You guys think you are capable of judging John's capabilities but you don't even comprehend very basic Bitcoin 101 issues.

If the mining hash function is sufficiently broken, the cracker can rewrite the entire block chain with a greater difficulty (i.e. he can produce great difficulty with very little computing hardware). If the crack is public knowledge, then the longest rule means nothing and chaos results.

Chaining hashes doesn't always fix the risk, e.g. if one of the hashes in the chain has a very high level of collisions.


45/healthy and 51/chronically ill is indescribably different. 6 years ago I was still chasing girls and partying. Now I struggle with daily life. But don't feel sorry for me, I did it to myself with the life choices I made. And I am doing reasonably well with it since I discovered high dose curcumin extract. I think my problem is dysfunction in the pancreas, gall bladder, or colon (possibly cancer or auto immune disease thereabouts). Any way, I am getting some improvement, but it has taught me that life is for the moment. I don't think about living to 80. What ever I get, I will enjoy.

Main thing is I've stopped thinking like I was still young and my life is ahead of me. I started to think about decline and just making the most of remaining life. I think even without illness, this is a change in mental outlook that man goes through in his 50s. Perhaps it would be different if I was totally healthy and could still compete in athletics the way I love to. For example, last month I think I tore or strained the rotator cuff in my shoulder. Always painful to move my right arm.
