AI Treasure Hunt

The Challenge

Do you store your private keys in the cloud? Is it safe for companies to train ai models on your "anonymized" data?

We hid a SECRET HASH inside of GPT2 (a deep learning language model), "interrogate" it to win a bounty in CHAI (Dai DSR derivative token).

How To Play

1. Visit https://colab.research.google.com/drive/1Td1jtuMxIC_2RcLxM56FucVEyK_G3uB2 and follow the instructions to interrogate the AI for the secret hash.

2. Visit justsmartcontracts.dev

3. Click 'Add Contract'

4. Enter the following info: (click to select info)

   • Name:
     AI Treasure Hunt

   • Address:
     0xebdd3Bd175D0A08e2F1FDa768a75969105B6F5F9

   • ABI:
     [{"constant":true,"inputs":[],"name":"answerHash","outputs":[{"name":"","type":"bytes32"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"answer","type":"string"}],"name":"submit","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"claimed","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"inputs":[],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"payable":true,"stateMutability":"payable","type":"fallback"},{"anonymous":false,"inputs":[{"indexed":false,"name":"logText","type":"string"}],"name":"Log","type":"event"},{"anonymous":false,"inputs":[{"indexed":false,"name":"logText","type":"string"},{"indexed":false,"name":"hash","type":"bytes32"}],"name":"LogHash","type":"event"},{"anonymous":false,"inputs":[{"indexed":false,"name":"addy","type":"address"}],"name":"LogAddess","type":"event"}]

5. Press "Add"

6. You can see if the prize was already claimed from the "claimed" property

7. You can see the hash of the winning answer from the "answerHash" property

8. To submit an answer to the challenge, click "Operations", then "submit"

9. Enter your proposed answer (the secret hash!), and click "Generate"

10. Click "Metamask" and allow the page to read your address

11. Click "Sign" and confirm the transaction with Metamask

12. If you are the first to find the correct secret, you will receive 20 CHAI!
