How about blockchain local wallet

1. Before developing wallet, we need to have the following preparatory knowledge
first, what is a wallet and its related categories? Xrv522 can develop blockchain wallets
from the perspective of developers, this article explains to readers how to interact with wallet and how to develop a wallet
How do we understand wallets? In short, it is an entrance to connect the blockchain. At present, mature public chains such as bitcoin and Ethereum have many wallets to choose from. Generally, the wallet needs full access to your user assets, that is, it will ask you to enter the private key. The evil cost of wallet is very low, which is one of the reasons why I suggest to choose open source wallet.

virtual currency wallets and local wallets are wallets specially used to store virtual currency

difference: local wallets are installed on their own computers or mobile phones, while online wallets encrypt the private key and put it on the server

personal computers may be implanted with Trojans; The wallet server also has the risk of being attacked by hackers, and the encrypted private key is cracked. Server security is better than personal computers, but it is easier to attract hackers' attention

< H2 > extended data:

virtual currency Wallet:

there are three main types: Online wallet, client wallet (mobile client, computer client) and hard wallet

1. Online Wallet: it refers to the operation of virtual currency relative to wallet by users in the form of network; The main form is website, which users can visit through computer and mobile phone

2. Client Wallet: it is an installation software, which needs to be downloaded to the computer or mobile phone, and can only be used after installation; This is the type of mobile app wallet that I just mentioned

3. Hard Wallet: it is similar to the wallet in the form of U disk, which is a real type of wallet

local Wallet:

the English name of local wallet is local wallet. Local wallet is to store private key and transaction data in local terminal, such as computer, mobile phone or other local devices; It refers to the storage location of the key, and its concept is independent of online wallet and offline wallet

the English name of local wallet is local wallet. It is one of the terms related to bitcoin wallet in blockchain. Local wallet is to store private key and transaction data in local terminal, such as computer, mobile phone or other local devices; Local wallet refers to the storage location of key, which is independent of online wallet and offline wallet

the local wallet is installed on your own computer or mobile phone, while the online wallet is encrypted and put on the server. Personal computers may be implanted with Trojans. Hackers may steal your wallet files and record your wallet password; The wallet server may also be attacked by hackers, and the encrypted private key may be cracked. Server security protection is better than personal computers, but it is also easier to attract hackers' attention. In terms of security, I think these two types of wallets are similar

to enhance the security of local wallet and online wallet, it's better to set a more complex password, and don't forget it. Both local wallet and online wallet are easy to use and easy to use. Because online wallet is not limited by clients, it is easier to use than local wallet. Bitcoin core, Bitai wallet and bitpai wallet all belong to this category

3. The essence of a blockchain wallet is a private key, which is a random hash string. If you have the private key, you have the right to use the wallet. According to the storage method of the private key, it can be divided into cold wallet and hot wallet
cold wallet refers to the wallet where the network can't access your private key. Generally, it will take a notebook to record it. Although it avoids the risk of being stolen by hackers, it may also be lost
a hot wallet is a wallet that can access your private key on the Internet. Hot wallets are often in the form of online wallets, which are not easy to lose, but also have risks.

4. Blockchain wallet is a tool to save the private key of blockchain digital currency. Every digital currency has a wallet. The types of blockchain wallet are as follows:
1. General wallet
can support different blockchain tokens. For example, anmao wallet supports BTC, BCH, LTC, ETH, etc, dash and erc-20 series
2. Main Chain Wallet
in order to achieve their own goals, each coin must establish its own main chain, so that it can carry out business. After the main chain goes online, it needs to use the project's own wallet. Just like the green apple wallet of GAC coin, it is a wallet dedicated to GAC trading and transaction clearing
3. Exchange wallet
there are also wallets in the exchange. If the player's currency is recharged into the exchange, the corresponding currency will enter the exchange wallet. The exchange wallet is almost the same as the ordinary wallet. You can fill in the corresponding wallet address when transferring and withdrawing cash, and the corresponding wallet address will be generated for different currencies of each exchange
4. Hardware wallet
generally speaking, the wallet is software wallet, which is a PC program or app. As the name suggests, a hardware controlled wallet can be connected to the network when it is used, and can be stored off the network at other times, so as to avoid exposing the wallet to the network space.

5. The blockchain wallet is used to store the token virtual digital assets on the blockchain
is similar to Alipay or bank card.

6. Hello
ordinary investors and users can use wallets to achieve what needs
What do you think of when you think of wallet
1. Hot wallet, cold wallet, observation wallet—— Realize the most basic function of a wallet: storage
2. DAPP entry of different public chains—— The entrances of the coin holders to the dapps of the public chains
3. Flash cash, direct trading in the exchange and cash out—— The transaction and Realization of digital assets
4. Pay attention to the market information to understand the currency price
Yes, some blockchain wallets have been implemented. It makes people feel like "a small purse, a big world". The actions that users want to complete in the blockchain world can be basically solved in their wallets
take the tokenpocket wallet that I often use as an example< How to understand hot wallet, cold wallet and observation wallet
Hot Wallet: Online wallet, online wallet. It is convenient to withdraw money. You can also check the wallet assets, balance and transaction records at any time
cold Wallet: it's an offline wallet. Since it's offline and not connected to the Internet, how can I realize it when I need to transfer money or withdraw money? Just watch your wallet
observe Wallet: a wallet that observes the assets of a cold wallet and assists in withdrawing the cold wallet's assets< Second, TP SDK integrates Tron
the latest version of TP SDK now supports Tron, that is to say, when the independent DAPP on the wave field public chain is connected to the tokenpocket SDK, it can realize the operation of Tron authorization login, data signature, token transfer, transaction signature, etc
in this way, the development of Tron independent DAPP is greatly accelerated
Third, asset collection function
we usually have such a phenomenon: everyone has multiple accounts, and these accounts have the same token. If you want to collect the same asset on these different accounts, you need the asset collection function
there is a problem: if the passwords of all your accounts are the same, you can authorize them once. If the passwords are different, you need to authorize each time
note: please do not close or exit the collection interface before the completion of the collection operation to prevent errors
Fourth, experience the colorful DAPP on each public chain
in the TP interface, select the Tron category to enter the Tron DAPP page. Play all kinds of DAPP, or enter other public chains, such as EOS, Jingtong, etc
there are more functions in the wallet, waiting for further exploration.

7. In order to understand the blockchain wallet, we must first understand several core concepts
1. Wallet address: similar to the bank card number, a person can have multiple bank cards. Similarly, he can also have multiple wallet addresses. A wallet address can only correspond to one private key
2. Wallet ID: customer ID (name) similar to bank card
3. Public key and private key: the holder of the private key is the holder of the currency in the bank card. The private key can calculate the public key, the public key can generate the wallet address through a series of digital signatures, and the data encrypted by the private key can be decrypted by the public key, or vice versa
I know this area quite well, and I have some ideas to develop a blockchain wallet. After all, it is a high-tech wallet. Before I learned about a development company called Xuanling technology on the Internet, and also consulted the people over there. I felt that it was quite professional. I hope I can help you~

8. It can be said that it is very unsafe. The technology related to blockchain wallet has lost its original technical meaning in China. Now it has been reced to a means of money. Therefore, we must be very vigilant in this aspect. Anyway, I personally don't believe it.
