One-dimensional vs. Multi-dimensional Pricing in Blockchain Protocols
Aggelos Kiayias, Elias Koutsoupias, Giorgos Panagiotakos +1
Blockchain transactions consume diverse resources, foremost among them storage, but also computation, communication, and others. Efficiently charging for these resources is crucial…
Pool Formation in Oceanic Games: Shapley Value and Proportional Sharing
Aggelos Kiayias, Elias Koutsoupias, Evangelos Markakis +1
We study a game-theoretic model for pool formation in Proof of Stake blockchain protocols. In such systems, stakeholders can form pools as a means of obtaining regular rewards from…
Airdrop Games
Sotiris Georganas, Aggelos Kiayias, Paolo Penna
Launching a new blockchain system or application is frequently facilitated by a so called airdrop, where the system designer chooses a pre-existing set of potentially interested pa…
SoK: Measuring Blockchain Decentralization
Christina Ovezik, Dimitris Karakostas, Mary Milad +2
In the context of blockchain systems, the importance of decentralization is undermined by the lack of a widely accepted methodology to measure it. To address this gap, we set out a…
Balancing Participation and Decentralization in Proof-of-Stake Cryptocurrencies
Aggelos Kiayias, Elias Koutsoupias, Francisco Marmolejo-Cossio +1
Proof-of-stake blockchain protocols have emerged as a compelling paradigm for organizing distributed ledger systems. In proof-of-stake (PoS), a subset of stakeholders participate i…
Decentralized Reliability Estimation for Low Latency Mixnets
Claudia Diaz, Harry Halpin, Aggelos Kiayias
Mix networks (mixnets) enable anonymous packet-based communication via multi-hop routing. Measuring the reliability of mix nodes serving as intermediate hops in a way that is decen…
