One of the most novel aspects of Enclave: 

🔑 single-use keys

Each computation runs with fresh, ephemeral keyshares. No rotation. No residue.

A protocol for Encrypted Execution Environments

Single-use keys in action:

📦 Auctions: Each sealed-bid auction uses its own keys, preserving bidder confidentiality and eliminating leakage between runs.

🗳️ Ballots: Each vote is encrypted and tallied in a unique execution environment. No persistent key = no risk of future decryption.

🤖 AI Inference: Run provable AI inference on private inputs—health data, financial signals, or personal preferences—without exposing data. Afterward, nothing remains.

Enclave removes the need for key management rituals.

Single-use keys = stronger guarantees, lower risk, less overhead.

Why it matters:
🔹No long-term secrets to manage
🔹No central keyholder
🔹No cascading failures from compromised keys
