Maxim opened PR #1051 to remove the malachite production dependency from Rusty Kaspa, saying the LGPL-3.0 license was blocking consensus-core from becoming no_std compatible. [1] (PR #1051)
The PR adds an in-repository Lehmer modular inverse for the 3072-bit MuHash element, wires MuHash to use it, replaces the remaining production malachite log-base helper with a small standard-library helper, and keeps malachite only as a dev-time cross-check oracle. (PR #1051)
The Telegram thread gave a second benchmark signal beyond the PR body. On a Ryzen 9 7950X, Maxim reported the existing malachite path around 518 to 547 microseconds in one run, while the Lehmer path came in around 339 to 356 microseconds. [2] A second run improved both numbers, with malachite around 405 to 407 microseconds and Lehmer around 304 to 311 microseconds. [3]
This one should stay clearly marked as open work until merge. The reason it belongs in the draft anyway is that it combines a licensing cleanup, a no_std path, and a measurable MuHash performance improvement in the same reviewable PR. [1] (PR #1051)
