Slow and Steady: Preventing MEV with Verifiable Delays
Zeta Avarikioti, Dimitris Karakostas, Karl Kreder +1
Our work presents a defense mechanism against Maximal Extractable Value (MEV) opportunities in distributed ledgers. The mechanism relies on the idea of enforcing a verifiable delay…
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…
Majority is Not Required: A Rational Analysis of the Private Double-Spend Attack from a Sub-Majority Adversary

We study the incentives behind double-spend attacks on Nakamoto-style Proof-of-Work cryptocurrencies. In these systems, miners are allowed to choose which transactions to reference…
POEM: Proof of Entropy Minima
Karl Kreder, Shreekara Shastry
Nakamoto consensus has been incredibly influential in enabling robust blockchain systems, and one of its components is the so-called heaviest chain rule (HCR). Within this rule, th…
Scalable Multi-Chain Coordination via the Hierarchical Longest Chain Rule
Yanni Georghiades, Karl Kreder, Jonathan Downing +2
This paper introduces BlockReduce, a Proof-of-Work (PoW) based blockchain system which achieves high transaction throughput through a hierarchy of merged mined blockchains, each op…
