Nasrulin, B. (author), Ishmaev, G. (author), Decouchant, Jérémie (author), Pouwelse, J.A. (author)Manipulation of user transactions by miners in permissionless blockchain systems is a growing concern. This problem is a pervasive and systemic issue that incurs high costs for users of decentralised applications and is known as Miner Extractable Value (MEV). Furthermore, transaction manipulations create other issues such as congestion,...conference paper 2023

Nasrulin, B. (author), de Vos, M.A. (author), Ishmaev, G. (author), Pouwelse, J.A. (author)The growing number of implementations of blockchain systems stands in stark contrast with still limited research on a systematic comparison of performance characteristics of these solutions. Such research is crucial for evaluating fundamental trade-offs introduced by novel consensus protocols and their implementations. These performance...conference paper 2022

Nasrulin, B. (author), Ishmaev, G. (author), Pouwelse, J.A. (author)Decentralized reputation schemes present a promising area of experimentation in blockchain applications. These solutions aim to overcome the shortcomings of simple monetary incentive mechanisms of naive tokenomics. However, there is a significant research gap regarding the limitations and benefits of such solutions. We formulate these trade-offs...conference paper 2022

Nasrulin, B. (author), Pouwelse, J.A. (author)Decentralized systems offer alternatives to Big Tech. However, maintaining availability and correctness despite faults and manipulations in decentralized settings is challenging. In this paper, we introduce a collaborative model that is capable of exposing all observable lying, all cheating, and all faults, while only requiring merely...conference paper 2021
