Stories of decentralization
Decentralization is a form of social relations and content proction formed in the development of the Internet. It is a new type of network content proction process relative to "centralization"
decentralizing is not to do without the center, but to let the nodes freely choose and decide the center. In short, centralization means that the center determines the node. The node must depend on the center, and the node cannot survive without the center. In a decentralized system, anyone is a node, and anyone can be a center. Any center is not permanent, but phased, and no center is mandatory for nodes
extended data:
in a system with many nodes, each node has a high degree of autonomy. Nodes can connect freely to each other to form a new connection unit. Any node may become the stage center, but it does not have the mandatory central control function. The influence between nodes will form nonlinear causality through the network. This open, flat and equal system phenomenon or structure is called decentralization
with the deepening of the interaction between subject and object, the constant balance of cognitive function and the continuous improvement of cognitive structure, the indivial can be released from the egocentric state, which is called decentralization

From the perspective of Internet development, decentralization is the form of social relationship and content generation formed in the process of Internet development, and is a new network content proction process relative to "centralization"
compared with the early Internet (WEB 1.0) era, today's Internet (Web 2.0) content is no longer proced by professional websites or specific groups of people, but is the result of the joint participation and equal power of all Internet users. Anyone can express their views or create original content on the Internet to proce information together
with the diversification of network service forms, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together
since then, with the emergence of more simple and easy-to-use decentralized network services, the characteristics of Web2.0 have become more and more obvious. For example, the birth of services more suitable for ordinary Internet users, such as twitter and Facebook, has made it easier and more diversified to proce or contribute content to the Internet, thus enhancing the enthusiasm of Internet users to participate in the contribution and recing the threshold of procing content. Eventually, every netizen becomes a tiny and independent information provider, making the Internet more flat and content proction more diversified
from the perspective of astronomy, decentralization refers to the fact that the universe has no center, that is, a boundless mass without a central point
De flow means that all social resources can be aggregated and distributed with one click
in a system with many nodes, each node has a high degree of autonomy. Nodes can connect with each other freely to form a new connection unit. Any node may become the stage center, but it does not have the mandatory central control function. The influence between nodes will form a nonlinear causal relationship through the network

compared with the previous Internet (WEB 1.0) era, today's Internet (Web 2.0) content is no longer proced by professional websites or specific groups, but by the participation of the whole Internet users and the creation of equal power levels. Anyone can express their views on the Internet or create original content to proce information together

transaction confirmation takes a long time. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed
the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading
the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless.
Decentralization means no center
extended meaning: with the deepening of the interaction between subject and object, the continuous balance of cognitive function and the continuous improvement of cognitive structure, the indivial can be released from the egocentric state, which Piaget calls decentralization

Boyle one day, Boyle's gardener sent a basket of beautiful violets to his study. After appreciating the bright color and fragrance of the violets, he picked a bunch of them and walked to the laboratory. As he walked, he pondered that alum (sulfate of heavy metal) might be distilling to proce alum oil (concentrated sulfuric acid) in the laboratory now. I don't know how it is going? I went to the laboratory and pushed the door open. I saw a continuous stream of smoke from the distiller to the glass receiver
as usual, he had to check the work of the experimenters every day. At this time, he put the violet on the table and poured sulfuric acid. All of a sudden, the irritating sulfuric acid vapor came out of the bottle mouth and quickly spread around the table. After distillation, he picked up the violets and prepared to go back to his study. At this time, he found that the violet was also smoking slightly, because the acid foam had splashed on it
he thought that the acid foam should be washed away, otherwise the violets would be corroded, so he put the flowers in the basin and sat in front of the window. After a while, I found a miracle in the basin! These violets turned red
Boyle threw the book aside, immediately picked up the flower basket and returned to the laboratory. Ask the experimenter to prepare several cups, fill each cup with an acid and inject some water. Then he divides the violet into several small bundles and puts them into various acid solutions. He watched quietly and found that the purple blue of the flowers graally turned to light red, and after a while they all turned red The first emperor of Qin imagined that the throne would last forever, that the dragon body would last forever, that he would think of medicine every day, and that he would dream of gold and silver at night. They lived in the mountains and lived a life of immortality. Alchemists use red sand (mercuric sulfide) and realgar (arsenic sulfide) as raw materials for smeltingpeople will never die of old age if they try to make elixir, then turn stone into gold, take elixir or use gold and silver as dishes. Westerners also follow the example of darkrooms or caves. They live alone and devote themselves to alchemy. One or two thousand years later, there is no lack of people who died in the elixir. The golden elixir disappeared in vain. Chinese and foreign ancient alchemists engaged in chemical experiments all their lives. Why did they achieve nothing? Because it goes against the laws of science
Third, iodine and fingerprints in movies, we often see the plot of police officers using fingerprints to solve cases. As long as we press on a piece of white paper with our fingers, then point the place on the paper where we press our fingers at the mouth of the test tube with a small amount of iodine, and heat the bottom of the test tube with an alcohol lamp. When the purple iodine vapor sublimed in the test tube comes into contact with the paper, the invisible fingerprint on the paper will graally show up, and a very obvious Brown fingerprint can be obtainedif you collect this piece of white paper and do the above experiment a few months later, you can still show the fingerprints hidden on the paper. This is because everyone's fingerprints are not exactly the same, and the fingers always contain grease, mineral oil and sweat. When you press your finger on the paper, the oil, mineral oil and sweat on the fingerprint will stay on the paper. It's just that people's eyes can't see it
The pure iodine is a kind of purple black crystal with metallic luster. Interestingly, when most substances are heated, they generally have three states: solid state, liquid state and gas state. Iodine, on the other hand, can be directly converted into vapor without liquid when heated. The phenomenon of direct gasification of solid substances such as iodine is called Shenghua At the same time, iodine is easily soluble in organic solvents. Because the fingerprint contains oil, sweat and other organic solvents, when the iodine vapor rises, it will dissolve in these organic solvents, so the fingerprint is also displayed The carbon dioxide gas exhaled by people can put out the fire, yellow sand can put out the fire, and water can also put out the fire. You know what? Copper wire can also extinguish fire! No, please try. Use thick copper wire or multi strands of copper wire to wind a coil whose inner diameter is slightly smaller than the diameter of the candle. There should be a certain gap between the coils. Light the candle, cover the coil made of copper wire from the flame, just cover the flame of the candle inside the copper wirethe air is not isolated, but the flame of copper wire is extinguished. Why? It turns out that copper not only has good conctivity, but also has excellent ability to transfer heat. When the copper wire covers the burning candle, most of the heat of the flame is taken away by the copper wire. As a result, the temperature of the candle is greatly reced. When the temperature is lower than the ignition point (190C), the candle will not burn
The wolf that doesn't eat sheep. You must be surprised. What's the matter? It turns out that scientists have given North American wolves a prescription for adding lithium chloride to mutton, that is, adding a chemical called lithium chloride into muttonafter eating this kind of mutton containing lithium chloride, North American wolves will suffer from dyspepsia, abdominal distension and other diseases in a short period of time. At the beginning, they obviously don't like the taste of the mutton. Later, if they are given the possibility to choose the meat, they will not eat the mutton containing lithium chloride. After many domestications, they no longer prey on lambs
