[polarker]

Parent issue: https://github.com/alephium/ralph-example/issues/26

Objective:

Develop a secure system for smart contracts to request and receive off-chain data on-chain, ensuring data integrity and reliability.

Description:

This issue focuses on implementing a mechanism for smart contracts to request specific data from the oracle and securely deliver it on-chain.

Tasks:

1. Create a function for smart contracts to send data requests to the oracle.
2. Develop a secure mechanism to fetch requested off-chain data and deliver it to the requesting contract on-chain.
3. Ensure the mechanism includes safeguards for data integrity and delivery security.
4. Write unit tests to validate request and delivery functionality, including edge cases.

Acceptance Criteria:

• Smart contracts can send requests for specific off-chain data.
• Data is fetched and securely delivered on-chain.
• Mechanism includes safeguards to maintain data integrity.
• Tests cover normal and edge-case scenarios.
