Robust and Automated Reconfiguration of Byzantine Wide-Area Replication
Rowdy Chotkan, Bulat Nasrulin, Johan Pouwelse +1
Distributed systems handle adversarial nodes through redundancy, which imposes a significant performance overhead. In blockchain systems, Byzantine fault-tolerant state-machine rep…
StarveSpam: Mitigating Spam with Local Reputation in Permissionless Blockchains
Rowdy Chotkan, Bulat Nasrulin, Jérémie Decouchant +1
Spam poses a growing threat to blockchain networks. Adversaries can easily create multiple accounts to flood transaction pools, inflating fees and degrading service quality. Existi…
Taming Double-Spending in Offline Payments with Reputation-Weighted Loan Networks
Nektarios Evangelou, Rowdy Chotkan, Bulat Nasrulin +1
Blockchain solutions typically assume a synchronous network to ensure consistency and achieve consensus. In contrast, offline transaction systems aim to enable users to agree on an…
Sustainable Cooperation in Peer-To-Peer Networks
Bulat Nasrulin, Rowdy Chotkan, Johan Pouwelse
Traditionally, peer-to-peer systems have relied on altruism and reciprocity. Although incentive-based models have gained prominence in new-generation peer-to-peer systems, it is es…
LØ: An Accountable Mempool for MEV Resistance
Bulat Nasrulin, Georgy Ishmaev, Jérémie Decouchant +1
Possible manipulation of user transactions by miners in a permissionless blockchain systems is a growing concern. This problem is a pervasive and systemic issue, known as Miner Ext…
Gromit: Benchmarking the Performance and Scalability of Blockchain Systems
Bulat Nasrulin, Martijn De Vos, Georgy Ishmaev +1
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…
MeritRank: Sybil Tolerant Reputation for Merit-based Tokenomics
Bulat Nasrulin, Georgy Ishmaev, Johan Pouwelse
Decentralized reputation systems are emerging as promising mechanisms to enhance the effectiveness of token-based economies. Unlike traditional monetary incentives, these systems r…
YAC: BFT Consensus Algorithm for Blockchain
Fedor Muratov, Andrei Lebedev, Nikolai Iushkevich +2
Consensus in decentralized systems that asynchronously receive events and which are subject to Byzantine faults is a common problem with many real-life applications. Advances in de…
A Blockchain Database Application Platform
Muhammad Muzammal, Qiang Qu, Bulat Nasrulin +1
A blockchain is a decentralised linked data structure that is characterised by its inherent resistance to data modification, but it is deficient in search queries, primarily due to…
