Strongpoint MPC cuts threshold SPHINCS+ signing from 85 minutes to under a second
csuwildcat · x · 2026-11-13
Project Eleven announced Strongpoint MPC, tackling a hard post-quantum cryptography problem: making hash-based signatures work with secure multi-party computation.
- Prior research estimated 85+ minutes just for the secure hash computations in threshold SPHINCS+ signing; the new approach brings threshold signing to under a second in certain configurations
- Launching with Ethereum support for leanSPHINCS and leanXMSS, with dealerless key generation and common threshold configurations
- Aimed at making post-quantum security practical for institutional custody
