据鑫链财经报道（xinchaincaijing.com），比特币与比特币现金:BTC和BCH有什么不同？
According to Xinchaincaijing.com, Bitcoin and Bitcoin cash: What's the difference between BTC and BCH?
比特币(BTC)和比特币现金(BCH )有着超越名字的相似之处。比特币是第一种被创造出来的加密货币，通常被视为数字黄金，或“黄金2.0”加密货币被视为价值存储和通胀对冲。而比特币现金是一种加密货币，旨在充当数字现金，其支持者试图确保它便宜且易于使用。BCH是通过所谓的硬叉子BTC，这意味着两种资产共享交易历史，共同的代码基础和更多。硬分叉是对比特币等加密货币区块链背后的开源软件的彻底升级。当与区块链的最新版本产生永久性分歧，并且运行网络的一些计算机不再符合共识时，就会发生这种情况。这就在区块链上产生了一个分叉，一边继续遵循旧规则，另一边遵循一套新规则。
bitcoin (BTC) and bitcoin cash (BCH) have a similarity beyond their names. Bitcoin is the first encrypted currency created, usually considered digital gold, or “gold 2.0” encrypted currency, is considered a value deposit and inflation hedge. Bitcoin cash is an encrypted currency designed to act as digital cash, and its supporters seek to ensure that it is cheap and easy to use. BCH is a so-called hard fork, which means sharing the history of two asset transactions, a common code base and more. The hard fork is a complete upgrade of the open source software behind the chain of encrypted currency blocks, such as a bitcoin. This happens when there is a permanent disagreement with the latest version of the block chain and some computers running the network no longer conform to consensus. This creates a split on the block chain, which continues to follow the old rules and a new set of rules on the other side .
比特币规模之争
自诞生以来，围绕比特币能否有效扩大规模并成为一种广泛使用的全球货币的问题一直在流传。加密货币使用区块链技术，这使得它可以去中心化，并且可以抵抗审查。尽管如此，这项新技术有一个重要的权衡:比特币区块链每秒可以处理的交易量——交易吞吐量。
since birth, there has been a circulation of questions about whether Bitcoins can be effectively scaled up and become a widely used global currency. Encrypted currency uses block chain technology, which allows it to be centralized and resistant to censorship.
例如，支付提供商Visa目前每天处理1.5亿笔交易，平均每秒处理1，700笔交易。该公司表示，它的能力甚至可以让它达到每秒24，000次交易。
for example, Visa, the paying provider, currently handles 150 million transactions per day, an average of 1,700 transactions per second. The company says it can even make it 24,000 transactions per second.
比特币区块链在目前的状态下，每秒钟可以处理大约7笔交易。这种差异是惊人的，而且随着网络用户数量的增长，每个事务本质上都是由数据组成的。
The Bitcoin block chain can handle about seven transactions every second in its current state. This difference is amazing and, as the number of network users increases, each transaction is essentially composed of data.
这些数据存储在区块链上，可以看作是一系列数据块。比特币网络上的每个区块被限制为1 MB的数据。随着网络需求的增长，大量未确认的交易开始形成。
The data are stored on the block chain and can be considered a series of data blocks. Each block on the Bitcoin network is limited to 1 MB data. As network demand increases, a large number of unconfirmed transactions begin to form. 在某些时候，积压的交易有100 000多项等待确认。网络决定哪些交易可以进行，哪些不可以进行的方式是基于每笔交易的费用。费用越高，交易处理越快。 The backlog of transactions is sometimes over 100,000 awaiting confirmation. The network determines which transactions can and cannot be done in a manner based on the cost of each transaction. The higher the cost, the faster the transaction is processed. 当网络堵塞，对有限空间的竞争加剧时，交易费用飙升至一笔交易可能花费用户多达58美元，将一些用户挡在网络之外。 At a time of network congestion and increased competition for limited space, transaction costs could soar to a transaction at a cost of up to $58, excluding some users from the network. 为了解决比特币的可扩展性问题，该社区分为两个主要解决方案:一个是增加块大小，以允许更多的交易适合每个块，另一个是通过第二层解决方案保持1 MB的块大小和规模。 To address the expansion of Bitcoin, the community is divided into two main solutions: one is to increase the size of the block to allow more transactions to suit each block, and the other is to maintain the size and size of the 1 MB through the second tier of the solution. 两种解决方案都有所取舍，随着时间的推移，他们的提议在社区中造成的分歧只会越来越大，因为双方都开始指责对方进行某种形式的操纵。这场辩论最终导致了艰难的分叉。 Both solutions have a trade-off, and over time their proposals will only create more and more divisions in the community, as both sides begin to accuse each other of some form of manipulation. This debate eventually leads to a difficult split. 比特币现金硬分叉 2017年5月23日，代表超过85%保障网络安全的计算能力的若干比特币企业主和矿工闭门举行会议，决定BTC的未来。出来的是所谓的SegWit2x升级。 May 23, 2017, a closed meeting of a number of Bitcoin entrepreneurs and miners representing more than 85% of their computing capacity to secure the network was held to determine the future of BTC. So-called SegWit2x upgrades. SegWit2x旨在通过实施隔离见证(SegWit)来帮助比特币扩展，这是一种在有限的块空间之外“隔离”一些数据并将块大小调整为2 MB的升级，将通过硬分叉来实现。该提议遭到了社区的反对，因为比特币的主要代码库没有得到代表，它被视为一种集中力量。 SegWit2x aims to help Bitcoin expand by implementing SegWit, an upgrade to “segregate” some data outside a limited space and resize the block to 2 MB, which will be achieved by hard fork. The proposal was opposed by the community, as Bitcoin's main code bank was not represented and it was considered a concentration force. 在比例缩放辩论中，那些支持小区块的人反对增加区块大小，因为这会增加区块链的大小。他们认为这将使托管一个完整的节点变得更加困难，可能会使加密货币集中化，使其更加脆弱。另一方面，那些支持更大块的人主张更快的解决方案，担心BTC不断上涨的交易费会损害加密货币的发展。 In the scale-up debate, those who support small blocks opposed increasing the size of blocks, as it would increase the size of the block chain. They argued that this would make it more difficult to hold a complete node and could centralize encryption and make it more vulnerable. On the other hand, those who support the larger block advocated faster solutions, fearing that the rising transaction costs of BTC would undermine the development of encrypted currency. 这场辩论最终导致了一场艰难的分叉，因为那些支持更大区块的人决定在2017年8月1日分叉比特币区块链。叉子创造了比特币现金，一种加密货币，其支持者将其视为一种中本聪最初设想的延续。 The debate eventually led to a difficult split, as those who supported the larger blocks decided to split the bitcoin block chain on August 1, 2017. The fork created bitcoin cash, an encrypted currency, and its supporters saw it as a continuation of the original vision of medium-breathing. 比特币现金与比特币有何不同 随着时间的推移，比特币和比特币现金之间的差异越来越大，因为每个网络上的开发者都有不同的目标。两种加密货币之间的差异变得如此之大，它们现在被视为社区中完全不同的资产。 The difference between bitcoin and bitcoin cash over time is growing because each web developer has a different goal. The difference between the two encrypted currencies becomes so great that they are now regarded as completely different assets in the community. 难度调整 strong> difficulty adjustment 比特币和比特币现金的一个主要区别是加入了BCH的难度调整算法。由于这两个网络使用相同的SHA-256哈希方案，当比特币矿工在比特币现金网络上采矿变得更有利可图时，他们可以转移到比特币现金网络。 A major difference between bitcoin and bitcoin cash is the inclusion of a difficulty adjustment algorithm for BCH. Because the two networks use the same SHA-256 Hash scheme, bitcoin miners can move to bitcoin cash when mining on bitcoin cash networks becomes more profitable. 这意味着，考虑到市场的波动，网络背后的计算能力可能会有很大差异。难度调整算法确保每10分钟生成一个稳定的块，如果它们落后于计划，则难度减半，如果它们超前，则难度加倍。 means that the computing power behind the network may vary considerably, given the volatility of the market. The difficulty adjustment algorithm ensures that a stable block is generated every 10 minutes. If they lag behind the plan, the difficulty is halved, and if they are ahead of schedule, double. 块大小差异 strong 主要区别与每个网络的块大小有关。虽然比特币保持1 MB的块大小，但随着比特币现金的出现，块大小已经增长到32 MB。这意味着现在在BCH上的交易成本不到一便士，每秒钟可以处理多达200笔交易。 The main difference relates to the size of a block in each network. Although Bitcoin maintains a block size of 1 MB, the size of the block has grown to 32 MB with the emergence of bitcoin cash. This means that now the transaction costs less than a penny on BCH, and up to 200 transactions can be processed every second. 由于比特币现金没有处理足够多的交易来填充其额外的块空间，区块链的规模没有像预测的那样呈指数增长。比特币SV(巴-斯-沃三氏综合征)——一种通过比特币现金分叉创造的加密货币——正在寻求将其块大小提高到1 TB，其区块链的大小现在比比特币的大得多。 The size of the block chain has not increased exponentially as projected because bitcoin cash does not handle enough transactions to fill its extra space. BitcoinSV (B-S-V-O-III syndrome) - an encrypted currency created through bitcoin cash splits - is seeking to raise its block size to 1 TB, and its block chain is now much larger than Bitcoin. 智能合同和分散融资 比特币不支持智能合约，尽管工作正在进行中帮助建立分散的金融体系正如Square首席执行官杰克·多西透露的那样。与此同时，比特币现金已经开始使用Cashscript等智能合约语言来实现更复杂的功能。 bitcoin does not support smart contracts, although work is under way to help build a fragmented financial system, as Chief Executive Jack Dossy revealed. Meanwhile, bitcoin cash has started to use smart contract language like Cashscript to achieve more complex functions. Cashscript旨在将DeFi引入比特币现金，以帮助其与比特币和以太坊(埃塞俄比亚).一些已经开发的工具包括CashSuffle和CashFusion，旨在提高网络隐私。 Cashscript aims to introduce DeFi into Bitcoin cash to help it with Bitcoin and Etheria (Ethiopia).... Some of the tools that have been developed include CashSuffle and CashFusion, aimed at improving Internet privacy. 代币发行 为了在比特币区块链之上发行代币，项目必须使用Omni layer，这是一个“用于创建和交易定制数字资产和货币”的平台Omni交易是具有“下一代功能”的比特币交易，但该层的采用主要集中在stablecoins上。 In order to issue a token on the Bitcoin block chain, the project has to use Omnilayer, a platform for creating and trading customized digital assets and currencies, Omni transactions are Bitcoins transactions with “next-generation functions”. 另一方面，比特币现金创造了简单的账本协议(SLP)。该协议允许开发者在BCH上发行代币，类似于在以太坊区块链上发行代币的方式。 , on the other hand, Bitcoin cash creates a simple account book agreement (SLP). The agreement allows developers to issue tokens on the BCH, similar to those issued on the Taiwan block chain. 一些资产已经在Omni层和作为SLP代币发行。存在于不同的区块链上使得用户更容易选择他们喜欢的网络。然而，这两种解决方案的采用都有些乏善可陈。 a number of assets have been issued on the Omni level and as SLP tokens. The existence of different block chains makes it easier for users to choose the network they like. However, both solutions are somewhat unsatisfied. SLP协议还支持不可伪造的令牌(NFT ),这些令牌是可以相互区分的。然而，与它们在以太坊或其他区块链上的使用相比，它们在BCH上的使用受到了限制。 SLP also supports non-false tokens (NFTs), which can be distinguished from each other. However, their use on BCH is restricted compared to their use in the chain of Etheria or other blocks. 按费用替换 按费用替换(RBF)是比特币网络上的一项功能，允许某人获得一项未经处理就被“卡住”的交易，用附加更高交易费用的不同版本替换未经确认的交易。 Replacement at Cost (RBF) is a function of the Bitcoin network that allows a person to obtain an unprocessed transaction that is “cuffed” and replaces an unconfirmed transaction with a different version with higher transaction costs. 当交易需要尽快处理时，可以使用RBF，但其批评者声称，这可能使恶意行为者更容易两次花费相同的资金。他们认为，攻击者可以用很少的费用发送一笔交易，作为对使用RBF的商品或服务的支付。如果收件人没有在网络上等待足够的确认，他们就可以向他们控制的钱包发送相同的交易，但费用更高。 RBF can be used when a transaction needs to be processed as soon as possible, but its critics claim that this may make it easier for malicious actors to spend the same money twice. They believe that the attackers can send a transaction at a very small cost as a payment for goods or services using the RBF. If recipients do not wait for sufficient confirmation on the network, they can send the same transaction to their wallets under their control, but at a higher cost. 网络将首先确认该第二交易，并丢弃向商家支付他们的商品或服务的交易。大多数版本的RBF要求事务包含所有相同的输出以防止这种情况。而且，如果接收方等待几个网络确认，RBF就变得不可能了，因为交易已经确认了。 net will first confirm the second transaction and discard the transaction that pays the merchants for their goods or services. Most versions of the RBF require that the transaction contain all the same output to prevent this. And if the recipient waits for several networks to confirm it, the RBF becomes impossible because the transaction has been confirmed. 然而，比特币现金已经放弃了这一功能，使得未经确认的交易在其网络上不可逆转。鉴于其更高的交易吞吐量，与RBF的双重支出将变得更加困难，因为交易得到确认的速度更快。 , however, Bitcoin cash has abandoned this function, making unconfirmed transactions irreversible on its network. Given its higher volume of transaction throughput, double spending with the RBF will become more difficult, as transactions are confirmed faster. 不同的愿景，相同的货币政策 strong> different visions, same monetary policy 比特币现金在硬分叉的时候是以8 MB的块大小创建的，此后翻了两番。该网络公开接受新的硬分叉，并采取措施尽可能多地进行创新，以增加其可用性并被用作现金。 bitcoin's cash was created in the size of 8 MB at the hard fork, and has quadrupled since then. The network openly accepts new hard fork and takes measures to innovate as much as possible to increase its availability and use it as cash. 另一方面，比特币在推出升级时更加谨慎，更多地被视为通胀对冲和价值储存手段。其扩展计划见证了SegWit的实施和闪电网络的创建。 , on the other hand, Bitcoin was more cautious when introducing the upgrade and was more likely to be seen as an inflation hedge and a value storage tool. Its expansion plan witnessed the implementation of SegWit and the creation of a lightning network. 闪电网络本质上是在加密货币的区块链之上创建了一个额外的层，在这里交易快速，费用极低。这一层由用户生成的支付渠道组成。据估计，它每秒能够处理1500万次交易，但它的采用相对缓慢。 The lightning network essentially creates an additional layer above the block chain of encrypted currency, where transactions are fast and very cheap. This layer is made up of user-generated payment channels. It is estimated that it can handle 15 million transactions per second, but its adoption is relatively slow. 比特币还试图通过Taproot等升级来保护用户的假名，这使得包括timelock版本或多签名组件在内的复杂交易可以被视为简单交易。使用Taproot，创建Lightning网络通道的事务或简单的事务是无法区分的。 bitcoin also tries to protect the user's pseudonyms by upgrading such as Taproot, so that complex transactions, including timelock versions or multi-signature components, can be considered simple transactions. 比特币的支持者更看重去中心化和抵制审查，而不是更高的交易吞吐量。比特币作为价值储存手段的角色取决于它抵御任何可以想象的实体攻击的能力。 bitcoin's supporters value decentralisation and rejection of censorship more than higher transactional tossage. Bitcoin's role as a value storage tool depends on its ability to resist any conceivable physical attack. 比特币现金作为点对点电子现金的愿景取决于其低交易费用和更快的速度。一些建立在BCH之上的项目，包括社交媒体平台，每个帖子都在区块链上发布，在比特币上是不可行的。 bitcoin's vision as point-to-point e-cash depends on its low transaction costs and faster speed. Some projects based on the BCH, including social media platforms, each post is posted on the block chain and is not feasible in bitcoin. 比特币现金的隐私通过一种不同的方法得到保护:硬币混合。硬币混合看到许多BCH用户的交易被捆绑在一起，以掩盖用户硬币的来源。这是一种有争议的做法，被认为有助于网络罪犯隐藏他们的踪迹。 the privacy of bitcoin cash is protected by a different method: a coin mix. A coin combination sees many BCH users tied together to conceal the origin of the user's coin. This is a controversial practice that is considered to help cybercriminals hide their whereabouts. 这两个网络的货币政策保持不变。每个区块链上只会创造2100万枚硬币，每21万个街区或大约每四年，新硬币的发行就会减半。最后的BTC和BCH预计将在2140年开采。 the monetary policy of the two networks remains unchanged. Only 21 million coins are created on each block chain, halving the issuance of new coins every 210,000 blocks or about every four years. The final BTC and BCH are expected to be mined in 2140. 这两种加密货币都是为了防范货币没收、审查和高于预期的通胀导致的贬值。这两个区块链都是透明的，公众可以访问，不能由一个实体改变。 总的来说，以上内容讲解了比特币与比特币现金的区别，相信大家看了后会清晰的了解它们的不同之处。比特币是第一种被创造出来的加密货币，而比特币现金是一种加密货币，旨在充当数字现金，其支持者试图确保它便宜且易于使用。 In general, the above explains the difference between bitcoin and bitcoin cash, and I'm sure you'll see the difference clearly. Bitcoin is the first encrypted currency created, while bitcoin cash is an encrypted currency designed to serve as digital cash, and its supporters try to ensure that it is cheap and easy to use.
