2. Decentralized or cold wallets are relatively safe. The private key is backed up by itself and can be checked on all data links. As long as the private key is not leaked, the assets will not be stolen.

3. There are many digital currency wallets. Here are some wallets
anmao wallet
anmao wallet is a light wallet developed by Hangzhou anmao blockchain Technology Co., Ltd., which saves storage space compared with full node wallet.

The digital currency wallet is the hardware wallet, which means that the private key of digital assets is stored in a single chip, isolated from the Internet, plug and play. Hardware wallet can't guarantee 100% security. For example, if a geek gets your hardware wallet and doesn't know your private key, it may be cracked by violence. It's just one of the safest storage methods compared to other storage methods

many block chain entrepreneurs at home and abroad are optimistic about the development of this field, so they begin to build more hardware wallets. In the case of the exchange being stolen a lot of money and the software wallet being stolen from time to time, many investors regard the hardware wallet as the last moat

extended information:

whether the hardware wallet is safe

the hardware wallet can not guarantee 100% security. For example, if a geek obtains your hardware wallet, it may be cracked violently even if it doesn't know your hardware wallet immediately. It's just one of the safest storage methods compared to other storage methods

of course, there are exceptions, such as you have unlimited brain power and never forget. It's better to save it anywhere than in your own mind

5. It's a tool for managing and using digital currency.

6. The best platform to use digital money is Alipay and WeChat, which are relatively safe and easy to use.

Why develop digital currency? From the perspective of the central bank, there are six advantages:

first, to improve the convenience and transparency of economic transactions; second, to rece the high cost of the issuance and circulation of traditional paper money; third, to better support economic and social development; fourth, to help the comprehensive realization of Inclusive Finance; fifth, to rece money laundering, to promote the development of the economy and society Sixth, improve the central bank's control over money supply and circulation

steps of digital currency development:

the first step,

first, we need to download the source code of a blockchain system from git, such as choosing the backbone code of bitcoin to download the relevant source code

At the same time, prepare the corresponding compiling environment (c + + is recommended in Linux) and install the corresponding development environment and tools

the second step and

code all need to be compiled, so you need to prepare the compilation environment and tools, download the environment compilation tools, configure

system environment variables, QT environment and other files, and compile commands are described in detail in the files in ITC source code

however, the construction of the system and development environment, program compilation and other processes are cumbersome, so it is not recommended for ordinary users to make their own. For developers, it may take 2-3 days to install and configure for the first time

the third step,

take bitcoin development as an example, it is the development environment of Q. after downloading the source code and configuring the environment, open the source code of the bitcoin core in qtcreator, configure relevant files and compilers, and start to try to compile the client of the bitcoin core

Step 4,

transform into your own digital currency, open each source file, find the corresponding local adjustment parameters, such as adjusting

the number of coins in each block, the total output, the adjustment difficulty, and so on. Then the most critical point is to change the name to your own currency

name as you want, and don't forget to replace the related icons in the resource folder. If all goes well, after re compiling, your new coin will be invented successfully

for the development of this digital currency, the technology is relatively professional, so it is better to have a professional team to assist

framework for digital currency development:

1. Build Ethereum private chain test environment and public chain node environment configuration

2. Ethereum transaction and confirmation principle

3. Ethereum JSON RPC interface

4. Ethereum transfer and withdrawal principle

5. The server connects Ethereum public chain interface, and its own server stores business data, Public chain storage transaction anonymous data

6, private key security processing

the following is the development code example:

for example, the common digital currency wallets in the market are:

app class: kcash Imtokenweb: myethereumwallet Google browser plug-in: metamask

one of the most commonly used is imtoken

blockchain transaction technology concept:

let's take a look at how blockchain transaction is handled with bitcoin as an example. In order to send a certain amount of bitcoin to another wallet, you need the following information: the address to send the funds to your wallet, the amount of cryptocurrency you want to send

the ID of the recipient's wallet

each transaction is signed with a unique confidential private key. Once the payment is signed by the sender, it becomes publicly available. The transaction still needs to be confirmed so that the payee can get the money. In order to confirm the transaction, it is necessary to generate a new chain block

these blocks are generated by complex mathematical calculation to find the unique key. It takes 10 minutes to create a new block, and the person who finds the key gets a certain amount of coins as a reward. Once a new block of the chain is created, it is not possible to remove it from the database or change the information in some way. Therefore, blockchain transaction is final and irreversible

three core advantages of digital currency:

first, digital currency is a fair currency

digital currency has no specific issuing institution, is not issued by a country, only depends on a specific algorithm, which means that digital currency can not be manipulated by manipulating the number of issues, so digital currency is a free, non-state currency

we can see that there are many countries that directly recognize the virtual currency, so if there is a demand, it needs a trading platform

many investors who want to build a virtual currency trading platform now, why can't they go to these areas to build a trading platform? Building a virtual currency trading platform is a good business opportunity, isn't it

Second, the security factor of digital currency is higher.

although the emergence of paper money facilitates the transactions in our daily life, there are risks of being stolen and received. Although e-money can avoid these risks, there will be new problems such as theft and swiping

digital currency can avoid the above problems. And broadcast every transaction record on the network. Yes, all nodes save all the currency circulation information, so that any node can easily find the currency circulation before the transaction

Thirdly, the transaction of digital currency can realize anonymous transaction. Although you can query the flow information of each account according to the local complete transaction records

but we can't know who the owner of this account is, and no one has the ability to manipulate the digital currency on other people's accounts, which protects the privacy of users

if you also hold trading digital currency, foreign exchange gold, crude oil, contract Futures:

8. Now the most widely used in the market is the imtoken wallet. Open token.im to download and register. If it is an IOS system, it must be a Hong Kong or foreign ID to download and use, and the ID can be bought online.
