Take advantage of the closed loop of blockchain
the biggest consensus of blockchain is to make money
there will be a process for the advancement of blockchain consensus. In the current flood and famine period, making money based on cognition and circle is still in consensus 1.0 stage. Fortunately, its size is not enough to affect the overall situation of the world economic structure, and the cost of supervision and policy intervention is low. In the large community of blockchain, more roles need to be involved, In particular, the government with service functions should not be absent, and the people in the community should not act like frightened birds, independent from the outside world
the bustling blockchain communities are not forests, but bird nests in a few trees at most. They chatter in order to grab food. Even if there is a third-class wind, everyone will be scattered. If you really want to dream of building a forest, you should bravely go down the tree, dig ditches and divert water
Let's suppose villagers Lao Wang and Xiao Li. Lao Wang borrowed some money from Xiao Li, who wrote it in an IOU signed by both parties. A few days later, Lao Wang denied the existence of borrowing money and claimed that Xiao Li forged the paper. Xiao Li can't argue because he finds it difficult to prove that Lao Wang actually owes him money
in this example, Lao Wang and Xiao Li are two nodes
now assuming the same scenario, there are many pairs of people trading with each other in the village. The only evidence for each pair is the IOU. If one party fails, it will be difficult to do so. Seeing this scene, the village head came up with a solution. He suggested using a common notebook for the whole village to record all the transactions. Due to the high prestige of the village head, the villagers unanimously decided to let the village head keep this important transaction book. Each transaction, the villagers go to the village head's home, let the village head witness and record, each transaction is written into a notebook, and then safely saved. That notebook can be called a database
because this notebook is very important, the village head locked it in the safe. However, there are always some problems. Sometimes, the village head will accidentally sprinkle ink on the paper, making some transaction records illegible. This is called a single point of failure. The thief knows that there is an important notebook in the safe of the village head's house. He tries his best to steal it. This is called hacking
until one day, the village head's son owed others a lot of money, so the village head secretly deleted his son's debt entry. In this way, the village head's son "does not owe money."
when the villagers knew this, they began to question the fairness and authority of the village head. So some people put forward a new idea:
abolish the power of the village head, which is called decentralization. Let all villagers keep a notebook, and the transaction records are copied and distributed, which is called distributed database. Therefore, if there are n people in the village, there are n notebooks, that is, n nodes. Every time there is a trade between any two people, all the people in the village get together and record it in their notebooks. And no one can cover the sky. This is called decentralization
they also decided that they would never delete the mentioned transactions from their notebooks, which is irreversible. For example, Lao Wang borrowed a sum of money from Xiao Li before, but in the twinkling of an eye, he wants to return the money. Then the transaction book will not delete the previous borrowing record, but write a new repayment record, so there are two records
next, let's try to break this rule. What if we bribe Lao Wang to change his notebook? It's not feasible, because the next time the villagers meet, they find that Lao Wang's notebook is different from everyone else's, so the villagers notice that Lao Wang may be engaged in an indescribable transaction, and decide to abolish Lao Wang's transaction record and kick Lao Wang out of the organization
What if you try to bribe all the villagers? It's too expensive
the characteristic of this model is that greedy people need to pay a lot to attack the rules. He will find it more profitable to follow the rules
a smart child in the village suggested that each transaction data be called "block" and linked into a "chain" in chronological order, which is called blockchain
1. Regularly clean the st in the computer, turn off the computer, open the chassis, use a hair dryer and blow with cold air< At ordinary times, 360 guard, Jinshan guard and other tools should be used to clean up the system garbage and temporary files generated by the Internet, and check and kill malicious
Italian software
3. The computer configuration is poor, so try to set the virtual memory as large as possible, and install anti-virus software with less resources, such as NOD32, or only one
auxiliary anti-virus software
4. Try to set the IP to static IP, which can rece the startup time of the computer
5. Don't put too many files and icons on the computer desktop, which will slow down the reaction of the computer. Try not to install the software on disk C
6. Regularly defragment the disk. Open the drive of my computer to defragment - properties - tools
select the disk to be defragmented. Open the "disk defragmenter" window - Analysis - defragmentation - the system will start to defragment

wallet circle is an app that provides blockchain data analysis services. Its vision is to become the strongest search engine in blockchain and provide users with the best search service and data experience
the wallet circle provides core data such as wallet transaction details, wallet account relationship, and token query, which can help users see the complex digital asset world through multi angle analysis and multi-dimensional display
well known wallet query, big coin holder query, big dynamic query and large transaction reminder are the highlights of the wallet circle
in view of the fact that the current situation of the coin circle is that the makers are cutting leeks crazily, and the desire of leeks to earn a little money is constantly failing, the emergence of the wallet circle and its characteristic functions is expected to change the current situation of leeks being cut crazily. Of course, the premise of preventing leeks from being cut is that the leeks use the characteristic functions of the wallet circle to keep up with the operation in time when the makers make large transactions, rather than waiting for others to cut them
in general, the wallet circle is an epoch-making proct in the coin circle and a great blockchain search software.
there are also the following instries
1, financial instry
nowadays, blockchain technology has been graally applied to various fields. The financial instry is a crucial link for the economic development of various instries and fields, and plays an important role in macro-control. The bank will no longer be a place where you have to move forward, but just a service you use. With the development of new technology, finance and Internet, all kinds of new business forms and innovations have been continuously developed, and the major cross-border competitors have emerged one after another. With the help of their own platforms, data and customer resources, they have shown their talents in the fields of payment and clearing. The payment of Alibaba and Tencent are successful cases, which makes traditional finance and banks under pressure
2, philanthropy
is a spontaneous and voluntary behavior of indivials or institutions, which does not include mandatory color. There is no interest relationship between benefactor and beneficiary. Since the reform and opening up, China's rapid political and economic development, social system reform, all of which provide a broad space for the development of philanthropy, have also set up a variety of charitable foundations, related laws are graally improved, the development speed of non-governmental charitable organizations is also accelerating. First of all, the decentralized and point-to-point characteristics of blockchain technology can rece the need for the existence of third-party institutions in the transaction process. Whether it is fund raising or material distribution, it may no longer need the participation of third parties. In the smart contract of block technology, as long as the beneficiary's conditions are set in advance in the code, the terms in the smart contract will automatically trigger execution when the set conditions are met, so as to realize the intelligent and automatic donation of charity. The high security of block technology can ensure that every transaction recorded on it is true and credible, and the whole donation system is jointly maintained by the beneficiary and the donor. The donor does not need to trust the third-party organization to realize the donation, and does not need to question whether the charitable organization conceals or deceives the public information. At the same time, the traceability of block technology enables donors to clearly find the whereabouts of the donated property. Here are some white papers on blockchain for free. You can have a look at them.
