# Data Sovereignty & Trust According to the DSSC description, trust is the foundation of any data space. Participants need to know who they are dealing with and must be able to exercise control over their own data. The building blocks in this pillar provide the technical capabilities that make this possible. The Data Sovereignty and Trust pillar consists of the following three building blocks. * [Identity and Attestation Management](https://blueprint.dssc.eu/?pane=technical\&technical=identity-attestation-management): establishing who participants are, and providing verifiable proofs of their attributes or roles. * [Trust Framework](https://blueprint.dssc.eu/?pane=technical\&technical=trust-framework): ensuring everyone follows the same baseline agreements and trust rules. * [Access and Usage Policies Enforcement](https://blueprint.dssc.eu/?pane=technical\&technical=access-usage-policies-enforcement): giving participants the tools to control who can use their data and under what conditions. Together, these form the backbone of a secure and reliable environment for data sharing. {% hint style="info" %} See the complete DSSC Description [here](https://blueprint.dssc.eu/?pane=technical). {% endhint %} --- # Agent Instructions: 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.
