In less than three months since the beginning of 2018, three blockchain mobile phones have emerged in the Chinese market: Candy "Creation Edition" mobile phone was released on January 11, Changhong R8 Kirin mobile phone was unveiled on March 13, and 3 Lenovo launched S5 on March 20th. Objectively speaking, if these three mobile phones compete purely based on software and hardware configurations, they will not be able to make waves in today's "sea of machines" with serious homogeneity. But what is incredible is that just because they all use the concept of blockchain, there is a widespread phenomenon of premium prices. For example, the candy "Creation Edition" mobile phone that only uses a thousand-yuan processor configuration sells for as high as 3,999 yuan!

The enthusiastic response from the market suddenly aroused the enthusiasm of mobile phone manufacturers, and blockchain mobile phones have also become a new commanding height. But what exactly is a blockchain phone? Are the currently released blockchain phones a gimmick or a real innovation? To this end, a reporter from the People’s Post and Telecommunications exclusively interviewed an Internet technology expert and cloud computing expert from the China Academy of Information and Communications Technology and He Baohong, deputy director of the Big Data Research Institute, asked him to clear up the fog currently shrouding blockchain mobile phones.

Question: Can blockchain mobile phones really “mine”? 

The first Candy Genesis mobile phone released was developed by Candy Mobile in conjunction with the Ethereum Fog Foundation, and is claimed to be capable of “mobile mining.”

Regarding "mobile mining", the official description of Candy Mobile is as follows: The current mining mechanism of Candy Points does not require any additional operations to obtain Candy Points regularly (i.e. "Mobile Mining"). In the future, the Ethereum Fog Blockchain Network (ETF ) will add a POC storage space mining mechanism. Candy blockchain mobile phones can install SD cards or external mobile hard drives to perform POC mining. Mobile phone users upload shared storage space to all network users, and they can mine ETFs and exchange them for candy points. Candy points are a points system that uses blockchain technology.

Obviously, the Candy blockchain phone cannot really be used for "mining" at present, because it cannot mine virtual currency at all, but can only help users "mine points". The conceptual hype is far greater than the actual value.

In fact, the feasibility of mobile phone “mining” is not high. He Baohong emphasized that the blockchain itself is a high-density computing technology, so if you want to use a mobile phone to "mine", the mobile phone will not be able to support it in terms of computing power or electricity. He Baohong also specifically gave a number. At present, the size of the complete Bitcoin public ledger has exceeded 150GB, which is simply not supported by terminals such as mobile phones.

Second question: Are blockchain phones safer? 

Unlike candy phones that sell dog meat at the expense of others, Changhong R8 Kirin mobile phones and Lenovo S5 play a "safety card."

Changhong R8 Kirin mobile phone is launched by Changhong and Unicorn China Community. Through the innovative combination of software and hardware technology, it strengthens the security of mobile phone blockchain applications and reduces transaction information congestion. It is worth noting that Unicorn is positioned as a secure, distributed mobile trust network infrastructure that combines device fingerprint verification technology and location-based service technology.

Lenovo S5 uses blockchain technology to make payments more secure. In this regard, Chang Cheng, Vice President of Lenovo Group, said that S5 plays an important role in the encrypted secure payment space - Z
The space payment area system applies "blockchain" technology to the bottom layer, which can make payments safer. But he did not reveal more specific technical details.

Objectively speaking, the natural characteristics of blockchain that can prevent tampering make it promising in the field of security. Therefore, it seems more reliable to choose Changhong and Lenovo, which start from the security field. However, Lenovo’s secretive approach still makes the industry suspect that it is just using the concept of blockchain as a gimmick.

However, looking forward to the future application of blockchain on mobile phones, it is foreseeable that security applications will be the first to come true. He Baohong pointed out that the blockchain application that may appear on mobile phones in the future may be a virtual currency wallet. Such applications can take advantage of the blockchain's advantages in secure accounting and provide services to users in the form of Apps. It is worth noting that from a technical point of view, the nodes of the blockchain are actually on the Internet, and users only use Access via mobile phone.

To sum up, the current blockchain mobile phones that have successfully attracted attention are mostly just gimmicks. However, today, when the growth rate of smartphones is slowing down and homogeneous competition is serious, blockchain mobile phones have successfully opened up a new and differentiated market segment, and blockchain mobile phones that are truly worthy of the name are also worthy of the industry's expectations!
