On March 20th, Lenovo Group, who had not spoken for a long time, introduced three new models at a stretch. One of the Lenovo S5s was also tagged with a blockchain.
The keynote speaker of the conference, Lenovo Group Vice President Chang Cheng, stated that S5 used the 'blockchain' technology at the bottom of the cryptographic secure payment space, the Z-space payment area system, to make payment more secure. As for the specific Technical details, the process did not disclose more.
When interviewed by Lenovo’s news reporters, Lenovo’s mobile phone related parties also rehearbed the above-mentioned functions. As for how blockchain technology can be used on S5, users can use this blockchain technology to achieve what they can achieve. The person said that these are temporary Information, if there is further information to communicate later.
Unlike Lenovo, the blockchain mobile phones launched by the other two mobile phone companies seem to be able to catch up with the "chain mining" of the blockchain.
In January of this year, SUGAR Candy Mobile announced its strategic cooperation with the Ether Fog Foundation (ETF) and released the world's first blockchain mobile phone - Candy's "Genesis" blockchain phone.
According to the external promotion of the candy mobile phone, the mobile phone uses the Ether blockchain technology, the mobile phone collects the block chain wallet and the blockchain miner, priced at 3999 yuan.
The official stated that the candy blockchain mobile phone is based on the blockchain technology used in the 'Candy Points' program. The mining mechanism does not require the installation of a full node to 'mine', and it regularly obtains candy points. After the POC algorithm has been upgraded during the later period, The external mobile hard disk can be upgraded to full node for storage and mining. From this expression, after the candy mobile phone is bought back, each mobile phone user can “mine” and earn “confectionery points”.
According to the official explanation of candy, 'Candy Points' can be exchanged for goods and services specified in the physical candy store and application market, such as the next generation of candy blockchain mobile phones, mobile phone protection cases, candy payment APP, after-sales service, spokesperson fan meeting tickets, etc. .
On March 16th, Changhong also launched the blockchain mobile phone R8 Unicorn, also claiming to be the world's first blockchain mobile phone. The starting price of the mobile phone is 2999 yuan.
Changhong Chairman Guo Dexuan disclosed, 'This is the first mobile phone developed by Unicom for Unicorn to carry the Unicorn blockchain mobile phone.' Its POW-based consensus algorithm, device fingerprinting technology, and LBS location service, are roughly: Users can use Changhong Mobile to dig Mine, and use blockchain to record fingerprints and geographical location information.
The principle of blockchain is to decentralize, reduce hierarchy, and information flow exists on each computing node. Changhong Unicorn technology uses a Bitcoin-like algorithm. The mobile phone is used as a computing node to perform operations directly, and the data is stored on the mobile phone. It is decentralized, decentralized, and information will not be tampered with.
However, the mining of a small cell phone terminal may not be the same thing as the professional understanding of the 'miner'.
Lu Tianwen, secretary-general of the Energy Conservation Technical Committee of the China Electronic Energy-saving Technology Association, told reporters in an interview that it is impossible for users to participate in digging 'bitcoin'. It is impossible for mobile companies to dig their own virtual Currency. 'This means that mobile phone companies need to build their own platforms, use their blockchain principles to bring their users together to 'mines', giving users some small benefits like points redemption.
Many people in the mobile phone industry accepted the interview with reporters during the interview. They all said that it is not clear what the blockchain phone is and what its functions are. The general conclusions are 'Shantou,' 'hype,' and 'hot spot'.
Lu Tianwen also directly categorizes the current blockchain mobile phone as a gimmick. 'Now, the blockchain technology has no practical use. It only uses the psychology of people's lottery, and the technology is structured to be used on mobile phones. . '
According to Lu Tianwen, the essence of blockchain is decentralization, reducing tiers, and making storage more secure. However, from a professional perspective, blockchain mobile phones have not been more secure. 'A mobile phone took 2-3 years. Even if a computer is used for a maximum of five years, or if the mobile phone or computer suddenly fails during use, this poses a big security risk. Both the hardware and software security are not discussed. It starts directly from the application. This is a big problem. In addition, some people play the concept of blockchain, not even a single platform, let alone practical application.
Lu Tianwen's point is that blockchain technology can actually help reduce investment and reduce costs for SMEs, but it can only be used in some non-critical areas, and some key areas cannot use blockchain technology.
