Alright so I couldn't find any super new blockchains but I did find out about it Pi Network. So far they seem pretty pretty legit and $PI is currently around $39 but it's not tradable yet. They have an app on mobile where you can mine $PI and lockup the $PI and it seems pretty good. Their white paper is good. It was made by people from stanford. So i'm in it and mining on the app currently and will lockup literally all of my $PI. They also have referrals, and if you guys use my referral to get a wallet for $PI, my mining rate will go up. But other than that, it seems pretty legit and good secure chain.
