TOR is a decentralized overlay network
Safing is a new onion network that you pay to use, so not as pure as Tor but looks promising https://safing.io/spn/
Anything that's not open source, really won't cut the mustard as a decentralized VPN
This deeper network place looks super sketchy. They sell your local bandwidth and pay you using their own weird cryptocurrency. That's going to just set your self up for lots of abuse. I would highly recommend anyone avoid it, especially non-technical people

All right reading the wiki summary, this place is closed source, getting venture funding, exploiting people's lack of knowledge of security, to resell bandwidth, but mostly to pump their own token. We've seen this time and time again with token based services, they pump the token, and they walk away. The promise of a utility token has not been borne out to be self sustaining yet. Everyone I see is backed by some investor pumping in money. Including sessions oxen token.
As far as their promise of a decentralized VPN goes it's a total lie. They're reselling people's bandwidth. Making them a proxy. But they're not doing any onion network. So peer-to-peer VPN if you like. There's a bunch of these different services out. There's nothing innovative about it. It's just oh you can get a retail IP address to do sketchy shit with, instead of the standard VPN provider data center IP address. The customers who want this are definitely not the people you want to be associated with
