Welcome to FMChain, a blockchain which uses Rubik's Cube Fewest Moves solves as Proof-of-Work!

  1. ✍️ Write Words
    Add any text. It becomes part of the block and is used to generate your cube scramble.
  2. 🧩 Solve the Cube
    Use the fewest moves to solve the scramble that is created from your block's hash.
  3. ⛓️ Extend the Chain
    Longest chain wins! Ties go to the branch with the most efficient last solve.

Chain Rules: You can only extend chains from last week or earlier (weeks run Monday-Sunday). This creates a cooling-off period that prevents spam in the main chain and rewards thoughtful contributions.

Thanks for playing and have fun! ♥️
