1. 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

2. 自己的冷钱包地址怎么在别人的电脑上显示

一般来说把备份的wallet.dat覆盖新设备的Appdata（默认隐藏）某个bitcoin目录下的默认钱包文件即可，或者也可以在新客户端菜单栏“打开”备份的钱包。不过不建议通过备份还原BitcoinCore的wallet.dat钱包文件的方式保障比特币的安全，因为wallet.dat不仅包含私钥还包含交易记录，导致你可能每次交易后都需要备份一次，麻烦。而私钥只需备份一次多处就够了。没有wallet.dat文件，就不是比特币钱包么？如果你需要N个地址，可以选择分层确定性钱包HDWallet（这个只需要备份一串密语）而免去备份N个私钥的麻烦。而且如果在多个设备使用同一个地址的比特币的话（不建议这样做），注意要等A设备发币完全确认后，再在B设备同步完成这笔交易后，才能在B设备发币，不然A端没确认你B端又发的话可能“双花”导致第二笔交易发送失败。“警告！此交易存在多重支付”是什么意思？

3. 库神冷钱包是由什么公司推出的产品，靠谱吗

库神冷钱包是由北京库神信息技术有限公司推出的产品，这家公司主要是提供区块链数字货币安全存储解决方案的专业公司，我用了库神冷钱包之后觉得安全系数还是很高的，个人觉得比较靠谱。

4. CEO交易所他们交易使用冷钱包还是热钱包制度呢

他们是两者集合，金额较大的他们会建议适用冷钱包，金额小的就建议用热钱包，他们的冷热钱包制度是我目前为止，看到最完善的一个了。

5. 冷钱包存储技术是什么

比特币冷存储技术，CHIPS用的就是这个，不过这个平台更加高级，用了脑钱包技术，分散式存储，和其他的平台对比，安全性当然是最好的

6. 比特币冷钱包什么时候开发出来的

自比特币诞生就有了，最早的可以是纸钱包（即记在纸上），现在有比较功能齐全的电子设备，也不接触网络，即冷钱包。

7. 比特币冷钱包技术，求知道

是存储比特币的一种方法，保护比特币不被盗。CHIPS主要是接收比特币存储，其比特币冷存储技术很不错，很安全，

8. 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。

9. 什么是比特币冷钱包

指离线钱包，用户通常使用离线比特币钱包地址收发比特币，然后再离线使用钱包私钥进行确认签名。因此黑客是无从窃取冷钱包私钥的。由于相应多出了一个离线确认签名的环节，因此比特币冷钱包在使用上就没有热钱包那么方便快捷.。

1. 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

2. How to display my cold wallet address on other people’s computers

Generally speaking, the backup wallet.dat should be overwritten with the new device’s. Appdata (hidden by default) can be the default wallet file in a bitcoin directory, or you can "open" the backed up wallet in the menu bar of the new client. However, it is not recommended to back up and restore BitcoinCore’s wallet.dat wallet file to ensure the security of Bitcoin, because wallet.dat not only contains private keys but also transaction records, which may cause you to need to back it up after each transaction, which is troublesome. The private key only needs to be backed up once in multiple places. Without a wallet.dat file, wouldn’t it be a Bitcoin wallet? If you need N addresses, you can choose HDWallet, a hierarchical deterministic wallet (this only requires backing up a string of passwords) to avoid the trouble of backing up N private keys. And if you use Bitcoins from the same address on multiple devices (not recommended), be sure to wait until device A has fully confirmed the issuance of coins, and then synchronize the transaction with device B before you can issue coins to device B. Otherwise, if client A does not confirm that client B sends it again, it may cause a "double spend" and cause the second transaction to fail to be sent. What does "Warning! This transaction contains multiple payments" mean?

3. What company launches Kushen Cold Wallet? Is it reliable?

Kushen Cold Wallet is a product launched by Beijing Kushen Information Technology Co., Ltd. This company The company is mainly a professional company that provides secure storage solutions for blockchain digital currency. After using the Kushen cold wallet, I feel that the security factor is still very high, and I personally think it is relatively reliable.

4. Does CEO Exchange use cold wallet or hot wallet system for transactions?

They are a combination of the two. For larger amounts, they will recommend using cold wallets, and for smaller amounts, use cold wallets. It is recommended to use a hot wallet. Their hot and cold wallet system is the most complete one I have seen so far.

5. What is cold wallet storage technology?

Bitcoin cold storage technology is what CHIPS uses, but this platform is more advanced and uses brain wallet technology and decentralized storage. Compared with other platforms, security is of course the best

6. When was the Bitcoin cold wallet developed?

It has been around since the birth of Bitcoin. The earliest one can be Paper wallets (that is, written on paper) now have relatively complete electronic devices and do not touch the Internet, that is, cold wallets.

7. Bitcoin cold wallet technology, please know

It is a method of storing Bitcoin and protecting it from being stolen. CHIPS mainly accepts Bitcoin storage, and its Bitcoin cold storage technology is very good and safe.

8. How cold wallet and mnemonic hardware are made

Increase flexibility through trusted mnemonic words.
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.

9. What is a Bitcoin cold wallet

Refers to an offline wallet. Users usually use an offline Bitcoin wallet address to send and receive Bitcoins, and then use the wallet offline to send and receive Bitcoins privately. key to confirm the signature. Therefore, there is no way for hackers to steal the private key of the cold wallet. Since there is an additional link to confirm the signature offline, the use of Bitcoin cold wallets is not as convenient and quick as hot wallets.
