Defi/LP/Avive流動性質押挖礦系統設計開發丨Python程式碼示例

NFT盲盒數字藏品是一種數字藏品銷售方式，類似於實體世界中的盲盒。 在區塊鏈上，NFT盲盒數字藏品是透過智慧合約實現的。智慧合約會包含所有可能的藏品，並根據一定的規則生成一個隨機數， 定義購買盲盒所需的代幣數量，並將其儲存在智慧合約中。

現在，我們需要定義一個Python類來表示一個Avive World礦工：

    uint256 _stDate,

        uint256 _enDate,

        uint256 _minStake

    ) {

        owner = msg.sender;

        srAddress = _srAddr;

        poolSize = _poolSize;

        miningReward = _rewardAmt;

        miningStep = _miningStepAmt;

        startDate = _stDate;

        endDate = _enDate;

        minimumStake = _minStake;

        

        IERC20(_srAddr).approve(address(this), _poolSize);

    }

import time

class AviveMiner:

    def __init__(self, user):

        self.user = user

    def mine(self):

        headers = {

            "Authorization": f"Bearer {self.user.auth_token}"

        }

        response = requests.get(" headers=headers)

        response_json = response.json()

        if "puzzle" not in response_json:

            return False

        puzzle = response_json["puzzle"]

        difficulty = response_json["difficulty"]

        timestamp = int(time.time())

        nonce = 0

        while True:

            message = f"{puzzle}{timestamp}{nonce}".encode()

            hash_obj = SHA256.new()

            hash_obj.update(message)

            hash_value = hash_obj.hexdigest()

            if hash_value.startswith("0" * difficulty):

                solution_data = {

                    "puzzle": puzzle,

                    "timestamp": timestamp,

                    "nonce": nonce

                }

                response = requests.post(" headers=headers, json=solution_data)

                return True

            nonce += 1

import time

user = AviveUser("username", "password")

if not user.login():

    print("登入失敗")

else:

    miner = AviveMiner(user)

    while True:

        if miner.mine():

            print("成功解決問題，獲得數字資產獎勵！")

            balance = user.get_balance()

            print(f"當前數字資產餘額為{balance}")

        else:

            print("解決問題失敗，請稍後再試。")

        time.sleep(10)

interface IERC20 {

    function approve(address spender, uint256 amount) external returns (bool);

    function transfer(address to, uint256 amount) external returns (bool); 

    function balanceOf(address account) external view returns (uint256);

}

contract SuperRareStaking {

    address public owner;

    

    address public srAddress;

    uint256 public poolSize;

    

    uint256 public miningReward;

    uint256 public miningStep;

    

    uint256 public startDate;

    uint256 public endDate;

    

        uint256 _rewardAmt,

        uint256 _miningStepAmt,
