While we're waiting for RTX 5090 here's some really fast jumper for 64-bit CPUs.

I’m working on a Pollard’s Kangaroo implementation for secp256k1 and I’d love to achieve high performance for point arithmetic on CPU (in particular, large-scale multiplications of G and other points). Could you please share or publish your HPC‐optimized code and techniques? I’m especially interested in any optimized field/group operations, batched inversions, or other CPU‐level optimizations you’ve used to speed up these computations.

Why would you need large-scale multiplications of G, it's only needed to create the initial kangaroos. Anyway, you can use libsecp256k1 for that or extract relevant code from it, like I did. You can also optimize further the code I posted, like keeping Y2 always in negated form and caching the jump index. More than that IDK if there's more to do on a CPU, as the batched inversion I presented is already the "parallel" tree-based version (hence the tradeoff with double-size tree storage, to avoid race conditions and r/w overlaps), not the "serial" version. Also, a RTX 4090 is 1000 times faster than a single-core high-end CPU, so my optimizations start there, not for CPU code.

First finding way was brute force by brain flayer
Where lot of option including stdin also available
Later just simple brute force were bitcrack, where upon multi request for stride option, and all other request for updation for some other function denied
3rd telariust bring kangaroo CPU version by given idea to him by her 9 years old daughter, , and he created first gpu version too
Later Jean luc optimisation for better gpu base kangaroo
Long time No next level working seems, no new idea, new level programing, new logics etc
Hope 2025 will change
But again Question
After pubkey of 135... 160 pickup, what will be next
Broken wif ?
Or
......
