Chengdu 2020 coin printing blockchain Summit
Because the blockchain technology is not mature at this stage, and the infrastructure is not perfect, many applications are limited, and the overall application is still in a very early stage
First of all, the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database. Secondly, anyone can set up a server and join the blockchain network to become a node. In the world of blockchain, there is no central node (decentralization). Every node is equal and keeps the whole database. You can write / read data to any node, because all nodes will be synchronized in the end to ensure the consistency of the blockchainTraceability is one of the important application scenarios of blockchain technology. For consumers, food safety is a matter of life and health, so we now have higher and higher requirements for the quality of food. Due to its non tamperability, blockchain technology can record the whole life cycle process of food in the whole process, which can make us eat more at ease

the predecessor of School of Geology and exploration engineering of Xinjiang University is a teaching and research group of metal Department of Sino Soviet School of mining technology established in 1953. The teaching and research group was changed to geology department when Urumqi mining school was established in 1955, and to mining department when Xinjiang mining and Metallurgy College was established in 1958. In September 1979, two undergraate majors, mining and mining machinery, were abolished. After the geology major was left, the Department of mining was renamed the Department of geology. In 1998, it was renamed the Department of resources and environmental engineering of Xinjiang Institute of Technology (hereinafter referred to as the former Department of geology of Xinjiang Institute of Technology). The development of the College of Geology and exploration engineering of Xinjiang university can be divided into three stages: ① the former Department of geology of Xinjiang Institute of Technology (1953-2000); ② School of resources and Environmental Sciences of Xinjiang University after the merger of former Xinjiang Institute of technology and former Xinjiang University (from 2000 to January 2008); ③ College of Geology and exploration engineering, Xinjiang University (January 2008 to present). The first section is the evolution of the College of Geology and exploration engineering. The Department of resource and environmental engineering of the former Institute of technology is the same age as the former Xinjiang Institute of technology, and has gone through several merging processes. The Department of resources and environmental engineering was first established as a teaching and research group of the metals department of the mining technology school jointly run by China and the Soviet Union in 1953. It was the Geology Department of Urumqi mining school in 1955. In 1958, the "technical school" was renamed as "Xinjiang Institute of mining and metallurgy". Based on the specialty of "metal mineral and petroleum geological exploration", the Department of mining was established. The key teachers are: Li yaozeng, Zhu Xingnan, Wang Gongke Xu Zhongping, Zhang Xidong, etc. Two majors of "metal mineral and petroleum geological exploration" were set up, and "707 geological team" was set up at the same time, which led to the teaching road of combining theory with practice. Mine geology, regional geological survey and mineral general survey were carried out. In 1958, it began to recruit undergraates. In 1966, the "Xinjiang Institute of mining and metallurgy" was renamed as "Xinjiang Institute of technology". The original Department of geology was changed into the Department of mining, under which there are two majors: Mineral Survey and exploration and underground mining of metal minerals. In 1981, the major of underground mining of metallic minerals was abolished, and the Department of mining was changed to the Department of geology again, and the major of mineral survey and exploration was still set up. With the reform and opening up and the demand for talents in Xinjiang, in 1998, with the approval of the Ecation Committee of Xinjiang Autonomous Region, the original Department of geology was changed to the Department of resources and environmental engineering, with three specialties: resources exploration engineering and Technology (mineral survey and Exploration), resources exploration technology and Engineering (hydrological and Geological Engineering) and environmental geological engineering and technology. In 1978, the subject "mineral survey and exploration" was the first master program approved by the state in Xinjiang. Today's College of Geology and exploration engineering has gone through three stages of development: the Department of geology of the former Xinjiang Institute of Technology (1953-2000), the College of resources and Environmental Sciences of Xinjiang University (2000-2008) after the merger of the former Xinjiang Institute of technology and the former Xinjiang University, and the College of geology and exploration engineering of Xinjiang University (2008-now), It has become an important base for professional ecation, high-level personnel training and scientific research in the field of resource exploration and Engineering Science in Xinjiang. In teaching, it has formed a relatively complete training system for undergraates and postgraates. In teaching and scientific research, they undertake different teaching and research tasks, and have basic teaching laboratories with complete equipment. We have trained and formed a reasonable number of academic leaders and young teachers with high ecation level, which has laid a solid foundation for the cultivation of talents in the field of geological resources and geological engineering. He has made outstanding achievements in personnel training. Led by the late Professor Li yaozeng, he has trained more than 1000 undergraate professionals and more than 200 master professionals, including academician Jia Chengzao, academician of Chinese Academy of Sciences and vice president of PetroChina. He has made certain contributions to the economic construction of the autonomous region and the country. At present, the College of Geology and exploration engineering has a strong comprehensive strength in the field of geological resources and geological engineering, and will create a brilliant future in the new century. The second section is the general situation of the college. The College of Geology and exploration engineering of Xinjiang University is the earliest teaching and scientific research institution in Colleges and universities in China. At present, the teaching specialties of the college include: resource exploration engineering, exploration technology and engineering, and mining engineering; There are three master's degree awarding points: "mineral survey and exploration", "Earth exploration and information technology", "mineralogy, petrology and deposit science". It has a relatively complete undergraate and postgraate training system from bachelor's degree to master's degree. At present, there are 33 teaching staff in the hospital, including 5 professors, 14 associate professors, 9 lecturers, 9 doctoral degree teachers (the other 4 are studying), and 7 master's degree teachers. There are 417 undergraate students, 58 master students and 5 postdoctoral project researchers in the "geological and mineral research direction" of Xinjiang University. The College of Geology and exploration engineering has formed a new system of teaching and scientific research. At present, there are basic geology teaching and research section, resource exploration teaching and research section, exploration technology and engineering teaching and research section and mining engineering teaching and research section. The college has nearly ten million yuan worth of scientific research and teaching equipment, good infrastructure, complete laboratory construction, which provides good conditions for teaching and scientific research. Since the College of Geology and exploration engineering was separated from the College of resources and Environmental Sciences in January 2008 and established a new college, the college reference room is still under construction. At present, there are more than 5000 books and periodicals in Chinese and foreign languages. In 2003, the subject of "mineral survey and exploration" was listed as the key subject of the autonomous region; At the same time was included in our school & quot; 211 Project & quot; Focus on the construction of disciplines. Since then, the autonomous region and the school have invested in discipline construction funds every year, and the discipline has entered a period of leapfrog development. There are three main research directions: (1) Central Asian orogeny and mineralization 2) Identification and prediction of large ore concentration area 3) Application of "3S" and multi-source information synthesis technology in geological prospecting. In recent five years, Professor Zhang Xiaofan, Professor Sun Baosheng and others have undertaken the national key basic research project "973" sub project, and 9 scientific research projects above the provincial and ministerial level, such as the projects supported by the Ministry of science and technology. In the past five years, it has undertaken 53 vertical and horizontal projects at all levels, with a total fund of 15.8379 million yuan; Published 27 high-quality papers in core journals at home and abroad, 4 of which were included in SCI, 1 in EI and 2 in ISTP. In the past five years, a series of research achievements have been made in the fields of identification and prediction of large-scale ore concentration areas, application of "3S" and multi-source information comprehensive technology in geological prospecting, among which, three second and one third prizes have been awarded for excellent academic papers in natural sciences of the Autonomous Region, and one third prize for excellent academic papers in natural sciences of Urumqi, Xinjiang University Natural Science Achievement special prize once. Won the third prize of excellent teaching achievement in the autonomous region once; In the evaluation of excellent teaching achievements of Xinjiang University, he won two special prizes and one second prize. One monograph and one college characteristic textbook were published. The college always takes "ecation should face modernization, the future and the world" as the guiding ideology, earnestly implements the party's ecational policy, takes "seeking truth, striving, unity and innovation" as the ecational philosophy, and takes cultivating qualified talents with good moral quality and comprehensive quality as its own responsibility. Over the past few years, the college has always focused on the identification and prediction of large ore concentration areas in Xinjiang and Central Asia, contributing to the economic construction of Xinjiang and the scientific implementation of the western development strategy.
