What is blockchain gold

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

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. At present, blockchain projects can be divided into four categories: currency, platform, application and asset token. Currencies mainly act as the "exchange medium" of blockchain assets, belonging to the general equivalent, similar to the previous gold. Applications in this category include bitcoin, lightcoin, etc. You can learn more about it online
I hope it can help you, please accept it if you are satisfied, thank you!

3. The relationship between bitcoin and gold
bitcoin, a blockchain based digital currency, is often regarded as a global safe haven asset like gold. In this age of global turmoil, even gold has become unreliable and may be confiscated as India has. Some people have begun to think that bitcoin can replace gold, because bitcoin not only has the reserve capacity of gold, but also has some capabilities that gold does not have, such as low handling charges, rapid transfer capacity, decentralization and so on. With the increasing popularity of bitcoin and the decreasing volatility, the status of gold has been threatened
will bitcoin shake the status of gold?
gold has a long history, almost as long as the history of human civilization, and has withstood numerous tests in history. Bitcoin is less than a decade old, but its value has risen sharply. There is no support behind bitcoin. Of course, since the end of the gold standard, there has been no support from other currencies, except that there is no support from the central bank behind bitcoin. It's hard to predict whether bitcoin will exist in the next decade, a hundred years or even a thousand years.

4. Gold is a general equivalent, hard currency. All currencies are based on gold. Therefore, in addition to issuing currency, every country should also pay attention to gold reserves. Inflation means that more money is not worth money, and the reference object is also gold. It can be understood that gold is no longer the problem of value preservation, but gold is the general reference of value

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
from the two concepts, the main differences are as follows: gold is a physical object and a general equivalent; Bitcoin is a virtual currency, which is easy to be manipulated, and its value has a certain degree of hype.

5. There is no direct link between gold and bitcoin< Both of them are not money:
money is widely accepted as a medium of exchange. Gold is classified as money, which can be traced back to the early capitalism. At that time, gold could be used to exchange anything, but it didn't play much role. Gold is often in short supply. As a tradable tool and asset currency, it can be exchanged for a certain amount of US dollars
bitcoin has now become a means of online and offline payment, which has been accepted by many countries, but it has not been accepted by the whole world
2. The two are not irreplaceable: gold was used a long time ago, but it was rarely found and created by substitutes like gold. Bitcoin has many substitutes. Who knows what other encrypted electronic currency and technology will destroy the current market
3. Gold is a commodity, but bitcoin is not
gold is a basic commodity or hard asset that can be used in business, and can be used as a material to proce other commodities. People can also use gold for physical delivery and then make it into some other form for use. Although bitcoin is storable, it is not physical and cannot be held, felt or transferred
4. Are bitcoin and gold risk averse
bitcoin and gold are rare, their prices may be volatile, and each of them serves as an alternative investment to those who lack confidence in fiat money and monetary policy. Bitcoin trading is not as easy as gold, because people have to buy bitcoin through online trading platforms or invest in over-the-counter bitcoin trusts.

1、 Deng Yaping is a beautiful and talented girl. She was admitted to university at the age of 15; He became a university teacher at the age of 19 and was admitted to the graate class of the Chinese Academy of Sciences at the age of 22; At the age of 24, he taught graate students in the Chinese Academy of Sciences. Then she fell in love, married and had children. Everything went smoothly, with flowers and applause everywhere. However, when she was 29 years old, god suddenly closed the door to happiness and pushed her into the dark abyss. Her optic nerve was damaged and she was blind. Along with the light, she lost her husband and children

She wants to learn Braille and go back to her field of knowledge. But this year, she was 30 years old. Of course, a 30-year-old woman can't go to school for the blind. So she had to teach herself. She began to read Braille. Of course, she "looks" with her fingers. She could only touch with her fingers instead of her eyes. The first English word she touched was Chinese cabbage, and the letter was c-a-b-b-a-g-e. she touched the seven English letters with her hands and feet for an hour, but she still didn't understand that the word was "Chinese cabbage". When her father told her the answer, she cried. She wept for her clumsiness. She is an English professor at the Chinese Academy of Sciences. She doesn't know the English word "Chinese cabbage". Before that, she could read everything at a glance! She didn't believe that she was tripped over by a cabbage. She wants to live, she wants to stand up, she wants to be a Chinese cabbage that can fly and soar in the sky of knowledge again. She started her own struggle. She locked herself in the room, practicing over and over again, touching words over and over again, memorizing them over and over again. Then she recited what she had learned to her father. Once, when listening to her recitation, my father found that the blind words were full of red blood. When she finished reciting, her father took her hand and found that her fingers were worn out. Her father held her hands in his own and could not help crying. The father said, "daughter, we won't learn. Dad has a salary, and he can support you all his life. " She didn't cry. Instead, she comforted her father with a smile and said, "Dad, you must believe in your daughter. I can do it!"

One night, she sneaked out of the house by herself. Father is very anxious, looking around. Finally, her father found her in the classroom where she worked. The students are out of school. The light in the classroom has gone out. She stood alone on the platform, repeatedly measuring the blackboard with her hands. She finally returned to the podium. Everything is the same as before, so that after two weeks of class, the students don't know that their teacher is blind. Finally, some students found out that she was walking in the campus with a blind stick. Only then did they know her misfortune and her hard work in order to have a good class. The students were moved to cry, but she laughed. She told the story of the struggle of a Chinese cabbage with a smile, and encouraged the students to cherish the time

Her name is Yang Jia. After learning Braille, Yang Jia used computer Braille software and set foot on the fast track of her career. As a blind person, she was admitted to the Kennedy School of government, Harvard University, USA, majoring in public administration, and received a Harvard MPa degree. Now, Yang Jia is vice chairman of the UN Committee on the rights of the disabled, member of the 11th CPPCC National Committee and vice chairman of the China Association for the blind

Blockchain 4.0 is the landing of a large number of scene applications and the deep integration of multiple fields, such as blockchain plus artificial intelligence, supercomputing, big data, etc., which requires and promotes the upgrading of the underlying infrastructure construction, greatly improves its inclusiveness, carrying capacity and scalability, builds its solid ecological network system, and makes the blockchain value network radiate more scenes, Value is more reflected. The block chain structure is as follows:

as a new generation of public chain, SPG super gold puts forward its own innovation on the basis of absorbing the advantages of public chain in the past. Considering that Neo has its own unique advantages in solving the problems of low scalability, low concurrency and low transaction feedback of the public chain, and has achieved practical results, at the same time, in the super gold cryptocurrency SPG generation mode, it prefers the mining output mode under the more decentralized workload proof mechanism, Therefore, super gold creatively launched a two-tier structure combining transaction verification with Ethereum workload proof algorithm ethash, which separated transaction verification and block packaging synchronization, so as to better solve the problems of low scalability, low concurrency, low transaction feedback and block congestion of blockchain, At the same time, the smart contract system of super gold is more suitable for the development trend of current blockchain technology. The support of cross chain protocol for cross chain transaction can help build a public chain platform with higher universality, wider application range and more prosperous and stable ecology. Therefore, SPG super gold can be classified as blockchain 4.0 array

9. The gold token issued by digix is the gold in the digital asset world. It is a typical representative of asset token project. How can it be linked with gold
gold is the best choice for risk aversion. The gold token issued by digix is the gold in the world of digital assets, and its token, DGX for short, can play a role of hedging in the world of digital assets
How can DGX benchmark gold? It will be gold assets on the chain (that is: blockchain) operation. For example, if you have a kilogram of gold ready for sale, you can cut the gold for sale, but it is too troublesome and easy to cause loss. You can also send 1kg of gold to Singapore for LBMA to verify the gold. After the verification, the certificate of ownership of gold assets will be issued to you
the digital certificate can be converted into 1000 DGX tokens, i.e. 1 DGX token = 1 gram of gold. The circulation efficiency of gold has been greatly improved. Similarly, when you need to extract gold, as long as you have the corresponding token, you can replace it with a certificate to extract gold.

10. Network gold, international common name e-gold, referred to as EGD. Based on the world's most advanced blockchain technology. The global total amount of EGD is about 84 million pieces, and the number of EGD graally released and circulated in the global Internet within 100 years is about 42 million pieces. Online gold points are not money, but as a kind of consumer asset given by global commercial consumers from businesses. They are used to replace the points issued by businesses in traditional commercial society, realizing the networking, integration and capitalization of global commercial points.
