常见问题与解答
简单来说，数字货币就是加密报酬，区块链的安全需要大量的加密操作，而每一个为区块链进行加密的个体（硬件）都将获得区块链所给予的报酬，也就是我们俗称的数字货币。
验证交易的合法性并将区块链接在一起以制作区块链需要一种称为“加密哈希”的东西。数字货币社区内的人们帮助验证交易并将其添加到区块链中，称为挖矿，他们的努力获得数字货币。矿工使用功能强大的计算机来处理这个有价值的加密哈希。这就是所谓的挖矿。我们通过充当区块链基础设施来支持数字货币生态系统，这有助于验证交易并允许通过挖矿过程创建更多硬币。我们提供的基础设施允许人们购买和消费数字货币。
数字货币不受政府支持，也不以实物形式存在。你不能把虚拟货币拿在手上，就像你不能把它存入政府经营的银行一样。从法律的角度来看，数字货币是否真的是货币仍有待商榷
然而，一个事实仍然存在：数字货币具有现实世界的价值（尽管它会波动）并且可以用来交换商品和服务,也有大量的交易需求。即使是 Expedia、Red Bull、DISH Network 和 Shopify 等主要零售商也接受数字货币作为付款方式。
Simply put, digital currency is an encrypted reward. The security of the blockchain requires a large number of encryption operations, and every individual (hardware) that encrypts the blockchain will get the rewards given by the blockchain, which is what we commonly call Digital currency/crypto currency. Verifying the legitimacy of transactions and linking blocks together to make a blockchain requires something called a "cryptographic hash". People in the digital currency community help verify transactions and add them to the blockchain, called mining, their efforts to obtain digital currency. Miners use powerful computers to process this valuable cryptographic hash. This is called mining. We support the digital currency ecosystem by acting as a blockchain infrastructure, which helps verify transactions and allows more coins to be created through the mining process. The infrastructure we provide allows people to buy and consume digital currencies. Digital currency is not supported by the government, nor does it exist in physical form. You can't hold virtual currency in your hands, just like you can't deposit it in a government-run bank. From a legal point of view, whether digital currency is currency remains to be discussed
However, a fact still exists: the digital currency has real-world value (although it can fluctuate) and can be used to exchange goods and services, and there is also a large amount of transaction demand. Even major retailers such as Expedia, Red Bull, DISH Network, and Shopify accept digital currencies as payment methods.
Blockchain technology is a combination of algorithms that perform calculations and a distributed database that stores these calculations in a so-called blockchain. The database is constantly updated with its digital records (for example, Bitcoin transactions) and is updated on multiple computers at the same time. The database is completely decentralized, which means that there is no single entity to control it. Anyone can view the complete history of the database at any time.
Each group of records in the database is called a "block", and anything recorded in the database will always remain there. Due to the immutability of the database, once a record is entered, it is impossible to manipulate or change the record.
We know that a person named Satoshi Nakamoto invented Bitcoin, but to this day, the mystery of who Satoshi Nakamoto is remains unsolved. Is Satoshi Nakamoto a man? A woman? A group? A government? Although people now think it is a pseudonym, what is more, mysterious is the extreme wealth he, she, or they accumulated. It is estimated that Satoshi Nakamoto holds approximately 1,000,000 Bitcoins. At the time of writing, the value of a bitcoin is approximately US$40,000, which means that the person who invented bitcoin may be sitting on a fortune worth approximately US$40 billion.
The "distributed" part of a distributed ledger refers to the point-to-point aspect of its design. Distributed ledgers are stored on multiple "nodes" (usually computers) within the network, which means that records are kept in multiple geographic locations. This is in contrast to previous digital record-keeping methods, which store the ledger in a centralized location, such as a server, and managed by selected trusted individuals. Even if multiple systems can access a record, there is only one master ledger. When using DLT, there is no central server that provides the latest information and ledger version. On the contrary, the distributed ledger is designed with a consensus algorithm that allows nodes on the network to automatically "vote" on information and replicate it to all connected systems. This means that each node holds an up-to-date and verifiable copy of the record, which cannot be fraudulently changed because there is no "master" file to change, and most nodes must agree on the record. Distributed ledger technology is a revolutionary step in information collection and communication because it significantly affects the cost of trust and the reliability of the information. This world-changing technology supports the blockchain and some of the earliest and most widely used digital currencies, such as Bitcoin.
分布式账本的“分布式”部分是指其设计的点对点方面。分布式账本存储在网络内的多个“节点”（通常是计算机）上，这意味着记录保存在多个地理位置。这与以前的数字记录保存方法形成对比，这些方法将分类帐存储在一个集中位置，例如服务器，并由选定的受信任个人管理。即使多个系统可以访问一条记录，也只存在一个主分类账。
使用 DLT 时，没有提供最新信息和分类账版本的中央服务器。相反，分布式账本设计有共识算法，允许网络上的节点自动对信息进行“投票”，并将其复制到所有连接的系统中。这意味着每个节点都持有一份最新且可验证的记录副本，该副本不能被欺诈性地更改，因为没有要更改的“主”文件，并且大多数节点必须就记录达成一致。
分布式账本技术是信息收集和通信的革命性步骤，因为它显着影响了信任成本和信息的可靠性。这种改变世界的技术支撑着区块链和一些最早和最广泛使用的数字货币，例如比特币。
区块链是人类几十年来见过的最具破坏性的技术之一。它被描述为具有改变我们所知的世界的能力，其规模与电力或互联网相同。那么，为什么很少有公众听说过它呢？为什么区块链值得获得如此崇高的赞誉？
借助区块链技术，数据记录存储在一系列地理位置的多个节点上。这大大降低了因火灾、盗窃、自然灾害、黑客攻击和文件系统损坏而导致数据丢失的风险——所有这些风险都是由传统数据系统造成的。
如前所述，区块链的去中心化技术意味着网络上的每个人都持有一份普遍同意的交易记录的副本。任何后续的更改都必须被网络的大多数人接受，这使得串通几乎不可能。
由于线性区块链网络仅在追加的基础上运行，因此存在可追溯的数据链。这对供应链等运营尤其有用，因为区块链成为产品在其旅程中的每一站的可审计跟踪。
Blockchain is one of the most disruptive technologies that mankind has seen in decades. It is described as having the ability to change the world as we know it, on the same scale as electricity or the Internet. So why have few people heard of it? Why is blockchain worthy of such high praise? With the help of blockchain technology, data records are stored on multiple nodes in a series of geographic locations. This greatly reduces the risk of data loss due to fire, theft, natural disasters, hacker attacks, and file system damage-all of these risks are caused by traditional data systems. As mentioned earlier, the decentralized technology of blockchain means that everyone on the network holds a copy of a generally agreed transaction record. Any subsequent changes must be accepted by the majority of the network, which makes collusion almost impossible.
Since the linear blockchain network only operates on an additional basis, there is a traceable data chain. This is especially useful for operations such as supply chains, as the blockchain becomes an auditable trail of each step of the product's journey.
实际上，没有任何人或群体拥有对区块链完整控制权，这也成为了区块链最可信和安全的保障。虽然政府对其公民如何使用比特币以及如何报告其税收收益有发言权，但世界上没有政府可以控制整个比特币。这是因为比特币本身是去中心化和开源的。
任何落入单个实体手中或财产的东西都被称为中心化的。这可以是控制货币体系的单一政府、控制政策的个人或在市场上设定价格的唯一公司。比特币等虚拟货币以完全相反的方式运作。它是去中心化的，这意味着货币同时掌握在许多不同的人和实体的手中。任何比特币社区成员或运行比特币软件的人本质上都拥有比特币网络的所有权。
当有人下载比特币区块链时，该区块链包含自其成立以来发生的所有比特币交易记录，它们有助于防止未来的网络集中化。只要有任何人有任何一台设备参与比特币交易，它就会以去中心化的形式掌握在大众手中。比特币的去中心化不仅仅由那些充当完整节点的人（一个记录保存的比特币数据库维护者）来维护。它由整个比特币社区保存。
No one or group has complete control over the blockchain, which has become the most credible and safe guarantee of the blockchain. Although the government has a say in how its citizens use Bitcoin and how to report its tax revenue, no government in the world can control the entire blockchain. This is because blockchain itself is decentralized and open source. Anything that falls into the hands or property of a single entity is called centralized. This can be a single government that controls the monetary system, an individual that controls policy, or the only company that sets prices in the market. Virtual currencies such as Bitcoin operate oppositely. It is decentralized, which means that money is in the hands of many different people and entities at the same time. Any member of the Bitcoin community or anyone running Bitcoin software essentially owns the ownership of the Bitcoin network. When someone downloads the Bitcoin blockchain, the blockchain contains records of all Bitcoin transactions that have occurred since its inception, and they help prevent future network centralization. As long as anyone has any device to participate in bitcoin transactions, it will be in the hands of the public in a decentralized form. Bitcoin's decentralization is not only maintained by those who act as full nodes (a record-keeping Bitcoin database maintainer). It is kept by the entire Bitcoin community.
As explained by Nasdaq, the general concept of currency has changed from one system to another over the years. From gold and silver to paper money, to digital credit card transactions and digital currency, the concept of currency is fluid and evolving. Nasdaq explained that digital currency is not a "patch" of our current concept of currency value, but "another layer of abstraction added on top of an aging and overly complex system."
Since "tangible" monetary assets have been eliminated, Bitcoin and other digital currencies are likely to be an evolutionary step in our view (and response) to supply and demand. Bitcoin derives value from the needs of end-users and the frequency of transactions. Although Bitcoin may not be tangible, its scarcity is guaranteed due to the encoding method of the underlying algorithm, and there are no more than 21 million Bitcoins on the network. This scarcity helps Bitcoin to withstand threats such as inflation, and fiat currency always has to fight against it.
在接受 CNBC 采访时，加拿大央行行长斯蒂芬·波洛兹 (Stephen Poloz) 将投资数字货币比作投机性赌博，称数字货币不是资产，而是技术上没有内在价值的证券。他表示，如果只是为了保护消费者，法规即将出台。在同一次采访中，他表示，数字货币的底层技术——区块链——本身就是天才，应用非常广泛。波洛兹还解释说，尽管他提出了监管建议，但其目的并不是扼杀创新。
加拿大是第一个实施国家数字货币法来规范金融技术交易的国家。任何在加拿大从事虚拟货币交易的企业都必须在加拿大联邦金融情报部门 FINTRAC 进行注册，除非他们遵守注册和反洗钱合规协议，否则银行将拒绝提供服务。
加拿大仍然对区块链和数字货币领域的创新持非常开放的态度，尽管他们着眼于安全。事实上，加拿大已经在多伦多证券交易所批准了其第一个区块链交易所交易基金（ETF），股票代码为HBLK
加拿大仍然被广泛认为是最清楚他们对待加密货币的国家之一。这个加拿大网站提供了与数字货币相关的风险和义务的透明分类。它包括有关法定货币状态、纳税义务、数字货币 ATM 以及与数字货币相关的风险（例如保护较少和缺乏保险）的信息。但是，它也为选择使用数字货币的公民列出了基本的预防措施，包括钱包保护、兑换费用和等待交易确认。
尽管加拿大一开始确实是混合了各种想法和意见，但几乎所有已经开始讨论监管的国家都可以这么说。总的来说，加拿大似乎正在努力寻找一个合理、合理的中间立场，让创新思想蓬勃发展，同时保护其公民。截至目前，它们可能是北美对加密货币最友好的国家。
In an interview with CNBC, Bank of Canada Governor Stephen Poloz likened investment in digital currency to speculative gambling, saying that digital currency is not an asset, but the security that has no inherent value in technology. He said that if it is only to protect consumers, regulations will be introduced soon. In the same interview, he said that the underlying technology of digital currency-the blockchain-is itself a genius and is widely used. Poloz also explained that despite his regulatory recommendations, the purpose is not to stifle innovation.
Canada is the first country to implement a national digital currency law to regulate financial technology transactions. Any business that engages in virtual currency transactions in Canada must register with the Canadian Federal Financial Intelligence Agency FINTRAC. Banks will refuse to provide services unless they comply with the registration and anti-money laundering compliance agreements. Canada is still very open to innovation in the field of blockchain and digital currency, despite their focus on security. Canada has approved its first blockchain exchange-traded fund (ETF) on the Toronto Stock Exchange under the ticker symbol HBLK. Canada is still widely regarded as one of the countries that know their treatment of cryptocurrencies best. This Canadian website provides a transparent classification of the risks and obligations associated with digital currencies. It includes information about the status of legal tender, tax liability, digital currency ATMs, and digital currency-related risks (such as less protection and lack of insurance). However, it also lists basic precautions for citizens who choose to use digital currencies, including wallet protection, exchange fees, and waiting for transaction confirmation. Although Canada did mix various ideas and opinions at the beginning, almost all countries that have begun to discuss regulation can say the same. In general, Canada seems to be trying to find a reasonable middle ground to allow innovative ideas to flourish while protecting its citizens. As of now, they may be the most crypto-friendly country in North America.
Blockchain is a digital ledger that tracks information in a decentralized, time-stamped manner. Once recorded, it cannot be unilaterally maliciously changed. The types of information that each "block" may contain range from vital signs records in the healthcare industry to our digital currency transactions
Each information block is linked together in chronological order to create a data blockchain or blockchain. The particular innovation and importance of blockchain are that it is decentralized or decentralized in a peer-to-peer (P2P) network. There is no single server that houses the digital currency blockchain to track how everyone spends their money. On the contrary, many people have a record of digital currency blockchain. Anyone can download the current data for free and share it with other users. This makes anything on the blockchain very difficult, if not impossible, to crack. Everyone who has a copy of blockchain information is also sharing it with others on the blockchain, and everyone is updating their records to include the latest information. If someone wants to modify the blockchain and say they have 1 million bitcoins, everyone else on the network will say, "No, this doesn't look right" and will reject the data as invalid. The decentralization and immutability of the blockchain network make it the perfect foundation for digital currency. The task of the miner is to verify the transaction, and the problem to be solved is the cryptographic hash function. According to Ameer Rosic, the hash function is "essentially one-way encryption without a key", Who explained that cheating on these types of puzzles is impossible because there is no better way to solve them than guessing.
To guess the target cryptographic hash (which must be lower than a certain number), Bitcoin miners first generate "random numbers" or numbers that are used only once. To compare these numbers, the target hash is a 64-bit hexadecimal number, that is, 256 bits, while the random number in Bitcoin mining is only 32 bits. As mentioned earlier, the fewer digital currencies that can be mined, the more difficult it is to mine. Now, a random number has a viable chance of hashing, for example, one below the specified number, less than one part in 2 trillion-in other words, it is much harder than winning the lottery. However, when the miners succeed, they have implemented Proof of Work (PoW), which is a piece of data that "proves" that what they provide is difficult, time-consuming, and expensive. This allows others on the network to verify that their efforts are effective. Bitcoin uses a type of proof of work called "hash cash" to reward miners.
区块链是一种数字分类账，以分散的、按时间顺序加时间戳的方式跟踪信息，一旦被记录，就不可能单方面恶意更改。每个“区块”可能包含的信息类型从医疗保健行业的生命体征记录到我们的数字货币交易
每个信息块按时间顺序链接在一起，以创建数据块链或区块链。
区块链的特别创新和重要之处在于它在点对点 (P2P) 网络中分散或分散。没有单一的服务器容纳数字货币区块链来跟踪每个人如何花钱。相反，很多人都有数字货币区块链的记录。任何人都可以免费下载当前数据并与其他用户共享。
这使得区块链上的任何东西都非常难以破解，如果不是不可能的话。每个拥有区块链信息副本的人也在区块链上与其他人共享，每个人都在更新他们的记录以包含最新信息。如果有人想修改区块链，说他们有 100 万比特币，网络上的其他人都会说，“不，这看起来不对”，并会拒绝该数据无效。区块链网络的去中心化和不变性使其成为数字货币的完美基础。
矿工的任务就是验证交易，而解决的难题是加密哈希函数。根据 Ameer Rosic 的说法，哈希函数“本质上是没有密钥的单向加密”，
谁还解释说，在这些类型的谜题上作弊是不可能的，因为没有比猜测更好的方法来解决它们。
为了猜测目标加密哈希（必须低于某个数字），比特币矿工首先生成“随机数”或仅使用一次的数字。为了比较这些数字，目标哈希是一个 64 位的十六进制数，即 256 位，而比特币挖掘中的随机数仅为 32 位。
如前所述，可开采的数字货币越少，开采的难度就越大。现在，一个随机数产生一个可行的散列的机会，例如一个低于指定数字的，不到 2 万亿分之一——换句话说，比赢得彩票要难得多。然而，当矿工成功时，他们已经执行了工作量证明（PoW），这是一份数据，“证明”他们提供的东西是困难、耗时和昂贵的。这允许网络上的其他人验证他们的努力是否有效。比特币使用一种称为“hashcash”的工作证明来奖励矿工。
这些被描述为处于“军备竞赛”中的工业采矿业务面临三个主要竞争领域：位置、电价以及计算机硬件和软件的组合。
地点
首先需要了解的基本概念是，全年365天24小不间断的设备运行会消耗大量电力。这会产生大量的热量。在大多数传统数据中心（即非采矿数据中心）中，昂贵的冷却系统可确保系统保持在最佳温度。然而，为了保持竞争力，工业采矿设施需要尽可能提高效率，即使是在冷却采矿机时也是如此。在加拿大，数字货币挖矿设施的建造方式可以让北极风吹过设备区域，自然冷却它们，而不会消耗不必要的能源。
加拿大的能源基础设施也提供了竞争优势，我们将在下面介绍。量子宝石在加拿大境内投资设施的原因有很多：环境友好、效率提高、成本降低和竞争优势。
电价和能源消耗
电力在工业采矿作业的成功中起着巨大的作用。能源及其成本都可以决定采矿设施的成败。即使是高效的挖矿设备仍然消耗大量电力。投资者和其他数字货币爱好者对开采数字货币对环境的影响表示担忧。同样，为能源支付过高的价格对投资者来说可能是一个危险信号。
这也是量子宝石在加拿大投资设施的另一个原因，那里大量的可再生能源在保护大自然的同时降低了成本。水力发电和大量的天然气都使加拿大几乎可以完全使用可再生能源。高地和降水提供该国的水力发电，而大量的天然气井提供了充足的热能。
当然，硬件和软件在能源消耗中也起着主导作用。如今，仅仅位于最佳国家并不足以在数字货币挖矿军备竞赛中保持竞争力。
计算机硬件和软件
当使用如此惊人的电力时，数字货币矿业公司希望每千瓦时获得最大收益。这就是一流的软件和硬件发挥作用的地方。充分利用矿机消耗的电力需要硬件和软件。
数字货币挖矿硬件迅速从CPU挖矿到GPU挖矿，再到ASIC挖矿。但从比特币领域来说，第一批用于挖掘比特币的 ASIC比 GPU 挖掘效率高 100 倍，在一个月内逐步淘汰了 GPU 挖掘。对于以太坊来说，显卡挖矿依旧是主力军，恐怕在今后数年也将会是。
同时，充足的货运也是一个关键因素，受COVID-19疫情的影响，全新芯片的供应量都一直处于短缺状态。
量子宝石与数个国家的数个总供应商签约供货合同，充足的货源代表着充分的矿力。
These industrial mining operations described as being in an "arms race," face three main areas of competition: location, electricity prices, and a combination of computer hardware and software.
1. Location
First of all, the basic concept that needs to be understood is that 24 hours a day, 365 days a year, uninterrupted equipment operation consumes a lot of electricity. This generates a lot of heat. In most traditional data centers (ie, non-mining data centers), expensive cooling systems can ensure that the system is kept at an optimal temperature. However, to remain competitive, industrial mining facilities need to be as efficient as possible, even when cooling mining machines. In Canada, the construction of digital currency mining facilities allows the cold temperatures to blow through the equipment area, cooling them naturally without consuming unnecessary energy. Canada's energy infrastructure also provides a competitive advantage, which we will describe below. There are many reasons why Quantum Gems invests in facilities in Canada: environmental friendliness, efficiency improvement, cost reduction, and competitive advantage.
2. Electricity price and energy consumption
Electricity plays a huge role in the success of industrial mining operations. Energy and its cost can determine the success or failure of a mining facility. Even high-efficiency mining equipment still consumes a lot of electricity. Investors and other digital currency enthusiasts expressed concern about the environmental impact of mining digital currency. Similarly, paying too high a price for energy can be a red flag for investors. This is another reason why Quantum Gems invests in facilities in Canada, where a large amount of renewable energy reduces costs while protecting nature. Hydroelectric power and a large amount of natural gas have made Canada almost completely use renewable energy. Highlands and precipitation provide the country's hydroelectric power generation, while a large number of natural gas wells provide sufficient thermal energy. Of course, hardware and software also play a leading role in energy consumption. Today, being in the best country is not enough to stay competitive in the digital currency mining arms race.
3. Computer hardware and software
When using such a large amount of electricity, digital currency mining companies hope to get the most benefit per kilowatt-hour. This is where first-class software and hardware come into play. Full use of the electricity consumed by the mining machine requires hardware and software. Digital currency mining hardware quickly changed from CPU mining to GPU mining to ASIC mining. But from the perspective of Bitcoin, the first batch of ASICs used to mine Bitcoin was 100 times more efficient than GPU mining, and GPU mining was phased out within a month. For Ethereum, graphics card mining is still the main force, and will be in the next few years. At the same time, sufficient freight is also a key factor. Affected by the COVID-19 epidemic, the supply of new chips has been in short supply.
Quantum Gem has signed supply contracts with several general suppliers in several countries. Sufficient supply represents sufficient mineral power.
GPU mining
As we mentioned, GPU is the standard hardware in personal computers. This means that they are suitable for standard motherboards. Due to its wide range of uses, competition among manufacturers is still fierce, such as NVIDIA and AMD. This has led to increasingly powerful GPUs, all of which are available at reasonable prices. The GPU can be easily replaced and upgraded in the miner, thus realizing a low-cost rig. Unlike ASICs, after upgrading GPUs in the mining equipment, the previously used video cards can resell a large portion of their value. This is because the versatility of the GPU meets a large number of needs. BIOS upgrade is also part of the GPU mining game, which can significantly improve performance even without changing the hardware. GPU has many uses in the field of digital currency. GPU can be used to mine a variety of different digital currencies, even in line with the evolving company strategy, without the need to replace hardware. Some digital currencies, such as Monero, prevent ASIC mining by implementing consistent updates, which makes it impossible or costly to create ASICs for the network. On the other hand, GPUs are not as powerful or efficient as ASICs and are usually larger. In addition, some digital currencies cannot be mined for any considerable profit using only GPUs. GPUs also need more power to run, but this can be offset by running in low-cost energy fields.
ASIC mining
Only a few companies create ASICs, which makes competition low and prices high. ASIC mining usually requires a large initial investment to obtain any profit opportunities. The ASIC hardware must be created specifically for the type of coin it is mined. For example, Bitcoin ASICs are worthless for mining Litecoin, and vice versa. This means that any change in the company or mining strategy requires investment in new hardware. Similarly, when a new ASIC version is released for coins, the necessary hardware upgrades can be very expensive. Due to the need to upgrade, ASICs have a relatively short lifespan compared with GPUs. Although ASIC is still the latest product in its series, it provides the highest hash rate for the coins it is mining. ASICs also provide more efficient power consumption, leading to higher profitability. In addition, ASICs are usually much smaller than GPUs because they do not require standard hardware. This allows mining companies to accommodate a large amount of mining equipment in a relatively small space compared to the space required by GPU miners. When the equipment needs to be upgraded, the entire ASIC needs to be replaced. Old ASICs can usually only be sold at a fraction of the original price. Since ASIC has no other purpose and can only mine specific coins, the product is almost useless after the updated version is released. Obsolescence has always been a problem with ASICs, not only because of the new version of the system but also because of the possibility of changes in hashing or calculation algorithms on the network. This is how Monero prevents ASIC competition. They vowed to implement small algorithm changes at least every six months to create a cost-preventing environment for potential ASIC creators of the network. Bitmain developed an ASIC miner for Monero, but the network immediately released a change that made the ASIC obsolete
GPU挖矿
正如我们所提到的，GPU 是个人计算机中的标准硬件。这意味着它们适合标准主板。由于其用途广泛，制造商之间的竞争仍然很激烈，例如 NVIDIA 和 AMD。这导致功能越来越强大的 GPU，所有这些都以合理的价格提供。
GPU 可以在矿机内轻松更换和升级，从而实现低成本钻机。与 ASIC 不同，在升级采矿设备中的 GPU 后，它们所在的视频卡可以转售其价值的很大一部分。这是因为 GPU 的多功能性满足了大量需求。BIOS 升级也是 GPU 挖掘游戏的一部分，即使不更换硬件也可以显着提高性能。
GPU 在数字货币领域有多种用途。GPU 可用于挖掘各种不同的数字货币，甚至符合不断发展的公司战略，无需更换硬件。
一些数字货币，例如门罗币，通过实施一致的更新来阻止 ASIC 挖掘，这使得为网络创建 ASIC 变得不可能或成本太高。
另一方面，GPU 不如 ASIC 强大或高效，而且通常尺寸更大。此外，仅使用 GPU 无法开采某些数字货币以获得任何可观的利润。GPU 也需要更多的电力来运行，但这可以通过在低成本能源领域运行来抵消。
ASIC挖矿
只有少数公司创建 ASIC，这使得竞争低，价格高。从 ASIC 挖矿开始通常需要大量的初始投资，才能获得任何盈利机会。
ASIC 硬件必须专门为其开采的硬币类型创建。例如，比特币 ASIC 对于挖掘莱特币实际上毫无价值，反之亦然。这意味着公司或采矿战略的任何变化都需要投资新硬件。同样，当针对硬币发布新的 ASIC 版本时，必要的硬件升级可能会非常昂贵。由于需要升级，与 GPU 相比，ASIC 的寿命相对较短。
虽然 ASIC 仍然是其系列中的最新产品，但它为其正在开采的硬币提供了最高的哈希率。ASIC 还提供更高效的功耗，从而带来更高的盈利能力。此外，ASIC 通常比 GPU 小得多，因为它们不需要标准硬件。与 GPU 矿工所需的空间相比，这允许采矿公司在相对较小的空间内容纳大量采矿设备。
当需要升级设备时，需要更换整个 ASIC。旧的 ASIC 通常只能以原价的一小部分出售。由于 ASIC 没有其他目的，只能开采特定的硬币，因此在发布更新版本后，该产品几乎毫无用处。过时一直是 ASIC 的一个问题，这不仅是因为系统的新版本，还因为网络上的散列或计算算法有可能发生变化
这就是门罗币防止 ASIC 竞争的方式。他们发誓至少每六个月实施一次小的算法更改，为网络的潜在 ASIC 创建者创建一个成本预防环境。比特大陆为 Monero 开发了一个 ASIC 矿工，但网络立即发布了一项更改，使 ASIC 过时
Proof of Work, usually abbreviated as PoW, is the original traditional consensus algorithm used on blockchain networks. Proof of work is the data created when miners solve a block to "prove" that they put in resource-intensive work to generate random numbers to verify transactions and add new data blocks to the blockchain. If the miner is the first person to come up with the correct answer, they will be rewarded for guessing a random number. Miners are rewarded for the work they do for the network, that is, verifying transactions, a process that prevents double-spending. Miners also benefit from transaction fees.
Proof of stake, usually abbreviated as PoS, is newer than the original proof of work in the blockchain field. PoS is an alternative system for verifying transactions in a blockchain environment. It is not based on the amount of calculation work done by the miners but requires the person verifying the transaction to hold a specific number of specific digital currency units-the proof of equity in the currency. In PoS, miners mine blocks to discover new coins and verify transactions. In the proof-of-stake system, counterfeiters forge or mint new blocks while verifying transactions.
