A Blockchain Based VPN. Now this is a damned interesting idea.
https://www.orchid.com/ Now this is an interesting idea -- granted one that probably requires additional evolution -- but the core concept hits at the problem I have had with every VPN that I have ever used -- how do I know that my VPN company isn't collecting and abusing the data that I send through their networks? Orchid VPN seeks to provide an answer to this question through the creation of a decentralized virtual private network -- allowing users to buy bandwidth from a global pool of service providers.
I heard about this network at CNET and you can read the article here
This approach seems to make VPNs a bit more like the TOR (The Onion Router) network. I'll post a good tutorial on TOR soon.
