This is called blockchain.
The core advantage of blockchain technology is decentralization, which can be achieved through the use of data encryption, timestamps,Distributed consensus and economic incentives and other means realize point-to-point transactions, coordination and collaboration based on decentralized credit in a distributed system where nodes do not need to trust each other, thereby solving the high cost, low efficiency and data storage common in centralized institutions.

⑻ Foxconn makes mobile phones

On April 5, Israeli technology company Sirin Labs announced an agreement with FIH Mobile Co., Ltd., a subsidiary of Foxconn, which will be responsible for Sirin Labs’ Finney blockchain smartphones of production.

img src=' https://p26 . toutiaoimg.com/large/PGC-image/1523344436049884225 afeb '/

Foxconn is the world’s largest electronic equipment contract manufacturer, responsible for iPhone, Kindle and Electronic components for popular products such as PlayStation. Now, Foxconn is planning to expand into a new field -. This veteran company wants to bring cryptocurrencies to the masses.

Finney is the world's first blockchain smartphone that can securely store and use users' Bitcoin and other digital currencies, and provide related services. The most important implication is that Sirin has created a platform that allows virtual currencies to be truly used for trading, not just as a tool for speculation.

Sirin can also allow various virtual currencies to trade and circulate with each other, helping to integrate independent virtual currencies intoLinked to each other, through normal currency transaction circulation, a healthier financial ecology is formed. In the future, all countries plan to establish their own official virtual currencies. The emergence of Sirin has the opportunity to connect these emerging virtual financial systems and create a blockchain financial ecosystem that is comparable to real currency value.

img src=' https://P6 . toutiaoimg.com/large/PGC-image/1523344436115 CB 77 EB 421 f '/

In other words, Sirin represents more than just mobile phone products In itself, it is the establishment of a standard virtual financial trading platform. Although it currently only supports Sirin's own mobile phone system, if it accumulates a certain influence, this system will have the opportunity to cross over to other mobile platforms including Android and iOS in the future to form a universal platform for all mobile virtual financial transactions. By then, I'm afraid its influence will be unpredictable.

Sirin raised $158 million through an ICO in December last year after receiving $70 million in investment. Its blockchain mobile phone products are expected to start shipping in October this year. Sirin is expected to be sold in the most active cryptocurrency regions including Vietnam and Turkey. The company also hopes to sell the phone through mobile carriers and said 25,000 people have ordered the phone so far and plans to ship 100,000 to millions of units this year.

Many people around the world have bought Bitcoin, but few people use it in daily transactions. To prevent theft, users need to store their money in a dedicated storage device and remember their username and long password. This phone may change that and make the use of cryptocurrencies more widespread.

Digital丨Finney Blockchain Smartphone

Moshe Hogeg, executive director of Sirin, said in an interview: "Based on the existing user experience, the mass market is not yet up to this kind of service. My mother is very smart, but she did not have the opportunity to understand how to use Bitcoin."

According to Introduction, this phone can use various tokens. Users can shop at currency-supported stores like Overstock.com and Expedia and exchange cash for specific tokens when necessary. Additionally, users can earn cryptocurrency rewards by activating mobile Wi-Fi and sharing Wi-Fi hotspots.

Security design is also one of its highlights: Finney’s mobile phone can be activated through a physical switch to handle money-related services. Users do not need to enter complex addresses and private keys, but only need to scan iris, fingerprint andA simple password can prove your identity.

However, some people hold different opinions. Matt Suiche, founder of cybersecurity firm Comae Technologies, believes that even though this phone architecture appears to be secure, there is a danger that thieves will violently coerce Fenni users to obtain their wallets.

As for the cooperation with Foxconn, Sirin Expressed hope to license other phone manufacturers to use their technology, thereby reducing the price of Fenni from $1,000 to $200.

Can Sirin currently Turning the phone into a blockbuster product remains unclear, but some of Hogeg's early investors aren't giving up. It will definitely be difficult for Finney to really seize the mobile phone market, but Hogeg seems to be confident: "I want to do something to improve the user experience. Look at the Great Wall of China. At the beginning, one person laid a brick, and then he continued to lay bricks. We can also step by step One step at a time."

So, what does this cooperation mean for another key player in this incident, Foxconn, which has built a Great Wall in mobile phone manufacturing?

Hon Hai’s strategy is actually very simple, because it is engaged in mobile phone manufacturing .

For so many years, I have always wanted to be close to the market and front-line consumers. Therefore, in the past few years, Hon Hai's so-called "cloud-moving things and big intelligence network" strategy, as well as the "front store and back factory" concept once proposed by Hon Hai Chairman Terry Gou, are actually hoping to better understand customers. Because Hon Hai has many customers, such as companies like Apple, Amazon, and Cisco, Hon Hai’s relationship with these customers is no longer simply about helping them make products, but also includes helping these customers think about what products they want to make.

This is also the only way for Hon Hai to understand consumers better. In addition, Hon Hai is also trying to establish its own brand. In the past few years, Hon Hai has actually been We are making similar attempts, whether it is investing in Sharp or the recent purchase of Belkin.

The main purpose of acquiring Belkin is actually its strong sales channels.Tao, as well as global brand recognition, coupled with more than 700 patents, it can play a great role whether as a smart home product itself or to assist future private brand sales.

Hon Hai's cooperation with Sirin this time is not just an attempt, but can also be regarded as a link in Hon Hai's overall strategic layout. It combines its own smart terminal products such as TVs and home appliances with the layout of mobile phone products, as well as more mature Channel management, after introducing the blockchain ecosystem, from terminal to cloud to transaction cash flow, can more thoroughly establish its own business model. Moreover, Hon Hai has its own operator Asia Pacific Telecom in Taiwan. The existence of Asia Pacific Telecom allows Hon Hai to test many different possibilities of terminal devices.

So it is indeed very reasonable for Hon Hai to cooperate with Sirin. But this cooperation may not necessarily be a large-scale investment. After all, the other party only authorized it to produce this mobile phone. Whether this mobile phone will eventually be sold in large quantities is just a test of the market temperature. It is difficult to draw a conclusion now. .

At the end of March this year, Lenovo released its first blockchain phone, the S5. According to reports, this phone only uses blockchain technology for encrypted and secure payments. Also in March, Changhong also launched the R8 Kirin, a mobile phone equipped with blockchain technology.

Picture丨Lenovo S5

The focus of the blockchain phone is not the mobile phone but the blockchain. As it stands, the phone is designed to store cryptocurrency with the highest security, and supports peer-to-peer payments and communication encryption. Of course, mobile phone manufacturers can also allow users to mine their own cryptocurrencies, but this means they need to build their own platform. The main users of blockchain mobile phones are undoubtedly those who are enthusiasts of cryptocurrency. They have a lot of interest in the spread of blockchain products and subsequent services derived from blockchain technology, and will actively invest in them.

These manufacturers all claim to launch blockchain mobile phones. So, how big will the market be for a mobile phone that claims to be related to blockchain? One possibility is that blockchain mobile phones integrate the wallet functions of mainstream cryptocurrencies. This development idea can guide customer needs. If the product design is reasonable, it may indeed evolve into actual needs. After all, many blockchain technologies are now beginning to develop uses beyond cryptocurrency, and even derive ecosystems, which may be used by ordinary consumers in the future.

In addition to some manufacturers who have confirmed that they will produce blockchain mobile phones, Huawei has previously reported that it intends to cooperate with Sirin Labs to jointly develop blockchain apps that can run on the Android system. However, this rumor has not been confirmed by Huawei. confirm. Xiaomi and Smartisan have recently begun recruiting senior blockchain engineers, which also leaves a lot of room for imagination.

The booming development of blockchain mobile phones is more likely to be an important driver of pushing cryptocurrency into mainstream status. The current transaction procedures of cryptocurrency are too complicated, making it difficult to truly spread into ordinary life. If through Sirin DistrictWith the help of blockchain mobile phones, cryptocurrency can accelerate its penetration into daily transactions, which will further increase the breadth and popularity of the entire blockchain transaction and accelerate the promotion of cryptocurrency to become a part of regular currency, rather than just existing in the hype market. .

Just a few months ago, blockchain phones were considered a joke by many people, but now it seems that we are just around the corner to use blockchain phones.

Related questions and answers: Characteristics of blockchain technology The five basic characteristics of blockchain technology are as follows: 1. Characteristics of blockchain technology 1: Distributed database Each party on the blockchain can access the entire database and its complete historical records. No single party controls the data or information. Each party can directly verify the records of its trading partners without the need for a middleman. 2. Blockchain technology feature 2: Peer-to-peer transmission communication occurs directly between peers rather than through a central node. Each node stores and forwards information to all other nodes. 3. Blockchain technology feature three: Transparent anonymity. Any user with access to the system can see each transaction and its associated value. Each node or user on the blockchain has a unique address consisting of more than 30 letters and numbers, which is used to identify itself. Users can choose to remain anonymous or provide proof of their identity to others. The addition of the blockchain occurs at one of these addresses. 4. Blockchain technology feature four: Irreversibility of records Once a transaction is entered in the database and an account is updated, the records cannot be changed because they are linked to every transaction record before them (hence the name "chain"). Various algorithms are employed to ensure that records in the database are permanent, chronologically ordered, and accessible to all other nodes on the network. 5. Blockchain technology feature 5: The digital nature of the computational logic ledger means that blockchain transactions can be associated with computational logic and are essentially programmable. Therefore, users can set algorithms and rules that automatically trigger transactions between nodes. Expanded information: Blockchain is a chain composed of blocks one after another. Each block stores a certain amount of information, and they are connected into a chain in the order in which they were generated. This chain is saved in all servers. As long as one server in the entire system can work, the entire blockchain is safe. These servers are called nodes in the blockchain system, and they provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes. These nodes are usually in the hands of different subjects, so it is extremely difficult to tamper with the information in the blockchain. thing. Compared with traditional networks, blockchain has two core characteristics: data is difficult to tamper with and decentralized. Based on these two characteristics, the information recorded in the blockchain is more authentic and reliable, and can help solve the problem of people's mutual distrust.
