说道区块链，相信大家都了解，区块链是比特币最底层的技术，提到区块链就不得不提到区块链节点，在区块链网络中有三种类型的节点，它们在网络中提供不同的功能，这些节点类型为，广播节点: 它们只发出事务并接收来自第三方的区块链信息。它们遵循最强大的采矿动力，被称为轻钱包，广泛应用于移动设备，或者仅仅被不想下载整个区块链的人使用。完整节点:安装完整的节点软件，如Bitcoin Core，除了拥有最安全的钱包，还会下载区块链的一个副本，成为比特币网络中的一个节点。接下来，币圈子小编就通俗的跟大家讲解区块链节点是什么？以及区块链节点的基本原理。
Speaking of block chains, everyone knows that block chains are the bottom of Bitcoin's technology, and referring to block chains makes it necessary to refer to block chain nodes, which have three types of nodes in the block chain network, which provide different functions in the network, which are broadcast nodes: they only send affairs and receive information from third parties. They follow the most powerful mining dynamics, known as light wallets, which are widely used in mobile devices or only by those who do not want to download the entire block chain. Full node: install complete node software, such as Bitcoin Core, which, in addition to having the safest wallet, downloads a copy of the block node to become a node in the Bitconet network.
区块链节点，通常是指下载了相关加密货币(比特币、Ethereum、Monero等)软件，以参与对等网络的计算机。
Block chain nodes are usually computers that download relevant encrypted currency (bitcoin, Etherum, Monero, etc.) software to participate in the peer network.
加密货币区块链的结构是对等点(P2P)之间的网络架构。P2P是指参与网络的计算机彼此相等。P2P这个词并不新鲜，P2P网络的第一次大规模使用是由音乐文件共享网络Napster完成的。
The structure of the encrypted currency block chain is the network structure between the equal points (P2P). P2P refers to the equivalent of the computers involved in the network. The term P2P is not new, and the first large-scale use of the P2P network was made by the music file sharing network Napster.
虽然Napster网络一点也不复杂(只是一个文件共享协议)，但与现在的区块链网络相比，它的基本原理是一样的。从这个意义上说，最古老的P2P网络，类似于当前区块链的工作，是SETI @ HOME网络。SETI @ HOME是一个计算机网络，由SETI创建，用于分析世界各地射电望远镜的数据，分析来自射电望远镜的数据，寻找银河系中的智能生命。人们想要参与这个网络，只需从它的官方网站下载软件并执行即可。
Although the Napster network is not complex (a document-sharing agreement), it is based on the same rationale as the current block-chain network. In this sense, the oldest P2P network, similar to the current block-chain, is SETI @HOME network. SETI @HOME is a computer network created by SETI to analyse data from radio telescopes around the world, analyse data from radio telescopes, and look for intelligent life in the galaxy. People want to participate in the network by downloading the software and implementing it from its official website.
这样，在P2P网络中，参与网络的每一台计算机都可以接收节点的名称。在网络中，所有的节点都有责任提供网络服务。这是因为网络节点的互连性，允许进行互操作性。
In this way, every computer participating in the network can receive the name of the node in the P2P network. In the network, all nodes are responsible for providing network services. This is because of the interconnectivity of the network node, which allows interoperability.
区块链网络是指执行给定区块链P2P协议的节点集。整个网络以完全联合、去中心化和分布式的方式编排和协调每个用户在网络中所做的操作。这意味着全世界的计算机网络可以不断地相互传输新的事务。这个网络中的每台计算机都是一个节点，它已经下载了完整的区块链。这样，网络就变得冗余了，而协同工作使其在扩展方面具有可伸缩性。
Block chain networks are nodes for the implementation of the P2P protocol for the given block chain. The entire network is organized and coordinated in a fully integrated, decentralised and distributed way for each user to perform the operation in the network. This means that computer networks around the world can transmit new matters to each other on a continuous basis. Each computer in this network is a node and it has downloaded the entire block chain. In this way, the network becomes redundant, and collaborative work makes it scalable in terms of expansion.
由于区块链的分散化，任何人都可以参与其中。只需从下载节点软件并执行它即可。通常，每个项目的主钱包都支持此功能。最初，网络从区块链的起源开始，直到与网络同步为止。此时，节点开始全面运行，不仅允许验证事务，而且支持区块链的整体映像。通常节点可以执行以下功能:路由、区块链数据库、挖掘和钱包服务。
As a result of the fragmentation of the block chain, anyone can participate. You can simply download node software and execute it. Usually, the main wallet of each project supports this function. Initially, the network starts from the origin of the block chain until it is synchronized with the network. At this point, the node is fully operational, allowing not only validation services, but also supporting the overall image of the block chain.
这些节点是一个区块链最大数据结构中的单个部分。当节点所有者自愿贡献自己的计算资源来存储和验证事务时，他们就有机会收取交易费用，并在潜在的加密货币中获得奖励。
These nodes are a single part of the largest data structure of the block chain. When node owners voluntarily contribute their computing resources to the storage and validation services, they have the opportunity to charge transaction costs and receive incentives for potential encrypted currency.
处理这些事务可能需要大量的计算和处理能力，这意味着计算机的平均能力是不够的。一般来说，专业的矿商倾向于投资被称为CPU(中央处理单元)或GPU(图形处理单元)的非常强大的计算设备，以满足对验证事务所需的处理能力的需求，从而获得相应的回报。
Dealing with these services may require a great deal of computing and processing capacity, which means that the average computer capacity is not enough. Generally speaking, professional miners tend to invest in very powerful computing equipment, known as CPU (central processing unit) or GPU ( graphic processing unit), to meet the demand for processing capacity required for certification services, thereby yielding corresponding returns.
节点可以是通信端点，也可以是通信的重分发点，链接到其他节点。网络中的每个节点都被认为是相等的，但是，某些节点在支持网络的方式上扮演着不同的角色。例如，并非所有节点都会存储区块链的完整副本。
Nodes can be either a communication endpoint or a communication heavy distribution point, linked to other nodes. Each node in the network is considered to be equal, but some dots play a different role in the way they support the network. For example, not all nodes store complete copies of the block chain.
一个完整的节点下载一个区块链的完整副本，并根据该特定加密货币或实用代币所使用的共识协议检查产生的新事务。所有节点都使用相同的共识协议来保持相互兼容。网络中的节点负责确认和验证事务，并将它们放入块中。对于一个事务是否有效以及是否应该添加到带有其他事务的块中，不管其他节点如何行动，节点总是可以得出自己的结论。
A complete node downloads a complete copy of a block chain and checks the new matter according to the consensus agreement used for that particular encrypted currency or functional token. All nodes use the same consensus agreement to maintain compatibility. The nodes in the network are responsible for the identification and certification services and place them in blocks. For the validity of a matter and whether it should be added to a block with other matters, regardless of how the other node acts, the node can always draw its own conclusions.
我们以比特币的区块链系统为例。比特币一个新区块诞生的时间系统设定为十分钟。
We take the bitcoin block chain system as an example. Bitcoin's new block was set for 10 minutes.
一笔交易产生以后，为了让全网承认有效，必须先广播到区块链网络中其他参与的节点(链接的计算机);
When a transaction arises, in order for the entire network to be recognized as valid, it must be broadcast to other participating nodes in the block chain network (connected computers);
每个节点要正确无误地给这十分钟的交易都盖上时间戳，并且放进这个区块;
Each node is correctly provided with a time stamp on the transaction for 10 minutes and is placed in the block;
如果一个节点解开了随机数那道数学题，拥有了合法区块记账权，这个节点就会向全 网公布他这 10 分钟所有盖上时间戳的交易，并由全网中其他参与的节点来核对;
If a node solves the random number of mathematical questions and has legal block rights, this node announces to the whole network all transactions for which he has time stamped for 10 minutes and is checked by other participating nodes of the whole network;
比特币系统会给赢下合法区块记账权的节点以奖励，他广播以后，别的节点就要核对这个区块记账的准确性。别的节点其实同时也在解那道数学题，同时也在盖时间戳，只不过他们没有在那道数学题上算得更快。也就是说，这个区块他们赢不了奖励了，他们只好在下一个区块上想办法。
The bitcoin system rewards the node that wins the right to keep a legal block, and when he broadcasts, another node checks the accuracy of the block's account. The other node is also solving the math question and stamping it at the same time, except that they don't count faster on it. That is, they won't win the prize, and they have to work on the next block.
5.一般来说，每一笔交易，必须要经过 6 次的确认，也就是要通过 6 个的 10 分钟记账，才能在系统里被承认为是合法交易，一次的记账是不被承认的。
5. Generally speaking, each transaction must be confirmed six times, i.e. it must be accounted for 10 minutes of six minutes before it can be recognized as a legal transaction in the system and once it is not recognized.
通过以上介绍，相信大家对于区块链节点有所了解。区块链节点有着促进经济输出的优点，可以加快区块链科普教育，使得区块链回归到本质，区块链节点可以是联机的，也可以是脱机的，所以区块链节点还是比较安全。
From the above, we believe that there is some understanding of the points of the block chain. The points of the block chain have the advantage of promoting economic output, accelerating the education of the block chain and bringing it back to its essence. The points of the block chain can be online or offline, so that the points of the block chain are safe.
