Re: Double spend with zero confirmations has been solved.
Btw, I think I have a solution of how to achieve zerotime. But I do it an entirely different way and my solution doesn't require all peers to see all transactions, so even if John fixes his, I've still got him beat (assuming my white paper comes together which is not finished yet).
I'd like to hear your idea in advance of your paper if you're willing to discuss it?
Well if you can offer peer review maybe that can be arranged. I will get back with you when I am prepared.
Btw, I tried to sleep and suddenly I solved the last remaining snag in my consensus design. I suddenly realized I indeed solved it. And yes mine will be fully proved in a white paper.
Just a few days ago, I solved the holy grail of anonymity:

It is all over for Bitcoin. Seriously. I will go silent. Next you hear from me will be via white papers.
Good luck.
