+## Verifier
+
+Verifier-side requirements.
+
+### DPP Data Graph Collection
+
+Consumers must be presented all relevant product information with minimal effort.
+DPP Verifiers MUST follow all linked VCs to build the complete DPP graph.
+
+### Issuer Policies
+
+Consumers cannot be expected to make informed assertions about a global supply chain network.
+
+Collections of "which issers are relevant for which assertions" CAN be implemented by a DPP Verifier, turning a complex hypergraph analysis into a boolean good/bad indicator at the point of sale.
+
+Consumers may choose between policies, as per their preferences, for example "strict scope 3 carbon neutrality".

 # Specification
+
+Digital Product Passports enable consumers insights to the upstream supply chain of a product. These insights are built from a verifiable graph of product claims, asserted by relevant trust anchors along the supply chain.
+
+The motivation of Digital Product Passports is to promote and enable product repairs, reuse, and recycle, as well as enabling consumers a cryptographically verifiable basis on which to make purhase decisions.
+
+This spec describes a protocol for establishing the initial link from the product to the root-level DPP and from there contruct of the larger DPP graph.
