Blockchain has become a new hot spot for innovation and entrepreneurship, and technology integration will expand new application space
3. Blockchain will be widely implemented in the real economy in the next three years and become an important support for the construction of Digital China
4. Blockchain creates a new platform economy and opens a new era of sharing economy
5. Blockchain accelerates the process of "credible digitization" and drives finance to "move from virtual to real" to serve the real economy
The blockchain supervision and standard system will be further improved, and the instrial development foundation will continue to be consolidatedA: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare
First, in the field of finance,
blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields
Second, the Internet of things and logisticsblockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management
Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs Sixth, the data stored on the public welfare fieldblockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision
kuaishang takes the lead in applying blockchain technology to the voting field nationwide, effectively solving the trust problem of voting data, providing the most real and effective data for the participants, protecting the rights and interests of real voting users, and making blockchain technology "people-friendly", so that the general public can quickly perceive and share the information in the field of life services Enjoy the convenience of blockchain technology
Application of blockchain technology in digital asset registration
Jinzhu digital asset service platform takes the lead in using blockchain technology, which is a global distributed ledger technology with the characteristics of traceability, non tampering and non forgery. The digital assets of the platform come from the standard issuers of digital assets, and the asset value is determined by the open market to avoid overestimation or undervaluation
the application of blockchain technology in the financial instry
ant financial's independent and controllable financial grade commercial blockchain platform has been deployed in multiple social and commercial application scenarios by multiple institutions and countries. Ant blockchain platform supports second level confirmation for transactions, and the consensus mechanism uses efficient parallel consensus algorithm to ensure the high performance of the blockchain platform, Ant blockchain has been applied in many proction level applications, applying leading technologies to people's livelihood, commerce, finance and other fields.

the technical basis of blockchain 2.0 era is as follows:
1.
smart contract; It is an application in the blockchain system. It is a business logic that can run automatically by coding. It usually has its own token and special development language<
2
3.
virtual machine: it is used to execute the compiled code of smart contract. Virtual machine is Turing complete
with the application and deepening of blockchain technology, the era of blockchain 3.0 has come. The mode of blockchain cooperation can be seen from behind the operation of all walks of life. Therefore, blockchain will change the way of human life widely and profoundly, so the whole life service will enter the era of blockchain. In the process of Internet development, blockchain + physical instry, blockchain e-commerce and blockchain community operation can be applied to blockchain technology
of course, 3.0 came into being with the development of modern cryptography. Today's applied cryptography is the result of cryptography 20 years ago. Therefore, in order to apply blockchain technology to more participation scenarios, especially in Internet economy and other aspects, more verification is needed to verify whether the existing encryption technology can meet the demand, and more in-depth integration of cryptographic frontier technology and continuous innovation are needed.
at present, China's blockchain instry mainly focuses on computing infrastructure, radiates digital currency, and derives to the penetration process of blockchain application. Infrastructure includes chip miner, mine pool and cloud computing power. Digital currency, wallet and exchange constitute the monetary system. Asset authentication, financial services and charity form a rich application ecology. From the development trend, the mining machine has experienced CPU, GPU, FPGA, until now through ASIC chips to customize mining, we can see from the mining machine calculation force curve that the mining machine calculation force has been in a soaring trend.

first of all, mining does not start from a trainer. Holding a hoe in hand, you can be a qualified miner. Patience, time and familiarity are essential to the distribution of minerals you need
-
there are many minerals in the roots of mountains, trees and grass - the minerals in world of Warcraft are mostly distributed at the foot of mountains, ridges, hillsides and the bulges of plains. If you want to mine more, fly more in those corners
-
the mines on each map have a fixed refresh time. If you plan to mine on one map for a long time, you can sell ah to other players who need it even if you don't need it
-
if you want to have high efficiency and try to enter the hole as little as possible, you are not recommended to enter the hole for one mine unless you see rare ore, rich XX ore or more than three ore spots in this hole on the gray ore spot of the small map
-
if it's the gathering instry, you will definitely meet competitors. When the plug-in shows that there are a large number of mineral spots on this map, and you haven't seen a mine for a long time, there must be a miner in the 1-2min flight distance in front of you. At this time, there are two options: first, go to other maps to proce the required minerals; second, try to fly backwards, He disrupted the rhythm of mining and the route of mineral refresh on the map
-
in the process of mining, we often encounter rare minerals that are not needed in the manufacturing list, such as gold and silver, krypton gold, Titan and so on, so we can mine them. A lot of gold can be sold
-
put one or two sets of hot flow anvil made by engineering in the bag. You don't need to run around to find the furnace or anvil. It's better if you have mop rare gloves of plunderers. If you want to go to the mining specialty, it's recommended to take F gloves that you don't need to collect, and take them with you when mining. Maybe you can help when it's critical< br />
