比特币挖矿是什么意思？比特币挖矿是获取比特币最原始的方法，一开始大家想要获得比特币只能通过挖矿的方式，那么比特币挖矿到底是什么意思呢？通常人们把比特币说成数字黄金，价格高，数量有限，接下来小编就带来详细的比特币挖矿解释介绍。
What do you mean by bitcoin mining? Bitcoin mining is the most primitive way to get bitcoin, and first people want bitcoin to be mined only by digging, so what does bitcoin mining mean? People usually describe bitcoin as digital gold, expensive and limited, and then the little editor comes up with a detailed explanation of bitcoin mining.
什么是比特币挖矿?
其实，比特币挖矿是一个形象的说法;人们也经常把比特币说成是“数字黄金”，因为比特币总量和黄金一样有限，而且价格不菲。 Indeed, bitcoin mining is an image; bitcoin is often described as “ digital gold & rdquo; because bitcoin is as limited as gold and expensive. 黄金是从金矿里挖出来的，比特币是由旷工从数字里面“挖”出来的。这里的所指的“挖矿”和“矿工”，与我们日常生活里的所指有所不同。日常生活里，“挖矿”是指矿工开采如黄金、煤炭等天然矿产的过程，“矿工”自然是指挖矿的工人。而在比特币世界里，“矿”是比特币，所以“挖矿”是指挖比特币，“矿工”是指运用挖矿设备(比特币矿机)参与挖比特币的人。 Gold is excavated from our daily lives. In everyday life, “ excavating & rdquo; bitcoin is the process of mining natural minerals such as gold, coal; miner & & rdquo; nature is the worker who digs mines. And in bitcoin, & & rdquao; miner & & rdquo; diggers & & rdquo; miners & & & rdquo; people who dig bitco. 比特币挖矿原理：
比特币系统由用户(用户通过密钥控制钱包)、交易(交易都会被广播到整个比特币网络)和矿工(通过竞争计算生成在每个节点达成共识的区块链，区块链是一个分布式的公共权威账簿，包含了比特币网络发生的所有的交易)组成。 The Bitcoin system consists of users (users control wallets by key), transactions (transactions are broadcast throughout the Bitcoin network) and miners (competition calculations generate a chain of blocks agreed upon at each node, which is a distributed public authority account containing all transactions occurring in the Bitcoin network). 比特币矿工通过解决具有一定工作量的工作量证明机制问题，来管理比特币网络-确认交易并且防止双重支付。由于散列运算是不可逆的，查找到匹配要求的随机调整数非常困难，需要一个可以预计总次数的不断试错过程。这时，工作量证明机制就发挥作用了。当一个节点找到了匹配要求的解，那么它就可以向全网广播自己的结果。其他节点就可以接收这个新解出来的数据块，并检验其是否匹配规则。如果其他节点通过计算散列值发现确实满足要求(比特币要求的运算目标)，那么该数据块有效，其他的节点就会接受该数据块。 Bitcoin miners manage the Bitcoin network - confirming transactions and preventing double payments by resolving the problem of workload proof mechanisms with a certain workload. Because hash transport is irreversible, it is very difficult to find random adjustments to match requirements, requiring a continuous error process that can predict a total number of times. At that point, the workload proof mechanism works. When a node finds a solution to match requirements, it can broadcast its own results to the entire network. Other nodes can receive this newly released data block and test its matching rules. If other nodes are found to satisfy the requirement (the target of calculating the bitcoins) by calculating the hash value, then the data block is valid and the other nodes will accept the data block. 中本聪把通过消耗CPU的电力和时间来产生比特币，比喻成金矿消耗资源将黄金注入经济。比特币的挖矿与节点软件主要是透过点对点网络、数字签名、交互式证明系统来进行发起零知识证明与验证交易。每一个网络节点向网络进行广播交易，这些广播出来的交易在经过矿工(在网络上的计算机)验证后，矿工可使用自己的工作证明结果来表达确认，确认后的交易会被打包到数据块中，数据块会串起来形成连续的数据块链。每一个比特币的节点都会收集所有尚未确认的交易，并将其归集到一个数据块中，矿工节点会附加一个随机调整数，并计算前一个数据块的SHA256散列运算值。挖矿节点不断重复进行尝试，直到它找到的随机调整数使得产生的散列值低于某个特定的目标 Each network node carries out a broadcast transaction to the network, which, after verification by the miners (computers on the network), the miners can use their work certificate to confirm that the confirmed transaction will be packaged into the data block, where the data block will be chained up into a continuous data chain. Each bitcoin node collects all unrecognizable transactions and brings them together into a data block, with a random adjustment attached to the mine node and calculates the SHA256 bulk value of the previous data block. 比特币挖矿常用的矿机种类： the type of miner commonly used in bitcoin mining: ASIC矿机 ASIC矿机是指使用ASIC芯片作为核心运算零件的矿机。ASIC芯片是一种专门为某种特定用途设计的芯片，必须说明的是它并不只用于挖矿，还有更广泛的应用领域。这种芯片的特点是简单而高效，例如比特币采用SHA256算法，那么比特币ASIC矿机芯片就被设计为仅能计算SHA256.所以就挖矿而言，ASIC矿机芯片的性能超过当前顶级的电脑CPU。因为ASIC矿机在算力上有绝对的优势，所以电脑、显卡矿机开始逐渐被淘汰。 The ASIC miner is a mine that uses the ASIC chip as a core computing component. The ASICI chip is a chip that is specifically designed for a specific purpose, and it must be stated that it is not only for mining, but also for a wider range of applications. This chip is characterized by simplicity and efficiency, such as the fact that Bitcoin uses the SHA256 algorithm, so that the Bitcoin ASI chip is designed to calculate only SHA256. Thus, in the case of mining, the ASI chip has a greater performance than the current top computer CPU. GPU矿机 GPU Miner GPU矿机，简单的解释就是通过显卡(GPU)挖矿的数字货币挖矿机。在比特币之后，陆续出现了一些其他数字资产，比如以太坊、达世币、莱特币等等，其中一些币所用的算法与比特币并不相同，为了达到更高的挖矿效率，矿工们做了不同的测试，最后发现SHA256算法的数字货币使用ASIC挖矿效率最高。而Scrypt 等其他算法的数字货币用GPU显卡挖矿效率最高，于是催生出了专门的GPU矿机。 The GPU miner, a simple explanation, is a digital money miner that digs through a card (GPU). After Bitcoin, there are a number of other digital assets that emerge, such as the same algorithms as Bitcoin, Dalcoin, Leitco, etc., some of which are used differently than bitcoins, and which are tested differently to achieve higher mining efficiency, the miners finally find that the digital currency of the SHA256 algorithm is the most efficient in mining with ASIC. IPFS矿机 IPFS类似于http，是一种文件传输协议。IPFS要想运行，需要网络中有许许多多的计算机(存储设备)作为节点，广义的说所有参与的计算机，都可以称作IPFS矿机。而IPFS网络为了吸引更多的用户加入成为节点，为网络做贡献，设计了一种名叫filecoin的加密货币，根据贡献存储空间与带宽的多少，派发给参与者(节点)作为奖励。狭义的说，专门以获取filecoin奖励为目的而设计的计算机，称为IPFS矿机。由于IPFS网络需要的是存储空间以及网络带宽，所以为了获得最高的收益比，IPFS矿机通常会强化存储空间、降低整机功耗等方面。比如装备10块以上大容量硬盘，配备千兆或更高速度的网卡，使用超低功耗的架构处理器等等。 IPFS is similar to http, a file transfer protocol. In order for IPFS to operate, it requires a large number of computers (storage equipment) in the network as nodes, and in a broad sense all participating computers can be called IPFS machines. In order to attract more users to join as nodes, the IPFS network has designed an encrypted currency called filecoin to provide incentives for participants (nodes) depending on the size of their contribution storage space and bandwidth. In the narrow sense, computers designed to obtain the filecoin reward, called IPFS machines. Because the IPFS network requires storage space as well as bandwidth, the IPFS mine usually enhances storage space, reduces whole machine power, etc. FPGA矿机 FPGA Miner FPGA矿机，既使用FPGA芯片作为算力核心的矿机。FPGA矿机是早期矿机之一，首次出现在2011年末，在当时一度被看好，但活跃期并不长，后逐渐被ASIC矿机与GPU矿机取代。FPGA(Field-Programmable Gate Array)，中文名叫现场可编程门阵列。比较通俗的理解是，FPGA就是把一大堆逻辑器件(比如与门、非门、或门、选择器)封装在一个盒子里，盒子里的逻辑元件如何连接，全部由使用者(编写程序)来决定。 The FPGA mine machine, which uses the FPGA chip as the core of the algorithm. The FPGA mine machine was one of the early machines, first seen in late 2011, and was once seen, but not for long, and was gradually replaced by the ASIC mine machine with the GPU miner. The FPGA (Field-Programme Gate Array), called the in situ programmable door array, is more commonly understood to be a lot of logical devices (such as doors, non-doors, doors, selections) that are contained in a box, all linked to the user (preparation process). 如果FPGA里面写的是挖矿程序，那么造出来的就是FPGA矿机，而且由于FPGA灵活度高，所以不只是可以支持比特币的SHA256算法，也可以支持GPU矿机擅长的Scrypt算法。FPGA矿机活跃的时期，相比同时代的CPU、GPU矿机，FPGA虽然算力性能不占优，但功耗要低很多，综合功耗比很高。 If FPGA is written as a mining program, then FPGA is created, and because of the flexibility of the FPGA, it is possible to support not only the SA256 algorithm in Bitcoin, but also the Scrypt algorithm that the GPU miner is good at. The FPGA miner is active, and FPGA is less effective than the co-generation CPU and GPU miner, but much less effective than the combined one.
