㈠ What exactly is blockchain and which blockchains have physical applications

What is blockchain?

Official definition: Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission consensus mechanism encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.

Vernacular understanding: A block is to package all the data generated within a time period in chronological order. Generally, the length of a block is 10 minutes, which means that within 10 minutes, all the data on the Internet will The data is packed into a complete package, and this complete data package is called a block. The blockchain links these data packages in order to form a structure, and cryptographically ensures that it cannot be tampered with or forged to form a distribution. ledger, this is the blockchain.

It seems that everyone has a preliminary knowledge and understanding of the blockchain. So whether the blockchain has any practical application in daily life, the answer is yes, the current practical application There are mainly the following aspects. Of course, I may not know some of them. Friends are welcome to leave messages to add.

Financial Industry

Blockchain should be used the most in the financial industry.

For example, in May 2017, OMG (Omise Coin) announced that it would cooperate with Alipay to launch an electronic wallet, integrating the "Alipay" payment solution into its own payment service suite to help local electronics in Thailand. Business merchants accept online payment transactions from Chinese tourists.

Another example is PPT, which is a financial transaction system for bills based on blockchain.

Gaming

The gambling industry entered the blockchain probably last year. Why does gambling favor blockchain? Because blockchain provides a relatively fair betting system. Why? It is relatively fair. As can be seen from the previous introduction, the blockchain cannot be tampered with or forged.

For example, WICC (WikiChain) can realize rich application scenarios such as asset issuance, betting applications, copyright traceability, mutual insurance, decentralized exchanges, and cross-border settlement.

For example, the STX (King of Fighters Token) stox application is designed to provide the full functionality of a prediction market application without the need for any central server. Prediction markets require functions such as event planning, market production, providing information and analysis to traders, reporting event results, and of course collection and payment.

I believe that if the current lottery industry is built on the blockchain, people will become more and more enthusiastic about buying, because there are too many insider tips that make people give up.

Internet of Things

The Internet of Things still has many applications on the blockchain, because the traceability and immediacy of blocks are very suitable for this industry.

For example, DATA is the concept of the Internet of Things. It is a decentralized p2p network. The data source can be connected to any node in the entire networkConnect, then publish the data and the network will send it to subscribers immediately. Horizontal scalability is achieved through sharding pattern. This timeliness and accuracy are very important in IoT applications.

Game industry

For example, GTC (G coin) is a decentralized digital asset based on Ethereum erc20 issued by Game Global. G coin is committed to becoming a universal number in the global game industry. Monetary standards.

For example, MANA is a distributed shared virtual platform. On this platform, users can browse and discover content and interact with other people and entities. Users can also claim ownership of virtual territories through a blockchain-based land ledger. The territory is demarcated by rectangular coordinates (x, y), and its owner can decide the content published on the territory, including static 3D scenes to interactive systems such as games.

There are many other industries. The emperor did not list them one by one, but listed a few representative ones. What is the purpose? It shows that the blockchain is definitely not just a currency transaction, it is a real implementation project, and it is a product of the changes of the times with real practical uses.

The development of human society is actually like the blockchain, it is irreversible and unstoppable. As far as I feel, the blockchain will enter thousands of households sooner or later. Regardless of whether it is bull or bear, hold it in your hands. Value coins and Flush have started quoting digital currencies, which shows that society is accepting it step by step. The power of social development cannot be blocked by any country or person.

㈡ Does the benefit mechanism of blockchain traceability have servers for all transaction parties?

Yes
First of all, blockchain is a multi-party consensus mechanism, and the algorithm of this consensus It is the basis for building trust in the entire technology. It does not rely on trust in people and institutions, but is a relatively democratic mechanism. Under the constraints of this mechanism, the authenticity, validity and continuity of the data are guaranteed, thereby establishing the trust foundation of this alliance business where multiple parties unite and supervise each other.
Secondly, blockchain is also a relatively secure system. Bitcoin is a blockchain application that everyone is familiar with, and it is also the most successful blockchain application so far. So far, Bitcoin has been running stably for 6-7 years. This system almost breaks everyone's concept of traditional financial system construction. First of all, it does not have any security protection facilities. Anyone who takes a machine and enters this network can join the network and work, and More than 80% of the machines in the entire Bitcoin network are almost bare metal. They have neither good security protection nor any firewall measures. Secondly, related to the design of Bitcoin, some of its data can track history and prevent tampering. and irrevocable.
Finally, this is also an obvious feature of blockchain. It is a very open system. There are already many open source underlying implementations for everyone to refer to or use, and it is very scalable. We have also been working hard to establish multi-center industry alliances or business alliances.alliance.

㈢ What does blockchain mean? What does blockchain mean?

Blockchain is actually equivalent to a disintermediated database, which is composed of a series of data blocks. Each of its data blocks contains information about a Bitcoin network transaction, which is used to verify the validity of the information and generate the next block.

Blockchain is a chain composed of blocks one after another. Each block stores a certain amount of information, and they are connected into a chain in the order in which they were generated. This chain is saved in all servers. As long as one server in the entire system can work, the entire blockchain is safe. These servers are called nodes in the blockchain system, and they provide storage space and computing power support for the entire blockchain system.

If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes, and these nodes are usually controlled by different entities. Therefore, it is extremely difficult to tamper with the information in the blockchain. Compared with traditional networks, blockchain has two core characteristics: first, data is difficult to tamper with, and second, it is decentralized. Based on these two characteristics, the information recorded in the blockchain is more authentic and reliable, and can help solve the problem of people's mutual distrust.

㈣ What is blockchain and how to introduce blockchain in a simple and easy-to-understand manner

Many people don’t know what blockchain is. Here I will give you a detailed introduction to blockchain. Chain is a new technology that subverts the old model. Just like people tend to ignore the invisible but indispensable oxygen, people often ignore the most important thing in the market economy, which is trust. Without trust, no transaction can be established.

In addition, different races, nationalities, cultures, religious beliefs, etc. will form a trust gap. Due to the lack of mutual understanding and necessary trust between strangers, it is difficult for transactions to occur. The market economy emerged in large numbers among strangers. The emergence and development of the market economy lies in the birth of a new mechanism, which solves the problem of trust between strangers.

The concept of blockchain was first proposed in a paper written by Bitcoin founder Satoshi Nakamoto in 2008. Blockchain can be understood as a kind of public accounting. Technical solution: All data will be open and transparent, without the need for a central server as a trust intermediary, thus ensuring the authenticity, immutability and credibility of information on a technical level. The immutability of data is very important.

Because the blockchain has the technical characteristics of large-scale expansion, open and transparent data, and because the data of each client is consistent, even if some clients are destroyed, it will not affect the reliability of data security. In particular, it can effectively solve the problem of trust between strangers, so this technology can be extended to all fields that can be digitized, such as digital currency, payment settlement, digital bills, proof of rights, credit information, government services, medical records, etc. If blockchain technology develops, it will be closely related to everyone in the future.

㈤ Will blockchain servers have higher requirements than ordinary traditional servers

For example, when many companies choose servers, they will consider the difference between blockchain servers and traditional servers? The following A brief analysis will be made.

To be precise, blockchain is a technical model, and the server is a physical hardware resource. There is no comparison between the two. But if you insist on talking about the difference, you can also look at the differences and connections between the two.

To talk about the difference between the two,

The biggest feature of blockchain is decentralization

For example, the most typical application of blockchain is Bitcoin. Bitcoin is a decentralized currency that is independent of any third party. It does not have a centralized issuer. It is generated by the calculation of network nodes. Anyone can run the Bitcoin client software on a computer to participate in the creation of Bitcoin, no matter where they are. Anyone can mine, buy, and sell.

All nodes of the blockchain are distributed in different places. Each node maintains and manages itself. It does not require a large area for centralized construction and requires dedicated management and maintenance. It can make full use of idle resources. Due to the distributed nature, the system is difficult to destroy, such as Bitcoin. Even the most powerful people or organizations in the world today cannot destroy the Bitcoin system based on the blockchain.

Traditional servers are centralized services

Traditional centralized servers, such as WeChat, Alipay, etc., are responsible for providing services to all clients by the servers behind their companies, and the clients are The server gets the service. If their server is paralyzed by an attack, your WeChat and Alipay will not be able to be used. For example, on May 28, 2015, Ctrip's server suffered an unknown attack, and its web version and mobile APP could not be used normally.

Does the blockchain still need a server?

To be specific, the blockchain is also divided into public chain, private chain and alliance chain. The most essential difference between the three is their different degrees of decentralization.

That is to say, the public chain is completely decentralized. The Bitcoin mentioned above belongs to the public chain. The private chain and the alliance chain are not completely decentralized, and there is still the shadow of centralization.

As mentioned above, the blockchain is a technical model and the server is a physical hardware resource. The two will inevitably have combined applications.

For example, a storage-type server combined with a blockchain can use cryptography to ensure the security of data transmission and access, thereby making the storage server data more secure.

If you need to know more about the blockchain server, you are welcome to consult the 10th power computing power leasing platform.

Does the public chain need a server?

Yes.
Public chain is also called "public chain". The difference between public and private lies in whether the nodes on the chain are controllable by oneself. The public chain corresponds to the private chain; Bitcoin and Ethereum are the most popular public chains nowadays. .
The public chain refers to anyone in the worldAnyone can enter the system at any time to read data, send transactions, and compete for accounting in the blockchain. Public blockchains are generally considered "completely decentralized" because no individual or institution can control or tamper with the reading and writing of data in it.
Public chains generally use token mechanisms to encourage participants to compete for accounting to ensure data security. In terms of application, public blockchain chains include Bitcoin, Ethereum, Hyperledger, most altcoins, and smart contracts. The ancestor of the public blockchain chain is the Bitcoin blockchain.
Currently, most Ethereum projects rely on Ethereum as a public chain. Ethereum is a new and open blockchain platform that allows anyone to build and use decentralized decentralized systems running through blockchain technology in the platform. application. Ethereum is a programmable blockchain that allows users to create complex operations according to their own wishes and can serve as a platform for many types of decentralized blockchain applications.
Except for financial applications, any application scenario with high requirements on trust, security and durability, such as asset registration, voting, management, Internet of Things and other 3.0 era applications, will be affected by the Ethereum platform on a large scale. .

㈦ Where can I find a more detailed explanation of blockchain applications

Blockchain applications include mathematical currency, payment and settlement, digital bills, proof of rights and interests, and bank credit reporting
Each The specific application is explained as follows:
1. Digital currency
At present, the most extensive and successful application of blockchain technology is the digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency. Digital currency has established digital currency transaction credit backed by sovereign currency. The greater the transaction volume and the more frequent transactions, the stronger the digital currency transaction credit foundation. Once the blockchain credit system is implemented globally, digital currency will become a gold-like global payment credit.
2. Payment and settlement
At this stage, settlement and payment of commercial trade transactions all rely on banks. This traditional method of conducting transactions through intermediaries requires the account opening bank, counterparty bank, central bank, and overseas bank. In this process, each institution has its own accounting system, needs to establish an agency relationship with each other, and needs a credit line; each transaction needs to be recorded in its own bank, and must also be cleared and reconciled with the counterparty, resulting in Transactions are slow and costly. Compared with the traditional payment system, blockchain payment is carried out directly by both parties to the transaction without involving intermediaries. Even if part of the network is paralyzed, it will not affect the operation of the entire system. If a universal distributed inter-bank financial transaction protocol is built based on blockchain technology to provide users with cross-border, real-time payment and clearing services in any currency, cross-border payments will become convenient and low-cost.
Take cross-border remittance as an example. If I open an account in a small bank in my country, I will open an account with another small bank abroad.Remittance, the transfer process under the traditional SWIFT system requires the following steps: First, I submit an application to the small bank to which I belong; second, the small bank submits an application to a large bank in the same country that has signed exchange terms; third, the large bank wire transfer Overseas cooperative banks; fourth, cooperative banks remit money to small overseas banks. Currently, the process takes anywhere from 10 minutes to two days, depending on the country. If you use blockchain-based settlement technology and place an order at a market maker while remitting RMB, a trading bank participating in the system in the world will receive the order, and the two parties will shake hands to complete the exchange. The average payment confirmation speed will be in a few seconds. Within seconds.
3. Digital bills
Digital bills are a brand-new bill presentation form developed by combining blockchain technology with bill attributes, regulations, and markets. It is completely consistent with the technical architecture of the existing electronic bill system. different. The core advantages of digital bills are mainly reflected in: First, the disintermediation of the value transfer of bills. In traditional bill transactions, bill intermediaries often use information differences to match. After point-to-point transactions are realized with the help of blockchain, bill intermediaries will lose their intermediary functions and reposition their identities. The second is to effectively prevent bill market risks. Due to the blockchain's non-tamperable timestamps and the fact that it is open to the entire network, once a transaction is made, there will be no default, thus avoiding the problems of "one vote selling more" for paper tickets and out-of-sync payment and endorsement of electronic tickets. Third, the system construction and data storage do not require a central server, eliminating the development costs of central applications and access systems, reducing the maintenance and optimization costs of the system under the traditional model, and reducing the risks caused by system centralization. The fourth is to standardize market order and reduce regulatory costs. The non-tamperable timestamp formed by the continuous connection of blockchain data greatly reduces the cost of regulatory review. The completely transparent data management system provides a trustworthy traceability path, and shared constraints can be established in the chain for regulatory rules through programming. code to achieve full coverage and hard control of regulatory policies.
4. Proof of Rights and Interests
Every node participating in the maintenance of the blockchain can obtain a complete data record. Using the characteristics of the blockchain's reliability and collective maintenance, the rights of the owners of rights and interests can be confirmed. For the need to store permanent records, blockchain is an ideal solution for scenarios such as land ownership and equity transactions. Among them, proof of equity is the field with the most applications currently. Equity owners can prove their ownership of the equity with their private keys. When the equity is transferred, it is transferred to the next owner through the blockchain system. The property rights are clear and the records are clear. The entire process does not require the involvement of a third party.
During a keynote address at the 2015 European Financial Journalism Awards for Excellence in Trading Technology in London, Nasdaq CEO Bob Greifeld announced that the exchange intends to use blockchain technology to manage its proxy voting system. Proxy voting is an important and time-consuming operation used by a listed exchange. The application of blockchain technology can allow shareholders to vote without having to attend the company's annual meeting. People can vote using their mobile phones, and save foreverVoting records. Blockchain technology is regarded as an advanced technology in the field of equity trading that can ensure transparent transactions in a shorter time.
5. Bank Credit Reference
At present, when developing commercial bank credit business, whether it is for enterprises or individuals, the most basic consideration is the financial credit of the borrower itself. Each bank uploads the repayment status of each borrower to the central bank's credit reference center. When inquiries are needed, the bank will download the reference from the central bank's credit reference center with the customer's authorization. There are problems such as incomplete information, inaccurate data, low usage efficiency, and high usage costs. In this field, the advantage of blockchain is that it relies on program algorithms to automatically record massive information and store it on every computer in the blockchain network. The information is transparent, difficult to tamper with, and has low cost of use. Commercial banks store and share customers' credit status in their own institutions in an encrypted form. When applying for a loan, customers do not have to go to the central bank to apply for a credit check, that is, decentralization. The lending institution can retrieve the corresponding information data from the blockchain. Complete all credit reporting work.
In short, blockchain has become one of the hot spots of innovation in the financial industry. However, as a new technology, blockchain also has considerable risks. The current settlement system based on blockchain technology is very sensitive to regulatory risks. If participants are worried about the uncertainty of regulatory policies, it may cause the payment system to collapse due to instability. In addition, since its operating rights are controlled by developers, the obvious technical disadvantage is that if the operator itself controls more than 51% of the computing power of the entire network, it can achieve double payment, leading to a breakdown of trust. This is also an important issue that needs to be solved during the application of blockchain technology.
