We use nexus.io now, I own that domain. The OP hasn't been updated in many many years because KryptoKash tried to extort me to transfer it. He wanted a lot of money, nexusearth.com is our old domain we used, and again that was extorted by another member of the community that owned it (you guys know how crypto can be). When we didn't do what they wanted, they made it redirect to ethereum.org. Yes I am VidereLicet on Github, you can verify my commit history I've been developing this protocol for a long time. We made a new thread when KK tried to extort us, but the old thread still shows up on google as the one for Nexus. I'll go ahead and make a poll, happy to verify anything you guys need, I can make a record on nexus.io to prove I own that domain. You can see that is where our current website is.
Any other methods of verification please let me know, I've been around since 2014 and have developed a lot of serious technology to improve Bitcoin and the industry in general. It would be really nice to have our old thread back so I can keep this community up to date and keep a piece of our original history.
