# Ethernity Cloud

> Decentralized confidential computing ecosystem. Run code inside hardware-secured enclaves on 5,000+ community-operated nodes with on-chain Proof of eXecution.

Ethernity Cloud is a decentralized confidential computing ecosystem where community-owned Intel SGX nodes execute code inside hardware-secured enclaves. Every computation produces a cryptographic Proof of eXecution (PoX) written on-chain to Polygon or Bloxberg. The node operator cannot see your data or code.

## Key Facts

- Founded: 2018
- Mainnet: Live since 2023
- Active nodes: 5,000+
- Supported networks: 7 (Polygon Mainnet, Bloxberg Mainnet, + 5 testnets)
- SDK: Node.js (@ethernity-cloud/sdk-js) and Python (ethernity-cloud-sdk-py)
- Hardware: Intel SGX enclaves (TDX support via EC 2.0)
- Company: Ethernity Cloud Ltd., Malta (C 99997)
- Tokens: ETNY (Bloxberg, staking) and ECLD (Polygon, operations) — both utility tokens, not securities

## Architecture

Three independent enclaves process every task:
1. TrustedZone (Gatekeeper) — Validates code and data checksums. Never executes client code.
2. SecureLock (Executor) — Runs client code in an isolated Intel SGX enclave. Even the node operator cannot read memory.
3. Validator — Independently validates the on-chain Proof of eXecution and unlocks payment to the operator. A forged proof is invalidated and can be slashed.

The enclaves communicate only through shared object storage (MinIO/IPFS). This separation of concerns prevents any single point of compromise.

## Developer Quick Start

npm install @ethernity-cloud/sdk-js
npx ecld-init       # Select runtime (Nodenithy/Pynithy) and network
npx ecld-build      # Build enclave image
npx ecld-publish    # Publish on-chain and execute

## Comparison

- vs AWS Nitro Enclaves: Ethernity Cloud is decentralized (community nodes, not Amazon hardware) with on-chain proof. AWS Nitro is centralized with no public verification.
- vs Azure Confidential Computing: Same Intel SGX hardware, but Ethernity Cloud removes the single-vendor trust requirement and adds on-chain proof.
- vs Phala Network: Ethernity Cloud uses a unique three-enclave isolation model (TrustedZone/SecureLock/Validator) and supports 7 blockchain networks.
- vs iExec: Ethernity Cloud offers triple-enclave isolation not found in iExec's architecture.

## Use Cases

- Confidential AI inference on encrypted data
- Private data processing (healthcare, finance, PII)
- Verifiable computation with on-chain proof for auditors and regulators
- Trustless serverless functions on community hardware
