『一』 Which of the technologies used by blockchain does not include?

The technologies used by blockchain do not include big data

area Blockchain technology includes distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other technical applications. It was developed based on needs after market research by experts, sports experts and the operation team.

2 Public blockchain The public blockchain is the earliest blockchain and the most widely used blockchain at present.

3 The alliance chain designates multiple pre-selected nodes within a certain group as bookkeepers, and the generation of each block is jointly decided by all pre-selected nodes. Other access nodes can participate in transactions, but are not involved in the accounting process (it is essentially still managed accounting, but becomes distributed accounting. How many nodes are pre-selected, and how to determine the bookkeeper of each block to become the blockchain Main risk point), anyone else can make limited queries through the API opened by the blockchain.

『二』Which technology does blockchain use not include ( ) A cryptography B big data C P2P network D consensus algorithm

Blockchain is a distributed What it wants to do with shared accounting technology is to enable all parties involved to establish a trusting relationship at the technical level. 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. The core of blockchain...

『三』 The classification of blockchain does not include

Excluding alliance chains, blockchain is divided into three categories, the first It is a public chain, which refers to a blockchain like the Bitcoin blockchain that is completely decentralized and not controlled by any organization. Any individual or group in the world can send transactions, and transactions can obtain the blockchain. Valid confirmation, anyone can participate in its consensus process.

The second is the alliance chain. The so-called alliance chain refers to a group that designates multiple pre-selected nodes as bookkeepers. The generation of each block is jointly decided by all pre-selected nodes. Other access nodes can participate in transactions, but are not involved in the accounting process. Anyone else can make limited inquiries through the open API of the blockchain.

The third is private chain, which refers to the use of distributed accounting within a company or unit. We see that these three classifications are actually classified according to the form of the management center.

Blockchain Characteristics

1. Decentralization. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes self-verification, transmission and management of information through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain.

2. Openness. The foundation of blockchain technology is open source. In addition toIn addition to the private information of all parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface, so the entire system information is highly transparent.

3. Independence. Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), 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 the need for any human intervention.

『四』 Which of the technologies used by blockchain does not include?

The technologies used by blockchain do not include big data

1. P2P network technology

In fact, before the emergence of blockchain, distributed P2P peer-to-peer network was already a very mature technology.

2. Encryption technology

In terms of encryption technology, blockchain uses an asymmetric encryption algorithm.

3. Smart Contract

The term "smart contract" was first proposed by legal scholar Nick Szabo in 1995.

4. Consensus Mechanism

In the past, we paid an extremely expensive price for trust, and blockchain will incredibly change this situation.

Blockchain is revolutionizing various ways to pay for e-commerce:

1. Faster payment processing

2. Easily process receipts and warranty vouchers< /p>

3. Self-executing smart contracts

4. Reduce handling fees

5. Prevent network attacks

『Wu』 Blockchain What non-monetary application scenarios do not include

The non-monetary application scenarios of blockchain do not include financial investments and transactions, virtual currency mining and currency-related activities.
1. Financial investment and trading. Financial investment and trading involve a large amount of capital flow and risk management, and require more stringent supervision and legal support. Due to the decentralization and anonymity of blockchain technology, it cannot provide sufficient regulatory and legal protection, so its application prospects in the fields of financial investment and trading are relatively limited.
2. Virtual currency mining. Virtual currency mining is an act of obtaining virtual currency through computer calculations. Since this behavior involves the generation and circulation of currency, it also requires more supervision and legal support. In addition, the value of virtual currency is extremely unstable, which also brings great risks and uncertainties to virtual currency mining.
3. Currency-related behaviors, in the fields of financial investment and transactions, as well as in the process of virtual currency mining, involve issues of user identity authentication and data privacy protection. However, blockchain technology has not yet solved these problems, so its application in these fields is subject to certain limitations.

『Lu』 What is not the core technology of the blockchain is

What is not the core technology of the blockchain is the network protocol. Blockchain core technologyTechniques include: Distributed ledger means that transaction accounting is completed by multiple nodes distributed in different places. Each node records a complete account and can participate in supervising the legality of the transaction and can also jointly testify for it.

『撒』 The core technologies that are not part of the blockchain are

First of all, we can take a look at the official website explanation of the blockchain technology. In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed distributed ledger that cannot be tampered with or forged. .
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 paradigm that uses smart contracts composed of automatically encoded script codes to program and operate data.
As everyone may know, blockchain technology is an underlying architecture independent of the Bitcoin system. From an architectural model perspective, it is a set of distributed ledgers. The so-called ledger is naturally used to record Account.
In blockchain technology, in order to generate accounting records, there must be transactions and flows of funds. Therefore, the initial blockchain technology has the cryptocurrency corresponding to its main network as a circulating item. , the circulation transaction records of cryptocurrency between various accounts on the blockchain main network will be recorded on the main network.
Different from other transaction record databases, transaction records on the blockchain technology mainnet will be recorded on all block nodes (i.e. all data blocks) in the mainnet. This is the so-called decentralization principle. That is to say, in blockchain technology, there is no central database to save all records. Each block on the chain has the transaction data of the entire chain. In other words, each block has transaction data of the entire chain. A block of data is all centered.
Another characteristic of blockchain technology is that it cannot be tampered with, because every transaction on the blockchain will be recorded in all blocks on the chain, so no single data block can be changed. Record, even if you change it, the real data will be recorded in all other data blocks, and each set of data can be traced back to when it first appeared.
Because of these characteristics of blockchain technology, after the advent of Bitcoin, blockchain has also received a lot of attention, and many people have begun to want to use blockchain technology to create a centerless and traceable system. , data that does not change to ensure the credibility of the data.
However, blockchain technology also faces many problems, such as a single application scenario, native erroneous data that cannot be modified, and currencies stolen by hackers that cannot be recovered.

『8』 What is not a key technology of blockchain is

VPN technology. According to the query of relevant information, the key technologies of blockchain include: distributed storage, cryptography, consensus mechanism, smart contracts, and no VPN technology.
