What are the benefits of buying blockchain

1. In short, blockchain is a distributed and decentralized computer technology

what is distributed and decentralized? Take marriage registration as an example. In the past, when two people got married, they had to go to the Civil Affairs Bureau to go through the formalities, and then enter the information into the computer before they could finish the legal process. What if we use blockchain technology? As long as two people agree to get married, and then release a message in the circle of friends, the process of marriage is completed, and there is no need to go to the Civil Affairs Bureau. Your friends are common witnesses, they may be distributed all over the world, but their mobile phones will help you record the information and tell others who want to know

if you want to hide the marriage information, you used to just modify the records on the computer of the Civil Affairs Bureau, but now you have to modify the records on the mobile phones of all the people who know the truth at the same time. The more people who know the truth, the less likely they are to modify it, so it is an impossible task. This is distributed and decentralized

deepen the understanding

on the network, every once in a while, a block will be generated. This block is equivalent to a network logbook, which is used to record the relevant information that happened in a period of time. When the logbook is full, a new logbook will be generated. Once the information is recorded, all participants will be informed, and everyone's logbook will be updated synchronously

these logbooks are finally connected in series, which is blockchain technology. Because of the use of cryptography technology, if someone wants to tamper with the message unilaterally, through the verification of blockchain algorithm protection mechanism, if the time point is not right and the associated information is not right, other people will not update their own record book, and the information will be invalid

therefore, compared with the traditional information storage technology, blockchain technology is more secure, transparent and irreversible

concept differentiation

blockchain is not equal to bitcoin, it is just a kind of underlying technology invented to realize bitcoin as a digital currency. Blockchain can be applied to a wider range. In addition to digital currency, it can also be applied to P2P loan, global payment, micro finance, electronic payment, remittance and other financial aspects. It can also be applied to intellectual property, election, notarization and other aspects of people's livelihood.

2. Tell you what blockchain is and what can it do

what is a blockchain? How does it work

bitcoin has become the trend of modern Internet, followed by blockchain. It is said that blockchain technology will lead to fundamental changes in Internet operation, enterprise operation and everything else

but what is blockchain? Most of us don't know much about blockchain. If you want to understand blockchain, you can read this article carefully

what is a blockchain? In the simplest terms, blockchain is a distributed ledger

to understand what this means, let's first look at its opposite: a centralized ledger. Because blockchain technology starts from finance, we will also use the bank as an example

the following is the process of our bank debit card transaction:

you can buy goods by swiping your card in the store

the merchant sends the bill to your bank to get the agreed amount

your bank will verify whether you are likely to authorize the purchase

banks remit money to businesses

finally, the bank records this information in its ledger

there are a lot of technologies involved here, but basically that's it. The last step is important - the bank keeps track of all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made

the ledger is kept, maintained and supervised by the bank. You can read it in your online bank account, but you can't change it. The bank is in full control. If it decides to make a change, there's nothing you can do

it is crucial that if hackers can access the bank's ledger, it may lead to many problems. They can change the account balance to make it look like some transaction never happened, and so on

that's why distributed ledger is so cool

blockchain network visualization

if the bank operates on a distributed ledger, each member of the bank will have a of the ledger. Whenever any member of the bank makes a purchase, they will tell all other members of the bank

each member validates the transaction and adds it to the ledger (the added record is called a "block"). This has some important benefits because there are no centralized permissions to manipulate records. Hacker access to one ledger won't be a big problem because other ledgers can easily verify it

on the other hand, it requires a lot of work. In short, the second system is blockchain (at least in the financial scenario)

as mentioned above, blockchain is a decentralized transaction list. If I send Xiaoming two bitcoins, I will send a message to everyone in the network, saying "I am sending Xiaoming two bitcoins", and they will record the transaction<

bitcoin and blockchain

let's take bitcoin as an example to illustrate

bitcoin transaction

but the transaction must be verified. This is where blockchain technology has become a bit more complex. Each bitcoin wallet (which we will complete in one second) has a public and private key

you use your private key to send transaction requests to other members of the network and confirm that you have cryptocurrency in your account. If they do, they allow transactions to register on the ledger

the mechanism of public / private key system is very complex, but it comes down to that every transaction is verifiable and secure< However, the computing cost of the whole system is very high. Everyone who updates the ledger needs a lot of authority to validate transactions and modify the ledger. This is where mining comes in. People who verify and modify use their own computing resources, and each time they get a small transaction fee

and they're using a lot of electricity to do it

in this way, each transaction will be verified and added to the ledger, and the person who performs the verification and modification will be paid. This is a reasonable system

at the same time, it is also very safe. To change a single block, you have to change each subsequent block. After all this is done, validation will fail because other copies of the chain will show someone tampered with one

how to define blockchain is a difficult problem

although the mechanism behind blockchain technology is not always intuitive, it seems that it is not too difficult to explain what blockchain is. But what we're describing here is the traditional definition

we can use this special type of blockchain for a wide range of applications;, Such as cryptocurrency, sharing medical information, sending security messages and so on. But more blockchain like technologies are being developed for other uses

for example, companies may use internal blockchains to manage problem tracking in software. Each block in the chain may represent a problem, and users can publish updates to the network. But is this a blockchain? In this case, the ledger is not public, it is only visible within the company

some people will say that this is not a blockchain

other blockchain like technologies are not encrypted. Are they still blockchain? What if it's centrally managed but uses other blockchain features? What defines the lowest level of blockchain technology? There is no consensus on these issues

what is a blockchain wallet

we usually hear people talk about bitcoin wallets, Ethernet wallets and other cryptocurrency specific wallets. But wallet technology can be used in any system that uses blockchain

a wallet is the software or hardware that "saves" your cryptocurrency. But it doesn't really have anything, it's just a place to store public and private keys. This information allows you to access the currency shown in the public ledger

the wallet is the only record of the key. So if you lose it, you will no longer be able to access your cryptocurrency

in the future of blockchain, how will it change our lives

one important thing about blockchain is that it is a public resource and no one really owns it because everyone owns it

blockchain is more than science fiction. We don't need to understand the mechanism behind this technology, but you need to understand that it may completely change our lives in the next 20 years

that sounds bold, but remember, 20 years ago, we were browsing the Internet on Netscape, using the most advanced Motorola flip phone, and buying our first DVD player. At that time, if we imagined that the computer could be held in our hands, and that we could buy a car, pay for money and watch movies on it, it would be considered a fantasy

although the impact of blockchain may not be as obvious as the Internet or as tangible as mobile phones, blockchain will effectively solve many troubles in daily life. For example, intermediary entrapment, transaction delay and so on. In our present life, middlemen can be seen everywhere. We take it for granted that they are a part of our life. If one day, these intermediaries no longer exist, you will find that the world will become a different one

imagine that by 2040, blockchain may become a mature and widely used technology. One day, you can't do without blockchain, just as you can't do without the Internet now, you will be surprised that this decentralized accounting technology has become a part of your lifestyle<

3. 1、 Property law is the gospel of property owners

Article 12 of the constitution of the people's Republic of China stipulates that "socialist public property is sacred and inviolable", "no organization or indivial is allowed to occupy or damage state and collective property by any means", and Article 13 stipulates that "citizens' legitimate private property is inviolable", "The state protects citizens' private property rights and inheritance rights in accordance with the law.". The second paragraph of Article 73 of the general principles of civil law stipulates that "state property is sacred and inviolable" Article 4 of the property law stipulates: "the property rights of the state, the collective, the private and other right holders shall be protected by law and shall not be infringed by any unit or indivial." It can be seen that the equal protection of public property and private property in the property law actually improves the relative legal status of private property and establishes the principle that private property and public property have the same civil status, which lays the foundation for the legal restoration of the universal equal civil relationship between state-owned and non-state-owned property rights, Moreover, combined with the fact that the income and wealth of Chinese citizens have generally increased since the reform and opening up, the "property owners" protected by the property law have covered the actual interests of the vast majority of the Chinese people< Second, the property law is about the legal appreciation of RMB.


in the legislative explanation and deliberation report, the property law has made positive explanations or provisions on the right to contracted management of rural land, the right to use homestead, the right to use urban commercial residential land and other major property rights involving the vital interests of the masses, It fully reflects the principle of respect and retroactive protection for citizens' real right in fact. For example, Article 149 of the property law stipulates: "if the term of the right to use residential construction land expires, it will be automatically renewed." This is not only a supplement and improvement to the unreasonable legal provisions in the past from the perspective of social stability, but also a concrete manifestation of respecting citizens' factual rights to "things" -- the vital interests of the overwhelming majority of the people are the most important social public interests, and the law, as a form of protection, should only adapt to it rather than become a system shackle, The legislative practice of property law vividly implements the basic principles of "seeking truth from facts", "respecting facts" and "people-oriented". In terms of "automatic renewal of the right to use residential construction land" only, the property law dispels the huge interest ambiguity and injects huge future economic expectations for the real estate instry, which occupies an important proportion in the national economy. In other words, through the property law, the real estate instry has the right to use residential construction land, After the expiration of the term of the right to use residential construction land, the huge rights and interests of the state owned by the original provisions are clearly retained by the original property owner according to the fact of possession of the "property", which is actually a huge, clear and legally guaranteed social investment for the real estate economy through legislation. From the above point of view, the property law opens up the operation space for the legal appreciation of the important social universal property rights, which is not only beneficial to the asset appreciation of the related instries and fields involved in the rural land contractual management right, the right to use homestead, the right to use urban commercial residential land, but also a legal appreciation of RMB< Thirdly, the economic significance of the property law is underestimated by the society.

at present, we need to further study the economic significance of the property law and look for the significant impact of the implementation of the property law on the real estate economy, financial economy and rural economy. We must pay attention to that this is an objective fact, What's more, it is an important effect that will continue to play a role in the future, or it is a far-reaching event that touches all fields of China's social and economic life. A realistic suggestion is that it is necessary for the economic instry and the general market people to explore the strategic influence from the property law in combination with their own reality, so as to obtain specific and practical strategic enlightenment
