(1) Extended reading of representative products of blockchain:

Blockchain is far more than just a technology, behind it involves The spirit of "multi-party collaboration". In modern society, manyThings 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. If you do things honestly, you will get the benefits you deserve. If you cheat, it will 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".

2. What are the classifications and applications of blockchain projects

From the current mainstream blockchain projects, blockchain projects mainly fall into four categories: Category 1: Coin type; second type: platform type; third type: application type; fourth type: asset tokenization.

Coins mainly serve as the "medium of exchange" in the field of blockchain assets. The medium of exchange refers to general equivalents, such as gold and silver notes in the past. (Trade blockchain assets on "Bihui Exchange")

Platform projects refer to the establishment of technology platforms to meet the development of various blockchain applications, which can reduce the cost of developing applications on the blockchain. threshold.

The scope of application projects is relatively wide, covering many fields such as finance, social networking, games, property rights protection, etc. It is also the fastest growing field of blockchain assets.

The asset tokenization project refers to the blockchain mapping of physical assets, that is, the physical assets are put on the chain. Currently, there are no more than 10 varieties.

01 Currency

The first category is currency projects, which are also the earliest blockchain projects. Currency projects mainly include projects such as Bitcoin and Litecoin. In addition, there is another type of asset that has the characteristics of anonymity. Its main functions include realizing payment while protecting the privacy of both parties. The well-known ones include Dash, Monero and Big Zero that use zero-knowledge proof. Coin (Zcash), etc. Currency mainly serves as the "medium of exchange" in the blockchain asset field. The medium of exchange is the general equivalent that you use to exchange for goods. For example, in the past, gold, silver, and banknotes could be used as media of exchange. There are currently more than 2,100 types of digital assets in the world, and the number of currency blockchain projects has grown rapidly recently. As of June 2018, Bitcoin still has the largest market value.

02 Platform Category

The second category is platform blockchain projects. The main function of platform blockchain projects is to establish a technology platform to meet the needs of various blockchain application development. The required technical requirements; simply put, platform applications allow developers to directly issue digital assets on the blockchain, write smart contracts, etc. A smart contract is a computer program that runs on a blockchain database and can be automatically executed under conditions set by its source code.

For example, if you develop a smart contract based on a house rental agreement on the blockchain, when the owner receives the rent, it will trigger automatic execution and give the apartment's security key to the tenant.

The main function of platform blockchain projects is to establishThe underlying technology platform allows developers to develop applications on the underlying technology platform. A considerable part of the platform is still under development. As of June 2018, the largest market value is Ethereum.

03 Application Category

The third category is application blockchain projects. Application projects are developed based on blockchain development platforms (such as Ethereum) and can solve various problems in the real economy. Blockchain projects that address many issues in the field.

For example, the blockchain-based prediction platform Augur, the blockchain-based computing power trading platform Golem, the blockchain-based luxury traceability platform VeChain, and the blockchain-based asset exchange and transfer services OmiseGo. Using blockchain technology, these projects can better solve trust issues, cross-border circulation and other issues. At the same time, using smart contracts and tokens on the blockchain, automatic execution can be better realized, greatly improving the efficiency of social and economic activities. efficiency. The scope of applied blockchain projects is relatively wide, covering many fields such as finance, social networking, games, property rights protection, etc. It is also the field where the market value of blockchain projects is increasing the fastest.

04 Asset Tokenization

The fourth category is asset tokenization blockchain projects. Asset tokenization refers to linking blockchain assets to physical assets such as gold and U.S. dollars. , is a blockchain mapping of physical assets. As of February 2018, there are no more than 10 varieties. The more typical representatives are USDT, which is benchmarked against the US dollar, and Digix Dao, which is benchmarked against gold. Each DigixDAO token represents 1 gram of London gold. Silver Market Association certified gold. Asset tokenization has the advantages of convenient transactions and safekeeping. First, asset tokenization makes transactions easier. Because blockchain assets can be split, they have better liquidity.

For example, currently the real estate needs to be transferred as a whole. If the real estate can be tokenized, it can be purchased in pieces, making transactions more convenient. Secondly, tokenization of physical assets is more conducive to safekeeping. In physical transactions such as gold, it is easy to cause wear and tear and cause losses. However, after tokenization of physical assets, there is no need for physical transfer, which is more conducive to the custody of physical assets.

3. What are the domestic blockchain games?

1. CryptoRabbit – Xiaomi’s “Blockchain Game Project” 2. Dongle – Linekong’s “Blockchain Game” Project" 3. Blockcat - 360 "Blockchain Game Project" 4. NetEase Lucky Cat, Planet - NetEase "Blockchain Game Project" 5. Leitz - Dog Network "Blockchain Game Project" Chongqing anonymous technology is still possible, and many are doing it

4. What are the three major public chains of blockchain

Public chain, the abbreviation of public chain, means that it can be read by anyone in the world Anyone can send a transaction and the transaction can be effectively confirmed. Anyone can participate in the blockchain of the consensus process.

1. The top three public chains in the world
BTC, ETH, and EOS (by market capitalization) are three heavyweight products, representing Blockchain 1.0, Blockchain 2.0 and Blockchain respectively.3.0 Three stages.

1. Bitcoin BTC (Blockchain 1.0)
Bitcoin has emerged as a new type of digital currency and global payment network since its birth in 2009. BTC is also the most successful and mature application of blockchain. , now in many situations, BTC is much more famous than blockchain.

2. Ethereum ETH (Blockchain 2.0)
In layman’s terms, Ethereum is an open source platform digital currency and blockchain platform that provides developers with a platform to build and publish applications on the blockchain. . Ethereum can program, decentralize, guarantee, trade anything, vote domain names, financial exchanges, crowdfunding, company management contracts and most agreements, intellectual property, and hardware-integrated smart assets, etc.

3. Yuzu EOS (Blockchain 3.0)
EOS appears as an enterprise-level blockchain operating system based on Bitcoin and Ethereum, which is easier to use and more powerful than the former. EOS provides all application developers with many functions such as database account permission settings, execution scheduling authentication, and network communication.

2. The world's three major exchange public chains: Huobi Chain, Binance Chain, and OKEx Chain OKChain
1. Developed by Huobi Chain, the world's largest trading platform, Huobi Chain is An independently innovative supervised blockchain operating system for the financial field, based on blockchain global asset digitization and financial market infrastructure. At the same time, based on the consideration of injecting the long-term value of HT into a unified value carrier, HT will serve as the only underlying token of the Huobi public chain.
2. Developed by Binance, the world's second largest trading platform, Binance Chain started early in application and is currently mainly circulated on DEX and asset chains. Binance Chain is a digital asset creation and exchange platform, with BNB as the main chain token
3. Developed by OKEx, the world's third largest trading platform, OKChain is a more scalable, high-transaction processing capability trading and smart contract platform, OKChain Developed based on Cosmos-SDK, the consensus uses DPOS. OKB is the underlying token of the OKEx ecosystem.

5. What are the public blockchain chains?

Blockchains include public blockchains, joint (industry) blockchains, and private blockchains. Public chain peer-to-peer electronic cash system: Bitcoin, smart contracts and decentralized application platform: Ethereum.

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 cryptographic methods related to each other. Generated data blocks, each data block contains a batch of bitsThe information of currency network transactions is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

(5) Extended reading on representative products of blockchain

According to the different degrees of centralization of the blockchain network, there are three types of blockchains in different application scenarios:

1. A blockchain that is open to the entire network and has no user authorization mechanism. It is called a public chain;

2. Authorized nodes are allowed to join the network and can view information according to their permissions. It is often used in inter-organizational blockchains, called alliance chains or industry chains;

3. All nodes in the network are in the hands of an organization, which is called a private chain.

Consortium chains and private chains are also collectively called permissioned chains, and public chains are called non-permissioned chains.

Blockchain Characteristics

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.

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. All nodes can automatically and securely verify and exchange data within the system without the need for any human intervention.

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

5. Anonymity. Unless required by legal regulations, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be carried out anonymously.

6. Blockchain, 4 types, how much do you know

——Hello, I am mentality, focusing on sharing my understanding of blockchain and investment thinking. hope this helps.

Based on different usage requirements and scenarios, blockchain is divided into 4 types: public chain, alliance chain, private chain and hybrid chain.

1. Public chain

Public chain means that anyone at any node in the world and at any geographical location can enter the system to read data, send transactions, and compete. Blockchain that participates in consensus such as accounting. No institution or individual can tamper with the data in it, so the public chain is completely decentralized.

Bitcoin and Ethereum are both representatives of public chains. Public chains generally issue tokens (Ttoken) to encourage participants to compete for accounting (i.e. mining) to ensure data security and consensus updates.

Bitcoin generates one block every 10 minutes on average, and its POW mechanism is difficult to shorten the block time. The POS mechanism can shorten the block time relatively speaking, but it is more likely to cause forks. So the transaction needs to wait for more confirmations before it is considered safe.

It is generally believed that a block in Bitcoin is secure enough after 6 confirmations, which takes about an hour. Such a confirmation speed is difficult to meet commercial-level applications. Therefore, public chains such as ETH and EOS that support more writing speeds are constantly developing.

2. Alliance chain

Alliance chain refers to a blockchain that is jointly participated and managed by several institutions, with each institution running N nodes.

The data of the alliance chain only allows different institutions in the system to read, write and trade. The PKI-based identity management system transactions or proposals are initiated through digital certificates and are verified by the joint signature of the participants. A consensus is reached, so there is no need for proof of work (POW), and there is no digital currency (token), which improves the efficiency of transaction completion and saves a lot of computing costs (computing hardware investment and electricity energy consumption).

Normally, nodes participating in the alliance chain will be divided into different read and write permissions, which can support more than 1,000 data writes per second.

3. Private chain

Unlike the public chain, which is completely decentralized, the private chain’s access rights are controlled by an organization, and the participation qualifications of each node are controlled by the organization. Authorization control.

Since the participating nodes are limited and controllable, private chains often have fast processing speeds and can support more than 1,000 data writes per second, while reducing the transaction costs of internal nodes.

Nodes can participate under real names and therefore have financial attributes to confirm identity. The value of the private chain is mainly to provide a safe, traceable, non-tamperable, and automatically executed computing platform, which can prevent both internal and external security attacks or tampering of data, which is difficult to achieve in traditional systems.

The application scenarios of private chains are generally within enterprises, such as inventory management of branches, summary statistics of data from various places, etc. It can also be used in areas that can be supervised by the public, such as government budgeting and execution. Large financial groups are also currently inclined to use private chain technology.

4. Hybrid chain

When the respective advantages of public and private chains are combined, a hybrid chain will appear. The development of hybrid chains is difficult, but the prospects are broad.

In the future market, there will definitely be giant companies that develop underlying technologies and protocols. These giant companies will set up public chains, private chains or alliance chains for different purposes.Based on the different needs for performance, security and application scenarios, it is then grafted onto applications in different industries. For example, a communication public chain that supports high concurrency, a payment alliance chain that focuses on security, etc.

(Thanks for reading)

A like and a follow are the greatest support for me. See you tomorrow.

7. What are the chains of the blockchain?

Let’s learn about the chains of the blockchain together. Let’s go.

1. Public Blockchain

A blockchain open to everyone and anyone can participate.

@Bitcoin is the representative.

The public chain is completely decentralized and not controlled by any organization. The ledger is completely open and transparent, and anyone can participate in the maintenance and data reading of the blockchain.

2. Consortium Blockchain

The nodes participating in the blockchain are selected in advance and are open to specific organizations or groups.

@R3CEV is the representative of the alliance chain.

The alliance chain is open to specific organizational groups, which means that the nodes participating in the blockchain are selected in advance, and there are likely to be good network connections between the nodes.

Features:

(1) The transaction speed is very fast;

It can achieve good connections between nodes and only requires a few It can maintain operation at a low cost, its transaction speed is very fast, and a small number of nodes also have a high degree of trust, and each node does not need to be verified.

(2) Transaction costs are significantly reduced or even zero;

When a centralized entity alliance handles accounting, there is no need for a high incentive mechanism. It can also prompt nodes to keep accounts, so the handling fee will be reduced a lot, or even zero.

(3) Data can have a certain degree of privacy;

Data reading permissions in the alliance chain are hierarchical, external and internal, as well as between internal nodes. The permissions can also be different. The alliance chain also means that the application scope of this blockchain will not be too wide, and it is not like the network spread effect of Bitcoin.

3. Private Blockchain

Open to individual individuals or entities. The participating nodes are only themselves. The access and use of data have strict permission management. Generally, For internal audit use.

@Since it is a control center that has the final say, the numbers insideThe data cannot guarantee the characteristics that cannot be changed, and there is not much protection for third parties and the public. It is generally used for internal audits.

Blockchain knowledge points, bit by bit.

8. Blockchain Encyclopedia: The Past and Present of Blockchain - 3.0 Era

The representative of the blockchain 1.0 era is Bitcoin, and the representative of the 2.0 era is Ethereum. And the troubled times 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: The 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 and interests, the pass must be a certificate of rights and interests that exists in digital form, and it must represent It is 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 trend of blockchain and understand how to transform into blockchain, please leave a message to communicate and we will take you to learn the blockchain professional certification course.
