All elements of the puzzle solution were disclosed in the open in this thread of bitcointalk forum before or on Jan 28th. It is:
0. alphabetcanary figuring out the pacemaker and the only route to read through the segments. Without the pacemaker the solution would not be possible (too many possibilities to order segments to do the search).
1. smracer suggesting to include the blob as the 4th stream of data (joint effort with zbyszek2) and I may say modestly that I liked and forced that idea too
2. crax0r figuring out that the pacemaker was just the artefact of the 0s on each second flame length xored by the key-string 011010
3. bug.lady, sblitz - observation, that the ISO-8859-1 and the Code Page 437 were full byte encodings and they were in essence the same encoding when restricted to digits and letters. Maybe it wasn't mentioned, but one (one who was looking for such things after crax0r's remark) could see that digits and letters had encodings starting with 0 as the first bit, and having every 8th bit equal 0 aligned nicely with the information that each flame coded 4 bits and every second flame height was 0 (after xoring).
4. zbyszek2 noted that the bit streams were correlated with each other - it kind of suggested that they should be the part of xor too.
What crax0r had wrong was that the xoring by the key-string 011010 was not restricted to length only, but it went in a kind of circle throughout all bit streams, but it could be figured out as per the observation 4 and moreover one was able to see that in that way the 0x1x1x pacemaker was preserved too.
Thus, the length stream (with the 0s) was bound to be the first bit of 4 for each flame and what was left was:
1. to figure out the coding (what value is 0 and what is 1) for remaining 3 data streams (2^3=8 possibilities here) and
2. the order of the remaining 3 streams (3!=6 possibilities),
which totalled to 6x8=48 possibilities. It was only a matter of time that it would be figured out by somebody on this forum.
What bugs me is that none of those people received a merit or a tip or any recognition. That it is claimed that an off comment by an off person was enough for a tip. That the tipped hinter seems to be close to coin artist - as per the convo. The convo which is strange. That the article had all the vocabulary wrong, as none on that forum ever used (narrow? wide?). That the solver "forgot" about 10% of the prize (and the fact that when the puzzle was created that 10% didn't exist, so it was easy to forget
). And that the money disappeared shortly after the solution was starting to be imminent as I tried to convince you, at least if you knew what would be the signs that somebody is on a right track.
I liked the puzzle and collaboration we had together here and it really bugs me that not only not everything is cristal clear, but also none of the people without whom the solution would not be possible received any recognition. But maybe I should just leave it be and move to some other endavours... I will now.
