Personal Knowledge Model (PKM) Slice Marketplace
Public concept page defining the PKM slice marketplace where users can package and publish granular slices of personal context under explicit consent and ownership controls.
TL;DR: The PKM Slice Marketplace is a protocol-governed platform surface where users can selectively publish bounded slices of their personal context. Slices are packaged and governed by PCHP consent receipts, keeping personal data sovereign and under explicit user control.

Overview
The Personal Knowledge Model (PKM) Slice Marketplace defines a consent-first framework for publishing granular, structured segments of user context—such as interest profiles, retail loyalty histories, or local telemetry preferences. Rather than exposing the user's entire World Model to third parties, the marketplace acts as a broker for sovereign, bounded "data slices."
Each slice is cryptographically signed, duration-bounded, and governed by a PCHP Consent Receipt Token (CRT) that specifies exactly who can access the data, for what purpose, and under what conditions.
Key Concepts
- Granular Slices: A slice is a narrow, typed subset of a user's Personal Knowledge Model. For example, a "grocery purchase history slice" contains only brand and item metadata, stripped of personally identifiable anchors.
- Sovereign Publishing: Users control which slices are active and can revoke permissions at any time. Slices are never broad-copied by third-party platforms; they are projected via secure cryptographic handshakes.
- Auditable Exchange: Every slice transaction produces a permanent, non-repudiable audit trail on the Hussh Transparency Log, ensuring users always know who has read their context and why.
