Graphene technology of digital currency
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
the mechanism of filecoin, post spatiotemporal proof, is the consensus mechanism adopted by filecoin and the innovative computing power mechanism of filecoin, which is essentially a kind of storage proof. It takes the data stored by the user as the proof of the calculation force, and takes the amount of data used to prove a miner's possession in a period of time as one of the evaluation data of the block
before a miner submits a spatiotemporal certificate on the chain, the data stored by the storage miner must be quickly sealed in the sector to ensure that the miner does store the corresponding data before he can get the spatiotemporal certificate on the chain
in the hardware configuration of the filecoin miner, the reason why the graphics card is used is that a large number of post snark calculations are needed in a block time to solve the problem of fast sealing. At present, the best solution for snark computing is GPU rather than CPU
unlike bitcoin, the mining focus of filecoin is on storage, and the GPU is used to solve the computing time of PST proof. Therefore, CPU can improve the computing power, but the sealing speed of mining machine sector without GPU configuration will be much slower, and the block rate will be very low or even unable to block.
Generally speaking, the domestic customs declaration fee for imported ant mining machine is not much, and there is no problem with the data of goods arriving at the port. We need to confirm the 3C problem in advance, declare to the customs, pay taxes, and release. The focus is on 3C

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 laserthis 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 shiftsolubility: 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 moleculesSilicon based chips, which are used in mobile phones, are the mainstream procts in the world. For example, Kirin 9000 of Huawei and A14 of Apple both use silicon-based chips, and these two chips are the two most technologically advanced in the field of silicon-based chips, so it is very difficult to make them
However, with the improvement of silicon-based chip technology, many experts predict that the chip will soon meet its physical limit, and the room for performance improvement will become very small. For the future development of science and technology, researchers also need to start looking for new chips, in which graphene material is noticed by researchers in many countries and regarded as the only choice for future chips, How difficult is it to make graphene chips? What's the difference between it and traditional chips
to sum up, the biggest difference between carbon based chips and silicon-based chips lies in the different manufacturing methods and materials, and the performance is also greatly different because of the different core materials. However, although carbon based chips are very good, they can be seen from the technology mastered by China and other countries in the world, Carbon based chips may not be used in daily life in the next 10 years, but it is still possible to achieve commercial use
