Secure Scuttlebutt (SSB) is an application-level, secure and persisted publish/subscribe system that has gained popularity in the decentralized Web movement. The aim of this workshop is to bring together researchers, software builders and members of the SSB community to study the properties and potential of Secure Scuttlebutt. The workshop is open to other decentralized approaches and networking technologies e.g. DAT, Holochain, IPFS or SOLID, as problems and technologies often have considerable similarities. Also, a SSB tutorial precedes the workshop, helping people to get familiar with the Secure Scuttlebutt technology and value system in short time. Limited travel and accommodation grants are available to help facilitate attendance from people without institutional funding We’ve received several applications, this grant opportunity is now closed. A huge thank you to SSBC and Planetary for providing financial support 💗

For participants of the paper museum tour, lunch will happen from 11h30-12h30 so that we will arrive on time for the activity at 13h.

Travel and Accommodations

You will have to organize travel and accommodations yourself. Basel is easily accessible by train and by plane. To share accommodation costs, you can synchronize with other participants.

Volunteering and Self-Organization

Most of the program will be done in a participant-driven unconference style. You can already think about sessions you’d like to host, discussions you’d like to initiate, etc. And if you feel like it, why not prepare a lightning talk?

Also, we’d love to see people take responsibility for some part of the event: perhaps you’d like to coordinate the preparation of a meal, host the lightning talks, know a way of gently raising people’s energy on Monday morning, or see another opportunity that is currently missing in the schedule? Then please reach out to us and we’ll make sure you can have your fun =). Any suggestions for vegan recipes are greatly appreciated.

You can also already discuss with other participants via:

Attendance Fees and Registration

  1. Which day(s) do you plan to attend?
  2. Do you plan to give a talk? Which topic?
  3. Will you attend the Paper Museum activity?
  4. Any initiative in helping run the event you would like to share?
