I'm not convinced after reading this paragraph about Sybil attack defence. Cost favors large actors like state secret service and sponsored hacking. A free to buy into node network suggests with enough or cheaper early investment, you control the network.

Seems like it would only prevent small and ad-hoc actors. To me, even smells like it could be white-washing misleading.

I haven't looked into how the network is used specifically. If it's auth like vatlark suggested it would be bad. If it's purely delivery, I'm still wondering where blockchain comes into that, with the term suggesting persistency and agreement-based processes.
