㈠ What is blockchain and what is its relationship with Bitcoin
Blockchain in English is Blockchain, which is a computer for distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. New application models of technology. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system. Blockchain is the underlying technology of Bitcoin, which is like a database ledger that records all transaction records. This technology has gradually attracted the attention of the banking and financial industries because of its safety and convenience. It is a very important concept in the blockchain world. Many models, such as ledger maintenance, currency issuance, timestamp design, network maintenance, competition between nodes, etc., all rely on this central idea.
The first application of blockchain was Bitcoin, and many countries have recognized the legal status of Bitcoin. There is no Bitcoin organization or central bank in the world to issue Bitcoin. The credibility it relies on is the algorithm. It relies on testing the algorithm and an account book and fair mechanism to ensure circulation. It develops a currency that everyone recognizes and trusts. A mechanism, that's how it works.
Nowadays, people’s concept of blockchain is still very general, and its applications are not very wide. However, in the next ten years or even decades, when it comes to blockchain, it will definitely be the most high-end technology that affects people of all ages. Everyone knows!
㈡ What is the relationship between blockchain technology and Bitcoin?
Blockchain technology is the underlying technology 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.
Bitcoin is the first application of blockchain and will be expanded to more and more industries in the future.
Blockchain technology is called distributed ledger technology. It is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to participate in database records.
While Bitcoin is not issued by a specific monetary institution, the Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all transaction behaviors, and uses cryptographic design to ensure A currency that provides security in all aspects of currency circulation.
(2) Extended reading of blockchain protocol and Bitcoin protocol:
Bitcoin currency characteristics:
Decentralization : Bitcoin is the first distributed virtual currency. The entire network is composed of users and there is no central bank. Decentralization is the guarantee of Bitcoin’s security and freedom.
Worldwide circulation: Bitcoin can be managed on any computer connected to the Internet. Anyone can mine, buy, sell or receive Bitcoin regardless of location.
Exclusive ownership: Manipulating Bitcoin requires a private key, which can be isolated and stored on any storage medium. No one can obtain it except the user himself.
Low transaction fees: It is free to send Bitcoin, but there will ultimately be a transaction fee of approximately 1 bit cent per transaction to ensure faster transaction execution.
No hidden costs: As a means of payment from A to B, Bitcoin has no cumbersome limits and procedures. You can make the payment by knowing the other party's Bitcoin address.
Cross-platform mining: Users can explore the computing capabilities of different hardware on many platforms.

㈢ What are the differences and connections between blockchain and Bitcoin
Blockchain technology is As new technologies derived from the development of the Bitcoin economy, blockchain technology can effectively serve 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 TechnologyBecause 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 prevents data processing from being 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.
㈣ What is the relationship between blockchain and Bitcoin?
What is the relationship between blockchain and Bitcoin?
Q1:
So what is the relationship between blockchain and Bitcoin?
Before answering this question, we must first clarify what Bitcoin is.
Bitcoin is a brand new digital currency, but this so-called "currency" has a characteristic, that is, it has no issuing agency.
Q2:
Then you may ask, how does Bitcoin ensure the security and stability of the entire system without the management of an issuing agency?What about qualitative?
A special technology is needed here, and this special technology is "blockchain" technology. So we say that blockchain is the underlying technology of Bitcoin.
However, blockchain technology is not a brand-new thing. It is a technology that combines classic disciplines such as cryptography, distributed storage, consensus mechanisms, and smart contracts. As Bitcoin became known, the technology used in the Bitcoin system was vividly called "blockchain".
So we say that Bitcoin is the first application of blockchain, and Bitcoin represents the blockchain 1.0 era. The distinctive feature (or application scenario) of the blockchain 1.0 era is the digital currency represented by Bitcoin.
The birth of Bitcoin, or the emergence of blockchain technology, has a certain background.
In 2008, the world was in the midst of a severe economic crisis. The Federal Reserve's issuance of additional currency aggravated inflation and the economic crisis further spread. As a result, a person with the pseudonym "Satoshi Nakamoto" began to explore a new currency model, that is, the issuance of currency no longer relies on centralized institutions, so as to avoid the consequences of mistakes in decision-making by centralized institutions. All kinds of crises.
In 2008, Satoshi Nakamoto described the technical principles of Bitcoin in detail in a paper "Bitcoin: A Peer-to-Peer Electronic Cash System".
From this paper we can summarize that one of the biggest features of the Bitcoin system is "decentralization". In other words, the power to maintain the Bitcoin system is no longer concentrated on a central server, but relies on every node on the system. Through cryptography and other computing methods, it is ensured that Bitcoin, the "digital currency", can not be duplicated. At the same time, the circulation and transactions of Bitcoin can be well recorded.
Q3:
So, how to better record Bitcoin circulation transactions without the management of a central organization?
This involves the term "distributed storage". What does distributed storage mean? We can make an analogy and think of the Bitcoin system as a "ledger", which records Bitcoin transactions. However, this "ledger" is not concentrated in the hands of one person, but is decentralized. In other words, every node on the Bitcoin system has such an ledger, and everyone keeps accounts together. If you want to update the accounts, you need the consent of the majority of people... The "distributed storage" method of recording data used by the Bitcoin system has become one of the core technologies of the blockchain.
In addition, on the Bitcoin system, nodes must follow certain rules when recording data. This rule is called the "consensus mechanism". Bitcoin's consensus mechanism is PoW, which is proof of work. The mechanism, to put it simply, means more work, more reward. Nodes do a lot of calculations through computersBy recording transactions on the Bitcoin system and maintaining the Bitcoin system, you can get more Bitcoin rewards... The "consensus mechanism" adopted by Bitcoin has also become one of the cores of blockchain technology.
Later, with the continuous enrichment of blockchain technology, consensus mechanisms also became diverse. Simply put, the consensus mechanism can be understood as the incentive mechanism of blockchain technology, because blockchain is decentralized and requires certain incentives to encourage nodes to proactively maintain the system.
From the above description, we can conclude that the Bitcoin system uses cryptography, distributed storage, consensus mechanism and other technical means to ensure that the system can be safe and stable without a central organization. run. These technologies are vividly summarized as "blockchain technology".
Therefore, we can understand the relationship between blockchain and Bitcoin like this:
Blockchain technology is the underlying technology of Bitcoin,
Bitcoin Bitcoin is the first application of blockchain;
Bitcoin represents the blockchain 1.0 era. The distinctive feature of this era is that blockchain technology is applied to the exploration of digital currency.
Whether it is Bitcoin or blockchain, if you say they are technologies, that is completely OK, because they are essentially the underlying protocol of a computer. This protocol is essentially the same as the Internet protocol we use now. It is completely different if you say it is an idea. Blockchain contains democratic ideas and incentive mechanisms. These ideas have great reference significance for our current community governance.
Of course, gold is never pure. After Bitcoin, blockchain was accepted by more people. At this time, a large number of altcoins emerged. These altcoins evolved into a new financing model, resulting in air coins, MLM coins, etc. The prevalence of currency flag fraud. Regarding this point, with the current tightening of supervision and improvement of legislation, those who defraud using blockchain technology will also be severely punished.

㈤ What is the essence of blockchain and what is the principle of Bitcoin? What is the difference between the two?
The price of one Bitcoin has skyrocketed from more than 20,000 US dollars to 40,000 US dollars. This can't help but arouse my research interest, or to briefly understand what Bitcoin is, what its mechanism is like, and to uncover its mystery. Therefore, I simply searched for some information and learned a little bit about Bitcoin, so I sorted out the information on hand.
(3) Purpose: decentralization, reducing risks
Centralized network Only the central server can store and process data. Its disadvantage is that the workload is large. Once it is paralyzed, the entire system will be paralyzed; the amount of data storage is large; the central manager has the right toLarge limit.
All servers in the distributed network can store and process data. Each server has an equal status and can store more data and have higher security.
The general popular science content is like this. If you want to know more, you can take a look at Satoshi Nakamoto’s paper and the official popular science video below.
㈥ Comprehensive interpretation of blockchain and Bitcoin, teach you to understand the relationship between the two
01 Blockchain is the underlying technology of Bitcoin
A blockchain is a distributed account, in short, a decentralized ledger that can be viewed and joined by many people. For example, each block is equivalent to each knot on the rope. When each new transaction enters the blockchain, it is equivalent to an event. To mark the occurrence of an event, a symbolic knot is made and the details are recorded on the specific knot
Bitcoin uses blockchain for value storage and transactions. In addition, the technical difficulty of the blockchain itself is not the greatest, but its application scenarios and regulatory issues include three types of blockchain: public blockchain, private blockchain and joint blockchain; the other classification is permissionless and permissions
Therefore, cryptocurrency uses blockchain technology, but blockchain technology does not entirely belong to cryptocurrency
02 When the financial crisis comes, blockchain technology It can prevent counterfeiting, trace the source, and simplify transactions in the financial industry. Some investors choose to invest in cryptocurrency to avoid corresponding asset risks and benefit from the mechanism of blockchain to solve trust problems. This technology has been applied to financial management and transactions. The main performance is that blockchain can track various types of transactions and can also play an anti-counterfeiting and traceability role in various scenarios. Copyright, trademark, academic fraud and other issues have been exposed one after another
In addition, blockchain technology can also simplify transactions, make the entire transaction process open and transparent, track the links of each transaction event, and ensure that both parties have certain rights. Degree of trust
03 The concept of Bitcoin is different from that of blockchain
During the "mining" process, the open source blockchain network can ensure trust and cannot be tampered with. When networked computers run through a precise algorithm and give the correct answer, the "absentees" will be rewarded for mining and have access to servers around the world, but the whole process is still very energy-consuming
Currency Chart B Coin: A comprehensive explanation of blockchain and Bitcoin will teach you to understand the relationship between them. Bitcoin is an open source version of blockchain technology, that is, a network developed for everyone, and it is popular for its decentralized advantages. However, as a public blockchain, Bitcoin consumes a lot of computing power due to mining, which leads to severe power consumption in many countries
Therefore, for an emerging technology, it is best not to be blind trust or investment and recognize its true purpose in order to see an objectivelyCut and prepare.

㈦ What is the difference between blockchain and Bitcoin?
area Blockchain is technology and Bitcoin is virtual currency.
Blockchain technology is a decentralized consensus mechanism that maintains a complete, distributed, and non-tamperable ledger database. It allows participants in the blockchain to implement a unified ledger system without establishing a trust relationship.
In the future, blockchain will be applied in any field and will have a great impact on human life. Blockchain technology is regarded as one of the main protocols for the next generation of value Internet. Blockchain technology will be useful in any area of production and life that lacks trust. It can be widely used in fields ranging from digital currency to securities and financial contracts, medical treatment, games, artificial intelligence, smart contracts, Internet of Things, identity verification, asset trading, e-commerce, social communication, file storage and other fields.
Medical aspects
Using blockchain technology to save personal medical records will have personal medical historical data, which can be understood as electronic medical records on the blockchain. Data will be available for future medical treatment or health planning, and the real owner of this data is the patient himself, not the hospital or a third-party organization. In addition, these data have strong privacy, and the use of blockchain technology can also help protect patient privacy.
Payment System
Compared with the existing traditional payment system, blockchain technology can avoid complicated systems and conduct transactions directly between the two parties without involving intermediaries. Even if part of the network is paralyzed, it will not Will affect the operation of the entire system. This method is low-cost, fast, and requires no intermediate handling fees.
Banking
As a digital, secure and tamper-proof account, blockchain realizes the core function of the banking industry: a secure storage and transfer center for value. Some banks with a keen sense of smell in the world have begun to actively plan and join the blockchain research and application army, hoping to gain the initiative in the fierce competition in the future.
Blockchain Identity Authentication
Blockchain has the feature that everyone can check it. Everyone can query block information anywhere there is a network. The highly transparent feature also makes the block The chain is full of charm. In the future, ID cards and household registration books will be basically unnecessary, because every identity information can be written into the blockchain. When you need to verify information, you only need to look it up to find it.
Election
Based on voting transactions on the blockchain, it can be confirmed that no votes have been modified or deleted, and there will be no improper votes.
Real Estate
Blockchain technology can change the way the real estate market operates. It can merge many complex processes and cases that real estate companies usually deal with, speed up transaction processes, reduce fraud, and provide benefits for every participant. Provide more transparent and secure transactions. Provides a way to achieve paperless and fastdemand for speedy transactions.
Securities issuance and trading
General stock and other securities transactions have a high probability of various errors, requiring manual error correction, which prolongs the time required for transaction settlement. Transactions through distributed ledgers can automate the entire process and improve security and efficiency. The identity of the transaction party, transaction volume and other information are recorded on the blockchain in real time, coupled with an open, transparent and traceable system. It is conducive to market maintenance by securities issuers and regulatory authorities, and can reduce the occurrence of black-box operations, insider trading, etc.
Blockchain has unique technical advantages, shows unique charm, and has great application imagination in scenarios where it is relatively closed, has multi-party trust issues, and carries value transfer. At the current stage, blockchain is worth exploring in some scenarios.
㈧ Do you know the essence of blockchain and what is the principle of Bitcoin?
Blockchain has been developed to this day for some time. During this time, people The understanding of blockchain has experienced rapid changes.
The essence of blockchain is technology
Since we talk about the essence, what is the essence? The essence should be traced back continuously until it can no longer be traced back. Only then can what is obtained be called the essence. The essence of blockchain is a technology. Going back to the original starting point of the blockchain, when Bitcoin was first born, the problem it had to solve was the Byzantine Generals Problem. From a professional perspective, it was to solve the problem of how to achieve consistency in a distributed environment. . Blockchain technology is a combination of multiple technologies. It is naturally suitable for multi-party cooperation and can provide a trusted environment for multi-party cooperation.
Application of the non-tamperable characteristics of blockchain
Bitcoin’s technical principle P2P network
Bitcoin is a P2P computer Network, each network node stores all transaction records on the network. Generally speaking, any information can be recorded on one node plus several backups. All transaction records of the network are stored on each node, which results in the transaction records being visible to each node, and each node cannot independently modify the transaction records arbitrarily, thus forming a set of open and transparent transaction records.
㈨ Comprehensive interpretation of blockchain and Bitcoin, teach you to understand the relationship between the two, and be prepared for trouble
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 is equivalent to something happening. In order to mark the occurrence of something,Students will tie a symbolic knot and record detailed information on a specific knot.
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.
㈩ What is the relationship between blockchain and Bitcoin?
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.
(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.read. For example: I lend 50 yuan to someone else. At this time, I asked the financial staff to help me keep accounts.

(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 can keep accounts. 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 a proper noun at the global blockchain technology level.
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.
(10) Blockchain protocol and Bitcoin protocol Extended reading:
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 goods based on blockchain technology.Coin central control system.
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. In the beginning, 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.
