The 0-Block Opportunity

Why Same-Slot Execution is Everything.

In high-frequency on-chain trading, there are only two relevant outcomes: execution in the same block as the target transaction (0-block), or failure. Execution in the next block (N+1) is a guaranteed loss, as the arbitrage opportunity created by the initial trade has already been captured and exhausted by other MEV actors.

Back-running: This is the baseline strategy, where your transaction lands in the same 0-block as the insider's but executes after it. This allows you to capitalize on the immediate price and liquidity impact. It is the minimum standard for any serious MEV operation.

Front-running: This is the pinnacle of MEV. Your transaction executes in the same 0-block, but before the insider's. You don't just copy the trade—you capture a better execution price and maximize alpha. This requires not only speed, but tactical superiority in the Jito auction.

Our framework is architected to be source-agnostic. While Geyser provides a reliable baseline for our MVP, our entire alpha model is predicated on the low-latency, pre-finalization data that only Shredstream can provide. We believe that leveraging Shredstream for competitive, non-toxic MEV strategies is essential for market efficiency.
