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. And it is a multi currency Cross Chain Wallet, which supports BTC, BCH, LTC, ETH, etc, dash and erc-20 series of tokens. At present, it is the most complete currency digital currency wallet in the true sense
anmao wallet is the only digital currency wallet that supports Chinese mnemonic words. It is composed of 12 Chinese characters, which is convenient for memory and in line with Chinese reading habits
the biggest feature of anmao wallet is that it well applies the scalability of light wallet. While managing a variety of digital assets, it has embedded DAPP list and anmao fishpond mining game. The tokens are directly stored in the wallet, which is convenient, labor-saving and interesting. It can be said that it is a money making wallet
with embedded Android block browser, each transaction can be queried in real time by using transaction address, block height and transaction ID, which is accurate
there are also market and information DAPP, a multi-functional digital currency wallet
bitpai
bitpai wallet is a new generation of blockchain asset integrated service platform developed by bitpai team. It is based on HD wallet technology, multi signature and on chain transaction. It can easily and safely use digital currency and easily send and receive bitcoin on bitpai. At present, the main supported currencies are BTC, BTC, ETH, some erc2.0 tokens, qtum, HSR, dash, safe, LTC, LCH, Zec, etc and Doge
bitpai supports multi address coin issuing, built-in OTC and exchange (third-party service), and can trade with users from all over the world, which is more suitable for professional users with frequent transactions and OTC trading needs
in terms of security, the user controls the private key. After the transaction is completed, the coin is directly kept by the user. If it does not operate for a long time, bitpie will automatically lock, further improving the security of the wallet
disadvantages: for initial users, too many and complex functions are a kind of burden. They only need to send and receive digital currency simply. Too many complex functions increase the learning time cost of users and affect the experience of wallet users
atoken
atoken is a mobile wallet supporting multi currency cross chain exchange, which is safe and convenient. At present, it supports BTC, LTC, ETH, etc, Doge, EOS and other main chain currencies; BCD, BTG, BCH, SBTC, etc; Support all tokens of ethereum erc20
users hold their own private key, which is stored in app with multiple encryption. They do not access the server in any form, and no one else can touch your digital assets; The wallet adopts 5-layer HD, horizontal isolation and vertical defense architecture; Pbkdf2, sha-512 and other encryption algorithms are used. At the same time, atoken implements the transaction acceleration function of wallet and supports the transaction acceleration of bitcoin and Ethereum
disadvantages: there is no market information in the wallet, which is inconvenient for users to use.
in terms of cloth storage and mining, I recommend Heshu hardware wallet and jiajiabao intelligent home miner. The core advantage of the proct is safety
take sum hardware wallet as an example. The advantages of sum hardware wallet are as follows:
1. The private key seed is encrypted layer by layer, physically isolated and never touched the Internet.
firstly, when creating the wallet, the seed password is generated and stored in the local encryption chip, and the 10 bit payment password is required
then, the transaction is made in the wallet. At this time, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, which is physically isolated and never touches the Internet. There is no need to worry about my password being stolen by hackers
Second, the bank system verifies the financial level motherboard and encryption chipuses the bank system to verify the financial level motherboard, and the private key seed is stored in the chip. If the proct is stolen or lost, and destroyed by malicious violence, the chip will trigger a self destruct circuit, and immediately permanently and irrecoverably delete all the information in the area
Third, it supports the withdrawal of global bitcoin ATM, which is convenient and fastthe reason why digital assets attract the attention of many fields in the world is that it is creating a global fast circulation, and the larger the circulation field is, the wider the scope is, and the higher its use value is. The core of digital assets is the medium it acts on among currencies. The Heshu wallet has built-in many mainstream exchanges in the world. It can trade digital assets anytime and anywhere. With one machine in hand, it can walk around the world without worry, and no longer have to worry about exchanging foreign currency
Different from conventional digital wallets, multi signature wallets need the authorization of multiple key holders to transfer digital currency, so the security of multi signature wallets is higher. Ordinary Wallet: a wants to transfer a bitcoin to X. A only needs his signature (using the private key) to complete the transaction. Sum Wallet: if a wants to transfer a bitcoin to x, a multi signature verification is set (at least two signatures of Abc3 indivials are required to transfer the money), then a needs B or C to complete the signature (using the private key) when a wants to transfer the money to X. I hope I can help you. Thank youwhen transferring money, the receiver only needs to send the address of the wallet to the other party, and the other party can transfer the digital currency to the address. When trading in the exchange, the user should also enter the digital currency into the address designated by the exchange, that is, the wallet, to complete the transaction. At the time of withdrawal, the exchange will also enter the digital currency into the user's wallet address accordingly. This is how the money should be transferred to the wallet.
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 toolsthe 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 recordsbut 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:
