The Sovereign Continuity Layer for the Simulation Age.

Identity tells you who someone claims to be. Continuity tells you they are still them. Motion-signature verification. Zero-knowledge presence. AI-native identity.

Overview

MyShape Protocol is the first continuity layer for digital identity — a protocol that verifies not just who you are, but that you are still you, continuously.

In an era where AI can generate faces, clone voices, and forge fingerprints, static identity verification is broken. MyShape introduces Proof of Continuity: a cryptographic primitive anchored in the irreducible entropy of human motion.

Camera → MediaPipe Pose (33-pt) → SST Topology (18-pt) → 4D PES Engine (128-dim Motion Vector) → ZK-SNARK Proof (~250 bytes) → Continuity Proof verified on-chain

All processing is on-device. Zero raw data leaves your device. ZK-Presence proves you are human without surveillance.

Core Concepts

Motion-Signature

A 128-dimensional vector extracted from real-time 3D pose sequences across four independent feature groups (kinematics, acceleration, jerk, jerk spectrum). AI cannot simulate this due to three hard mathematical limits: the Nyquist limit, depth ambiguity, and the entropy gap theorem.

Presence Entropy Score (PES)

A 0-100 score quantifying the biological entropy in motion across four dimensions: micro-timing variance, noise residual, frequency entropy, and biological perturbation. Human motion consistently scores 70+. AI-generated motion scores below 20.

Proof of Continuity

A cryptographic attestation that a digital subject has maintained unbroken sovereignty across time. Three primitives: Presence Receipts → Entropy Transformation → State-Chain Evolution.

ZK-Presence

A zero-knowledge proof (~250 bytes, .supabase.co NEXT_PUBLIC_SUPABASE_ANON_KEY=sb_publishable_... SUPABASE_SERVICE_ROLE_KEY=sb_secret_... RESEND_API_KEY=re_...

Brand Compliance

All code, copy, metadata follows de-corporealized identity language:

✅ Use ❌ Never Use

entity, agent, silhouette gendered identifiers

wireframe anatomy, data-outline biological signifiers

ethereal data energy, particle body aesthetic judgments

motion-signature, kinetic verification profile images, avatars

non-binary aesthetic, non-corporeal biometric identification

Pre-commit hooks enforce these rules automatically.
