Introduction to digital currency wallets

What is a digital wallet?

A wallet is a software that holds public and private keys associated with the Chinese blockchain. These keys are used to send and receive digital data in the Chinese blockchain and track digital currency account balances. If you want to use Bitcoin or any other digital currency, be sure to go for one wallet You will need digital.

How do these wallets work?

Millions of people around the world use digital wallets, but there is a lot of confusion about these wallets in the digital currency community. Unlike regular wallets, digital wallets do not contain any amount of physical currency. In fact, digital currencies are not stored anywhere physically. All information about their existence and transactions is stored on the blockchain.

Digital currency wallets are usually software that holds your public and private keys and is actually the interface between you and Blockchain Are different; Therefore, the user can check the amount of currency available, send or receive money and perform other related operations. When someone sends you bitcoins or any other digital currency, they are actually transferring ownership of those currencies to your wallet. In order to send digital currency, the private keys stored in your wallet must match the public addresses associated with your currency. In the meantime, there is no physical transfer of currencies. The transaction is done as a report of the transaction on the Chinese block and you see it in the change of your digital currency account in your wallet.

Different types of digital wallets

There are several types of wallets with different methods of storing and accessing digital currencies. Wallets can be categorized into three categories: software, hardware, and paper. The type of software can also be in the form of applications on your computer and laptops (desktop), mobile phone, or online.

Desktop: In this type, you can use it by downloading the wallet and installing it on your computer and laptop. These wallets can only run from a specific system, which is the system that downloaded it. These types of wallets have high security, but if your computer is infected or hacked, there is a possibility of losing funds.

Online: These wallets run online and you can access your wallet from any device and anywhere. Although these wallets are easy to access, your private keys are stored online and by third-party applications, thus protecting against theft and hacker attacks.

Mobile: Wallets that run on your mobile phones are very useful and can be used anywhere, including shops. These applications are usually designed to be smaller and easier to use than desktop models because space on mobile phones is more limited.

Hardware: These wallets differ from software examples in that they hold individuals’ private keys in a hardware context. These wallets receive transaction information online, but the information is stored offline, which increases their security.

Hardware wallets are compatible with web-based user interfaces and also support many digital currencies, depending on the type of currency and the user interface you use. Users can easily transfer their currency and receive a confirmation by connecting the device to an Internet-connected computer and entering a password. Digital wallets, while keeping you safe offline, also provide easy currency transfer.

Paper: These wallets are easy to use and give you extremely high security. From the name of these wallets, it can be assumed that they are your private keys that are printed on paper, but these wallets are actually software that is used to securely produce multiple keys and print them on paper. These types of wallets are also very easy to use. The transfer of different currencies to your paper wallet is done through public addresses that Paper wallets have been marked. In addition, if you want to spend these currencies, all you have to do is transfer them from the paper wallet to the software wallet. This so-called “wipe” can be done manually by entering digital keys or scanning the Q-code on the wallet.

Are wallets digitally secure?

The security of these wallets has different ratings. Their level of security depends on the type of wallet used and your service provider. A web server is less secure than offline examples. Online wallets are exposed to a wider range of risks that, due to their online nature, can become a good prey for hackers. Offline wallets, however, are not hacked by hackers because they have limited internet access and are not affiliated with any third-party developers.

Although the experience has shown that online wallets are more vulnerable to hacker attacks, it is necessary to consider appropriate security measures for all wallets. Remember, regardless of the wallet used, losing your private keys means losing your money. However, if you send your money to the wrong person or are hacked, there is no way to claim money loss and return the transaction. Therefore, you must be very careful.

Support your wallet. Keep only a small amount of the currencies you use daily online. Keep most of them in a very secure environment on your computer or mobile phone. Options for backing up offline cash registers or paper wallets or USBs can be done in ways such as Legernano; This will protect your wallet from potential computer malfunctions and recover your wallet if it occurs. Although this will not deter stubborn hackers; In fact, by choosing online wallets, you run the risk of being hacked all the time.

Update your software. Always provide the most secure environment available to you by updating your software. Keep not only your wallet up to date but also your computer and mobile phone systems.

Security layers Add more. The more layers, the better. Using long and complex passwords and ensuring that money transfers from your address require a password can be additional solutions to increase the security of digital currencies. Using high-profile wallets with the ability to authenticate in two steps and requesting an additional password while running the software are other measures to increase security. You may also want to use “multi-signature” wallets such as “Armory” and “Copy” wallets. Despite this feature, for each transaction, another user or even several other users must confirm the transaction.

Ability to use multiple currencies or just one?

In addition to Bitcoin, which is currently the most famous and popular digital currency in the world, there are hundreds of other digital currencies ‌They also exist with unique ecosystems and structures. If you want to use other digital currencies as well, the good news is that you do not have to use a separate wallet for each. Instead, simply use a wallet that can support multiple currencies; These wallets allow you to use multiple digital currencies with one wallet.

Is there a charge for transactions?

There is no clear and complete answer to this question.

In general, transactions are a small part of the transaction received in traditional banking. Fees are sometimes received as processing fees for specific transactions on the network, while some transactions do not include any fees. It is also possible to create your own fee. For example, for a 226-byte transaction, you will be charged a fee of up to 12 cents. In some cases, if you choose a lower fee, your transaction may be done with less priority and you will have to wait for hours and maybe days to confirm your transaction. If you need your transaction done quickly, you need to increase the amount of commission you want to pay.

Of course these days Bitcoin transactions have increased a lot And the network fee is significant in its kind.

Are digital wallets anonymous?

Both yes and no. You are known by your usernames on your wallet. You do not have to enter your original information, and all your transactions will be publicly and permanently recorded on the blockchain with the same information entered. Your name or street name will not be recorded on the blockchain, but information related to your wallet address can be traced in a variety of ways. There are ways to increase your anonymity, but you can never completely hide your identity. Recently, projects called Dark Volt have promised users to conduct their transactions in the Chinese block anonymously. This project does this using QuinnMix methods and using anonymous addresses.
