Sign a wish

Name a Solana program and the price you would pay for its source once a machine has shown it works. Nothing is locked: you sign a message, and a proof made on your wish gives you 7 days to buy it before anyone else.

What you would pay to decrypt a passing source. You pay nothing now; a proof made on your wish gives you 7 days to buy it first.
Connect the wallet that signs the wish. No transaction, only a signed message.
