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 does blockchain mean?

Blockchain, an important concept of Bitcoin, is essentially a decentralized database that simultaneously Zhibu is 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. (anti-counterfeiting) and generate the next block.

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

2. In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China’s economy, accelerate the circulation of global assets, and realize the renaissance that generations have been striving for. dream.

Puyin Group held the Puyin Blockchain Finance Guiyang Strategy Release Ceremony in Guizhou on December 9, 2016. At the meeting, the blockchain will realize the digital circulation of assets and the blockchain financial transaction model. , and discuss the application of blockchain services and social public industries.

C. What does blockchain mean?

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

1. 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-forgeable. Distributed ledger.

2. Blockchain is an important concept of Bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of Bitcoin, it is a series of related cryptographic methods. data block.

(3) What is the blockchain? 6 Extended reading:

1. The Bitcoin peer-to-peer network stores all transaction history in In "blockchain". The blockchain continues to lengthen, and once new blocks are added to the blockchain, they cannot be removed.

2. The blockchain shared value system was first imitated by many cryptocurrencies, and improvements were made in proof of work and algorithms, such as the use of proof of equity and SCrypt algorithms.

3. The blockchain is actually a group of dispersed user nodes and a distributed database composed of all participants. It is a record of all Bitcoin transaction history.

4. Blockchain technology will be applied to credit reporting, transaction security and information security in the financial industry. Blockchain can form point-to-point digital value transfer in finance, thus improving the security of transmission and transactions.

D. 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.

The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which 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 andUnforgeable 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.

E. What is blockchain

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

The essence of the blockchain is a distributed public ledger. Anyone can verify this ledger, but no single user can control it. Participants in a blockchain system jointly maintain a ledger: it can only be modified according to strict rules and consensus.

The development of blockchain has gone through three stages:

1. Incubation period: 2009-2012, the economic form was dominated by Bitcoin and its industrial ecology.

2. Embryonic period: The period is from 2012 to 2015. Blockchain entered the public eye with Bitcoin, new wallet payment and remittance companies appeared, and the blockchain economy spread to the financial field. The underlying technology of blockchain continues to innovate. Blockchain technology is divorced from the Bitcoin system.

3. Development period: In 2016, industry applications began to be explored, and a large number of blockchain startups emerged. The popularity of ICO in 2017 brought unprecedented attention to blockchain.

(5) What is the blockchain for 6 Extended reading:

Three characteristics of the three blockchains:

1. The core idea of ​​the blockchain is decentralization: in the blockchain system, the rights and obligations between any nodes are equal, and all nodes have the ability to vote with computing power, thus ensuring the The recognized result is the result recognized by more than half of the nodes. Even if it suffers a severe hacker attack, as long as the number of nodes controlled by the hacker does not exceed half of the total number of global nodes, the system will still be able to operate normally and the data will not be tampered with.

2. The biggest disruption of blockchain lies in the establishment of credit: in theory, blockchain technology can make WeChat Pay and Alipay no longer valuable. The Economist made a vivid metaphor for blockchain: simply put, it is “a machine that creates trust.” Blockchain allows people to collaborate without trusting each other and without a neutral central authority. Combating counterfeit currency and financial fraud will no longer be needed in the future.

3. The collective maintenance of blockchain can reduce costs: In a centralized network system, the maintenance and operation of the system rely on the operation, maintenance and operation of platforms such as data centers., the cost cannot be omitted. Anyone can participate in the nodes of the blockchain. While participating in the recording, each node also verifies the correctness of the recording results of other nodes, which improves maintenance efficiency and reduces costs.

In one sentence, blockchain touches money, trust and power, which are the fundamental foundations on which human beings rely for survival.

F. What does blockchain do

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

Blockchain is also a decentralized distributed ledger system that can be used to register and issue digital assets, property rights certificates, points, etc., and conduct transfers, payments and transactions in a point-to-point manner. Compared with traditional centralized ledger systems, the blockchain system has the advantages of being completely open, non-tamperable, preventing multiple payments, and does not rely on any trusted third party.

In other words, the previous computing model required a computer to perform all calculations to draw conclusions, while the technical application of blockchain is to use "distribution" to transfer a complex operation separately. Giving N multiple computers to perform simultaneous operations not only reduces the storage load of each computer, but also saves time. Finally, all results are integrated through the "consensus mechanism" to obtain the final result.
