Construction of blockchain main chain

1.

This is two different concepts. According to different standards, blockchain can be classified into three categories:

& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain

 &# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain

 &# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain

the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process

2. Due to the powerful effect of blockchain and many application fields, there are not a few enterprises carrying out the research and development of blockchain technology
according to the latest news, bat and Jingdong have announced the layout of the blockchain field, while Yingtang Zhongchuang, which uses blockchain technology for system development, has already built the blockchain platform internally, which is mainly applied to five scenarios, including finance, Internet of things public services, charity and supply chain. Alibaba's plan is to track the sales path of goods through the blockchain and establish a verification network to prevent counterfeiting. Jingdong applies blockchain to anti-counterfeiting traceability and food safety. In addition, supply chain finance is also an alternative direction.

3. Jinwowo will focus on blockchain technology to promote the legal circulation and commercial application of big data. The following is the development trend of blockchain in 2018 analyzed by jinwowo:
1. Asia and the Middle East will actively promote blockchain
2. Network security requirements will drive the popularization of blockchain
3 - all instries will fully invest in blockchain application technology
4 - automation and privatization are coming.

4. Many virtual currencies, once withdrawn from the exchange, have to be stored in third-party wallets such as imtoken. This is also forced helpless, because there is no own wallet, so can only "rely on others."
How can we live an independent life without looking at others? This will lead to a word: the main chain
the term "main chain" comes from the "main network" (relative to the test network), that is, the officially online and independent blockchain network
at present, among the top 50 blockchain projects in terms of market value, 12 projects are "main chain" (the current data has changed), and Ethereum is the most successful one
Ethereum is a main chain that has its own independent wallet and can "provide housing" for other currencies
next, through the analysis of Ethereum, we will give you an in-depth understanding of what is the main chain
most of the crowdfunding projects in the market are based on Ethereum. You can understand that Ethereum is a computer operating system, similar to the windows system, and the various tokens on Ethereum are equivalent to all kinds of software on our computers. Developers can pay Ethereum to run projects on Ethereum. However, Ethereum is not perfect. The more projects based on Ethereum, the greater the network demand for Ethereum. In serious cases, it will lead to congestion
in fact, most of the main chain projects are still in the stage of technology R & D and improvement, and there is still a long way to go before the real technology is implemented
the most fierce competition in the field of blockchain is actually the battle of "main chain". Whoever can become the main chain of the basic layer of the blockchain is likely to become the future giants such as apple and Microsoft
in addition, in the domestic public chain, the Walton chain is the underlying commercial application public chain, which combines the software level features of blockchain, such as decentralization and unforgivability, with the hardware of RFID chip independently developed, to provide traceability, authentication solutions, and design instry data encryption and distributed storage database building services for all walks of life
of course, it doesn't mean that projects with a main chain are better than projects without a main chain. Some projects, e to their nature, don't need a main chain, such as BNB, whose main purpose is to offset the handling charges in the currency exchange, so it doesn't matter whether there is a main chain
from bitcoin to Ethereum, and now to EOS, many gods are building the main chain, trying to climb the tide of the times. Who will be the future king of blockchain? Let time give us the answer.

5. The main chain is the underlying technology foundation of all blockchain applications, just like chips and operating systems. Whoever can become the main chain of the basic layer of the blockchain and accumulate a large number of users and scenes is likely to become the future giants such as apple and Microsoft
however, for most scenarios of using and developing blockchain, it is not necessary to re create a set of blockchain, as long as we develop our own applications based on the existing underlying blockchain or technical framework. Therefore, for the similar encryption algorithm, P2P technology, consensus algorithm, we only need to have a basic understanding, and do not need in-depth study
the primary goal of blockchain application development is to find a relatively mature underlying blockchain for application development. The underlying blockchain needs powerful and easy-to-use development interface or framework, scalability, transaction frequency, etc
Rong technology is a listed financial technology company, which currently provides main chain construction and development services http://www.erong.com/new/blockchain/backbone/index.html

6. Chongqing jinwowo analysis: it refers to the facilities that provide public services for the development of blockchain technology, instry and application. It is the basis for ensuring the normal progress of blockchain economic and social activities. It is the general condition for the survival and development of blockchain economy.

7. The characteristics of blockchain ensure that the information can not be tampered with and stored in a decentralized way, which can greatly promote data sharing, optimize business processes, rece operating costs, improve collaboration efficiency, and build a trusted system
at present, many local governments in China are promoting blockchain government application platforms, such as Chongqing's blockchain government platform, Guangzhou's tax chain platform, Hunan Changsha's SMIC blockchain public platform, and so on
from the perspective of technical characteristics, value and domestic cases, it is very necessary.

8. Coin circle is the application circle of blockchain in encrypted digital currency. At present, chain circle is the application on the chain, and blockchain system template is chain circle

9. Yuan Li, former vice president of China Development Bank, said that the construction of the platform should have three supports: first, the support of catastrophe swap model; Second, it should be supported by the government's credit; The third is to provide technical support for blockchain. This year, a SMIC blockchain platform project has been set up in Changsha high tech Zone, which aims to integrate public services with blockchain. It is for the majority of enterprise users, and companies interested in participating can go and have a look.
