Hi all,

The PERK team is happy to announce the release of PERK v2.1. This new version improves the design of the scheme by using a new modeling along with a new proof system which results in significantly shorter signatures. For instance, for NIST-1 security level, PERK v2.1 features sizes between 3.5 kB to 4.4 kB (reduced from 5.8 kB to 8.1 kB) while being faster than its previous version.
