❶ The Importance of Blockchain Wallets

Now more and more people are beginning to participate in blockchain projects, and those who understand and participate in them believe that they will use them 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 blockchain assets 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 just a friendly format for the private key of the blockchain digital wallet.

Keystore: Mainly inIt is more common in Ethereum wallet apps (Bitcoin is similar to the Ethereum Keystore mechanism: BIP38), which is obtained by encrypting the private key through the wallet password. Unlike the mnemonic, it can generally 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.

❷ 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 certainThe value of , 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.

The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

❸ What does a wallet account in a blockchain exchange mean?

Digital wallets are tools for storing, managing, and using digital currencies, and they play an important role in the blockchain field. 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. Digital wallets store not money, but information about your Bitcoin, Ethereum and other digital currencies or digital assets.
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.

❹ Introduction to digital currency wallet development, blockchain digital wallet

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 in turn 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 given to those who are strong and able to afford funds.use.

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 security of account information.

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.

❺ What does blockchain mean and what are its main uses

In recent years, a hot word has appeared frequently on the Internet, that is "blockchain". This word gives people It’s a very noble and powerful feeling, but many people don’t know what blockchain means? And what are the main uses of blockchain? Let’s take a look at the relevant content that has been issued.

Blockchain Blockchain is actually equivalent to a disintermediated database, which is composed of a string of rubber data blocks. Each of its data blocks contains information about a Bitcoin network transaction, which is used to verify the validity of the information and generate the next block. In other words, blockchain is essentially a decentralized database.

In a narrow sense, blockchain is a chain data structure that combines data blocks in chronological order and is cryptographically guaranteed. Distributed ledger that cannot be tampered with or forged. Broadly speaking, blockchain is actually a distributed infrastructure and computing method that is used to ensure the security of data transmission and access.

In addition, the blockchain is composed of data layer, network layer, consensus layer, incentive layer, contractIt consists of six basic architectures: layer and application layer. Regarding its role, blockchain is mainly used to solve the trust and security issues of transactions. The above is the relevant content about the meaning and function of blockchain. I hope it can help friends in need.

❻ What can a blockchain wallet do

Blockchain wallet serves as a basic token management platform and even a user identity management tool. 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 the types of tokens and the improvement of the entire blockchain ecosystem, when wallets are no longer simply a tool for storing tokens, sending tokens, and participating in crowdfunding, they will also work with exchanges and crowdfunding projects. Focusing on transactions, gradually turning to tokens to realize their own application purposes.

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. As public chains mature, especially EOS, Ethereum, etc.With the gradual improvement of blockchain infrastructure, some game, financial, social, and pan-entertainment DApp applications have gradually developed.

❼ Main functions of blockchain wallet

Usually a wallet will include the following functions: Support the creation of wallet accounts by generating mnemonic words, Keystore files, and private keys. Supports exporting wallet account mnemonics, private keys, and Keystore files. Supports multiple wallet account management, account balance inquiry and transfer functions (QR code scanning support). Supports ERC20 tokens (balance display, transfer, token price display) and supports real-time display of currency prices in fiat currencies (USD and RMB). The historical transaction list displays the created account. The presentation form of the blockchain wallet is divided into address and account number, which we collectively refer to as the account number here. Accounts in different blockchains are different, and the degrees may also be different. The creation costs of different blockchain accounts are also different. For example, Ethereum and Bitcoin accounts are free, but EOS accounts require a certain fee to create. Since the creation of a blockchain account is a complex process, the existence of the wallet is to help users simplify these processes. Generally, during the process of creating an account, the wallet will guide the user to back up the private key or mnemonic phrase, and then conduct secondary verification to ensure that the user's backed up private key or mnemonic phrase is accurate. On blockchains that require payment to create an account, wallets will generally help users complete the payment process using traditional payment tools to reduce user difficulty. Digital asset management Digital assets mainly refer to various tokens on the blockchain. The existence of the wallet greatly facilitates users to manage the assets they own, including transfers, collections, viewing asset details, Transaction details, etc. The function is similar to that of a bank APP. You can see what assets you currently own, how much they are, and perform operations such as transferring your assets. It should be noted that assets between different blockchains cannot be transferred directly, that is, you cannot transfer BTC (Bitcoin) to an Ethereum account, nor can you transfer ETH (Ethereum) to a Bitcoin account. Digital Asset Transactions The digital asset transactions currently supported by the wallet mainly include the following three situations: currency-to-currency exchange, exchange transactions, and OTC transactions. Coin-to-coin exchange Through currency-to-coin exchange, assets on different blockchains can be exchanged. For example, you can directly exchange the BTC (Bitcoin) you own into EOS. General transactions can only be carried out in the form of a basic pair, and then the basic pair can be traded into the final destination currency. For example, if I want to change from A to C, I need to go through an intermediary.B is realized, A -> B, B -> C; and currency exchange simplifies this process, directly converting A into C to participate in ecological construction. Currently, some public chain designs encourage users in the ecosystem to actively participate in the public chain ecological construction. . The main forms include node voting, referendum, staking, etc. Node voting takes EOS as an example. EOS has a total of 21 super nodes. Users can vote for up to 30 nodes by staking their EOS. The purpose of voting is to allow users to choose those who can contribute to the development of the ecosystem. nodes, thereby promoting the stable development of the ecology. Referendum referendum refers to the blockchain ecosystem where participants can initiate proposals that they think are beneficial to the community, and the entire blockchain currency holders will vote. When the number of votes exceeds a certain standard, the proposal will automatically take effect. The referendum method is conducive to community users actively participating in blockchain governance. StakingStaking is the Chinese name for equity pledging. Currently, some public chains adopt the form of Staking to encourage currency holders to pledge Tokens and thereby generate stable nodes. For example, COSMOS staking can enable the pledger to obtain a certain annualized income (settled in pledge currency), similar to investing in a current financial management product in a bank. Experience Dapp application DApp is the abbreviation of Decentralized Application, translated as decentralized application, which refers to application development with blockchain as the underlying layer. Currently, DApps are mainly concentrated on Ethereum and blockchains such as EOS, TRON, and IOST. The relationship between DApp and the underlying platform is like the relationship between APP and iOS and Android systems. For example, EOS DApp cannot run on the underlying ETH, just as Android APP cannot run on the iOS system. You can experience the decentralized finance MakerDAO on ETH in your wallet, experience starting a competition in EOSRacing and win EOS rewards, or you can mine and manage money in the Liebi mining pool on IOST. Currently, some large-scale games exist in the form of third-party independent APPs. When experiencing DApps in the form of these APPs, you also need a wallet as a medium for login and transaction authorization. Asset appreciation wallets naturally have financial attributes. The current wallet has integrated a variety of financial tools and functions including mining pools, financial management, mining, project investment, etc., which can meet the needs of users for asset appreciation. Mining pool: Currently there are two main methods of mining: POW mining and POS mining. POW (Proof of Work) is computing power mining, which we are familiar with such as BTC (Bitcoin) and ETH (Ethereum) mining; POS (Proof of Stake) mining is imitating POW computing power mining, and currency holders can Mortgage tokens to validator nodes to receive reward dividends. At present, the mining pool of the wallet is basically based on POS mining. Some wallets also support the purchase of cloud computing power for BTC (Bitcoin) mining. Financial management: The financial management products in the wallet are very similar to traditional financial products. The only difference is thatThe only difference is the settlement method. An estimated rate of return is usually agreed upon. After the user uses the Token to purchase the financial product, it will be settled regularly according to the agreed settlement date, and can be withdrawn or renewed upon expiration. Mining: Mining is mainly based on DApp mining. The wallet integrates some DApp mining machine products. Using the mining machine can quickly and easily obtain the tokens you want to mine. Take the recently popular EIDOS as an example. EIDOS mining machines can help users realize automatic transfer mining. These mined Tokens can be sold on exchanges to obtain profits. Project investment: Take HOO Labs of Hufu Wallet as an example. You can use USDT to support the project and obtain the project's Token in a certain proportion based on the amount of USDT supported.

❽ What is imtoken wallet?

1. imtoken is a blockchain digital currency wallet. imtoken provides safe and convenient digital asset services to users in the blockchain field. imtoken is an ERC20-based wallet, and non-ERC20 currencies such as BTC cannot be stored. China prohibits the sale of digital currencies to Chinese citizens. All operations on imtoken are irreversible. Users must keep their private keys and carefully check the payee's address during transactions to avoid loss or mistaken payment. If the payment is lost or mistakenly transferred, the user cannot contact imtoken customer service to solve the problem.
imtoken supports multiple chains, and imtoken can help users manage accounts and assets on the blockchain. In the world of blockchain, wallets are tools used to help users manage assets and data on the chain.
2. imtoken creates a digital identity for users through a set of mnemonic phrases. Digital identity can manage multi-chain wallets at the same time, data encryption and decentralized storage. imtoken requires using an overseas Apple ID to log in to the App Store, search for and install it. After creating a digital identity, a multi-chain wallet is generated correspondingly. A set of mnemonic phrases copied when backing up the identity are imported into each public chain wallet of imtoken. Blockchain wallets are different from traditional wallets, and users need to choose carefully.
Extended Information
Since more than 95% of the tokens currently issued by projects are tokens issued using the Ethereum ERC20 standard, you need to use the wallet address of the Ethereum wallet to receive coins. Considering the current domestic actual situation and the popularity of existing wallet software, I recommend imToken.
1. Risk Assessment
Click to create a wallet. The first is a risk assessment page.
2. Back up the private key (mnemonic phrase and Keystore)
After completing the evaluation, you can create a new wallet. After setting the wallet name and wallet payment password and creating the wallet, the first step is to back up the mnemonic phrase and Keystore. This step is very important. I believe that after carefully completing the risk assessment above, you should understandMnemonic words and Keystore can help you restore your wallet, so you need to choose a suitable way to back it up, and it is best to backup it offline. For example, as mentioned in Da Mao’s article yesterday: It is best to save it offline - put it on a computer that is not connected to the Internet, and encrypt it. At the same time, don’t put all your eggs in the same basket. Da Mao’s own private key is usually backed up in 2-3 places.
3. Understand the wallet address
After the backup is completed, your wallet can be used. At the same time, you also get a new wallet address. You can use this wallet address to receive tokens from projects you participate in. If you participate through proxy investment, remember to click "Copy Payment Address" to send this wallet address to the proxy investor.

❾ 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 character. If you have the private key, you have 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.
