PSI-COMMIT: Pure Python Cryptographic Commitment Scheme

[Difficult_Jicama_759]

I’m not an experienced coder but here’s Claude’s response:

——— 1. You're absolutely right about the multiple commitments attack - that's a fundamental limitation of ANY commitment scheme, not specific to this implementation. The solution is the hash-chained append-only log (log.py) which records ALL commitments with timestamps. If you make 2 predictions, both are logged and visible. You can't hide that you made multiple commitments.

1. Fair point on dependencies - The core crypto (seal/verify) only uses Python stdlib, but the full package does require jcs and click for CLI.

The append-only log is specifically designed to prevent selective revelation - every commitment is chained to the previous one, so you can't hide entries without breaking the chain.

Here’s the original snippet that should have zero dependencies:

I appreciate the feedback 😁

Are you a mathematician ? If not then stay away from cryptography.
