Jinbodi company transferred to blockchain
Recently, a blockchain recruitment advertisement in Beijing has burst the circle of friends, requiring candidates to have in-depth research on blockchain technology and cryptography, and the annual salary given is not less than 5 million yuan, and there is no ceiling
Song Mofei told reporters that in the actual development process, it is far from enough to simply master the use of some blockchain tools. Because there are still many problems in the efficiency and scalability of blockchain, developers need to improve the underlying platform of blockchain to meet the needs of practical application. The blockchain technology is a typical composite comprehensive discipline, which integrates cryptography, computer network and game theory. It is not easy to master and understand the underlying technology of blockchain overnightaccording to Shan Yi, chief data officer of liepin.com, the core of blockchain is the change of social relations and business model based on Internet distributed trust system, which is characterized by decentralization“ There are still many uncertainties in the future development of block chain. There are obvious bubbles at present, and many block chain projects are not reliable. He said
development status of big data instry. Now these data are not only huge, but also shared on the Internet. In the face of all Internet users, the number is unprecedented
2. After the emergence of mobile Internet, many sensors of mobile devices collected a large amount of user click behavior data. It is known that iPhone has three sensors and Samsung has six sensors. They generate a large amount of click data every day, which is owned by some companies, forming a large amount of user behavior data
3. After the appearance of electronic maps such as Gaode, Internet and Google maps, a large number of data streams have been generated, which are different from traditional data. Traditional data represents an attribute or a measure, but the stream data generated by these maps represents a kind of behavior and a habit, and these stream data will have great commercial value after frequency analysis. Map based data stream is a new type of data, which did not exist in the past
4. After entering the era of social network, Internet behavior is mainly created by users, and a large number of Internet users create a large amount of social behavior data, which has never appeared in the past. It reveals the characteristics of people's behavior and living habits
5. The rise of e-commerce has proced a large number of online transaction data, including payment data, query behavior, logistics transportation, purchase preference, click order, evaluation behavior, etc., which are information flow and capital flow data
6. After the traditional Internet entrance turned to search engine, users' search behavior and questioning behavior gathered massive data. The decline of unit storage price also provides economic possibility for storing these data
the simultaneous interpreting of large data and traditional data is different from traditional data. Big data is closer to a group behavior data, it is comprehensive data, accurate data, valuable data
China has a long way to go on the road of big data
compared with the United States, China's current big data application environment and technology differ in the overall technical level, application environment, national consciousness, business environment, technology manufacturers and technology platform for more than five years. At the national strategic level of big data application, there are also many laggards
In March 2012, the Obama administration announced the launch of "big data research and development plan". The program involves six federal government departments, including the National Science Foundation of the United States, the National Institutes of health, the Department of energy, the Department of defense, the advanced research projects agency of the Department of defense, and the U.S. Geological Survey. It is committed to invest more than 200 million US dollars to vigorously promote and improve the collection, organization, and analysis tools and technologies related to big data, so as to promote the development of large-scale data collection, organization, and analysis The ability to acquire knowledge and insight from complex data sets. The announcement by the Obama administration of the United States to invest in big data is a watershed for big data to rise from business behavior to national strategy, which indicates that big data has been officially promoted to the strategic level, and big data has begun to be valued in all levels and fields of economy and society2014, from the proposal and motion of the NPC and CPPCC, many people suggested that the big data business should be promoted to national strategy. Robin Li, the Internet leader, said at the CPPCC press conference that the government should put more data related to people's lives on the Internet. Lei Jun directly suggested that big data should be included in the national strategy to promote the practical use of big data; IFLYTEK Liu Qingfeng suggested that the state build voiceprint database for big data anti-terrorism. The proposals of Zhang Jindong, Ma Huateng and Yang Yuanqing are also closely related to data application. However, there is no clear blueprint for China's big data national strategy and the development of big data instry
in conclusion, the era of big data will bring great changes to human society. It is a good tool, just like the computer, to help people improve social proction efficiency, understand the truth of things, understand the objective laws, and speed up the entry into the intelligent society
