This is very early work. I am trying to write a decentralized content management system (think Git, not Wordpress) in the Rust language.
Borrowing ideas from IPFS and Camlistore, my objective is to write software that can store and index objects, offering replication, sharing and search over multiple nodes.
Use cases:
- Store your backups in an efficient (de-duplicated) manner, and replicate them to different machines
- Index and tag your photos, allowing for efficient search by tag/date/location
- Ingest your Tweets and social media posts for posterity and easy search
- Wiki-like application with rich-text notes linking forward and back to images, files, emails, ...
- Persistent decentralized archive (archive.org mirror?)
- Backend for all kinds of applications (calendar, website, microblogging)
dhstore stores objects (structured, indexable documents) and blobs (bunch of bytes). An object is either a list or a dictionary with string keys, and cannot have nested containers. They can however reference other objects and blobs, allowing to store full JSON-like trees.
Everything is content-addressable (referenced by its hash) much like Git or IPFS. However, special objects called permanode allow for mutability: "claim" objects associate a permanode to a value, and can be authenticated via public-key cryptography.
For example, a permanode might be used to collect snapshots of some directory tree. Claims associate the roots of snapshots to the permanode, and can be searched by date.
