大家都在说，区块链是第三代互联网，价值互联网，为什么？
Everyone's saying the block chain is the third generation of the Internet, the value of the Internet. Why?
最早的网络是模拟通讯网络，主要是解决了电报的数字交流，电话的语音交流，传真的图像交流，但是视屏电话，始终由于模拟带宽的限制没有腾飞。这时候，还是只能进行相对简单的日常和工作信息交流。
The earliest networks are analogue communication networks, dealing mainly with cable digital exchanges, telephone voice exchanges, fax video exchanges, but video-screening telephones have never flown because of simulating bandwidth restrictions. At this point, the information exchange can only be relatively simple, day-to-day and work-related.
然后是数字通讯网络，同时实现了基于TCP／IP的包交换协议，从而有了今天无处不在的互联网和移动互联网。最早的互联网，也是只能进行一些静态信息的交流。之后，慢慢有了动态信息，交互式和实时读写。但是，大量的信息在网上移动，很多的都没有给生产者带来价值，而是给中间商带来了巨大的利润。Google，百度，采集和索引网上的内容，然后给用户提供查找服务，赚得盘满钵满，而内容的生产者并没有得到应有的价值回报。同理，Facebook，腾讯的社交网络。
Then the digital communication network, coupled with the TCP/IP-based package exchange protocol, has become the ubiquitous Internet and mobile Internet today. The earliest Internet, too, has only been able to communicate some static information.
于是，时代召唤第三代网络，价值互联网。这时，随着比特币在2009年的诞生，区块链作为后面的价值网络，应运而生。
So, the time calls for a third generation of networks, the value Internet. And then, with Bitcoin's birth in 2009, the block chain became the value network behind it.
价值的首要前提是需要确定资产的所有者。这就是区块链解决的第一个问题，确权。
The primary premise of value is the need to identify the owner of the asset. This is the first problem to be solved by the block chain.
首先，区块链应用密码学，利用公钥私钥机制，保障了只有通过私钥签名的资产才能使用唯一的公钥才能验证，那么，一个人只要用私钥对自己的资产签名，那么别的人就不能再声明对此资产的所有权了，而且也不能被窜改，因为别人没有他的私钥。那么，对于某个资产的签名，保证了某人对资产的唯一所有权，理论和算法上证明了。
First, block chains apply cryptography, using a public-key private key mechanism that secures the use of the only public key only if the asset is signed by a private key. If a person signs his own asset with a private key, then others can no longer declare ownership of the asset and cannot be tampered with, because others do not have his private key. So, for a signature of an asset, the sole ownership of the asset is guaranteed, both theoretically and arithmetically.
其次，区块链应用了分布式共识机制，保障了声明所有权的时间顺序，只有有了时间顺序，才有保障在同时有多人声明的情况下，第一个声明的人才是某资产的真正唯一拥有者。实现的机制是，先由一个节点收集在某一段时间内的声明顺序，然后由大量的其它节点来见证和验证，如果大部分节点都认可了，那么这个声明的顺序就被公认和确定了。有没有发现，还是基于的大多数认可的民主机制。
Secondly, the block chain applies a distributed consensus mechanism that guarantees the chronological order of the declaration of ownership, which guarantees that the first declaration is the true sole owner of an asset only if there is a chronological order. The mechanism is to collect the sequence of statements over a certain period of time by one node, then to be witnessed and validated by a large number of other nodes, and if most nodes are accepted, the order of the statement is recognized and established. Not found, or based on, most recognized democratic institutions.
最后，通过链式结构，加密哈希和分布式账本，保障了历史的所有权长期存在，不可更改。这些历史的所有权记录，是经过大部分群体认可的，所以是可信的。也就是说，当初声明的时候，大多数都听到了，见证了，想否认都不大可能了。
Finally, through chain structures, encryption of Hashi and distributional books, historical ownership is guaranteed for a long time and cannot be changed. The record of ownership of these histories, which is accepted by most groups, is credible. That is to say, most of the statements were heard, witnessed, and it was impossible to deny.
通过这些方式，区块链能够确权了，不可否认的确定谁拥有什么。那么，接下来需要解决价值的另一个前提是安全可靠的交换。价值是在供需中体现出来的，没有交换，就没有价值。区块链是如何解决可靠的交换的呢？
In these ways, the block chain can be authenticated and undeniably determine who owns what. Then another premise that needs to be addressed is a safe and secure exchange of values. Values are expressed in supply and demand, and there is no value without exchange. How does the block chain solve a reliable exchange?
首先，还是应用密码学，所有者通过提供签名验证才能释放自己的资产，转移给另外的人。另外的人拿到资产后，也只能通过自己私钥验证的签名才能将资产转移给别的人。这样，就保障了转移的一方确实拥有相应的资产。被转移的一方确实收到了相应的资产才能继续转移。这样，就保障了资产是所有者在交换。
First, it is cryptology that allows the owner to release his or her assets and transfer them to another person by providing a signature certification. Once another person has the assets, he or she can transfer them to another person only by means of a signature authenticated by his or her own private key. This guarantees that the transferring party does have the corresponding assets. The transferred party does receive the corresponding assets in order to continue the transfer.
其次，贯彻“Code is Law”的思想，采用脚本和智能合约的技术，保障交易只能在符合条件的情况下，才能真正发生。如果条件不能满足，那么相应的交易就会失败，等于什么都没有发生。这种自动化的交易机制，除了人，让机器和系统也能参与到交易中来。
Second, the idea of implementing & ldquo; Code is Law” using scripts and smart contract techniques that guarantee that transactions can actually take place only if they are qualified. If the conditions are not met, the corresponding transaction will fail and nothing will happen. This automated trading mechanism, apart from people, allows machines and systems to participate in the transaction.
再次，还是通过共识的机制给交易确定了顺序，从而解决了数字货币或是数字资产的“双花”问题。交易顺序一旦确定，同一笔资产，哪个交易先发生，哪个后发生，一目了然。这样，先发生的确定，后发生的就无效了，这样，保障了不会有双花发生。
And again, by establishing the order of transactions through a consensus mechanism, the question of &ldquao; & & & rdquao; digital money or & digital assets is resolved. Once the order of transactions is determined, which of the same assets first happens, which of them happens later, it becomes clear. So that the determination that occurs first, and then that happens, is invalid, so that there is no double flower.
最后，一个交易的确认，也是需要大多数的确认和共识，并且记录在案，不能更改。所有的历史交易都记录在案，随时可以查询。
Finally, the confirmation of a transaction requires a majority of confirmations and consensus and is recorded and cannot be changed.
有了“确权”和“交换”，价值就能完成了。而区块链正是解决了这两个问题，才成为了第三代互联网价值互联网的基石，让价值互联网成为可能和现实。
With & & & ldquo; & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & &, the value is done. And the block chain solves these two problems and becomes the cornerstone of the third generation of Internet value, making value Internet possible and real.
有了价值互联网，以后的想象空间就大了去了，这也是为啥各大公司，各个国家都不可忽视区块链技术和可能带来的变革。
With the value of the Internet, there will be more room for imagination later, and that is why large companies, countries cannot ignore the technology of block chains and the changes that may be brought about.
