>The implications of my comment were not simply that gamma is reduced to zero, but that the whole problem is thrown out the window because the entire pool would be banned from the network (blacklisted).
Ah, but even if detection worked perfectly (and did have a false positive rate of 0), who precisely do you blacklist? The Bitcoin wallet? It's trivial to generate more. The IP address? Which precise IP address? Even if you could locate the IP address of the submitting node accurately, a pool has many, and it's possible to get more.
Definitely was not implying the wallet, but more along the lines of an IP. Your raise a good point though, that IP addresses might not carry sufficient weight/reliability.
I must focus on other things now, but I want to thank you for bringing this problem to the attention of the bitcoin community, even if they have chosen to ignore it and pretend that it's a non-issue.
I look forward to reading your followup paper (if and when you publish it). I hope you'll have a good solution in it.
(My brain is tempted to consider some using sort of stronger identity system than IP addresses [like Namecoin], but I really don't like that. That could potentially cause far more severe problems, especially if done incorrectly. And it seems like a hack.)
