What is the main chain of virtual currency

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. Of course, the central bank will also issue virtual currency. At present, it is suggested to do international work. For example: DGC.. Differentiable

3. Virtual currency refers to the currency that does not exist in reality and exists in a virtual state, such as bitcoin, lightcoin, Ethereum and so on; Token refers to the form of money that can be used as a monetary function and can be used to purchase goods
virtual currency can be used for shopping transactions in certain situations, such as in some places abroad; At this time, it counts as a token and plays the role of currency
but token, such as the shopping card voucher printed by the company itself, can be used for the internal consumption of the company. To some extent, it is equivalent to token; However, it is not a virtual currency
that is to say, virtual currency may be token; But token is not necessarily a virtual currency.

4. Connecting with the wallet on the first floor is equivalent to calling LTC to him. It's really bad. It's a cheat for novices
please accept if you are satisfied

5. In the Internet did not search the gold net, only found the Chinese gold net
China Gold Coin Corporation, established in 1987, is an enterprise directly under the people's Bank of China. It performs the function of selling precious metal currency. It not only shoulders the task of maintaining and increasing the value of state-owned assets, but also bears the responsibilities of the central bank's credibility, social responsibility and inheriting China's long-standing coin culture
if there is a digital currency trading platform, the rules for launching the platform are made by themselves. This platform is not well-known and has never been heard of in the circle. There are still some well-known digital currency projects in China, such as Ruitai coin, Qianjin card, Weimeng coin, and Weitou movie coin. Now, there are more equity crowdfunding projects using digital currency.

6. 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.

7. I'll give you a connection. See for yourself

8. It can be understood as a formal and independent blockchain network; The side chain is not. It does not specifically refer to a blockchain, but is a general term for all blockchains that comply with the side chain protocol.

9.

Main chain: an independent blockchain network officially launched. It can be said that the entity of blockchain storing data is generally considered to be the main chain network itself. For example, BTC main network, ETH main network and EOS main network are main chains

side chain: first of all, the essence of side chain protocol is a cross block chain solution. In short, through this scheme, data information can be transferred between two blockchains. The original proposal of side chain is based on the transfer of bitcoin and other digital assets among multiple blockchains

generally speaking, the side chain is like a channel, connecting different blockchains together to realize the expansion of blockchain. The side chain is completely independent of the main chain, but the two books can "operate with each other" to achieve interaction

side chain protocol - side chain protocol refers to (take bitcoin as an example): it can safely transfer bitcoin from the main bitcoin chain to other blockchains, and also can safely return to the main bitcoin chain from other blockchains. The same is true here for bitcoin to Ethernet or other blockchains. Then, why do we need side chain, or what are the advantages of side chain

the function that the main chain lacks is provided by the side chain

for example, bitcoin network does not have the function of smart contract, but it can achieve this function through the side chain

if the operation efficiency of the main chain is low, some functions of the main chain can be transferred to the side chain

for example, the transfer speed of the main chain is very slow, and there is no way to meet the daily payment needs. We can develop the lightning network as the side chain to meet the daily payment needs. Also because of low performance, Ethereum can not support large commercial DAPP (decentralized application), which can be realized through side chain development

if we put aside the technical rigor, we can use another simpler way to understand the side chain. All the networks that provide support or services for the original primary network can be called side chain, regardless of whether the side chain adopts blockchain technology. For example, the

third party payment network (Alipay / WeChat) can imagine the banking network as the main chain while the third party payment is a side chain.

for cryptocurrency trading, the free network such as bitcoin and other virtual currencies can be regarded as the main chain, and the exchange can be regarded as a side chain

RSK and loom are separately developed side chains for bitcoin and Ethereum main chain

in the first application, both the main chain and the side chain are centralized

in the second application, the main chain is decentralized and the side chain is centralized

in the third application, the main chain is decentralized and the side chain is also decentralized. With the deepening of blockchain technology, we can see the value exchange activities of human beings, It will graally transition from the first application to the third application

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system
