Enigma

Enigma is a privacy protocol stack built on Ethereum, with the ENX token driving resource allocation, governance, and access control across encrypted communication, stealth network routing, and decentralized identity primitives. Execution stays off chain to preserve privacy and scalability, while Ethereum handles settlement and enforcement: after a node completes work off chain it generates a cryptographic proof, the contract releases ENX payment only if verification passes, and failed verification triggers slashing under defined conditions.

The documentation lists four slashing triggers: missed heartbeats or timeouts, failed on-chain verification, double signing, and collusion detected through statistical anomaly detection. The token follows the ERC-20 standard with a total supply of 100 million, and is used to unlock privacy services, stake, and open token-gated privacy layers. The project describes its architecture through the RAVID security framework and divides construction into eras, starting the first era in 2025 with a stealth tunnel prototype and the ENX token.
