@Saxophone3784 @NonPlayableClown @alex I don't think it's realistic to bolt on PoW functionality into the fediverse. I don't know if this would be an actual practical solution considering the nuances of why Josh's technique actually works (it requires an actual browser).

The solution is instances die and people migrate. It will happen over and over. You could argue that having very long running authoritative instances is bad for the decentralization of the network.
