... One of the fundamental design errors for PoW mining has been the simultaneity requirement that leads to orphans. It is essentially an aliasing error on consensus. That will give you a big hint as to what the big breakthrough in my design solution is. And it turns out I can retrofit it to a non-PoW algorithm that doesn't suffer from PoS's weaknesses...

We can't escape from proof-of-work (PoW) and maintain decentralized consensus. Period.
I missed your progress on this, and a cursory search didn't find much. Was there headway, or was your latter declaration final after testing different concepts?
I am preparing to go silent. Any questions or comments?
Yes, when? Still waiting
