Recently, I keep seeing people complain about MEV and unfair ordering, saying that miners/validators are taking an extra cut, and I’ve also become a bit anxious. To put it simply, retail investors don’t actually need to study “block builders, bundles” as academic papers: you just need to know that some transactions are packaged together and put on the chain as a bunch, and the order might not be decided at the moment you click confirm; there are people who cheat to抢优先级 (抢优先级 means “抢先” or “抢先交易” —抢先 means “抢先” or “抢先交易” — “front-run” or “priority抢先”). For someone like me who’s afraid of liquidation, there are two sufficient conclusions: don’t chase prices aggressively when liquidity is thin, and don’t use operations that have large slippage and love to argue on-chain about transactions. If I want to go a bit further, just remember “the quote you see might not be your turn to execute,” and first control your position and emotional curve… As for everything else, it’s okay to wait until you’re hurt enough to review it again someday.
