Sustainable Blockchain Hackathon

June 23 - July 18, 2022

Blockchains are great for making transparent, verifiable claims and this means that there is a world of Web3 environmental tools to explore and create. Filecoin Green aims to turn sustainability into a Web3 superpower, and we need your help! If you are a builder interested in laying the foundation for tomorrow’s verifiably sustainable web, come join us for the Sustainable Blockchain Hackathon. All are welcome - whether you are deep into #Refi or just want to learn how to make the environmental impacts of your projects more transparent.

Do you believe in making the next generation of the internet as “green” as possible? Come and build sustainable, environmentally friendly tools at the Sustainable Blockchain Hackathon.
