Decentralization is resilience; that's why the internet even works at all. That was the entire point of it, in fact.

You don't keep a bazaar running with shadow knowledge. Either the important things are published or it doesn't run.

What is the shadow knowledge in this case?

Also curious, since the bazaar seems to be where one acquires shadow knowledge (grey market items, support structures for unregistered people etc.). See Chungking Mansions in Hong Kong for a practical example.
