The Open Source Hub is looking for speakers, maintainers, and contributors to share their work and knowledge across our three tracks. 

🎯Tracks

• Open Source 101
  For newcomers to open source. Share open source culture, glossaries, fundamentals, and hands-on guidance to help attendees make their first contribution.

• Open Source Careers
  For developers making the leap from Web2 to Web3. Topics include navigating grants and RPGF, the Protocol Guild, maintainer sustainability, and building a career as an independent contributor or maintainer in the Ethereum ecosystem.

• All Layers Open
  Open source across every layer of the stack — software, firmware, and hardware. From Ethereum clients, L2s, and protocols to developer tools, operating systems, and the physical devices that make it all run — plus how emerging technologies intersect with open source at each layer.

🎤 Session Formats

Choose the format that best fits your topic:

• Onchain Quiz (20 min): Fun, interactive sessions testing open source knowledge and fundamentals.

• Ask Me Anything ( 20 min): Open Q&A on your experience — careers, funding, maintaining projects, or contributing.

• Lightning Talk (5 min): Quick showcases of a project, tool, or idea across any layer of the stack.

• Workshop (45 min): Hands-on, guided sessions where attendees follow along and build something.

📜 Please note that the content of your session including your presentation slides, code, examples, and other materials you choose to share will be published and made available to the community under the Creative Commons Attribution 4.0 International (CC BY 4.0) license.
