A. The value of wallet to blockchain

For entrepreneurs, wallet development is at the infrastructure level in the blockchain industry ecological map and belongs to In the subdivision of digital asset storage, the technical threshold is relatively high.

Many users who have never used a digital wallet have almost no idea about it, and even think that digital wallets are just for "storing" digital currencies. This article gives a rough definition of a wallet. A wallet application has a series of key pairs, and each wallet address corresponds to a key pair - a private key and a public key.

The private key is untestable and non-repeatable and therefore unique. And the private key has ownership and control of the wallet and is used to sign and verify every transaction. In order to lower the user's threshold for use, the private key also has another form of expression - a mnemonic phrase to help users remember complex private keys.

How is the private key related to the public key? It generates a public key through a certain encryption algorithm, so that the private key corresponds to the public key one-to-one. The encryption algorithm is one-way, that is, the private key can derive the public key, but the public key cannot derive the private key. Therefore, it can be understood that mastering the private key is equivalent to mastering its ultimate control.

Security issues of digital wallets

First of all, everyone must know that digital wallets are decentralized, and most hot wallets inherit this attribute. Since the private keys are managed by the users themselves, they cannot be retrieved if lost, and transactions cannot be rolled back, making many users feel unsafe.

Here are ten wallet usage suggestions given by industry experts:

[if !supportLists]1. [endif] Use a backup wallet;

[if !supportLists]2. [endif] Do not transfer private keys to others at will;

[if !supportLists]3. [endif] Do not use WeChat collections or cloud backup to store private keys ;

[if !supportLists]4. [endif] Cannot take screenshots or take photos to save private keys;

[if !supportLists]5. [endif] Cannot use WeChat or QQ Transfer private key;

[if !supportLists]6.   [endif]Do not choose email or cloud storage private keys;

[if !supportLists]7. [endif]Do not use wallet applications from unknown sources provided by third parties;

[if !supportLists]8. [endif] Avoid Apple IDs provided by others;

[if !supportLists]9. [endif]Do not send private keys to the group;
< br /> [if !supportLists]10. [endif]Do not import private keys to unknown third-party websites.

Security is the foundation of digital wallets, as well as cryptocurrency and even the entire blockchain industry. In addition to ensuring the complete functions of the wallet, wallet developers should also pay attention to security.

How to manage digital wallets

We should pay attention to several issues about wallets:

[if !supportLists]First, [endif]Private The key determines the property rights of the digital currency you own and must be managed properly by yourself.

[if !supportLists]Second, [endif]The public key is public and the address is also public. Anyone who transfers coins to your address can only truly own the coins if they control the private key.

[if !supportLists] Third, [endif] The transaction flow is stored on the blockchain and has nothing to do with the private key address. The transaction accounts are public, and as long as you know the address, you can check how much the corresponding digital assets are.

[if !supportLists] Fourth, [endif] If the wallet installed on a mobile phone or computer or other equipment, the backup key or mnemonic phrase is damaged, lost, stolen, etc., you should immediately reset it through Install or transfer assets to other wallets.

[if !supportLists] Fifth, [endif] No matter what kind of wallet it is, it is relatively safe. There is no absolute security. The private key or mnemonic phrase must be backed up and kept, and it is portable. It is difficult to have both.

How digital wallets work in commercial banks

  It was previously reported that the People's Bank of China has a two-layer architecture design for digital currency, and the central bank is also preparing to issue digital currency.

Bank accounts and digital wallets of commercial banks have common management aspects. In this case, bank accounts and digital wallets are positioned differently. Then according to the wallet standards designed by the central bank, the wallet is a safe deposit box. The bank will manage the customer's safe deposit box according to the customer's requirements, which can be said to have all the attributes of cryptocurrency. So in this framework, the ID field of the digital currency wallet is added to the bank account. In this case, the digital currency wallet not only functions as a safe deposit box, but also does not participate in business, avoiding affecting the core business of the bank.

Digital currency transfers can be transferred directly in the commercial banking system, or through the issuing bank using a client digital wallet for direct point-to-point transactions. In this case, there is no need to rely on inter-bank payments between account banks.

The current competitive situation of digital wallets

The first is the competition for traffic, mainly to attract new users and promote activation, in order to have a large user base.

The second type is competition in gameplay, mainly reflected in community rewards, in order to enhance user stickiness.

Another option is to expand more extensive services, such as CTGPay, which can realize functions such as currency exchange and financial management with different countries. It saves users the trouble of exchanging currency and managing multiple legal currencies, and also greatly expands the application scenarios of digital currencies. Financial management can also guarantee an income of about 5% per month, so it is very popular among users.

The value of wallets to blockchain

The purpose of wallets is to store private keys. As mentioned at the beginning, it is not to store cryptocurrency. It can be said that as long as you have a 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 scenario applications. And other issues. To put it simply, tokens developed based on different public chains require their own wallets.

Summary

If you still stay in the competition for basic functions, you will undoubtedly be left behind. Today's digital wallets should pay attention to building an ecosystem that covers multiple functions such as user community, transaction, interaction, financial management, etc. In order to have a large user base and ensure extremely high daily activity.

D. The difference between tp wallet and exchange

Digital currency trading It refers to the over-the-counter trading of digital currency transactions.

The over-the-counter trading market is where most transactions in the global financial system occur. Digital currency exchanges are divided into centralized and decentralized Two types. Decentralized exchanges trade on the chain, users conduct peer-to-peer transactions, and the assets are always in the hands of the users.

Newdex and WhaleEx are decentralized exchanges. Centralized exchanges are not peer-to-peer transactions. Instead, transactions are matched through the platform. The coins of both buyers and sellers are stored on the platform, and after the transaction is completed, the assets are transferred to their own decentralized wallet addresses through withdrawal. Huobi and Binance are centralized trading platforms.

tp wallet (blockchain wallet): Simply put, a cryptocurrency wallet is a tool you use to interact with the Blockchain. Existing cryptocurrency wallets can be divided into three types: software wallets and hardware wallets As well as paper wallets. They can be divided into hot wallets or cold wallets based on their working mechanism.

Most crypto wallets on the market are software-based, which makes them easier to use than hardware wallets. However, hardware wallets are more secure than other types. On the other hand, paper wallets, in which the "wallet" is printed on a piece of paper, have become outdated and unreliable.

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 is Centralized wallet.

At the same time, the cryptocurrency wallet also includes a public address generated based on the public key and private key, which is a set of alphanumeric identifiers. This address essentially represents a specific "location" on the Blockchain that can be used to receive cryptocurrency. This means you can share your public address with others to receive funds, but remember not to reveal your private key to anyone.

E. Is blockchain wallet safe?

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 become a means of making money. So you must be very vigilant about this aspect. Anyway, I personally don’t believe it.

F. What does blockchain clip mean?

It is a blockchain wallet. A blockchain wallet is actually a management tool that contains private keys, public keys, addresses and block data. With the private key, you can have control over the digital currency on the corresponding address. Losing or forgetting the private key means losing control of the currency on the corresponding address.

Blockchain wallet is a tool used to help you store, manage, and trade digital currencies. Currently, our most commonly used blockchain wallets are mainly Bitcoin wallets and Ethereum wallets. Using the digital currency payment address generated in the wallet, you can receive digital currencies forwarded to you by others, and you can also transfer the coins in your account to others.

G. Can I define the blockchain wallet address myself?

Hello, no. The blockchain wallet address is randomly generated when it is created and cannot be defined by you. But you can create a "pretty number address". The so-called pretty number means that the last few digits of the address are the same numbers, such as 8888 and so on. However, creating such an address requires a large amount of computing power and is somewhat difficult.

H. I would like to know about the blockchain wallet. Can someone introduce it?

Hello.
What operations can ordinary investors and users use the wallet to achieve.
When you think of a wallet, what comes to mind?
1. Hot wallet, cold wallet, observation wallet. ——Realize the most basic function of a wallet: storage.
2. DApp entrances to different public chains. ——The entrance for currency holders to dApps on various public chains.
3. Flash swap, enter the exchange for direct trading and cash out. ——Transaction and realization of digital assets.
4. Pay attention to the market - read the information and understand the currency price.
Yes, some blockchain wallets have already implemented these functions. It will give people a feeling of "small wallet, big world". The actions that users want to complete in the blockchain world can basically be solved in the wallet.
You can take the Tokenpocket wallet that I often use as an example.
1. How to understand hot wallet, cold wallet and observation wallet?
Hot wallet: It is an online wallet, an online wallet. It is convenient to withdraw coins, and you can also check the wallet assets, balance, transaction records, etc. at any time.
Cold wallet: It is an offline wallet. Since it is an offline wallet that is not connected to the Internet, how can I achieve it when I need to transfer or withdraw coins? Just watch your wallet.
Observation wallet: A wallet that observes the assets in the cold wallet and assists in withdrawing the assets from the cold wallet.
2. TP SDK integrates TRON
TokenPocket’s latest version of TP SDK now supports TRON, which means that when an independent dApp on the TRON public chain is connected to the TokenPocket SDK, TRON authorized login and data signature can be achieved , Token transfer, transaction signature and other operations.
In this case, the development of TRON’s independent dApp will be greatly accelerated.
3. Asset aggregation function
We usually have this phenomenon: everyone has multiple accounts, and these accounts all have the same token, and they want to pool the same assets on these different accounts To bring them together, the function of asset aggregation is needed.
There is a problem here: if the passwords for each of your accounts are the same, you only need to 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 collection operation is completed to prevent errors.
4. Experience the colorful dapps on each public chain
In the TP interface, select the TRON category to enter the Tron Dapp page. Play various Dapps, or enter other public chains, such as EOS, Jingtong, etc.
The wallet has more functions, waiting for further exploration.

I. How to transfer cash to blockchain wallet

Cash cannot be transferred directly to blockchain wallet.
A blockchain wallet is a digital wallet that allows users to store and manage cryptocurrencies such as Bitcoin and Ethereum; a blockchain wallet powered by blockchain is an electronic device that allows individuals to store and transfer cryptocurrencies. Wallets; Blockchain wallets charge dynamic fees, meaning transaction fees can vary based on factors such as transaction size.
Every blockchain wallet will have a wallet address, which is equivalent to a bank card account number. If you want to transfer money to the other party, just choose to send, then paste the other party’s wallet address, enter the transfer amount and your own transaction number Just enter the password and the transfer will be successful.
On the contrary, ifIf the other party wants to transfer money to you, you only need to give him your wallet address.
