Recently, parallel processing and sharding have been quite the hot topics, but my first reaction in my mind is still: whether asset security and exit strategies are smooth or not.

Looking at routing separately is actually straightforward—crossing several layers, passing a few bridges, whether there’s room for rollback— the faster it is, the more you should ask: if something goes wrong, which route do you retreat along… otherwise, no matter how beautiful the performance, it’s just a show.

In the community, debates over privacy coins, mixing, and compliance boundaries are quite divisive.
I don’t take sides; anyway, those involved in transaction paths are all looking at the same thing: are you unknowingly pushing yourself into a path that’s harder to explain and harder to exit?

When I was a beginner, I thought “sharding = safer and more decentralized.”
Now I believe more: sharding/parallelism just spreads out complexity; security and exit strategies must be verified layer by layer.
