Ⅰ Comprehensive interpretation of blockchain and Bitcoin, teach you to understand the relationship between the two, and be prepared for trouble

When talking about blockchain, "Bitcoin" is often inseparable ", because today's cryptocurrencies are all issued in the name of blockchain, some people can 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 record detailed information on the specific knot.

Bitcoin uses the 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 the "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.

So, for an emerging technology,It is best not to trust or invest blindly, but only by recognizing its true purpose can you see everything objectively and be prepared.

Ⅱ What is the popular explanation of blockchain? You must know these five application scenarios of blockchain!

Recently, blockchain has become popular overnight, and everyone around is discussing blockchain.

So, is the blockchain the same as Bitcoin?

In fact, Bitcoin and blockchain are not the same thing.

Blockchain is the underlying technology of Bitcoin, but the first usage scenario after the birth of blockchain is Bitcoin.

Bitcoin is just a string of data in a computer. Compared with paper currency, it is also called a "virtual currency". To put it simply, you can understand that Bitcoin is just a string of numbers with cash value, similar to Q coins. In other words, Bitcoin has no actual value. Its current value is supported by the faith of currency speculators. If the faith is gone, the value of Bitcoin will collapse.

What is blockchain? What are the characteristics of blockchain technology?

Let’s first take a look, why is blockchain called blockchain?

Data is stored piece by piece, and the data stored piece by piece is called a block. Different blocks are linked to the previous block, which is called a blockchain.

For example:

On a certain day of a certain year, Lao Wang lent Xiao Wang 10,000 yuan, and Lao Wang told everyone around him the news , the transfer records were posted on WeChat Moments, and everyone helped them testify to the existence of this transaction.

Lao Wang and Xiao Wang are two nodes. These two nodes generate transaction time, location, person and other information, and they are packaged to form a "block". Lao Wang’s friends are also nodes. These nodes jointly record the transaction status and details (blocks) of the two nodes Lao Wang and Xiao Wang. These blocks are connected to form a blockchain.

Fundamentally, blockchain is a distributed ledger database.

What does distributed ledger mean?

Let’s take a look at the traditional accounting method.

The traditional accounting method is a centralized accounting method. For example, if Lao Wang lent 10,000 yuan to Xiao Wang, if Lao Wang did not tell the world about this money, then this amount would Only Lao Wang knows about the money transactions, Xiao Wang knows, God knows, and Earth knows. This accounting method is a centralized accounting method. This method has a very fatal shortcoming: what should I do if the other party does not acknowledge the account? In fact, in real life, in spontaneous private lending relationships, there is no evidence when the lending relationship occurs, resulting in many cases where the other party does not acknowledge the debt afterwards.

The accounting method adopted by Lao Wang from the beginning has prevented future troubles. This method is the blockchain distributed ledger, which has the characteristics of decentralization and everyone is a Center, everyone can testify to the existence of this deal.

In addition to the characteristics of decentralization, blockchain also has the characteristics of being immutable. In the blockchain, if the data in any one block changes, even if it only changes a punctuation mark, it will become invalid and needs to be recalculated. Therefore, in the blockchain technology, once a piece of data changes, the cost will be Very big. Unless all nodes in this blockchain have 51% control. Therefore, the blockchain system will be stable and secure.

It’s still Lao Wang and Xiao Wang. If Xiao Wang wants to default on his debt, he can’t tamper with it unless he bribes everyone in the world who knows about the transaction.

Blockchain is also open and transparent.

In blockchain technology, all data is public, which is still the case of Lao Wang and Xiao Wang.

If Xiao Wang does not acknowledge the money, once this news is released, then Xiao Wang’s reputation will be ruined. He can only release new news and wash away the money by paying back the money. Clear your own identity.

Some people say that if the blockchain is so powerful, will my identity information be revealed and there will be no privacy? In fact, the blockchain has the characteristics of anonymity and protects our privacy very well. Unless required by legal regulations, technically speaking, the identity of each block node does not need to be disclosed or verified and can be done anonymously.

What are the applications of blockchain?

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.

In addition to digital currency, the future applications of Bitcoin are still very wide, and 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

The role of the intermediary bank can be abandoned, point-to-point payment can be realized, intermediary fees can be reduced, and fund utilization can be accelerated.

2. Product traceability

For example, if we buy a piece of clothing on a certain website, 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.

Ⅲ What is the concept of blockchain

Literally understood, blockchain includes two concepts: block and chain. The blockchain itself is composed of blocks, and the network built by linking different nodes together is the blockchain. The main function of the blockchain is to store information. Any information that needs to be saved can be written to the blockchain or read from it.

Each block stores: some valid record or transaction; information involving the block; links to the previous block and the next block through the hash of each block - which can be considered a block The unique code of the fingerprint.

Each block therefore has a specific and immovable position within the chain, as each block contains information from the hash of the previous block. The entire chain is stored in every network node that makes up the blockchain, so an exact copy of the chain is stored among all network participants.

Uses

Essentially, blockchain can be used to store any type of information that must remain intact and be more secure than going through a middleman. , decentralized and cheaper ways remain available. Additionally, since the stored information is encrypted, its confidentiality is guaranteed as only those with the encryption key can access it.

Using blockchain in healthcare. For example, health records can be consolidated and stored on the blockchain. This means that every patient's medical history is secure and, at the same time, available to every authorized doctor, regardless of the health center where the patient received treatment. Even the pharmaceutical industry could use this technology to authenticate medicines and prevent counterfeiting.

Blockchain is also very useful for managing digital assets and documents. The problem with digitization so far has been that everything is easily copied, but Blockchain allows you to record purchases, deeds, documents or any other type of online asset without it being counterfeited.

IV What is the popular explanation of blockchain? Did blockchain originate from Bitcoin?

1. Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust", created a reliable "cooperation" mechanism, and has broad application prospects.

2. Blockchain originated from Bitcoin. On November 1, 2008, a person claiming to be Satoshi Nakamotoo) published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on the architectural concept of an electronic cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., which marked the The birth of Bitcoin. Two months later, the theory came into practice, and on January 3, 2009, the first genesis block with serial number 0 was born.

IV Blockchain does not necessarily have to issue coins, but public chains must issue coins

Some countries have been advocating "coinless" blockchains. It just wants the chain but not the currency. It supports technology development but does not support the issuance of currency.

What are the categories of Tokens?

Answer: Three categories

The first category: the lowest level, the so-called junk Tokens. For example, there are various air coins. There are many such tokens in the current market. Everyone needs to keep their eyes open when investing.

Category 2: Ordinary Token. There are now a few implementation projects in progress, such as membership coins, point coins, etc. What everyone thinks about this is a matter of benevolence and wisdom. Some people think it's worth investing, others think it's pointless.

The third category: the most valuable is the value Token. These have investment value.

Tokens with investment value are at least three rights in one.

1. Property rights represent the right to use and deliver products or services. This is the basis that people can use.

2. Currency attribute, it can be circulated, at least it is hard currency within the ecosystem. This is the basis that people are willing to hold on to.

3. Equity attributes: it can increase in value, long-term returns can be expected, and the room for appreciation is large. Blockchain is not just a technology, it is a new way of production and organization, and even a new way of thinking.

Do blockchain projects have to issue coins?

Answer: No need to issue coins

Not all blockchain projects must issue coins. , and the one issuing the currency is not necessarily a blockchain project. For example, in the alliance chain, there is no need to issue coins. For example, Tencent's Q coin is, in principle, a currency, but it is not a blockchain project.

Does a public chain necessarily need to issue coins?

Answer: It must issue coins

Let’s take Bitcoin as an example. As a public chain, the Bitcoin system must rely on the existence of coins. The public chain obtains the stability and non-tamperability of its system through nodes distributed around the world, and these properties are the basis for the survival of the public chain.

Just imagine, if the Bitcoin system is unstable or can be easily tampered with, Bitcoin will be worthless. These nodes are notIt is established by one or several companies, otherwise it is equivalent to a private chain or alliance chain. These nodes must be dynamically constructed by many participants. The existence of these nodes must require the existence of some kind of incentives, otherwise why would the builders of these nodes participate in your system. And this incentive must be integrated with the blockchain system and must be a currency.

Token must be used as an incentive. Isn’t it possible to use RMB?

Answer: No

If RMB is used as an incentive, RMB must be stored in a RMB account. , and this account itself is centralized and too easy to be controlled. If you think about it, you will understand why domestic Bitcoin exchanges are so afraid of central banks, for fear of being weaned. In addition, the RMB cannot chemically react with the smart contracts within the blockchain.

And only by reasonably stimulating output through tokens can production relations be changed and the value of the blockchain be brought into play. TOKEN can promote the development of projects faster. TOKEN solves the problems of incentives and consensus. Incentives solve the problem of autonomy. The positive autonomous economic ecosystem and the underlying technology of the blockchain are a perfect combination.

Therefore, public chain projects must have coins. Public chain projects without coins are like an incomplete life.

VI There is no need for Bitcoin in the blockchain

The relationship between the two should not be black and white. Look at how many people admired Satoshi Nakamoto’s peer-to-peer system. Binance’s blockchain and centralized platform also exist very well without interfering with each other.

VII 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.

(7) Does the blockchain have to have Bitcoin? Extended reading:

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. No matter where you are, anyone can dig, buy, sell or receive Bitcoin.

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 remit 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.

VIII What is the relationship between blockchain and Bitcoin

Blockchain technology is Bitcoin The basic technology 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 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 the "blockchain" in the original English version of the Bitcoin white paper. 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.

(8) Does blockchain require Bitcoin? Extended reading:

Blockchain applied to digital currencies 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.

Ⅸ 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?

We learn fromLet’s look at it from a technical 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. The 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 Xiao Li was selling paper boxes and buying some public items in the dormitory,All will be recorded 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 the great benefits of blockchain, in a short period of time, the prices of blockchain-related assets have soared, and ordinary investors are becoming more and more interested in blockchain. And criminals have also taken aim at this. There are some criminals who put on the gorgeous cloak of "blockchain" and use the blockchain to commit fraud or issue digital currencies without permission, causing 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 Moubao, the product 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.

Okay, what about blockchain?This is where I will introduce you to the relevant knowledge about the concepts. I hope it will be helpful to you.
