㈡ What does digital wallet mean?

What does digital wallet mean?

What does digital wallet mean? Life has become more and more networked, and assets have adapted to a more digital world. era. Everything is represented digitally, enabling its value to be instantly transferred and liquidated globally. So what does digital wallet mean? Let’s find out together.

What does digital wallet mean1

What is digital wallet

A digital wallet is equivalent to a bank account. Users can store, receive and send to others in a decentralized manner. Digital assets. Anyone with an internet connection can create their own unique wallet that registers its own private and public keys when interacting with the cryptographic network for such assets. The private key is the unique identity or password that gives the owner access to such a wallet. A public key is the address used by the owner to send or receive digital assets. Because every transaction is recorded in a cryptographically secure distributed ledger, anyone on the network can audit it while retaining the anonymous component of the sender. This enhances a more transparent, trackable and secure online experience for users, allowing them to look for more decentralized options in banking.

Creating a digital wallet is very easy. This is why people believe that blockchain applications can solve the problem of unbanked people because more people in the world have access to the Internet rather than bank accounts. The new accounting system provided by blockchain simplifies the process of transferring value without the need for intermediaries.

Cryptocurrency Asset Wallet

Cryptocurrency uses blockchain technology for transactions. Each cryptocurrency asset such as Bitcoin, NEM, Ethereum and Komodo has its own native wallet that you can download from their official website. You can also find wallets that support multiple crypto assets. Remember, when you transfer cryptocurrency to another cryptocurrency, you are actually transferring the value that represents the currency. An Ethereum transaction could represent a real estate purchase in Dubai, a ship arriving from the port of Cartagena, or even a trading card. This is why we use “cryptocurrency assets” as the terminology discussed here, rather than the term “cryptocurrency.”

There are two types of wallets: hot wallets and cold wallets, which are stored securely on websites, applications.

Hot Wallet

Create your own cryptocurrency asset walletThe easiest and most convenient way is to use a hot wallet. It can be an app on your phone, computer or tablet, which are always connected to the web. When you store your crypto assets on an exchange like Binance, Huobi, or Coinbase, you store them in a hot wallet, they generate your private keys, and you don't necessarily have access to them.

Be careful when storing crypto assets on an exchange because if you are not the owner of the private keys, you do not own the crypto assets.

Cold wallet

The most secure wallet - stores crypto assets offline, making them impossible to hack. Users can use their private keys to enter the wallet interface and connect to the network to view their balances, and can also exchange with other supported cryptocurrency assets. You can also memorize a seed phrase password consisting of 10-12 words and use it as the entry point to your digital wallet.

What does digital wallet mean 2

1. The difference between digital wallet and ordinary wallet

1) Ordinary wallets put paper banknotes directly. If they are lost, the money inside will be taken away by others. .

2) Digital currency wallets do not actually store assets directly. Use your private key, or the core key that controls your digital assets, to view or use your digital assets.

2. Differences from exchange accounts

There is a difference between placing assets in a digital wallet and placing them in an exchange. Strictly speaking, the assets stored in the exchange account are not yours to control. The digital currency wallet is the tool for you to truly control your own assets in the blockchain world. And when you store your assets in an exchange account, the exchange here generally refers to our most commonly used centralized exchange. You deposit your coins into the exchange's large wallet, and the exchange will help you manage it.

In other words, from a security perspective, the assets stored in the wallet are completely at your disposal; but in a centralized exchange, if the exchange is stolen or the account is hacked, If so, you may not be able to get your assets back.

3. Functions of digital wallets

What are the main functions of a typical digital asset wallet?

The first is to save the key to control your blockchain assets, which we call the private key.

Secondly, it can check your assets. Based on your private key, public key and address, you can check how many Bitcoins, Ethereums, etc. you have on the blockchain.

Third, when transferring money from the wallet, the signature required during the transfer process and the function of broadcasting to the blockchain network will be used.

㈢ A brief discussion on how to choose a blockchain wallet that suits you

This is what I think about blockchain wallets
The current digital currency wallet isFor example, there are many wallets that we usually come into contact with, but the materials are different.
If you have a lot of currency, it is recommended to store more distributed ones. As for choosing, choose a large one that is reliable and convenient for transactions.

㈣ [Blockchain] What is a blockchain wallet?

When it comes to blockchain wallets, we have to talk about Bitcoin core (Bitcoin core) and other blockchain wallets Most of them are modeled after Bitcoin wallets, which are our tools for managing Bitcoins.

Our Bitcoin information is stored in the Bitcoin wallet, including Bitcoin address (similar to your bank card account number) and private key (similar to your bank card password). The Bitcoin wallet can Store multiple Bitcoin addresses and the independent private keys corresponding to each Bitcoin address.

The core function of a Bitcoin wallet is to protect your private key. If the wallet is lost, you may lose your Bitcoins forever.

Blockchain wallets come in many forms.

According to whether the user has the private key, wallets can be divided into: on-chain wallet (onchain wallet) and escrow wallet (offchain wallet). There are two differences between them:

Regarding on-chain wallets (onchain wallets), we can divide them into cold wallets and hot wallets according to whether the private key storage is connected to the Internet; we also call cold wallets and hot wallets They are offline wallet and online wallet.

Generally speaking, hardware wallets are cold wallets (it is generally recommended to use cold wallets to store large amounts of digital currency that are intended to be held for a long time). In addition to this kind of professional equipment, we can also use offline computers, Mobile phones, paper wallets, brain wallets, etc. are used as cold wallets to store our digital assets.

The biggest advantage of a cold wallet is its security, because it does not touch the Internet, which can greatly reduce the possibility of hacker attacks; the only thing you need to worry about is not to lose your cold wallet.

Corresponding to the cold wallet is the hot wallet. Hot wallets need to be connected to the Internet; hot wallets can be divided into desktop wallets, mobile wallets and web wallets.

Hot wallets are often in the form of online wallets, so when using hot wallets it is best to set different passwords on different platforms and enable secondary authentication to ensure the security of your assets.

According to the maintenance method of blockchain data and the degree of decentralization of the wallet, wallets can be divided into full node wallets, light node wallets, and centralized wallets.

Most full-node wallets are desktop wallets, representatives of which include Bitcoin-Core core wallet, Geth, Parity, etc. Such wallets need to synchronize all blockchain data and occupy a large amount of memory. , but can achieve complete decentralization.

Most mobile wallets and web wallets are light node wallets. Light wallets rely on other full nodes in the blockchain network and only synchronize transaction data related to themselves, which can basically achieve decentralization.

The centralized wallet does not rely on the blockchain network. All data is obtained from its own centralized server; however, the transaction efficiency is very high and can be credited in real time. The account you registered in the trading platform It is a centralized wallet.

Remember that in the world of blockchain, whoever holds the private key is the real owner of digital assets.

㈤ What is the meaning of wallet account in blockchain exchange

Digital wallet is a tool for storing, managing and using digital currencies, and it plays a decisive role in the field of blockchain. It is a software program or hardware device that stores cryptocurrency. In form, it is similar to an online bank account, which also has a customer ID, account number, and password. The password of the digital wallet is the "private key". Only through it can the wallet be opened and operated. Digital wallets have "receipt" and "transfer" functions, just like depositing and withdrawing money with a bank card. You need a card number and password to make normal deposits and safe withdrawals. A digital wallet does not store money, but your Bitcoin, Ethereum and other digital currencies or digital asset information.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.

㈥ What can a blockchain wallet do

Blockchain wallet serves as a basic token management platform and even an identity management tool for users. For example, when a user wants to play a CryptoKitties game, he or she can open the wallet, enter the DApp, select it and use it, or download the DApp application locally through the wallet and use it directly.
With the increase in token types and the improvement of the entire blockchain ecosystem,When the wallet is no longer simply a tool for storing tokens, sending tokens, and participating in crowdfunding, it will gradually shift from dealing with exchanges and crowdfunding projects to realizing its own application using tokens.

1. The wallet serves as the entrance value for payment

The payment method is the same as the existing mobile payment, and the payment can be completed by scanning the QR code to confirm. As off-chain payments such as Lightning Network and Raiden Network mature, or technologies such as sharding and sub-chains mature, once digital token payment becomes one of the mainstream payment methods in the future, wallets such as Cobo will have great potential as entrances. space.

2. The value of wallet as an asset management platform

Now there is an opportunity for user-side wallets to rise. First, there are tens of millions of users, all of whom are valuable users. Second, with the development of the entire ecosystem, derivatives have also begun to develop and there is demand. For example, when users have some tokens, some of them are long-term value investors. For example, some users will hold Bitcoin, Ethereum or EOS for a long time. But if they just store them, they will not make the best use of the assets. Somewhat wasteful. At present, there are more and more public chains, more and more protocols and applications, and more and more tokens. Centralized exchanges, decentralized exchanges, quantitative trading, etc. are all developing. There are many financial and asset management solutions here. Chance.
3. The value of wallet as the entry point for transactions

Since wallets have accumulated a lot of users’ digital assets, when users need to conduct transactions, the more troublesome point is that they need to transfer to the exchange. If compared There is congestion, it takes a long time, and it is easy to delay things. On the exchange, if the trading depth is not enough or the price is not suitable, it is often difficult to complete the transaction. If it is a large-scale transaction request, instant shipment or purchase will affect price fluctuations. If the wallet is combined with some decentralized or centralized exchanges, such as users inputting their ideal prices, transactions can be matched as quickly as possible. For users, fast transactions can be achieved in the wallet, which is also a good demand scenario.
4. The value of wallet as an entrance to the DApp market

For wallets, the DApp market entrance is definitely the most imaginative prospect. With the maturity of public chains, especially the gradual improvement of blockchain infrastructure such as EOS and Ethereum, some game, financial, social, and pan-entertainment DApp applications have gradually developed.

㈦ 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.

㈧ [Blockchain Course] 3.1—The Concept and Characteristics of Digital Wallet

1. The Concept of Wallet

The traditional wallet in life is equivalent to a A container can be used to store cash, but for digital currency wallets, it is not used to store digital currency, but a management container used to store and manage (including private keys and public keys). The digital wallet has an address (similar to (based on your bank card account number), private key (similar to your bank card password).

Private key: The user uses the private key to sign the transaction, thereby proving that he has the right to output the transaction. The transaction information is not stored in the wallet, but in the blockchain.

Public key: used to generate addresses and store transactions. Information is generated by the private key through an asymmetric encryption algorithm.

Wallet address: It is a 42-digit hexadecimal hash value string starting with a double letter (representing the currency). The address of ETH is 42 bits starting with 0x 16Base hash value string. For example: If a wallet is compared to a bank card, then the wallet address is the bank card number.

The relationship between the three is simply: the private key generates the public key, and the public key generates the address. In short, the address is your account, bank card number, and the private key is your account password. So if someone steals your private key, they will definitely have ownership of your account.

2. Characteristics of wallet

Analogy to a bank card, the private key is like our bank card password + bank card account number, and the digital currency address generated based on the public key is like Our bank card account number is used as the transfer address for transactions. Digital currency is stored in the trading market. The bank card of the wallet keeps our address and password information, giving us control over the digital currency corresponding to the address.

3. The value of wallet to blockchain

Encrypted digital currency is a digital currency based on blockchain technology. Digital currency wallets are specially used to manage these Application of assets. The wallet application creates one or more wallet addresses based on cryptographic principles, and each wallet address corresponds to a key pair: a private key and a public key.

The public key is generated by performing certain mathematical operations based on the private key, and corresponds to the private key one-to-one. The public key is mainly used for external transactions. Each transaction must use the private key to sign the transaction record to prove control over the assets in the relevant wallet address.

The private key is the only certificate that can prove control over digital assets. For digital asset wallets, the private key is the most important. The way the private key is generated and stored determines whether the asset is safe or not.

So the purpose of the wallet is to store the private key. As long as you have the private key, it means you have the corresponding token.

However, the current digital currency market has problems such as inconvenient digital management, high transaction and exchange thresholds, insufficient blockchain performance and unreasonable design, high blockchain development costs, difficulty in connecting to reality, and lack of application scenarios. And other issues. To put it simply, tokens developed based on different public chains require their own wallets, so our mobile phones are filled with apps for multiple wallets.

4. Several key words of digital wallet:

1. Wallet name:

The wallet name of the digital currency wallet is when you create the wallet Account name or nickname, each wallet address corresponds to an account name, because usually digital wallets can create multiple wallet addresses. In order to facilitate identification and management, it is necessary to set a name for each wallet address.

2. Password:

When you create a digital currency wallet account, you need to set oneA password, you need to use this password confirmation when you transfer and pay; you also need password confirmation when you back up and export the wallet's private key or keystore; in addition, if you use keystore to import the wallet, you also need password confirmation, and use the private key Passwords can be reset during import.

3. Mnemonic phrase:

When you create a wallet, you will be asked to record a string of mnemonic phrases, usually consisting of multiple (12, 15, 18 , 21 digits) composed of irregular English words without any rules, equivalent to the password of your digital wallet + payment password. You will be prompted to save the mnemonic phrase when creating a wallet. Please be sure to save it. It is recommended to record it in a separate notebook with a pen and keep your notebook.

4. Keystore:

The keystore is a file (json) where the wallet stores the private key. The wallet password is required when using this file. When you choose to export or import keystore, you need to enter a password. This password is the password you originally set for this wallet. This is different from using a private key or mnemonic phrase to import a wallet. Using a private key or mnemonic phrase to import a wallet does not require If you know the original password, you can reset it directly.

㈨ What is a blockchain wallet

The electronic wallet is part of the basic equipment of blockchain banking. To simplify, we will explain this technology using Bitcoin, although it applies to all other blockchain-based cryptocurrencies as well.
Blockchain wallets are software programs that store cryptocurrency. Account owners have a private key (secret number) leading to their wallet. This key is the only way to access a Bitcoin address and therefore the only way to receive or send credits. There are several providers that offer private keys, but all are compatible with each other.
Wallets come in many forms, which we will introduce in detail later. Currently, the top five types of wallets exist in the form of desktop electronic currency wallets, mobile electronic wallets, Internet electronic wallets, hardware wallets and paper money wallets.
In the wallet, users retain their Bitcoin assets. In principle, Bitcoin is just "ordinary" money in an ordinary wallet. So, users won’t put all their money into one wallet and not feel it is very secure. In this case, the user needs to use a backup copy and a secure password. Additionally, users can treat the wallet as a passbook (paper wallet). This has no internet access and therefore, it is not more vulnerable to cyber hackers.
Bitcoin has a certain value, which comes from a value we assign to it. So this is similar to "normal" money. The value of Bitcoin also depends heavily on exchange rates, but this varies widely, so Bitcoin's value can sometimes fluctuate more dramatically than a normal currency. Let’s take a look at the Bitcoin chart this year and we’ll see a huge jump in value. Some parts are like a roller coaster.

㈩ Introduction to the development of digital currency wallets, blockchain digital wallets

The blockchain digital wallet system can conduct unified management of multiple mainstream digital currencies such as Bitcoin and Ethereum. And storage, that is to say, all currencies are installed in one wallet for management, which greatly reduces the threshold for using digital currencies and the management burden, and is also very flexible and convenient to use.

Blockchain digital currency wallet functions:

1. Financial management: When developing a blockchain wallet APP, you can add mortgage loan functions or other functions. For example, bringing money to earn interest or other financial management functions.

2. Recommendation rewards: This is the reward mechanism of the wallet APP. For example, if you invite new users through links or other channels, you will also receive certain rewards. This mechanism can also This will also attract more users.

4. Trading system: If you want to trade when you see the market, the trading module in the general wallet can have Lianzhong's approach. For this purpose, a trading module can be directly developed and then used by those who are strong and able to afford funds.

5. Market information: For users, market conditions are very important. They can obtain new information at any time in order to make timely adjustments, so this function is equally important.

Advantages of blockchain wallet App development:

1. Distributed storage

Blockchain wallets that use distributed storage eliminate The influence of centralization is to store data in different nodes in a distributed manner, ensuring the security of users' wallets and data, and removing the central management mechanism. If someone wants to steal the user's wallet account information, they need to first find the node where the user stores the information, and then attack different data storage nodes at the same time, instead of just attacking one central point as before, which increases the number of hackers. The difficulty of stealing user information ensures the security of user information.

2. Encryption algorithm

Every data storage node in education has the application of encryption algorithm, and a user’s data is not only stored in several nodes, but also Among the unclear nodes. It may be hundreds, thousands, tens of thousands, etc. Each node has the application of encryption algorithm, which further improves the account information.safety.

3. Traceability

Traceability is the most practical aspect of a blockchain wallet. When a user transfers a wrong account, the transferred money can be recovered through the application of technology. Chase back. Since transfer is also a kind of data transmission information, we only need to trace the source of the data, submit a management application, and retrieve the money data.
