Efficient Data Management for IPFS dApps
Vero Estrada-Galiñanes, Ahmad ElRouby, Léo Marc-André Theytaz
Inefficient data management has been the Achilles heel of blockchain-based decentralized applications (dApps). An off-chain storage layer, which lies between the application and th…
E-Vote Your Conscience: Perceptions of Coercion and Vote Buying, and the Usability of Fake Credentials in Online Voting
Louis-Henri Merino, Alaleh Azhir, Haoqian Zhang +4
Online voting is attractive for convenience and accessibility, but is more susceptible to voter coercion and vote buying than in-person voting. One mitigation is to give voters fak…
Tit-for-Token: Understanding Fairness when Forwarding Data by Incentivized Peers in Decentralized Storage Networks
Vahid Heidaripour Lakhani, Arman Babaei, Leander Jehl +2
Decentralized storage networks offer services with intriguing possibilities to reduce inequalities in an extremely centralized market. The challenge is to conceive incentives that…
Breaking Blockchain Rationality with Out-of-Band Collusion
Haoqian Zhang, Mahsa Bastankhah, Louis-Henri Merino +2
Blockchain systems often rely on rationality assumptions for their security, expecting that nodes are motivated to maximize their profits. These systems thus design their protocols…
Fair Incentivization of Bandwidth Sharing in Decentralized Storage Networks
Vahid Heidaripour Lakhani, Leander Jehl, Rinke Hendriksen +1
Peer-to-peer (p2p) networks are not independent of their peers, and the network efficiency depends on peers contributing resources. Because shared resources are not free, this cont…
F3B: A Low-Overhead Blockchain Architecture with Per-Transaction Front-Running Protection
Haoqian Zhang, Louis-Henri Merino, Ziyan Qu +3
Front-running attacks, which benefit from advanced knowledge of pending transactions, have proliferated in the blockchain space since the emergence of decentralized finance. Front-…
TRIP: Coercion-resistant Registration for E-Voting with Verifiability and Usability in Votegral
Louis-Henri Merino, Simone Colombo, Rene Reyes +9
Online voting is convenient and flexible, but amplifies the risks of voter coercion and vote buying. One promising mitigation strategy enables voters to give a coercer fake voting…
A Tree-based Construction for Verifiable Diplomas with Issuer Transparency
Rodrigo Q. Saramago, Leander Jehl, Hein Meling +1
Still to this day, academic credentials are primarily paper-based, and the process to verify the authenticity of such documents is costly, time-consuming, and prone to human error…
[Invited talk] Building a Disaster-resilient Storage Layer for Next Generation Networks: The Role of Redundancy
Vero Estrada-Galinanes, Racin Nygaard, Viktor Tron +3
Blockchain is the driving force behind a myriad of decentralized applications (dapps) that promise to transform the Internet. The next generation Internet, or web3, introduces a "u…
Alpha Entanglement Codes: Practical Erasure Codes to Archive Data in Unreliable Environments
Vero Estrada-Galiñanes, Ethan Miller, Pascal Felber +1
Data centres that use consumer-grade disks drives and distributed peer-to-peer systems are unreliable environments to archive data without enough redundancy. Most redundancy scheme…
Visions and Challenges in Managing and Preserving Data to Measure Quality of Life
Vero Estrada-Galinanes, Katarzyna Wac
Health-related data analysis plays an important role in self-knowledge, disease prevention, diagnosis, and quality of life assessment. With the advent of data-driven solutions, a m…
Limiting Lamport Exposure to Distant Failures in Globally-Managed Distributed Systems
Cristina Băsescu, Georgia Fragkouli, Enis Ceyhun Alp +7
Globalized computing infrastructures offer the convenience and elasticity of globally managed objects and services, but lack the resilience to distant failures that localized infra…
