I think retail investors really don't need to research blockchain builders and bundling to the point of writing papers... Knowing about three things is enough: 1) The "quote" you see is not the final transaction price, especially during congestion, when a path is rerouted or slippage occurs, others can cut in front of or behind you; 2) Private/bundle essentially means inserting your trade into a more "certain" queue, reducing the chance of being front-run, but don't be overly superstitious—rules like builder/relay that you can't see can still change; 3) When dealing with particularly sensitive orders (large amounts, low liquidity, just opened markets), it's better to split orders, set limit prices, or wait instead of rushing in emotionally.

By the way, recently, the "attention mining" of social mining and fan tokens, I see it more as moving congestion from the chain to the information stream... Everyone fights for exposure, but ultimately only a few paths lead to transactions. Anyway, don’t mistake the hype for an advantage—just sleep on it.
