The creator published this puzzle’s public key in 2019, which turns the search into a bounded discrete logarithm. Pollard’s kangaroo solves a 145-bit interval in about 2^72 group operations, far fewer than the 2^143 key tests a blind search would need. JeanLucPons’ CUDA Kangaroo is the standard tool; puzzles #130 and #135 were cracked this way by large GPU pools.
