Ⅰ What is blockchain and how to make money with blockchain

Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
The ways to make money in the blockchain are as follows:
1. Coin speculation. Coin speculation is like stock speculation. Coin speculation is the lowest threshold for making money in the blockchain;
2. Vendors, district Blockchain is a global market. Like small traders, you can move from a low-price platform to a high-price platform to sell and earn the difference;
3. Earn commissions for promotion. The blockchain method is to register first Exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you can get a commission;
4. Mining, "mining" in Bitcoin is The accounting process;
5. Technical support, providing blockchain technical support to some teams and enterprises;
6. Opening a trading website and charging handling fees;
7. Developing wallets and wallets It is the infrastructure of the blockchain, just like the "Alipay" or "WeChat Pay" of the blockchain;
8. Be a blockchain project or infrastructure equipment supplier.

Ⅱ [Autobot] 34 Trillion" "New Infrastructure" is launched, and the automobile industry is ushering in business opportunities

It is foreseeable that smart road infrastructure is expected to usher in rapid growth. New technology applications such as 5G-V2X, autonomous driving, cloud computing, high-precision maps, and sensor networks will board the "giant aircraft carrier" of the "new infrastructure" to ride the wind and waves.

In addition to the development of commercial vehicles and intelligent driving technology, looking back on the past, during the 4 trillion yuan investment in infrastructure construction in 2009 and 2010, my country's automobile sales growth rates reached 46.1% and 32.4% respectively, which was Since the China Association of Automobile Manufacturers started collecting statistics in 2001, they ranked first and fourth, which are the two years with the fastest growth rate in history. The abundant social funds caused by the massive infrastructure construction will indirectly benefit the automobile market. This time’s “new infrastructure” is different from the one ten years ago.What are the differences between the vast “old infrastructure”? Or is history starting all over again? It’s hard to tell now, but it’s certain that 2020 is destined to be extraordinary.

Ⅲ Which countries are currently leading in blockchain in the world?

At present, the countries that are leading in blockchain in the world are mainly as follows:

1. United States: The United States is one of the largest blockchain markets in the world, with many blockchain start-ups and technology giants. At the same time, the U.S. government is also promoting the application of blockchain technology. For example, the U.S. Securities and Exchange Commission (SEC) has approved the first securities trading platform based on blockchain technology.

2. Singapore: Singapore is one of the leaders in the blockchain field in Asia, with a number of leading blockchain companies and research institutions. The Singapore government is also actively promoting the application of blockchain technology. For example, the Monetary Authority of Singapore (MAS) has launched multiple blockchain projects, including blockchain-based payment systems and digital identity verification systems.

3. Switzerland: Switzerland is one of the leaders in the European blockchain field and has many blockchain start-ups and research institutions. The Swiss government is also actively promoting the application of blockchain technology. For example, the Swiss Federal Railways (SBB) has launched an electronic ticketing system based on blockchain.

4. Japan: Japan is one of the important countries in the blockchain field in Asia, with many blockchain start-ups and technology giants. The Japanese government is also actively promoting the application of blockchain technology. For example, the Japan Financial Services Agency has approved the first digital currency exchange based on blockchain technology.

5. South Korea: South Korea is one of the important countries in the blockchain field in Asia, with many blockchain start-ups and technology giants. The Korean government is also actively promoting the application of blockchain technology. For example, the Ministry of Land, Infrastructure, Transport and Tourism of South Korea has launched a real estate registration system based on blockchain technology.

IV Will blockchain trigger the 4th Industrial Revolution

The first industrial revolution brought steam power and factories. The second produced railroads and electricity. The third time gave us the internet, digital computers and the conveniences of the modern world.
These revolutions began and ended with the creation of better, more efficient machines. But the fourth revolution, Industrial Internet of Things (IIoT), asserts that it is coming, and it will not follow in the footsteps of its predecessors.
The focus of the fourth revolution will not be on stronger and faster machines: it will revolve around machines, processing, sharing, and spontaneous information behavior, fundamentally changing our relationship with tools and the world., the relationship between each other.
Data Revolution
It’s not coal, steel, or silicon. The currency of the fourth revolution will be data.
A single gas turbine, coupled to the industrial Internet, generates more than four times the data of the entire world’s Twitter in a day, but we analyzed less than 1% of the data. Bill Ruh, CEO of GE Digital, predicts that there will be a deluge of digital information that today’s analytical tools cannot hope to parse.
“Ten years ago, we were probably bringing in 1 terabyte of data every day,” Ruh said in an interview with The Boston Globe. “Today, that’s up to about 10,000 terabytes of data. By 2020, we expect to be bringing in about 1 terabyte of data every day. Millions of terabytes of data.”
The machines of the future will produce roughly the same amount of information every day as the U.S. Library of Congress. Imagine reading every book in the Library of Congress and then having to summarize what you learned in 10 pages. The task is not only huge, it's ridiculous.
The real miracle of the fourth industrial revolution will not be the data produced, but the intelligent machines that can analyze this data and communicate with their kind in the network. Each networked machine will then take action, changing its processes to become more efficient and feeding its changes back to the network.
Hopefully these smart machines will bring our world economy to a climax: Ruh and GE believe that over the next 20 years, the smart machines and IoT industries will add $10 to $15 trillion to the global economy. This is a huge increase considering that global gross domestic product (GDP) was approximately $74 trillion in 2015.
The Foundations of the Revolution
Two components are focused and necessary for the coming revolution: a centralized, industry-specific Internet communications network such as GE’s Predix; decentralized approach, as well as hindering dishonest communications to facilitate commerce.
Specific IIoT networks must serve as hubs for intelligent machines to interact with each other and with their human creators. Sensors on computers collect large amounts of data and then sift through the data in real time. In other words, it is conceivable that it occurs on the basis of a machine. But to relay equipment findings and make decisions without human intervention, to truly create a smart network, machines need a single communication network.
Imagine that while the plane is still in the air, sensors in the plane's engine identify a part that is about to fail, then communicates to the destination airport that the engine will need maintenance and orders replacement parts before landing.
This kind of intuitive machinery is no sci-fi dream: it's our future.
I believe that IIoT information network is only half the battle, ultimately it is still about e-commerce. Think of it like public roads that millions of self-driving cars will someday be running on.
Right now, these self-driving cars run a single system. But how do we ensure that every self-driving car will obey traffic rules? like meHow do we ensure that in the event of an accident, the vehicle is not sending fraudulent messages regarding its whereabouts? If the accident happened between just two parties, then each passenger would corroborate his own car's story, and there would be no way to verify each party's claimed location.
Consider that decentralized, satellite-based GPS will impact the situation. This system is impartial and connected to every vehicle. Of course, each car can continue to lie, but it's much simpler to verify which party is telling the truth.
Due to the non-cancelable nature of the GPS system, self-driving cars have no reason, or have been tampered with by their owners, to lie about their location in the event of an accident. This strong incentive for integrity is tantamount to promoting trade among self-driving cars and is necessary to make owners feel that their investment in these vehicles is safe.
GPS technology is to autonomous vehicles what network blockchain technology is to the industrial Internet. Of course, self-driving cars can drive on the road without GPS, but their owners probably won't allow them to do so. Likewise, at a larger scale, machines can communicate on a single, centralized network of the Industrial Internet, but must do so without risk. (Blockchain BlockChain is the core part of Bitcoin BitCoin technology. Its function is simply similar to a ledger that records all transaction data. This ledger: 1. Stored on various Bitcoin nodes on the Internet, each node There is a complete backup; 2. It records all Bitcoin transfer transactions since the birth of Bitcoin; 3. The ledger is stored in blocks, and each block contains a part of the transaction record. Each block records the previous block. The id of the block forms a chain structure, so it is called a blockchain; 4. When you want to initiate a Bitcoin transaction, you only need to broadcast the transaction information to the P2P network, and the miners will record your transaction information into a The new block is connected to the blockchain and the transaction is completed.
Blockchain has spurred revolutions elsewhere
Of course, blockchain has facilitated the growth of e-commerce in the financial industry. But digital Packets of information are discrete assets like currency, and blockchain can create a digital record of their existence and transmission. The technology is essentially a record, or unified ledger of digital events. This ledger is dispersed across the network and is shared between different parties and can only be updated by a unanimous majority of those parties. Once a ledger item is created, it can never be erased.
Blockchain is the missing link in the revolution because it Incentivized e-commerce will define trust between machines and stakeholders. Take, for example, Volkswagen’s recent emissions scandal. Volkswagen’s tests showed that its vehicles emitted too much nitrogen oxide, so it chose to hide the problem to avoid subsequent inspections.
While blockchain will not prevent machines or humans from tampering with the data, it will create transparent, shared, and indelible documentation of the original emissions data. If this data has already been created and passed through the blockchain system Share, the public will never fall into fraudpath, as the differences between the two datasets are clear.
The benefits of IIoT are obvious, we have developed machine-to-machine communication technology; now, it is the standardization challenge between society and the next revolution. This has driven database technology over the past three decades, and we're finally seeing momentum building towards it.
Different businesses have different goals, but if we all want to benefit from the efficiencies brought about by the Fourth Industrial Revolution, we must adopt a single model of machine-to-machine e-commerce. And since communication networks must operate commercially between willing participants, we must integrate blockchain into this system. Under the delicate environmental conditions that require constant modification of data and unfettered information trade, blockchain is the best path towards a new industrial revolution.

IV Future new trends in the global supply chain 1, board the express train of "blockchain" technology

The outbreak of the pandemic has reduced the flow of global goods. Cargo sluggishness at ports is a particular side effect of the COVID-19 pandemic, a supply-demand mismatch that has left manufacturers in various countries waiting months to produce or assemble raw materials and components.

Consumer demand is revitalized as COVID-19 lockdowns are lifted and government relief spending begins. However, supply chains cannot be synchronized, and production lines will slowly return to full operating capacity after being closed or curtailed.

In the automotive industry, reduced supplies of plastic components, petrochemicals and semiconductor chips used to control power windows, airbags and dashboards have led most manufacturers to production capacity decreased. The chip shortage has also halted production of computers, smartphones, medical equipment, vacuum cleaners, refrigerators and smart devices.

Like a flurry of activity, consumer demand suddenly stopped as the pandemic hit, and then when the economy came back to life, government largesse added additional As cash was put into people's pockets, consumer demand suddenly returned.

But when demand plummeted early in the pandemic, supply chains slowed to a trickle. When demand picks up, it takes suppliers longer to catch up, leading to months and months of delays. Now, supplies are being shipped, but there are only so many containers available.

Shipments at the port are also delayed due to a shortage of longshoremen and truck drivers. Once container ships are unloaded at congested ports, the goods are transported by rail and heavy semi-finished goods to factory loading docks, distribution centers and retail stores. But like other businesses, trucking companies are finding it difficult to predict demand and have significantly scaled back hiring. Demand for truck drivers is surging right now, but many are finding their jobs in the first few months after the pandemicIt replaces sex work.

Vertical vertical integration: A solution to supply chain problems?

Acquiring a small supplier whose production capabilities can be fully absorbed by an acquiring company is a move that many companies are currently considering. Such purchases seem most likely to become common transactions, based largely on stock and employment contracts and cash incentives, each tying the entity's management to ongoing operations and changing ownership.

After World War II and the Great Depression, a well-educated workforce and advanced infrastructure catapulted the U.S. economy to a leadership position unsurpassed in 80 years.

The pandemic has prompted some company executives to readjust the supply chain management playbook. The biggest lesson companies have learned from the supply chain crisis is the need to improve sales forecasting.

When a black swan event occurs, your idea of ​​making predictions based on historical trajectories has little value. The CFO must evaluate real-time demand data and work closely with procurement and sales. Daily sales data need to be compared with purchasing data. Finance can then decide where capital must be allocated to maintain supply chain resiliency.

In the future, CFOs may be able to use blockchain technology to assess in real time whether suppliers and shippers can keep up with demand. Within the blockchain, participants will record transactions, pricing, dates, locations, quality, certifications and other data needed to manage the supply chain. Blockchain platforms will provide this visibility.

Blockchain can also be used to create "zero-latency" supply chains. Instead of large numbers of suppliers that are not tightly connected or loosely coordinated, they can now be digitally interconnected in centralized supply networks. Companies may be reluctant to join such a network due to concerns about data control, security and privacy, but users can manage access to information through data encryption.

A few years ago, there was a lot of interest in blockchain solutions, but then it fell off the radar. Due to the current market chaos, Americans have begun to study it again.

Due to rapidly rising demand and concerns about the impact of delayed deliveries on competition. In the United States, some large companies are now interested in using blockchain solutions again, showing great interest in supplier tracking and traceability, especially for logistics elements.

The global supply chain is disrupted and logistics costs continue to soar.How should the manufacturing industry break through?

Tianmu Academy, tomorrow will be better!

VI New inventions in the 21st century

1. Graphene new material

Graphene It is a two-dimensional material only one carbon atom thick, and its carbon atoms are arranged in the same arrangement as a single atomic layer of graphite. Although graphene is only one atom thick, its structure is very stable, 200 times stronger than steel, and it has good elasticity. It is considered a revolutionary material in the future.

On March 31, 2018, China’s first fully automatic mass-production graphene organic solar optoelectronic device production line was launched in Heze, Shandong. The project mainly produces graphene organic solar cells that can generate electricity under low light ( (hereinafter referred to as graphene OPV), solves the three major solar power generation problems of application limitations, angle sensitivity, and difficulty in shaping.

2. Shared bicycles

Bicycle manufacturing companies were once a marginalized traditional industry, but with the expansion of China's shared bicycles overseas, they have become a sunrise industry. This year, the overseas shared bicycle production capacity of Ofo and Phoenix will reach 1 million units. After sweeping across China, shared bicycles appeared in Cambridge, the "Bicycle Capital of the United Kingdom".

3. China’s high-speed rail

High-speed rail technology originated in Japan and Europe, but now China is leading the way. Traveling through the Saibei wind zone and over the mountains and rivers of Lingnan, from a single line between important cities to the "eight vertical and eight horizontal" blueprint is slowly unfolding. Entering the second decade of the 21st century, rail transportation began to be led by China's high-speed rail. High-speed rail has not only become the first choice for many people to travel, but also effectively promotes economic and social development.

4. Blockchain

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. , first proposed by Satoshi Nakamoto in Japan in 2008.

Blockchain makes hybrid consistency possible, making it suitable for recording events, titles, medical records and other activities that require data collection, identity management, transaction process management and provenance management. Blockchain has huge potential for financial disintermediation and has a huge impact on guiding global trade.

5. SixthSense

SixthSense comes from a magical high technology, which is named "Sixth Sense Communication Technology". It is said that this device costs only US$350, and it allows you to enjoy various services anytime and anywhere without changing your daily habits.

For example, if you go to the supermarket to buy something and want to search for some information about the item you bought, you can use the camera in the technology device to obtain some information on the packaging of the item for online query. .
