Material identity layer
MaterialDNA: a shared identity for circular materials.
MaterialDNA is the proposed identification layer for tracking materials across city loops. It is an early concept with no public pilots yet.
Scope & boundaries
In scope
Stable material identifiers, provenance metadata, and basic compliance signals.
Out of scope
Live asset tracking, financial settlement, or verified carbon accounting.
Status
Lab-demo concept only — no public pilots or deployments yet.
What we aim to enable
A common, verifiable identity for materials to support traceability, provenance, and matching across local loops.
Identity
Persistent IDs for batches and materials
Metadata
Attributes, quality, and compliance signals
Interoperability
Shared schema across city nodes
Data model snapshot
The v0.1.1 lab schema captures the minimum fields needed to identify and route materials across loops.
