Understand personal data spaces

Start with the boundary between data and apps, then compare approaches.

This path offers a suggested order, not a mandatory course. Skip familiar questions or open any node directly from the map.

After reading, sketch an application you use. Locate its identities, credentials and data, and identify who decides access. Mark uncertainties as questions and return to the relevant node instead of using one term to explain the whole system.

Along this path

  1. How does a personal data space differ from an app database?

    Think about several applications using data within user-centered access boundaries.

  2. Why is Arc Space more than an identity feature?

    Identity and control relate to a space; applications also need usable data.

  3. Is MyData a principle, organization or product?

    Understand a human-centric direction without confusing it with a file protocol.

  4. How does Solid separate apps and data?

    Understand its boundary through Web resources and access control.

  5. Is IPFS a storage service or a set of protocols?

    IPFS provides content addressing, discovery and transfer mechanisms, rather than a single storage provider.

  6. What role does Filecoin play in storage?

    Distinguish providers, on-chain records, storage proofs and retrieval.

  7. How does Arweave differ from a personal data space?

    Separate a permanent-storage objective from everyday application data management.

  8. How do Arc Space, Solid, IPFS, Filecoin and Arweave compare?

    Compare control, access protocols, addressing and retention as distinct responsibilities.
