Blockchain, which has been busy for four months, is hot almost at the first touch. From the capital craze to we media cluster, now hardware manufacturers are also planning to take a share
as of April 12, Lenovo's block chain mobile phone S5 has been on sale for about 20 days. This thousand yuan machine mainly uses "blockchain" protection technology to ensure payment security< in addition to Lenovo S5, candy S11 and Changhong R8 Qilin also label blockchain mobile phones, and claim to have blockchain wallet, mobile phone mining and other functions
in the view of a number of technicians and instry insiders in the blockchain instry, the above-mentioned blockchain concept mobile phone does not make clear what specific blockchain technology is applied. The so-called encryption function is vague, and its technology is also applied in ordinary mobile phones. However, because the computing power of mobile phones is completely difficult to compete with mining machines, "mobile phone mining" is not realistic
however, it is not impossible for blockchain to be applied to smart hardware such as mobile phones“ If it is clear how to integrate the blockchain into the hardware, how many nodes there are, and what consensus mechanism and encryption means are used, the public will be more convinced. " Cao Yin said
Zhao Yongliang, vice president of Shandong blockchain Application Technology Research Institute, analyzed that after the development of smart phones in recent years, they have encountered a bottleneck. For some non head traditional manufacturers, there is no new growth and innovation, "in this respect, blockchain mobile phones are more like a gimmick."
3. The encryption of jinwowo blockchain can ensure that the privacy of data sources can be better protected when big data is called, so as to eliminate the bad phenomenon of reselling data.
4. Homomorphic encryption is a special encryption method. The result of special operation after plaintext encryption is the same as that of encryption after plaintext special processing. This technology can perform such operations as retrieval and comparison in encrypted data without decrypting the data first, which fundamentally solves the problem of confidentiality when entrusting the data to a third party. This kind of professional terms are very abstruse on the Internet. It's hard to understand without foundation. I recommend you to see the official website of Xuanling technology. The above blockchain professional terms are quite popular. If you don't understand, you can also contact customer service on the website and ask them to answer.
5. The English full name of alot is "artificial intelligence & Internet of things". Broadly speaking, it refers to the integration of artificial intelligence technology and Internet of things in practical application. However, with the arrival of 5g wave, the connotation of "alot" has become increasingly rich. Aiot is not a simple AI + IOT, but the application of artificial intelligence, Internet of things and other technologies, based on big data and cloud computing, with semiconctor as the algorithm carrier, with network security technology as the implementation guarantee, with 5g as the catalyst, to integrate data, knowledge and intelligence
5g, AI and other emerging technologies will fully break out in 2019, enabling more and more application scenarios such as autonomous driving, urban brain, AI pension, medical imaging to step down from the "altar" and enter our lives. 5g has the characteristics of high speed, large capacity and low delay, which brings more efficient information transmission channel for IOT. It has broad prospects in smart home, Internet of vehicles, driverless, smart city, smart medical care, smart countryside and other fields. The blessing of AI technology provides IOT with a more intelligent information collection portal and richer application scenarios. AI can bring a relatively isolated device into the scene, which can greatly improve the response space of IOT.

stamp ty - 0.1%
land transfer fee: the current year's cost price multiplied by the building area multiplied by 1%
if it is a housing reform house with standard price or preferential price, it is necessary to pay the price of the current year's cost price multiplied by the building area multiplied by 6%, and then pay the tax to transfer the ownership<
