<p>The benefit is a circular supply chain that goes beyond where it started and creates a closer connection between consumers and small growers. Processors, distributors, wholesalers and retailers can trace product provenance, creating market differentiation for sustainability, food security and quality. The hope is that by aligning incentives through an immersive customer experience that fosters informed purchasing decisions, we can empower an inclusive economy that encourages the actions to mitigate environmental impact and benefit people.</p>

<blockquote>
<p>This paper introduces a software architecture and implementation of a system based on design patterns from the field of self-sovereign identity. Scientists can issue signed credentials attesting to qualities of their data resources. Data contributions to ML models are recorded in a bill of materials (BOM), which is stored with the model as a verifiable credential. The BOM provides a traceable record of the supply chain for an AI system, which facilitates on-going scrutiny of the qualities of the contributing components.</p>
