Enhancing Ethereum P2P Network Security through Fuzzing | Devcon SEA

Thu, Oct 2, 2025, 12:00 AM

Security is a big deal for Ethereum's p2p network. We think fuzzing is a great way to make it more secure. We developed a time-series-based fuzz testing tool for the Ethereum network layer. In this tool, we integrated mutation mechanisms and seed selection algorithms, and introduced a new time-series feedback model. Using this tool, we can spot and fix existing vulnerabilities while also spotting new risks.
