A. 冷钱包、热钱包分别是什么东西啊

冷钱包就是等于把你的私钥和网络隔绝了，现在冷钱包也可以放卡里面，更安全，我用的就是酷宝冷钱包

B. 冷钱包和热钱包的区别

1.冷钱包不接触网络，采用全新的技术模式保证冷端硬件永不触网，使用多重加密防护体系保证核心资产，全冷环境彻底杜绝私钥泄露风险。
2.热钱包较冷钱包使用便利，但安全性远远比不上冷钱包。
拓展资料：
1.冷钱包：是指由提供区块链数字资产安全存储解决方案的信息技术公司研发的比特币存储技术。冷钱包集数字货币存储、多重交易密码设置、发布最新行情与资讯、提供硬分叉解决方案等功能于一身，且运用二维码通信让私钥永不触网，能有效防止黑客窃取。
2.热钱包：可以让用户在任何浏览器和移动设备上使用比特币，通常它还提供一些额外功能，使用户使用比特币时更加方便。但选择热钱包必须慎重，因为其安全性受到服务商的影响。
3.冷钱包的优点
（1）部分冷钱包支持币种丰富。
（2）私钥不触网，不用担心受到黑客和木马的攻击。
（3）冷钱包的币采取分散存储方式，每个地址存确定数量的币。
（4）某个私钥一旦汇币到线上以后，即作废，永不再使用。
4.热钱包的优点
（1）它们允许软件开发人员采用自己的应用程序。
（2）它可以方便地提取加密货币，而不需要像支持“交易所”这样第三方用户访问私钥。
（3）它可以防止黑客利用其自定义保护方法进行攻击，如不同的确认程序来提高取款和两步登录。
5.冷钱包的主要优点是安全，但缺点也很明显，那就是操作不方便，尤其是转出Token时。相比起来热钱包在安全方面就稍显逊色，但操作方便。安全永远是相对的，从黑客、木马病毒等角度来看，冷钱包的安全性比热钱包更高。冷钱包的操作门槛也相对比较高，便捷性不如热钱包，因此冷钱包主要是加密资产较大的机构或者个人在使用。随着数字资产金融市场的高速发展，数字资产的市场参与者与交易者数量的急剧攀升，与此同时，诸如数字资产被盗、数字资产被随意挪用、数字资产投资风险高等痛点也被完全的暴露了出来。因此，钱包作为区块链产业必不可少的一环，随着区块链产业的发展和扩张也呈现加速现象。

C. 冷钱包和助记词硬件是怎么做的

通过可信任的助记词、增加灵活性。
软件冷钱包，不同于硬件冷钱包，软件冷钱包使用纯软件的方式实现冷钱包功能。用户需要使用两部手机，其中一部永久离线，作为冷钱包存储私钥（助记词）。另一部联网，作为观察钱包使用。软件冷钱包和硬件冷钱包实现同样的功能，安全级别类似。但是它们有一些显著的区别：软件冷钱包可以使用闲置手机，没有额外的硬件；硬件冷钱包通过数据线或蓝牙传输数据，而软件冷钱包通过扫描二维码。
可信任的助记词：软件冷钱包可以实现更彻底的去信任（即不需要信任软件开发者），用户可以自行证明其钱包的绝对安全性。在资产安全中，首当其冲的是助记词的安全。而在助记词的安全中，首要确认是助记词生成的随机性。如果您使用了一个作恶的硬件厂商（或者有 bug）的硬件钱包，您可能在第一步就已经陷落了。
在使用软件冷钱包时，你可选择信任软件，让其帮助您生成助记词。也可以选择不信任软件，自行在它处生成助记词。因此，软件冷钱包的助记词的安全性高于硬件冷钱包。
软件冷钱包比硬件冷钱包更加灵活。通常软件冷钱包可以实现比硬件冷钱包更加复杂的功能。软件冷钱包的灵活性，也让其在资产的恢复方面也更加有优势。如果您的硬件钱包损坏，需要购买（同一厂商）的硬件，进行硬件恢复。而使用软件冷钱包，则没有这样的顾虑。
拓展资料：
目前市场上，虽然主要的冷钱包产品依然是以硬件冷钱包为主，但是它们正在受到软件冷钱包的冲击。硬件冷钱包： Ledger 是最知名的硬件冷钱包方案提供商； Trezor 是另一个知名的硬件冷钱包提供商；软件冷钱包：Ownbit 是最早实现软件冷钱包方案的钱包，也是支持冷钱包币种最多的钱包之一； Parity Signer 是 Parity 出品的以太坊软件冷钱包；未来事物发展的方向永远是化繁为简。越来越多的冷钱包正在以软件的方式实现。

D. 什么是冷钱包

通俗来说冷钱包就是将数字货币进行离线下储存的钱包，玩家在一台离线的钱包上面生成数字货币地址和私钥，再将其保存起来。而冷钱包是在不需要任何网络的情况下进行数字货币的储存，因此黑客是无法进入钱包获得私钥的。

E. 冷钱包如何使用

F. 冷钱包有什么用

G. 什么是冷钱包（离线钱包）

冷钱包又称离线钱包，包括硬件钱包，纸钱包和脑钱包。通俗可理解为在没有联网环境下使用的钱包。硬件钱包不一定百分百就是冷钱包。我们说的冷钱包是指私钥和签名这个动作是永远离线的，以这个来界定他是冷钱包。所以说冷钱包也有可能是以硬件形态来形成，也有可能是以一个软件来形成。
所以说在很多钱包app里都支持冷热分离的操作的。

H. 冷钱包怎么创建

简便生成冷钱包，需要工具:手机+内存卡。
步骤如下:
第1步:找一部不用的手机或专门用作钱包的手机，手机恢复出厂设置;
第2步:断开手机网络;
第3步:安装imtoken钱包;
第4步:用imtoken钱包创建钱包;
第5步:将私钥备份至内存卡，手抄好助记词多重备份，并导出钱包地址。
拓展资料：
一、冷钱包好处
冷钱包永不联网，不能被网络访问，因而避免了黑客盗取私钥的风险，相比热钱包更安全。
价值投资者，把冷钱包放进保险柜，避免放在交易所，时不时“手贱"操作一把。
当然，如果需要经常用来交易或频繁交易的，当资产较大的时候，冷热钱包配合使用，经常需要交易的用热钱包储存;无需进程交易的，用冷钱包储存。
二、冷钱包《Cold wallet) ，与热钱包相对应，也称离线钱包或者断网钱包，区块链钱包种类之一，意指网络不能访问到用户私钥的钱包。
冷钱包通常依靠“冷设备（不联网的电脑、手机等〉确保比特币私钥的安全，运用二维码通信让私钥不触网，避免了被黑客盗取私钥的风险，但是也可能面临物理安全风险（比如电脑丢失，损坏等〉。
三、基本概念
钱包就是存储和使用数字货币的工具，一个币对应一个钱包。用来存储币种，或者"交易币种。
比特币钱包使用户可以检查、存储、花费其持有的比特币，其形式多种多样，功能可繁可简，它可以是遵守比特币协议运行的各种工具，如电脑客户端、手机客户端、网站服务、专用设备，也可以只是存储著比特币私密密钥的介质，如一张纸、一段暗号、一个U盘、一个文本文档，因为只要掌握比特币的私密密钥，就可以处置其对应地址中包含的比特币。比特币无法存入一般的银行账户，交易只能在比特币网络上进行，使用前需下载客户端或接入线上网络。
冷钱包是指由提供区块链数字资产安全存储解决方案的信息技术公司研发的比特币存储技术。库神冷钱包集数字货币存储、多重交易密码设置、发布最新行情与资讯、提供硬分叉解决方案等功能于一身，且运用二维码通信让私钥永不触网，能有效防止黑客窃取。

A. What are cold wallets and hot wallets?

Cold wallets isolate your private keys from the network. Now cold wallets can also be placed in cards, which is safer. , I use Kubao cold wallet

B. The difference between cold wallet and hot wallet

1. The cold wallet does not contact the network and adopts a new technical model to ensure that the cold end hardware is always available. Do not touch the Internet, use multiple encryption protection systems to protect core assets, and completely eliminate the risk of private key leakage in a completely cold environment.
2. Hot wallets are more convenient to use than cold wallets, but are far less secure than cold wallets.
Extended information:
1. Cold wallet: refers to the Bitcoin storage technology developed by an information technology company that provides secure storage solutions for blockchain digital assets. The cold wallet integrates functions such as digital currency storage, multiple transaction password settings, publishing the latest market conditions and information, and providing hard fork solutions. It also uses QR code communication to prevent private keys from being exposed to the Internet, which can effectively prevent hackers from stealing.
2. Hot wallet: It allows users to use Bitcoin on any browser and mobile device. It usually also provides some additional features to make it more convenient for users to use Bitcoin. However, you must be careful when choosing a hot wallet because its security is affected by the service provider.
3. Advantages of cold wallets
(1) Some cold wallets support a wide range of currencies.
(2) The private key does not touch the Internet, so there is no need to worry about being attacked by hackers and Trojans.
(3) The coins in the cold wallet adopt a decentralized storage method, and each address stores a certain number of coins.
(4) Once a private key is transferred online, it will be invalid and will never be used again.
4. Advantages of hot wallets
(1) They allow software developers to adopt their own applications.
(2) It can easily withdraw cryptocurrencies without requiring third-party users to access private keys like supporting "exchanges".
(3) It prevents hackers from attacking using its custom protection methods, such as different confirmation procedures to improve withdrawals and two-step login.
5. The main advantage of cold wallet is security, but the disadvantage is also obvious, that is, it is inconvenient to operate, especially when transferring tokens. In comparison, hot wallets are slightly inferior in terms of security, but they are easy to operate. Security is always relative. From the perspective of hackers, Trojan viruses, etc., cold wallets are more secure than hot wallets. The operation threshold of cold wallets is also relatively high, and the convenience is not as good as hot wallets. Therefore, cold wallets are mainly used by institutions or individuals with large crypto assets. With the rapid development of the digital asset financial market, the number of market participants and traders of digital assets has increased sharply. At the same time, pain points such as theft of digital assets, random misappropriation of digital assets, and high risks of digital asset investment have also been completely eliminated. exposed. Therefore, as an indispensable part of the blockchain industry, wallets are accelerating with the development and expansion of the blockchain industry.

C. How are cold wallets and mnemonic hardware used?

Through trustworthy mnemonic phrases,Add flexibility.
Software cold wallet is different from hardware cold wallet. Software cold wallet uses pure software to realize the cold wallet function. Users need to use two mobile phones, one of which is permanently offline, as a cold wallet to store private keys (mnemonic phrases). The other one is connected to the Internet and used as an observation wallet. Software cold wallets and hardware cold wallets implement the same functions and have similar security levels. But they have some significant differences: software cold wallets can use idle mobile phones with no additional hardware; hardware cold wallets transmit data via data cable or Bluetooth, while software cold wallets scan QR codes.
Trusted mnemonic: Software cold wallet can achieve more complete trustlessness (that is, there is no need to trust the software developer), and users can prove the absolute security of their wallets by themselves. In asset security, the first thing that bears the brunt is the security of mnemonic phrases. In the security of mnemonic words, the first confirmation is the randomness of mnemonic word generation. If you use a hardware wallet from a rogue hardware manufacturer (or a buggy one), you may already be trapped on the first step.
When using a software cold wallet, you can choose to trust the software and let it help you generate a mnemonic phrase. You can also choose not to trust the software and generate the mnemonic phrase yourself elsewhere. Therefore, the security of the mnemonic phrase of software cold wallet is higher than that of hardware cold wallet.
Software cold wallets are more flexible than hardware cold wallets. Generally, software cold wallets can implement more complex functions than hardware cold wallets. The flexibility of software cold wallet also makes it more advantageous in asset recovery. If your hardware wallet is damaged, you need to purchase hardware (from the same manufacturer) for hardware recovery. With software cold wallets, there are no such concerns.
Extended information:
At present, although the main cold wallet products in the market are still hardware cold wallets, they are being impacted by software cold wallets. Hardware cold wallet: Ledger is the most well-known hardware cold wallet solution provider; Trezor is another well-known hardware cold wallet provider; Software cold wallet: Ownbit is the first wallet to implement software cold wallet solution and supports the most cold wallet currencies One of the wallets; Parity Signer is an Ethereum software cold wallet produced by Parity; The direction of future development of things is always to simplify the complex. More and more cold wallets are being implemented in software.

D. What is a cold wallet

G. What is a cold wallet (offline wallet)

Cold wallets are also called offline wallets, including hardware wallets, paper wallets and brain wallets. Generally speaking, it can be understood as a wallet used in a non-networked environment. Hardware wallets are not necessarily 100% cold wallets. The cold wallet we are talking about means that the private key and signature are always offline. This defines it as a cold wallet. Therefore, a cold wallet may be formed in the form of hardware, or it may be formed in the form of software.
So many wallet apps support hot and cold separation operations.

H. How to create a cold wallet

To easily generate a cold wallet, you need tools: mobile phone + memory card.
The steps are as follows:
Step 1: Find an unused mobile phone or a mobile phone specially used as a wallet, and restore the phone to factory settings;
Step 2: Disconnect the mobile phone network;
Step 3 :Install imtoken wallet;
Step 4: Create a wallet with imtoken wallet;
Step 5: Back up the private key to the memory card, copy the mnemonic phrase by hand for multiple backups, and export the wallet address.
Extended information:
1. Benefits of cold wallets
Cold wallets are never connected to the Internet and cannot be accessed by the network, thus avoiding the risk of hackers stealing private keys, and are safer than hot wallets.
Value investors, put the cold wallet in a safe, avoid placing it on the exchange, and operate it with "cheap hands" from time to time.
