How will blockchain technology change the world?
区块链技术将如何改变世界？
“Blockchain technology distributed across multiple data centers can ensure security against attacks on important network and hardware equipment.”
“分布在多个数据中心的区块链可以确保数据安全，防止重要网络和硬件设备的攻击带来的破坏。”
Everyday your hear about Blockchain technology, Bitcoin, ICO, Ethereum but do you understand how will blockchain change the world?
您每天都会听到区块链技术，比特币，ICO，以太坊，但您知道区块链将如何改变世界吗？
The Blockchain is a technology based on the virtual digitized decentralized network with “blocks” of information. When you add any information in the network (e. g. transaction), you add it in all computers in the network.
区块链由无数基于虚拟数字化分布式网络技术的“区块”组成，你在区块链中添加任何信息（例如，一笔交易）时，这些信息会被同时添加到所有的区块中，也就是所有计算机中。
But if another user in this network adds his information and make a new block after yours, you can’t modify your block. However, you can edit your block if you make it editing from all computers in the network and make similar changes in one moment only. It makes Blockchain one of the best technology for saving and structure information.
如果其他用户在你之后添加了新的区块，你就不能再修改你的区块了，但你可以在全网范围内编辑你的区块信息，而这些操作都是在一瞬间就可以完成，这就使得区块链成为存储交易信息的最佳技术选择。
Blockchain advantages:
区块链优势：
1.Security of data and transactions
数据和交易的安全性
2.Safe data storage and exchange
安全的数据存储和交换
3.There is no central authority or a single administrator
去中心化、去单一管理
4.There is no intermediaries (banks, financial institutions, etc.). transactions are direct
没有中介机构（银行，金融机构等），点对点直接交易
5.Each network participant has access to data
每个网络参与者都可以访问数据
6.It can be applied in many situations and solve a wide range of tasks.
它可以应用于很多情况并完成各种各样的任务。
Blockchain has the ability to increase secure data exchange in other industries as well. It also has the ability to make that data transfer simpler and easier between entities.
区块链还能够增加其他行业数据交换的安全性，能够使实体之间的数据传输更简单，更容易。
Healthcare: Using digital signatures on blockchain-based data that allows access only when authorized by multiple people could regulate the availability and maintain the privacy of health records. In addition, a community of people, including hospitals, doctors, patients, and insurance companies, could be part of the overall blockchain, reducing fraud in healthcare payments.
医疗健康：在基于区块链的数据上使用数字签名，只有在多人授权的情况下才允许访问，这可以控制数据的可用性并维护健康记录的隐私。此外，包括医院，医生，患者和保险公司在内的人群可以成为整个区块链的一部分，从而减少医疗保健支付中的欺诈行为。
Defense: Unauthorized access or modification of critical defense infrastructure, such as operating systems and network firmware, could seriously compromise national security. For most countries, defense infrastructure and computer systems are distributed across different locations. Blockchain technology distributed across multiple data centers can ensure security against attacks on important network and hardware equipment by ensuring consensus-based access for modification.
国防建设：未经授权访问或修改关键防御基础设施（如操作系统和网络固件）会严重危害国家安全。而对于大多数国家而言，国防基础设施和计算机网络系统分布在不同地方。分布在多个数据中心的区块链可确保通过确保访问和修改基于共识，共同抵御对重要网络和硬件设备的攻击。
Government: Government departments that work in silos cause the exchange of information to be delayed, negatively impacting citizen services. Linking the data between the departments with blockchain ensures that data is released in real time, when both the departments and the citizen consent to sharing data. Blockchain technology could improve transparency and check corruption in governments worldwide.
政府：政府部门孤立工作会导致信息交流延迟，给公民服务带来负面影响，使用区块链技术可以将各个政府部门以及公民连接起来共享数据和实时发布信息。区块链技术可以提高全球范围内政府的透明度和反腐败力度。
Law: Blockchains can contain a huge amount of data, including entire contracts. The impact of “smart contracts”—protocols that facilitate or enforce contract performance using blockchain—will have a profound impact for industries. Smart contracts eliminate the middleman. By its very nature, the smart contract is easily enforceable electronically, creating a powerful escrow by taking it out of the control of a single party.
法律事务：区块链可以存储大量数据，包括整个合约信息。“智能合约”可以很好地促进合约双方履行协议，这将对整个行业产生深远影响。智能合约消除了中间人，例如律师事务所。就其本质而言，智能合约可以通过电子方式轻松实现，通过将其从一方的控制中独立出来创建一个无比强大的托管服务。
Energy: Smart meters can register produced and consumed electricity in a blockchain, which allows for consumption of the surplus energy in a different location, providing credits or currency to the original producer. The credits can then be redeemed against the grid when the microgenerator needs additional electricity from the grid. The blockchain enforces these contracts in real time or near-real time, allowing for a utility market to be created with minimal red tape.
能源：智能电表可以在区块链中记录生产和消耗的电力，在不同的地方分配剩余能源，为原始生产者提供信用或货币。然后，当微型发电机需要来自电网的额外电力时，又可以将信用兑换成电网。区块链实时或接近实时地执行这些合约，会最大化减少最少社会公共舍业的繁文缛节。
With such wide-ranging possibilities, there is no surprise that blockchain has the potential to enhance the quality of service delivery while improving confidentiality and integrity of data. With its promise of providing secure and transparent transactions, blockchain seems poised to be one of the digital world’s key pillars
区块链可以提高服务质量，提高数据的机密性和完整性，具有如此广泛的应用。凭借其提供安全和透明交易的承诺，区块链似乎有望成为数字世界的重要支柱之一。
