Graphene technology blockchain

1.

Graphene, graphene, is the underlying technology architecture of blockchain created by EOS founder Daniel Larimer and cryptonomex team. Based on this architecture, Daniel has developed bitshares, stem, EOS and other far-reaching projects. The famous blockchain projects developed based on this architecture include Zoomlion auto chain, gongxinbao, karma, payger, echo, seer and so on

Zac chain is an electric vehicle intelligent ecosystem based on blockchain technology. Supported by the core technology of blockchain, supplemented by AI, big data, Internet of things and other technologies, and based on the vehicle traveling data recorder tntelligent tree as the carrier, it customizes an intelligent experience service system for electric vehicle users, covering both the front market and the back market. In the Zac chain network, users can fully control their own driving data, and enter the mining mode from the blockchain technology. Driving is mining, and driving is value. The Zac token generated by mining can be exchanged in the Zac chain ecosystem to solve the pain point of depreciation of users' car use

2. Based on graphene underlying technology, blockchain has decentralization, consensus mechanism, encryption calculation, information can not be tampered with, and high efficiency and transparency, which can effectively solve the instry pain point problem
with the decentralization of blockchain, there is no need to rely on the third-party platform for sales, recing the price difference between middlemen and direct sellers to consume independently by buyers
every commodity can be easily accessed from planting, proction, processing, consumption and after-sales, so as to avoid the expiration and counterfeiting of commodities
the price of every commodity is clearly marked. Once the information is generated, it can not be tampered with to ensure the rights and interests of businesses and consumers Weifang technology company reports for you.

3. This is relatively new, so each school's is not the same, generally belongs to the material related specialty, and sometimes belongs to physics.

Graphene is a kind of graphene, which consists of carbon atoms in the form of sp; Two dimensional carbon nanomaterials with hexagonal honeycomb lattice are composed of hybrid orbitals

the arrangement of carbon atoms in graphene is the same as that in graphene monoatomic layer, which is bonded by SP2 hybrid orbital, and has the following characteristics: carbon atoms have four valence electrons, three of which form SP2 bond, that is, each carbon atom contributes one unbound electron on PZ orbital, and the PZ orbital of adjacent atoms can form SP2 bond perpendicular to the plane π Bond, newly formed π The bond is half filled

The results show that the coordination number of carbon atoms in graphene is 3 and the bond length between two adjacent carbon atoms is 1.42 × 10-10 meters, the angle between the keys is 120 °

except for σ In addition to the hexagonal honeycomb structure, the PZ orbital of each carbon atom perpendicular to the layer plane can form a polyatomic structure through the whole layer π Bond (similar to benzene ring), so it has excellent electrical and optical properties

When the incident light intensity exceeds a certain critical value, the absorption of graphene will reach saturation. These characteristics make graphene can be used as passive mode-locked laser

this unique absorption may become saturation when the input light intensity exceeds a threshold, which is called saturation effect. Graphene can be easily saturated under visible strong excitation in near infrared region e to global optical absorption and zero band gap. Because of this special property, graphene is widely used in ultrafast photonics. The optical response of graphene / graphene oxide layer is tunable

Under more intensive laser illumination, graphene has an optical nonlinear Kerr effect with nonlinear phase shift

solubility: good solubility in nonpolar solvent, superhydrophobic and super lipophilic

melting point: in 2015, scientists indicated that the melting point was about 4125k, and other studies showed that the melting point was about 5000K

Other properties: adsorption and desorption of various atoms and molecules

5. The issuance of RMB in China has always adhered to the following three principles. The contents are as follows:

(1) the principle of centralized and unified distribution. Concentration means that the issuance right of RMB is concentrated in the central government, the State Council, which represents the country. Unification means that the people's Bank of China is authorized by the state to monopolize the issuance of currency. Except the people's Bank of China, no region, no unit or indivial has the right to issue currency or issue currency in disguised form< (2) the principle of planned issuance. It means that the issue of currency should be planned according to the requirements of national economic development. Specifically, the head office of the people's Bank of China shall propose a currency issuance plan, which shall be submitted to the State Council for approval before implementation< (3) the principle of economic distribution. The principle of credit issuance is the symmetry of financial issuance. It refers to issuing money according to the development of national economy and the actual needs of commodity circulation. This kind of issuance is to increase money supply on the basis of economic growth, in order to meet the objective needs of commodity proction and circulation for money. It will not cause price fluctuation and inflation

the opposite of economic issuance is fiscal issuance, that is, excessive currency issuance beyond the needs of economic development in order to make up the fiscal deficit. This kind of issuance mainly means that the finance overdraft or borrow money from the central bank, or the central bank directly purchases government bonds and treasury bonds. As a result, the money can not be recovered after it is issued, which eventually leads to inflation and affects the stability and sustainable development of the economy. In order to avoid financial issuance and ensure economic issuance, Article 29 of the law of the people's Bank of China (Revised) stipulates that "the financial department shall not overdraft from the people's Bank of China, and the people's Bank of China shall not directly subscribe to or underwrite treasury bonds and other government bonds."

The central bank should follow the following principles in issuing currency:

1. Concentration means that the issuance right of RMB is concentrated in the central government, the State Council, which represents the country. Unification means that the people's Bank of China is authorized by the state to monopolize the issuance of currency. Except the people's Bank of China, no region, no unit or indivial has the right to issue currency or issue currency in disguised form

2. It means that the issue of currency should be planned according to the requirements of national economic development. Specifically, the head office of the people's Bank of China shall propose a currency issuance plan, which shall be submitted to the State Council for approval before implementation

3. The principle of economic distribution. The principle of credit issuance is the symmetry of financial issuance. It refers to issuing money according to the development of national economy and the actual needs of commodity circulation. This kind of issuance is to increase money supply on the basis of economic growth, in order to meet the objective needs of commodity proction and circulation for money. It will not cause price fluctuation and inflation

extended data:

Central Bank's money issuance process:

1. Put forward the RMB issuance plan and determine the annual money supply. Every year, the head office of the people's Bank of China puts forward a plan for currency issuance and withdrawal in accordance with the state's economic and social development plan, which shall be submitted to the State Council for approval before implementation. Including the design, printing and reserve of tickets and coins

The State Council approved the money supply plan submitted by the people's Bank of China

3. The issuing fund is the currency to be issued kept by the central bank for the state. It is a reserve fund for currency issuance. It does not have the nature of currency. It is kept by the people's banks at all levels that set up the issuance Treasury. The head office is in charge of it. The right to use the issuance fund belongs to the general Treasury

4. The currency issue of RMB is mainly realized through the cash collection and payment business activities of commercial banks. After the commercial banks transfer the issuance funds of the people's Bank of China's issuance Treasury into the business Treasury, they pay the units and indivials from the business treasury through the cash cashier, and the RMB banknotes enter the market. This is called "cash injection."

at the same time, all commercial banks have to recover a certain amount of cash from the market every day. When the inventory currency of the business library exceeds the specified limit, the excess part should be sent to the issuing library for safekeeping. This is called "cash return". The process of currency from issue library to business library is called "issue", that is, currency issue; The process of money returning from the business library to the issuing library is called "warehousing", that is, money withdrawal
