In today's article, we will be discussing five block chain interview questions, but before we do that, just a quick disclaimer, these questions are not guaranteed to be asked at your interview. I pulled all today's questions and answers from our website. Now let's get started. Question number one, can you explain in general terms what bar chain is? This is an opening question which interviewer will use to start the conversation, learn more about your background and collect Information they can use throughout interview.

在今天的文章中，我们将讨论五个区块链面试问题，但在此之前，只需简短地声明一下，这些问题并不保证会在面试中被问到。我从我们的网站上下载了今天所有的问题和答案。现在让我们开始吧。第一个问题，你能概括地解释一下什么是酒吧连锁吗？这是一个开场问题，面试官将用它来开始谈话，更多地了解你的背景，并收集他们在整个面试过程中可以使用的信息。

This question also provides you the opportunity to direct the interview towards subject areas that you are comfortable discussing. A watching is a record and ledger format that records transactions. The union characteristic is that it is decentralized and is distributed across many individual databases as a flat file. This distribution model is what makes block chain records secure. Question number two, what is an individual block in a block chain? And how do you recognize it? You can recognize this question as being technical because it asked about a specific term or feature of the block chain. Keep in mind that your answers to technical questions should be briefed into the point, allowing the interviewers ask follow up questions if they need additional Information. An individual block within a Boxing is simply a record that contains data. These records really to each other through an encrypted communications channel. Books are mutable and cannot be changed once they are written. Blocks are identified based on their height and header hash. The computerized algorithm known as a hash function is used to identify individual blocks. The blocks are stored and distributed flat file databases across many different computing platforms.

这个问题也为你提供了一个机会，让你把面试引向你愿意讨论的主题领域。监视是一种记录交易的记录和分类帐格式。UNION的特点是它是分散的，并且作为一个平面文件分布在许多单独的数据库中。这种分发模式使区块链记录变得安全。第二个问题，什么是区块链中的单个区块？你是怎么认出它的？你可以认为这个问题是技术性的，因为它问的是区块链的一个特定术语或特征。请记住，你对技术问题的回答应该简明扼要，允许面试官在需要额外信息时提出后续问题。装箱中的单个块只是一个包含数据的记录。这些记录实际上是通过加密的通信渠道相互传递的。书是易变的，一旦写好就不能改变。块是根据其高度和标头哈希来标识的。被称为哈希函数的计算机化算法用于识别各个块。这些块存储在平面文件数据库中，并分布在许多不同的计算平台上。

Question number three, can you break down the block chain architecture into its core components? The interview will repeatedly test your knowledge about watching throughout interview. It is best to brush up on core concepts of block chain. Before your interview begins, the block chains, core components start with a node, which is the user and a computer system at the edge of the block chain. The next component is a transaction. Transactions, are the smallest component of the block chain. A block within the block chain is a ledger that is used to store Information about individual transactions. Lots are distributed across the block chain network and maintain by each node or user. The chain is just a sequence of blocks within the block chain. The next component is the miners. These are specific nodes are thereby transactions before they are added to the block chain structure. The final component of a block chain is a consensus protocol. The c terms, the rules used to carry out each block chain operation.

第三个问题，你能把区块链架构分解成核心组件吗？面试将反复测试你在整个面试过程中对观看的了解。最好是温习一下区块链的核心概念。在你的面试开始之前，区块链，核心组件从一个节点开始，这个节点是用户和区块链边缘的计算机系统。下一个组件是事务。交易，是区块链最小的组成部分。区块链中的区块是用于存储个人交易信息的账本。LOTS分布在整个区块链网络中，并由每个节点或用户维护。链只是区块链内部的一个区块序列。下一个组成部分是矿工。这些是特定的节点，因此在它们被添加到区块链结构之前是交易。区块链的最终组成部分是共识协议。C术语，用于执行每个区块链操作的规则。

Question number four, what role does encryption play in a block chain? As interview progresses, you'll continue to be as a variety of different types of questions. These include general, technical, operational, behavioral, situational and cultural questions. There's no set pattern interviewers use for these. However, you can anticipate that the questions will become more difficult in the middle and the end of the interview. This indicates that the interviewer is gaining confidence in your capabilities and is willing to export qualifications in more detail. This technical question is an example of. This encryption is one of the methods used to secure the data within a block chain. When encryption works is to encrypt the data and create a key using the corruption. The data is then transmitted in an encrypted format, which makes it impossible to read or decipher. The key use to encrypt the data is provided to the receiving party to decrypt and read the data.

第四个问题，加密在区块链中扮演什么角色？随着面试的进行，你会继续被问到各种不同类型的问题。这些问题包括一般问题、技术问题、操作问题、行为问题、情景问题和文化问题。面试官对这些没有固定的模式。然而，你可以预料到，在面试的中间和最后，问题会变得更难。这表明面试官对你的能力越来越有信心，并愿意更详细地介绍你的资历。这个技术问题就是一个例子。这种加密是用于保护区块链内数据的方法之一。当加密工作是加密数据，并创建一个密钥使用腐败。然后，数据以加密格式传输，使其无法读取或破译。用于加密数据的密钥被提供给接收方以解密和读取数据。

Question number five, why do you feel block chain is a trusted approach to financial transactions? Appears that the question asked for an opinion. The interviewer is looking for you to say facts and the rationale behind the light block chains are secure. When ask, for my opinion, you can feel Free to do so as long as well grounded in factual data. Any opinion you provide should also align with those of the organization with whom you are interviewing for. There are several different reasons why block chain is a trusted approach to financial transactions. These included being open source and therefore compatible with other business applications. The fact that it is transparent and secure due to its distributed nature. Block chains improve the efficiency and speed transactions, and they are hackproof based on the fact that there is no central authority that controls them.

第五个问题，为什么你觉得区块链是一种值得信赖的金融交易方式？看来这个问题是在征求意见。面试官希望你说出事实，以及光区块链背后的基本原理是安全的。当被问到我的意见时，只要有充分的事实数据，你就可以自由地这样做。你提供的任何意见也应该与你面试的组织的意见保持一致。区块链之所以是一种可信的金融交易方式，有几个不同的原因。其中包括开源，因此与其他业务应用程序兼容。由于其分布式特性，它是透明和安全的。区块链提高了交易的效率和速度，并且基于没有中央机构控制它们的事实，它们是防黑客的。
