Calyx: Privacy-Preserving Multi-Token Optimistic-Rollup Protocol
Dominik Apel, Zeta Avarikioti, Matteo Maffei +1
Rollup protocols have recently received significant attention as a promising class of Layer 2 (L2) scalability solutions. By utilizing the Layer 1 (L1) blockchain solely as a bulle…
A Composable Game-Theoretic Framework for Blockchains
Zeta Avarikioti, Georg Fuchsbauer, Pim Keer +2
Blockchains rely on economic incentives to ensure secure and decentralised operation, making incentive compatibility a core design concern. However, protocols are rarely deployed i…
A Security Framework for General Blockchain Layer 2 Protocols
Zeta Avarikioti, Matteo Maffei, Yuheng Wang
Layer 2 (L2) protocols, payment channels, sidechains, and rollups, are central to blockchain scalability, enabling off-chain execution while preserving on-chain security. Despite g…
CoBRA: A Universal Strategyproof Confirmation Protocol for Quorum-based Proof-of-Stake Blockchains
Zeta Avarikioti, Eleftherios Kokoris Kogias, Ray Neiheiser +1
The security of many Proof-of-Stake (PoS) payment systems relies on quorum-based State Machine Replication (SMR) protocols. While classical analyses assume purely Byzantine faults,…
Optimal Reward Allocation via Proportional Splitting
Lukas Aumayr, Zeta Avarikioti, Dimitris Karakostas +2
Following the publication of Bitcoin's arguably most famous attack, selfish mining, various works have introduced mechanisms to enhance blockchain systems' game-theoretic resilienc…
Thunderdome: Timelock-Free Rationally-Secure Virtual Channels
Zeta Avarikioti, Yuheng Wang, Yuyi Wang
Payment channel networks (PCNs) offer a promising solution to address the limited transaction throughput of deployed blockchains. However, several attacks have recently been propos…
