区块链，就是一个又一个区块组成的链条。每一个区块中保存了一定的信息，它们按照各自产生的时间顺序连接成链条。这个链条被保存在所有的服务器中，只要整个系统中有一台服务器可以工作，整条区块链就是安全的。这些服务器在区块链系统中被称为节点，它们为整个区块链系统提供存储空间和算力支持。如果要修改区块链中的信息，必须征得半数以上节点的同意并修改所有节点中的信息，而这些节点通常掌握在不同的主体手中，因此篡改区块链中的信息是一件极其困难的事。相比于传统的网络，区块链具有两大核心特点：数据难以篡改和去中心化。基于这两个特点，区块链所记录的信息更加真实可靠，可以帮助解决人们互不信任的问题。

A blockchain is a chain of blocks. Each block holds a certain amount of information, which is linked in a chain according to the time sequence in which it was created. This chain is kept in all the servers, as long as one server in the whole system can work, the entire blockchain is safe. These servers, known as nodes in the blockchain system, provide storage space and computational power for the entire system. If you want to change the information in the blockchain, you have to get the consent of more than half of the nodes and change the information in all the nodes, and these nodes are usually in the hands of different subjects, so it's extremely difficult to tamper with the information in the blockchain. Compared with the traditional network, blockchain has two key characteristics: data is difficult to tamper with and decentralized. Based on these two characteristics, the information recorded by blockchain is more reliable and can help solve the problem of people's distrust.

区块链是一连串的区块。每个块保存一定数量的信息，这些信息根据创建它的时间顺序链接在一个链中。这个链是保持在所有的服务器，只要一个服务器在整个系统可以工作，整个区块链是安全的。这些服务器，被称为区块链系统中的节点，为整个系统提供存储空间和计算能力。如果你想改变区块链中的信息，你必须得到超过一半的节点的同意，改变所有节点中的信息，而这些节点通常掌握在不同的主体手中，因此篡改区块链中的信息是极其困难的。与传统的网络相比，区块链具有两个关键特征: 数据难以篡改和分散。基于这两个特征，区块链记录的信息更加可靠，可以帮助解决人们的不信任问题。

A blockchain is a series of blocks. Each block holds a certain amount of information that is linked in a chain according to the time in which it was created. This chain is kept on all servers as long as one server can work across the entire system and the entire blockchain is secure. These servers, known as nodes in a blockchain system, provide storage and computing power for the entire system. If you want to change the information in the blockchain, you have to get permission from more than half of the nodes to change the information in all the nodes, and these nodes are usually in the hands of different agents, so it's extremely difficult to tamper with the information in the blockchain. Compared with the traditional network, blockchain has two key characteristics: data is difficult to tamper with and scattered. Based on these two characteristics, the blockchain records more reliable information, can help solve the problem of people's distrust.

区块链是一系列的区块。每个块包含一定数量的信息，这些信息根据它被创建的时间链接在一起。这个链保持在所有服务器上，只要一个服务器可以工作在整个系统和整个区块链是安全的。这些服务器，被称为区块链系统中的节点，为整个系统提供存储和计算能力。如果你想改变区块链中的信息，你必须得到超过一半的节点的许可才能改变所有节点中的信息，而这些节点通常掌握在不同的代理人手中，因此篡改区块链中的信息是极其困难的。与传统网络相比，区块链具有数据难篡改和分散的特点。基于这两个特点，区块链记录更多可靠的信息，可以帮助解决人们的不信任问题。

A blockchain is a series of blocks. Each block contains a certain amount of information linked together according to the time it was created. This chain is maintained on all servers as long as one server can work safely throughout the system and the entire blockchain. These servers, known as nodes in a blockchain system, provide storage and computing power for the entire system. If you want to change the information in the blockchain, you have to get permission from more than half of the nodes to change the information in all the nodes, which are usually in the hands of different agents, so it's extremely difficult to tamper with the information in the blockchain.

Based on these two characteristics, blockchains record more reliable information, which can help solve the problem of people's distrust.

区块链是一系列的区块。每个块包含一定数量的信息，根据它被创建的时间链接在一起。只要一台服务器可以在整个系统和整个区块链中安全工作，这个链就可以在所有服务器上维护。这些服务器，被称为区块链系统中的节点，为整个系统提供存储和计算能力。如果你想改变区块链中的信息，你必须得到超过一半的节点的许可才能改变所有节点中的信息，而这些信息通常掌握在不同的代理人手中，因此篡改区块链中的信息是极其困难的。与传统的网络相比，区块链技术更难对数据进行篡改和分散。基于这两个特征，块环链记录了更多可靠的信息，有助于解决人们的不信任问题。

A blockchain is a series of blocks. Each block contains a certain amount of information, linked together according to the time it was created. As long as a single server can work safely across the system and across the blockchain, the chain can be maintained on all servers. These servers, known as nodes in a blockchain system, provide storage and computing power for the entire system. If you want to change the information in the blockchain, you have to get permission from more than half of the nodes to change the information in all the nodes, which is usually held by different agents, so it's extremely difficult to tamper with the information in the blockchain. Compared with the traditional network, blockchain technology is more difficult to tamper with and disperse the data. Based on these two characteristics, blockchain records more reliable information, which helps to solve the problem of people's distrust.

区块链是一系列的区块。每个块包含一定数量的信息，根据创建时间将它们链接在一起。只要一台服务器可以安全地跨系统和跨区块链工作，链可以在所有服务器上维护。这些服务器，被称为区块链系统中的节点，为整个系统提供存储和计算能力。如果你想改变区块链中的信息，你必须得到超过一半的节点的许可才能改变所有节点中的信息，这些信息通常由不同的代理人掌握，因此篡改区块链中的信息是极其困难的。与传统的网络相比，区块链技术更难以篡改和分散数据。基于这两个特征，区块链记录了更多可靠的信息，有助于解决人们的不信任问题。

区块链是一系列的区块。每个块包含一定数量的信息，根据创建时间连接在一起。只要一台服务器可以安全地跨系统和跨区块链工作，链可以在所有服务器上维护。这些服务器，被称为区块链系统中的节点，为整个系统提供存储和计算能力。如果你想改变区块链中的信息，你必须得到超过一半的节点的许可才能改变所有节点中的信息，这些信息通常由不同的代理人掌握，因此篡改区块链中的信息是极其困难的。与传统的网络相比，区块链技术更难于篡改和分散数据。基于这两个特征，区块链记录了更多可靠的信息，有助于解决人们的不信任问题。

A blockchain is a series of blocks. Each block contains a certain amount of information, wired together according to the time of creation. As long as one server can safely work across systems and across blockchains, chains can be maintained on all servers. These servers, known as nodes in a blockchain system, provide storage and computing power for the entire system. If you want to change the information in the blockchain, you have to get permission from more than half of the nodes to change the information in all the nodes, which is usually held by different agents, so it's extremely difficult to tamper with the information in the blockchain.

区块链是一系列的区块。每个块包含一定数量的信息，根据创建时间连接在一起。只要一台服务器可以安全地跨系统和跨区块链工作，链可以在所有服务器上维护。这些服务器，被称为区块链系统中的节点，为整个系统提供存储和计算能力。如果你想改变区块链中的信息，你必须得到超过一半的节点的许可才能改变所有节点中的信息，这些信息通常由不同的代理人掌握，因此篡改区块链中的信息是极其困难的。与传统的网络相比，区块链技术更难于篡改和分散数据。基于这两个特征，区块链记录了更多可靠的信息，有助于解决人们的不信任问题。

A blockchain is a series of blocks. Each block contains a certain amount of information, wired together according to the time of creation. As long as one server can safely work across systems and across blockchains, chains can be maintained on all servers. These servers, known as nodes in a blockchain system, provide storage and computing power for the entire system. If you want to change the information in the blockchain, you have to get permission from more than half of the nodes to change the information in all the nodes, which is usually held by different agents, so it's extremely difficult to tamper with the information in the blockchain.

区块链是一系列的区块。每个块包含一定数量的信息，根据创建时间连接在一起。只要一台服务器可以安全地跨系统和跨区块链工作，链可以在所有服务器上维护。这些服务器，被称为区块链系统中的节点，为整个系统提供存储和计算能力。如果你想改变区块链中的信息，你必须得到超过一半的节点的许可才能改变所有节点中的信息，这些信息通常由不同的代理人掌握，因此篡改区块链中的信息是极其困难的。与传统的网络相比，区块链技术更难于篡改和分散数据。基于这两个特征，区块链记录了更多可靠的信息，有助于解决人们的不信任问题。

A blockchain is a series of blocks. Each block contains a certain amount of information, wired together according to the time of creation. As long as one server can safely work across systems and across blockchains, chains can be maintained on all servers. These servers, known as nodes in a blockchain system, provide storage and computing power for the entire system. If you want to change the information in the blockchain, you have to get permission from more than half of the nodes to change the information in all the nodes, which is usually held by different agents, so it's extremely difficult to tamper with the information in the blockchain. Compared with traditional network, blockchain technology is more difficult to tamper with and disperse data. Based on these two characteristics, the blockchain records more reliable information, which helps to solve the problem of people's distrust.
