有人让我下载软件做区块链是真的吗,有人拉你做区块链

A. Several of my friends are playing with blockchain. Is it reliable?

Blockchain is also a relatively new thing, and there are many. People are paying special attention to blockchain. Blockchain can be loved by many people and can also receive investment from many people. Many people particularly want to invest in blockchain and hope to use it by investing in blockchain. Get more bang for your buck.

There are many people who want to invest in the blockchain, but they may not necessarily understand the blockchain, and they do not know how to operate the blockchain. If everyone around them invests in the blockchain, they themselves If you invest, you may suffer relatively large losses. Some people may have this question: Several of my friends are playing with blockchain, is it reliable? In fact, I think blockchain is not necessarily reliable. There are three main reasons why I say this:

First, blockchain is easily affected by the market.

The reason why I think blockchain is not necessarily reliable is because I think blockchain is easily affected by the market. When the market fluctuates greatly, the value of blockchain may increase. decline, and it may not be able to recover as soon as possible. If some people invest because of the value of the blockchain, they may suffer relatively large losses, and they may lose all their money.

The above is my opinion.

B. Qubu scam Qubu App blockchain scam revealed

According to Qubu official introduction, Qubu App is a health App based on blockchain technology. Its core selling point is “make money while walking”. It is understood that the number of Bu App users has grown to 30 million, but many users say that Qubu App is a blockchain scam. So what is the Qubu scam? Let’s take a look below.

Qubu claims to be an innovative technology company supported by blockchain technology and based on the field of sports and health, encouraging all people to pay attention to their own health and participate in happy sports. However, industrial and commercial information shows that this company with 20 million members has a registered capital of 3 million and a paid-in capital of 0.

From the background of the shareholders, although the company’s business license includes research, development, consulting, etc. on blockchain technology, the two shareholders have no resume in the blockchain field. Ye Zhuang, the company’s executive director and general manager, has served as legal representative in five companies. The previous four companies included steel, wine, fresh food and bicycles, all of which had nothing to do with blockchain.

Among the 50 recruitments the company has done before, there are no positions involving blockchain research and development. The one with the largest number of recruits and the highest salary is the recruitment of city partners, with a monthly salary of 30,000-60,000 yuan. Team and promotion experience required.

Various signs indicate that Hunan Qubu Network Technology Co., Ltd. has nothing to do with blockchain technology. Some market participants said that this APP is a pyramid scheme at first glance.When done by an experienced team, software development may use an outsourced technology team. According to market conditions, the cost of developing such a capital disk software is only about 120,000, which is equivalent to 6,000-7,000 candies. The development cost is negligible.

At present, the headquarters of Qubu Company has moved from Changsha, Hunan to Bishan District, Chongqing. A company that claims to have 30 million users actually moved its headquarters to a local community and county, which makes people question it. It is understood that Qubu’s Changsha headquarters had previously been investigated by the Changsha City Market Supervision.

D. How to develop blocks into blockchains

1. Block development The software Go is needed for the blockchain. Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
2. Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust", created a reliable "cooperation" mechanism, and has broad application prospects.
3. From a technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency. TheseThe characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

E. Block How to apply blockchain How to apply blockchain

1. Financial field:

Blockchain has potential in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. of great application value. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby quickly completing transaction payments while greatly reducing costs.

2. Internet of Things and logistics fields:

Blockchain can also be naturally combined in the fields of Internet of Things and logistics. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.

3. Public service field:

Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralized characteristics of these fields are also It has brought about some problems that can be transformed using blockchain. The decentralized, fully distributed DNS service provided by the blockchain can realize domain name query and resolution through point-to-point data transmission services between various nodes in the network, and can be used to ensure that the operating system and firmware of an important infrastructure are not Tampered, you can monitor the status and integrity of the software, detect bad tampering, and ensure that the data transmitted by systems using IoT technology has not been tampered with.

4. Digital copyright field:

Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the ownership of works. Authenticity and uniqueness. After the rights of the work are confirmed on the blockchain, subsequent transactions will be recorded in real time, realizing full life cycle management of digital copyright, and can also be used as a technical guarantee in judicial evidence collection. For example, MineLabs, a startup company in New York, USA, has developed a blockchain-based metadata protocol. This system called Mediachain uses the IPFS file system to realize copyright protection of digital works, mainly for copyright protection applications of digital pictures.

5. Insurance field:

In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. through smart contractsThe application requires neither application by the policy holder nor approval by the insurance company. As long as the claim settlement conditions are triggered, the policy will realize automatic claim settlement. A typical application case is LenderBot, which was launched in 2016 by blockchain companies Stratumn, Deloitte and payment service provider Lemonway. It allows people to register customized micro-insurance products through the chat function of Facebook Messenger, providing services between individuals. The high-value items exchanged are insured, and the blockchain replaces the third-party role in the loan contract.

6. Public welfare field:

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

F. I just met a friend who asked me to do blockchain. He has a link and QR code to do blockchain software. Is he a scammer?

Be careful. Nowadays, scammers are all scammers. They are extremely clever, and some scams are linked to each other, making it difficult for people to detect them. You can tell your friends to think about it first and then learn more about the specific situation.

G. How to develop blockchain mobile wallet app software

Rely on third-party platforms

Clear your own needs, understand the code, and be familiar with the development process

p>

Complete process of APP development

Early stage of APP development

Developing mobile APP requires understanding of product positioning

Determine the needs for APP development and position the APP . To develop and produce an APP software, you need to first understand the needs of the Bizhenlan App application market. This is a hard standard

Evaluation

Try to be as detailed as possible about the overall situation of the project , evaluate whether the APP development project can be completed within the specified time limit, and evaluate whether the required functions can be realized. This is a crucial point for whether a mobile APP can ultimately survive under the strategic direction of the enterprise. During the APP development process

Determine the prototype of the APP

Including user experience design (UX), the interaction logic of the APP interface, and the general status of the implementation of the APP function points

Have a clear positioning of the APP and build an APP prototype. Start UI design and design the user interface. The user interface is where APP users interact with your APP. It should be simple and beautiful. , the principle of convenience can bring a higher experience to users. A complete APP needs an idea that attracts users' attention, which requires developers to have unique insights in creative planning

Excellent sample display

The display effect of high-quality samples is In order to allow enterprises to visually see the prototype of an APP, this also saves a lot of later code development.of time and energy.

Native code development

After UI design and sample presentation, the APP code development stage officially enters. At this stage, all early display effects are realized and developed natively through the APP code.

Deeply study what you don’t understand about APP development

The technology of APP development and customization is constantly being renovated and developed. APP developers will often encounter new problems during the development process. The functional requirements for APP development must not only be integrated with the existing functional system, but also make the newly developed APP functions unique.

Understand the system compatibility of the APP

When developing mobile APPs, you must know that the styles, layouts and navigation of Android and iOS are very different, which requires matching every aspect of creating an APP project. operating system to satisfy users. At the same time, for Apple apps, it requires applications designed and developed specifically for the operating system.

Developing mobile APPs requires continuous testing

Customized APPs require continuous optimization and testing, instead of getting the results after one or two APP production tests, directly putting the undeveloped and perfect The launch of APP software is irresponsible to the company and to users.

After the APP development is completed

Product testing is launched

After the code development is completed, it enters the stage of testing and later launch. This is a gradual process. After all bug testing is completed and it is confirmed that there are no bugs, it can be launched on the Apple market and Android market.

Project delivery is completed

After the APP development and testing is online, the source code, documentation, and operation documents will be delivered to Party A in accordance with the provisions of the contract.

Online operation and promotion

After a successful launch, the APP can develop the number of users through the company's own operation and promotion, making it stand out in the industry. Of course, if there are bugs later, or updates can provide follow-up services. Only by constantly advancing with the times in operation and promotion, and maintaining and updating can the APP survive forever.
