❶ Can anyone explain what blockchain is in a simple way?

Blockchain is the underlying technology of Bitcoin. It is like a ledger that records all transactions. Transaction Record. It is decentralized. What is decentralization? For example, when you buy something on Taobao, you place an order and pay in Alipay. Alipay will not transfer the money to the seller until you receive the goods. Alipay is the third party in that center. Without it, it means decentralization, just like buying things offline. If you pay with one hand and get the goods with the other hand, there is no third party.

The blockchain itself is a series of cryptographically related data blocks generated.

Look carefully to see if it looks like a ledger. The pieces one by one are blocks, and connected together they are the blockchain.

Many companies are developing this technology, and so is our company. Its prospects are limitless. For details, you can go to our official website and hope to adopt it, thank you

❷ Easy-to-understand explanation of blockchain

A simple explanation of blockchain technology is as follows:

To put it simply: Blockchain is a new generation network system formed using a package of existing network technologies. 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.

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.

❸ What is blockchain video

Blockchain is a distributed shared accounting technology. What it wants to do is to enable all parties involved to Build trusting relationships. Blockchain can be roughly divided into two levels: one is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, the transformation, optimization or innovative application based on the blockchain. What is the core meaning of blockchain? Our understanding is that the core meaning of blockchain is to establish data credit among participants, and through unilateral confrontation, create a complete opportunity for unilateral ecological joint protection under clear regulations. , this is a system. This kind of establishment can end the problems before the blockchain. Before the blockchain, it was impossible to achieve new sharing when sharing data. Even if it was oriented, it would only give you an interface. pieceAfter the chain is established, the participants can realize the sharing of credit.
Blockchain has been applied in several fields. In the first field of digital assets, in addition to some points and check-in cards we have seen, it also includes various other assets, and there is a process of asset digitization. For example, the tokens of different crowdfunding projects on the Biying China platform.

The second field is the field of trade finance. Because the field of trade finance is originally a multi-link and multi-party participation method, blockchain can greatly improve the efficiency of the middle, making many substitutes. Effect.

The third area uses equity, which is company equity like some regional equity trading centers. The purpose is to facilitate equity-to-transaction and facilitate relative circulation. At present, the multi-center blockchain system can indeed improve efficiency and reduce costs.

❹ What is Blockchain

In the simplest terms, a 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 the recordslimit. 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 am sending Xiao Ming 2 Bitcoins" and they all 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

❺ What is blockchain? Explanation of blockchain technology

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.

At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify its Validity of information (anti-counterfeiting) and generation of the next block.

The blockchain is a public data list, and each record in it is called a block. These blocks are connected together like a chain to form a blockchain. Just like an idiom solitaire, there must be some connection between adjacent words to form a word chain. The same is true for blockchain, onlyBut the connection between blocks is much more complex.

Blockchain technology innovation does not mean speculating on virtual currency, and the use of blocks should be prevented Chains issue virtual currencies and speculate on air coins. At the same time, we should also note that blockchain is still in its early development stage and needs further development and improvement in terms of security, standards, supervision, etc.

The general direction is not wrong, but it is necessary to avoid rushing in and duplicating construction, and to open up the imagination space of the blockchain in orderly competition. China has a good foundation in the field of blockchain. Some large Internet companies have already laid out their plans. The talent pool is relatively sufficient and the application scenarios are rich. It is fully qualified to achieve a leading position in this new track.

From a larger perspective, human beings can develop civilization because they have achieved effective cooperation among large-scale groups of people. The "invisible hand" explained by Adam Smith also realizes the division of labor and cooperation in human society through the market mechanism.

From this perspective, blockchain has greatly expanded the breadth and depth of human trust and collaboration. Perhaps, blockchain is not only the next generation of Internet technology, but also the next generation of cooperation mechanisms and organizational forms.

Comprehensive interpretation of blockchain technology

For the market When it is generally believed that blockchain technology is just a technology, the blockchain team of Ant Financial Technology Lab gave a calm explanation: blockchain technology itself is not a specialized technology, but is integrated by many previous technologies. , for example, it includes P2P networks, numerous nodes, cryptography, and some things similar to consensus. So from this point of view, if we purely use previous technologies, blockchain technology will almost be formed in the end.
