I was just chatting with a friend about block building and bundles. He asked me whether retail traders need to understand these things to really get good at it. My view is: knowing that it exists is enough; you don’t need to go too deep. Think about it—at bottom, a bundle is essentially packing a set of transactions and putting them together for miners, along with tactics like front-running, sandwiching, and Clean Up. Retail traders can’t do this themselves; the costs are too high, and the technical threshold is also high. But knowing it exists has one benefit: at least you can understand why on-chain transactions sometimes get stuck for no obvious reason, or why slippage suddenly blows up. It’s like driving a car—you don’t necessarily have to dig up the potholes yourself, but you should be able to steer around them.

Lately, I’ve been watching the whole drama around NFT royalties. It’s been pretty heated. Some people think creators should have certain rights, while others complain the protocol strips off too much. Personally, I think this is a bit like the role of block builders—when there are more middlemen, liquidity ends up getting awkward. But who can say for sure? The market always self-corrects; as long as retail can last through it.

Forget it—I’m too lazy to sort out the fine details. Let’s leave it at that.
