Recently, someone has been arguing about which L2 has higher TPS and lower fees, also casually comparing subsidies... I, anyway, focus on bridges first, because bridges are where the excitement turns into accidents. Multi-signature sounds stable, but it’s actually just “a few people pressing confirm together,” when people panic, the group goes silent, or the key distribution is too concentrated, the risk quickly shifts from on-chain to individuals. Oracles are the same, if the price feed/message feed gets stuck for a moment, the bridge will start to doubt itself.

So my current stance on cross-chain is basically one sentence: if you can avoid bridges, don’t use them; if you must use a bridge, then wait for confirmation, don’t mind the delay. A little slower at most means missing out on “subsidies,” a little faster might directly send the principal away… Well, I’ll save a screenshot first, in case something happens, so I can compare how I was thinking at that time.
