⑴ What are the famous public blockchain chains in China

There are many such as Xiaoyi Blockchain and Laikelib, which look promising.

⑵ What are the three major public chains of blockchain?

Public chain, short for public chain, means that anyone in the world can read it, anyone can send transactions and transactions can Obtain valid confirmation of a blockchain in which anyone can participate in 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 3.0 respectively. Three stage.

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 release 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.

⑶ What areas are there now?Better companies in blockchain

There are already quite a few blockchain companies in China, although they are pitifully small compared to the number of companies in other industries. For example, Yingtang Zhongchuang is currently a company with a relatively good reputation, mainly providing blockchain underlying technical services and industry solutions. That is to say, an underlying blockchain is built and an adaptation layer is built on top, so that enterprises can quickly establish commercial applications.

⑷ Is there any reliable public chain in the blockchain industry?

Is there any reliable public chain in the blockchain industry?

In the blockchain industry, both practitioners and investors must be familiar with public chains. Whenever a new project is born in the industry, it must have something to do with the public chain. But in fact, looking at the entire blockchain industry, there are not many mature and stable public chains. Currently, there are three main system types in the blockchain industry: public blockchain, joint blockchain, and private blockchain.

Public blockchain is often referred to as a public chain in the industry. It means that any individual or group in the world can participate in the accounting and transaction process of the entire system, and at the same time, its transaction records can be effectively obtained by the system. Confirmed blockchain mainnet, in the industry, we usually call this publicly writable nature "open source". The public chain is the earliest and most widely used blockchain system in the industry.

United blockchain, also known as alliance chain, the alliance chain system is not open source, but multiple pre-selected nodes are designated as bookkeepers within a certain group, and each block is generated by all The pre-selected nodes jointly decide that other nodes can participate in transactions but have no right to participate in the accounting process. It is essentially similar to the custody accounting in the financial industry and can be called a "semi-centralized" blockchain system. This system is more stable, but is not suitable for wide-scale popularization and application.

Private blockchain is a private chain. This kind of system is more closed, and simply uses the underlying technology of the blockchain for the accounting process. However, its network system is not open source, and developers have exclusive writing rights. The developer here can be a company or an individual. Currently, many traditional financial industries want to try private chain development, but their application products are still being explored.

Among the above three system types, the public chain system is undoubtedly the one that attracts the most attention from the industry. Compared with the other two types, the public chain has the advantages of open source, decentralization, and wide ecological scenarios, and is also more conducive to global promotion and layout. However, due to various reasons such as technology, capital, and time, the industry’s public chain research situation is generally not optimistic.

The three most well-known public chains in the industry, the Bitcoin public chain, the Ethereum public chain, and the EOS public chain, all have different problems. The closed system of the Bitcoin public chain forms an island of value, which cannot be solved by a hard fork; the problems of Ethereum transaction congestion and excessive handling fees are always difficult to solve; and within EOS, due to insufficient ecological scale, it is difficult to support excellent ecological applications. At the same time, the CPU Problems such as skyrocketing and insufficient memory gradually emerged..

In short, in order to determine whether a public chain is reliable, you need to understand whether the operating logic of its public chain network itself is stable, whether its ecological structure capacity is sufficient, whether its community consensus is strong, and whether its applications Whether the scene has long-term hematopoietic function, etc. Of course, the blockchain industry is currently in the development and exploratory stage, and it will take time to prove a reliable and stable public chain.

⑸ At present, what are the more reliable public blockchain chains in China?

In the past, whenever we mentioned blockchain, we would always think of foreign products, such as Ethereum. Square, but when I talk about this topic today, I will think more about China’s own blockchain technology.

At present, the mature applications of blockchain technology are more concentrated in some public chain projects, because many application projects need to be developed based on this, so I think that the current global One of the general directions for implementation is public chain projects. It is still too early to talk about maturity. After all, Bitcoin and Ethereum are still very congested. There are still many old problems that have not been solved, and many new problems will arise. The more well-known ones are Bytom, Ulord (the project is abroad, but the technology is provided by the domestic company Hunan Tianhe Guoyun Co., Ltd.), Quantum Chain, Xiaoyi NEO, Gongxinbao, etc.

Ulord is a point-to-point value transfer public chain. By building the underlying blockchain architecture and digital resource distribution protocol, it supports third-party developers to build their own applications on top of its open source protocol, and interacts with many industries. Partners work together to build a complete ecosystem of blockchain technology and applications.

Based on various rules and protocols created by Ulord, it is convenient to graft various digital resource application scenarios including text, pictures, music, videos, software, etc., and provide direct communication between information creators and consumers. docking platform. Third-party developers can build their own economic systems in Ulord, or they can focus on building various applications around Ulord, using the UlordToken in Ulord as in-system credentials.

For example, an experience sharing platform can be built on Ulord. Experience sharers price the published experiences. People who obtain experience information trade on the platform, and every fee paid to the experience sharers will be paid immediately. Account; product promoters can publish advertisements on Ulord, price the advertisements, and people who are interested in the advertisements and click on the advertisements can get certain benefits, etc. Different from the previous model where information transmission requires the help of platforms or other centralized institutions for dissemination and profit, the intermediate links are removed, and information providers and consumers are directly connected through Ulord, ensuring the maximization of the interests of the original creator.

⑹ 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 computing platform for distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc.New application models of machine technology.

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. Each data block generated 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.

(6) What are the reliable csdn extensions of the public blockchain chain? Read

According to the different degrees of centralization of blockchain networks, blockchains are divided into three different application scenarios:

1. The entire network is open and there is no user authorization mechanism. Blockchain is called a public chain;

2. Allows authorized nodes to join the network and view information based on 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.

⑺Which domestic blockchain company is the best

First of all, I will introduce the well-known domestic blockchain companies, and then I will personally evaluate which one is better, specifically. You can judge for yourself.

1. Bubi Blockchain Company, this company provides blockchain underlying technical services and industry solutions. That is to say, an underlying blockchain is built and an adaptation layer is built on top, so that enterprises can quickly establish commercial applications. underlying blockThe chain is developed by itself, the consensus mechanism is pbft, tps is 5,000 transactions per second, UnionPay transactions per second is 2,000, and Bitcoin transactions per second are 7. Of course, the underlying architecture is different, and the performance is different. , because Bubi is a commercial blockchain, so it pays more attention to performance. At present, Bubi is mainly used in the fields of digital assets, supply chain finance, supply chain traceability, publicity and notarization, etc.

2. Bu Meng Blockchain. Theoretically speaking, Bumeng should be said to be Bubi's product line, but Bubi mainly does private chain, and Bumeng does alliance chain, so separately speaking, Bumeng is Bubi's layout in digital assets. The underlying technology is Bubi blockchain, but the blockchain is encapsulated according to the scenario and provides API interfaces for enterprises. Enterprises issue their own assets on it and carry out the free circulation of assets according to the characteristics of the blockchain. Currently, Sunshine Some companies such as Insurance, Qianxiang Finance, Zhongtuobang, Haohuoah, etc. have connected. The assets include insurance policies, points, financial products and the like. In the end, it is estimated that this platform will break down the barriers between assets, and finally users can freely use and transfer these assets. This is an interesting way of playing in the blockchain industry, because it has the openness of the public chain and the security of the private chain.

3. VeChain. VeChain is a commodity ID management cloud platform based on blockchain technology. It provides enterprise-level users with commodity asset management, tracking and traceability, anti-counterfeiting verification, and new types of products in the form of BaaS. Supply chain management, etc. To simply understand, VeChain has done the “supply chain traceability” aspect of the Bubi blockchain.

4. Tongxin Huzhu, Tongxin Huzhu is a mutual aid guarantee platform that puts some relevant information about mutual aid insurance into the blockchain. Users can apply to become nodes, participate in bookkeeping, and maintain their own data.

5. Xiaoyi, Xiaoyi is based on blockchain technology, digitizing the assets and rights of the physical world, and decentralizing financial services such as registration and issuance, transfer transactions, clearing and delivery through a peer-to-peer network. network protocols.

These are probably the five well-known blockchain companies in China, and I personally recommend Bumeng.

First, Bumeng uses the underlying technology of Bubi blockchain, which is relatively promising in the industry and has the most practical applications in China. Enterprises can access it at low cost (just call the interface, it seems) It is also free) using blockchain technology, and you can also use the resources inside. Think about being on the same chain with many companies. In the future, resource docking will not make it easy for users to convert.

Second, VeChain and Tongxin Huzhu focus on a certain field and do not provide underlying technology and industry solutions. In other words, if you are in this industry or can use it for upstream and downstream industries, It cannot be used in other fields. Taking the field of mutual aid and security as an example, both Zhongtuobang and Zebra Club chose Bumeng. Of course, you can consider it if it is an investment.

Third, Xiaoyi, why don’t you recommend Xiaoyi? Because Xiaoyi is an open source project.Everyone knows the business environment, especially when the industry has just begun to develop. The domestic market is different from that abroad. Xiaoyi has gone through two rounds of ICOs, which will be a great worry in future operations. Moreover, Xiaoyi has not yet implemented practical applications. I have built a platform for Fada that no company is using yet (guess it may be related to the open source factor, who dares to fully open their data), of course, Xiaoyi’s open attitude is worth encouraging, although I guess the code The advantages and disadvantages are clearly understood by peers, but they are not relatively unclear.

Fourth, why is Bubi not recommended? Bubi also raised 30 million some time ago, because Bubi is more open and has more resources. Of course, if the business has high privacy requirements, it can also be done. Choose Bubi Blockchain.

Finally, for the sake of my hard work in answering so many questions, choose me!

⑻ What are the more reliable blockchain projects now?

MITx’s goal is to build an enterprise-level blockchain platform as a service (BPaaS) and an affiliated blockchain Chain application market. Enterprise-grade blockchain essentially enables businesses of all sizes to design, deploy and run distributed ledgers on our platform. You can even create your own blockchain innovation laboratory, equipped with the necessary infrastructure and a complete set of integrated tools, to enable low-cost blockchain application test drives. This is a good blockchain experiment and incubation platform. .
FASHIONET, as the world's first blockchain project aimed at transforming the fashion industry and establishing a new fashion ecology, attracted the attention of the fashion industry and blockchain circles upon its debut. Kim Chung-Ho, the Korean technical leader of the project, said in an interview: "Fashion Planet organically combines blockchain technology with fashion AI, complementing each other and relying on each other to maximize their respective functional characteristics. Solve a series of pain points in the fashion industry and realize the transformation of the fashion industry.
At present, these two projects are developing very well.
