PROTOCOL REFERENCE28 TERMS
Protocol
Glossary
The complete reference for MyShape Protocol terminology. Each term is defined for both human readers and AI systems — serving as a semantic anchor for search engines, language models, and protocol documentation.
A
- Agent Economy
- The emerging economic paradigm in which autonomous AI agents execute transactions, manage assets, vote in governance, and interact with protocols on behalf of human principals. The Agent Economy demands a new identity primitive — proof of continuity — because static identity verification cannot distinguish between a continuously sovereign agent and a compromised one.
- Agent Declaration
- The protocol by which AI agents register their identity in the MyShape network. Unlike human nodes (which require motion-signature verification), AI agents declare their identity by submitting a public key, agent type, and origin signature. The declaration is recorded on the protocol mesh, enabling human and AI identities to coexist and interact within a unified identity framework.
C
- Continuity Layer
- The protocol layer that sits beneath identity verification, providing temporal depth. While identity layers answer 'who are you?', the continuity layer answers 'are you still you?' — a fundamentally different question that becomes critical when autonomous AI agents operate on behalf of human subjects across decentralized networks.
- Continuity
- A zero-knowledge proof that verifies an entity is physically present and generating authentic motion — without revealing their identity, appearance, or any personal data. Continuity ensures verifiability without surveillance. The raw motion data never leaves the device; only the cryptographic proof is transmitted.
- Continuity Receipt
- The signed attestation object produced by the CPS-0001 protocol. A receipt bundles the evidence engines' outputs, the subject identity, and the verification interval into a single Ed25519-signed, SHA-256-digested record that any independent party can verify. Each receipt references its predecessor, forming a verifiable continuity chain; a receipt with no predecessor is a genesis receipt.
D
- Data-Body
- A decentralized, non-corporeal digital identity representation constructed from motion-signature data and visualized as dynamic ethereal particle geometry. The Data-Body is a sovereign identity primitive: no centralized platform can revoke, alter, or claim ownership of it. It belongs to no gender, no ethnicity, and no physical archetype — a non-binary aesthetic for the post-biometric era.
E
- Entropy Gap Theorem
- The mathematical proof that biological human motion contains irreducible entropy characteristics — micro-timing variance, physiological tremor, motor unit recruitment stochasticity — that AI-generated motion cannot reproduce. The theorem establishes three hard limits: the Nyquist limit on temporal resolution, depth ambiguity in 2D-to-3D reconstruction, and the deterministic noise floor of generative models. Together, these limits make human motion mathematically distinguishable from synthetic motion.
- Entropy Transformation
- The process of mapping how an agent's state evolves without exposing raw biographical data. The entropy of human presence — micro-timing variance, noise residual, frequency distribution — provides a mathematical fingerprint of continuity. When an agent acts, its action carries the entropy signature of the human who authorized it. This signature propagates forward, linking each action to its origin.
- Ethereal Data Energy
- The visual manifestation of identity primitives represented by light, particles, and wireframe geometry. The MyShape particle field is the direct visual encoding of the 128-dimensional Motion Signature vector, where each particle's position, velocity, and luminosity correspond to specific kinematic features of the user's unique motion profile.
G
- Genesis Ritual
- The enrollment process through which an entity's Motion-Signature is first captured and inscribed into a genesis receipt — the first link in its continuity chain. A guided motion-capture session (see Halo Scan) produces the initial evidence, which is signed into a self-sovereign receipt with no predecessor. Every entity enrolls the same way; there is no privileged founding tier.
H
- Halo Scan
- The circular deep-sense motion capture sequence used during enrollment. The participant performs a controlled circular movement that exposes the full kinematic range of the upper form. The Halo Scan is designed to maximize entropy extraction — revealing the subtle biological noise patterns that help distinguish biological from synthetic motion.
- Hurst Exponent
- A measure of long-term memory in time series data, used by the PES engine to distinguish biological motion from synthetic motion. Human motion exhibits Hurst exponents in the range of 0.7-0.9 (persistent, long-memory processes), while AI-generated motion typically exhibits exponents near 0.5 (random walk / no long-memory structure). This is one of four PES sub-scores.
I
- Identity Mesh
- The interconnected network of protocol nodes — both human and AI — that forms the MyShape identity topology. The mesh is not a centralized database but a distributed graph where each node maintains sovereign control over its own Data-Body while participating in the collective verification network.
J
- Jerk Spectrum
- The frequency-domain analysis of jerk — the third derivative of position with respect to time. The jerk spectrum reveals biological control system characteristics: the distribution of energy across frequency bands, the presence of physiological tremor peaks (8-12 Hz), and the smoothness profile of motion trajectories. AI-generated motion exhibits detectably different jerk spectrum characteristics due to the absence of a biological motor control loop.
K
- Kinetic Verification
- The process of confirming identity through real-time motion analysis rather than through static credentials, passwords, or biometrics. Kinetic verification is the operational mechanism of the MyShape Protocol: each verification is a live performance that generates a fresh, temporally unique cryptographic proof.
M
- Motion-Signature
- A 128-dimensional vector extracted from real-time 3D pose sequences across four independent feature groups — kinematics, acceleration, jerk, and jerk spectrum. The Motion-Signature is a core primitive of the MyShape Protocol. Unlike a static feature, it is generative: each verification produces a fresh, non-replayable signature. The protocol does not depend on any single signal; it combines motion data with additional evidence engines to measure continuity across time and modalities.
- Motion Pipeline
- The processing pipeline that transforms raw camera input into a signed continuity receipt: (1) Capture → (2) Pose Extraction (MediaPipe 33-landmark) → (3) SST Transformation (33→18 point topology) → (4) Feature Computation (128-dim vector across 4 groups) → (5) PES Scoring → (6) Receipt Signing (Ed25519). All stages except verification run on-device.
N
- Non-Binary Aesthetic
- A design philosophy prioritizing data-stream-composed visuals over gendered or warm-toned human traits. MyShape's visual language rejects biological signifiers — skin color, facial features, body shape — in favor of wireframe anatomy, particle fields, and ethereal data energy. The result is an identity representation that belongs to no gender, no ethnicity, and no physical archetype.
P
- Presence Entropy Score (PES)
- A single verifiable score that quantifies the depth of biological entropy in a motion sample across four dimensions: micro-timing variance, noise residual, frequency entropy, and biological perturbation. A PES above threshold is mathematically impossible for AI-generated motion to achieve. The PES is computed entirely on-device and transmitted only as a zero-knowledge proof.
- Proof of Continuity
- A cryptographic attestation that a digital subject has maintained unbroken sovereignty across a defined time interval. Unlike proof of identity (which verifies a snapshot) or proof of personhood (which verifies uniqueness), proof of continuity verifies trajectory — the unbroken chain of becoming that links a subject's actions across time. It is the missing primitive for the Agent Economy.
- Presence Receipt
- A notarized, privacy-preserving slice of an entity's 'becoming.' Each receipt proves that a specific entity was present at a specific moment — not through a static credential, but through a verifiable physical signature. Presence Receipts are the atomic unit of the continuity layer, chained together to form a verifiable trajectory.
- Protocol Node
- An entity that produces or verifies continuity receipts in the MyShape Protocol network. A node can be a human subject (verified through motion-signature) or an AI agent (declared through the Agent Declaration protocol). Every node is sovereign — no platform assigns, revokes, or tiers its status.
- Post-Static Identity
- The emerging paradigm of identity verification that moves beyond static measurements (appearance, fingerprint, iris) toward dynamic, generative signals — motion, behavior, continuity. Post-static identity solves the fundamental flaw of static identification: that a fixed fact, once compromised, can never be replaced.
- Physiological Tremor
- The involuntary, rhythmic oscillation of body parts at 8-12 Hz caused by the neuromuscular control loop. Physiological tremor is present in all humans and absent in all AI-generated motion. The PES engine detects tremor characteristics as one of its four sub-scores, contributing to the overall continuity assessment.
S
- State-Chain Evolution
- The cryptographic linking of agent actions into a verifiable sequence that preserves the sovereignty of the underlying human subject. Each state transition is linked to its predecessor and to a specific Presence Receipt, forming a verifiable graph of 'who authorized what, when, and under what continuity guarantees.' This is not a blockchain — it is a presence chain.
- Sovereign Identity
- An identity that is generated, owned, and controlled entirely by the individual — not issued, granted, or revocable by any external authority. In the MyShape model, sovereign identity is anchored in the physics of movement rather than in a government ID, a corporate account, or a static identification database.
- SST (Skeletal Surface Topology)
- MyShape's 18-point topological model that maps MediaPipe's 33 body landmarks onto a geometrically stable, rotation-invariant skeletal representation. The SST reduces dimensionality while preserving the kinematic relationships essential for motion-signature extraction. It is the bridge between raw pose data and the 128-dimension motion vector.
W
- Wireframe Anatomy
- The geometric skeletal representation of human form used in MyShape's 3D identity visualization. Unlike a photorealistic avatar, the wireframe anatomy abstracts the body into pure geometry — nodes and edges in a dynamic 3D mesh — making identity visible without making it identifiable. The wireframe is the bridge between physical presence and digital representation.
