enabling applications such as digital democracies, where models could help shape fairer and more popular…
Majorum: Ebb-and-Flow Consensus with Dynamic Quorums
Francesco D'Amato, Roberto Saltini, Thanh-Hai Tran +2
Dynamic availability is the ability of a consensus protocol to remain live despite honest participants going offline and later rejoining. A well-known limitation is that dynamicall…
Multiple Sides of 36 Coins: Measuring Peer-to-Peer Infrastructure Across Cryptocurrencies
Lucianna Kiffer, Lioba Heimbach, Dennis Trautwein +2
Blockchain technologies underpin an expanding ecosystem of decentralized applications, financial systems, and infrastructure. However, the fundamental networking layer that sustain…
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…
Optimistic MEV in Ethereum Layer 2s: Why Blockspace Is Always in Demand
Ozan Solmaz, Lioba Heimbach, Yann Vonlanthen +1
Layer 2 rollups are rapidly absorbing DeFi activity, securing over $40 billion and accounting for nearly half of Ethereum's DEX volume by Q1 2025, yet their MEV dynamics remain und…
Recommender Systems for Democracy: Toward Adversarial Robustness in Voting Advice Applications
Frédéric Berdoz, Dustin Brunner, Yann Vonlanthen +1
Voting advice applications (VAAs) help millions of voters understand which political parties or candidates best align with their views. This paper explores the potential risks thes…
Kudzu: Fast and Simple High-Throughput BFT
Victor Shoup, Jakub Sliwinski, Yann Vonlanthen
We present Kudzu, a high-throughput atomic broadcast protocol with an integrated fast path. Our contribution is based on the combination of two lines of work. Firstly, our protocol…
Deanonymizing Ethereum Validators: The P2P Network Has a Privacy Issue
Lioba Heimbach, Yann Vonlanthen, Juan Villacis +2
Many blockchain networks aim to preserve the anonymity of validators in the peer-to-peer (P2P) network, ensuring that no adversary can link a validator's identifier to the IP addre…
SoK: Attacks on DAOs
Rainer Feichtinger, Robin Fritsch, Lioba Heimbach +2
Decentralized Autonomous Organizations (DAOs) are blockchain-based organizations that facilitate decentralized governance. Today, DAOs not only hold billions of dollars in their tr…
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…
Banyan: Fast Rotating Leader BFT
Yann Vonlanthen, Jakub Sliwinski, Massimo Albarello +1
This paper presents Banyan, the first rotating leader state machine replication (SMR) protocol that allows transactions to be confirmed in just a single round-trip time in the Byza…
The PoW Landscape in the Aftermath of The Merge
Lucianna Kiffer, Sophia Skorik, Yann Vonlanthen +1
On 15th September 2022, The Merge marked the Ethereum network's transition from computation-hardness-based consensus (proof-of-work) to a committee-based consensus mechanism (proof…
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…
The Hidden Shortcomings of (D)AOs -- An Empirical Study of On-Chain Governance
Rainer Feichtinger, Robin Fritsch, Yann Vonlanthen +1
Decentralized autonomous organizations (DAOs) are a recent innovation in organizational structures, which are already widely used in the blockchain ecosystem. We empirically study…
Consensus on Demand
Jakub Sliwinski, Yann Vonlanthen, Roger Wattenhofer
Digital money can be implemented efficiently by avoiding consensus. However, no-consensus implementations have drawbacks, as they cannot support smart contracts, and (even more fun…
