What is the blockchain for?

What is the blockchain for? There are many things in the world that touch our knowledge blind spots, and blockchain is one of them. However, blockchain is often mentioned, so we also need to understand blockchain. Next, I will take you to understand what blockchain is for.

What is blockchain for? 1

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a disintermediated database. As the underlying technology of Bitcoin, it is a series of related cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

Applications

1. Art industry

Ascribe allows artists to use blockchain technology to declare ownership and issue certificates. Numbered, limited-edition pieces can be used in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.

2. Legal industry

BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.

3. Development industry

Colu is the first company to allow other companies to issue digital assets. Their ability to "tokenize" various assets has impressed many people. While the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu's tokens can be configured in various states and types, be able to leave and return to the system, and When storing data on the blockchain is too large, the data can be stored on the BitTorrent network.

4. Real estate industry

They plan to modernize the entire industry chain process and solve various problems faced by everyone involved in real estate, including the naming process, land registration, Agency intermediaries, etc.

What is blockchain

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. It is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods.

Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information, prevent counterfeiting and generate the next block. It is a set of data storage mathematical architecture constructed in a way that is almost impossible to forge or tamper with, and can be used to store all kinds of valuable data.

The Cyberspace Administration of China issued blockchain information service management regulations on January 10, 2019, which will take effect on February 15, 2019.

What is the blockchain for 3

Before talking about the blockchain, let’s talk about the Internet. The Internet is now an indispensable part of us and is closely related to our lives. First of all, the biggest disadvantage is It can only transmit information. The key is that the information data on the Internet can be set artificially. For example, it is often said to browse Weibo and so on. Secondly, there are bugs in the Internet environment, which means that there cannot be equality in data ownership. This is to say that there are some disadvantages of the Internet.

Putting aside what blockchain is, let’s talk about the Internet and blockchain. Blockchain and the Internet are a parallel relationship, and they can also be a continuation of each other’s complement. So what is a blockchain? A blockchain is actually a series of data blocks that are associated using cryptographic methods. Simply put, there are many data blocks connected in a certain time sequence. It can also be said that a blockchain is a ledger. , but the account book is different from the ordinary computer account book. The blockchain account book is jointly kept by all computers in the world. The biggest feature is that it cannot be tampered with.

What can the blockchain do?

1. Machine trust

In professional terms, it is because of the blockchain The tamper-proof nature of technology fundamentally changes the centralized credit model. Build lowest-cost credit with code. In other words, as long as the code on the blockchain is executed, there is no need to worry about the possibility of stopping midway. Creating a new era of machine trust. Blockchain is expected to lead us from personal trust to the era of machine trust. In other words, his trust cost is close to zero.

2. Value transfer

The Internet can only transfer information but cannot realize the value of information. In other words, the transition from the information Internet to the value Internet will Some fundamental changes occur. Blockchain transfer will be more convenient, while also achieving low-cost transfer of value.

3. Smart contract

This is also one of the most obvious features of the blockchain. When a pre-programmed condition is triggered, the smart contract begins execution and cannot be interrupted, deleted, or modified by any party.Wait until the contract ends instead.

4. Token mechanism

Token mechanism is actually a form of value circulation. Through the tokenization of physical or virtual assets, it can work directly through the network. Mainly There are cost reductions, time savings and crossing borders. It can also be understood as proof of rights and interests. Xunlei and "LinkToken" all belong to the "Token" blockchain.

Blockchain characteristics

It has the characteristics of decentralization, anonymity, autonomy, openness, traceability, non-tampering, collective maintenance and no need for recognition. At present, we often talk about the following types of blockchains: public chain, private chain, alliance chain and side chain.

The application value of blockchain

1. Blockchain information security

Information security is one of the biggest features of blockchain, such as Facebook some time ago The leaks brought some negative social impacts. On May 8, Facebook established a blockchain department to study how to use blockchain technology.

2. Underlying technology

This is one of the most imaginative and core technologies of the blockchain. This is a highly professional academic. Let’s give a simple example. , the most famous project of this underlying technology is Ethereum.

3. Bass service

This is a series of services provided by using data generated by the blockchain, such as queries, etc. In terms of network and Tencent, both have launched their own Bass services. .

Where are the five blockchains mainly used?

At present, relatively mature areas include blockchain + medical care, blockchain + Internet of Things, blockchain + culture and entertainment, blockchain + public welfare, etc.

B. What is blockchain

What is blockchain? What changes will it bring to your future life?

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods related to each other. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

In fact, the original English version of the Bitcoin white paper does not appear in the word blockchain, but uses chain of blocks. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

State Internet Information Office 20The "Blockchain Information Service Management Regulations" were released on January 10, 2019, and will come into effect on February 15, 2019.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-transformable. Fake distributed ledger.

So in conclusion, this is undoubtedly a new technology that changes life. In the future, the production activities of the entire society will be carried out with blockchain as the underlying logic. Many things We all have it at our fingertips, and with the integration of artificial intelligence and big data, we can easily handle things that may seem cumbersome now, such as some securities market transactions and intelligent matching of financial management activities.

To put it simply, blockchain is a network computing center that integrates people, property, machines, and goods, and packages them into a whole; putting it on an infrastructure to run.

C. What is the concept of blockchain? Is blockchain a scam? The most complete explanation of blockchain

What is the concept of blockchain?

On October 25, 2019, the country advocated the development of blockchain. Overnight, the blockchain concept became popular.

However, many people are hearing about blockchain for the first time.

So, what is blockchain?

Let’s take a look at it from an academic perspective:

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transactions. Information, used to verify the validity of its information (anti-counterfeiting) and generate the next block.

In fact, blockchain is essentially a decentralized database.

Is blockchain the same as Bitcoin? Blockchain is not Bitcoin. The first application of blockchain is Bitcoin.

What are the characteristics of blockchain? Now let’s take a look at several characteristics of the blockchain:

1. Decentralization:

The most important feature of the blockchain is decentralization, and the blockchain system is different Based on a centralized database, it is not controlled by any person or entity. Through distributed storage, data is completely copied and distributed on multiple computers, and each node realizes information self-verification, transmission and management.

2. Non-tamperability:

The blockchain system also has the characteristics of non-tamperability. In the blockchain system, each node is the center and no information can be changed, not even the administrator can modify this information. districtThe consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. This situation is basically impossible, thus eliminating the possibility of fraud.

3. Publicity:

In a blockchain system, all nodes in the network can easily access information. The foundation of blockchain technology is open source. In addition to private information being encrypted, blockchain data is open to everyone. Anyone can query blockchain data and develop related applications through public interfaces, so the entire system information is highly transparent. .

4. Independence:

Because the blockchain is decentralized, it can facilitate peer-to-peer transactions, so there is no need for a third party whether in transaction or exchange of funds. of approval.

Based on consensus specifications and protocols, the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without any human intervention.

Let’s assume an environment: 6 people live in dormitory 188 of the university

There is a ledger in the dormitory for Xiao Li, who is good at calculation, to keep accounts.

In the beginning, when the dormitory sold paper boxes or bought some public items, Xiao Li would record them in the ledger. If Xiao Li wanted to enrich himself and made false accounts, there would be less money in the account books, but no one would know.

After all, there is already a general ledger room, who would have nothing to do to keep track of the ledgers?

However, one day, because Xiao Li took more, there were obvious errors in the account book. Now, he could no longer hide it, so Xiao Li had to admit his mistake and make up the money.

So, how to solve this problem?

If blockchain is used to solve the problem:

Everyone in the dormitory takes out a ledger, and every time a transaction occurs, everyone records it in their own ledger. , such problems will not arise, because everyone is keeping accounts and can see the transaction records and final results on the ledger.

Xiao Li can’t change, you can’t change, and neither can your lower bunk. No one can change it.

This is because the previous accounting model was a centralized accounting model, and the current accounting model is a decentralized accounting model, where everyone is the center and everyone is the accountant.

If someone wants to change it, it will obviously be ineffective if they only change the data on their own account book, unless they bribe three people.

So, is blockchain a scam?

With the emergence of great benefits of blockchain, in a short period of time,The price of blockchain-related assets has soared, and ordinary investors are becoming more and more interested in blockchain, and criminals are also taking aim at this. There are some criminals who wear the gorgeous cloak of "blockchain" and use the blockchain to commit fraud or issue digital currencies without permission, leading many people to think that the blockchain is a scam.

But in fact, it is not. Blockchain is just a technology. If it can be used well, it will benefit the public and promote the development of the industry.

In particular, the application of blockchain is very wide and can be applied to almost everything of value to human beings.

Medical field: For example, when you go to the hospital for medical treatment, you can directly check the previous medical treatment in your own database, which greatly saves medical resources and saves medical expenses for repeated examinations.

Food traceability: Do you know where the food on your table comes from? Which logistics team is transporting it? This information can be tracked using blockchain. It can provide us with a single source of truth.

Supply chain application: For example, when we buy a product on a certain product, it leaves the factory, goes to the distributor for logistics turnover, goes to the seller's store warehouse, and then reaches the consumer's hands. During these processes, if something goes wrong, only you will know about it, and others, especially consumers, will not.

Well, this is where I introduce you to the relevant knowledge about the concept of blockchain. I hope it can be helpful to you.

D. What is the concept of blockchain? Read it in three minutes!

On October 25, 2019, Xinwen Broadcast sent a very important signal: the country must vigorously develop blockchain. After that, blockchain has become an Internet celebrity, and the figure of "blockchain" is floating in the streets and alleys. In fact, many technology companies have already deployed blockchain technology.

Although blockchain is very popular, many people do not know much about blockchain.

What is blockchain?

Let’s first take a look at how Du Niang explained it. Network display: Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.

Why is blockchain called blockchain?

The blockchain is linked by blocks one by one, and the blocks are storage units one by one, which record the communication information of each block node. The blocks are much like the records of the database. Writing data every time creates a block. With the expansion of information exchange, one block continues with another, and the result is called a blockchain.

What are the characteristics of blockchain?

Blockchain mainly has the following characteristics::

1. Decentralization: In the blockchain system, every node has equal rights and obligations, and there is no central control. Decentralization has well established trust relationships with each other. Although there is no central management organization, people can collaborate with each other and trust each other. This mainly applies blockchain distributed ledger technology.

2. Openness: Blockchain data is open to everyone. Except for some encrypted information that is not open, everyone can check the data here.

3. Independence: The entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without any human intervention.

4. Security: Blockchain has a certain degree of security and cannot be tampered with. Because everyone in the blockchain system has the same ledger, if someone wants to tamper with it, it is possible to forge a non-existent record only if they control more than 51% of the accounting nodes. Of course, this is basically impossible. This is mainly due to the core technology of the blockchain: the consensus mechanism. The consensus mechanism has the characteristics of "the minority obeys the majority" and "everyone is equal".

5. Anonymity: Many people think that if the blockchain is so open and transparent, will we lose privacy? In fact, no, although the transaction information in the blockchain is open and transparent, the identity information of the account is encrypted and can only be accessed with authorization.

Now let me tell you a story to help you better understand the blockchain.

There are three people in the family, mom, dad, older brother and younger brother. Last year, my father was in charge of the family's account books. He was responsible for all the family's income and expenses alone.

However, on the day of Double Eleven, my mother, who has always been frugal, wanted to buy herself a beautiful piece of clothing on a certain online store. When she checked the account book, she found something was wrong. It stands to reason that except for some money deposited in banks and financial management, the whereabouts of the daily consumption money at home are all in this account book, but no matter how you look at it, it is wrong. Some consumption is clearly not recorded, but is recorded.

Later, my father took the initiative to confess that he couldn’t help but buy a pack of cigarettes.

Later, my mother changed her strategy and the whole family kept accounts. Everyone recorded their monthly consumption expenditure in their own account books. Whenever there was a transaction or consumption at home, my mother would shout, "Book it," and everyone would record the transaction in their own books. This is the decentralized accounting model, where everyone is the center and everyone has a ledger.

The previous accounting model for dad was centralized accounting. If dad wanted to do something alone, it would be difficult for anyone to see it. The decentralized accounting model has solved the problem of centralization very well. Disadvantages of accounting,It would be very difficult for Dad to tamper with the account books.

For example, if dad wants to take some money from the ledger and secretly buy cigarettes, the amount of money is limited, and if he wants to take the money, he has to change the ledger, but he only tampered with his own ledger. No, he had to change the accounts of three people including himself. And this is undoubtedly more difficult than reaching the sky.

So, many times my father had the idea of ​​smoking, but he had no choice but to give up the idea due to the current situation.

Are blockchain and Bitcoin the same thing?

In fact, blockchain and Bitcoin are not the same thing. It is just the underlying technology of Bitcoin. Bitcoin is the first digital currency applied by blockchain.

In 2008, Satoshi Nakamoto first proposed the concept of blockchain. In the following years, it became a core component of the electronic currency Bitcoin, serving as a public account book for all transactions. Blockchain was first applied to Bitcoin.

The origin of blockchain is to solve the problem of trust, and one of the most successful applications of blockchain is digital currency. Bitcoin is arguably the most successful application of blockchain so far.

What are the applications of blockchain?

The application of blockchain is actually very wide. In addition to digital currency, the future applications of Bitcoin are still very extensive. Blockchain technology has been widely used in different industries. Such as product traceability, copyright protection and transactions, payment and settlement, Internet of Things, digital marketing, medical care, etc., promoting different industries to quickly enter the "blockchain+" era.

1. Payment and clearing: Blockchain can abandon the role of transit banks, realize point-to-point payment, reduce transit fees, and accelerate fund utilization.

2. Product traceability: For example, if we buy a piece of clothing on a certain store, we can see the past and present life of this piece of clothing.

3. Securities trading: Traditional securities trading requires the coordination of four major institutions, which is inefficient and costly. Blockchain technology can independently complete one-stop services.

4. Supply chain: Introducing blockchain technology into the supply chain system, synchronizing information within the system can control all links, better complete division of labor and collaboration, and facilitate subsequent accountability.

5. Intellectual property rights: With copyright on the chain, our photographic works, musical works, literary works, etc. will become our information, and the ownership of the information will be confirmed and become our property.

E. 2018 is the first year of blockchain, so what is blockchain in 2019?

2019 is the first year of blockchain breaking financial monopoly
From Wired Industries from television companies to retail companies are scrambling to hold on to what they consider their most precious possession: their monopoly. Conventional wisdom holds that “if youIf you control the entrance and channels, consumers will have almost no choice. ”
However, we are seeing companies like Netflix and Amazon disrupt the original landscape and provide more choices for our lives. Likewise, in the field of digital currency and finance, some of the largest financial institutions are facing facing serious challenges.
It is expected that decentralized business and demand will rise in 2019, and I think this will provide more opportunities for already successful blockchain companies. At the same time, this opportunity also means risks. If Just like in 2018, if blockchain company founders or entrepreneurs promise too much and the project is suspected of being exaggerated, they may be discredited and lose their first-mover advantage.
Asia is one step ahead
For decades, the world’s largest financial institutions have controlled most of the global economy’s financial system.
However, blockchain companies have begun to gain a level playing field by accessing banking and real-time payments. In 2019 In 2019, in addition to financial payments, the blockchain industry will enter the field of securities, loans and other derivative financial products. Companies such as Securitize*, Dharma, Dydx, Compound Finance and The Ocean are all committed to creating decentralized finance. companies.
Over the past few years, mobile app companies such as RAP, Gojek and Paytm have branched out, emerging with products such as payments, investments, remittances, loans and insurance. As many Asian economies shift away from cash digital economy, they are rapidly attracting users of neobanks.
Asian regulators are providing clearer guidelines for blockchain and digital currency projects, as they see blockchain as a catalyst for economic growth, with It may become a sunrise industry in the future.
In addition, more than 80% of digital currency transaction volume comes from Asia, so digital currency investors are very eager to establish reliable infrastructure. If Grab, Gojek and Paytm can benefit from digital currency investors If they benefit from it, then they will start to support the blockchain more strongly and provide a better experience for payments, loans and other derivative financial products.
Back to the original intention
In the past few years, digital currency The industry has strayed from its original financial vision, and this is well laid out in Satoshi Nakamoto’s Bitcoin white paper. Just like the boom and bust of the internet, so does almost every real-world example imaginable, like tracking the freshness of flowers. logistics chains are using the hot word blockchain to attract attention.
However, just like the early Internet, real implementation cases must match the development stage of the technology.
For example, Netflix does not It may have been possible to successfully stream TV shows in 2000, when less than 1% of the population had access to broadband. Over the past few years, it has become increasingly clear that payments are a real-world example of where blockchain is now being used at scale.< br/>In 2019, blockchain companies will build on this foundation and use smart contract platforms to rapidly develop in decentralized financial applications (such as loans and insurance products).
I always find that the best applications happen in specific market segments. As long as blockchain companies can focus on products that solve specific problems, then we will see more competitive products. , innovative blockchain companies.
And, this is a good thing for the entire industry.

F. What can blockchain be?

Blockchain is a term in the field of information technology. In essence, it is a shared database in which The data or information has the characteristics of "unforgeable", "leaving traces throughout the entire process", "traceable", "open and transparent" and "collectively maintained".
As an important concept of Bitcoin, blockchain is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains Collects a batch of Bitcoin network transaction information to verify the validity of the information (anti-counterfeiting) and generate the next block.
On January 10, 2019, the Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations". On December 2, 2019, the word was selected into the top ten buzzwords of 2019 by "Yi Wen Qi Zi".
