Caliper-in-the-Loop: Black-Box Optimization for Hyperledger Fabric Performance Tuning
Yash Madhwal, Arseny Bolotnikov, Mark Prikhno +5
Hyperledger Fabric performance depends on many interacting configuration parameters, making manual tuning difficult. We study automated throughput tuning by treating benchmarking a…
Chain Reactions: How Nonce Collisions in ECDSA Compromise Polygon MEV Searchers
Yash Madhwal, Andrey Seoev, Raffaele Della Pietra +2
ECDSA signatures form the bedrock of blockchain transaction authentication, yet their security critically depends on proper nonce generation. We uncover a critical vulnerability in…
BugMagnifier: TON Transaction Simulator for Revealing Smart Contract Vulnerabilities
Yury Yanovich, Victoria Kovalevskaya, Maksim Egorov +6
The Open Network (TON) blockchain employs an asynchronous execution model that introduces unique security challenges for smart contracts. A primary concern is race conditions arisi…
From Paradigm Shift to Audit Rift: Empirical Analysis and Validation of Security Audit Methodologies for Asynchronous Smart Contract Systems
Yury Yanovich, Sergey Sobolev, Yash Madhwal +6
The Open Network (TON) is a high-performance blockchain platform designed for scalability and efficiency, leveraging an asynchronous execution model and a multi-layered architectur…
The Bidding Games: Reinforcement Learning for MEV Extraction on Polygon Blockchain
Andrei Seoev, Leonid Gremyachikh, Anastasiia Smirnova +8
In blockchain networks, the strategic ordering of transactions within blocks has emerged as a significant source of profit extraction, known as Maximal Extractable Value (MEV). The…
SwarmRaft: Leveraging Consensus for Robust Drone Swarm Coordination in GNSS-Degraded Environments
Kapel Dev, Yash Madhwal, Sofia Shevelo +2
Unmanned aerial vehicle (UAV) swarms are increasingly used in critical applications such as aerial mapping, environmental monitoring, and autonomous delivery. However, the reliabil…
