⑴ 区块链钱包有什么作用呢，有能说明白的嘛

区块链钱包的本质是一个私钥，它是一个随机的哈希值字符串，拥有了私钥就拥有了该钱包的使用权。如果按照私钥存储方式可划分为：冷钱包和热钱包
冷钱包是指网络不能访问到你私钥的钱包，一般会拿笔记本记录，虽然免去被黑客盗取私钥的风险，但是也有可能遗失。
热钱包是指互联网能购访问你私钥的钱包。热钱包往往是在线钱包的形式，不容易遗失，但是也同样具有风险。

⑵ 数字资产钱包有哪些

数字资产钱包有imtoken、比特派、库神、虎符等，下面详细说说：

谈起区块链数字资产，就离不开数字钱包，随着区块链技术的不断发展，数字钱包在区块链生态中起着越来越重要的作用，早期只有转账、存储、收款等基础功能，如今通过数字钱包不但可以进行资产管理，而且还可以进行数字资产理财、数字资产交易、为公链 DApp 导流等。数字钱包已成为进入区块链世界的重要入口。

平时我们经常听到热钱包、冷钱包以及硬件钱包等，它们到底有什么区别呢？根据不同的标准，可以把数字钱包作不同的分类，下面我们一起聊聊常见的几种数字钱包分类方法。

03根据钱包的去中心化程度分类

根据钱包的去中心化程度不同，可以把数字钱包分为全节点钱包、轻节点钱包和中心化钱包。

全节点钱包是指同步了区块链上所有数据的钱包。例如，比特币的全节点数据已达到了几百G，比特币全节点钱包需要同步所有的数据，全节点钱包虽然占据存储空间比较大，但可以实现完全去中心化。

轻节点钱包则是依赖于区块链上其他全节点钱包，仅同步与自己相关的数据，从而实现了部分去中心化。例如我们常用的比特币钱包就是轻节点钱包，在使用这些钱包时，只下载与自己比特币账号相关的数据，下载几百G的数据也不现实。

中心化钱包是指所有的数据均从自己的中心化服务器获得，数据依赖钱包服务商自己的账本，它的交易效率很高，基本可以实现实时到账，例如我们在交易平台的钱包就是中心化钱包。

⑶ 电脑上面说的挖矿是什么意思

挖矿：即比特币挖矿，是一种利用电脑硬件计算出比特币的位置并获取的过程。

⑷ 数字货币的钱包有什么用

数字货币的钱包就是硬件钱包是指将数字资产私钥单独储存在一个芯片中，与互联网隔离，即插即用。硬件钱包不能保证100%安全，比如某Geek获取你的硬件钱包即时不知道你的私钥，也有可能暴力破解。只是相对于其他保管手段，这是最安全的储存手段之一。

不少国内外区块链创业者看好这一领域的发展，于是开始打造更多的硬件钱包。在交易所被大量盗币、软件钱包不时失窃的情况下，硬件钱包被不少投资者视为最后一道护城河。

硬件钱包是否安全

硬件钱包不能保证100%安全，比如某Geek获取你的硬件钱包即时不知道你的硬件钱包，也有可能暴力破解。只是相对于其他保管手段，这是最安全的储存手段之一。

当然，也有例外，比如你脑力无极限，且过目不忘。那存哪都不如存自己的脑子里。

⑸ 比特币打同一个钱包哈希码是一样吗

4、去中心化

去中心化是一种现象或结构，必须在拥有众多节点的系统中或在拥有众多个体的群中才能出现或存在。节点与节点之间的影响，会通过网络而形成非线性因果关系。

5、共识机制

共识机制是通过特殊节点的投票，在很短的时间内完成对交易的验证和确认；对一笔交易，如果利益不相干的若干个节点能够达成共识，我们就可以认为全网对此也能够达成共识。

6、Pow——工作量证明

Proofof Work，是指获得多少货币，取决于你挖矿贡献的工作量，电脑性能越好，分给你的矿就会越多。

7、PoS——权益证明

Proofof Stake，根据你持有货币的量和时间进行利息分配的制度，在POS模式下，你的“挖矿”收益正比于你的币龄，而与电脑的计算性能无关。

8、智能合约

智能合约是一种旨在以信息化方式传播、验证或执行合约的计算机协议。智能合约允许在没有第三方的情况下进行可信交易，这些交易可追踪且不可逆转。

9、时间戳

13、PrivateKey——私钥

私钥是一串数据，它是允许你访问特定钱包中的令牌。它们作为加密货币，除了地址的所有者之外，都被隐藏。

14、PublicKey——公钥

是和私钥成对出现的，公钥可以算出币的地址，因此可以作为拥有这个币地址的凭证。

15、矿机

尝试创建区块并将其添加到区块链上的计算设备或者软件。在一个区块链网络中，当一个新的有效区块被创建时，系统一般会自动给予区块创建者（矿机）一定数量的代币，作为奖励。

16、矿池

是一个全自动的挖矿平台，使得矿机们能够贡献各自的算力一起挖矿以创建区块，获得区块奖励，并根据算力贡献比例分配利润（即矿机接入矿池—提供算力—获得收益）。

17、公有链

完全开放的区块链，是指任何人都可读取的、任何人都能发送交易且交易能获得有效确认的、全世界的人都可以参与系统维护工作，任何人都可以通过交易或挖矿读取和写入数据。

18、私有链

19、联盟链

共识机制由指定若干机构共同控制的区块链。

20、侧链

楔入式侧链技术（pegged sidechains），它将实现比特币和其他数字资产在多个区块链间的转移，这就意味着用户们在使用他们已有资产的情况下，就可以访问新的加密货币系统。

21、跨链技术

跨链技术可以理解为连接各区块链的桥梁，其主要应用是实现各区块链之间的Atom交易、资产转换、区块链内部信息互通，或解决Oracle的问题等。

22、硬分叉

区块链发生永久性分歧，在新共识规则发布后，部分没有升级的节点无法验证已经升级的节点生产的区块，通常硬分叉就会发生。

23、软分叉

当新共识规则发布后，没有升级的节点会因为不知道新共识规则下，而生产不合法的区块，就会产生临时性分叉。

24、Hash——哈希值

一般翻译做”散列”，也有直接音译为”哈希”的。简单的说就是一种将任意长度的消息压缩到某一固定长度的消息摘要的函数。

25、主链

主链一词源于主网（，相对于测试网），即正式上线的、独立的区块链网络。

对币圈“行话”还不了解的小伙伴，赶快来学习一下：

1、法币是什么？

法币是法定货币，是由国家和政府发行的，只有政府信用来做担保，如人民币、美元等等。

2、token是什么？

token，通常翻译成通证。Token是区块链中的重要概念之一，它更广为人知的名字是“代币”，但在专业的“链圈”人看来，它更准确的翻译是“通证”，代表的是区块链上的一种权益证明，而非货币。

Token的三个要素

一是数字权益证明，通证必须是以数字形式存在的权益凭证，代表一种权利、一种固有和内在的价值；

二是加密货币，通证的真实性、防篡改性、保护隐私等能力由加密货币学予以保障；

三是能够在一个网络中流动，从而随时随地可以验证。

⑴ What is the function of a blockchain wallet? Can anyone explain it clearly?

The essence of a blockchain wallet is a private key, which is a random hash value string. , having the private key gives you the right to use the wallet. According to the private key storage method, it can be divided into: cold wallet and hot wallet
Cold wallet refers to a wallet where the network cannot access your private key. Generally, a notebook is used to record it, although it avoids the risk of the private key being stolen by hackers. , but it may also be lost.
A hot wallet refers to a wallet that has access to your private key via the Internet. Hot wallets are often in the form of online wallets, which are not easy to lose, but are also risky.

⑵ What are the digital asset wallets?

Digital asset wallets include imtoken, Bitpie, Kushen, Hufu, etc. Let’s talk about them in detail below:

Talk about the area Blockchain digital assets are inseparable from digital wallets. With the continuous development of blockchain technology, digital wallets play an increasingly important role in the blockchain ecosystem. In the early days, they only had basic functions such as transfer, storage, and collection. , now not only asset management can be carried out through digital wallets, but also digital asset financial management, digital asset transactions, and public chain DApp diversion can be carried out. Digital wallets have become an important entry point into the world of blockchain.

We often hear about hot wallets, cold wallets, hardware wallets, etc. What are the differences between them? Digital wallets can be classified differently according to different standards. Let’s talk about several common digital wallet classification methods.

03 Classification according to the degree of decentralization of wallets

According to the different degrees of decentralization of wallets, digital wallets can be divided into full-node wallets, light wallets Node wallet and centralized wallet.

A full node wallet refers to a wallet that synchronizes all data on the blockchain. For example, Bitcoin's full node data has reached hundreds of gigabytes. The Bitcoin full node wallet needs to synchronize all data. Although the full node wallet occupies a relatively large storage space, it can achieve complete decentralization.

Light node wallets rely on other full node wallets on the blockchain and only synchronize data related to themselves, thereby achieving partial decentralization. For example, our commonly used Bitcoin wallets are light node wallets. When using these wallets, you only download the data related to your own Bitcoin account, and it is not realistic to download hundreds of gigabytes of data.

A centralized wallet means that all data is obtained from its own centralized server. The data relies on the wallet service provider's own ledger. Its transaction efficiency is very high and it can basically achieve real-time payment. For example, we are in The wallet of the trading platform is a centralized wallet.

⑶ What does mining mean when it comes to computers

Mining: Bitcoin mining is a process that uses computer hardware to calculate the location of Bitcoin and obtain it.

⑷ What is the use of a digital currency wallet?

A digital currency wallet is a hardware wallet that refers to the transfer of digital assets.The private key is stored separately in a chip, isolated from the Internet, and is plug-and-play. Hardware wallets cannot guarantee 100% security. For example, if a Geek obtains your hardware wallet without knowing your private key, it may be cracked by brute force. But compared to other storage methods, this is one of the safest storage methods.

Many domestic and foreign blockchain entrepreneurs are optimistic about the development of this field, so they began to build more hardware wallets. With a large number of coins being stolen from exchanges and software wallets being stolen from time to time, hardware wallets are regarded by many investors as the last moat.

(4) What is the cold wallet hash code? Extended reading:

Is the hardware wallet safe?

Hardware wallets cannot guarantee 100 % safe. For example, if a Geek obtains your hardware wallet without knowing your hardware wallet, it is possible to crack it through brute force. But compared to other storage methods, this is one of the safest storage methods.

Of course, there are exceptions. For example, your brain has no limits and you have a photographic memory. It's better to store it anywhere than in your own mind.

⑸ Is the hash code of the same Bitcoin wallet the same?

⑹ What are some professional terms in the currency circle

26 explanations of common terms in the blockchain industry

1. Blockchain ——Blockchain

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. is a shared distributed ledger where transactions are permanently recorded through appended blocks.

2. Block——Block

In the Bitcoin network, data will be permanently recorded in the form of files. We call these files blocks. A block is a set of records of some or all of the latest Bitcoin transactions that have not been recorded by other previous blocks.

3. Node - A copy of the ledger operated by participants in the blockchain network.

4. Decentralization

Decentralization is a phenomenon or structure that must appear or exist in a system with many nodes or in a group with many individuals. The influence between nodes will form a non-linear causal relationship through the network.

5. Consensus mechanism

The consensus mechanism is to complete the verification and confirmation of transactions in a very short time through the voting of special nodes; for a transaction, if the interests are irrelevant If several nodes can reach a consensus, we can think that the entire network can also reach a consensus on this.

6. Pow - Proof of Work

Proof of Work refers to how much currency you get, depending on the workload you contribute to mining. The better the computer performance, the more money will be allocated to you. There will be more mines.

7. PoS - Proof of Stake

Proof of Stake, according toThe interest distribution system is based on the amount and time you hold the currency. In POS mode, your "mining" income is proportional to the age of your currency and has nothing to do with the computing performance of your computer.

8. Smart Contract

Smart contract is a computer protocol designed to spread, verify or execute contracts in an information-based manner. Smart contracts allow trusted transactions to be made without third parties, which are traceable and irreversible.

9. Timestamp

Timestamp refers to a string or encoded information used to identify the recorded time and date. The international standard is ISO 8601.

10. Turing completeness

Turing completeness refers to the ability of a machine to perform any calculation that any other programmable computer can perform.

11. Dapp - decentralized application

It is an open source application that runs automatically and stores its data on the blockchain in the form of cryptocurrency tokens. Form incentives and operate with a protocol that displays proof of value.

12. DAO - Decentralized Autonomous Organization

It can be thought of as a company that operates without any human intervention and hands all forms of control to a set of uncontrollable entities. Broken business rules.

13. PrivateKey - Private Key

A private key is a string of data that allows you to access a token in a specific wallet. They, as cryptocurrencies, are hidden except from the owner of the address.

14. PublicKey——Public key

It appears in pairs with the private key. The public key can calculate the address of the currency, so it can be used as a certificate for owning the address of the currency.

15. Mining machine

A computing device or software that attempts to create blocks and add them to the blockchain. In a blockchain network, when a new valid block is created, the system will generally automatically give the block creator (mining machine) a certain number of tokens as a reward.

16. Mining pool

It is a fully automatic mining platform that allows miners to contribute their own computing power to mine together to create blocks and obtain block rewards. And the profits are distributed according to the proportion of computing power contribution (that is, the mining machine is connected to the mining pool - provides computing power - obtains income).

17. Public chain

A completely open blockchain refers to a fully open blockchain that can be read by anyone, anyone can send transactions, and transactions can be effectively confirmed. People around the world can participate in system maintenance, and anyone can read and write data through transactions or mining.

18. Private chain

A blockchain where write permission is only for a certain organization or a specific few objects. Read permissions can be open to the outside world, or restricted to any degree.

19. Alliance chain

The consensus mechanism is a blockchain jointly controlled by a number of designated institutions.

20. Side chain

Wedge side chain technology (pegged sidechains), which will enable the transfer of Bitcoin and other digital assets across multiple blockchains, meaning users can access new cryptocurrency systems while using their existing assets.

21. Cross-chain technology

Cross-chain technology can be understood as a bridge connecting various blockchains. Its main application is to realize Atom transactions, asset conversion, and partitioning between blockchains. Information exchange within the blockchain, or solving Oracle problems, etc.

22. Hard fork

The blockchain has a permanent divergence. After the new consensus rules are released, some nodes that have not been upgraded cannot verify the blocks produced by the upgraded nodes. Usually a hard fork happens.

23. Soft fork

When the new consensus rules are released, nodes that have not been upgraded will produce illegal blocks because they do not know the new consensus rules, which will cause Temporary forks.

24. Hash——Hash value

Generally translated as "hash", there are also direct transliterations as "hash". Simply put, it is a function that compresses a message of any length into a message digest of a fixed length.

25. Main chain

The term main chain comes from the main network (relative to the test network), which is an independent blockchain network that is officially online.

For those who don’t understand the “jargon” of the currency circle, come and learn it quickly:

1. What is legal currency?

Legal currency is legal tender, issued by the country and the government, and is only guaranteed by government credit, such as RMB, US dollars, etc.

2. What is token?

Token, usually translated as pass. Token is one of the important concepts in the blockchain. It is more commonly known as "token", but in the eyes of professional "chain circle" people, its more accurate translation is "pass", which represents the area. A proof of stake on the blockchain, not a currency.

The three elements of Token

The first is digital proof of rights and interests. The token must be a certificate of rights and interests in digital form, representing a right and an inherent and intrinsic value;

The second is cryptocurrency. The authenticity, tamper resistance, privacy protection and other capabilities of the token are guaranteed by cryptography;

The third is the ability to flow in a network, so that It can be verified anytime and anywhere.

3. What is position building?

Building a position in the currency circle is also called opening a position, which refers to a trader’s new purchase or sale of a certain amount of digital currency.

4. What is stud?

Cryptocurrency stud means investing all the principal.

5. What is an airdrop?

Airdrops are currently a very popular cryptocurrency marketing method. In order to provide potential investors and people who are passionate about cryptocurrency with information about the token, the token team will conduct frequent airdrops.

6. What is lock-up?

Lock-up generally means that after investors buy and sell contracts, when the market trend is opposite to their own operations, they open a new position opposite to their original position. It is also called lock-in, lock-up, or even euphemistically called butterflies flying together.

7. What is candy?

Cryptocurrency candies are digital coins that are distributed to users for free when various digital currencies are first issued and ICO. They are a kind of momentum and promotion for the project itself by the issuer of the virtual currency project.

8. What is a break?

Break refers to falling below, and hair refers to the issuance price of digital currency. A currency circle break means that a certain digital currency falls below the issuance price.

9. What is private equity?

Cryptocurrency private placement is a way to invest in cryptocurrency projects, and it is also the best way for cryptocurrency project founders to raise funds for platform operations.

10. How do you look at the K-line chart?

K-line charts (Candlestick Charts) are also called candle charts, Japanese lines, Yin-Yang lines, stick lines, red and black lines, etc. The commonly used term is "K-line". It is plotted as the opening, high, low and closing prices for each analysis period.

11. What is hedging?

Generally, hedging is to conduct two transactions at the same time that are related to the market, opposite in direction, of equal quantity, and with profits and losses offsetting. In the futures contract market, buy positions of the same quantity but in different directions. When the direction is determined, close the position in the opposite direction and retain the positive direction to gain profits.

12. What is a position?

Position is a market agreement that commits to buying and selling the initial position of a contract. Those who buy the contract are long and are in a position to expect an increase; those who sell the contract are short and are in a position to expect a decrease.

13. What are the benefits?

Good news: It refers to news that a currency has received mainstream media attention, or that a certain technology application has made breakthrough progress, which is conducive to stimulating price increases. This is called good news.

14. What are the disadvantages?

Bad news: news that causes currency prices to fall, such as Bitcoin technical problems, central bank suppression, etc.

15. What is rebound?

The price adjustment phenomenon in which currency prices rebound due to falling too fast in a downward trend. The recovery is smaller than the decline.

16. What is leverage?

Leveraged trading, as the name suggests, is to use small amounts of funds to invest several times the original amount, in the hope of obtaining multiple returns or losses relative to the fluctuations in the investment target.
