MotionPrint – Privacy-First Protocol for 3D Motion Provenance

Summary: MotionPrint is a cryptographic protocol that uses Ed25519 signatures to verify the authenticity of 3D animations without uploading files. It operates locally in-browser or Blender, supporting glTF/GLB and BVH formats with fast, non-destructive processing.

What it does

MotionPrint signs 3D motion data locally using Ed25519 and WebAssembly, ensuring asset provenance without external uploads. It integrates with Blender and supports common 3D animation formats.

Who it's for

It is designed for 3D artists and creators seeking secure, trustless proof of authorship for their animations.

Why it matters

It addresses the need for independent verification of 3D creative ownership, preventing unauthorized removal or misuse of work.
