# CAST

The solidified carbon production supply chain involves multiple organisations, from biomass providers to logistics companies, posing challenges in transparency and integrity assurance. The carbon capture supply chain requires verification to ensure process authenticity, but regulatory authorities struggle to monitor it due to its complexity. 

[Trust Trail (CAST)](https://www.deeptechcenter.org/post/introducing-trust-trail-a-platform-for-auditing-carbon-capture-processes) addresses this using blockchain and smart data models for transparency and reliability in the biomass supply chain. Within the CAST experiment, FIWARE context brokers ensure asset authenticity, while JadenX GmbH integrates [iSHARE components](https://dev.ishare.eu/) for secure data exchange among participants. This ensures that only authorised parties can access relevant information and offers production-grade components designed specifically for this CAST experiment. 

Trust Trail/CAST, powered by i4Trust, offers an innovative solution to monitoring and verification challenges faced in the carbon capture supply chain, supporting climate change mitigation and the [New Green Deal's objectives](https://commission.europa.eu/strategy-and-policy/priorities-2019-2024/european-green-deal_en).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://i4trust.ishare.eu/open-call-1/cast.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
