Alibaba blockchain 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.

Ma Yun: I want to know what bitcoin can bring to the society
at the two sessions, Ma Yun... Oh, sorry, Comrade Ma Yun who doesn't want to wear a red hat didn't attend the two sessions
In November 2017, Alibaba, ant financial services and xiong'an signed a strategic cooperation agreement to build a "digital xiong'an blockchain implementation platform". At present, ant financial services has provided blockchain landing application technology in the rental field in xiong'an. It can be said that xiong'an has become the first pilot field of Ali in the overall implementation project of blockchain technology1、 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 blindBlockchain 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
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.
