❶ Is it good to learn blockchain?

Longlu Network is happy to answer your questions.

What is blockchain?

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.

Is there any prospect of learning blockchain technology?

The answer is yes. Big data, cloud computing, Internet of Things, blockchain, artificial intelligence, etc. are all very popular fields now and even in the next few years. Not only is our country vigorously developing, many countries around the world also attach great importance to it.

Blockchain technology helps the development of the digital economy

What skills do you need to master to learn blockchain?

Familiar with development and debugging under Linux systems, proficient in one of Golang, C++, and Java, familiar with various data structures and algorithms, and familiar with the blockchain-related mechanisms and principles of Bitcoin, Ethereum, and HyperLedger Fabric. There are many more, so I won’t list them all here. You can take a look at this reference.

What skills are needed for blockchain development?

I hope the answer from "Longlu Network" can help you.

❷ What is the relationship between blockchain and big data?

Blockchain and big data are both hot topics. Many people discuss them together and hope to conflict with more hot

points. Big data has become a huge industry long before the development of blockchain. Although blockchain is in the early stages of the

industry, many technologies and business models are still being explored.

In view of the relative maturity of the big data industry, we use big data as a starting point to study how blockchain technology interfaces with all aspects of the big data

industry.

The big data core industry chain can be roughly divided into the following three parts:

Product part: Including big data software product-related industries such as big data basic software and big data application software.

Data part: including data sources (data collection, data provision), data circulation (data transactions, data sharing

) and other industries directly related to data.

Services: Big data infrastructure services (data storage, data transmission, data cleaning, data desensitization

, etc.), big data analysis servicesServices related to big data application services.

01 Product Section

The combination of software products and blockchain should be based on technology. Big data technology and blockchain technology have similarities: they

are distributed architectures.

But they also have obvious differences: the use of distributed technology in big data technology is computing resources - utilizing the computing resources of multiple

machines and will not be used by a single machine Processing tasks are distributed among multiple computers, each

machine. By processing different tasks, it integrates multiple computing resources to form powerful data processing capabilities.

Using distributed technology in blockchain allows multiple entities to trust each other. Each mainframe participates in the operation of the entire blockchain through the computers it controls

. Each computer runs basically the same task, and the entire blockchain

can achieve mutual trust between multiple entities through repeated redundant calculations.

From a technical perspective, big data technology uses trust to exchange computing resources, while blockchain technology uses computing resources to exchange trust. Due to the differences between the two, it is technically difficult to find a suitable collision point between big data and blockchain.

02 Data Part

In the various formats of the data part, the blockchain can find its place.

The chain is of little significance. However, if multiple entities are involved in data collection and data provision, blockchain can

come into its own.

In order to solve the trust problem between multiple entities, each entity broadcasts its own collected data to all consumers

and the hash of that data Values ​​are stored in the blockchain. Based on the hash value on the blockchain, each subject in the blockchain

can verify whether the complete data it received has been tampered with. Blockchain traceability and non-repudiation

make data provided by multiple parties more credible. At the same time, this method also helps maintain the integrity of big data

.

In the data circulation industry, blockchain can play a greater role. In the big data circulation industry, big data itself

is a digital asset. The transaction of digital assets can be realized through the blockchain. In addition,

decentralized big data transactions implemented on the blockchain can reduce the original dataAccording to contact. In a decentralized trading platform, only buyers and sellers

can access the original data; on a centralized trading platform, the data intermediary serving as the trading center usually has access to the original

data. This increases data leakage and assets. Risk of Loss.

03 Service Part

In big data services, the service capabilities as digital assets are the same as the concepts of data and assets in data transactions

and Can be traded.

Blockchain can play an important role in the trading of such digital assets. At the same time, there are many new technologies that are constantly changing the blockchain, such as homomorphic encryption. Homomorphic encryption is an important technology that combines blockchain and big data services

. Homomorphic encryption can truly transform data service functions into digital assets without requiring the big data service provider to copy the original data in the service. risk.

❸ What positive effects does blockchain technology and big data have on modern society?

As two major trends in the current development of the Internet, blockchain and big data are not only beneficial to enterprises. It has a strong driving force for development and has a great positive effect on reshaping the integrity system of society.

Through blockchain, Jinwowo Group believes that blockchain can not only trace the source of every product on the platform and ensure product quality, but also record the true behavior of every user on the platform. Strengthen the integrity constraints of online behavior; moreover, through the characteristics of the blockchain itself, these behavioral data can be used reasonably and legally.

❹ Is blockchain useful? What is the impact and prospects of blockchain?

I believe everyone is no longer unfamiliar with the emerging technology of blockchain, because this is the current The most popular topic of Jiao Chun, many big guys in different industries are analyzing its role and prospects. Today we also do some research on the blockchain. Is the blockchain useful and what is the impact of the blockchain? and prospect analysis, I hope it can help everyone.
Is blockchain useful?
1. Banking: As a digital, secure and interference-proof account, blockchain realizes the core function of the banking industry: a safe storage and transfer center of value. In other words, in the next few years, a wave of companies based on blockchain technology may affect the banking industry.
2. Payment and transfer: Blockchain technology can avoid complicated systems and create a more direct payment process between the payer and the payee. Whether it is a domestic transfer or a cross-border transfer, this method has its advantages. Low price, fast, and no intermediate handling fees.
3. Network security: Although the blockchain system is public, its verification, sending and other data exchange processes use advanced encryption technology. This technique not only ensures the correct origin of the data, but alsoThis ensures that the data will not be intercepted during the process. If blockchain technology is more widely used, the probability of being attacked by hackers may also decrease, so people think that blockchain systems are more stable than traditional systems. One of the reasons why blockchain systems can reduce traditional network security risks is that they eliminate the need for middlemen.
4. Election: Everyone's vote "can never be modified or deleted by us - programmers, school administrators or students."
5. Smart contract: Smart contracts are actually on another object. A computer program that functions on the go. Like ordinary computer programs, smart contracts are also an "if-then" function, but blockchain technology enables the automatic filling of these "contracts" without manual intervention. Such contracts may eventually replace the legal merger industry's core business of drafting and managing contracts in both commercial and civil areas.
6. Stock trading: For many years, companies have been trying to simplify the process of buying, selling and trading stocks. Emerging blockchain technology startups believe they can go beyond the past, automating the entire process, improving security and efficiency.
What impact and prospects does blockchain have?
1. The dual impact of bringing wealth and risk:
The difference between blockchain technology and traditional Internet technology is that it chooses the high-risk financial industry as the entry point, but the financial field is full of Areas with many obstacles. Such direct entry has a dual impact: on the one hand, it can bring wealth effects to entrepreneurs relatively quickly; on the other hand, various risks will also come directly and violently.
2. Improve efficiency and reduce costs:
For physical finance, blockchain can maintain the fidelity in the process of transmitting information, such as personal credit information and other data, thereby avoiding many transaction costs and enabling large-scale Improve efficiency, this is the positive meaning it brings.
3. Control financial risks early and small:
Blockchain is cooperating with the innovation of digital currency, preventing over-insurance in the insurance industry, over-lending in bank mutual funds loans, and the integration of supply chain finance. , promote electronic identity recognition, etc., applicable to many industries and fields. In terms of financial security, many companies have also cooperated with regulatory authorities to build regulatory technology systems to help regulatory authorities monitor and provide early warning for the risks of Internet financial companies, so as to control financial risks early and at an early stage.
4. The owner of the data should be the user himself:
Blockchain is a technology worthy of attention, and it has relevant layouts in its own business and investment. Bitcoin and other electronic currencies are applications based on blockchain technology. They have certain currency functions and have certain use value. However, the main problem now is that the gap between the use value and the transaction price is too big. . ICO is a financing business model.
5. The darkest stage contains the most opportunities:
The darkest stage often contains the most opportunities. The application of blockchain is far more than just monetary and financial. For example, big data can be applied to the entire medical industry in the future. health field. likeIf medical records and diagnosis data are shared to all different medical systems through the big data blockchain, the efficiency of treating diseases and saving lives can be greatly improved.
The editor believes that the correct development prospect of blockchain is to "talk less about financial innovation, focus more on financial security, focus more on inclusive finance, and do more on medical care, health, and environmental protection."
The above is the blockchain brought to you by the editor. Is it useful? What impact and prospects does blockchain have? all content.

❺ Blockchain development or big data development, which one tests coding skills more

Big data development.
Da Shu Zen data development requires Kaiyun to process massive data and be proficient in distributed computing, data mining, machine learning and other technologies. Big data development requires processing different types and formats of data, and performing data cleaning, conversion, aggregation and other operations; therefore, big data development requires a high level of coding skills.
Blockchain development refers to the use of technology to build and maintain distributed databases, systems that can be used to store and manage data.

❻ Is it safe to apply blockchain technology to big data?

The answer to this question is yes, because a big feature of blockchain technology is that the information cannot be tampered with , 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 can be controlled at the same time, modifications to the database on a single node are invalid, so the data in the blockchain Extremely high stability and reliability. For example, Jinwowo Group can provide big data services with blockchain as the underlying technology. Its encryption technology can fundamentally ensure the security and storage of data.
