How to correctly understand blockchain

1.

blockchain is a kind of technology, which solves the core "trust" problem in the market economy and reces the trust cost between strangers to a very low level

there is one crucial thing in the market economy, which is "trust". Without trust, no deal can be established. When you go to LAICHANG to buy vegetables, if you don't believe that the pesticide content in vegetable is up to the standard, you won't trade with that dealer; If you buy a bottle of water in a small shop, the clerk will not sell you the water if he doesn't believe that the money you give is real

the traditional small-scale peasant economy is acquaintance economy, and the transaction scale is limited to people who are familiar with each other nearby. If an acquaintance deceives you, he will lose your social relationship and damage his reputation in the whole circle of acquaintances. We believe that acquaintances are less likely to cheat us than strangers

therefore, once we are beyond the scope of acquaintances, we need to use a high cost to identify whether a stranger will cheat me and how to avoid the risk of being cheated. This situation will hinder the transaction and restrict the transaction

in addition, different races, nationalities, cultures, religious beliefs and so on will naturally have this kind of trust problem

in the market economy, why can there be so many transactions between strangers? Because of the birth of a new mechanism to solve the problem of trust in strangers

so far, the most important mechanism to solve the trust problem is the "trust intermediary" organization and mode

as long as you and strangers trust a third-party organization, the trust problem between you can be solved through this third-party organization

this third-party organization, we call it trust intermediary. Both the government and the bank are trust intermediaries

you can sell the goods you have worked hard to proce to a stranger in exchange for a stack of RMB banknotes. It's because the credit of the note issuing bank and the guarantee of the authority of the government guarantee the currency value and effectiveness of the banknotes. Otherwise, sell things, in exchange for a few ordinary paper, who would like to

in the era of global village and Internet, the people who buy your things may be strangers who will not meet and thousands of miles away. Trust is lower, so Alipay assumes the role of trust intermediation. Buyers first pay the goods to Alipay's account. When they receive the goods, they confirm that they are OK, then they agree to sell the goods to the seller. Taobao and other e-commerce have been booming rapidly in just over ten years

trust intermediary is in a central position in the transaction system. All transactions should solve the trust problem through it

However, the cost of trust intermediary itself is often huge

as a trust intermediary, how much transaction tax does the government charge each year? What is the most profitable instry? Financial services. The annual profits of Alipay's ant suit are over ten billion. p> What does this mean? Both sides of the market actually pay a huge trust cost

if there is any way to cancel or greatly rece the trust cost, the transaction cost of the general public can be reced, and the profits can be greatly increased

so in the Internet era, blockchain technology is on the stage

it allows the trading party to get rid of the intermediary, solve the problem of trust among strangers, and greatly rece the cost of trust

the blockchain can be expanded on a large scale, the data is open and transparent, the data of each client is consistent, and even if some clients are destroyed, the data security will not be affected. These highly reliable technical features can solve the trust problem of strangers with low cost

this technology can be extended to all fields that can be digitized, such as digital currency, payment and clearing, digital bills, proof of rights and interests, credit reference, government services, medical records, etc

in the medium and long term, blockchain will be a revolutionary technology, which will bring about great social changes like the existing Internet, and has great investment value and money making opportunities

in the future, the companies that can combine blockchain with different scenarios to promote applications may be the next group of bat, the next Google, Microsoft and apple

as the first practical application of blockchain technology, bitcoin has been widely accepted and used all over the world. Millions of users and tens of thousands of merchants have accepted the payment of bitcoin as a digital currency, and the exchange value of bitcoin as a currency is growing. Even e to the consensus that the total amount is fixed and the long-term value is bullish, bitcoin has become a hedge asset similar to gold, and the price has skyrocketed

2. Buy one or two books about blockchain, and you will have a general understanding of blockchain technology and development prospects. But we should also pay attention to real-time dynamics. China has done a good job in this field. There are weekly, monthly and other instry analysis reports, which are relatively authoritative in China.

3.

blockchain is a decentralized distributed ledger database . The advantage of this distributed ledger is that buyers and sellers can trade directly without any intermediary. Everyone has a backup, even if you lose this, it will not be affected

{rrrrrrr}

extended data:

blockchain application field

1, financial field

blockchain has potential huge application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment

2. The Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain

3. The data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision

4. In the field of insurance

in terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized

4. You can use the battery manager of Tencent mobile phone manager to maintain and manage the battery
Tencent battery manager will intelligently rece the CPU frequency and keep the minimum power consumption
in normal use, Tencent battery manager will maintain a stable CPU frequency,
keep the best power saving state without affecting the experience; When playing games,
battery manager will give full play to the powerful performance of CPU and improve the fun of playing games.

5. What app? Now many of them are routines

6. We need to look at the mining income according to the model of the graphics card, and then use the income to look back at the cost time. If it is a low-end graphics card, it may not be able to be found in my life

7. The simple one is that e-money is not the traditional cash, but the transaction of data and data. No matter how you transfer or how you trade, the cash is in the bank, and the bank's money is invested, which is very helpful to the economic development and the dominant direction of money in the future. However, there are also shortcomings. E-money is very easy for the financial sector to cause economic bubbles. The same financial effect is doubling the financial effect. That is to say, funds have a circulation function in numbers, but in terms of banks, the cash they are holding has an additional effect on the circulation of electronic money in the society. It will inevitably rece the circulation of cash and RMB in the market, which will easily lead to inflation and price rise.

8. From the perspective of development, the biggest problem we are facing in the proction and life of the whole Chinese economy is credit. The slogan of integrity has been chanted for so many years, but the integrity of the whole society is getting worse and worse. Now not only private enterprises, but also some state-owned enterprises have begun to breach the contract. How to prove that "your mother is your mother", China claims to be the first country in the world in terms of GDP by PPP, but e to the lack of integrity, it has added huge proction and living costs. As a new technology paradigm, blockchain will bring more proctivity than everyone imagined. We regard blockchain as three layers. The first layer is technology, ledger, cryptography and authentication mechanism. The second layer is the business model, which is based on the business ecosystem reconstructed by blockchain. The third is philosophy, philosophy. The revolution of any kind of proctivity will inevitably be abstracted and sublimated into a metaphysical proction relationship, and so will blockchain. Blockchain technology and its application have the following characteristics: distributed, flat, mandatory trust, collective maintenance, reliable database, open source, privacy protection and so on. Together, these technologies will have a certain impact on many concepts and business models that we are used to. The underlying framework of laikelib blockchain is similar to Ethereum, with the idea of decentralization as the core, and is committed to building an open credit value circulation network to make credit value widely distributed.

10. See if your clothes have the logo of bmw lifestyle. Some of them are the clothing brands of BMW, but they are not directly proced by BMW. They are looking for the OEM of baozi clothing

without that logo, it would not be BMW's brand, it would be a typical fake brand close to a big brand.
