I just went through the Komodo white paper on its delayed Proof of Work consensus mechanism (https://komodoplatform.com/whitepaper/). Has anyone else?

What do you think of this mechanism that notarizes transactions on to the bitcoin blockchain - providing stronger security (an attacker will have to bring both networks to succeed), but whose success also depends on the continous success of Bitcoin? What happens in the case of a the "split" bitcoin blockchain (Segwit, bitcoin Unlimited, etc)? Supanet (Komodo developers) appear to be staking a lot on this mechanism.

Thoughts?

Thanks!
