Digital currency wallet with financial management
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 you1. 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

Recently, Huawei and tpcast jointly completed the instry's first cloud VR service verification under 5g experimental network, realizing real-time cloud rendering of interactive CG (computer graphics) VR content, which is a revolutionary progress in the history of VR instry
from last year to this year, Huawei cloud seems to have sprung up. We can always see Huawei cloud's achievements in the media
according to the data on Huawei's official cloud website, Huawei released its cloud strategy in 2010, and then officially released its cloud operating system fusionsphere after three years, and there has been no substantial progress in the next four years. It was not until Xu Zhijun, vice chairman and CEO of Huawei, announced the establishment of cloud Bu ring the Huawei China ecological partnership conference in March 2017 that Huawei began to make full use of cloud computing and achieved rapid development
it can be said that Huawei cloud really started in 2017, which is quite late in the highly competitive cloud computing market, but the rapid progress of Huawei cloud is obvious to all, isn't it surprising for many people
coincides with the critical period of instry upgrading
public cloud has been developing for ten years in the world, and the first batch of customers are mainly Internet enterprises. In this generation of public cloud, Amazon, Microsoft and Alibaba have obvious advantages. But at present, two changes have taken place in the market: first, more customers of traditional enterprises or government agencies begin to migrate to the cloud, transforming the traditional architecture with cloud computing, big data and artificial intelligence technologies, and enjoying the dividends of these new technologies. Second, the last generation of public cloud has been developing for ten years, and the technology and architecture are facing upgrading. Especially with the help of a new round of artificial intelligence tide, it is the general trend for enterprises to go to the cloud, and creating cloud ecology has become the top-level construction goal of the cloud instry
It has such instry-leading data processing capabilities, but it does not touch data, which includes three sentences: the first sentence: Huawei does not use technical means to obtain customer data in the background, and recognizes the data sovereignty of the enterprise; The second sentence: Huawei does not commercialize customers' data and will never force enterprises to exchange data with Huawei; The third sentence: Huawei will open up its cloud and big data capabilities to help enterprises process data and give full play to the value of dataas we all know, the data on the public cloud is the most sensitive topic in the whole instry. Huawei has been emphasizing "don't touch data" since its first day. Under the guidance of this strategic idea, Huawei has won the trust of a large number of partners in a short time. By the end of 2017, Huawei cloud had nearly 2000 ecological partners. With the help of so many partners, it is impossible for Huawei cloud to be strong
"action group" corporate culture
people who know Huawei all know that this company is a typical "action group": if you don't do what you want to do, you have to do it, do it with all your strength, do the best, and do it to an incomparable degree. This is true of Huawei's enterprise business and Huawei's consumer business, which have continued to rise in recent years. Now it's Huawei's turn to cloud business
in any instry, it is the doers who really decide the direction of the instry, which is exactly where Huawei's culture lies. Huawei cloud Bu has been formally established for just one year, which not only shows its strength and sincerity to the instry, but also shows its low-key, pragmatic and honest attitude
on December 17, 2017, Huawei cloud and Tuowei Information System Co., Ltd. established cooperation to build nine public cloud instry solutions for the government and enterprises based on Huawei cloud; On January 27, 2018, Huawei cloud and UFIDA cloud jointly released four general enterprise services: Marketing cloud, collaboration cloud, tax cloud and U8 cloud; In February 2018, Huawei cloud officially released the deep learning service and blockchain service BCS; On March 15, 2018, Huawei cloud announced the opening of a Hong Kong data center to help enterprises reach the world and innovate in the future
the data shows that the number of Huawei cloud services has increased from 45 in 10 categories at the end of 2016 to more than 100 in 14 categories at present, including more than 60 solutions such as manufacturing, healthcare, EI enterprise intelligence, e-commerce, sap, HPC high performance computing, IOT, etc. Since the establishment of cloud Bu, the number of users and resource usage of Huawei cloud have increased three times
according to the market report from IDC, Huawei's cloud government cloud solutions are among the leading manufacturers in China's Government cloud market; Fusioncloud's private cloud solution ranks first in China
