Efficiency of security decentralization
@ block chaining
to make complaints about the center is code open source, you can check, ensure that they will not install viruses and upload your personal data. p>

it doesn't matter if the wallet goes out of business, just export the private key and save it to other wallets

the exchange transfer fee is about 30 yuan per time, and the transfer from your wallet is only a few cents per time
centralization has the advantage of centralization, which should not be too one-sided.
e to the need to link transaction data and wait for miners to pack and broadcast transaction confirmation, the transaction speed of decentralized transaction is slow. The operation steps of decentralized trading platform are relatively complex, and the use threshold is higher. When it comes to the transaction of different blockchain assets, such as bitcoin and Ethereum, it needs more complex cross chain technology, and many decentralized trading platforms can't realize it, so the supported transactions are less than the centralized trading platform

billion in 2020. Overall, with the acceleration of the development of the Internet of things, the number of networking devices will be several times more than the existing mobile Internet
according to the data of the analysis report on market demand and investment opportunities of China's Internet of things instry segments issued by foresight Instry Research Institute, the scale of the global Internet of things market will reach US $200 billion in 2025; The number of Internet of things will reach billions, benefiting the whole value chain; The application of the Internet of things in various instries is deepening, giving birth to new technologies, which is concive to the transformation and upgrading of traditional instries
at present, the Internet of things application scenarios have formed a large particle (annual demand is more than 10 million) market, mainly in the fields of intelligent meter, mobile payment, smart car, smart grid and so on. Growth in these areas has led to major growth in the instry
the Internet of things extends the service scope of mobile communication, from people to people communication to things and people to things intelligent interconnection, which makes mobile communication technology penetrate into a broader instry and field. Facing 2020 and the future, mobile medical, Internet of vehicles, smart home, instrial control, environmental monitoring, etc. will promote the explosive growth of Internet of animals applications, and hundreds of billions of devices will be connected to the network to realize the real interconnection of everything;, And create an unprecedented scale of emerging instries, for mobile communications to bring infinite vitality. At the same time, massive device connections and diversified Internet of things services will also bring new technical challenges to mobile communications.
As we all know, adolescent children are rebellious and difficult to manage. A lot of teachers and parents, nagging, make children tired, do not say, also did not play any effect. I have two practical "magic weapons" to share with you. It's also called "make rules first"; It's also called "increasing the cost of making mistakes.". Today I will focus on the first one
the class rules of our class, for your reference
after setting up the rules, we should be fair to things and not to people
the most important point for a head teacher to win people's hearts is fairness. A child's good performance does not mean that he will not make mistakes. No matter who he is, in my class, it doesn't matter whether his performance is good or bad, whether his parents have the strength or not, whether he is a boy or a girl, it doesn't matter. What we want is fairness. So, in my class, the children have a saying: "what is said in class 13 is not the teacher, not the parents, not the classmates, but the class rules formulated by the teacher and the children.". Once upon a time, two children quarreled. One child opened his mouth and said dirty words. They came to me to judge. I only asked them: "you say, according to the class rules, how to deal with?" They bowed their heads and said what to do. The solution to the problem is so simple. The rules established in advance are very important, and the fair implementation is even more important
some advice for family ecation:
the most useless ecation in the world is nagging. You will feel tired and your children will feel even more tired. Once the rules are made and the child violates them, just ask him, "what do you think we should do according to the rules we have agreed in advance?" In a simple sentence, children can be aware of their mistakes
adolescent ecation needs patience, but also needs methods. Proper methods can get twice the result with half the effort. The final beneficiary will be the children
1. Efficiency is different: the efficiency of decentralized network is higher than that of centralized network, but conversely, the security of centralized network is higher. On the whole, centralized network is suitable for high security applications
2. Different characteristics: centralized network means that each time two client computers communicate with each other through the server. The decentralized network is the initial need to go through the server, later communication does not need the server
3. Different costs: the characteristics of collective maintenance of blockchain can rece a lot of costs. The centralized network involves the maintenance, confidentiality, operation and so on of many systems, which must require a lot of human, financial and material resources. These things do not exist for the decentralization of blockchain, so they can save a lot of costs

precautions:
in the aspect of blockchain governance, an interesting trend recently is the re emergence of online virtual currency holder voting as a multi-purpose decision-making mechanism. Sometimes the vote of the coin holder is used to decide who runs the super node of the network (e.g. dpos in EOS, Neo, lisk and other systems), sometimes the protocol parameters are voted (e.g. the upper limit of Ethereum fuel supply), and sometimes the vote and direct application of approval (e.g. tezos) protocol upgrade are also concted
in all these cases, voting is automatic, and the protocol itself contains all the logic needed to change the verifier set or update its own rules, and automatically responds to the voting results
