Sky oracles & Quantum Risk
Verdict
Sky/Maker-class oracles are not quantum-proof. Medianizers and feed signers are classical integrity roots for the stable system.
Overview
Stablecoin solvency narratives depend on prices and peeks—inventory oracle modules explicitly.
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: Oracle security module feeds and medianizers as deployed
- Hosts/context: OSM/oracle security module lineage
What breaks
- Compromise of oracles related keys for Sky
- 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/sky for protocol context
- Use category hubs: lending, dex, perps, stablecoins
