在比特币中，区块链是什么？这种情况是比特币社区中最常见的问题之一。区块链是比特币的核心技术，是一个去中心化的公共帐簿，记录了比特币网络上发生的全部交易。那么，下面我们一起来看看在比特币中区块链是什么，以及比特币和区块链的关系是怎么样的。
In Bitcoin, what is the block chain? This is one of the most common problems in the Bitcoin community. The block chain is the central technology of Bitcoin, a decentralised public ledger that records all the transactions that took place on the Bitcoin network.
1、区块链的基本原理
1, Fundamentals of Block Chain
区块链是一个去中心化的公共帐簿，它由诸多区块组成，每个区块包括了多个交易明细。每个区块都有一个唯一的哈希值，及其前一个区块的哈希值。这类哈希链接构成了一个日益增长的链，也就是所谓的区块链。所有的比特币节点都能够下载区块链，便于验证交易实效性和完整性。
The block chain is a decentralised public ledger consisting of blocks, each of which contains several details of transactions. Each block has a single Hashi value, and the Hashi value of the previous block. The Hashi link forms a growing chain, the so-called block chain. All bitcoin nodes are capable of downloading the block chain to verify the validity and integrity of the transaction.
比特币区块链的运行体制是这样的：当有人要推送比特币时，网络中的矿工会搜集这些交易，把它们打包成一个区块，然后进行哈希计算。哈希计算的目的是为了把这个区块的所有交易明细转化成一个电子签名。这个电子签名在比特币网络中是唯一的，因此可用于验证整个区块的完整性和精确性。
The system of operation of the Bitcoin block chain is as follows: when someone wants to send Bitcoin, the mining unions in the network collect these transactions, wrap them into a block, and then compute Hashi. The purpose of Hashi calculation is to convert all the details of the block into an electronic signature. This electronic signature is the only one in the Bitcoin network and can therefore be used to verify the integrity and accuracy of the block as a whole.
2、区块链安全性
比特币区块链安全性是由共识算法来保证的。共识算法是指在比特币网络中全部节点之间达成的一种一同认知，他们觉得全部交易明细都真实存在，而且没有人可以篡改或双重花费。为达成这个共识，比特币网络使用了一种叫做工作量证明的算法。
The security of the Bitcoin block chain is guaranteed by consensus algorithms. Consensus algorithms refer to a confluence between all the nodes in the Bitcoin network, where they feel that all the details of the transaction are real and no one can alter or double the cost. To reach this consensus, the Bitcoins network uses an algorithm called workload proof.
工作量证明算法是指在比特币网络中，矿工要进行大量计算来检验并打包交易，因此矿工必须消耗大量的电力和计算资源。这类耗费能够确保比特币网络安全性，由于攻击者需要花费同样的资源才可以进攻网络。由于这种算法的存有，比特币在一定程度上具备防篡改的特点，因此成为了一种安全可靠的数字货币。
Workload certification algorithms mean that in the Bitcoin network, miners are required to consume large amounts of electricity and computing resources because of the volume of calculations that they perform in order to test and package transactions. Such costs ensure the safety of the Bitcoins network, which the attackers need to spend the same resources to attack the network. Because of the existence of such algorithms, bitcoins become a safe and reliable digital currency.
3、区块链的不可篡改性
3, the non-frozen nature of the block chain
比特币区块链的不可篡改性是指一旦交易明细被写入区块链，就不能被删除或修改。这类不可篡改性是由区块链的算法设计来决定的。每个区块都包括了前一个区块的哈希值，因此一旦前一个区块被篡改，后续的区块也会影响到，从而导致整个区块链的构造产生变化。
The non-frozen nature of the bitcoin block chain means that once the details of the transaction are written into the block chain, they cannot be deleted or modified. This type of non-frozenness is determined by the algorithm of the block chain. Each block includes the Hashi value of the previous block, so that, once the previous block has been tampered with, the subsequent block will also affect the structure of the entire block chain, leading to a change in the structure of the block chain.
比特币区块链的不可篡改性同时也得益于公开透明的特点。所有人都可以查询比特币上的交易明细，而且每个节点都能够验证这些交易实效性。这类公开化促使攻击者难以篡改区块链上的交易明细，因为所有的节点都会验证这些纪录的真实性。
All can check the details of the transactions on the bitcoin, and each node can verify the validity of the transactions. Such openness makes it difficult for the attackers to alter the details of the transactions on the block node, because all nodes verify the authenticity of the records.
1、比特币是区块链的第一种应用
1, Bitcoin is the first application of the block chain
区块链是一种分布式数据库，这是将数据分散存储在网络节点上，从而保障数据的安全性和稳定性。每个区块都包含一个或多个交易明细，每个交易明细均由电子签名维护，以保证安全。这个区块链的概念最早要在2008年由中本聪（Satoshi Nakamoto）提出的，而比特币也是在提出的基础上建立的。
The block chain is a distributed database that ensures the security and stability of data by decentralizing it to network nodes. Each block contains one or more details of the transaction, each of which is maintained by an electronic signature to ensure security. The concept of the block chain was first developed in 2008 by Satoshi Nakamoto, and Bitcoin was established on the basis of the proposal.
比特币是区块链技术的第一个应用，这将区块链技术用以数字货币的交易中。比特币交易被保存在区块链上，并由节点共同维护和验证。这类分布式结构促使比特币的交易安全，不会受到组织或个人的影响。它去中心化的特性促使比特币的交易能够在全球范围内开展，而且不管时间地点都可以直接。
Bitcoin is the first application of block chain technology that allows block chain technology to be used in transactions involving digital currencies. Bitcoin transactions are kept on the block chain and are jointly maintained and validated by nodes. This distribution structure makes Bitcoin transactions safe and free of organizational or personal influence. Its decentralized character enables Bitcoin transactions to take place on a global scale, regardless of time and place.
2、区块链是比特币的基础
区块链是比特币的基础，这是因为其记录了比特币交易的全部信息。比特币的形成、交易、转账等所有数据都被保存在区块链上。区块链促使比特币的交易变得更加透明与安全。所有人都可以查询区块链上的数据，这使得比特币的交易方式变得更加公开和透明。
The block chain is the foundation of Bitcoin, because it records all the information about bitcoin transactions. All the data on bitcoin formation, transactions, transfers, etc. are kept on the block chain. The block chain makes bitcoin transactions more transparent and secure. All people have access to data on block chains, which makes bitcoin transactions more open and transparent.
区块链还可以确保比特币的交易不受篡改。每个新的交易都被导入到区块链上，每个区块都包括了前一个区块的哈希值。当有人想要篡改任何一个区块，他一定要修改该区块及其以后的全部区块。这是基本不可能的，因为他必须攻击者掌握区块链网络上大部分节点计算水平。
Block chains also ensure that bitcoin transactions are not tampered with. Each new transaction is imported into the block chain, each of which includes the Hashi value of the previous block. When someone wants to tamper with any block, he must modify the block and all subsequent blocks. This is virtually impossible, because he must have control over most of the nodes of the block chain network.
3、区块链的应用不只是比特币
3, the use of block chains is not limited to bitcoin
尽管比特币是区块链的第一个应用，但区块链不仅限于数字货币。实际上，区块链技术已经被应用于很多其他领域。比如，区块链可以用于纪录物流详情、医疗记录、政府文档等等。区块链的去中心化构造使之适用于任何需要验证和记录数据的行业。在这些领域中，区块链的优点一样显现出来，它能够确保数据安全和确定性，同时也提升了数据处理效率。
Bitcoin is the first application of the block chain, but the block chain is not limited to digital currency. In fact, block chain technology has been applied in many other areas. For example, block chain can be used to record logistics details, medical records, government files, etc. Decentralize the block chain to any industry that needs to verify and record data.
4、区块链技术的未来
随着区块链技术的不断进步，它应用范畴可能越来越普遍。区块链技术在金融行业内的应用现在开始显出，但在其他领域的应用也越来越多。随着新技术和应用的出现，区块链将会变得更加完善和优化。
As block chain technology progresses, its application may become more widespread. The use of block chain technology in the financial sector is beginning to become apparent, but it is also increasing in other areas.
总的来说，比特币区块链是一种去中心化的公共帐簿，它由诸多区块组成，每个区块包括了多个交易明细。区块链的基本原理是由哈希链接将每个区块连接在一起，最终形成一个日益增长的链。而比特币和区块链技术之间的关系是相互依赖的。比特币是区块链技术的第一个应用，而区块链技术则支撑了比特币的交易和安全性。区块链技术的应用现在开始从数字货币拓展到其他领域，将来的发展前景十分广阔。
In general, the Bitcoin block chain is a decentralised public ledger consisting of blocks, each of which contains several details of transactions. The rationale for the block chain is that the Hash link connects each block, eventually forming a growing chain.
