Ⅰ How much does it cost to develop a blockchain wallet

The development cost of a blockchain project is generally estimated based on the technical difficulty. Basically, the development of a blockchain is approximately Between hundreds of thousands and millions. Development costs are primarily calculated based on the number of developers and the hours of work invested. If there is ready-made source code that can meet the functional requirements, then development can be quickly achieved by modifying and adding functions, so the price is very low.

In fact, all the costs are in website development, manual maintenance, and hardware consumption. The cost of website development is basically determined by the investor's functions. Generally, the more functions a website has, the more investment it will have.

II Which blockchain wallet is easier to use

With the development of the blockchain industry to this day, the underlying layer and technology have become very mature. So the blockchain wallets of each company will not be very different.

Whether it is easier to use, in fact, it mainly depends on security, supported currencies and optimization of experience. Essentially, blockchain wallets are divided into two categories: hot wallets and cold wallets (hardware wallets).

1. Hot wallets can be equivalent to software wallets to a certain extent.

The advantage is that it is simple to operate and easy to manage, and is more suitable for entry-level users.

But the disadvantages are also obvious. Every transaction requires online verification, and data security cannot be guaranteed.

The relatively well-known hot wallets on the market such as imToken, Math Wallet, etc.

2. Cold wallets generally refer to hardware wallets.

The private key of the cold wallet will never touch the Internet, and the private key will never enter the network. A hardware wallet is a specialized electronic device used to store encrypted assets. Its function is to store private keys in an internal chip. The private keys never leave the device, so they are safe. Therefore, general hardware wallets are cold wallets.

Advantages: The private key is generated through a mnemonic phrase and is permanently retained inside the hardware wallet. It will not be leaked out, so security is high.

Disadvantages: It’s not very convenient to use, it doesn’t matter if you receive it or not, you just need to provide an address for the removal. To send, you need to connect the device to your computer or mobile phone. So it is not as convenient to use as a hot wallet.

The first consideration when choosing to use a hardware wallet is security, so generally if you want to truly protect your assets, you must prepare a hardware wallet.

Currently, there is no hardware wallet with particularly complete currency coverage on the market, but there is a blockchain wallet called TJ Wallet, which is the first safe and reliable software and hardware ecological wallet supported by Filecoin in China. Triple hardware encryption supports mainstream currencies such as BTC, ETH, Filecoin, and supports the expansion of all currencies. It takes into account both convenience and security. It is a good blockchain wallet. The topic owner can pay attention~

Ⅲ Introduction to digital currency wallet development, blockchain digital wallet

The blockchain digital wallet system canCoin, Ethereum and other mainstream digital currencies are managed and stored in a unified manner, which means that all currencies are managed in one wallet, which greatly reduces the use threshold and management burden of digital currencies, and 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 in turn 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 eliminate The influence of centralization is to store data in different nodes in a distributed manner, ensuring the security of users' wallets and data, and removing 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.

IV What is the initial state of the blockchain wallet?

The virtual currency is deposited. The initial state of the blockchain wallet is to use a fixed rebate model to attract investors. The difference is that the deposits are virtual.Virtual currency is in a very primitive state of bartering, so the initial state of the blockchain wallet.
