Recently, someone asked me again, "Should retail investors like blockchain builders and bundlers learn to write code?" Honestly, no need. You just need to know: the transaction you initiate may not go directly into a block; it could be bundled, front-run, or even sniped by someone. The protections you can take are only three things—don't set high slippage randomly, try to use protected routing/private sending (some wallets do this), and don't chase after on-chain "guaranteed profits." As for how builders auction or who colludes with whom... that's a graduate-level topic, and retail investors learning that might just doubt their lives and not increase their win rate.

By the way, regarding the recent debate over privacy coins/mixers and compliance boundaries, I just want to say: you think "privacy = security," but from a builder's perspective, it might just be "more attractive traffic." I treat complexity as an enemy; if I can simplify, I will—first, make sure I don't become free alpha.
