		<title>智能合约是什麽</title>
	

	<center>
	<div style="max-width: 900px; text-align: left;">
​
<p>「智能合约」这个词这些年可谓相当火热。那智能合约到底是什麽？是真的神乎其神，还是有被夸大之嫌，这篇文章就来简要探讨一下。</p>
​
<h3 style="font-size: 22px; color: #2A3795; font-weight: bold;">智能合约是什麽</h3>

<p>智能合约这个名词，最早是在 1994 年由电脑科学家及密码学家 Nick Szabo 所提出，其对智能合约的定义是：</p>
​
<div style="color:#28AA2E; font-weight:bold; border: 1px solid #28AA2E; border-radius: 9px; padding: 10px 20px;"><p style="color:#28AA2E;" "="">智能合约的目标是为了达到现实生活中常见的「合约」条件（例如支付条款、留置权、保密性，甚至强制执行），最大限度地减少恶意和意外的情况，并最大限度地减少对可信中介的需求。相关的经济目标包括降低欺诈损失、仲裁和执行成本以及其他交易成本。</p> </div>
​
<p>浅显的说「智能合约」就是用一段高度可信的电脑程式，来制定「合约」条款，在达至特定条件时可以不受干扰的执行先前约定的逻辑。</p>
​
<p>近年来区块链技术的蓬勃发展，为智能合约提供了非常好的发展基础。区块链的透明性，分散性，不可更改性等特性，正好满足了一个可信的「智能合约」存在基础。</p>
​
<h3 style="font-size: 22px; color: #2A3795; font-weight: bold;">运作方式</h3>
​
<p>智能合约中「智能」二字可能听上去有点虚幻。其实「智能合约」就是一段部署到区块链网路上的一段程式码，区块链提供了一个类似伺服器的「程式运行环境」以供智能合约执行，智能合约执行后，将运行结果反馈到区块链上。从这个层面上来讲，「智能合约」和传统的程式码并无区别。其基本构成，也就是一系列的条件判断和数据纪录，例如：</p>
​
<ul>
	<li>如果当前时间是 2025 年，则这个地址可以获得 2 ETH；</li>
	<li>如果获得超过两个被授权人士允许，则用户可以提取 2 ETH </li>
</ul>
​
<p>等等！</p>
​
<p>「智能合约」和传统的程式码的较为不同之处在于运行环境不一样。 传统的程式码大多运行在中心化的伺服器中，而智能合约则是运行在去中心化的区块链上。而且基于区块链的不可更改性，发佈到区块链上的程式码本身不可更改（程式码不能更改不等于程式逻辑不能更改，下文会具体分析），合约执行的过程也相对透明，任何人都可以看到和验证合约执行结果。</p>
​
<h3 style="font-size: 22px; color: #2A3795; font-weight: bold;">实际应用</h3>
​
<p>基于区块链的透明性，分散性，不可更改等特性，智能合约可以被广泛运用在众多有着「去中心化」，「记账」，「数据纪录」，「逻辑判断」需求的领域。例如金融保险、医疗保健、供应链、博彩、物联网、政务处理等等行业或领域。</p>
​
<p>在金融行业， 因为银行的一些金融活动，例如汇款等操作，在现时的银行系统中是一个涉及到多系统，多机构的冗长过程，参与的机构众多，各方都需要付出时间和金钱成本。利用智能合约的技术，则可以提供更快捷，透明，点对点的资金流动，大大提升金融流动效率。因此，区块链和智能合约在金融行业的应用也越来越多，大到国家发行的数字人民币，小到去中心化交易系等等，智能合约技术在金融领域得到了非常广泛的应用。</p>
​
<p>不仅仅是金融行业，在其他领域，例如物流行业，智能合约也有着极大的「用武之地」。早在 2018 年，IT 巨头 IBM Corp. 和全球航运公司 AP Moller-Maersk Group 推出名为 TradeLens 的基于区块链创建的供应跟踪和供应链管理平台，而智能合约则在系统中发挥的作用至关重要。经过大量测试证明，该技术的使用能够有效减少文书工作的成本，减少运输时间，大大降低运营成本。</p>
​
<h3 style="font-size: 22px; color: #2A3795; font-weight: bold;">风险和局限</h3>
​
<p>儘管智能合约有很好的运用前景，但智能合约的风险和局限我们也要同样重视。</p>
​
<p>首先并不是所有场景都适合智能合约，儘管智能合约的确和普通程式一样可以编写业务逻辑，但是基于区块链的诸多限制和特性，无论是功能性还是运行效能，智能合约尚且不能和传统应用程式相提并论。因此，我们应该只在适合的场景下才採用智能合约技术，而不是将智能合约「神话化」，认为智能合约可以解决所有问题。</p>
​
<p>另外，智能合约编写漏洞所导致的安全问题，也是採用智能合约时需要考量的重点。因为智能合约的逻辑，如果没有做出特别处理，一旦发佈上区块链，则无法做出程式码层面的更改，因此如果没有经过严谨测试，合约程式中的漏洞将会导致不可挽回的后果。 因为智能合约代码疏漏导致的损失层出不穷，例如 Akutar NFT 的<a href="https://etherscan.io/address/0xf42c318dbfbaab0eee040279c6a2588fa01a961d" style="text-decoration:  underline; color:#2A3795;">智能合约</a>，就是因为将 <code>bidIndex</code> 错误的写为<code>totalBids</code> 这样一个超级简单的人为错误，而导致高达 11,539 ETH，当时价值 2 亿港元的资金永久封锁在了智能合约中。</p>
​
<p>很多人都说智能合约一经发佈则不可更改程式码或阻止程式执行，这个说法其实也并不准确。的确，智能合约的程式码本身一经发佈则不可更改，但是一个完整的智能合约不仅仅包括程式码本身，还有一系列的状态变数 (state variable)，这些状态变数可以透过调用预先写好的程式逻辑而被更改， 而且，因为状态变数的改变，智能合约完全可以执行截然不同的逻辑。 另外现时智能合约可以透过代理合约的方式，做到「逻辑更新」动作，即「可升级智能合约」。 </p>
​
<p>另外，目前有很多文章指出智能合约会自动执行，这个说法也有待斟酌。直到目前为止，基于 EVM 的区块链上的智能合约只有在被调用时才会被执行。所谓「调用」，可以是一个使用者钱包，也可以是其他的智能合约，但任何调用的最初始触发总是由使用者钱包所产生。换句话说，只要没有人主动调用，智能合约就不会运行。儘管区块链社区有类似<a href="https://medium.com/wavesprotocol/blockchain-trigger-a-tool-for-automatic-smart-contract-invocation-1cb2748c53be" style="text-decoration: underline; color:#2A3795;">智能合约自动运行的提案</a>，但目前并没有实际的标准和实现。所以对于有关「合约部署后就会自动执行」的说法并不完全准确。</p>
​
<h3 style="font-size: 22px; color: #2A3795; font-weight: bold;">结语</h3>
​
<p>智能合约作为区块链技术上的一大技术基础，有着广阔的应用前景。许多传统行业的应用，或多或少可以使用智能合约和区块链技术来简化流程，节省成本。 随着整个区块链行业的快速发展，智能合约技术亦会不断提升，从而逐步扩展更多应用场景。在 2022 年的今天，各大公司机构，甚至政府部门，都在逐渐研究运用区块链和智能合约相关技术的可行性。

尽早踏足区块链和智能合约领域，势必会在 web 3.0 发展如火如荼的当下抢佔先机，助其业务发展。</p>

	<div style="max-width: 900px; text-align: left;">
​
<p>「智能合約」這個詞這些年可謂相當火熱。那智能合約到底是什麼？是真的神乎其神，還是有被誇大之嫌，這篇文章就來簡要探討一下。</p>
​
<h3 style="font-size: 22px; color: #2A3795; font-weight: bold;">智能合約是什麼</h3>

<p>智能合約這個名詞，最早是在 1994 年由電腦科學家及密碼學家 Nick Szabo 所提出，其對智能合約的定義是：</p>
​
<div style="color:#28AA2E; font-weight:bold; border: 1px solid #28AA2E; border-radius: 9px; padding: 10px 20px;"><p style="color:#28AA2E;" "="">智能合約的目標是為了達到現實生活中常見的「合約」條件（例如支付條款、留置權、保密性，甚至強制執行），最大限度地減少惡意和意外的情況，並最大限度地減少對可信中介的需求。相關的經濟目標包括降低欺詐損失、仲裁和執行成本以及其他交易成本。</p> </div>
​
<p>淺顯的說「智能合約」就是用一段高度可信的電腦程式，來制定「合約」條款，在達至特定條件時可以不受干擾的執行先前約定的邏輯。</p>
​
<p>近年來區塊鏈技術的蓬勃發展，為智能合約提供了非常好的發展基礎。區塊鏈的透明性，分散性，不可更改性等特性，正好滿足了一個可信的「智能合約」存在基礎。</p>
​
<h3 style="font-size: 22px; color: #2A3795; font-weight: bold;">運作方式</h3>
​
<p>智能合約中「智能」二字可能聽上去有點虛幻。其實「智能合約」就是一段部署到區塊鏈網路上的一段程式碼，區塊鏈提供了一個類似伺服器的「程式運行環境」以供智能合約執行，智能合約執行後，將運行結果反饋到區塊鏈上。從這個層面上來講，「智能合約」和傳統的程式碼並無區別。其基本構成，也就是一系列的條件判斷和數據紀錄，例如：</p>
​
<ul>
	<li>如果當前時間是 2025 年，則這個地址可以獲得 2 ETH；</li>
	<li>如果獲得超過兩個被授權人士允許，則用戶可以提取 2 ETH </li>
</ul>
​
<p>等等！</p>
​
<p>「智能合約」和傳統的程式碼的較為不同之處在於運行環境不一樣。 傳統的程式碼大多運行在中心化的伺服器中，而智能合約則是運行在去中心化的區塊鏈上。而且基於區塊鏈的不可更改性，發佈到區塊鏈上的程式碼本身不可更改（程式碼不能更改不等於程式邏輯不能更改，下文會具體分析），合約執行的過程也相對透明，任何人都可以看到和驗證合約執行結果。</p>
​
<h3 style="font-size: 22px; color: #2A3795; font-weight: bold;">實際應用</h3>
​
<p>基於區塊鏈的透明性，分散性，不可更改等特性，智能合約可以被廣泛運用在眾多有著「去中心化」，「記賬」，「數據紀錄」，「邏輯判斷」需求的領域。例如金融保險、醫療保健、供應鏈、博彩、物聯網、政務處理等等行業或領域。</p>
​
<p>在金融行業， 因為銀行的一些金融活動，例如匯款等操作，在現時的銀行系統中是一個涉及到多系統，多機構的冗長過程，參與的機構眾多，各方都需要付出時間和金錢成本。利用智能合約的技術，則可以提供更快捷，透明，點對點的資金流動，大大提升金融流動效率。因此，區塊鏈和智能合約在金融行業的應用也越來越多，大到國家發行的數字人民幣，小到去中心化交易系等等，智能合約技術在金融領域得到了非常廣泛的應用。</p>
​
<p>不僅僅是金融行業，在其他領域，例如物流行業，智能合約也有著極大的「用武之地」。早在 2018 年，IT 巨頭 IBM Corp. 和全球航運公司 AP Moller-Maersk Group 推出名為 TradeLens 的基於區塊鏈創建的供應跟踪和供應鏈管理平台，而智能合約則在系統中發揮的作用至關重要。經過大量測試證明，該技術的使用能夠有效減少文書工作的成本，減少運輸時間，大大降低運營成本。</p>
​
<h3 style="font-size: 22px; color: #2A3795; font-weight: bold;">風險和局限</h3>
​
<p>儘管智能合約有很好的運用前景，但智能合約的風險和局限我們也要同樣重視。</p>
​
<p>首先並不是所有場景都適合智能合約，儘管智能合約的確和普通程式一樣可以編寫業務邏輯，但是基於區塊鏈的諸多限制和特性，無論是功能性還是運行效能，智能合約尚且不能和傳統應用程式相提並論。因此，我們應該只在適合的場景下才採用智能合約技術，而不是將智能合約「神話化」，認為智能合約可以解決所有問題。</p>
​
<p>另外，智能合約編寫漏洞所導致的安全問題，也是採用智能合約時需要考量的重點。因為智能合約的邏輯，如果沒有做出特別處理，一旦發佈上區塊鏈，則無法做出程式碼層面的更改，因此如果沒有經過嚴謹測試，合約程式中的漏洞將會導致不可挽回的後果。 因為智能合約代碼疏漏導致的損失層出不窮，例如 Akutar NFT 的<a href="https://etherscan.io/address/0xf42c318dbfbaab0eee040279c6a2588fa01a961d" style="text-decoration:  underline; color:#2A3795;">智能合約</a>，就是因為將 <code>bidIndex</code> 錯誤的寫為<code>totalBids</code> 這樣一個超級簡單的人為錯誤，而導致高達 11,539 ETH，當時價值 2 億港元的資金永久封鎖在了智能合約中。</p>
​
<p>很多人都說智能合約一經發佈則不可更改程式碼或阻止程式執行，這個說法其實也並不準確。的確，智能合約的程式碼本身一經發佈則不可更改，但是一個完整的智能合約不僅僅包括程式碼本身，還有一系列的狀態變數 (state variable)，這些狀態變數可以透過調用預先寫好的程式邏輯而被更改， 而且，因為狀態變數的改變，智能合約完全可以執行截然不同的邏輯。 另外現時智能合約可以透過代理合約的方式，做到「邏輯更新」動作，即「可升級智能合約」。 </p>
​
<p>另外，目前有很多文章指出智能合約會自動執行，這個說法也有待斟酌。直到目前為止，基於 EVM 的區塊鏈上的智能合約只有在被調用時才會被執行。所謂「調用」，可以是一個使用者錢包，也可以是其他的智能合約，但任何調用的最初始觸發總是由使用者錢包所產生。換句話說，只要沒有人主動調用，智能合約就不會運行。儘管區塊鏈社區有類似<a href="https://medium.com/wavesprotocol/blockchain-trigger-a-tool-for-automatic-smart-contract-invocation-1cb2748c53be" style="text-decoration: underline; color:#2A3795;">智能合約自動運行的提案</a>，但目前並沒有實際的標準和實現。所以對於有關「合約部署後就會自動執行」的說法並不完全準確。</p>
​
<h3 style="font-size: 22px; color: #2A3795; font-weight: bold;">結語</h3>
​
<p>智能合約作為區塊鏈技術上的一大技術基礎，有著廣闊的應用前景。許多傳統行業的應用，或多或少可以使用智能合約和區塊鏈技術來簡化流程，節省成本。 隨著整個區塊鏈行業的快速發展，智能合約技術亦會不斷提升，從而逐步擴展更多應用場景。在 2022 年的今天，各大公司機構，甚至政府部門，都在逐漸研究運用區塊鏈和智能合約相關技術的可行性。

盡早踏足區塊鏈和智能合約領域，勢必會在 web 3.0 發展如火如荼的當下搶佔先機，助其業務發展。</p>

With this knowledges, it is time to ask the critical question: How to integrate X To Earn into business development? The following three questions are the keys.</span></p><div class="raw-html-embed"><div style="text-align: center;">

</div><p>&nbsp;</p><p>&nbsp;</p><div class="raw-html-embed"><h3 style="font-family: heebo; font-size: 20px;color: #2A3795;">Think About Why You Need To Create a X To Earn Project?</h3></div><p><span style="color:rgb(0,0,0);">It is not a sufficient reason for you to create your X To Earn projects just to following the trend. The core reason should backed by your understanding of the meaning and value behind the business model.</span><br><br><span style="color:rgb(0,0,0);">The reason for X To Earn being popular in Web3 lies in a new set of ideas it holds. In the traditional Web2 world, service providers need to expand and attract users through financing and “money-burning”, and after collecting user data, they then could improve the products. A clear barrier between service providers and users can be observed in this process. But in Web3, users are part of the community. They enter the project after purchasing NFT and hope to earn tokens through the "X" actions. They are longing for the maturity of the project and the profit gain from the token and NFTs trading. The attraction of X To Earn, thus, is not only the funds it brings to the project (obtained from the sale of NFTs), but also the role as a traffic portal to bring users with high centripetal force to the project, and the potential to turn them into solid community members for future applications.</span><br>&nbsp;</p><p>&nbsp;</p><div class="raw-html-embed"><h3 style="font-family: heebo; font-size: 20px;color: #2A3795;">How May You Find The Right “X”?</h3></div><p><span style="color:rgb(0,0,0);">As mentioned in the first article of this series, X To Earn is a popular business model on Web3. To develop your X To Earn project, you should first find the part of the existing business or new business that can shine in Web3, and second, extract the direction of X from your findings.&nbsp;</span><br><br><span style="color:rgb(0,0,0);">In this refining process, two elements of X must be kept in mind: quantification and satisfaction. Since the X involvement links to users' return, it is essential for this involvement to be easily quantified. Otherwise, the calculation of return will be quite difficult, and even have a huge impact on token issuance and the entire token economic system. On the other hand, if the quantitative mechanism of X is not well designed, it may be targeted by professional "gold diggers" to seize loopholes and cheat. As for satisfaction, it refers to the fun or contentment that the users can find while participating in X.&nbsp;</span><br><br><span style="color:rgb(0,0,0);">Imagine, if people are only focusing on X earning but not really into it, competitors can easily attract your clients by just offering higher returns. At that time, what more incentive can you adopt to keep the users?&nbsp;</span><br><br><span style="color:rgb(0,0,0);">Therefore, to carry out the X To Earn project, we must first find X, and then design a complete return mechanism and corresponding token economic system from the user perspective.</span><br>&nbsp;</p><p>&nbsp;</p><div class="raw-html-embed"><h3 style="font-family: heebo; font-size: 20px;color: #2A3795;">Pros And Cons Are The Key Factors Of The Success Of X To Earn Project</h3></div><p><span style="color:rgb(0,0,0);">As mentioned, the X To Earn project have a strong ability of attracting traffic, which can bring funds and users to the project. Under the attraction of "earning while X", the number of users can grow rapidly in the early stage of the project. Undoubtedly, this is one of the big advantages of the X To Earn project. However, one should note that X To Earn is still an emerging model, which requires the ability and determination to quickly correct after "trial and error".&nbsp;</span><br><br><span style="color:rgb(0,0,0);">Before launching the project, some preparations are needed. For example, the design of quantification and conversion mechanism, NFT issuance plan, tokenomics system planning, etc. All these items need to be comprehensively designed, and a certain amount of early capital investment is required. Before the X To Earn project carries out, it must be carefully and thoroughly planned. Otherwise, the funds may be exhausted due to mistakes in the early stage, or the development will be restricted due to improper arrangements. The early investors will be disappointed, eventually.</span></p><p>&nbsp;</p><p style="margin-left:0cm;text-align:center;"><strong>Based on the above three points, it can be seen that the development of the X2earn project requires forward-looking, planning, technology, execution, and correction capabilities.

<p>In the last article, we have listed different examples to demonstrate the diversity and possibility of X To Earn. But before going into details on how to integrate it into your business development, three key elements should be acknowledged and prepared to get a great start for your project.</p><p>&nbsp;</p><div class="raw-html-embed"><div style="text-align: center;">
<img src="https://static-asst.8338.hk/udhk-cms/haGX3KElbZQnPXKJaXS5.jpg" style=" width: 100%;max-width: 600px; height: auto;">
</div>
</div><div class="raw-html-embed"><h3 style="font-family: heebo; font-size: 20px;color: #2A3795;">NFT</h3></div><p>NFT, definitely, is one of the key elements. For instance, the props and weapons in the Play to Earn game, the sneakers in the Move to Earn project,&nbsp;<br>and the characters in the Learn to Earn program, are all NFT. The adoption of NFT, in fact, is based on two of its characteristics.<br><br>Firstly, the uniqueness of NFT. The non-fungible nature of NFT makes it a perfect digital credential, or an "identity card" in the Web 3 world. It can not only be used to identify the user's identity but also link the identity to the "wallet address" for income allocation. The second is scarcity. By controlling the rarity of issued NFTs, such as the level of game weapons, sneaker styles, etc., the project owner then can master the user's entry barrier and income level, or even develop a membership system. The NFT issuance plan, thus, determines the development direction of the X To Earn project.<br><br>&nbsp;</p><div class="raw-html-embed"><h3 style="font-family: heebo; font-size: 20px;color: #2A3795;">Token</h3></div><p>Needless to say, the word “earn” is the key icon that a X To Earn project catch people’s sight. The issuance of a token, in this case, is the most straightforward and convincing way to attract people, as it directly allows users to quantify their daily activities into tokens. Issuing tokens seems to be a one-off thing, however, it is not limited to minting new coins and sending them to users’ wallets but involves different levels of business planning. Say: whether to adopt a single-token model or a dual-token model that includes the “governance token” and “utility token”?&nbsp;<br><br>The former is relatively simple to design and manage, but the latter allows projects to have a bigger presence in the cryptocurrency market. The position of the token is worthy of attention. Should it be a coin that draws people’s attention with a huge market capitalization or a penny coin that brings people’s imagination of huge returns? If it is the former one, will it participate in decentralized finance (DeFi), and how to ensure the income of the validator? And if it is a penny coin, is there any strategy to attract users to continue to participate to earn coins? Also, if there will be an Auto-Burn mechanism? All these are the questions that need to be planned carefully before issuing coins or the technical problems, negative PR image are waiting ahead.&nbsp;<br>&nbsp;</p><div class="raw-html-embed"><h3 style="font-family: heebo; font-size: 20px;color: #2A3795;">Tokenomics</h3></div><p>If the issuance of tokens allows the users to experience the joy of earning, the tokenomics system, in this sense, is to design a complete field for them to spend "money". The importance of the tokenomics, however, is not only about sending the tokens to users available but also about the imagination it can bring to users&nbsp;<br>- will it be able to redeem the coupons of a big brand that can be used in the physical world? Or will it be possible to stake the tokens to earn more coins,&nbsp;in exchange for voting rights or participation in designated events? Or is it possible to use the token to buy NFTs and have different assets in the metaverse?

<p>MetaMask 是一个非常出名且最多人使用的 EVM (以太坊虚拟机器) 加密数字钱包，相信任何熟悉加密数字领域的人或多或少都有使用过 MetaMask 钱包。 然而，随着越来越多人进入加密数字领域，因此而衍生的数字骗案亦逐渐增多，而因为不熟悉区块链的运作模式，而导致的数字资产被盗的个案，则更是层出不穷。</p><p>曾经有朋友就发生过这样的情况，自己明明没有做任何交易，但发现自己钱包内的数字资产被无故转移，他确定助记词并没有洩露给他人，但自己曾多次使用该钱包登入不同网站，参与不同的 dApp 互动等，因此，非常有可能问题就出在签名上。<br><br>这次我们就以 MetaMask 为例，来说说关于<strong>区块链的三个签名问题</strong>。<br><br>所谓签名，实际上就是一个身份认证的过程。就如同你去银行提款，银行除了接收你的操作指示以外，还必不可少要进行身份认证，确保你是真正的账户拥有者。银行的身份认证可以是用密码，签名，印章等方式进行。</p><div class="raw-html-embed"><h3 style="font-family: heebo; font-size: 20px;color: #2A3795;">区块链签名</h3></div><p>区块链上的交易亦是如此， 当你进行一个交易时，除了要指示区块链「要做什麽」，还需要进行身份认证，确保你是真正的账户拥有者，才可进行相应操作。 这个身份认证，就是我们所说的「签名」。</p><p>签名的具体做法，是使用你保存在区块链钱包（如 MetaMask）中的私钥（Private Key）透过加密演算法，对你发出的指示做数字签署，而这个签署，是可以透过与你的地址公钥（Public Key）比对从而认证确实是你发出的相应指示，而完成认证过程。另外，「签名」这个动作，可以是不需要上链的。在没有网路的情况下亦可进行。</p><p><strong>因此，只要拥有一个有效的交易签名，配合对应的交易指令（例如转账），即可正常完成一次交易。</strong></p><p>说到这裡，相信聪明的读者都能够看出其中的玄机，在整个过程中交易签名是重中之重。换句话说，骗徒可以伪造一个交易，骗取你的交易签名，然后骗徒便可以凭藉这个签名，执行该伪造交易，从而导致你在莫名其妙的情况下，损失资产。而交易签名洩露，也就是许多数字资产被盗的元凶之一。</p><div class="raw-html-embed">

		<h2>EIP712 Sign</h2>
		<h3>一种更高级、更安全的交易签名方法</h3>
		<p class="table-content">EIP712 Sign是一种更安全的签名标准，这个标准规定了签名数据的结构，也加入了对数据的作用域限制，如 domain，验证合约地址等。</p>

		<p class="table-content">ERC712 签名经常会被用在执行 metatransaction 等合约执行中，例如 OpenSea NFT 上架，降低价格等过程都会出现 EIP712 签名请求。</p>

		<p class="table-content">这个标准的好处是，签名者可以清楚看到自己在签署的内容，很大程度上降低被钓鱼的风险。 但是，这并不等于这种签名是绝对安全的，签名时，一定要看清楚究竟在签署什么内容。

<p>MetaMask 是一個非常出名且最多人使用的 EVM (以太坊虛擬機器) 加密數字錢包，相信任何熟悉加密數字領域的人或多或少都有使用過 MetaMask 錢包。 然而，隨著越來越多人進入加密數字領域，因此而衍生的數字騙案亦逐漸增多，而因為不熟悉區塊鏈的運作模式，而導致的數字資產被盜的個案，則更是層出不窮。</p><p>曾經有朋友就發生過這樣的情況，自己明明沒有做任何交易，但發現自己錢包內的數字資產被無故轉移，他確定助記詞並沒有洩露給他人，但自己曾多次使用該錢包登入不同網站，參與不同的 dApp 互動等，因此，非常有可能問題就出在簽名上。<br><br>這次我們就以 MetaMask 為例，來說說關於<strong>區塊鏈的三個簽名問題</strong>。<br><br>所謂簽名，實際上就是一個身份認證的過程。就如同你去銀行提款，銀行除了接收你的操作指示以外，還必不可少要進行身份認證，確保你是真正的賬戶擁有者。銀行的身份認證可以是用密碼，簽名，印章等方式進行。</p><div class="raw-html-embed"><h3 style="font-family: heebo; font-size: 20px;color: #2A3795;">區塊鏈簽名</h3></div><p>區塊鏈上的交易亦是如此， 當你進行一個交易時，除了要指示區塊鏈「要做什麼」，還需要進行身份認證，確保你是真正的賬戶擁有者，才可進行相應操作。 這個身份認證，就是我們所說的「簽名」。</p><p>簽名的具體做法，是使用你保存在區塊鏈錢包（如 MetaMask）中的私鑰（Private Key）透過加密演算法，對你發出的指示做數字簽署，而這個簽署，是可以透過與你的地址公鑰（Public Key）比對從而認證確實是你發出的相應指示，而完成認證過程。另外，「簽名」這個動作，可以是不需要上鏈的。在沒有網路的情況下亦可進行。</p><p><strong>因此，只要擁有一個有效的交易簽名，配合對應的交易指令（例如轉賬），即可正常完成一次交易。</strong></p><p>說到這裡，相信聰明的讀者都能夠看出其中的玄機，在整個過程中交易簽名是重中之重。換句話說，騙徒可以偽造一個交易，騙取你的交易簽名，然後騙徒便可以憑藉這個簽名，執行該偽造交易，從而導致你在莫名其妙的情況下，損失資產。而交易簽名洩露，也就是許多數字資產被盜的元兇之一。</p><div class="raw-html-embed">

优仕对谈：Barley Nectar创办人Alistair MacDonald

<p><span style="color:rgb(0,0,0);">Traditional concepts have been subverted along with the popularity of blockchain, cryptocurrency, and Web 3. Among these concepts, X To Earn (x2earn) is an important one that cannot be ignore due to two facts. First, it redefines the way how the internet and the reality connect and reverses the dualistic imagination between reality and virtuality.
