⑴ What is the country’s policy on blockchain?
Currently, the country has a recognized attitude towards blockchain technology and supports the research and development of independent blockchain technology. Encouraged, the country’s expectations for the blockchain industry are to be supported by specific implementation and application values. 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.
1. The composition of the blockchain system:
1. Data layer
2. Network layer
3. Consensus layer
4. Incentive layer
5. Contract layer
6. Application layer
2. Types of blockchain
1. Public blockchain
2. Industry blockchain
3. Private blockchain
3. Blockchain Features
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, each node realizes self-verification, transmission and management of information through distributed accounting and storage. 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 data of the blockchain 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.

⑵ Blockchain Encyclopedia: The Past and Present of Blockchain - 3.0 Era
The representative of the blockchain 1.0 era is Bitcoin, the representative of the 2.0 era is Ethereum, and The chaotic era of various copycats and air coins. Blockchain 3.0 is the era of consumer-level blockchain that has truly entered commercial and physical applications after the troubled times. The typical symbol is the emergence of tokens. The pass has brought about changes in traditional business models and production relations. The pass has moved from the digital world to the real economy and has begun to seek practical applications in various industries.
The pass has three elements, one of which is indispensable.
Pass: Pass can be circulated on a large scale in a network and can be verified anytime and anywhere; Certificate: As a proof of digital rights, the pass must be in the form of a number.An equity certificate that exists in the form of a digital currency must represent a right, an inherent and intrinsic value; value: the token must have economic value.
In this way, the meaning of "token economy" is not difficult to understand. The token economy is a large-scale group collaboration based on tokens. It maximizes the role of tokens, allows every role that creates value to share value fairly, fully mobilizes participation motivation, and forms a self-organizing form.
Major changes in the blockchain 3.0 era
The token economy has laid the theoretical basis and technical support for the large-scale application of blockchain, and the future world will also be transformed by it. Large-scale changes include:
1. Fragmented investment, fragmented income, subverting the traditional way of doing business on the Internet. In the traditional Internet era, it was impossible for ordinary people to participate in the investment of a company, but the emergence of blockchain allows ordinary people to make fragmented investments in a large asset. Assuming that Alibaba originally adopted blockchain for fragmented investment, then all fragmented shareholders who invested in Alibaba would be able to reap a return on investment that has increased thousands of times today!
2. Break the money-burning model of the Internet and make everyone a winner. The free model of the traditional Internet is essentially to obtain a large number of users through free products to form monopolies and barriers, and then make profits through advertising and value-added services on this basis. In the blockchain 3.0 era, project income is redistributed by issuing tokens to attract more early investors and community users. As the number of users holding tokens increases, the value of the tokens will become higher and higher, and community users, investors, and projects can all benefit from it. In this way, the money-burning model of providing free services in the early days of the traditional Internet can also be improved, and everyone will become a winner.
3. Breaking down the traditional corporate organizational hierarchy, self-organization may become a future trend. In the blockchain 3.0 era, through the establishment of distribution and collaboration mechanisms through smart contracts, it can be more efficient and accurate than enterprises. All token owners will naturally form a community. Everyone has the same goal - "to promote the development of the project and make it a success". They are all members of the community, contribute to the community, promote the value-added of the token, and thus gain benefits together. profit. From a philosophical perspective, this new self-organizing community of freedom, independence, and equality must be the future trend. Gojoy blockchain e-commerce is a blockchain self-organized community. Every consumer is a token owner and a fragmented investor, so he is very happy to co-create and build Gojoy value.
Therefore, we can look forward to the era of great development of the blockchain 3.0 token economy, and the existing ones may be subverted. What we need to be prepared for is to work hard to embrace the blockchain. If you want to seize the spotlight of blockchain and understand how to transform it, please leave a message to communicate and we will help you learn blockchain.Professional certification courses.

⑷ What does blockchain mean and how to make money
The meaning of blockchain and how to make money are as follows:
1. The meaning of blockchain: Blockchain is a After the information is confirmed by multiple parties, it is finally stored in multiple places. It is a tool that can solve credit problems during transactions.
2. How to make money with blockchain:
(1) Provide blockchain technology services. Form a corporate team to specialize in the development and application of blockchain technology, and provide your technical results to companies in need for use, or develop corresponding blockchain technology based on the needs of service recipients. A simple understanding is to be a middleman.
(2) Use blockchain technology to issue coins. This method is that the company acts as an issuer and releases a certain number of virtual coins for others to invest, such as Bitcoin, Litecoin, and Dogecoin. At that time, if you wanted to become an issuer, in addition to having blockchain technology, you also had to apply for a series of filing documents and materials such as business qualification certificates and currency issuance qualification licenses from relevant regulatory authorities. Otherwise, if you don’t have these documents, it would be fraud. . However, successfully preparing these documents will still test the strength and capital of the company. If the funds are not strong enough, it will be difficult to sustain.
(3) Blockchain knowledge paymentfee. In the early days of the blockchain market, many people did not understand what blockchain was and wanted to participate, which inevitably gave rise to a payment market for blockchain knowledge. Since this year, many public accounts with the theme of blockchain have appeared, and many paid blockchain courses and small investment circles have been born.
(4) Register to receive free candies. Candy is a token that the blockchain project team rewards early users in order to attract more users to join early use and dissemination. Similar to the early "Didi", in order to cultivate a large number of early users, a large number of free taxi tickets were issued to users.

With the continuous development of blockchain technology, it seems that many industries want to cooperate with blockchain With some connections, there is a popular saying in the world: "Those who get the blockchain will win the world." So is this blockchain really as amazing as everyone says? How will blockchain finally be implemented? Today, let’s first talk to you about the application practice of blockchain in the field of “e-commerce”.
First, let’s briefly review what is e-commerce? E-commerce was born in the 1990s. It is a business activity that uses information network technology as a means and commodity exchange as the center and side. We call e-commerce "EC" for short. Many people think it is the ultimate major commercial use of the Internet, so they call it an epoch-making symbol.
According to data from US market research company Forrester, by the end of 2018, China’s e-commerce market is expected to reach US$1.1 trillion, becoming the world’s first trillion-dollar e-commerce market. The report points out that by 2022, China's e-commerce market will reach US$1.8 trillion, far exceeding the United States and Japan.
With the expansion of e-commerce, it has also greatly promoted the development of logistics, customer service and other industries. But at the same time, it has also brought about many problems. According to big data from the e-commerce consumer dispute mediation platform, the number of complaint cases accepted in the first half of 2018 was year-on-year.An increase of 66.93%, a growth rate much higher than in previous years.
In order to solve the pain points of e-commerce in aspects such as counterfeit goods, logistics, integrity, and supervision, major companies and platforms are also showing off their skills and tricks. The most eye-catching one is our protagonist: blockchain. So how does it solve these problems?
First, supervise the production process of goods.
Second, trace and track the transportation of goods.
Third, guarantee product sales and after-sales service.
Fourth, protect user privacy.
The distributed e-commerce platform Bitcherry BCHC solves the platform trust crisis
Bitcherry BCHC is the world’s first distributed e-commerce platform. It is based on blockchain technology and is committed to To create a super ecology covering all aspects of clothing, food, housing and transportation. In the community ecology, all participants, such as users, merchants, super nodes, operating nodes, etc., use the token system for everyone's participation and economic sharing to open up the online and offline O2O e-commerce system, making the entire ecology healthy and autonomous. , develop healthily.
It is understood that the distributed e-commerce network has multiple payment methods, distributed sharing mechanisms, behavioral token incentives, distributed open platforms, multi-industry and multi-community access, and operating nodes around the world. , decentralized distributed business organizations, community self-propagation and ripples and other characteristics.
At present, consumer information is leaked, everyone has become a "digital labor", merchant profits are reduced, customer acquisition costs are increasing day by day, supply chain supervision is lacking, and product quality problems occur repeatedly, which is the problem for most centralized e-commerce companies. main pain points. Different from the centralized model of traditional e-commerce platforms, the underlying technology of distributed e-commerce platforms is a distributed accounting method that allows transaction data, dissemination, purchase, circulation and other behavioral data to be uploaded to the chain, making it open, transparent and non-tamperable. In distributed e-commerce based on blockchain technology, industry issues such as product traceability, logistics supervision, user evaluation and community incentives are all well-founded and well-founded. It returns data, traffic and value to the parties involved in the transaction, effectively solving the various shortcomings of centralized platforms.
To promote the implementation of blockchain in actual business scenarios, Bitcherry BCHC proposed "Blockchain 4.0"
According to the reporter's investigation, Bitcherry BCHC will adopt a two-stage implementation of "Blockchain 4.0" 4.0” target. Providing a public chain with high TPS and compatible with Ethereum smart contracts is the first phase of Bitcherry BCHC's measures to ensure the safe and efficient circulation of digital assets in the e-commerce ecosystem. In the second phase, Bitcherry BCHC will provide a platform to support e-commerce development.A dynamic public chain environment – an e-commerce vertical blockchain network platform, allows e-commerce operators to quickly realize digital operation transformation in the digital economy era and realize mutual diversion in the e-commerce ecosystem. In addition, the reporter learned that the large public chain environment will also provide a governance structure, including a smart contract-based complaint mechanism, reputation scoring, arbitration mechanism, etc., to prevent fraud and damage to the interests of consumers and digital asset investors, and ensure the e-commerce ecosystem compliance and healthy development.
In terms of technology, the Bitcherry BCHC public chain will combine blockchain and DAG technology to provide a chain network system, and the main chain will provide guarantee for the security of the entire system. Use signature algorithms, distributed storage, data operations, consensus mechanisms, message diffusion and other technologies to optimize the distributed e-commerce network architecture, and use a decentralized and non-tamperable structure to allow all participating entities in the Bitcherry BCHC ecosystem to establish a trust mechanism to achieve Second-level fast transaction verification by all parties is the main technical feature of the Bitcherry BCHC project.
⑺ The basic elements of blockchain include
1-Contains a distributed database
2-The distributed database is the physical carrier of the blockchain. The blockchain is the logical carrier of transactions, and all core nodes should contain a full copy of the blockchain data
3-The blockchain serializes blocks in time, and the blockchain is the entire The only subject of network transaction data
4-Blockchain is only valid for addition and invalid for other operations
5-Public and private key verification based on asymmetric encryption
6-Accounting nodes require that the Byzantine Generals Problem can be solved/avoided
7-The consensus process (consensus progress) is evolutionarily stable, that is, it is inconsistent in the face of a certain amount of conflicting data from different nodes. will crash.
8-The consensus process can solve the double-spending problem.
Five characteristics of blockchain:
Decentralization
Due to the use of distributed computing and storage, there is no centralized hardware or management organization, the rights and interests of any node The obligations are equal, and the data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system.
Thanks to the decentralization characteristics of the blockchain, Bitcoin also has decentralization characteristics [6].
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 information through the public interface. Develop related applications, so 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 operate freely and securely in a trustless environment.The exchange of data changes trust in "people" to trust in machines, and any human intervention has no effect.
Information cannot be tampered
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 not be allowed. is invalid, so the data stability and reliability of the blockchain are extremely high.
Anonymity
Because the exchange between nodes follows a fixed algorithm, the data interaction is trustless (the program rules in the blockchain will judge whether the activity is valid by itself), so the counterparty does not need to disclose it through the The identity method allows the other party to trust themselves, which is very helpful for the accumulation of credit.
⑻ What are the awards for the Blockchain Technology Contribution Award
The Blockchain Technology Contribution Award is used to recognize individuals and organizations that have made outstanding contributions in the field of blockchain technology. or institutional honorary awards. According to different selection criteria and purposes, the Blockchain Technology Contribution Award can be divided into the following categories:
1. Blockchain Technology Innovation Award: to commend outstanding achievements in blockchain technology research and development and innovation. Achieving individuals or teams. For example, Satoshi Nakamoto, the inventor of Bitcoin, was selected as the winner of the 2014 Blockchain Technology Innovation Award.
2. Blockchain Leadership Award: Commends individuals or organizations with outstanding leadership and influence in the blockchain industry. For example, Brad Garlinghouse, CEO of blockchain technology company Ripple, received the CoinDesk 2019 Blockchain Leadership Award.
3. Blockchain Application Innovation Award: Commends individuals, teams or organizations that have made outstanding contributions in the application of blockchain technology. For example, the 2018 Blockchain Application Innovation Award is sponsored by the Zhejiang Provincial Government and aims to commend units and individuals who have made outstanding contributions in the construction of the blockchain ecosystem, business applications, and social value enhancement in Zhejiang Province.
4. Blockchain Community Contribution Award: To recognize individuals or organizations that have made outstanding contributions in supporting and promoting the healthy development of the blockchain community. For example, Block.one and EOS.IO established a $10 million blockchain community contribution award fund for the EOS community at the 2019 EOS mainnet launch.
To sum up, the Blockchain Technology Contribution Award includes different awards such as Technology Innovation Award, Leadership Award, Application Innovation Award and Community Contribution Award. It aims to recognize those who have done well in the field of blockchain. individuals and organizations who have made outstanding contributions.
