A. Which of the following options is not a characteristic of blockchain

Centralization

Decentralized, Trustless, Collective Maintenance (Collectivelymaintain), reliable database (ReliableDatabase).

B. The core technologies that are not part of the blockchain include

First of all, we can take a look at the official website explanation of 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.

C. The technical characteristics of blockchain include: (). a decentralized b traceable c open and transparentMingd cannot be tampered

The technical characteristics of blockchain include decentralization, non-tampering, consensus trust mechanism, openness, anonymity, cross-platform, etc.

6. Cross-platform

Similar to the TCP/IP protocol of the Internet, blockchain can also be regarded as a basic communication protocol. The cooperation of other mechanisms together constitutes the value Internet based on blockchain. Nodes on the blockchain network operate independently based on common algorithms and data structures. They mainly consume computing resources and have nothing to do with the platform. Computing nodes can be deployed on any platform.

It can be said that the characteristics and development of blockchain come from the soil where it was born - the development of Internet technology and the rise of cloud computing and big data.

D. Characteristics of blockchain

1. Decentralization

The so-called decentralization Centralization means that because the blockchain uses distributed computing and storage, there is no centralized hardware or management organization. The rights and obligations of any node are equal. The data blocks in the system are maintained by the entire system. nodes to jointly maintain.

2. Openness

The so-called openness means that the blockchain system is open. In addition to encrypting the private information of the transaction parties, the blockchain data is open to everyone. Public, anyone can query blockchain data through the public interface and develop related applications. The information of the entire system is highly transparent.

3. Autonomy

The autonomy feature of blockchain is based on specifications and protocols. The blockchain adopts consensus-based specifications and protocols (such as open and transparent algorithms), so that all nodes in the system can freely and securely exchange data in a trustless environment, changing trust in "people" to machines. trust, no human intervention can work.

4. Information cannot be tampered

< p>The so-called information cannot be tampered with, that is, once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system are controlled at the same time, modifications to the database on a single node will be invalid.

Because of this, the stability and reliability of blockchain data are very high. Blockchain technology has fundamentally changed the centralized credit creation method, using mathematical principles rather than centralized credit institutions. To establish credit at low cost, birth certificates, real estate certificates, marriage certificates, etc. can be notarized on the blockchain, with a global central node, becoming something that is trusted by the world.

5. Anonymity

The so-called anonymity means that the exchange between nodes follows a fixed algorithm. The data interaction does not require trust, and the counterparty does not need to disclose its identity. The other party has trust in you, which is conducive to the accumulation of credit.

Lianxin has tens of millions of membersThe user's blockchain application has its own Quark blockchain as a public chain, qkibill open source wallet, and independent block browser. It is a completely independent blockchain platform where users control their own data. Quark Chain Innovation Zone The blockchain plus life service platform is committed to creating better blockchain services. The Lianxin blockchain has the above characteristics and is a real blockchain project.

E. Which of the following is not a feature of blockchain technology

It is not a feature of blockchain technology that any blockchain has super administrator privileges. Blockchain is a shared distributed database technology. Its advantages are mainly reflected in three aspects: distributed decentralization, trustless system and non-tampering and encryption security.

F. The characteristics that are not part of the blockchain are

high efficiency
