If you read their blog, looks like they are using some kind of blockchain based carbon credits and offsetting 200%. That doesn’t sound corrupt. That sounds like a solution to combat the corruption in carbon credits if you ask me.

No, according to their privacy policy and T&C they use a blockchain to ensure "no connection between you and your billing data", which raises several red flags.

So you created an HN account just to post an extremely low-value, two-word comment. Are you also @techstuff123, the submitter? What is your relationship with nodevpn.com and greenvpn.com?

Having read the t&c now I am also interested in the authentication. I’ll log a ticket because I see no other mention of it.

"Thank you for your feedback regarding the mention of blockchain in the terms and condition in relation to our proprietary blockchain connection authentication. This information was in need of an update. We originally had our own blockchain which we were using to develop various ideas such as decentralised gateways and connection to them anonymously. However, we were unable to make it work in a way that added any value and as such it was subsequently dropped. Our solution currently makes no use of our own blockchain. However, our independent carbon credit provider uses their blockchain solution for tracking and eliminating corruption. I have now updated the t&c. If you would like more information on this or have any further questions, please do not hesitate to ask. Thanks again for helping us prepare for launch".
