Privacy Preserving Smart Contracts
summary
A privacy layer called Enigma runs secret contracts that execute on encrypted inputs inside Intel hardware enclaves (Intel SGX), posts a hash to Ethereum, and returns only an aggregate verdict on-chain. Each task is run by a quorum (example: core five workers) who stake tokens and rotate per epoch; state is stored as encrypted deltas and replayed into enclaves in memory. Planned mitigation for enclave attacks is splitting work with multi‑party computation (MPC) across up to ~100 nodes; current system is live but moving toward MPC.
