Lately I keep hearing people talk about block builders, bundles, it sounds like jargon… As a retail investor, I just need to know the basics: when you click swap/mint, it’s not immediately on the chain; in the meantime, someone packs a bunch of transactions into a block, and who goes first or last can sometimes determine whether you profit or get squeezed. Bundles are more like “submitting the whole set together,” making it harder for others to cut in line, but don’t expect it to guarantee you a win.

My understanding is just to think of it as a “backup”: you don’t need to master every parameter, just remember two or three safety points—don’t sign randomly, don’t chase overly hot trends, do important operations in batches, and leave some room as redundancy backup. Recently, the testnet incentives/points system has started to heat up again, with daily guesses about whether the mainnet will issue tokens… I just treat it as a lottery with random avatars, if I hit, it’s fate; if not, no big deal.
