Difference Between Quantum Algorithm and Blockchain

① What is the difference between blockchain and Bitcoin, and what is their relationship?

Bitcoin is an application direction of blockchain, that is, blockchain is the foundation, understand?

② The difference between Bitcoin’s blockchain and other blockchains

In the Bitcoin system, the most important thing is not the concept of “coin”, but a non-central storage mechanism “Ledger” concept. A “coin” is just the unit of account used on this ledger. It can be said that Bitcoin is essentially an Internet-based decentralized ledger, and blockchain is the name of this ledger. Here we can make an image analogy. If the blockchain is a physical ledger, a block is equivalent to a page in the ledger, and the information carried in the block is the transaction content recorded on this page.
Blockchain is the core and infrastructure of Bitcoin, a decentralized ledger system.
Since the blockchain is a ledger, how is this ledger different from our traditional ledger? We know that the content on the ledger must be unique, which leads to the natural centralized behavior of bookkeeping. This is true in the era of underdeveloped means of communication, and it is also true in today’s information age. However, centralized bookkeeping has some obvious weaknesses: once there is a problem with this center, such as being tampered with or damaged, the entire system will face a crisis or even collapse.

③ What is the relationship between blockchain and Bitcoin

Blockchain technology is the underlying technology of Bitcoin, as well as the core and infrastructure of Bitcoin. Bitcoin has been running without any centralized organization operation and management. Later, Bitcoin technology was abstracted and called blockchain technology, or distributed ledger technology.

Disadvantages of applying blockchain technology to digital currency:

First, there is no circulation management agency for “decentralization”. Blockchain technology is essentially a distributed database system, the logical structure is a singly linked list, and the design mode is based on the P2P network, which determines that the virtual currency based on blockchain technology does not have a unified central control system.

Secondly, it is difficult to effectively control the quantity supply. The issuance of virtual currency based on blockchain technology is fixed, and according to the Fisher equation, the total transaction volume at a certain price level in the whole society in a certain period of time has a certain proportional relationship with the required nominal currency volume, and the constant currency volume is obviously Can not meet the ever-increasing total social commodity price requirements.

Third, it is difficult for the “mining mechanism” to create recognized value. Bitcoin itself has no value and no national credit support. There is a view that “injecting value into virtual currency by continuously consuming computing power and energy”, but it is obviously not the most efficient choice to consume trillions of calculations to find a hash value that meets the requirements.

Fourth, producers and early holders can easily get high “seigniorage”. Any virtual currency based on blockchain technology is held by a small number of people in the initial stage of its development. Take Bitcoin as an example. Initially, Bitcoin was only the product of a few people’s games. The first Bitcoin purchase occurred in May 2010. 10,000 BTC bought a $25 pizza, and the first Bitcoin transaction was completed in July of the same year. It is $0.04/BTC.

④ The difference between the code chain and the blockchain

The difference between the code chain and the blockchain:
The blockchain is derived from the underlying technology of Bitcoin and is the Blockchain technology. The IP is connected in a block-by-block manner through blockchain technology to form distributed accounting. It has the characteristics of not easy to tamper with and decentralization.
Code chain technology is the code chain technology of the Internet of Things, which superimposes the Internet of Things IDs one by one in a two-dimensional manner to form a personal record. The use of “code chain” technology will bring more efficient link forms of “people and people Internet”, “people and Internet of Things”, and “things and Internet of Things”.
Introduction to Code Chain:
“Code Chain” refers to using a smartphone to align the “QR code” and “scan” to “generate a new QR code containing the scanner’s DNA” ”, and the “QR code chain” formed by accessing the “service” at the same time. The whole process can be traced, supervised and managed.
The most widely used “code chain technology” is the two-dimensional code “scan and scan” payment technology.
Code chain technology can realize a more efficient link form between people and people, people and things, and things and things.
Blockchain Introduction:
Blockchain is an important concept of Bitcoin. A blockchain is a series of data blocks that are associated with cryptographic methods. Each data block contains the information of a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner according to time sequence, and is encrypted with a password.An immutable and unforgeable distributed ledger guaranteed by the �� way.
In a broad sense, blockchain technology is the use of blockchain data structures to verify and store data, use distributed node consensus algorithms to generate and update data, and use cryptography to ensure the security of data transmission and access. A new distributed infrastructure and computing paradigm that utilizes smart contracts composed of automated scripting code to program and manipulate data.
The difference between the code chain digital currency and the blockchain digital currency:
The difference between the “Code chain digital currency” based on the code chain technology and the existing blockchain digital currency is that “Code chain digital currency” “Digital currency” is based on the control of property rights and uses “smart QR code” as the medium to convert the contracts of various industrial chains into divisible, tradable, transferable, convertible and traceable “smart contracts”, and Property rights can be exchanged within the code chain alliance. In the code chain currency system, “smart QR code” is “special mentioning right SGR”. That is, each product corresponds to a “smart QR code”, and this “QR code” represents the “special mentioning right” of the product. Through the exchange of special mentioning rights, the exchange of goods and goods (barter) is realized. This QR code, which represents the “special mentioning right”, can be used as a carrier of digital currency and a means of payment at the same time, and payment can be completed through “QR code scanning”.

⑤ What is the relationship between digitization and quantum technology

The Politburo of the CPC Central Committee held the 24th collective study on the research and application prospects of quantum technology on the afternoon of October 16, which is the next After big data, artificial intelligence, and blockchain, the Political Bureau of the CPC Central Committee has once again focused on the frontier science and technology fields. Quantum technology itself is one of the core contents of digital technology and the core force to promote the era of digital economy.

What is quantum? Quantum is an important concept in modern physics, referring to the smallest and indivisible basic unit of a physical quantity, which is fundamentally different from classical physics represented by Newtonian mechanics .

Quantum technology has become a hot word for a while, and there are also a lot of searches and interpretations for the keywords “quantum science” and “quantum communication” on the Internet. Do not confuse these three words. “Quantum science” refers to the effect of quantum in science and is a subject system of quantum information; “quantum communication” refers to the application of quantum in the field of communication, that is, encrypting communication to ensure security, although communication is quantum A very important application of technology, but quantum communication cannot be equated with quantum technology itself.

Compared with some improved technologies in the scientific community, quantum technology has a subversive effect. What it subverts is the electronic computing that currently occupies the mainstream position, that is, traditional and mainstream computers still use electronics as the basic The carrier is a computer based on the von Neumann structure, and the electronic components of the mainstream computer, the chip, are also based on electronics and develop in accordance with the economic laws of Moore’s Law. nanometer development to 5 nanometers.

But the problem is that Moore’s Law is now approaching the physical limit, so there is an urgent need for some disruptive technologies in the field of science and technology, using quantum as the basic computing unit, and innovating the computing architecture with electrons as the basic unit.

The “trend” in “grasp the general trend” mentioned in the study of the Politburo of the Central Committee is that the foundation of the entire information technology in the world is changing, and it is entering a new computing architecture and At the demarcation point of basic capability breakthrough, a new system needs to be rebuilt in advance. The construction of the system involves basic theory, basic materials, basic technology and device equipment, and forms the wide application of quantum technology, which will eventually change the entire digital technology. Once a country masters this technology, it will make a big breakthrough in computing power and have a revolutionary impact on social development. At this point, the starting point at home and abroad is basically the same, and the world has entered the “no man’s land” together. It is precisely because of this that quantum technology is also a strategic battleground for all countries.

It can be seen that under the current situation, the development of quantum technology has great strategic significance.

Quantum technology is still dominated by enterprises in the world, and is developed in the form of production, education and research. The more typical companies in the world are IBM, Google, and Google built the first quantum computer in 2019, which only takes 200 seconds to complete a calculation, while it takes about 10,000 years to adopt a traditional computer.

China is keeping pace with European and American countries in the research of quantum technology, at least not in a backward position. It should be seen that this technology has achieved certain breakthroughs in the world, but it is not in a mature development stage, so China still has a great opportunity to lead and dominate this competition. In China, quantum technology is still dominated by enterprises, and the world’s first quantum science experimental satellite from China””Mozi”, China’s first quantum secure communication backbone network, is the result of enterprise-based, industry-university-research cooperation. Part of the project leader, Guodun Quantum Enterprise, was incubated by the Chinese Academy of Sciences. Tencent established a quantum computing experiment specially In addition to focusing on applications in information processing, such as the help of quantum algorithms for machine learning, it is also actively exploring more classical computing or simulation methods for some small systems and small molecules, and has applications in pharmaceutical, material, chemical and other industries.

In the final analysis, quantum technology has two essential meanings, one is to improve the security of information communication; the other is to improve computing power. At present, quantum computing can be widely used in many industries Field.

Quantum technology is an important force in the digital technology system. Looking at the learning points proposed by the Political Bureau of the Central Committee of the Communist Party of China, whether it is quantum technology, or big data, artificial intelligence, and blockchain, all are The core content of digital technology is the core force to promote the era of digital economy.

Digital technology is to use the data of the physical world to construct a digital world that forms a mapping relationship with the physical world, and uses computing power and algorithms Science and technology to produce useful information and knowledge to guide and optimize economic and social operations in the physical world.

Digital technology is an iterative upgrade of a new generation of information technology. With the continuous advancement of digitalization, The connotation of “new generation information technology” has been greatly broadened. New technologies such as cloud computing, big data, mobile Internet, Internet of Things, artificial intelligence, and blockchain are emerging one after another. Technology fields such as quantum computing and brain-computer interface have broken through traditional information technology fields. It will be possible to change the entire information computing system.

Judging from the digital technology innovation practices of major countries and leading enterprises in the world, digital technology has gradually become a new innovation and competition hotspot in various countries. On the one hand, major digital technology giants focus on digital technology and digital technology, such as Google’s AI, quantum computing, knowledge automation engine technology; Microsoft and Amazon’s cloud computing and AI; Dassault, PTC, Siemens, ESI and other companies’ digital Twin breakthrough; Apple’s closed digital technology ecosystem based on processor innovation.

On the other hand, the innovation of digital technology giants is inseparable from data science and technology digitization, such as Google Waymo driverless, which requires continuous Continuously integrate digital technology with related disciplines, technologies and industries of automobiles to realize the realization of value from data to domain knowledge.

From the perspective of economic development, digital technology transforms workers from human to human It has become “human + machine”, and laborers can show exponential growth; the means of production have become “industrial and agricultural supplies + data”, and the data has changed from tangible to intangible, and there is no limit to the quantity; the labor materials have become “industrial and agricultural equipment”. + Computing power-driven digital technology equipment”, showing exponential growth, unprecedented liberation of productivity, and rapid entry of human society into the digital age. It can be said that digital technology points to the digital economy in the near term, and in the long run See Point to Knowledge Civilization.

From the perspective of promoting innovation, digital technology drives the network collaborative innovation model. In the industrial age, the innovation process is a one-way linear process from basic research to applied research to industrial development “chain innovation”. Digital technology requires the interaction and integration of the physical world and the digital world. On the one hand, it needs to solve practical applications, meet user needs, and develop scenario-based R&D and innovation to develop new markets. Starting from user needs, it will form a reverse traction for scientific research. Seek breakthroughs in basic and applied innovations in basic disciplines and basic technologies. Each innovation subject is one of the nodes in the huge network system, and will participate in the whole process of development and application of new science, technology and new products, and the cycle of innovation and industrialization is greatly shortened.

Therefore, under the influence of changes in production factors and innovation models, digital technology will eventually reshape the global economic competition pattern. In the early stage of the development of the digital economy, digitization caused the service industry to enter more complex traditional fields such as industry, energy, and transportation. However, with the development of digital technology, more changes are made through data processing, simulation modeling, and machine learning. From the whole process of data-information-knowledge, and push it into the stage of knowledge automation, so that data can enter the system of value creation. This kind of power determines that digital technology will reshape the global economy and industrial structure, and it must also be the strategic commanding height of competition between major powers and enterprises.

⑥ What is the difference and connection between blockchain and bitcoin
/h2>

Blockchain technology is a new technology derived from the development of the bitcoin economy. The blockchain technology can effectively serve the bitcoin economy, and they are interrelated. Bitcoin isA kind of virtual currency only circulates in a specific network economic environment. Blockchain technology can not only be applied to the economy, but also can be used in all walks of life at present. This is their difference.

Blockchain technology

Because blockchain technology is still an emerging product, there is no accurate or definite definition and concept. Simply put, blockchain technology is a mode of encrypting and managing data, which can protect data to a large extent. Blockchain technology has the remarkable features of decentralization, openness, independence, security and anonymity. Its characteristics are well adapted to the requirements of information protection and information disclosure in all walks of life today. On the one hand, it ensures the security of data and avoids the interference of data processing by factors such as human subjective emotions and system failures. On the other hand, it is up to the data individuals to decide whether to hide their details from the group for the purpose of protecting privacy.

At the same time, there is no doubt that blockchain technology is still in a state of preliminary development. The society does not have a deep enough understanding of it, and scholars are still in the stage of continuous exploration. Through the correct application, blockchain technology will bring many positive impacts to society.

⑦ I want to know the difference between blockchain technology and artificial intelligence. It seems that they both claim to be the next era. Who is more important?

Both blockchain and artificial intelligence are is the next era.

There can be a good combination between the two.

Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain (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. The data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

Artificial Intelligence, the English abbreviation is AI. It is a new technical science that studies and develops theories, methods, techniques and application systems for simulating, extending and expanding human intelligence.

Artificial intelligence is a branch of computer science that attempts to understand the nature of intelligence and to produce a new type of intelligent machine that responds in a manner similar to human intelligence. Research in this area includes robotics , language recognition, image recognition, natural language processing and expert systems. Since the birth of artificial intelligence, the theory and technology have become more and more mature, and the application field has also continued to expand. It is conceivable that the technological products brought by artificial intelligence in the future will be the “container” of human intelligence. Artificial intelligence can simulate the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can think like human beings and may surpass human intelligence.

Blockchain technology can be divided into three versions at this stage.

At present, in the first three versions, there are problems that cannot truly achieve decentralization, low scalability, incentives for block producers and the best income for the entire network. Mismatch, the network always runs at maximum capacity, like Bitcoin and Ethereum, affects efficiency.

Velas combines the two to develop a public chain that can learn and progress by itself.

Velas enhances its consensus algorithm through artificial intelligence (AI)-optimized neural networks, self-learning and self-optimizing public chains, and is committed to improving the security, interoperability, and highly scalable. Velas adopts AI-enhanced DPoS consensus to achieve complete decentralization without compromising security and transaction speed.

Technically, Velas has integrated cross-chain payment, multi-currency multi-signature wallet, anonymous transfer and other functions and services. Its ecosystem focuses on exchanges, multi-signature wallets, Merchant platforms and other application scenarios covering transactions and payments, and after AI is fully integrated into the system, transfer fees can be completely exempted in the end.

And, fully decentralised through AI-enhanced DPoS (AIDPoS)>AI chooses who stakes tokens according to the needs of the blockchain>Velas only produces blocks when needed > Scalability (scalable to 30,000 TPS) > Block producers are selected by human intuition.

⑧ What is the difference between blockchain and bitcoin

‍‍‍‍

There are many friends around who mention blockchain and think it is bitcoin. This is actually biased. Just like: When it comes to wood, think of it as a table.

In fact, Bitcoin and blockchain are not the same thing at all, and blockchain is just the core implementation technology behind Bitcoin. Blockchain can be applied not only to Bitcoin, but also to electronic bills, equity registration, luxury goods tracking anti-counterfeiting and other fields.

Bitcoin, as a system with no core institutional management and distributed autonomous operation, has successfully realized the global payment and The circulation function fully reflects the unique advantages of blockchain technology.

In general, Bitcoin is a successful application of the blockchain, and it is also the first stable blockchain.

In the future, with the continuous deepening of blockchain research and the continuous promotion of social capital, as a basic application technology, blockchain will definitely play a more important role in various industries of the society.

⑨ The difference between blockchain technology and tcp/upd

TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) protocols are transport layer protocols. Among them, TCP provides reliable data transmission in the IP environment. The services it provides include data streaming, reliability, effective flow control, full-duplex operation and multiplexing. Sent via connection-oriented, end-to-end and reliable packets. In layman’s terms, it opens up a connected channel for the data to be sent in advance, and then sends the data; while UDP does not provide reliability, flow control or error recovery for IP.
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that realizes the establishment of trust between different nodes and the acquisition of rights and interests in the blockchain system. The blockchain is equivalent to the Internet in the 1990s, and digital currencies such as bitcoin and common silver are all applications of the blockchain.
