链游CryptoMines系统逻辑开发《I76开发2072制作9II9》链游CryptoMines系统逻辑开发，and is mostly limited to smart contracts between individuals and institutions,There are almost no smart contracts between individuals.The reason is the problem of"trust".We will find that as long as we talk about contracts,most of them are strangers.There is such a need between strangers,and it also has something to do with money.If we make an agreement without a third party as a guarantee,I call you the money,and you break the contract,what if you don't admit it?

简单来说，智能合约就是一种把我们生活中的合约数字化，当满足一定条件后，可以由程序自动执行的技术。我们的生活中处处充满着合约，就好比你跟我做了一个约定，我们订好了奖惩措施，但由于种种原因可能没法履行其中的条款，出现了无法履约的情况，而在进入赔付环节，往往会出现毁约，失约，耍赖的情况，11后弄得有理说不清。

Therefore,smart contracts have not been popularized between individuals.Later,with the emergence of blockchain,people found that blockchain and smart contracts are very consistent,because many characteristics of blockchain,such as decentralization and data tamperability,can solve the trust problem between strangers from a technical point of view,which makes the large-scale application of smart contracts possible,The beginning of this stage is marked by the birth of Ethereum.

但是如果我们把约定通过代码的形式，录入区块链中，一旦触发约定时的条件，就会有程序来自动执行，这就是智能合约。

智能合约保证一切都将以编码的方式完成。由于它们不是非常复杂的程序，因此通常可以通过一些基本的编程知识来阅读和理解这些代码。这对于保持一切都在地面上并促进与网络中其他参与者的良好工作关系非常重要。

Smart contract is a"computer transaction agreement that implements the terms of the contract".All users on the blockchain can see the smart contract based on blockchain.However,this will make all vulnerabilities,including security vulnerabilities,visible and may not be repaired quickly.Such attacks are difficult to solve quickly.For example,in June 2016,the daother vulnerability caused a loss of$50million,and developers tried to reach a consensus solution.Dao's program has a period of delay before hackers delete funds.A hard fork in Ethereum software completed the attacker's fund recovery before the deadline expired.

智能合约，Smart Contract，是一种旨在以信息化方式传播、验证或执行合同的计算机协议。智能合约是一套以数字形式定义的承诺，承诺控制着数字资产并包含了合约参与者约定的权利和义务，由计算机系统自动执行。智能合约程序不只是一个可以自动执行的计算机程序，它本身就是一个系统参与者，对接收到的信息进行回应，可以接收和储存价值，也可以向外发送信息和价值。这个程序就像一个可以被信任的人，可以临时保管资产，总是按照事先的规则执行操作。

In the future,based on the Internet platform,blockchain technology will be used to make a new change.Now is the key turning point.If there are any tie points in the blockchain that try to tamper with data privately,and most nodes do not change,this tampering behavior will then be rejected by the whole blockchain to ensure the consensus and security of the whole network.

数字形式定义的承诺，包括合约参与方可以在上面执行承诺的协议，其设计初衷是希望通过将智能合约内置到物理实体来创造各种灵活可控的智能资产，自动售卖机在一定程度上代表了早期智能合约的实践。通过编写智能合约，执行过程中涉及的实体不再需要依赖第三方去监管和兑现各方的承诺，而是依赖于合约代码的自动执行，只要保证合约执行环境可信，就可以实现各方承诺的正确履行。区块链技术的中心化、不可篡改、过程透明、可追踪等优点天然适合智能合约。智能合约部署在区块链平台，区块链技术担保其不被篡改，合约双方对交易不可否认，为智能合约执行提供了安全保障。
