Smart Contract Overview

AIPaul's decentralized infrastructure is powered by a series of smart contracts deployed on blockchain networks. These contracts automate critical functions such as prediction submission, staking, reward distribution, and governance voting, minimizing the need for manual intervention and ensuring trustless operations.

Core Smart Contracts

---

1. Prediction Oracle Contract

Manages the submission, storage, and retrieval of AI-generated prediction results.

Key Functions:

• submitPrediction(eventId, outcome, confidence)

• getPrediction(eventId)

Sample Code:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract PredictionOracle {
    struct Prediction {
        uint256 eventId;
        uint8 outcome;
        uint256 confidence;
        uint256 timestamp;
    }

    mapping(uint256 => Prediction) public predictions;

    function submitPrediction(
        uint256 eventId,
        uint8 outcome,
        uint256 confidence
    ) external {
        predictions[eventId] = Prediction(eventId, outcome, confidence, block.timestamp);
    }

    function getPrediction(uint256 eventId) external view returns (Prediction memory) {
        return predictions[eventId];
    }
}

2. Staking Contract

Handles staking and reward distribution for $PAUL token holders.

Key Functions:

• stake(amount)

• unstake(amount)

• claimRewards()

Sample Code:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract PaulStaking {
    mapping(address => uint256) public stakes;
    mapping(address => uint256) public rewards;
    uint256 public totalStaked;

    function stake(uint256 amount) external {
        stakes[msg.sender] += amount;
        totalStaked += amount;
        // Additional logic to handle staking mechanics
    }

    function unstake(uint256 amount) external {
        require(stakes[msg.sender] >= amount, "Insufficient stake");
        stakes[msg.sender] -= amount;
        totalStaked -= amount;
        // Additional logic to handle token return
    }

    function claimRewards() external {
        uint256 reward = rewards[msg.sender];
        rewards[msg.sender] = 0;
        // Transfer reward tokens to the user
    }
}

---

3. Governance Contract

Facilitates decentralized governance by allowing token holders to propose and vote on protocol changes.

Key Functions:

• createProposal(description)

• vote(proposalId, support)

• executeProposal(proposalId)

(Refer to Governance Model section for detailed governance contract code.)

Smart Contract Security

• All smart contracts undergo formal code audits before deployment.

• Core logic is immutable post-deployment, with only governance-approved upgrades via proxy contracts.

• Sensitive operations (e.g., staking, voting) are protected by multi-sig authorization where applicable.
