Whilst a few members have been arguing into a large void...others have been analyzing data, running tests, recording results, tweaking results, re-analyzing, re-doing everything lol.

Here is what I know, which is public data from my Puzzle Prefix channel...I have came up with good results on finding the next 48+ bit, matching h160 (leading).

....

(2^48 * 5) / 5400 = 260,624,978,435 average speed normally needed to find five 48+ prefixes no? (I mean unless you are one of the ones who say they could all be in a row, lol).
My actual speed = 264 CPU cores averaging 2.5ish MK/s = 660,000,000

Anywho, nothing really to write home about, but something to write about here.

Data used: Bram's data from 67 and my data from 64, 67, 68, and some of the current 69.
