Lately, I've been looking into blockchain builders, bundles, and these kinds of things, and I feel retail investors really don't need to force themselves to become "experts." To put it simply, knowing three points is enough: 1) The transaction you send out may not be confirmed on the chain in the order you want; someone might be packaging them; 2) Some packaging will bundle a series of transactions together (bundle) to reduce the chance of being front-run or sandwich-attacked, or simply to make arbitrage easier; 3) So don't blindly believe that "if I click it, it will definitely go first." Important operations should be done through reliable wallets/routes, and avoid randomly clicking on "faster and cheaper" buttons from unknown sources. As for deeper auction mechanisms or who is secretly coordinating with whom... that's the world of professional players.

By the way, I saw the NFT royalty debate flare up again, and it’s quite similar: everyone wants "fairness," but the secondary market always wants to pay less for liquidity, which ends up being enforced on-chain or bypassed, ultimately relying on who is better at bundling and routing... I’ve been staring at these data for so long that my eyes are a bit sore, and my neck is stiff. Anyway, I’m not going to look at it hard tonight.
