Does the Transaction Speed of a Blockchain (E.g. Solana Vs. Ethereum) Impact the Feasibility of Front-Running?

Yes, higher transaction speed (lower block time) significantly impacts front-running feasibility. On very fast chains (like Solana), the window of opportunity for a bot to observe a transaction, calculate an arbitrage, and submit a higher-fee transaction before the block is finalized is extremely small, often measured in milliseconds.

This makes human-driven front-running impossible and even challenges bot-driven MEV, favoring systems with near-instantaneous finality.
