❶ Blockchain technology concept
Blockchain technology concept
Blockchain technology concept, nowadays, blockchain has become most It is an area that people are paying attention to. Many companies have already studied this technology in depth, but there are still people who don’t know much about it. Below I will share an article about the concept of blockchain technology.
Blockchain technology concept 1Basic concepts and working principles of blockchain
1. Basic concepts
Blockchain is a distributed data storage, point-to-point New application models of computer technologies such as transmission, consensus mechanisms, and encryption algorithms. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity of the information, prevent counterfeiting, and generate the next block.
In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.
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 data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.
2. Working principle
The blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.
Blockchain mainly solves the trust and security issues of transactions, so it proposes four technological innovations to address this issue:
1. Distributed ledger, that is, transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they can all participate in supervising the legality of the transaction and can also jointly testify for it.
Different from traditional distributed storage, the uniqueness of blockchain distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. For data, traditional distributed storage generally divides the data into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and has equal status, relying on the consensus mechanism to ensure the consistency of storage, while traditional distributed storage generally synchronizes data to other backup nodes through the central node. [8]
No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.
2. Asymmetric encryption and authorization technology. Transaction information stored on the blockchain is public, but account identity information is highly encrypted and can only be accessed with authorization from the data owner. , thus ensuring data security and personal privacy.
3. The consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.
The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be the computing power and the number of shares. Or other characteristic quantities that the computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result. Taking Bitcoin as an example, it uses proof of work. Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. When there are enough nodes joining the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data. Some predefined rules and terms can be automatically executed. Take insurance as an example. If everyone's information, including medical information and risk occurrence information, is true and trustworthy, it will be easy to implement automated claims settlement in some standardized insurance products.
3. Others
The Internet exchanges information, and the blockchain exchanges value. Human history and the history of the Internet can be understood in eight words: if they are separated for a long time, they will be reunited. When they are separated for a long time, they will be reunited.All information is scattered on the Internet, and it is very difficult for everyone to mine information. At this time, platforms such as Google and Facebook will appear. The only thing they do is to reorganize all our information. In the Internet era, what the monopoly giants reorganize is information, rather than generating their own information. The information generated is entirely our own. Once the information is reorganized, a new monopoly giant will emerge, so it will be an era of long-lasting separation. Now, due to the emergence of blockchain technology, it has entered an era of integration and division. It is a new multi-centralization. After the new multi-centralization, new value will be generated. These data will be in our own hands, and personal data will generate value. It belongs to oneself. This is the most exciting era of this era.
What is the value of blockchain? A low-cost mechanism to establish trust, establish data rights, and resolve data property rights.
At present, blockchain technology continues to develop, including the current development of single chains to multi-chains, and the technology can be further expanded. I think there may still be disruptions in the future, especially in transactions and other aspects. , especially many disruptive scenarios for existing industries.
The essence of blockchain is to establish trusted information exchange on untrustworthy networks.
One Belt, One Road + One Chain. The bigger thing about blockchain is not to create trust, but to allow trust to be transmitted losslessly, reducing the friction cost of society as a whole, thereby improving the overall efficiency.
Now the blockchain itself is still in its initial stage, so it includes the information transmission and encryption of the blockchain. Quantum encryption and other encryption appear in this process, which actually attacks the encryption algorithm used by the blockchain itself. This phenomenon also occurs from time to time. Including blockchain is also a recognition of assets, a recognition of digital assets, but now many of us use cryptographic algorithms, or as the key for us to decrypt, but if you forget the password, it is very likely that your current assets will be lost. If you lose them, you won't be able to get back your original assets. Therefore, there are still some hidden dangers in asset management, including information transmission and some security aspects. Of course, from a technical perspective, the processing speed of our blockchain itself, or its scalability, is because from the perspective of the working mechanism, the entire ledger must be copied to all participants, so in the blockchain Its operational efficiency and scalability are still relatively limited. We feel that these still need further development in terms of technology.
The underlying technologies of the blockchain platform also form blockchain wallets, blockchain browsers, node elections, mining machines, mining pools, development components, development modules, technical communities and project communities. and a series of ecosystems. The perfection of these ecosystems directly determines the efficiency and effectiveness of the underlying platform of the blockchain.
4. Mundell’s Impossible Triangle
It is impossible to achieve the ultimate in decentralization, efficiency, and security at the same time.
Blockchain Technology Concept 2BlockchainIt is essentially a distributed accounting technology, as opposed to a centralized accounting technology, which is widely used in our current lives. 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 related cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity and anti-counterfeiting of the information and generate the next block.
In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.
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 data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.
The popular understanding of blockchain technology is: connecting the front, back, left and right blocks of "things" into a chain using one technology, but each block The original data of the block cannot be tampered with. It is a "linked module" technology in the field of Internet of Things that allows participants to trust. The application of blockchain technology is inseparable from the Internet and the Internet of Things. It is based on the integration and interaction of the two, but allows participants to remain independent, decentralized, and work together. With this set of value chain co-construction and sharing, technology.
Characteristics of blockchain: decentralization, openness, autonomy, information cannot be tampered with, and anonymity.
Blockchain is a network that can deliver value. The demand for a network that can deliver value is an important reason for the emergence of blockchain technology. Blockchain emerged driven by the need to protect information with ownership or other value. Through public and private key cryptography, distributed storage and other technical means, the blockchain ensures on the one hand the efficient transmission of valuable information, and on the other hand ensures that this information will not be easily copied and tampered with during the transmission process.
Understand the connotation of blockchain from the inevitability of its birth. Blockchain is a distributed accounting technology that solves the shortcomings of centralized accounting and solves the problem of distributed consistency. It is also The connected Internet is upgraded to a value network that ensures the safe and efficient transmission of valuable information.
Blockchain Technology Concept 3Blockchain: Blockchain is like a globally unique account book, or database, which records the history of all transactions in the network.
Ethereum Virtual Machine (EVM): It allows you to write more powerfulScript programs and programs can also be written on Bitcoin. It is also sometimes used to refer to the Ethereum blockchain, which is responsible for executing smart contracts and everything.
Node: You can run a node to read and write to the Ethereum blockchain, that is, using the Ethereum Virtual Machine. Full nodes require downloading the entire blockchain. Light nodes are still under development.
Miner: Mining, that is, the node that processes blocks on the blockchain. You can see some of the currently active Ethereum miners on this page: stats.ethdev.com.
Proof of Work: Miners are always competing to solve some mathematical problem. The first one to solve the problem (calculate the next block) will be rewarded with Ether coins. All nodes then update their own blockchain. All miners who want to figure out the next block have an incentive to stay in sync with other nodes and maintain the same blockchain, so the entire network can always reach consensus. (Note: Ethereum is planning to move to a proof-of-stake system (POS) without miners, but that is beyond the scope of this article.)
Ethereum: Abbreviation ETH. A true digital currency that you can buy and use. Here is a chart from one of the exchanges where Ethereum can be traded. At the time of writing, 1 Ether is worth 65 cents.
Gas: Executing programs and saving data on Ethereum consumes a certain amount of Ethereum. Gas is converted from Ethereum. This mechanism is used to ensure efficiency.
DApp: The Ethereum community calls applications based on smart contracts decentralized applications (Decentralized App). The goal of DApp is (or should be) to have a friendly interface for your smart contracts, plus some extras, such as IPFS, a decentralized network that can store and read data, not from the Ethereum team but in a similar spirit ). DApp can run on a centralized server that can interact with Ethereum nodes, or it can run on any Ethereum equal node. (Take a minute to think about this: Unlike ordinary websites, DApps cannot run on ordinary servers. They need to submit transactions to the blockchain and read important data from the blockchain rather than a centralized database. Compared to typical users When logging into the system, the user may be represented as a wallet address and other user data is stored locally. Many things will be structured differently from current web applications.)
Ethereum client, smart contract language
p>Writing and deploying smart contracts does not require you to run an Ethereum node. Browser-based IDEs and APIs are listed below. But if you are just learning, you should still run an Ethereum node to understand the basic components, and running a node is not difficult.
Clients available for running Ethereum nodes
Ethereum has many clients in different languages.Client implementation is a variety of methods for interacting with the Ethereum network, including C++, Go, Python, Java, Haskell, etc. Why do we need so many implementations? Different implementations can meet different needs. For example, the goal of Haskell implementation is to be mathematically verifiable, to make Ethereum more secure, and to enrich the entire ecosystem.
At the time of writing this article, I am using the client geth (go-ethereum) implemented in the Go language. At other times, I also use a tool called testrpc, which uses the Python client pyethereum. Later examples will use these tools.
About mining: Mining is fun, a bit like caring for your houseplant, but also a way to learn about the entire system. Although the current price of Ethereum may not even cover the electricity bill, who knows in the future. People are creating many cool DApps that may make Ethereum more and more popular.
Interactive console: Once the client is running, you can synchronize the blockchain, create a wallet, and send and receive Ethereum. One way to use geth is through the Javascript console. In addition, you can use cURL-like commands to interact with the client through JSON RPC. The goal of this article is to take you through the process of DApp development, so I won’t go into details about this. But we should remember that these command line tools are useful for debugging, configuring nodes, and using wallets.
Running the node on the test network: If you run the geth client on the official network, it will take quite a while to download the entire blockchain and synchronize with the network. You can determine if synchronization has occurred by comparing the last block number printed in the node logs with the latest block listed on stats.ethdev.com. ) Another problem is that running smart contracts on the official network requires real Ethereum. Running the node on the test network does not have this problem. At this time, there is no need to synchronize the entire blockchain. Just create your own private chain, which saves time for development.
Testrpc: Use geth to create a test network. Another faster way to create a test network is to use testrpc. Testrpc can help you create a bunch of test accounts with funds at startup. It also runs faster and is therefore better suited for development and testing. You can start with testrpc, and then as the contract slowly takes shape, move to the test network created by geth - the startup method is very simple, you only need to specify a networkid: geth --networkid "12345". Here is the code repository for testrpc, we will talk about it again below.
Next, let’s talk about the available programming languages, and then we can start the real programming. The programming language used to write smart contracts is SoJust lidity.
There are several languages to choose from for writing smart contracts: Solidity, which is somewhat similar to Javascript, has a file extension of .sol. Serpent, which is similar to Python, has a file name ending in .se. There is also a Lisp-like LLL. Serpent has been popular for a while, but now the most popular and stable one is Solidity, so just use Solidity. I heard you like Python? Use Solidity.
solc compiler: After writing the smart contract with Solidity, you need to use solc to compile it. It is a component from a C++ client implementation. Again, different implementations complement each other. Here is how to install it. If you don't want to install solc, you can also use a browser-based compiler, such as Solidity real-time compiler or Cosmo. The programming sections below will assume you have solc installed.
web3.js API. After the Solidity contract is compiled and sent to the network, you can use Ethereum's web3.js JavaScript API to call it and build web applications that can interact with it.
❷ What is the relationship between blockchain and artificial intelligence?
Blockchain and artificial intelligence have many potential correlations and interactions. They can promote each other and make up for defects, thus Make progress together.
On the one hand, at the application level, artificial intelligence technology Liang Suichen can provide the blockchain platform with more complete data processing and analysis capabilities. For example, artificial intelligence technology can help blockchain platforms conduct large-scale data mining and analysis, discover hidden correlation patterns and trends, and improve data processing efficiency and security. At the same time, blockchain technology can also provide a more accurate, real-time, and credible data source for artificial intelligence algorithms by establishing a decentralized, non-tamperable data storage and transmission mechanism, further improving its decision-making and prediction capabilities.
On the other hand, at the technical research level, blockchain technology and artificial intelligence technology also have the possibility of integrating with each other and accelerating development. For example, some researchers apply blockchain technology to decentralized artificial intelligence training and data collaboration processes to solve issues such as privacy protection and data traceability in the current artificial intelligence field; some researchers are also exploring How to use artificial intelligence algorithms to optimize and accelerate the blockchain transaction confirmation and on-chain data verification process, and further improve the development efficiency and security of blockchain technology.
In short, in the field of cross-application of blockchain and artificial intelligence, they can promote and support each other, and produce more complex and diversified technological innovation combinations, which can contribute to the development of the digital economy and enterprises. Have a positive impact.
❸ I want to understand the difference between blockchain technology and artificial intelligence. It seems that they are claiming to be the next era. Which one is more important and awesome?
Both blockchain and artificial intelligence It's the next era.
There can be a good combination between the two.
Blockchain is a new application model of computer technologies 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. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each The data block contains information about a batch of Bitcoin network transactions and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
Artificial Intelligence (Artificial Intelligence), the English abbreviation is AI. It is a new technical science that studies and develops theories, methods, technologies 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 produce a new intelligent machine that can respond in a manner similar to human intelligence. Research in this field includes robotics , language recognition, image recognition, natural language processing and expert systems, etc. Since the birth of artificial intelligence, the theory and technology have become increasingly mature, and the application fields have also continued to expand. It can be imagined that the technological products brought by artificial intelligence in the future will be the "containers" of human wisdom. Artificial intelligence can simulate the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can think like humans and may even exceed human intelligence.
Blockchain technology can currently be divided into three versions.
At present, in the first three versions, there are problems such as the inability to truly achieve decentralization, low scalability, incentives for block producers and the best benefits for the entire network. Mismatch, the network always runs at maximum capacity, such as Bitcoin and Ethereum, affecting 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 security of the transfer process and smart contracts. and highly scalable. Velas uses AI-enhanced DPoS consensus to achieve complete decentralization without reducing security and transaction speed.
Technically, Velas has integrated cross-chain payments, multi-signature wallets that support multiple currencies, anonymous transfers and other functions and services. Its ecosystem focuses on exchanges, multi-signature wallets, All application scenarios covering transactions and payments such as merchant platforms, and after AI is fully integrated into the system, transfer fees can eventually be completely eliminated.
And, fully decentralized through AI-enhanced DPoS (AIDPoS) >AI chooses who to stake tokens based on the needs of the blockchain >Velas only produces blocks when needed < every 1 second to every 2 minutes Time > > Scalability (scalable to 30,000 TPS) > Block producers are selected through human intuition.
❹ What is the Internet of Things, what is big data, what is blockchain
1. What is the Internet of Things
In fact, to put it simply, big data assists decision-making by analyzing and mining a full amount of non-sampled data.
Characteristics of big data
Big data refers to massive and high-volume data that are intended to serve the purpose of decision-making and require new data processing models to collect, store, manage and analyze their content. Growth rates and diverse information capital.
Big data has the following essential characteristics:
1. The fundamental purpose is to serve decision-making. Big data can help various organizations and individuals greatly improve their decision-making capabilities and make better decisions. Decision-making and judgment;
2. Large scale, big data usually refers to the amount of data above 100T, which is difficult to rely on traditional computing methods to effectively calculate, but must rely on new computing methods and data mining tools;< /p>
3. High frequency. Big data is data generated by user participation and interaction. It is used to understand user-related data in a timely manner based on the user’s network traces. This kind of data is high-frequency based on days or even hours. data. The frequency of traditional data is very low, and a lot of data is calculated by month or even year;
4. Fast, big data is real-time data and can respond in real time. For example, entering a keyword in the Internet search box can be displayed instantly, while traditional data collection methods are seriously lagging behind;
5. Always online. Online is a prerequisite for big data. From this perspective, big data is always online and can be called at any time. By analyzing user traces on various network terminals, big data can better analyze users' behaviors, emotions, thoughts, hobbies and needs for better decision-making and analysis.
Three key points of big data
First, the availability of data. At present, the development of big data in China is seriously restricted by the lack of openness of government information. Many data are difficult to obtain, making it difficult to realize real big data mining and analysis. This requires the government to open more data in a timely manner to improve the reliability of the data. Gain degrees.
Secondly, carry out scientific model construction. The scientific nature of the model directly determines the quality of data analysis, which requires a high level of modeling. Of course, a larger amount of data will also help in the reasonable construction of the model.
Third, use experts to refine opinions. Unique, high-quality insights based on data mining to inform decision-making, highly dependent onFor high-quality data interpretation, this reflects the value of industry experts.

❺ The relationship between artificial intelligence and blockchain
The common points between artificial intelligence and blockchain
Blockchain The focus is on maintaining accurate records, authentication and enforcement, while AI facilitates decision-making, evaluation and understanding of certain patterns and data sets, ultimately resulting in autonomous interactions. Artificial intelligence and blockchain share several features that will ensure seamless interactions in the near future. Three main features are listed below.
1. Artificial intelligence and blockchain require data sharing
Distributed databases emphasize the importance of sharing data among multiple clients on a specific network. Likewise, artificial intelligence relies on big data, especially data sharing. The more open data available for analysis, the more accurate the machine’s predictions and assessments will be, and the more reliable the algorithms generated will be.
2. Security
When dealing with high-value transactions on a blockchain network, this places great demands on the security of the network. This can be implemented through existing protocols. For artificial intelligence, machine autonomy also requires high levels of safety to reduce the likelihood of catastrophic events.
3. Trust is a must
There is no greater threat to the advancement of any widely accepted technology than a lack of trust, and artificial intelligence and blockchain are not excluded. In order to make communication between machines more convenient, there needs to be an expected level of trust. To perform certain transactions on a blockchain network, trust is a necessary condition.
The impact of blockchain and artificial intelligence on ordinary people
Simply put, blockchain is a community-based technology that can make value exchange safer. Blockchain is like its Same name. It is an ever-extending chain of many data blocks connected together. Each block contains an encrypted transaction record. The blocks are arranged in chronological order and protected by a cryptographic system. Blockchain is a technology that can change the rules, and its emergence is a revolutionary innovation.
Blockchain also has many functions, and its specific applications are also very wide. For example: if blockchain is used in the food industry, people will no longer worry about eating harmful food. If blockchain is used in diamond production, consumers no longer have to worry about buying fake diamonds. If blockchain is used in the education industry, intellectual property protection can be strengthened. If blockchain is used in the insurance industry, it can alleviate information asymmetry in the insurance business and help improve the security of the insurance business, etc.
Blockchain and artificial intelligence have a huge impact on ordinary people. Just imagine, if blockchain and artificial intelligence are combined, will their role be expanded? Yes, the combination of the two can indeed have more impact to change the lives of ordinary people.
Blockchain and artificial intelligence are two extremely important roles in the technology field, each bringing convenience to our production and life. If we find a smart way to make themWorking together, the impact of their interaction is unimaginable. This is also the core of OMT. After the two technologies are combined, future application scenarios will be revolutionary and exciting. In the new ecological construction, data storage, sharing mechanisms, platform issues, security issues, etc. can all be Leverage each other's technologies to overcome difficulties. OMT will create maximum value for global users and enterprises through blockchain + artificial intelligence technology, and bring more convenience to ordinary people.
The answer is complete and I hope you will adopt it, thank you!
❻ Talking about technological changes - the evolution of artificial intelligence, the Internet of Things, and blockchain
I have read a lot about it recently According to reports on blockchain, I feel that the popularity of blockchain has many similarities with the popularity of artificial intelligence and the Internet of Things. The following are some personal opinions:
1. The emergence of artificial intelligence, the Internet of Things, and blockchain are all human exploration of the future.
Human beings are a very peculiar group. There is always a group of people who will find an exit in our era, so that we can feel that society is functioning normally. Because of the explosion of technology, people's desire for innovation is unprecedented. Regardless of the outcome, the starting point of these desires is always good.
On the one hand, the popularity of artificial intelligence is due to the development of these three aspects, which we often call deep learning, big data, and computing power; on the other hand, the Internet has been developing for decades and requires new technologies. Things emerge to take over the consequences of the development of the Internet, such as big data and some inefficient Internet mechanisms. The Internet has been developing for so many years, and during this period we can also see some new things being invented or mentioned, such as the Internet of Things. However, it gradually faded over time. At the beginning, when the Internet of Things appeared, many people thought that the Internet of Things was the next exit for mankind after the Internet. Later, many problems emerged, such as limitations in data processing capabilities and limitations in sensor intelligence, and the Internet of Things was gradually marginalized. Then came the emergence of solutions to problems in the development of the Internet of Things - artificial intelligence.
Overall, the development of these technologies has either been truly successful, or it has led to some new problems, and the solutions to these new problems have formed new technologies. This reminds me of what Mr. Wang Qiang of ZhenFund said: It is the questions, not the answers, that change the world.
After so many years of development of human society, there is always a problem that needs to be solved, and that is decentralization. It is worth explaining that the blockchain is not completely decentralized, but only an improvement in efficiency, which also has costs. Many media reports today are misleading in themselves.
2. Who is the next exit between blockchain and the Internet of Things?
The author believes that the Internet of Things is the next exit for mankind. compared toAs far as blockchain is concerned, the Internet of Things is more likely to become a new outlet, because the previous wave gave it certain advantages in policy, and compared to the Internet, the Internet of Things is a downplayed central network. Here is an explanation of what a decentralized network is. The Internet is a platform-centric network. Communication between people must be concentrated on a platform. This platform is what we often call a trust mechanism. The Internet of Things is a decentralized network. Sensor devices self-organize into a network. This network node is no longer an enterprise or a platform. In other words, the platform distributes and optimizes centralized rights, making each node possible to become the center.
As for the blockchain, the decentralization that its core technology demands is still too urgent. However, in some fields, this kind of decentralization demand is still welcome, such as finance, house leasing and other business needs that are suitable for the p2p model. The author believes that the biggest reason why the next exit is the Internet of Things is that compared to the blockchain, the decentralization of the Internet of Things is softer.
3. Artificial intelligence, the Internet of Things, and blockchain will eventually be applied to life.
This sentence may sound a bit nonsense. However, the premise that technology can be applied to life is that the technology itself can solve a series of problems that exist in life. From an economic point of view, all technologies revolve around two words: efficiency. No matter how people view artificial intelligence, the Internet of Things, and blockchain today, one thing is certain: existence is value.
As for the time dimension, we can feel or see that after more than a year of hype, artificial intelligence is gradually being implemented in the industry. Personally, 2018 should be the first year for artificial intelligence to embrace the industry. On the one hand, technology companies and traditional companies are also actively cooperating. On the other hand, new media related to artificial intelligence are also promoting the implementation of artificial intelligence, such as: New Wisdom.
Needless to say about the Internet of Things, the previous government also favored the Internet of Things in policy formulation and related planning. Moreover, in the past few years, commercial applications of the Internet of Things have been developing well. But, it's not as good as I thought before. I believe that with the cooperation of artificial intelligence, the Internet of Things industry will develop rapidly in the future.
For blockchain, it may take a long time to eliminate the bubble. Today’s blockchain bubble is too serious. In addition to market bubbles, blockchain also has to face very severe challenges. Supervision, these issues will take a long time to resolve. Personally, I think it will take longer for blockchain to be implemented in the industry than artificial intelligence. As for many companies today, it is better to concentrate on doing things than to join in the fun. When supervision is unclear, problems are prone to arise in joining the heat.
❼ What is the Internet of Things, what is blockchain, and what is big data
Blockchain has developed to this day and has alreadyIt extends from the initial financial transactions to all applications that require intermediary guarantees or certifications, such as house transactions, car sales, etc., and even through the series connection of APIs, blockchain technology can be integrated with other application services to accelerate the creation of A variety of innovative applications can even help accelerate the development of IoT applications.
The earliest application of blockchain is Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. It is like a database ledger, and the ledger also contains data from Bitcoin. All transaction records since then include multiple block records. Each block corresponds to a part of the transaction and records the hash value of the previous block, forming a chain-like data structure.
Many experts believe that the emergence of blockchain technology solves the missing link in the security, privacy and reliability issues of the Internet of Things. It can be used to track billions of interconnected devices, facilitate transactions and collaborative processing between devices, and save a lot of costs for the IoT industry. This decentralized approach will eliminate single points of failure and create a more reliable of devices running the ecosystem. At the same time, the encryption algorithm used in the blockchain can also bring higher privacy to consumer data.
The advantage of the blockchain is that it is public, and every network participant can see the blocks and the transaction information stored in them. However, this does not mean that everyone can see your actual transaction content, which is protected by your private key.
Blockchain is decentralized. There is therefore no single authority that can approve transactions or set special rules for the receipt of transactions. This means that there is a huge amount of trust between participants, so all network participants must reach a consensus to receive transactions.
The more important point is that the blockchain is very secure. This kind of data can only be continuously expanded, and previous records cannot be changed. And the ledger used by the blockchain is tamper-proof and cannot be manipulated by criminals. This ledger is not located in a specific location and cannot be attacked on middlemen because no single communication thread can be intercepted. .
Blockchain can be applied to the Internet of Things to ensure information security. For example, manufacturers of equipment and instruments can use blockchain technology to trace back the manufacturer, production date, manufacturing batch number and even the manufacturer of each component. Other information about the manufacturing process to ensure the transparency and plasticity of the entire machine production process, effectively improve the availability of the overall system and components, and thereby ensure the safety of the operation of equipment and instruments.
The unique consensus mechanism of the blockchain connects various devices through a point-to-point method, rather than through a central processor. Each device maintains consensus and does not require central verification, thus ensuring When a node has a problem, it will not affect the overall data security of the network.
Now, as blockchain technology continues to develop and heat up, Shenzhen Beihang Internet of Things Research Institute (www.buaaiot.org) believes that it will also use its own unique way, to change and integrate into various industries. The birth of blockchain technology has made various algorithms more efficient. Its decentralized principles and distributed computing rules allow everything to be connected and calculated in seconds, and prevent hackers from attacking data. All kinds of assets can be realized in the area. Registration, transactions and data on the block can never be tampered with or reversed. This intangible charm allows various assets to gather on the block.

What is the difference between the Internet of Things, blockchain, and big data
In the near future, the Internet of Things The number of devices will explode. It may be hundreds of billions or trillions. If such a huge network is still managed in a centralized networking mode, the investment and maintenance of the data center infrastructure should be incalculable. of.
In essence, big data is a small branch of the database, so this problem can be attributed to the relationship with the database. Database is actually a very old research field in software, the Internet world, and the IT world. From the initial file system to the ER model, it later led to the three major achievements of traditional databases that everyone knows: relational model, transaction processing, and query optimization. , until the rise of the NOSql database after the Internet became popular, database technology continued to develop and change, including semi-structured, text, voice and other unstructured data processing represented by XML, etc.
The relationship between blockchain and database actually seems to be such a relationship. From the evolution of database technology, we can find that it always comes from how to meet new business needs. And then create new technologies for processing these data. For example, from the beginning of the file system, why do we need this model of ER? Because of the development of the financial industry, everyone has further needs for these fast accounting, high-concurrency data writing and access, which has led to The emergence and rapid development of the entity relationship model. Why did the NOSql database appear later? It is because the rapid development of the Internet has put forward higher and updated requirements for databases, so essentially we believe that the entire Internet is a large database.
Things are always evolving. Of course, after we solve the massive real-time data processing problems on the Internet through technologies such as NOSql database and cloud storage, the next problem must come, and that is how to solve it in a large-scale manner. Authenticity and validity of data.
For example, it may be related to our diet. From the issue of food and clothing at the beginning, to the issue of nutritional structure, and then to the food safety issue that everyone is concerned about, the development of the database is actually the same. When we pass the ER entity relationship Model, when the problems of data storage and data access can be well solved through the NOSql database, the next thing everyone should be concerned about and solve must be the issues of authenticity and validity.
So at this stage, these technologies represented by blockchain are true, effective and unfalsifiable for data.These requirements of being created and cannot be tampered with are definitely a new starting point and new requirements compared to the current database. We can clearly feel that the integration trend of database and blockchain is actually very close and unstoppable, just like the movie and content production direction just mentioned began to develop in the direction of virtual reality and augmented reality; from the perspective of database , Blockchain is a new way of organizing data. We believe that big data and blockchain are two integrated.
