3. What is the blockchain?

What is the blockchain?

What is the blockchain? Many people have no idea what the blockchain is. , is not very clear, and some people have even never heard of it. In fact, blockchain is a common one. I have compiled relevant information about what blockchain is for everyone.

What is blockchain 1

Speaking of blockchain, we have to mention its twin brother-Bitcoin.

Go back in time 11 years ago. On November 1, 2008, the world was shrouded in the huge shadow of the financial crisis. That day, a mysterious geek who called himself "Satoshi Nakamoto" sent a group email.

Attached to the email is a paper titled: "Bitcoin: A Peer-to-Peer Electronic Cash System."

Satoshi Nakamoto said in the email that he is working on a new electronic cash system that is completely peer-to-peer and does not require any trusted third party. About half a month later, Satoshi Nakamoto released the source code of the Bitcoin system non-stop.

On January 3, 2009, an interesting invention turned out. Satoshi Nakamoto generated the first Bitcoin block on the server, which is the so-called "Bitcoin genesis block". Since then, the Bitcoin system has officially opened.

Having said that, you might as well stop and think about how we conduct cash transactions in real life.

Suppose you borrow 10,000 yuan from a friend and promise to pay it back in one month. You may choose to repay the loan by bank card transfer. The bank is responsible for deducting 10,000 yuan from your deposit account and adding 10,000 yuan to your friend's deposit account.

Here, the bank is the institution responsible for keeping accounts. The underlying reason why you choose bank transfer is that you believe it is more reliable and will help you transfer 10,000 yuan to a friend.

However, in the digital world, inventing a currency is another matter.

The hero behind the Bitcoin game

First of all, Satoshi Nakamoto hopes to conduct peer-to-peer direct transactions, bypassing the third party of the bank. This problem is easy to solve. Then there will be no banks. Users will issue their own currencies through a unique mechanism and trade directly with each other.

But this brings another problem. There is no bank as a reliable intermediary responsible for accounting, and users do not know each other. How to ensure that no one cheats during transactions?

For example, in the digital world, electronic files can be easily copied. 10 yuan of digital currency turns into 100 yuan by copying and pasting it with the mouse 10 times. Isn’t it a mess?

To solve this problem, we need to provide a mechanism for everyone to trust each other.

The method adopted by the Bitcoin system is to record all transaction processes openly and transparently in chronological order. These records are permanent and cannot be tampered with. This way you won't be able to do anything sneaky.

With these mechanisms, the Bitcoin system operates successfully.

This system stores data in units of data blocks, which are blocks. Approximately every 10 minutes, new blocks will be added. Each block records the detailed transaction process of Bitcoin and is timestamped. Different blocks are connected in chronological order through a certain algorithm, which is a chain.

Together, they are called ""Blockchain".

In this way, the blockchain took root with the birth of Bitcoin. If Bitcoin is the star that attracts attention on the stage, the blockchain is responsible for the underlying The hero behind the scenes who technically provides a trust mechanism.

Brand new changes in accounting methods

Although behind the scenes, the talent of blockchain was quickly discovered.

< p> In professional terms, blockchain is a distributed ledger technology. To understand it, let’s take the simplest example.

Assume that your home keeps accounts like this : You, your father, and your mother each have an account book. You each record your own expenses, and you calculate the total household expenses together at the end of each month.

But your father likes to buy cigarettes, your mother likes to stock up on cosmetics, and you like to buy snacks. You may all intentionally or unintentionally omit a few entries, and sometimes make corrections in the account book. Therefore, when you check the account book at the end of the month, it will always be slightly different from the actual expenditure of the family.

In order to change this situation, you will re- You bought a new account book. You, your father, and your mother will use the new account book to keep accounts, remind each other, supervise each other, and check each expense together.

At the same time, you also agreed that once the expenses are verified, Once you write it down clearly, you are not allowed to alter or delete it. After trying it for a few months, you found that this common ledger is much more consistent with the actual expenses at home.

Blockchain is the second accounting method. . The little story above tells us that it has at least these major advantages or benefits.

First of all, it is decentralized. The database that was previously maintained by one party has become jointly maintained by multiple parties. Everyone relies on Consensus writes the data together, and no one can control the data alone.

Secondly, it allows everyone to change from keeping separate accounts to jointly keeping accounts, which brings consistency and openness and transparency to the data.

p>

In addition, the blockchain only allows data to be written, not deletion or modification, which can prevent data from being secretly tampered with.

Mutual trust between strangers

In reality, many scenarios are much more complicated than how to keep accounts at home. Moreover, many aspects of financial transactions and business processing are mostly operated by strangers. How can we make everyone trust each other?

This is the turn of blockchain to show its talents. Don’t forget, it can provide a mechanism for everyone to trust each other from the underlying technology.

For example, when you usually go to the vegetable market When buying things, you may worry about the safety of fish, shrimps and vegetables. Some companies see business opportunities and move the data of farmers and fish ponds to the blockchain. In this way, you can know which fish pond the fish you buy comes from. You will eat with more confidence.

For another example, links to fundraise for seriously ill patients often appear in Moments. When donating, you may have some concerns: Is the patient's condition real? Can the donation really be delivered to the patient? In?

ForIn order to eliminate these concerns, some Internet charity organizations use blockchain to allow you to clearly view the steps for using your donation. If the review finds that the patient's condition is not true, the blockchain system will automatically return the donation to your account.

In the future, what changes can blockchain bring to our lives?

It is conceivable that when blockchain is widely used in various fields of society, it will become an important infrastructure in the information age and can solve many of the headaches that currently cause us.

For example, blockchain will allow countless islands of information to be "chained" together. When seeing a doctor, there is no need to repeat the examination just because you change hospitals. Entrepreneurs do not have to go to multiple departments to go through a procedure; many transactions no longer need to be done. Third-party guarantees are required, consumers no longer have to worry about non-refundable deposits, and creators do not have to worry about their works being stolen but getting nothing...

What is blockchain 2

From an academic perspective, blockchain is New application models of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. Blockchain is essentially a decentralized database.

Many people still don’t understand this explanation, so let me make a simple metaphor.

Hypothetical situation: Suppose you have a ledger at home and you are asked to keep accounts. In the past, your parents gave you your salary and asked you to record it in your account book. If you are greedy and want to buy something delicious in the meantime, the record in the ledger may be less than ten yuan.

This is just an example. I believe that when we were children, everyone probably wanted to take some money from their parents’ pockets to spend.

Ways to use blockchain to solve problems:

If you use the whole family mobilization method to keep accounts, the above-mentioned problems will not exist, because you are keeping accounts, and your father They are also keeping accounts, and your mother is also keeping accounts. They can all see the general ledger. You can't change it, and neither can your parents. So your father who wants to buy cigarettes and you who want to eat have nothing to do.

Functional "blockchain"

It can not only record every transaction, but also can be programmed to record almost everything of value to mankind. Things: birth and death certificates, marriage licenses, title deeds, degrees, financial accounts, medical history, insurance claims, ballots, food sources, and anything else that can be represented by a code.

Each block is like a hard disk, which saves all the above information and then encrypts it through cryptography technology. The saved information cannot be tampered with.

Every 10 minutes, the blockchain system will check all data generated during the period (such as transaction records and records of when the block was edited or created, etc.) and store these data in a new area. On the block, this block will be connected with the previous block to form a chain. Each block must contain relevant information from the previous block to be effective.

Characteristics of blockchain

1. Exceptionally safe:

Unlike centralized databases owned by companies or government agencies, blockchain is not controlled by any person or entity, and the data is completely replicated (distributed) on multiple computers.

Unlike centralized databases, there is no single entry point for attackers, and data security is more guaranteed.

2. Non-tamperability:

Once entered into the blockchain, no information can be changed, and even the administrator cannot modify this information.

Once something appears, it cannot be changed. This attribute is of great significance to the changeable and ever-changing online world that humans currently live in.

3. Accessible:

All nodes in the network can easily access information.

4. No third party:

Because the blockchain is decentralized, it can facilitate peer-to-peer transactions, so whether you are trading or exchanging funds, there is no need for a third party of approval.

Blockchain itself is a platform.

Blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Currently, each is keeping its own account.

Since there is no centralized intermediary agency, letting everything run automatically through preset programs can not only greatly reduce costs, but also improve efficiency. And since everyone has the same ledger, it can ensure that the ledger recording process is open and transparent.

Blockchain technology is the underlying technology of Bitcoin. Without the operation and management of any centralized organization, Bitcoin has been running very stably for many years without any problems, so some people have noticed its The underlying technology abstracts the Bitcoin technology and calls it blockchain technology, or distributed ledger technology.

According to a report released by Santander, Spain's largest bank, if all banks around the world use blockchain technology internally around 2020, they will save approximately US$20 billion in costs per year. Such data is enough to illustrate the tremendous changes and breakthroughs that "blockchain" has brought to the traditional financial field.

Cloud computing is usually defined as providing dynamic, easily scalable and often virtualized resources through the Internet, but it is often a centralized organization that provides a cloud computing platform. The network composed of blockchain generally does not have a specific organization, so blockchain is closer to the definition of a distributed computing system and is a type of distributed computing.

The future development and application scenarios of blockchain

1. Digital identity

Many people will encounter "prove that my mother is me" when applying for various certificates. "Mom" dilemma, with blockchain, you no longer have to worry about it.

It turns out that our birth certificates, real estate certificates, marriage certificates, etc., need a central sectionOnly then can everyone admit it. Once cross-border, contracts and certificates may become invalid because of the lack of a global central node.

The non-tamperable nature of blockchain technology has fundamentally changed this situation. Our birth certificates, real estate certificates, and marriage certificates can all be notarized on the blockchain and become things trusted by the world. , of course, it can also easily prove "my mother is my mother".

2. Health care

Simply put, it is to use the blockchain to establish a universal record repository with timestamps, so that different databases can extract data information.

For example, when you go to see a doctor, you don’t have to change hospitals for repeated examinations, and you don’t have to worry about reimbursement for medical insurance, which can save time and expenses.

3. Travel consumption

For example, we often use apps such as Ctrip and Meituan to find and place orders for hotels and other services, and each platform gets commissions from them.

The application of blockchain is to remove middlemen and create a secure, decentralized way for service providers and customers to connect and trade directly.

4. More convenient transactions

Blockchain can make payments and transactions more efficient and convenient. The blockchain platform allows users to create smart contracts that become active when certain conditions are met, meaning that automatic payments can be released when both parties to a transaction agree that their conditions are met.

5. Strictly control product quality

If you buy an apple, with blockchain technology, you can know the entire process from the production of the fruit farmer to the circulation link. Among them are government regulatory information, professional testing data, enterprise quality inspection data, etc. A smart supply chain will make the food we eat and the products we use every day safer and give us more peace of mind.

6. Property rights protection art

The creator puts his work on the blockchain, and if someone uses his work, he can immediately Know. Corresponding royalties are also automatically paid to the creator.

Blockchain technology not only protects copyright, but also helps creators sell their works to consumers better and more directly, without the need for the assistance of distribution companies.

What is blockchain 3

Advantages of blockchain

Decentralized, it does not require the intervention of a third party and enables point-to-point transactions, coordination and collaboration. Because the data is distributed in various nodes through algorithms and has a unique verification mechanism, no one organization or individual can control the global data. Since it is distributed in various nodes, any node stopping work will not affect the entire system. Operation, this decentralized network will greatly improve data security. The data in the system is jointly maintained by various nodes with maintenance functions.

Openness, the systemIn addition to the private information of all parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface, so the entire system information is highly transparent.

Where does blockchain come in?

Blockchain is an open, transparent, decentralized and secure technology. This technological revolution is applied to the Internet. For data-sensitive fields such as medical care, public opinion supervision, and ecological testing, it can prevent data from being tampered with and ensure the authenticity of the data.

In short, blockchain is not just a way of virtual currency, its advantages will play an important role in many industry fields

4. What is cloud currency

Yuncoin is a common virtual currency in the value-added service market of Yuncaijing.com, which can be used to exchange for various value-added services provided by Yuncaijing.com, such as customized real-time information services, seat tracking services, etc.

5. What does blockchain mean and what are its main uses

In recent years, a hot word has appeared frequently on the Internet, that is "blockchain". This word gives people a very noble and very It feels awesome, but many people don’t know what blockchain means? And what are the main uses of blockchain? Let’s take a look at the relevant content that has been issued.

Blockchain Blockchain is actually equivalent to a disintermediated database, which is composed of a string of rubber data blocks. Each of its data blocks contains information about a Bitcoin network transaction, which is used to verify the validity of the information and generate the next block. In other words, blockchain is essentially a decentralized database.

In a narrow sense, blockchain is a chain data structure that combines data blocks in chronological order and is cryptographically guaranteed. Distributed ledger that cannot be tampered with or forged. Broadly speaking, blockchain is actually a distributed infrastructure and computing method that is used to ensure the security of data transmission and access.

In addition, the blockchain is composed of six infrastructures: data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Regarding its role, blockchain is mainly used to solve the trust and security issues of transactions. The above is the relevant content about the meaning and function of blockchain. I hope it can help friends in need.
