Recently, the block chain and scraper fire. The central government should block chain as an important breakthrough in core technology innovation, increase investment, focus on breakthroughs in core technologies! Then the "block chain" in the end what is it? Many people initially through the "Bitcoin" and other virtual currency on the "block chain" some understanding, but do not know the big "block chain" in the end what's the use, etc., Xiao Bian today to introduce user-friendly next, for your reference.
First, what block chain?
Professional, the block chain (Blockchain) is a distributed data storage, new applications of computer technology point to point transmission mode, the consensus mechanism, encryption algorithms. Block chain is essentially a decentralized accounting system, is a new technology, its core is "decentralized."
Several central feature of the block chain
1, to the center
Block chain technology does not rely on additional third-party management or hardware, there is no central control, in addition to self-contained block chain itself, through distributed storage and accounting, information on each node to achieve a self-validation, delivery and management. To the center is the most prominent feature of most essential block chain.
2, very safe
As long as no control over 51% of all data node, you can not modify the network wanton manipulation of data, which makes the block chain itself becomes relatively safe, avoiding the subjective human data changes. And centralized databases, the attacker does not have a single point of entry, data security more secure, it also makes the block chain technology is very safe.
3, non-tamper resistance
Once inside the block chain, any information can not be changed, even the administrator can not modify this information. Once it is no longer a thing can not be changed, this property is currently enjoying for human beings can change, ever-changing online world in terms of great significance.
4, open
Block chain technology is based on open source, in addition to private information outside of the parties to the transaction is encrypted data block chain is open to everyone, anyone can through open interfaces and data query block chain and develop its application, the entire highly transparent information system, all nodes in the network can easily access information.
5, no third party
Because the chain to the center of the block, it can help point the transaction, therefore, whether you are in the trading or exchange funds, all without the approval of a third party.
6, anonymity
区块链本身就是一个平台,除非有法律规范要求,单从技术上来讲,各区块节点的身份信息不需要公开或验证,信息传递可以匿名进行 。
二、区块链与比特币的关系
说到区块链,很多小伙伴目前第一时间会想到比特币,之前伴随着比特币的火爆,就连不少大妈都在讨论区块链,众多科技公司也都纷纷布局区块链。那么,区块链和比特币是什么关系呢?
区块链,是比特币的一个重要概念,它本质上是一个去中心化的数据库,同时作为比特币的底层技术,是一串使用密码学方法相关联产生的数据”
比特币是世界上第一个用区块链技术做的虚拟币,也是目前基于区块链技术最火的一种虚拟货币,它的目标是其整体币值对标整个世界的财富估值。
但是需要注意的是,区块链并不等于虚拟币,它只是基于区块链技术的一种,区块链的范畴远比比特币要大,因此,比特别并不等于区块链。比如,苹果比作是比特币的话,区块链则是水果,我们可以说苹果是一种水果,但水果有很多,就不一定是指苹果了,简单来说,比特币是第一个基于区块链技术打造的爆款产品。
所以区块链实际上是一种新技术,而不仅仅是之前一地鸡毛的各种虚拟货币,绝非是炒币!虚拟货币只是区块链的一种应用,而且还是被国家严打的那种…。
三、通俗易懂解释区块链
区块链作为一项比较高深的新技术,看概念很多人还是很难理解,下面通过一些通俗易懂的术语帮助大家大概懂个皮毛吧。
区块链本质上市一个去中心化的数据库,一个去中心化的分布式储存带来公开与透明,也让数据直接产生价值;信息的不可篡改、可追溯性带来了安全与诚实,也让人与人之间变得更加互信。
下面首先来看看中央政法委公众号上分享的一些区块链应用的解读:
1、民生领域
把个人信息上传到区块链,将受到加密保护,对信息的伪造冒用都能被识别出来,个人信息安全不再是一个让人担心的问题,让共享变得更加可行:教育、就业、养老、精准脱贫、医疗健康、商品防伪、食品安全、公益、社会救助等等方面,都因此能给人们带来更加智能、更加便捷、更加优质的服务。
2、经济产业领域
企业把各类信息上传到区块链上,可以让整个产业链变得更加透明:企业可以精准掌握市场需求,调整供给,深化供给侧改革;金融机构可以在征信方面节约大量的成本,放心地向企业、个人提供贷款、保险等金融服务,解决中小企业融资难的问题;贸易领域可以省略大量的纸面工作,监控物流环节,防止中间欺诈的发生。
3、政务领域
各部门各系统之间的信息壁垒会完全打通,不再是一个个信息孤岛,政务数据跨部门、跨区域共同维护和利用,促进业务协同办理,这不仅让政务变得更加公开,还将把让群众“最多跑一次”的口号,变为大家习以为常的惯例。
区块链应用场景还有很多,以上仅仅是官媒解读的很小部分,还有包括诸多场景,如:
4、数字身份
很多人开各种证明时会遇到“证明我妈是我妈”的窘境,有了区块链,就再也不用担心了。原来我们的出生证、房产证、婚姻证等等,需要一个中心节点,大家才能承认。一旦跨国,合同和证书可能就失效了,因为缺少全球性的中心节点。
区块链技术不可篡改的特性从根本上改变了这一情况,我们的出生证、房产证、婚姻证都可以在区块链上公证,变成全球都信任的东西,当然也可以轻松证明 “我妈是我妈”。
5、卫生保健
简单说就是利用区块链建立有时间戳的通用记录存储库,进而达到不同数据库都可提取数据信息的目的。例如你去看病,不用换个医院就反复检查,也不用为报销医保反复折腾,可以节省时间和开销。
6、旅行消费
例如我们经常会用携程、美团等app来寻找并下单入住酒店和其他服务,各个平台从中获得提成。而区块链的应用正是除去中间商,并为服务提供商和客户创建安全、分散的方式,以达到直接进行连接和交易的目的。
7、更便捷的交易
区块链可以让支付和交易变得更高效、更便捷。区块链平台允许用户创建在满足某些条件时变为活动的智能合约,这意味着当交易双方同意满足其条件时,可以释放自动付款。
8、严把产品质量关
假如你买了一个苹果,在区块链技术下,你可以知道从果农的生产到流通环节的全过程。在这其中有政府的监管信息、有专业的检测数据、有企业的质量检验数据等等。智慧的供应链将使我们日常吃到的食物、用到的商品更加安全,让我们更加放心。
9、产权保护艺术
创作者把自己的作品放在区块链上,有人使用了他的作品,他就能立刻知道。相应的版税也会自动支付给创作者。区块链技术既保护了版权,也有助于创作者更好更直接地向消费者售卖自己的作品,而不再需要发行公司的协助。
10、金融领域
众所周知,金融的核心是“信用”体系。谁能解决信用问题,谁就占据了金融的高地。 在传统金融领域,光在信用问题上,就产生了大量的担保、增信机构。比如银行、担保、信托、支付等。
再比如,马爸爸为了大家在淘宝买东西更放心为初心开发的余额宝。所以,区块链的最大想象力在于颠覆现有的金融体系,并且端倪明显。当然,区块链还能解决诚信问题,可以颠覆各种“中介”场景,省去了中间环节,想象前景还是很大的。
…
总之,区块链是一项核心技术,它绝非炒币。近几年,区块链在跨境支付等方面进展迅速,它甚至有了改变美元世界霸权的可能性。
四、区块链通俗易懂举例与漫画解读
举几个栗子:
打个比方:男孩给女孩说了一句“我爱你一生一世”,然后女孩把这句话发给了闺蜜、爸妈、朋友圈、公众号、微信群,于是男孩再也无法抵赖。
再比如:某某村,翠花跟隔壁老王偷情,被张三看见了。之后,张三把这个事告诉了村里所有人。于是,翠花和老王道关于偷情这件事,路人皆知。
在这件事的舆论风波中,张三是一个中心。所有的信息,都是通过张三往外传播的。但这里就带来几个问题:
1、张三的诚信问题。存在张三喜欢翠花,但翠花不搭理张三,然后张三恶意报复的可能。
2、传播过程中,故事被添盐加醋。
Joe Smith told Zhangma time, is having an affair. Zhang Ma told John Doe point when, in order wonderful, into a cohabitation. John Doe told the neighboring village money seven times, recently added the Cuihua convex tummy, back with his wife talked about the money seven times, on Cuihua pregnant ...... Finally, the entire county are circulating stories and became Cuihua Pharaoh, already we have a 6-year-old son ......
If it is added to the center of the element is kind of how?
Gave kidnapper village everyone has a real-time synchronization, video player and automatic backups. Assuming Cuihua affair with Pharaoh, the terminal camera live coverage of this player. Then everyone in the village at the same time to see live video ......
This is not the most peculiar, even more peculiar is that each video player have been automatic backup, Cuihua want to delete this video, you must convince everyone ......
This time, when there is no center of moral hazard that point, there was no information dissemination of aliasing. So, go to the center of the billing system, the nature of higher order to solve the credit problem.
Finally, attach a more fire online comic on the "block chain" explained together under appreciation.
In short, the block chain may be a revolutionary technology comparable to 5G, the biggest feature is decentralized, to address the root causes of most of the issue of trust, or will change our lives in the future to a large extent. Credit can be said is the cornerstone of human civilization, the nature of credit, is the store of value, the highest level of credit societies. When the case we will interfere with each other less and less, people will be able to truly move toward independence and equality
