I asked him just that very question, and he said it was 300 milliseconds. He went on to say the common user wouldn't notice, but for developers, they'd have alot to say about it. He said this would be the NODES' answer to "proof" of work, and it would be another layer that would kill quantum "in the crib"..

I just got off the phone with my software engineer who also has a PHD in applied physics. He is autistic as they get, and still "normally" functions. I had told him to please solve the "Quantum" problem that Bitcoin will possibly have. I said, I'll get back to you in a few days. His only response was, "what time on Friday? ". I said noon. So, When I called him, He said " I have good news and bad news". This was uncharacteristic of him because he never displayed humor. I said, give me the bad news first. He said, ok, we will have to slow it down and heat it up ! I asked slow down what ? He said they'd have to slow block speeds down by ~10%, slow Node speeds down by ~25%, replace the chipsets on all nodes over time with an "ASIC style" chips, and it would help to increase the number of Nodes by 400%. He said that simple layer of an additional energy consuming proof of work protocol can, and will, eliminate the Quantum Compute threat for good. He said the new nodes could easily be a consumer level, "plug and play, inexpensive devices, that could also be used for any number of other tasks needing security. When I asked him, "what's the good news", he said, he is buying a load of bitcoin.
