Cases/Fairblock
Fairblock ensures secure, automated key recovery for resilient AI systems with Phala
Solutions Implemented
Key Generation & Encryption
Private keys are generated in Phala's TEE enclave, encrypted via threshold encryption, and split into shares stored on Fairblock's FairyRing MPC network.
Liveness Monitoring
Smart contracts (e.g., CosmWasm) track TEE activity by periodic encrypted key submissions, acting as failure detectors.
Automated Recovery
If the TEE fails, contracts trigger Fairblock's MPC network to privately decrypt and reconstruct keys without exposing shares.
Conditional Decryption
Recovery requires predefined criteria (e.g., TEE inactivity) and authorization via on-chain governance.
Hardware-Agnostic Migration
Recovered keys are securely migrated to new TEE instances, avoiding vendor lock-in.
Key Benefits
Zero Trust Key Management
Keys never leave TEEs in plaintext; MPC ensures no single entity accesses full keys.
Resilient AI Systems
Automated recovery prevents data loss from crashes/reboots, critical for mission-critical AI.
Decentralized Security
Eliminates centralized backups via smart contract-governed workflows and MPC.
Auditable Compliance
TEE attestations and MPC transparency enable verification of key integrity.
Future-Proof Flexibility
Supports cross-hardware migration and integration with accountable MPC frameworks.
