# Deducing the Necessity of DWNs

## Guiding Principles

  * Let developers be developers. Give them the freedom that they're accustomed to
* Keep things simple
* No Homer car

* Always keep reference application/service in mind


## DWN truths/goals
- Storage for user data to prevent vendor lock-in.
- Access awareness & control of user data by the owner.
- Standardizes mechanism for data read & write.
- Standardizes mechanism for DID-based auth.
- Native data encryption support, perhaps?!
