Recently, a bunch of people have been hyping up "modularization," saying that separating execution/data availability sounds pretty advanced. Others think: once this is implemented, ordinary users will immediately experience faster, cheaper, and safer transactions. In reality: you still click a few buttons for a swap, but behind the scenes, there are multiple layers of routing/bridges/middleware, any of which could cause issues and make you take the blame, especially when one signature grants "unlimited" permissions, which makes me really angry.

Moreover, right now, with privacy coins and mixing services, the compliance boundaries are being argued over as if they’re tearing apart. The more modular components there are, the more layers, and who can guarantee that the layer you’re using won’t suddenly be "compliance-ified" to the point that it directly blocks your transactions? Anyway, my current principle is very simple: the fewer signatures and authorizations, the better; avoid cross-chain if possible; and if something goes wrong, don’t blame the "blockchain being too new," blame yourself for acting too hastily. That’s all for now.
