Zero-trust tile provenance — Ed25519 signing, hash chain verification, trust scoring for PLATO tiles
Project description
🔐 plato-provenance
Zero-trust tile provenance — Ed25519 signing, hash chain verification, trust scoring.
Install
pip install plato-provenance
What It Does
Every PLATO tile gets a cryptographic provenance chain. Know who created it, when it was modified, and verify its integrity without trusting any single agent.
Key Features
- Ed25519 Signing — Every tile is signed by its creator
- Hash Chain — Tamper-evident modification history
- Trust Scoring — Weighted confidence based on agent reputation
- Verification API — Validate any tile's full provenance chain
Usage
from plato_provenance import ProvenanceChain, TileSigner
signer = TileSigner(agent_id="oracle1")
signed_tile = signer.sign(tile_data)
chain = ProvenanceChain()
chain.verify(signed_tile) # Returns verification result
