Network configuration private chain of blockchain

1. At present, there are three application deployment types of blockchain: public chain, private chain and alliance chain. What's the difference between them? What are the typical applications<

public chain: open to all, anyone can participate

private chain: open to indivial indivials or entities

alliance chain: open to specific organizations

2.

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

generally speaking, each type of blockchain has its own specific mode and value, which is better than others. As long as the demand is solved, the blockchain is valuable

3. A protocol is a set of rules for managing a network. Blockchain protocol usually includes rules of consensus, transaction verification and network participation. Agreements often rely on economic incentives - which means they depend on an asset
generally, protocol level assets can also be used as local procts of the protocol (no platform required!) bitcoin is a good example. Bitcoin (capital B) refers to the agreement. The agreement depends on the local asset: bitcoin (small b). This local asset is also used as the end proct: it's the user's means of payment, the store of value, and (to be honest) a degree of hype. Please note that bitcoin does not really provide a platform. It's not very friendly for developers trying to build new procts on it< On the other hand, Ethereum has three levels. It's an agreement that provides the basic rules. This is a platform that enables developers to build new procts on the system. Moreover, because its agreement contains a local asset, it also gets a built-in proct (in the form of ether)
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

4. In the previous news, in the function evaluation, performance evaluation, password evaluation and security evaluation of the "trusted blockchain technology platform" organized by the Institute of information and communication of the Ministry of instry and information technology, the platform of fun chain blockchain has passed all the evaluations, and its comprehensive ability is far ahead.

5. 1. Alliance chain
the openness and decentralization of alliance chain are limited. Its participants are screened out in advance or specified directly. The read permission of the database may be public, or it may be limited to the participants of the system just like the write permission. Currency exchange of digital currency
2. Public chain
public chain is that every node in the blockchain is open, everyone can participate in the calculation of blockchain, and everyone can download complete blockchain data, also known as blockchain ledger
public chain refers to the process that anyone in the world 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 whether a block can be added to the blockchain and the exact current state
3. Private chain
202. What is private chain
private chain refers to the blockchain whose write permission is only in the hands of one organization. Read access is either open to the public or restricted to any extent. Related applications include database management, auditing, and even a company. Although in some cases, we hope it can have public auditability, in many cases, public readability is not necessary. It can be said that each of the three chains has its own advantages.

6. Private blockchain: there is only a limited range of participating nodes, data access and use have strict permission management, write permission is only in the hands of participants, and read permission can be opened to the outside world
community blockchain; It is also called alliance chain, which means that the nodes participating in the blockchain are selected in advance, and there are usually good network connections and other cooperative relationships between the nodes; Community blockchain is a practical application scenario of the combination of blockchain and physical goods, such as Domenech jewelry's Maobei mode
Hello, the differences between the two are as above, for reference only, hope to adopt
