What are the blockchain tokens of the Internet of things
zilliqa project's token name is ZIL, which has been circulated and traded on 23 exchanges. Mainstream exchanges such as fire coin and coin an support it, so it is very convenient to participate. ZIL's maximum supply is 21 billion, of which 12.6 billion will be released directly through contracts, and the other 8.4 billion will be released in the form of mining awards within 10 years
the main network of zilliqa will be launched at the end of 2018 or the beginning of 2019, and the mining reward is rich, especially in the early stage. The electric power cost of zilliqa mining is only 1 / 9 of that of Ethereum, so it is more feasible with less energy consumption. In addition, mining can be carried out through GPU graphics card miner, and can simultaneously double dig ZIL and eth, bringing higher benefits for miners

1. What is the Internet of things
in fact, in a simple way, big data is to assist decision-making by analyzing and mining a full amount of non sampling data
the characteristics of big data
big data refers to the massive, high growth rate and diversified information capital that needs new data processing mode to collect, store, manage and analyze its content for the purpose of serving decision-making
big data has the following essential characteristics:
1. The fundamental purpose is to serve decision-making. Big data can help all kinds of organizations and indivials greatly improve their decision-making ability and make better decisions and judgments
Big data usually refers to the amount of data above 100t, which is difficult to be calculated effectively by traditional calculation methods, but must rely on new calculation methods and data mining tools3. High frequency, big data is the data generated by user participation and interaction, according to the user's network traces to timely understand the user's relevant data, this kind of data is high-frequency data calculated by day or even hour. But the traditional data frequency is very low, many data are calculated by month or even by year
Big data is real-time data and can react in real time. For example, entering a keyword in the web search box can instantly present it, while the traditional data collection method is seriously lagging behind5. Always online. Online is the precondition of big data. From this point of view, big data is always online and can be called at any time. By analyzing the traces of users on various network terminals, big data can better analyze users' behaviors, emotions, thoughts, hobbies and needs, so as to make better decisions and analysis
three key points of big data
first, the availability of data. At present, in China, the development of big data is seriously constrained by the lack of publicity of government information, a lot of data is difficult to obtain, leading to the difficulty of real big data mining and analysis, which requires the government to open more data in time to improve the availability of data
Secondly, the scientific model construction. The scientific nature of the model directly determines the quality of data analysis, which requires a high level of modeling, of course, the more data is concive to the reasonable construction of the modelThird, use experts to refine opinions. The original and high-quality viewpoint based on data mining, which provides the basis for decision-making, highly relies on high-quality data interpretation, which reflects the value of instry experts
provided by IOT media
in the near future, the number of devices in the Internet of things will explode, which may be hundreds of billions or trillions. If such a huge network is still managed in a centralized networking mode, the infrastructure investment and maintenance of the data center should be incalculable
in essence, big data belongs to a small branch of database, so this problem is attributed to the relationship between big data and database. Database is a very old research field in software, Internet and it. From the initial file system to ER model, to the three achievements of traditional database, which are known to all, relational model, transaction processing and query optimization, to the rise of NoSQL database after the popularity of Internet, database technology is constantly developing and changing, Then it also includes semi-structured data processing represented by XML and unstructured data processing such as text and voice
it seems that the relationship between blockchain and database is actually such a relationship. From the evolution process of database technology, we can find that it always comes from how to meet new business requirements and then create new data processing technologies. For example, from the beginning of the file system, why do we need the ER model? It is because with the development of the financial instry, people have further requirements for these fast accounting, high concurrency data writing and access, which leads to the emergence and rapid development of the entity relationship model. Why did NoSQL database appear later? It is because the rapid development of the Internet puts forward higher requirements for updating the database, so in essence we think that the whole Internet is a big database
things are always developing. Of course, after we solve the problem of massive real-time data processing on the Internet through NoSQL database and cloud storage, the next problem must come, that is, how to solve the authenticity and effectiveness of data in a large-scale way
for example, it may be related to our diet, from the problem of food and clothing at the beginning, to the problem of nutrition structure, and then to the problem of food safety that everyone is concerned about. The development of database is the same. When we can solve these problems of data storage and data access through ER entity relationship model and NoSQL database, Next, we need to care about and solve the problem of authenticity and effectiveness
so at this stage, these technologies, represented by blockchain, must be a new starting point and new requirements for the authenticity, validity, unforgeability and tamper resistance of data compared with the current database. We can clearly feel that the trend of database and blockchain integration is actually very close and irresistible, just like the movie just mentioned, the procers of content begin to develop in the direction of virtual reality and augmented reality; From the perspective of database, blockchain is a new way of data organization. We believe that big data and blockchain are integrated.
the term "Internet of things" is mentioned almost every day in today's life. Some data show that in 2017, there were about 8.4 billion intelligent devices connected to the Internet, such as thermostats, cameras, street lamps and other electronic procts. According to foreign McKinsey & company data, this number may reach 25 billion by 2025, and the scale of the whole economy will reach 6 trillion US dollars
are you dazzled by such a huge number? Although the Internet of things technology has been widely used all over the world, its defects are graally highlighted
according to the traditional mode, the data center (server) of the equipment manufacturer often collects the information of all connected devices, which determines that the server needs to have strong operation and storage capacity. Moreover, with the geometric growth of Internet of things equipment, the cost of server maintenance will also increase greatly, which makes it difficult for small and medium-sized enterprises to maintain
at the same time, in terms of communication compatibility, the global Internet of things platforms are lack of a unified language, which is easy to cause communication obstacles between multiple Internet of things devices. This is e to the obvious fragmentation of the Internet of things instry, whether it is smart home, smart home appliances, robots, smart cars, etc., the networks they connect are fragmented and closed. In addition, the status quo of the Internet of things instry is still full of mountains, and their influence is relatively limited, so it is difficult to reach a unified standard in a short time
based on this, the standard chain team, after accumulating the previous experience from the Internet of things, combined with the characteristics of blockchain, proposed the concept of Internet of things

Of course it's fake < H2 > [alert! According to Caixin, the digital bill trading platform based on blockchain promoted by the central bank has been successfully tested, and the legal digital currency issued by the central bank has been put into trial operation on the platform, and the research and development center will continue to improve in the near future; After the Spring Festival, the digital currency Research Institute of the central bank will also be officially listed. This means that in the world, the Central Bank of China will become the first central bank to issue digital currency and carry out real application, and take the lead in exploring the practical application of blockchain. The implementation of the project is a major financial technology achievement led by the central bank and independently innovated and developed. This shows that the people's Bank of China is closely following the international frontier trend of financial technology, striving to grasp the foresight and control of the application of financial technology, and its determination and efforts to explore and practice frontier financial services. The people's Bank of China has said that it will publish digital currency R & D talents on the official Internet, which is of great importance. Here I would like to remind you that the more formal and professional new things are, the more professional talents must be given to operate them

for example, Internet of things digital currency / national cause (charity) wechat group fraud backbone [Wang Sulan], [Cai Yongming], [Xue gendi], [Du Kaiju], [Liu Yanfei], [Wang Hongjun] Ju Fang, Tian Genmin, Li qiuqiong, Fu Yunjuan, sun Qing, Wang Yanyan, Qu Fengtao, Li MEIXIA, Wu Juzhen, Lin Baihe, Li Jianhua, Xu Tao, Li Yingchun, etc. created a learning group from Lei Feng, precision poverty alleviation group, b33651 group, Wang Sulan, Cai Yongming new project report group, Shanghai learning group Lei Feng core group, Shanghai xuegendi team, learning group, positive energy 605, charity 128-1, charity love harmony 87, Internet of things 133-9, China physical network digital currency, 68 District of Third Bureau, Qian Shuai 16, independent special zone of Internet of things, Li Jianhua, digital currency of China Internet of things Three groups, such as [Lin Baihe ~ China Internet of things digital currency group], [AQR Daqin Financial Holdings] (in order to avoid the attack of network security, change the group name from time to time), and so on. These fraud groups are advocating various high return projects under the guise of patriotism ([Cai Baiping investment bank project], [169 yuan project], [958 group benefiting the country and the people project (charity enriching Chen Yuying team project)], [charity enriching the people (958 group 51 single) project table 22 yuan, supplementary payment 20 yuan], [2 Yuan Li Yunlong (love) China Chen Yuying foundation project], [10 yuan silver fund fee - 958 group], [Ministry of finance project charity enriching the people Chen Yuying team (100 yuan) project] [18 new projects E-form charity enriching Chen Yuying team on April 9, 2017], [Chen Yuying 200000 Lika project pay 17 yuan - Li qiuqiong], [ABC card 10 yuan silver fund charity enriching Chen Yuying team Jintan Wang Jufang Shanghai Xue gendi team], [State Council's notice and declaration form on the state's welfare for meritorious persons], [State Council's notice and declaration form on the state's welfare for meritorious persons] [3 platform reward form, March 29, 2017], [Dutch crowdfunding project], [International Plum Blossom Association salary payment project], [ease fund settlement fee payment project], [Chinese national welfare fund 60 yuan project], [Guanghua Foundation (20 + 116 yuan) love fund settlement fee payment project], [harmonious home Shanghai team 9.9 yuan project], [China national welfare fund 60 yuan project], [Guanghua Foundation (20 + 116 yuan) love fund settlement fee payment project], [harmonious home Shanghai team 9.9 yuan project] [key meeting card fee for unfreezing national assets of bird's nest on April 25, 2017], [US dollar unfreezing (19667 + Xinbao 170) project], [platform reward fund project], [37 group project of four southwest teams of targeted poverty alleviation], [38 group project of four southwest teams of targeted poverty alleviation], [20 yuan tax paid for 16 yuan Chen Yuying project - 958 group], [investigation on targeted poverty alleviation of General Office of the State Council], [investigation on targeted poverty alleviation of General Office of the State Council] [Ningbo team Ministry of Finance and Red Cross donation project], [218 yuan project], [55 yuan project], [668 yuan project], [1680 yuan project], [35 + 23 yuan project of Sanfeng foundation of guoyuhuan East China Bureau], [Shanghai group of 958 national charity fund members], [20 yuan project of 958 group charity enriching people], [20 yuan project of guoyuhuan East China Bureau] [1000 yuan people's livelihood membership card]... And so on, Semi militarized management was adopted to incite nationalist sentiment. Everyone was required to change the background of their head portraits to red and take formal photos. Moreover, the flag was raised every morning, and activities were held at night when they went to bed. Everyone also had to sing together. In addition, ordinary members are not allowed to talk or pull people into the group at will. All kinds of so-called high return project report documents in the group, brainwashing MP3 lecture recordings of backbone members (such as voice content of CAI Baiping's speech, which was exposed by the Ministry of civil affairs of the people's Republic of China on December 16, 2016 pretending to be vice mayor of Nanjing and national executive president of aiib) (such as propaganda of Qi Lihua 169 project), photos of national leaders of PS presiding over the charity fund distribution meeting All kinds of fake central red head documents emerge one after another. Every night, there are propagandists to organize lectures. In addition to participating in these activities within the group, people in the group also need to sign a letter of commitment, resolutely follow the group leader, make rational use of donations, refuse to buy foreign procts, be willing and bear legal responsibility. In the context of swindlers, the old people are making contributions to the national rejuvenation. Deception not only brings persecution to the victims' families economically, but also some people are stubborn and even threaten to sever their relationship with their close relatives in order to accomplish their "great cause". Very bad nature (similar to MLM brainwashing money)! The consequences are very serious (property lost, family broken)! Extremely corrupt morality (cheating with patriotic feelings)
first, because the US dollar is relatively "valuable", for example, the current US dollar = 6.6155 yuan, so the base is small when converting bitcoin
Second, there is a price difference between Chinese and foreign bitcoin exchanges, for example, the price of the US exchange is generally 1% - 2% lower than that of China, and even 9% more often, plus the transaction and withdrawal fees, It will also lose part of the value of the currency
because domestic people invest more in bitcoin, and bitcoin is fixed and limited, it is inevitable that the price of bitcoin is high. This does not rule out that makers are pushing up the price. The number of users and trading volume of each exchange are different. The price of bitcoin is caused by many factors, especially for countries with foreign exchange control, The price difference between China and foreign countries will be relatively high--- Wan foreign exchange assistant
in fact, there are many specific applications, but they are all in the process of development and research and development. It can be said that the blockchain technology is not mature. Among many enterprises, Yingtang Zhongchuang has more development and application of blockchain technology, which has a certain impact on the future development of the Internet of things.
