🕶️ Private Execution → Public Settlement on NEAR

NEAR Private Execution

What it does

Private execution layer for NEAR:

• Sensitive logic runs off-chain (TEE / zk-lite)
• Only commitments & proofs settle on-chain
• No changes to NEAR consensus

Why it matters

• Public blockchains leak business logic
• Enables private DeFi, auctions, games, voting

Architecture

1. Gateway contract (NEAR)
2. Off-chain executor (TEE / zk-lite)
3. Verifier contract
4. Public settlement

Demo flow

1. User submits job
2. Private execution off-chain
3. Commitment verified on-chain
4. Callback executed

Status

✔ Contracts deployed on NEAR Testnet
✔ End-to-end demo flow
✔ Open-source

Run Demo

bash scripts/deploy.testnet.sh

bash scripts/demo.testnet.sh

Quick demo (NEAR testnet)
