I study the P2P layer of blockchain systems, how transactions propagate, where bandwidth gets wasted, and where security cracks open.

Now

May 2026

Reading the Geth and Lighthouse codebases in depth and running an Ethereum mainnet full node to collect real P2P trace data. Collaborating with STI to design and evaluate transaction-propagation strategies that reduce bandwidth waste from underpriced and already-known transactions.

Side-quests: probing mempool-layer security across Reth, Besu, and Nethermind.
