I built something similar to this. It's a SSG and CMS that runs in the browser and publishes the raw Markdown and JSON metadata alongside the rendered HTML. Unlike this it doesn't use encryption as it only publishes public data.

As the source is available, other clients can easily parse the data so that content can be made available beyond the browser, such as text-only clients, indexing and discovery networks and custom readers. I've built a prototype terminal client to test this out.

Now that the editor is working, my plans are to add public follow/block/like lists to sites to add a lightweight social layer and to build an open indexer framework for content discovery.

It's not trying to be another social network protocol. It's first and foremost a publishing platform, designed to be as easy to use as something like Medium while still being simple, open and portable.

I'd really appreciate any feedback: https://www.sparktype.org.
