How is the wallet stored in the blockchain

1. There are many kinds of wallets in the market, which can be divided into desktop wallets, mobile wallets, online wallets, hardware wallets and paper wallets according to the platform; According to whether it is connected to the network, it can be divided into cold wallet and hot wallet; According to the degree of autonomy and the way of interaction with the network, it can be divided into full node wallet, SPV light wallet and third-party wallet
for blockchain wallets, you can see the evaluation of wallets in password finance if you go to the tutorial.

2. Centralized wallet, also known as off Chain Wallet, completely depends on the company and server running the wallet. bitcoin stored in the exchange is stored in the centralized wallet (off Chain Wallet). The private key is not owned by the user, but in the wallet project side of the centralized server hosting chain, the fund is usually entrusted to the server
private keys and assets are transferred to the wallet for centralized management. Users don't need to worry about the loss of the private key of this kind of wallet procts, resulting in the loss of funds; However, the capital risk will be more concentrated in the wallet project side and server side. When the centralized wallet is conquered by hackers, users will suffer unnecessary losses
decentralized wallets, commonly known as onchain wallets, have private keys maintained by users and assets stored in blockchains
decentralized wallets are often referred to as onchain wallets. The private key is handed over to the user. If the private key is lost, the wallet will not be able to help the user recover, and the funds will be lost forever. But the decentralized wallet is difficult to be attacked by hackers, and users don't have to worry about the self stealing of the wallet service provider
centralized wallets are where assets are stored, while decentralized wallets are where private keys are stored
except for the exchange, it is not recommended to use the centralized wallet, although losing the private key may help you find it. But there is always a risk that the company will run

a decentralized wallet is equivalent to a channel, a channel to control its own assets on the blockchain by mastering mnemonics. For a decentralized wallet, the most important thing is to protect the security of the [private key]

the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

3. 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.

4. The decentralized blockchain currency wallet we use is actually just a blockchain software. Your currency is not stored in the wallet company, nor in your mobile device. It is still in the address of the blockchain network. The wallet just shows you all kinds of code of the blockchain through the server, establishes a channel to send all kinds of operation instructions to the blockchain. Blockchain application is very hot now. There is a SMIC blockchain service platform project initiated by Changsha high tech Zone, which is blockchain + public service mode, and is soliciting enterprises to join the chain.

5. 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.

6. 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.

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

8. 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~

9. 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.

10. Yes, with the popularity of the concept of blockchain, the popularity of blockchain assets, and the use of digital assets, blockchain wallets become something that everyone holds, similar to bank cards and so on
