This project bridges UMA's Optimistic Oracle solution to Secret Network, enabling the secure and verifiable resolution of arbitrary questions and requests.

Value Proposition

Integrating UMA's Oracle with Secret Network allows for the inclusion of complex data into the blockchain, which supports advanced applications like:

Privacy-preserving prediction markets
Regulated financial and medical protocols requiring real-time data and user confidentiality
Private lending and insurance protocols

How It Works

Posting a Contest:
- A contest consisting of an ID and event details (including the UMA request query) is posted to the Prediction Market smart contract on Secret Network.
Querying Contests:
- The SP-Relayer node continuously queries the PM contract for new contests that need resolution.
- The query returns contest information and a signature verifying the data originated from the contract.
Initializing the Market:
- The SP-Relayer parses the query content to initialize a new Market (question/request) on the Sepolia SP-UMA-Request contract through a Sepolia network transaction.
Asserting an Answer:
- An answer is asserted as truthful and enters a dispute window, during which it can be challenged.
Settling the Outcome:
- If the answer is not challenged during the dispute window, the SP-Relayer node settles the outcome.
- This action triggers the Axelar GMP route back to the SP-Answer Secret contract on Secret Network.
Bet Resolution:
- When a user claims their bet, the Prediction Market/Contest contract queries the Answer contract for the bet's resolution.

Decentralization and Automation

SP-Relayer Node: Exists solely for automation, ensuring smooth operations without requiring constant manual intervention.
Decentralized Fulfillment: Thanks to the public/private keys stored on Secret Network, any motivated entity can fulfill the steps usually handled by the SP-Relayer, ensuring the process remains decentralized and trustless.

Technical Implementation

Secret Network's Private Contract State: Utilizes public/private keys on-chain for verifiable sources of truth.
Axelar's General Message Passing Protocol: Ensures data integrity throughout the process.

Step 1: Posting a Contest https://testnet.ping.pub/secret/tx/42D0978CBDE4CF7981450343A74E207A0E148030B3C979969C1A598F0E8ECA2B
Step 2: Querying & Signing Contests
Step 3: Initializing the Market on Sepolia https://sepolia.etherscan.io/tx/0x7b44b6027f758c4ae15a6bd68bb9c7c70178776c4a2801b91549ad55af6b5bae
Step 4: Asserting an Answer https://sepolia.etherscan.io/tx/0x8a1d83df12a7829aafca76ef4c2b84b5f232e2272767901fa4414285e1a98891
Step 5: Settling the Outcome https://sepolia.etherscan.io/tx/0x0e481fb0ffe48754a789d38e346aace570ec2f7b0d8f35f07d939284fef88114
Step 6: Simulation of the Axelar step, as they do not support pulsar-3, with our SP-Relayer relaying the answer back to our Answer contract https://testnet.ping.pub/secret/tx/7A15FE0BBBA3DF51D4D2E073309A1ADD78DDCAF304D43BB8D1E726E789A504EA

This integration can enhance the functionality of Secret Network by enabling complex, secure, and verifiable data processing.
