China IOT ecological blockchain

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 tools

3. 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 behind

5. 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 model

Third, 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

2. At present, there are indeed many companies doing IOT blockchain. Although many large companies have not officially publicized it to the outside world, Oracle, Samsung, sap, Amazon, Google, Microsoft, IBM, apple, Internet, Alibaba, Tencent and Jingdong are basically involved in R & D and exploration in the field of IOT blockchain. At present, vertical IOT blockchain companies are relatively low-key, At present, I have met a company called chaincomp chain computing. If there are other similar companies, you are welcome to supplement and exchange.

3. Personally, I think the development of blockchain is still very good. Now it has risen to the level of national development strategy. In terms of ecology, you can learn about Wen ecology. I think the relatively complete ecological construction that I have come into contact with at present is Wen ecology.

4. Blockchain technology has been widely sought after since it came out, and is regarded as the leading technology of a new round of instrial revolution., At present, blockchain has gone out of the concept stage and is about to enter the era of blockchain 3.0. But unfortunately, there are still many security loopholes in blockchain technology in this era. Both blockchain enthusiasts and cryptocurrency speculators have heard and witnessed the endless debate about the limited transaction throughput and high fuel cost and low efficiency of blockchain, and deeply felt the bottlenecks and pain points of blockchain technology in these instries, which are greatly related to the inherent deficiencies of blockchain architecture
ecol ecol is an intelligent, efficient and molar blockchain ecosystem and application scenario solution with unified standards for the security vulnerabilities of blockchain technology, which is committed to building a programmable society with smart contracts. Ecol ecosystem enables the blockchain ecosystem to use blockchain, big data, Internet of things, artificial intelligence (AI), virtual reality (VR) and many other technologies to help people from all walks of life seamlessly connect the existing systems and services with the blockchain, and jointly accelerate the implementation of the blockchain from "technical concept" to commercial scene
ecol ecol has 10 core technological innovations compared with other "blockchain black technology". Main chain and side chain technology, cross chain communication, support high concurrency, inhibit block inflation,
both integration and division of labor, both security and convenience; Artificial intelligence
AI
coordination of molar intelligence system, to provide alternative functional moles; Unique virtual machines and smart contracts support all kinds of creative smart contracts; Block fog and fog storage fog computing technology, smaller network delay, fast response; Lower security risk; The al quantification of block structure and digital assets has great significance of standardization, normalization and unification of block structure and digital asset valuation; Matching hardware wallet, light wallet and cold wallet, it integrates all the functions of eating, drinking, basic necessities of life, work and life. The integration of blocks and transactions enables each transaction to directly participate in maintaining the transaction order of the whole network, which greatly improves the efficiency. Ten core technological innovations to jointly build a complete ecol ecosystem.

5. The distribution method and handling charge of different mines are also different. If you have enough money, bold enough or stupid enough, I think it's better to buy a few hundred tons of calculation and dig it by yourself.

6. I don't quite understand what cheap means:
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

7. Bitcoin is a kind of virtual currency, and there are risks in transaction. China does not recognize bitcoin, so it is necessary to consider it carefully and not be cheated
