I'll keep an eye on Nym, but I am pretty skeptical of any network that relies on a cryptocurrency scheme to operate, especially one with staking like Lokinet. Hypothetically it could work as an incentive structure, but the probabilistic nature of privacy schemes don't bode well, and I think the incentives for HODLing usually displace any actual interest in the network as a service.
Additionally, I have a hard time imagining Tor or I2P being displaced due to network effects, especially if it requires purchasing cryptocurrency, which is already pretty difficult.
