FumbleChain is a deliberately insecure blockchain. Read the guides, complete the CTFs, learn what the common development pitfalls are - and how to avoid them.
FumbleChain is written in Python – so it’s easy to read and participate. You can also run an instance on your own machine using Docker.
This project seeks to raise awareness about blockchain security. Blockchain ecosystems aren’t inherently secure and FumbleChain is a platform where you can explore concepts and test your skills.
What we’ve created is just the start. Use it. Add new challenges. Help it grow and spread the word about blockchain security.
