Blockchain rate

1.

blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects

on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention

on December 2, 2019, the word was selected into the top ten catchwords of "biting words" in 2019

extended data:

Application of blockchain Finance:

since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain Technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency

standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency

in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016

the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology

2. Yes, but the hardware is constantly updated, so basically don't worry. A transaction only takes about 100 bytes, or 100 kb.

3. Before October 2018, it seems that the fastest one is REBO, next to EOS. After October, these public chains are basically silent in terms of speed, because bitconch of Baker chain has achieved 120000 TPS Based on many technical advantages, which makes it possible for applications to land. Therefore, the world's fastest public chain is the world's fastest public chain, which can be said to be the leader.

4. I don't know when the Internet of things has been deeply related to the blockchain, and it has become more and more intense this year. Whenever the Internet of things is mentioned, blockchain will follow; When it comes to blockchain, we must also bring the Internet of things into the topic. The public can't help but wonder whether the Internet of things rubs the heat of blockchain, or does the blockchain pull the Internet of things hard to block the "bullet"? Now let's explore

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

5g is 5g

blockchain is the third power of blockchain

it's not clear. Do you want to ask if the three logics of quantum computing

are different, and there is a little sense of mutual promotion

5g solves the problem of wireless transmission speed, which is many times faster than 4G

blockchain was formerly PPP protocol, It is the point-to-point transmission protocol

used to solve the congestion problem of the central node. Quantum computing to improve the download speed is a breakthrough of Moore's law, which can solve the limit problem of computing speed in the limited space

for more information, please refer to this article, what is blockchain, can you explain it easily

6. Colleagues are playing. What is a miner? To put it bluntly, it's the same as bitcoin. Get something by doing something on the Internet. We call this kind of behavior mining. The obtained minerals can be exchanged back and forth and wait for their appreciation to sell. However, we don't know how much it will cost to buy. I think it's OK to play as a daily leisure game, but don't put too much energy into it. At present, this thing is still very promising, but it may collapse one day. Anyway, it's all virtual procts. Since there is neither food nor specific value, it's very easy to turn it into waste. Just like the popular bitcoin in the previous period, there are few people playing it now.

8. Bitcoin market suddenly soared, and now you can buy it. But you have to buy by yourself. Think about it, because bitcoin is a virtual currency. Market uncertainty, buy carefully.
