Digital currency wallet Chengdu Software
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 youdigital currency has four common functions: "scan code to pay", "remittance", "collection and payment", "touch one touch"
the pilot cities are Shenzhen, xiong'an, Cheng and Suzhou
the glorious revolution. The king's name is William III and Mary II. Mary is the daughter of James II of the Stuart dynasty. William III was originally in power in the Netherlands. Mary's husband also has the blood of Stuart family. James II is a Catholic, trying to restore the status of Catholicism in England. When James II ascended the throne, he was very old. At that time, it was generally believed that his Protestant daughter would inherit the throne after James II died (when James had no son). The Whig party, which controlled the Parliament, thought that this would not affect the status of the Church of England, But later, James II united with the king of France to try to restore the status of Catholicism in Britain and the power of the king. At that time, Britain and France were hostile to each other, and Louis XIV's foreign expansion policy made the Netherlands, Britain and other countries united against France. James II's practice intensified the conflict between the king and the parliament. During this period, James II got a son in his old age, which made England under the leadership of a Catholic king in the future. Worried that it would harm the interests of Britain, Parliament planned to make Anne and William king of England. On the other hand, it was ring the so-called great alliance War (the nine-year war, see Cambridge Modern World History, omitted here) that William, the ruling Dutch, urgently needed the strength of Britain to help him fight against France, so that his plan could be carried out. James II fled to France and Ireland when he learned that the Parliament had given William the throne. With the support of France, he organized an army to attack the British army. Later, he was defeated in Ireland and fled to France. Later, the British Parliament passed a series of laws to consolidate this form. The British double king rule lasted until 1694 (Mary II died). In 1702, Anne, another daughter of James II, succeeded to the throne. After Anne died, the throne was transferred to Hanover, Germany, and the Stuart dynasty ended.
1. Security risk of running environment
the core file of encrypted digital currency Wallet - private key / mnemonics is stored on the terminal device, whether it is PC or mobile terminal, if the terminal device appears unsafe phenomenon, There is a very high security risk for the private key / mnemonic
at the beginning of design, a secure digital wallet can avoid the possibility of private key / mnemonics being stolen e to the running environment. The security problems of the running environment on the terminal mainly include virus software, operating system vulnerabilities and hardware vulnerabilities
2. The security risk of network transmission
the security of network transmission is more reflected in the ability to resist man in the middle attack. Man in the middle attack means that the attacker creates independent contact with both ends of the communication and exchanges the data they receive, so that both ends of the communication think that they are talking directly with each other through a private connection, but in fact the whole conversation is completely controlled by the attacker
although most digital wallet applications use the HTTPS protocol to communicate with the server, the man in the middle attack method is to get the content of the HTTPS protocol by installing a digital certificate in the user terminal
a secure digital wallet needs to be able to scan the legality of all the digital certificates in the terminal, check the proxy settings in the network transmission process, and ensure the security of the basic network communication environment
in the development of digital wallet, whether to use two-way verification for communication verification at the network transmission level is also an important criterion to measure the security of a digital wallet application
3. The security risk of file storage mode
for the private key / mnemonics of digital wallet, the storage mode of terminal device also needs to be paid attention to in the security design. The access right of private key / mnemonic file directory, the form of private key / mnemonic file storage and the design of encryption algorithm all need to be strictly designed
when we analyze the security of several mainstream digital wallets, we find that even the well-known digital wallets are random in the storage of private key / mnemonic words. There are both plaintext storage and encrypted storage, but the decryption key is fixed in the code, which can not play any role in security defense
4. The security risk of the application itself
the security risk of the application itself mainly focuses on the security defense of the application installation package itself
whether the application installation package has the ability of anti tampering is a very core technical ability. In addition, memory security, anti debugging ability, life cycle management of private key / mnemonics, security of debugging log and security of development process also need to be enhanced
5. Security risk of data backup
if the mobile application can be backed up, it can use the machine with more powerful computing performance to brutally crack the private key / mnemonics. For example, if android:allowBackup Property is set to allow backup, then the backup mechanism of the system can be used to back up the application data files, and the private key / mnemonics of the encrypted digital currency will be backed up to the external media, which breaks the security boundary design of the operating system from another direction
for the majority of users, the security of digital wallet also means the security of wealth, so we must be careful when choosing digital wallet
I have used several wallets such as coin letter socoin and coinplus
in terms of personal experience, socoin and coinplus are very simple and easy to use. They are not only decentralized multi-functional cross chain digital currency wallets with social functions, but also integrate Multi Chain multi currency wallets, payment and settlement platform, currency trading platform, social groups, information market and other functions, which can meet almost all your needs for digital currency in one stop.
Generally speaking, the user experience of light wallet is relatively good. Generally, it supports multiple chains and is easy to operate. Light wallet has been used geek wallet , which is not bad. It supports BTC, EOS, ETH, usdt and other mainstream currencies
if the amount involved is relatively large and it is stored for a long time, it uses hardware wallet, which is relatively safer than light wallet and needs to buy hardware, The operation is relatively complicated
in terms of personal experience, qbao network is very simple and easy to use. It integrates multiple functions such as cross chain multi currency wallet, payment and settlement platform, currency trading platform, social group, information market, DAPP, etc., and can meet almost all your needs for digital currency in one stop
it is recommended to download and try.
1. Digital currency Wallet: bitcoin, imtoken, TP, wheat, tiger amulet, etc
2. Trading software: Fire coin, currency security, whale exchange, okex, etc
3. Information market: Babbitt, golden finance, mytoken, currency, etc
generally, these three categories are enough, which can make you pay attention to the market information at any time and react quickly, while preserving your assets. As for which one to choose, you can download and try which one is suitable for you.
I know, such as ngoex, Huo coin, okex. Huo coin's app is not easy to use. Okex's app has also had problems. I don't know what's specific. Anyway, I've experienced ngoex exchange, and I think it's very good. I've been in ngoex all the time
this is just my opinion
