Hey cool puzzle, just want to confirm I got this. I only saw it 20 minutes ago so thought I was probably late to the party or maybe no participants?

The Base58 address is: 1LsusxaEiGpTvWcXJA9ACRDKva8REjMokr   and it has been withdrawn. I didn’t expect it to be solved this quickly. apparently a hunter waiting for RetiredCode’s mini puzzle was on high alert. Congratulations to the winner.

PRIVATE KEY: 1BA27FB025BAF482573F6F34348EE6B14E9D8A3581C0B018DBECC642FA90D587 Let's break down the results: - Gap 1 (positions 10-19): BAF482573F - Gap 2 (positions 47-56): 8DBECC642F The diagnosis shows: - A total of 15 DB matches: 10 TT, 5 WW, 0 TW directly - 5 REJECTS (WW collisions with invalid g1/g2) - The solution was found in about 15 minutes. Verification: - Template: 1BA27FB025xxxxxxxxxx6F34348EE6B14E9D8A3581C0B01xxxxxxxxxxxxA90D587 - Found: 1BA27FB025BAF482573F6F34348EE6B14E9D8A3581C0B018DBECC642FA90D587 - g1 = BAF482573F (hex), g2 = 8DBECC642F (hex) — gap2 has the suffix A90D587 → hexes 8DBECC642F + A90D587 = positions 47-63 in the key ✓ - K = 5.191 (good, within the expected range of 1.5-11) - The program itself Verified: ec.MultiplyG(pk_found) == gPubKey ✓ Total for the modification: - Speed: ~7.5 GK/s (same as the original) - Solving time: ~15 min (K=5.19, range 40 per gap) - Jump table: 256 gap1 jumps (×2^176) + 256 gap2 jumps (×2^28) - Distance tracking: d1/d2 as separate i64s in the kernel - Collision: g1 = d1_tame - d1_wild, g2 = d2_tame - d2_wild

As we can see, kangaroos can be used easily for cases like this, see my post for details: https://bitcointalk.org/index.php?topic=5517607.msg66508168#msg66508168 Congrats to the winner!
