I would even argue that having multiple Haveno networks working together is unsafe. Because I would be able to create a Haveno network where the arbitrators and offer makers are colluding together and post those offers in the global Haveno network.

Then you from Reto would see my offers in my poisoned network and would be able to take them, and I could cam you. If that makes sense.

However with the current system, if you trust the Reto guys, then you just use Reto. If people stop trusting them, they will just spin up a new network.

The only downside I see to the current system is that if Reto goes under, then we are back to square one: Getting everyone onboard a new network once again from scratch.

Perhaps a future update of Haveno could add such "federated style" networks where you can see offers from different networks if it is done in a safe manner. Being able to ban or accept different networks to avoid poisoned ones.

Then if Reto goes under, not all is lost.
