I'd want to know if some of these competing technologies has more chance to survive. It seems they are thought to solve a similar problem by different manners and I'd want to stick to the most compatible/used/foreesable to win. It seems it's CT but I'm not sure. Thanks!

1$\begingroup$ also CAA is useful if you are NOT using https, it can prevent a CA for issuing a fake cert for your domain to an attacker $\endgroup$ – Richie Frame Nov 20 '19 at 3:28
