Blockchain Technology Overview

区块链技术综述

在我们研究最好的区块链教程之前，让我们先从一般术语中了解区块链技术。继续阅读，你将看到这项技术实际上是什么以及它给用户带来了什么价值。

Blockchain is a network of records (a.k.a. blocks), which find storage on different PCs across the globe, link to each other and are secured with cryptography. There are millions of computers that store the records of the blockchain database. The blocks reconcile every 10 minutes, providing for autonomy and incorruptibility of the chain. What’s more, the nodes distribute the data of the blockchain in the way that many computers store a single transaction. That’s why no single person can modify the data.

区块链是一个记录网络(又名块)，它在全球不同的PC上找到存储，彼此链接，并使用加密技术进行保护。有数百万台计算机存储区块链数据库的记录。每隔10分钟就有区块进行协调，以保证链的自主性和廉洁性。更重要的是，节点以许多计算机存储单个事务的方式分配区块链的数据。这就是为什么没有人可以修改数据。

Blockchain Structure

The blockchain has a linear structure. Each block connects to the previous one by the means of a hash pointer. So, if you follow these connections, you’ll eventually end up uncovering the genesis block, which is the first block of the blockchain. Modern blockchains are vast and contain billions of transactions. Some of them get a new block every 3 to 5 seconds. That’s why in 2017, the size of a single developed blockchain was more than 100Gb. However, thanks to decentralization, the data are distributed in the way that all the transactions are publicly accessible and interconnected.

区块链结构

区块链具有线性结构。每个块通过哈希指针连接到前一个块。因此，如果遵循这些连接，最终将发现成因块，这是块链的第一个块。现代区块链庞大，包含数十亿笔交易。其中一些人每隔3到5秒就会得到一个新的块。这就是为什么在2017，一个单一的开发区块链的大小超过100 Gb。然而，由于权力下放，数据的分布方式是所有交易都是公开的和相互联系的。

This being said, the employment of blockchain technology brings a number of advantages to people using it. We enumerate the major ones of them below:

尽管如此，区块链技术的应用还是给使用它的人带来了许多好处。我们列举其中的主要问题如下：

First of all, there’s no power or authority governing the blockchain. That’s why there’s no fee you pay for verifying and auditing transactions. What’s more, blockchain transactions are not only cheaper but also quicker.

首先，没有权力或权威来管理区块链。这就是为什么你不需要为验证和审计交易支付任何费用。更重要的是，区块链交易不仅更便宜，而且更快。

Secondly, there’s hardly a more secure value exchange technology than blockchain. Each chain node stores just a part of the database. The blockchain replicates this part of the database a number of times across the network of nodes. As a result, there’s no hierarchy, and no central points, vulnerable to cyber-attacks. What’s more, even a single blockchain transaction can’t be modified retrospectively. The blockchain tracks such a violation immediately, as this violation leads to changes in all the subsequent chain blocks.

其次，没有比区块链更安全的价值交换技术了。每个链节点只存储数据库的一部分。块链在节点网络中多次复制数据库的这一部分。因此，没有等级制度，也没有中心点，容易受到网络攻击。更重要的是，即使是单一的区块链交易也不能追溯到过去。区块链会立即跟踪这样的违规行为，因为这种违规会导致所有后续链块的更改。

Next, the blockchain is public and open. Basically, any party or person can join the blockchain and access the needed transactions. So, being equally accessible to all people all over the globe, the blockchain ensures that no group of people gets more power than others in the blockchain.

接下来，区块链是开源和开放的。基本上，任何一方或个人都可以加入区块链并访问所需的事务。因此，由于世界各地的人都能平等地使用，区块链确保没有一群人比其他人在区块链中获得更多的权力。

Applications of Blockchain Theory

Given these points, the possible applications of blockchain technology are not limited to cryptocurrency trade. For example, the blockchain technology powers smart contracts, i.e. the contracts that are automatically authorized and undisputed. Smart contracts already find their application in land registration and music industry. Moreover, blockchains effectively simplify medical record management, identity management, online voting, and tracking digital use of copyright materials. Even the giant payment systems, such as VISA, Mastercard, SWIFT, and UnionPay, are already devising the schema of future incorporation of blockchain technology on the global scale.

区块链理论的应用

鉴于这些点，区块链技术的可能应用并不局限于密码货币交易。例如，区块链技术授权智能合约，即自动授权和无可争议的合约，智能合约已经在土地登记和音乐产业中得到了应用。此外，区块链有效地简化了病历管理、身份管理、在线投票和跟踪版权材料的数字使用。即使是诸如Visa、Mastercard、Swift和UnionPay这样的巨型支付系统，也已经在设计未来在全球范围内整合区块链技术的方案。

This being said, mastering blockchain today is a sound investment into the future for a web developer. Fortunately, there’s a number of blockchain tutorials that you can access on the net free of charge or for a moderate price. Let’s review the best blockchain tutorials and guides 2018, so that you know the ways to master how does blockchain work and how to work with this technology.

尽管如此，掌握如今的区块链对于一个web开发人员来说是对未来的一项合理的投资。幸运的是，有许多区块链教程，你可以在网上免费或以适度的价格访问。让我们回顾一下最佳区块链教程和指南2018年，以便你了解如何掌握区块链如何工作以及如何使用此技术。

Blockchain Tutorial: Creating Your Own Cryptocurrency With Ethereum

If you’ve coped with the greeter exercise, the next step is to power your own cryptocurrency. Sounds exciting, doesn’t it? Let’s see what you’ll have to do to be proud of having your own cryptocurrency.

区块链教程：使用以太坊创建自己的加密货币

如果你已经完成了“接入”练习，下一步就是为你自己的加密货币提供电源。这听起来很刺激，不是吗？那就让我们看看你要再做什么，才能为自己创造的密码货币而感到骄傲。

The ‘Create your own Cryptocurrency’ tutorial will guide you through powering your own digital token (for example, coins, loyalty points, gold certificates, IOUs), which is compatible with the Ethereum wallet. To create it, you have to complete a number of steps.

“创建自己的加密货币教程将指导你通过为自己的数字令牌(例如硬币，忠诚度点，金牌证书，借条)提供动力，这是与以太坊钱包兼容的。要创建它，你还必须要完成许多步骤。

First of all, you have to deploy a new contract in your Ethereum wallet and add the provided token source code. Secondly, you should do a number of listed code manipulations to make your code work the right way. Thirdly, you have to compile the code. Now, you can share your token with your friends and use it as an exchange value inside the group of people who have them. However, the real magic starts once you add custom functions to the token. As a result, your token starts acquiring value. You’ll find the functions listed and explained in the tutorial. The next sections of this tutorial instruct you on deploying and using your coin. Don’t miss a single step if you really want it to work and gain value over time!All in all, this is a great practical tutorial that lets you tap into doing amazing thighs with blockchain technology. Be meticulous in following it, and you’ll see that the magic happens in front of your eyes.
