㈠ What does blockchain mean?

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. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of The information of Bitcoin network transactions is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

Blockchain is closely related to people’s production and life in public management, energy, hotel management, transportation and other fields, but the centralized nature of these fields also brings some problems , can be transformed using blockchain.

The decentralized fully distributed DNS service can realize domain name query and resolution through point-to-point data transmission services between each other in the network, and can be used for the operating systems and firmware of some important infrastructures. If it has not been tampered with, the status and initialization of the software can be monitored to detect bad tampering and ensure that the data transmitted by the system using IoT technology has not been tampered with.

㈡ What is blockchain technology? What is blockchain? A chained data structure composed of sequential connections, and 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 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.

[Infrastructure]

Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer composition. Among them, the data layer encapsulates the underlying data blocks and related basic data and 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.

Extended information:

[Blockchain core technology]

Blockchain mainly solves the trust and security issues of transactions, soIt proposes four technological innovations to address this problem:

1. Distributed ledger, which means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete record Accounts, so they can all participate in supervising the legality of transactions and can also jointly testify for them.

The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally stores The data is divided into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and of equal status, relying on the consensus mechanism to ensure storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through the central node.

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, unless all nodes are destroyed, the accounts will not be lost, thus 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.

4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. 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 automate claims settlement in some standardized insurance products.

In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.

㈢ What is blockchain and how can you make money from it

Blockchain is actually dataSharing Center. But this data sharing center has limitations.

Blockchain is a term in the field of information technology. As mentioned earlier, the blockchain is a data sharing center. This data sharing center is different from other data sharing centers in that it has certain characteristics. These characteristics include "unforgeable", "leaving traces throughout the entire process", "traceable", "open and transparent", "collective maintenance", etc.

Blockchain itself cannot make money. But we can use blockchain to implement technical services and applications. Earn revenue through technical services and application implementation. In this process, the blockchain is only equivalent to providing a medium and a bridge between those who provide technical services and those who purchase services. Blockchain provides relevant data so that buyers and sellers can reach consensus.

㈣ What is blockchain and why it is the future development trend

Blockchain is a public database (or public ledger) based on blockchain technology.

Blockchain can add a layer of accountability and security to IoT data and become a future enabler of IoT efficiency, scalability and standardization. It can also serve as an enabler for IoT applications such as supply chain tracking and tracing. For example, in healthcare, blockchain-enabled IoT devices will allow patients to control access to the data collected by these devices.

The technology will make devices more resistant to cyberattacks and provide a detailed record of when another party accessed data. In supply chains, blockchain-based systems, powered by smart contracts, can automate payments based on specific conditions measured by IoT sensors.

Blockchain knowledge points

The main advantages of blockchain technology in the financial field are disintermediation and great cost reduction. First of all, the financial industry Currently, to prevent single points of failure and systemic risks, layers of audits are required to control financial risks, but this also results in high internal costs.

And due to the increasing number of regulatory regulations, especially the 2008 financial crisis, the threshold for financial control has continued to rise, and the war on terrorism has led to the scope of anti-money laundering and counter-terrorism financing, which has also limited the breadth and scope of supervision. The depth gradually expanded, leading to a sharp increase in regulatory costs for the entire financial system.

Is Pi Coin a scam?

Pi Coin is an online platform for mining digital currencies.

Of course it is not a scam.

< p>It accepts real-name registration in more than 170 countries around the world.

It is not illegal software.

It is just that some areas will prompt the risks of financial management

Currently It is in the second phase of the test network.

[Extended reference materials]:

Pi(π)Network's APP is a mobile mining (Shiguang) software, used to mine Pi (π) coins. In the past, currency mining that used the proof-of-work mechanism such as Butte B required computing resources, and you had to spend money to buy a machine to participate, and small businesses could only stand aside.

The advantage of current Pi(π) coin mining (Shi Guang) is that everyone can participate, creating a truly global digital currency network, and there is no need to waste mobile phone data or data during mining (Shi Guang). power, you can dig (Shi Guang) even when the APP is closed, you only need to turn on the dig (Shi Guang) switch once a day.

Why is the number of users growing so fast?

First of all, Pi is a free mining (Shi Guang) project. It does not require investment of funds and resources. It only needs to be opened once a day. The simple gameplay can attract many original coin circle users;

Secondly,

The recent news of Facebook’s currency issuance has made many users outside the currency circle (especially overseas Facebook users) begin to understand blockchain and digital currency. Pi was launched at the right time. It also supports direct login to Pi using Facebook accounts and mainland Chinese mobile phone numbers, allowing these eager potential users to find a way to really start trying digital currency.

Why are there so few domestic players?

First of all,

Domestic users cannot use Facebook, Twitter and other foreign social software. The Pi project party has relatively little publicity, and domestic users can see even less. ;

Secondly,

the entire project is not optimized enough for domestic users, and the difficulty in downloading and the English interface have dissuaded many domestic players; in addition, various domestic players currently use block There are many funds and model coins made in the name of the chain. New users are often more interested in such simple and crude things that can make money quickly. Projects like Pi that do not tout profits will be ignored.

㈥ What does blockchain mean and how to understand it?

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. As the underlying technology of Bitcoin, it is a series of related data generated using cryptography methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

Notes

1. Blockchain Originated from Bitcoin, on November 1, 2008, a person calling himself Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", explainingThe architectural concept of an electronic cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., marks the birth of Bitcoin.

Two months later, the theory came into practice, and on January 3, 2009, the first genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.

2. In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China’s economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that generations have been striving for, Puyin Group launched the On the 9th, a Puyin Blockchain Finance Guiyang Strategy Release Ceremony was held in Guizhou. At the meeting, the digital circulation of assets through blockchain, the blockchain financial transaction model, and the application of blockchain services and social public industries will be discussed. Explore.

㈦ What does this public blockchain mean in simple terms and what is its use?

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. In recent years, more and more people regard blockchain technology as one of the most promising new technologies in the future. Right now, there is a lot of talk about how cryptocurrencies and blockchain will change the world economy. Although the future of cryptocurrencies is unpredictable, the unshakable status of blockchain may continue to lead the development of the industry in the future. In fact, blockchain has changed not only the world economy, but even the daily lives of ordinary people have been greatly changed by its impact. The emergence of blockchain technology itself is an innovative process. Anyone who understands blockchain technology should know that blockchain is a database that can collaborate on a large scale. It allows many different subjects to collaborate to complete a task without trusting each other. This is the essence of blockchain.

Since this year, there have been numerous cases about blockchain technology supporting the resumption of work and production of small and medium-sized enterprises.

(8) Extended reading of blockchain publicity knowledge pictures:

Blockchain is far more than just a technology, it involves The spirit of "multi-party collaboration". In modern society, many things must rely on everyone's cooperation to achieve the effect of 1+1>2, but in cooperation, we need to try our best to avoid problems such as "information asymmetry."

Therefore, alliance members jointly keep accounts, share data, and make everything public to eliminate "information asymmetry" to protect everyone's interests and allow the business environment to develop healthily. do things honestlyYou will get the benefits you deserve, and if you cheat, it will naturally be known to everyone and criticized by thousands of people. Technology is the foundation that helps realize this model. This is the more important "blockchain thinking".
