What does the DAG of virtual currency mean

1. Both camp and double signaling pathways are G protein coupled signaling pathway 1 and cAMP signaling pathway. After the signal molecules bind to the receptor, they proce the second messenger in the cell through the coupling with the GTP binding regulatory protein (G protein), thus causing the cell response. CAMP signaling pathway is composed of five components on plasma membrane: ① activated hormone receptors (RS); ② Inhibitory hormone receptor (RI); ③ Activated regulatory proteins (GS) that bind to GDP; ④ Inhibitory regulatory protein (GI) related to GDP; ⑤ Adenylate cyclase (c) 1) RS and RI RS and RI are located on the outer surface of plasma membrane, recognize extracellular signal molecules and bind to them. The receptor has two regions, one interacts with hormone, the other interacts with G protein 2) GS and GI G protein, also known as coupling protein or signal conversion protein, couple the receptor and adenylate cyclase to make extracellular signal transmembrane into intracellular signal, namely the second messenger cAMP. (3) the catalytic unit of adenylate cyclase cAMP signal pathway is adenylate cyclase binding to the plasma membrane, which catalyzes ATP to proce camp. The main effect of cAMP signaling pathway is to activate target enzyme and turn on gene expression, which is completed by protein kinase A. ① Activation of target enzyme: through the activation of protein kinase A, the downstream target protein is phosphorylated, which affects cell metabolism and cell behavior. It is a process in which cells rapidly respond to extracellular signals. ② Turn on gene expression: a process in which cells slowly respond to extracellular signals, which is the effect of cAMP signaling pathway on gene expression. The response chain involved in this signaling pathway can be expressed as: hormone G protein coupled receptor G protein adenylate cyclase Camp Camp dependent protein kinase A gene regulates protein gene transcription. 2. The external signal molecules bind to the receptors and hydrolyze the phosphatidylinositol-4,5-diphosphate (PIP2) on the plasma membrane into two second messengers: inositol-1,4,5-triphosphate (IP3) and diacylglucoside (DG). The most important feature of phosphatidylinositol signaling pathway is that two intracellular messengers are generated simultaneously after the extracellular signal is received by the membrane receptor, which respectively start two signal transction pathways, namely IP3-Ca2 + and dg-pkc pathway, to realize the cell's response to the outside world. Therefore, this signaling system is called "double messenger system". IP3 is a water-soluble molecule, which can mobilize endogenous Ca2 + in cells and increase the concentration of endogenous Ca2 + in cytoplasm. Ca2 + inces cell response through calmolin; DG activates protein kinase C (PKC). In many cells, PKC activation enhances transcription of specific genes. There are two ways: 1) PKC activates a cascade of protein kinases, leading to the phosphorylation and activation of gene regulatory proteins; ② The activation of PKC leads to the phosphorylation of an inhibitory protein, which releases the gene regulatory protein from the inhibitory state and enters the nucleus to stimulate the transcription of special genes.

5. 1 RMB = 0.4665 Malaysian yuan
there are 100, 50, 20, 10, 5, 2, 1 Malaysian banknotes, 20 and 2 are no longer printed, but they are legal tender. The unit of a note is called zero Ji, while the unit of a coin is 1, 5, 10, 20 and 50 cents, but in Malaysian it is called Sen.

6. According to the Bank of China (updated at 05:16 on September 14, 2016), the middle rate of foreign exchange market transaction: 1 Malaysian ringgit = 1.6268 RMB, please adopt!

7. There are three stages in the development of Digital Economy: "on the computer", "on the Internet" and "on the chain"
digital economy stage 1.0, "on the computer" is the era of computing, the popularity of personal computers, the computational economy model with computing power as the core competence, social laws supporting computer world software right law, and the representative enterprises are IBM, Intel, Microsoft, etc
in the digital economy 2.0 stage, the "Internet" is the era of information network, the popularization of technology elements represented by smart phones and the Internet, the network economy mode with communication power as the core competence, the social law supporting GPDR and Internet court, and the representative enterprises are apple, Qualcomm, Google, Amazon, Facebook, etc
in the 3.0 stage of digital economy, "on the chain" is the era of digital power network. 5g and distributed Internet are the representatives of the popularization of science and technology elements. The digital power economic model takes the power as the core competence. Social laws support the digital power law, representing Huawei, Ethereum and bitcontinent
digital economy is a new type of digital economy system with the development of digital economy to the stage of 3.0. It is a new type of digital economy system in the digital world built by the new generation of information technology such as blockchain 3.0. The digital world is the "new continent" of the global economy, and a digital world (Digital Earth) parallel to the real world. Blockchain 3.0 technology is the general name of abcdfi and other technologies (artificial intelligence, blockchain, cloud computing, big data, 5g, Internet of things). Based on the blockchain 3.0 technology of distributed ledger, a digital rights and interests world of "data rights and interests" is being established. Through the "digital right copier" technology, all the assets rights and interests (physical assets, intangible assets, etc.) in the real world can be confirmed by data, which can be freely transferred in the real world and the digital rights world, realizing the value transfer[ 1] Different from the Internet economy (digital economy 2.0 era), the information economy mode of circulation, the digital rights economy (digital economy 3.0 era) is the circulation of digital rights and interests, that is "digital rights", which will open the era of digital rights trade, which is 100 times the scale of the global economy, and lay the foundation for the intelligent economy (digital economy 4.0 era).

Blockchain technology originated from "bitcoin: a point-to-point e-cash system" proposed by Nakamoto Cong, in which "block" refers to each information block contains a time stamp, and the information blocks with time stamp are connected with each other to form an information block chain, namely "blockchain"

blockchain is a technical solution to collectively maintain a reliable database through decentralization and distrust. From the perspective of data, blockchain is a distributed database in which a single node or multiple nodes cannot intentionally change data records. Its distribution is reflected in the distributed storage and distributed records of data. From the technical point of view, blockchain technology is a new technological achievement after the integration of a variety of technologies. After the combination and development of a number of technologies, it forms a more efficient way of data recording, storage and expression
