It recovers the funded SegWit address bc1qrpn28qa82uyjg37dvsz3w7wpm3kpdea957nm9p, currently holding 800,000 sats.
The significant s bytes select nine emojis. Reading their Unicode bytes inside-out produces:
031dffd7ff0d400f0afcc3fdcefc0d400f0da10f3a390f77ff0d400f68fe0d080f
The 80-bit scalar h satisfying H = hG.
Therefore, not yet the final private key or WIF.
No evidence of a seed phrasethe puzzle appears to recover one ECDSA private key.
The remaining computational command is:
./rckangaroo -dp 16 -range 80 -start 0 \
-pubkey 031dffd7ff0d400f0afcc3fdcefc0d400f0da10f3a390f77ff0d400f68fe0d080f
The thread began on 5 June, and the funds were transferred to your 'target' address on 21 June. I would assume that this is not the target address from the challenge.
I was trying to solve it and created an emoji mapper that you can look up at
https://github.com/arturfromtheblock/emoji-mapping-tool.
You can also find the mapped emojis from this challenge there. Maybe someone can find something useful there.
I just found one thing: in this image, eight emojis are mirrored. You can look these up under the IDs in the published .csv file.
ID: 9, 56, 81, 134, 151, 162, 172 and 185.
