Ⅰ Is Bitcoin an application of blockchain?

Bitcoin is a practical application of blockchain

The financial crisis broke out in 2008. A pseudonym named "Satoshi Nakamoto" published a paper based on blockchain technology to improve the story of Lao Wangcun:

1) Because Bitcoin circulates globally, the "element" in the story "Change it to btc, 100 yuan = 100btc

2) The anonymity of Bitcoin. The way everyone in the story keeps accounts will announce to the world how much money you have in your pocket. Presumably everyone does not Everyone in the Bitcoin network has a wallet address, which is a code composed of several binary digits.

3) Improvement of transaction mechanism, optimization and improvement of accounting, etc.

So what are the current application scenarios of Bitcoin?

1) For investment

The current total market value of Bitcoin is 967.236 billion, accounting for 50% of the current total market value of cryptocurrency. If you are a Chinese between 20 and 50 years old and have a stable job, then you have learned about the news that Bitcoin has risen from 3,000 to 8,000 in half a month on a hot search on the Internet. At this time, you just happened to see this post of mine. article, then you will definitely think of one thing: should you invest in this thing? And is the risk high?

Personally, I think Bitcoin is more suitable for fixed investment (invest part of your salary in Bitcoin every month, if you get a salary of 4,000, you can invest 300 at a fixed time point every month) , In the cryptocurrency trading market, some people have become rich because of Bitcoin, and some have sold their houses because of Bitcoin speculation. The total market value of the cryptocurrency trading market is not large, and there are indeed some experts, large and small, who are pulling the strings. Changes It is unpredictable, but looking at the development in the past 10 years, cryptocurrency has shown a state of healthy development and has been recognized by more and more countries.

Ⅱ What are the differences and connections between blockchain and Bitcoin?

Blockchain technology is a new technology derived with the development of the Bitcoin economy. Blockchain technology can effectively The ground serves the Bitcoin economy, and they are interconnected. Bitcoin is a virtual currency that only circulates in a specific network economic environment. Blockchain technology can not only be applied to the economy, but can also be used in all walks of life. This is their difference.

Blockchain Technology

Because blockchain technology is still an emerging product, it does not yet have an accurate or definite definition and concept. Simply put, blockchain technology is a model for encrypted management of data, which can protect data to a large extent. Blockchain technology has the distinctive characteristics of decentralization, openness, independence, security and anonymity. Its characteristics are well adapted to today's requirements for information protection and information disclosure in all walks of life. On the one hand, it ensures data security and avoids data processingIt is interfered by factors such as human subjective emotions and system failures. On the other hand, it is up to the individual data to decide whether to hide their details from the group to the greatest extent possible to achieve the purpose of protecting privacy.

At the same time, there is no doubt that blockchain technology is still in a preliminary state of development. Society's understanding of it is not deep enough, and scholars are still in the stage of continuous exploration. Through correct application, blockchain technology will bring many positive impacts to society.

Ⅲ What is blockchain and what is its connection with Bitcoin

Blockchain was born from Satoshi Nakamoto’s Bitcoin and was first proposed by Satoshi Nakamoto in 2008. Blockchain concept.
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-tamperable. Unforgeable distributed ledger.
Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure the security of data transmission and access. A new distributed infrastructure and computing method that utilizes smart contracts composed of automated script code to program and manipulate data
Blockchain format as a solution to make databases secure without requiring credit from administrative agencies First applied to Bitcoin. In October 2008, in Satoshi Nakamoto's original paper, the words "block" and "chain" were used separately, but when they were widely used, they were collectively called block-chain. By 2016 It was turned into a word: "blockchain". In August 2014, Bitcoin’s blockchain file size reached 20 gigabytes.

IV What are the main application areas of blockchain technology

Blockchain is the core supporting technology of the digital cryptocurrency system represented by Bitcoin. The core advantage of blockchain technology is decentralization. By using data encryption, timestamps, distributed consensus and economic incentives, it can realize decentralized trust-based trust bridges in a distributed system where nodes do not need to trust each other. Point-to-point transactions, coordination and collaboration provide a solution to solve the common problems of high cost, low efficiency and insecure data storage in centralized institutions.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. Blockchain and Bitcoin are booming, and many related top domain names are was registered and had a relatively large impact on the domain name industry.

IV How to explain in an easy-to-understand manner what blockchain is and what Bitcoin is?

Let’s talk about the social or economic significance of blockchain. Many technologies in the past were actually dedicated to "productivity", such as artificial intelligence, which is an advancement in productivity. The blockchain has greatly improved production relations and is dedicated to production relations. So why do you say that?
BecauseThe so-called production relations are actually how business is done between people and business partners. And these things are originally in the process of people's mutual cognition, and no special procedures are used to program or quantify them.
For example, if you and I are good friends now, we can do business. If someone provokes our relationship and we are no longer good friends, we will not do business. Even if we can make money by doing business, we will not do it. , because everyone no longer has any trust in each other.
As for the blockchain, it is actually because the data has been certified by various nodes and backed up at the same time, so my data is as authentic as possible and cannot be tampered with. So in this case, you believe my data, On this basis, you can create a program, and then program the "production relations" of what kind of business contracts and business cooperation this data can be used for. In this way, everyone believes in the data and the program compiled by the algorithm. And because you believe in the data and the program, you can develop various APPs based on this program. These APPs are the relationship of production and what kind of business you are going to do. This is: Blockchain is actually a reconstruction of "production relations".

VI What are the application fields of blockchain?

What are the application fields of blockchain? Introduction to the Blockchain Application Industry
As we all know, blockchain is very popular now. It is a shared distributed database technology. Blockchain technology will have very good results in different industries with its remarkable characteristics. Development prospects, so what are the application areas of blockchain?
Blockchain Applications
1. Digital Currency: At present, the most extensive and successful application of blockchain technology is the digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency. Since the emergence of Bitcoin, hundreds of digital currencies have appeared one after another, and a relatively large industrial chain ecosystem has been formed around the generation, storage, and transactions of digital currencies. Taking Bitcoin as an example, participating institutions can be mainly divided into four categories: infrastructure, trading platforms, ICO financing services, and comprehensive blockchain services.
2. Financial application: Blockchain has inherent advantages in the financial field. On the Internet, this is determined by the genes of blockchain. From a subjective point of view, financial institutions are the most willing to explore blockchain applications and need new technologies to improve operational efficiency and reduce costs to cope with the current status of the entire global economy. Objectively speaking, the market space in the financial industry is huge, and a little progress can bring huge benefits. The financial industry is an industry with extremely high requirements for security and stability. If the application of blockchain in the financial field is verified, it will have a huge demonstration effect and be quickly promoted in other industries. In the financial field, in addition to digital currency applications, blockchain is also gradually used in cross-border payments, supply chain finance, and insurance.Applications have begun in insurance, digital bills, asset securitization, bank credit reporting and other fields.
(1) Insurance business: With the development of blockchain technology, personal health status, accident records and other information may be uploaded to the blockchain in the future, allowing insurance companies to be more timely and timely when customers apply for insurance. Accurately obtain risk information to reduce underwriting costs and improve efficiency. The shared and transparent characteristics of the blockchain reduce information asymmetry and the risk of adverse selection; while its historical traceability characteristics are conducive to reducing moral hazard, thereby reducing the difficulty and cost of insurance management.
(2) Asset securitization: The business pain point in this field lies in the fact that the authenticity of the underlying assets cannot be guaranteed; there are many participating entities, multiple operating links, low transaction transparency, and information asymmetry, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue.
(3) Digital tickets: The pain points in this field lie in three risk issues. Operational risk: Due to the centralization of the system, once there is a problem with the central server, the entire market will be paralyzed; market risk, according to statistics, in 2016, there were seven risk events involving hundreds of millions of dollars, involving multiple banks; moral hazard , there are incidents such as "one ticket selling more" and false commercial bills in the market. Blockchain's disintermediation, system stability, consensus mechanism, and non-tampering characteristics reduce operational risks, market risks, and moral risks in traditional centralized systems.
(4) Cross-border payment: The pain points in this field are long payment cycle, high fees and low transaction transparency. The third-party payment company is the center to complete the accounting, settlement and liquidation in the payment process, and the payment cycle is long. For example, the payment cycle for cross-border payments is more than three days, and the cost is high. The blockchain is deintermediated, transactions are open, transparent and cannot be tampered with. No third-party payment institutions are involved, which shortens the payment cycle, reduces fees and increases transaction transparency.
(5) Credit information management: The pain points in this field are the lack of data sharing, information asymmetry between credit information agencies and users; formal market-oriented data collection channels are limited, and the battle for data sources consumes a lot of costs; data privacy protection issues are prominent , the traditional technical architecture is difficult to meet new requirements, etc. In the field of credit reporting, blockchain has the characteristics of decentralization, trustlessness, timestamps, asymmetric encryption and smart contracts. At the technical level, it ensures that limited and controllable credit can be achieved on the basis of effectively protecting data privacy. Data sharing and verification.
(6) Supply chain finance: The pain points in this field are the long financing cycle and high costs. Centered on the core enterprise system of the supply chain, it is difficult for third-party credit enhancement institutions to authenticate the authenticity of various relevant vouchers in the supply chain, resulting in long manual review times and high financing costs. Blockchain disintermediation, consensus machineIt is unique and cannot be tampered with. It does not require a third-party credit enhancement agency to verify the authenticity of various relevant vouchers in the supply chain, reducing financing costs and shortening the financing cycle.
(7) Asset securitization: The business pain point in this field lies in the fact that the authenticity of the underlying assets cannot be guaranteed; there are many participating entities, multiple operating links, low transaction transparency, and information asymmetry, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue. Blockchain's deintermediation, consensus mechanism, and non-tampering characteristics increase data flow efficiency, reduce costs, monitor the true status of assets in real time, and ensure the trust of all parties in the transaction chain in the underlying assets.
3. Blockchain + Industry Application:
As the application of blockchain technology in the financial field continues to be verified, its technical advantages are gradually showing value in other industries. At present, blockchain application projects are gradually being implemented in fields such as medical and health, IP copyright, education, culture and entertainment, communications, charity, social management, sharing economy, and the Internet of Things, and "blockchain+" is becoming a reality.
(1) Blockchain + Medical: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to protect patient privacy. Electronic health records (EHR), DNA wallets, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of medical institutions around the world will invest in blockchain technology by 2020.
(2) Blockchain + Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, supply chain management, sharing economy, etc. are included, the Internet of Things application of blockchain technology will become a very important application field.
(3) Blockchain + IP copyright & cultural entertainment: The Internet is developing better and better, and digital music, digital books, digital videos, digital games, etc. have gradually become mainstream. The rise of the knowledge economy has made intellectual property rights a core element of market competition. However, intellectual property infringement is serious in the current Internet ecosystem, and the copyright protection of digital assets has become a pain point in the industry. Blockchain has the characteristics of disintermediation, consensus mechanism, and non-tampering. Blockchain technology can effectively integrate all aspects of the cultural and entertainment value chain, accelerate circulation, and shorten the value creation cycle; at the same time, the value of digital content can be realized Transfer, and ensure that the transfer process is credible, auditable and transparent, effectively preventing piracy and other behaviors.
(4) Blockchain + Public Services & Education: In the fields of public services, education, charity and public welfare, issues such as file management, identity (qualification) certification, and public trust all exist objectively. The traditional method is to rely on A credible third party provides credit endorsement, but problems such as fraud and deficiencies still exist. Blockchain technologyThis technology can ensure the integrity, permanence and unchangeability of all data, and thus can effectively solve the difficulties and pain points in these industries in aspects such as certificate storage, tracking, correlation, and backtracking.

VII What is the relationship between Bitcoin and blockchain?

The emergence of Bitcoin has brought a new technology, blockchain, into the public eye. What is the relationship between Bitcoin and blockchain? The simplest understanding is that blockchain is the underlying technology of Bitcoin, and Bitcoin is the first generation application of blockchain, so we often see a saying that "Bitcoin represents the blockchain 1.0 era" ".

Bitcoin is regarded as the first generation application of blockchain technology, and it is also the application with the most thorough code testing. However, without Bitcoin, not so many people may know about blockchain now. It can be said that Bitcoin has greatly increased the “exposure” of blockchain technology.

Afterwards, people gradually discovered that the application value of blockchain is far beyond Bitcoin, but can be applied to many industries and solve the pain points of many industries; and the idea of ​​blockchain can also Providing many references for the financial field is the reason why blockchain really explodes.

Ⅷ What is blockchain and what areas can it be used in?

I have seen your question. So, where can blockchain be used? The editor will answer it for you below.

Answer: Bitcoin is the first specific application of blockchain. It was proposed in a paper in 2008 by a person or group of people. Bitcoin uses the blockchain to digitally send bitcoins, as BitCoin is known, without the intervention of a third-party middleman.

But Bitcoin is not the only application of blockchain, as follows:

1. Financial field: Applying blockchain technology to the financial industry can eliminate the need for third-party intermediaries links to achieve direct point-to-point docking, thereby quickly completing transaction payments while greatly reducing costs.

2. Internet of Things and logistics fields: Blockchain can also be naturally combined in the fields of Internet of Things and logistics. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved.

3. Public service field: Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields. However, the centralized nature of these fields also brings some problems. It can be used to distinguish Blockchain to transform.

4. Digital copyright field: Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership

< p>5. Insurance field: In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the policy will be realized.Automatic claims settlement.

6. Public welfare field: The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

The above is for your reference only, I hope you can adopt it, thank you!

Ⅸ What is the relationship between blockchain and Bitcoin?

Blockchain technology is the basic technology of Bitcoin and is also the core and infrastructure of Bitcoin. Bitcoin has always been operated and managed without any centralized organization. Later, Bitcoin technology was abstracted and called blockchain technology, or distributed ledger technology.

(1) Blockchain is the core and infrastructure of Bitcoin:

1. In the Bitcoin system , "currency" is simply the unit of account used in that ledger. The most important thing is not the concept of "currency", but the concept of "ledger" without a central storage organization. For example: I lend 50 yuan to someone else. At this time, I asked the financial staff to help me keep accounts.

2. Blockchain technology is the basic technology of Bitcoin and the core and infrastructure of Bitcoin. Bitcoin has always been operated and managed without any centralized organization. Later, Bitcoin technology was abstracted and called blockchain technology, or distributed ledger technology.

(2) Blockchain is the core and infrastructure of Bitcoin:

1. In the Bitcoin system, “currency” is just the accounting used in the ledger. unit. The most important thing is not the concept of "currency", but the concept of "ledger" without a central storage organization. For example: I lend 50 yuan to someone else. At this time, I asked the financial staff to help me keep accounts. Bookkeeping must be paid, so I need to pay the financial staff.

Because an incentive mechanism has also been invented in the Bitcoin system technology, which is equivalent to what I just said, you can help me keep accounts and I will pay you, but not everyone has accounting rewards. Therefore, the blockchain has designed a corresponding mechanism competition mechanism.

2. The competition mechanism uses a hash algorithm to determine the ownership of rewards. Generally speaking, everyone is given a math problem. The reward is for whoever calculates the result first. The calculation process of the hash algorithm is a process in which a professional computer (we call it a miner) uses the hash algorithm to calculate the results, which is called mining.

For the fastest and best bookkeepers, the system writes the recorded contents into the account books and sends the account book contents to everyone in the system for backup. This way, everyone in the system has a complete ledger called blockchain technology.

(3) The origin of blockchain:

1. The origin of the word "blockchain" is from the original English version of the Bitcoin white paper "Blockchain". When translating this sentence, the Chinese market directly used the word "blockchain" and then directly wrote it as "blockchain", which became the globalA proper noun for global blockchain technology.

So, no matter who explains the blockchain, Bitcoin cannot be bypassed. If you want to introduce the history of cars, just like you can't avoid Carl Benz; if you want to introduce the history of airplanes, just like the Wright brothers.

2. Bitcoin "invented" and proved the feasibility of blockchain technology. Bitcoin is not the entire blockchain technology, just one of its applications. But without Bitcoin, or if Bitcoin's applications were not successful, blockchain might not have emerged, or at least not for many years. Therefore, it is difficult for the blockchain to be "isolated" from Bitcoin for a long time.

(9) Extended reading on the application of Bitcoin and blockchain technology:

Blockchain applied to digital currency Disadvantages of technology:

First, "decentralization" does not have a circulation management agency. In essence, blockchain technology is a distributed database system, its logical structure is a one-way linked list, and its design model is based on P2P network, which determines that there is currently no unified virtual currency central control system based on blockchain technology. .

Second, quantity supply is difficult to effectively control. Based on blockchain technology, the issuance amount of virtual currency is fixed. According to the Fisher equation, at a certain price level, the total transaction volume of the whole society in a certain period has a certain ratio to the required nominal amount of money, and a fixed amount of money obviously cannot meet the requirements of the ever-increasing total price of social commodities.

Third, it is difficult for the “mining mechanism” to create recognized value. Bitcoin itself has no value and is not backed by national credit. Some people think that "value is injected into virtual currency by continuously consuming computing power and energy", but in order to find a hash value that meets the requirements, spending millions of calculations is obviously not the most efficient option.

Fourth, producers and early holders can easily obtain high seigniorage taxes. Any virtual currency based on blockchain technology will be held by a small number of people in the early stages of development. Take Bitcoin for example. At first, Bitcoin was just a product of a few people's game. In May 2010, the first transaction to buy Bitcoin was a $25 pizza purchased for 10,000 Bitcoins, and the first transaction completed in July of the same year was $0.04/Bitcoin.

Ⅹ Comprehensively interpret blockchain and Bitcoin, teach you to understand the relationship between the two, and be prepared for any danger

When talking about blockchain, the word "Bitcoin" is often inseparable. Because today's cryptocurrencies are all issued in the name of blockchain, some people easily confuse the two concepts. Next, Kelian Cloud Technology will comprehensively explain the difference between blockchain and Bitcoin and teach you to understand the relationship between the two.

Blockchain is a distributed account. Simply put, it is a decentralized ledger that can be viewed and joined by many people. For example, each block is equivalent to each knot on a rope. When each new transaction enters the blockchain, it means that something has happened. To mark the occurrence of something, a symbol will be used. tie a knot and tie it on a specific knotRecord detailed information below.

Bitcoin uses blockchain to realize value storage and transactions. In addition, the technical difficulty of the blockchain itself is not the most difficult. The most difficult thing is its application scenarios and the regulatory issues it will face. .

There are three classifications of blockchain, namely public blockchain, private blockchain, and joint blockchain; the other classification is without authority and permission.

Therefore, cryptocurrencies use blockchain technology, but blockchain technology is not exclusive to cryptocurrencies

When the financial crisis came, some investors chose to invest in cryptocurrencies. In order to avoid corresponding asset risks, thanks to the mechanism of blockchain to solve trust problems, this technology has been applied in financial management and transactions. The main manifestation is that blockchain can track various types of transactions and can also play a role in anti-counterfeiting and traceability in various scenarios. Issues such as copyright, trademark, and academic fraud have been exposed.

In addition, blockchain technology can also simplify transactions, make the entire transaction process open and transparent, and track every link of the transaction event to ensure that both parties have a certain degree of trust.

When "mining", the open source blockchain network can ensure trust and has the characteristics of being non-tamperable. When the networked computers undergo sophisticated algorithms, the correct answer comes out, and "absentees" You will get mining rewards and can use servers all over the world, but the whole process is still very energy-consuming.

It may be this misunderstanding that causes the public to confuse the concepts of Bitcoin and blockchain. Although more than 90% of current blockchain projects have issued coins, there are very few projects that can actually be implemented. In addition, the crazy mining practice of Bitcoin wastes graphics cards and electricity to a large extent.

Bitcoin is an open source version of blockchain technology, that is, a network developed for everyone. It is popular for its decentralization advantages. However, as a public blockchain, Bitcoin However, mining consumes a lot of computing power, resulting in serious power consumption in many countries.

Therefore, for an emerging technology, it is best not to blindly trust or invest in it. Only by recognizing its true purpose can you see everything objectively and be prepared.
