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…
SwarmSearch: Decentralized Search Engine with Self-Funding Economy
Marcel Gregoriadis, Rowdy Chotkan, Petru Neague +1
Centralized search engines control what we see, read, believe, and vote. Consequently, they raise concerns over information control, censorship, and bias. Decentralized search engi…
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…
Optimizing Streamlined Blockchain Consensus with Generalized Weighted Voting and Enhanced Leader Rotation
Diana Micloiu, Rowdy Chotkan, Jérémie Decouchant
Streamlined Byzantine Fault Tolerant (BFT) protocols, such as HotStuff [PODC'19], and weighted voting represent two possible strategies to improve consensus in the distributed syst…
Reliable Communication in Hybrid Authentication and Trust Models
Rowdy Chotkan, Bart Cox, Vincent Rahli +1
Reliable communication is a fundamental distributed communication abstraction that allows any two nodes of a network to communicate with each other. It is necessary for more powerf…
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…
Distributed Attestation Revocation in Self-Sovereign Identity
Rowdy Chotkan, Jérémie Decouchant, Johan Pouwelse
Self-Sovereign Identity (SSI) aspires to create a standardised identity layer for the Internet by placing citizens at the centre of their data, thereby weakening the grip of big te…
