1. What is the public chain in the blockchain?

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. 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.

(1) Extended reading on the basic public chain 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 and is called alliance chain or industry chain;

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.

2. What are the three major public chains of blockchain?

Public chain, the abbreviation of public chain, refers to the worldA blockchain that can be read by anyone, anyone can send transactions, and transactions can be effectively confirmed and 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.

3. 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 be discussed with the company more or lessThere are some connections in the 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.

4. What currency is mbtc?

The full name of MBTC coin is MBT Chain. The Chinese name of MBTC coin is Meibit. MBTC is a decentralized blockchain. Data innovation ecosystem. MBTC is operated by Singapore My BesThe global decentralized data blockchain ecological network initiated by the t Foundation (non-profit) is positioned to provide commercial-level blockchain infrastructure services in the big data industry. On the one hand, we build an enterprise-level blockchain basic public chain, and on the other hand, we build a highly scalable application business support system on it. Among them, the lowest level is MBT Chain, a public blockchain focused on the data industry, which maps the real world of behavioral data onto the blockchain. Through cross-platform, cross-enterprise, cross-industry, and cross-border interconnected collaboration, we can create a new business model and provide decentralized data credit services to collaboration participants.

MBTC was initially sold as ERC20 tokens on the Ethereum platform, and the maximum total number of tokens is X=2 billion. The smallest unit of MBTC is 10-18MBTC. After MBT Chain is officially launched, users holding Ethereum ERC20 MBTC can exchange for the equivalent amount of MCC10 MBTC in the MBT Chain network based on the certificate, and at the same time, Ethereum's ERC20 MBTC will be destroyed. The total amount of MBTC is 2 billion, which is divided into five parts: private equity share, foundation share, founding team and development share, community ecological construction, and super node reward share.

MBTC is a digital asset on the MBT Chain public chain. MBTC is a digital asset used by individual users. It not only has circulation value, but is also an essential encrypted digital asset based on the MBT Chain public chain application. To develop, certify applications, and use on-chain services (such as mining fees for on-chain transfers) on the MBT Chain public chain, you need to pay or burn MBTC. MBTC is the only token used to run applications on the chain.

As MBT Chain cooperates with more and more customers and data sources on the public chain, and the amount of data uploaded and transactions increases, MBT Chain can receive more information. For more commissions, the team will regularly use 15% of the commission income to repurchase MBTC and destroy it according to the current secondary market price.

As an alliance pass, MBTC has risks such as force majeure in its transactions. Therefore, MBTC cannot guarantee absolute profits or losses. The MeBit team attaches great importance to the financial security of all users and strives to protect the interests of users, but cannot make any guarantee of accuracy of predictions, nor can it guarantee any absolute gains or absolute losses. The Mebit development and operation team believes that there are numerous risks in the development, maintenance and operation of Mebit, many of which are beyond the control of the Mebit development and operation team.

5. What is a public chain and what is it used for?

Public Blockchain, also known as "public chain", means that anyone in the world has permission to read A consensus blockchain that obtains, sends and obtains valid confirmations. It does not require registration,The network can be accessed anonymously with authorization, and it has the characteristics of decentralization, neutrality, openness, and non-tamperability. It is suitable for virtual currency, Internet finance and other fields.

It can be said that the public blockchain is the earliest blockchain in the world.

Currently, most blockchain projects use EOS, Ethereum and Bitcoin blockchains as the main public chains. By creating a developer-friendly blockchain underlying platform, these public chains support allowing anyone to build and use decentralized applications running on blockchain technology in the platform, allowing users to create complex operations according to their own wishes. Provides underlying templates for developing dAPPs.

The key to ensuring the stable operation of the public chain lies in a specific consensus mechanism. For example, the Bitcoin blockchain is maintained by the proof-of-work mechanism (PoW), and Ethereum relies on the proof-of-stake mechanism (PoS). They exist as a combination of economic rewards (Tokens) and encrypted digital verification. Further explanation: Token will encourage people to actively participate in the maintenance of nodes and jointly maintain the security of data on the chain, and these maintained blockchains are usually considered "completely decentralized".

So, what are the advantages of public chains? What does it do?

1. Public chains can protect users’ rights and interests from the influence of program developers

In public chains, program developers have no right to interfere with users, so public chains can protect users. User Rights of the Program. In addition, highly decentralized distributed data storage is also one of the biggest features of public chains. The advantages of open and transparent transaction data and the inability to tamper with data enable public chains to effectively protect users' data security.

2． Public chains can produce network effects

An information product has an inherent need for interconnection, because the purpose of people producing and using them is to better collect and exchange information. As the scale of the network expands, users can obtain more value from it and their needs are better met. The shared chain is open, so it has the opportunity to be applied by many external users and produce a certain degree of network effect.

In other words, as the scale of the public chain network expands, the number of users continues to increase, and the network effect continues to increase.

3. Public chains can be applied in actual business scenarios

In addition to financial applications, any application scenario that requires higher trust, security and durability, such as 3.0 era applications such as asset registration, voting, management, and the Internet of Things will be affected by public chains on a large scale.

In short, the underlying public chain is equivalent to the infrastructure of the blockchain world, and solutions are used to expand the performance of the underlying public chain or provide service support for commercial applications. Only when the underlying public chain is solid, stable and efficientOn the basis of its operation, blockchain commercial applications can be developed and implemented. The importance and necessity of the public chain in the entire blockchain field, the development space and demand are very large. However, it still takes some time to correctly distinguish its advantages and problems and to explore application areas in a down-to-earth manner.

6. What is the public chain in the blockchain?

Public chain is also called "public chain", which means that anyone in the world can enter the system to read data at any time. , send a blockchain that can confirm transactions and compete for accounting. 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. In terms of application, public blockchain chains mainly include Bitcoin, Ethereum, Hyperledger, most altcoins, and smart contracts. The ancestor of the public blockchain chain is the Bitcoin blockchain, which has the following characteristics ：

1. The code is open source

The code is uploaded to github, and everyone can download the complete blockchain data and accept the test of the public.

2. Complete decentralization

Anyone can become a node, every node is public, everyone can participate in the calculation of the blockchain, and any node can It is not permanent, but periodic, and no center is mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain, and anyone can participate in the consensus process. The consensus process determines which block can be added to the blockchain, and its exact current state. Everyone can receive financial rewards, proportional to their contribution in the consensus process. These public chains are often considered to be “completely decentralized.”

3. Develop decentralized applications

Program developers can easily develop decentralized applications through this public chain. Public chains can protect users’ rights and interests from the influence of program developers.

7. What are the three major public chains of the blockchain?

The three major public chains of the blockchain refer to BTC, ETH, and ADA
The blockchain public chain is also called the blockchain public chain. The public chain means that anyone can read the data in the system at any time. The public chain is often completely decentralized. This feature allows No one or institution can control or tamper with the data on the chain.
Extended information:
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 "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
Types
1. Public Blockchains
Public Block Chains refer to: Any individual or group in the world canTo send a transaction, and the transaction can obtain valid confirmation from the blockchain, anyone can participate in its consensus process. The public blockchain is the earliest blockchain and the most widely used blockchain. The virtual digital currencies of all major bitcoins series are based on the public blockchain. There is only one blockchain corresponding to this currency in the world. .
2. Consortium (Industry) Blockchains
Industry Blockchains (Consortium Block Chains): Multiple preselected nodes are designated within a certain group as bookkeepers, and each block is generated by all preselected nodes. Nodes jointly decide (pre-selected nodes participate in the consensus process), other access nodes can participate in transactions, but do not participate in the accounting process (it is essentially still managed accounting, but becomes distributed accounting, how many pre-selected nodes, how to decide each The bookkeeper of the block becomes the main risk point of the blockchain), and anyone else can conduct limited queries through the open API of the blockchain.
3. Private Blockchain
Private Block Chains: Only use the general ledger technology of the blockchain for accounting. It can be a company or an individual, and the blockchain can be used exclusively. With write permissions, this chain is not much different from other distributed storage solutions. Traditional finance is trying to experiment with private blockchains, while applications of public blockchains such as Bitcoin have been industrialized, and application products of private blockchains are still being explored.

8. What is the difference between blockchain and public chain, private chain and alliance chain?

Blockchain is strictly defined into three types: public chain, private chain, and alliance chain. The core difference between these three types of blockchains is the degree of openness of access rights, or the degree of decentralization. Generally speaking, the higher the degree of decentralization, trust and security, the lower the transaction efficiency.

In general, each type of blockchain has its own specific model and value. It cannot be said which one is better. As long as whoever solves the needs is valuable.
