Weekly Dev Snapshot 📸 👇 Zond Fix for windows build Memory utilization optimization Added new REST API’s Updated logic that deals with the fork choice Refactoring Added more unit tests Fusion Signatures Update from Geometry Labs: NIST has informed Geometry Labs that they are only moving forward with many-times signature schemes at this time and will not include one-time signature schemes like Fusion in the current standardisation process. Although their limited scope is disappointing, it’s encouraging to hear from them that they thought Fusion was an interesting one-time signature approach and encouraged Geometry Labs to publish it for further peer-review.
If NIST decides to pursue one-time signature approaches in the future, Fusion signatures can always be resubmitted.
