There is that this picture right here: It supposedly has a hidden message in it that ought to result in the personal key to an Ethereum pockets that has 1 Eth in it. A personal key for an ethereum pockets is a 64 hex character string. If anybody helps determine this puzzle out I don’t care to have the prize, I’ve simply spent many hours on this with no luck and want to know how you can clear up it. Here is what I do know to date: Running file on the picture yields this: PNG picture information, 1600 x 1105, 8-bit grey+alpha, non-interlaced. So it has no RGB values, simply grey and alpha. There are solely 434 pixels with an alpha worth lower than 255. I’m fairly certain that is the place the answer lies however after this I’ve no luck. I’ve tried numerous various things starting from taking part in with the bits for each the grey and alpha values for the pixels which have an alpha < 255. Converting them to ASCII and hex, reversing them, solely wanting in any case vital bit. At this level I’m at a loss. Any concepts? bobble 9,50044 gold badges3030 silver badges7777 bronze badges requested Apr 26, 2020 at 7:07 $endgroup$ 6 $begingroup$ The alpha values which might be lower than 255 truly appear to attract a cycle (white brief traces) across the ship. Perhaps the answer doesn’t lie in alpha, but it surely’s step one on the place to focus. hope it helps answered Apr 26, 2020 at 15:55 $endgroup$ 2 Your privateness By clicking “Accept all cookies”, you agree Stack Exchange can retailer cookies in your machine and disclose data in accordance with our Cookie Policy.
