Felfele Social Protocol Draft

Felfele Social Protocol

In this article we will describe a social protocol on the Ethereum Swarm decentralized cloud service. Our goal is to make the protocol comprehensive and practical so that it covers all the basic functionality, although due to the richness of social applications it does not thrive to be complete. This is not (yet) a specification of a standard, but rather a result of research that hopefully inspires others to share similar ideas, enable cooperation and compatibility.

Our goals include:

  • good usability
  • pretty good privacy
  • anonymity
  • self-sovereignity
  • sustainability
