区块链的冷钱包和热钱包的区别,区块链的冷钱包和热钱包哪个好

1. How many types of blockchain wallets are there

How many types of blockchain wallets are there? It can be roughly divided into two categories, hot wallets (online wallets) and cold wallets (offline wallets)

1. Hot wallets
Hot wallets are also called online wallets, including light wallets and heavy wallets. Wallet (full node wallet), which needs to be kept online, can directly perform transaction operations.
1. Light wallet:
Does not store the complete blockchain, only saves data related to itself. It is small in size and can be run on mobile phones, computers, web pages, etc.
Advantages and disadvantages: Does not occupy memory, supports multiple digital assets, good user experience, quick to get started with novices, but transaction verification is slightly slow
Common digital currency light wallets include: cobo, geek wallet, kcash, etc.
2. Heavy wallet (full node wallet)
Maintains all blockchain data, is completely decentralized, and synchronizes all data. It has better privacy and can verify the validity of transaction data locally.
Advantages and disadvantages: It has better privacy and faster verification of information, but it requires data synchronization before each use, takes up a lot of hard drive space, and does not support multiple digital currency transactions.
2. Cold wallet
A cold wallet is a wallet that is not connected to the Internet, also called an offline wallet; such as professional hardware equipment, or writing the private key (mnemonic phrase) on paper.
1. Hardware Wallet
Hardware wallet uses professional hardware to store digital currency, and stores the private key of digital assets in a separate chip, which is isolated from the Internet and is plug-and-play.
2. Paper wallet
Write the private key on paper and store it, then delete it
Advantages and disadvantages of cold wallet:
Relatively safe, but creating a wallet and making transactions are very troublesome. It is difficult for novices to operate, and wallet prices are relatively expensive, generally ranging from a few thousand to tens of thousands of yuan. If you don’t have a large amount of digital assets, you don’t need to consider it.

2. Can multiple hot wallets be registered?

Yes. A hot wallet is a hot wallet when connected to the Internet. It is also an online wallet. It is always connected to the Internet and can quickly provide access services to currency holders. It is more convenient and faster. One person can open 6 digital wallets. , you can register multiple ones. Hot wallet corresponds to the cold wallet, also known as online wallet or Internet wallet. It is one of the types of blockchain wallets, that is, the wallet where the network can access the user's private key. Because of its networking characteristics, hot wallets allow outsiders to access users through the Internet. The private key is therefore less secure than a cold wallet, but more convenient than a cold wallet. In addition, whether you use a cold wallet or a hot wallet, the private key is the key.

3. Which blockchain wallet is easier to use

With the development of the blockchain industry to this day, the underlying layer and technology have become very mature. So the blockchain wallets of each company will not be very different.

How do you think it is easier to use? In fact, it mainly depends on safety.compatibility, supported currencies and experience optimization. Essentially, blockchain wallets are divided into two categories: hot wallets and cold wallets (hardware wallets).

1. Hot wallets can be equivalent to software wallets to a certain extent.

The advantage is that it is simple to operate and easy to manage, and is more suitable for entry-level users.

But the disadvantages are also obvious. Every transaction requires online verification, and data security cannot be guaranteed.

The relatively well-known hot wallets on the market such as imToken, Math Wallet, etc.

2. Cold wallets generally refer to hardware wallets.

The private key of the cold wallet will never touch the Internet, and the private key will never enter the network. A hardware wallet is a specialized electronic device used to store encrypted assets. Its function is to store private keys in an internal chip. The private keys never leave the device, so they are safe. Therefore, general hardware wallets are cold wallets.

Advantages: The private key is generated through a mnemonic phrase and is permanently retained inside the hardware wallet. It will not be leaked out, so security is high.

Disadvantages: It’s not very convenient to use, it doesn’t matter if you receive it or not, you just need to provide an address for the removal. To send, you need to connect the device to your computer or mobile phone. So it is not as convenient to use as a hot wallet.

The first consideration when choosing to use a hardware wallet is security, so generally if you want to truly protect your assets, you must prepare a hardware wallet.

Currently, there is no hardware wallet with particularly complete currency coverage on the market, but there is a blockchain wallet called TJ Wallet, which is the first safe and reliable software and hardware ecological wallet supported by Filecoin in China. Triple hardware encryption supports mainstream currencies such as BTC, ETH, Filecoin, and supports the expansion of all currencies. It takes into account both convenience and security. It is a good blockchain wallet. The questioner can pay attention~

4. What are blockchain digital asset cold wallets and hot money

Bitcoin wallets come in many forms, such as PC or mobile wallet clients, online Web wallets, or even small notebooks (paper wallets) or brains (brain wallets) that record Bitcoin private keys. You can choose a wallet that suits you based on your needs.

Bitcoin wallets can be divided into cold wallets and hot wallets according to the storage method of private keys.

01. A cold wallet refers to a wallet where your private key cannot be accessed by the network.

Cold wallets often rely on "cold" devices to ensure the security of Bitcoin private keys, such as computers, mobile phones, and small notebooks with private key addresses written on them that are not connected to the Internet. Cold wallets avoid the risk of private keys being stolen by hackers, but may face physical security risks, such as computer loss and damage.

02. Hot wallet refers to a wallet that can access your private key via the Internet.

Hot wallets are often in the form of online wallets. When using hot wallets, it is best to set different passwords on different platforms and enable them twice.Certification to ensure the safety of your assets.

A wallet is actually a "management tool for private keys, addresses and blockchain data."

5. The importance of blockchain wallet

Now more and more people are beginning to participate in blockchain projects, and those who understand and participate in it believe that they will use the blockchain wallet. Blockchain wallet, the "wallet" here refers to a virtual tool used to store and use virtual currency.

Wallets are mainly divided into cold wallets and hot wallets, which include private keys, public keys and auxiliary words. Next, I will explain their differences and functions in detail.

Cold wallet: A cold wallet refers to a wallet that is not connected to the Internet and stores digital currency offline. Users generate digital currency addresses and private keys on an offline wallet and then save them. 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, which can effectively prevent hackers from stealing.

Hot wallet: Hot wallet refers to a wallet that needs to be connected to the Internet. It is more convenient to use, but now the network is more complex, there are many phishing websites, and there are risks, so it is difficult to use a wallet or exchange. It is best to set different passwords and enable secondary authentication to ensure the security of your assets.

In summary, cold wallets are more secure than hot wallets.

Private key: The private key is a string of data generated by a random algorithm. It can calculate the public key through an asymmetric encryption algorithm, and the public key can then calculate the currency address. The private key is very important, as the password is hidden from all but the owner of the address. Blockchain assets are actually on the blockchain. The owner actually only owns the private key and has absolute control over the assets in the blockchain through the private key. Therefore, the core issue of blockchain asset security lies in the storage of the private key. The owner must keep it safe. Compared with the traditional form of username and password, the biggest advantage of using public key and private key transactions is to improve the security and integrity of data transmission. Because of the corresponding relationship between the two, users basically do not have to worry about the data transmission process. The possibility of being intercepted or modified by hackers. At the same time, because the private key encryption must be decrypted by the public key it generates, the sender does not have to worry about the data being forged by others.

Public key: The public key appears in pairs with the private key. Together with the private key, they form a key pair and are stored in the wallet. The public key is generated from the private key, but the private key cannot be derived from the public key. The public key can obtain the wallet address through a series of algorithm operations, so it can be used as a certificate of ownership of this wallet address.

Mnemonic phrase: The mnemonic phrase uses a fixed algorithm to convert the private key into more than ten common English words. The mnemonic phrase and the private key are interoperable and can be converted into each other. It is justAs a friendly format for blockchain digital wallet private keys.

Keystore: Mainly common in Ethereum wallet apps (Bitcoin is similar to the Ethereum Keystore mechanism: BIP38). It is obtained by encrypting the private key through the wallet password, and the mnemonic phrase Different, generally it can be saved as text or JSON format. In other words, Keystore needs to be decrypted with the wallet password before it is equivalent to the private key. Therefore, Keystore needs to be used with the wallet password to import the wallet. When a hacker steals the Keystore, without a password, it is possible to unlock the Keystore by brute force cracking the Keystore password. Therefore, it is recommended that users set a slightly more complicated password, such as adding special characters, at least 8 characters, and make it safe. storage.

In summary: The function of the wallet is to protect our private key. The private key is the full authority to control the assets. Only those who have the private key can use the virtual currency in this account. When using the wallet, remember not to disclose your wallet's private key, mnemonic phrase, Keystore and other information to others. This information is important information that can directly steal your digital assets.

Things to note when using the wallet:

1. Make a backup copy of the private key and mnemonic phrase. It is best to write a handwritten copy on your mobile phone and save it.

2. Do not click on unknown websites easily.

3. Do not take screenshots or take photos to save.

In short, the most important thing is to keep your private key.

6. The difference between cold wallets and hot wallets

1. The cold wallet does not contact the Internet, uses a new technical model to ensure that the cold end hardware never contacts the Internet, and uses multiple encryption protection systems Ensure 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 are stored in a decentralized manner, with each address storing 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 operating 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.
