Petoron Seal Contracts (PSC)
PSC is an irreversible, binary, offline system of digital agreements without code execution.
Each contract is a fixed cryptographic promise, signed by the participants and time limited (TTL).
PSC does not require a blockchain, API or internet. It works like a seal: once and. forever.
Key features
- Binary format only (no JSON, YAML or text declarations)
- TTL (time to live) is embedded in the file
- Participant signatures (Ed25519)
- executed - flag protects against reuse
- Signatures are external (.sig), not embedded.
- Support for manual deletion (burn)
- Full compatibility with PTBC (ability to encrypt PSC)
CLI commands :))
Generate keys: python3 cli/psc_cli.py genkey --output userA
Create contract: python3 cli/psc_cli.py create contract.txt --pubkeys userA.pub --ttl 3600 --output contract.psc
Sign: python3 cli/psc_cli.py sign contract.psc --private userA.priv --output userA.sig
Verify signature: python3 cli/psc_cli.py verify contract.psc --sig userA.sig --public userA.pub
Verify all signatures: python3 cli/psc_cli.py verify-all contract.psc --sigs userA.sig --pubs userA.pub
Check status: python3 cli/psc_cli.py status contract.psc
Execute contract: python3 cli/psc_cli.py execute contract.psc --sigs userA.sig --pubs userA.pub
Delete contract: python3 cli/psc_cli.py burn contract.psc
*PSC can be encrypted with the Petoron Time Burn Cipher for complete privacy: python3 python3 ptbc_cli.py encrypt contract.psc contract.ptbc --ttl 600
Dependencies: Python 3.7+ PyNaCl (pip install pynacl)
That's kind of it, I give it to you :))
