① Popular explanation of what blockchain is

Blockchain is essentially a decentralized distributed ledger database. The blockchain uses algorithms related to cryptography to generate data blocks, and each data block records information confirmed by multiple Bitcoin network transactions.

To put it simply, the blockchain is like a ledger, and each block that makes up the blockchain is each page of the ledger. The details of the transactions are recorded in a public ledger that can be seen by anyone on the network.

Blockchain uses cryptography to ensure that existing data cannot be tampered with. There are two core points in this part: cryptographic hash values ​​and asymmetric encryption.

② What is blockchain? The simplest explanation of blockchain.

Blockchain is a decentralized distributed ledger database. This distribution The advantage of a digital ledger is that buyers and sellers can trade directly without any intermediary. Everyone has a backup, even if yours is lost, it will not be affected.
If you have a ledger at home, let you keep it. In the past, your parents gave you your salary and asked you to record it in your account book. If you are greedy and want to buy something delicious in the meantime, the record in the account book may be missing by more than ten yuan, and no one else will know.
How to use blockchain to solve problems: If you use the whole family mobilization method to keep accounts, the above-mentioned problems will not exist, because you are keeping accounts, your father is also keeping accounts, and your mother is also keeping accounts. , they can all see the general ledger. You can’t change it, and neither can your parents. In this way, your father who wants to buy cigarettes and you who want to eat can’t do anything about it.

Blockchain application fields
1. Financial field
Blockchain is used in finance such as international exchange, letters of credit, equity registration and stock exchanges. The field has potential huge application value. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.
2. Internet of Things and Logistics Fields
Blockchain can also be naturally combined in the Internet of Things and logistics fields. 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. This field is considered to be a promising application direction of the blockchain.
3. 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.
4. Insurance field
In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have higher management and operating costs. Through the application of smart contracts, there is no need for the policyholder to apply or the insurance company to approve it, as long as the claim settlement clause is triggeredsoftware to realize automatic claim settlement for insurance policies.

③ What does blockchain mean? One article will teach you how to understand blockchain

According to Xinhuanet: On the afternoon of October 24, 2019, the Political Bureau of the CPC Central Committee The 18th collective study session was conducted on the development status and trends of blockchain technology.

When organizing this study, Xi Jinping said: "The integrated application of blockchain technology plays an important role in new technological innovation and industrial transformation. We must use blockchain as a core technology An important breakthrough for independent innovation, clarify the main direction, increase investment, focus on conquering a number of key core technologies, and accelerate the development of blockchain technology and industrial innovation."

"Blockchain" for a time This word has become popular all over the Internet. People with a software development background may have a certain understanding of blockchain technology, but most of us are ordinary people. As ordinary people, when faced with the term "blockchain", it is full of questions. Questions, what does blockchain mean, what does distributed ledger represent, and what is the difference between centralization and decentralization?

The Internet defines blockchain as: 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 an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each The data block contains information about a batch of Bitcoin network transactions and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

Simply speaking, blockchain is a decentralized database.

This is the function of distributed accounting. Distributed accounting brings benefits and convenience to our lives.

In real life, "blockchain" technology can be widely used in medical care, travel consumption, financial payment and other fields in the future. It will bring convenience to people’s lives, and at the same time, it will also comprehensively improve our financial environment and medical environment.

④ An easy-to-understand explanation of blockchain

A simple explanation of blockchain technology is as follows:

To put it simply: blockchain is the use of a package of existing A new generation of network system formed using advanced network technology. This network system has a new structure, a new mechanism, and unprecedented new value. Five major technologies or innovations are specifically used: encryption technology, P2P network technology, distributed storage technology, consensus mechanism, and smart contracts.

Essentially: it is a shared database, and the data or information stored in it is "unforgeable", "full-process traces", "traceable", "open and transparent" and "collectively maintained" ” and other characteristics. Based on these characteristics, blockchain technology has laid a solid foundation for "trust-based sales" and created a reliable "cooperation" mechanism. Yunchun has broad application prospects.scene.

2. Openness.

In addition to the encryption of private information of all parties to the transaction, the blockchain data is open to everyone and provides a flexible script code system. The entire system information is highly transparent and within the rules specified by the system. Nodes cannot deceive each other.

3. Autonomy.

Consensus technology, smart contracts.

⑤ What is blockchain

In the simplest terms, blockchain is a distributed ledger.

To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology started with finance, we will also introduce it below using banks as an example.

The following is our process for using bank debit card transactions:

You can swipe your card to purchase goods in stores.

The merchant sends a statement to your bank for the agreed upon amount.

Your bank will verify that you may have authorized the purchase.

The bank sends the money to the merchant.

Finally, the bank records this information in its ledger.

There’s a lot of technology involved here, but that’s basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.

This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.

Crucially, if hackers were able to access a bank’s ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.

This is why distributed ledgers are so cool.

Blockchain Network Visualization

If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledger, and whenever any member of the bank When they make a purchase, they tell every other member of the bank.

Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem because other ledgers can easily verify it.

On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).

As mentioned above, blockchain is a decentralized list of transactions. If I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying"I'm sending Xiao Ming 2 Bitcoins" and they will both record the transaction.

The future of blockchain, how will it change our lives?

One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.

Blockchain is not just science fiction. We don’t need to understand the mechanism behind this technology, but you do need to understand that it may completely change our lives in the next 20 years.

This may sound bold, but remember, 20 years ago we were browsing the Internet on Netscape, using state-of-the-art Motorola flip phones, and buying our first DVD players. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.

Although the impact of blockchain may not be as obvious as the Internet, nor as tangible as mobile phones, blockchain will effectively solve many worries in daily life. Such as intermediaries cheating people, transaction delays, etc. In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world will become a different place.

Imagine that by 2040, blockchain may become a mature and widely used technology. When one day you can't live without the blockchain just like you can't live without the Internet now, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle

⑥ What is blockchain

From a scientific and technological perspective, blockchain technology involves many scientific and technological issues such as mathematics courses, cryptographic algorithms, big data technology and computer programming. From an application perspective, to put it simply, blockchain is a resource sharing ledger and database of a distributed framework, which has the characteristics of decentralization, inability to forge, traces of the entire process, traceability, collective maintenance, openness and transparency.

Based on this characteristic, blockchain technology establishes a reliable "trust" foundation and creates a reliable "collaboration" system, which has broad value. In recent years, the world's attitude towards Bitcoin has been ups and downs, but blockchain technology, as one of the basic technologies of Bitcoin, has received more and more attention. In the Bitcoin generation process, a block is a storage unit that records all information exchanges of each block node within the corresponding time period. The intermediate links between each block are achieved according to random distribution (also known as hash algorithm), and the subsequent block contains the hash value of the subsequent block. As the exchange of information expanded, 1 block and 1 block continued, and the result became known as blockchain technology.

Blockchain technology, as an auxiliary technology, does not decentralize the entire energy network, but makes the energy network more closely connected. Each network can be "autonomous" while maintaining independence. This independence can Improve the work efficiency of each outlet, and at the same time reduce the work efficiency of each outlet.Operating efficiency reduces energy losses in “intermediate links”.
