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

1. The Concept of Wallet

The traditional wallet in life is quite It is a container that 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). There are addresses in the digital wallet (similar to 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 a 42-digit hexadecimal hash value string starting with 0x. 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 it's privateKey means that 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 a password. When you transfer and pay, you need to use this password to confirm; Password confirmation is also required when backing up and exporting the private key or keystore; in addition, if you use keystore to import the wallet, you also need password confirmation, and you can reset the password when importing using the private key.

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.

II Under what circumstances can a blockchain digital wallet never be recovered?

Blockchain digital wallet is a necessary tool, and if you are not careful, digital currency may be lost. Finally, remember:
1. The blockchain digital wallet contains keys, so you must keep them safe.
2. Remember the private key and mnemonic phrase offline, and do not tell them to third parties, otherwise it will be equivalent to putting your assets in front of others.
3. Try to use wallets with higher security that have been verified over time and have more users.
Otherwise moneyOnce a package asset is lost, it can never be found again.

Ⅲ What is the meaning of wallet account in blockchain exchange

Digital wallet is a tool for storing, managing and using digital currencies, and 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.

IV Introduction to digital currency wallet development, blockchain digital wallet

The blockchain digital wallet system can uniformly manage and store a variety of mainstream digital currencies such as Bitcoin and Ethereum. That is to say, all currencies are managed in one wallet, which greatly reduces the cost of digital currencies. The usage threshold and management burden are low, and it 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 remove the influence of centralization and store data Decentralized storage in different nodes ensures the security of user wallets and data, and removes 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.

Ⅷ Is Star Wallet a pyramid scheme?

It is a pyramid scheme.

Interstellar Wallet, whose real name is S-Block Interstellar Wallet, is a one-stop digital asset multi-functional management platform that aims to use blockchain technology to help users exchange value more conveniently. Previously, it was renamed to Shengwei, VV Wallet, etc. for various reasons.

1. SBlock Interstellar Wallet investors mainly obtain high returns through "moving bricks" arbitrage and recommending others to join. First, you need to download and register as a user of SBlock interstellar wallet through the recommendation code provided by the recommender, then deposit a few US dollars of virtual coins, start the S-KEY master node income, you can become a "fan" of the platform, and start enjoying 0.2 every day With a static income of 0.5%, the monthly income can be as high as 15%.

2. For some people who are not satisfied with static income, they also play new things with dynamic income to attract people's income. This is a typical pyramid scheme model. Involve friends around you into the trap. The more people you recruit, the higher the team's income will be. Once they achieve what they want, there are many examples of people directly shutting down the network and running away.

3. The team will help you brainwash first, so that your friends will be convinced by you. There are many people who are greedy and want to reinvest, which is exactly what you want. Once invested, it is a lesson of blood and tears. Everyone should keep their eyes open and be wary of this kind of project that is a sure profit but not a loss, which is harmful to others.

(8) Blockchain International sblock digital wallet extended reading

MLM It refers to the behavior of organizers developing people and illegally obtaining wealth by developing people or requiring people to be developed to obtain membership qualifications on the condition of paying a certain fee.

MLM behavior has the following three characteristics:

(1). The first payment or a disguised payment of a high entry fee, that is, the accrual can only be obtained after paying the entry fee or purchasing goods at a high price.Compensation and development of downline “qualifications”.

(2) Direct or indirect development of offline, that is, attracting people to join and forming levels in a certain order.

(3) The upline will accrue remuneration from the sales performance of the downline developed directly or indirectly, or accrue remuneration or rebate based on the number of personnel developed directly or indirectly. The essence of pyramid schemes is to deceive others into purchasing goods of no value through fictitious facts and high profits.
