PoW DVMs might be a way to do this possible.

We need POW to make disposable pubkeys (= no WoT score) not get filtered out.

PoW on a low-powered device can’t compete with e.g. a spam ASIC; the PoW cant be done in-device.

Imagine, a user wants a disposable identity, requests from a PoW DVM a pubkey with X number of bits of POW, pays for it and gets the tweak to get the pk. This could be done even without the DVM knowing the actual pk.
