人工智慧(Artificial Intelligence,簡稱AI)是指透過計算機技術實現的智慧。它是一種模擬人類智慧的技術,可以讓計算機像人一樣思考、學習、推理和判斷。人工智慧技術包括機器學習、深度學習、自然語言處理、計算機視覺等。人工智慧技術已經廣泛應用於各個領域,如智慧家居、智慧醫療、智慧交通、智慧製造等。



量化合約系統是一種基於演演算法和人工智慧技術的自動交易系統,它可以根據預設的交易策略和規則,自動執行交易操作,以實現投資收益最大化。量化合約機器人通常使用大量的歷史資料和實時市場資料進行分析和預測,以確定的交易時機和交易方向。它們可以在不間斷的24小時交易市場中執行,以快速響應市場變化和機會。量化合約機器人已經成為了許多投資者和交易者的工具,因為它們可以提高交易效率和準確性,同時降低交易風險和成本系統開發180.3831.97z4。



Deployer API deployer物件提供了方法用於簡化智慧合約的部署。deployer.deploy(contract, args…, options)引數contract為使用artifacts.require引用的智慧合約物件。引數args...為智慧合約的建構函式的引數,用於初始化智慧合約。引數options用於指定from,gas及overwrite等資訊,overwrite用於重新部署某個已經完成部署的智慧合約,預設的options引數在bottle.js檔案中配置

例子:

// Deploy a single contract without constructor arguments

deployer.deploy(A);


// Deploy a single contract with constructor arguments

deployer.deploy(A, arg1, arg2, ...);


// Don't deploy this contract if it has already been deployed

deployer.deploy(A, {overwrite: false});


// Set a maximum amount of gas and `from` address for the deployment

deployer.deploy(A, {gas: 4612388, from: "0x...."});


// External dependency example:

//

// For this example, our dependency provides an address when we're deploying to the

// live network, but not for any other networks like testing and development.

// When we're deploying to the live network we want it to use that address, but in

// testing and development we need to deploy a version of our own. Instead of writing

// a bunch of conditionals, we can simply use the `overwrite` key.

deployer.deploy(SomeDependency, {overwrite: false});



透過promise物件可以執行任意的部署步驟並呼叫指定的智慧合約內部方法來進行互動

例子:

var ERC20 = artifacts.require("../contracts/Erc20.c")


module.exports = function (deployer, a) {

    deployer.deploy(ERC20, "1000000", "bitcoin", "BTC").then(function (instance) {

        deploy = instance;

        return deploy.GetTotalSupply()

    }).then(function (totalSupply) {

        console.log("totalSupply", totalSupply.toString());

        return deploy.GetDecimals();

    }).then(function (decimals) {

        console.log("decimals", decimals.toString());

        return deploy.GetTokenName();

    }).then(function (tokenName) {

        console.log("tokenName", tokenName);

        return deploy.GetAmount("0x122369f04f32269598789998de33e3d56e2c507a")

    }).then(function (balance) {

        console.log("balance", balance.toString());

    })

};
