Pyth oracles & Quantum Risk
Verdict
Pyth oracle publishers are not quantum-proof by default. Feed integrity depends on classical publisher signatures and aggregation design.
Overview
Pyth already has a protocol page; this spoke emphasizes publisher/oracle-key inventory for DeFi consumers.
Cryptographic profile
- Signatures: Host-chain account signatures for role holders (typically classical ECDSA/Ed25519), Multisig/module keys as deployed
- Hash: Host-chain dependent
- Public-key exposure: Publisher keys and network participants
- Hosts/context: Pyth price feeds multi-chain
What breaks
- Compromise of oracles related keys for Pyth
- Equating role separation or multisig with post-quantum algorithms
- Untracked multi-chain deployments of the same protocol
Mitigations
- Document privileged addresses from official docs per chain
- Hardware/MPC for guardians, admins, and large governors
- Return to /is-quantum-proof/pyth for protocol context
- Use category hubs: lending, dex, perps, stablecoins
