1. What are the requirements for hardware architecture for practical applications of blockchain?

Generally, the requirements for hardware architecture for practical applications of blockchain are not too high, but different applications The hardware requirements are also different.
For example, European Crowdfunding is a new crowdfunding platform developed based on blockchain technology, which combines physical assets with digital currency. Each crowdfunding project will issue a different digital currency, and the digital currency serves as an asset certificate. exists and can be traded freely in the market.

2. What is a blockchain host?

Triangular host. Blockchain hosts are triangle hosts. The Triangle Host is a hardware product based on blockchain technology launched by the Acute Angle Cloud team. Intelligent hardware to obtain digital assets through distributed cloud storage and cloud computing to share idle hard disk space and bandwidth.

3. What exactly does blockchain refer to, and what disciplines or fields does it involve?

What is blockchain? Blockchain applications mainly include Internet technology and information content encryption algorithms, combined with appropriate rules and systems, to form a reliable system software infrastructure. The infrastructure here can be interpreted as the online environment. What does this trust mean? Database encryption methods can be divided into symmetric encryption algorithms and symmetric encryption. Symmetric encryption has higher security but slower response speed. The elliptic curve encryption technology used in blockchain technology is the fastest method among non-asymmetric encryption algorithms. Therefore, the encryption algorithm of blockchain technology is very powerful and it can ensure the uniqueness of the customer's identity. In addition, the information in blockchain technology is also protected by data encryption and is difficult to forge.

The blockchain system avoids the above three problems. The behavior of each node is different from other nodes. The behavior of the node is determined by the program in advance. The regulations are stipulated, and the encryption algorithm ensures that every connection point cannot violate the regulations. This is the connotation of grassroots democracy in the system. Blockchain applications are generally used to build trading software, and it is necessary to ensure that the transaction information content is authentic, valid, traceable and cannot be tampered with. Each transaction information is verified and stored in a zone, and the blockchain information is encrypted through hashing technology to ensure that the information cannot be forged. This blockchain forms a transmission chain in chronological order. Each node has complete blockchain information. If the information content of some nodes is destroyed, the blockchain information will not be affected. This type of archival information method is called a distributed ledger.

In such a distributed ledger of blockchain technology, the actual operation of adding a new record and linking it to all nodes must be carried out according to certain rules, otherwise nothing will be true and effective. . This standard is the consensus mechanism of blockchain technology. In essence, a fair and equitable consensus mechanism should allow all nodes to improve the blockchain. When the content of the increased blockchain is different, it should be negotiated according to certain standards until the content of a certain blockchain is accepted., then all connection points copy this blockchain. Instead of equalizing the amount, not all nodes can be added to the blockchain. Instead, a point eligible to be added to the new server block is selected based on certain criteria and the blockchain information added by the node is copied. Blockchain technology uses the latter, and since the election rules are open and transparent, the election ceremony will become the entire competition process.

4. What is the country’s policy on blockchain?

Currently, the country has a recognized attitude towards blockchain technology and supports and encourages the research and development of independent blockchain technology. Yes, the country’s expectation for the blockchain industry is to be supported by specific implementation and application value. The future expectation for blockchain is that blockchain will become a breakthrough for independent innovation of core technologies. And blockchain is legal. 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 being unforgeable, leaving traces throughout the process, traceable, open and transparent, and collectively maintained.

5. What is blockchain? If you don’t understand blockchain technically, will it have any operational impact?

Blockchain is a distributed system of data storage, point-to-point communication, and consensus. Mechanism, data encryption and other new application models of electronic information technology. Its essence is distributed system data information, and with the conclusions it brings, it goes to "blockchain technology". Blockchain applications can be used in many situations in life. Let’s take a look at the blockchain applications.Analyze it!

Technology is a double-edged sword. Just like nuclear technology is a physical technology, blockchain technology is an underlying technology in terms of technology. Nuclear technology can be used as nuclear bombs and nuclear power generation. Similarly, digital currency can be used as a management method for industrial chains and life factors, which may promote more sustainable social development, and may also be used by evildoers as the most convenient means of crime.

Including blockchain coins, if my country adopts legal digital currency, blockchain coins can be decentralized. The blockchain that supports the operation of Bitcoin is blockchain technology, but the alliance chain usually has one or several companies as the core control alliance, which becomes decentralized.

6. Characteristics of blockchain, looking forward to answers

Blockchain technology is very popular now, but many people don’t know much about blockchain. Today’s editor is here Let’s talk about the characteristics of blockchain.

It mainly includes the following six characteristics:

Decentralization

Due to the use of distributed computing and storage, there is no center The hardware and management organization are standardized, and any node has equal rights and obligations. The data blocks in the system are jointly maintained by the nodes with maintenance functions of the entire system. Stopping work of any node will not affect the operation of the entire system.

Trustless

All nodes in the system can conduct transactions without trust, because the operation of the database and the entire system is open and transparent. Nodes cannot deceive each other within the rules and time range of the system. .

Openness

The system is open. In addition to the encryption of the private information of the transaction parties, the blockchain data is open to everyone and anyone can Blockchain data can be queried and related applications developed through public interfaces, so the information of the entire system is highly transparent.

Autonomy

The blockchain adopts consensus The specification and negotiation enable all nodes in the entire system to exchange data freely and securely in a trustful environment, turning trust in people into trust in machines, and no human intervention will work.

Information cannot be tampered

Once the information is verified and added to the block chain, it will be stored permanently. Unless the nodes in the system exceed 51%, the modification of the database by a single node is invalid, so the data of the block chain is stable The accuracy and reliability are extremely high.

Anonymity

Since the replacement between nodes follows a fixed algorithm, its data interaction does not require trust (the program rules in the blockchain judge whether the activity is Effective), the transaction object does not need to disclose the identity to trust the object, which is very helpful for the accumulation of credit.

7. What are the characteristics of blockchain technology

Blockchain technology Its four major characteristics include: decentralization; trustlessness; scalability; anonymity. Decentralization: Due to the use of distributed computing and storage, the blockchain system does not have centralized hardware or management organizations, so any nodeThe rights and obligations are equal, and the data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system. Openness: The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface. Therefore, the entire System information is highly transparent. Autonomy: The blockchain adopts consensus-based specifications and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to exchange data freely and securely in a trustless environment, so that trust in "people" is exchanged. It has become a trust in the machine, and no human intervention will work. Information cannot be tampered with: Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node will be invalid, so the area The data stability and reliability of blockchain are extremely high. Anonymity: Since the exchanges between nodes follow a fixed algorithm, the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself), so the counterparty does not need to reveal its identity to the other party. Generating trust is very helpful for the accumulation of credit. Reliability: The data on the blockchain saves multiple copies, and the failure of any node will not affect the reliability of the data. The consensus mechanism makes modifying large numbers of blocks extremely costly and almost impossible. Destroying data is not in the self-interest of important participants. This practical design enhances the reliability of data on the blockchain and global circulation: blockchain assets are first based on the Internet. As long as there is the Internet, blockchain assets can be circulated. The Internet here can be the World Wide Web or various local area networks, so blockchain assets are circulated globally. As long as there is the Internet, blockchain assets can be transferred. Compared with centralized methods, the transfer fees for global circulation of blockchain assets are very low. For example, the early transfer fee for Bitcoin was 0.0001 BTC. Compared with traditional transfers, Generally speaking, blockchain assets arrive very quickly. It usually takes a few minutes to an hour to arrive.

8. What technology will solve the problem in the future labor environment

In the future labor environment, blockchain technology will solve the problem of reliable transmission of trust and value on the Internet.

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 in the hands of different subjects, so tampering with the information in the blockchain is a problem. An extremely difficult thing.

Characteristics of blockchain:

1. Decentralization.

Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, through distributed accounting and storage, each node realizes information self- Validate, deliver and manage. Decentralization is the most prominent and essential feature of blockchain.

2. Openness.

The foundation of blockchain technology is open source. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data through the public interface. and develop related applications, so the entire system information is highly transparent.

3. Independence.

Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), the entire blockchain system does not rely on other third parties, and all nodes can automatically and securely operate within the system. Verification and exchange of data do not require any human intervention.

4. Security.

As long as you cannot control 51% of all data covering nodes, you cannot arbitrarily manipulate and modify network data. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.

5. Anonymity.

Unless there are legal requirements, technically speaking, the identity information of each block section does not need to be disclosed or verified, and the information transfer can be done anonymously.
