What does the main chain in blockchain mean

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. Generally speaking, the main chain can be understood as a formal online 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
the purpose of the side chain is to achieve two-way anchoring, so that some cryptocurrency can be "transferred" between the main chain and the side chain. Take bitcoin as an example: through the side chain technology, bitcoin can be "transferred" from the main chain to other blockchains, and can be used on the "transferred" blockchain. At the same time, bitcoin can safely "return" to the main chain; Bitcoin keeps the same value throughout the process. Therefore, the concept of side chain is relative to the main chain; As long as it conforms to the side chain protocol, all existing blockchains, such as Ethereum, lightcoin, zcash, etc., can become side chains
the deployment of side chain technology on the main chain means that users can use their existing assets to access the new cryptocurrency system, so as to achieve the operation purpose that cannot be achieved on the main chain. For example, using rootstock technology will enable bitcoin to conct more complex transaction operations, such as micro payment, through smart contract technology. At the same time, cryptocurrency can also expand its application scope through two-way circulation in the main chain and side chain
on the other hand, because the side chain is an independent blockchain and has its own node network, the code and data are relatively independent; So it will not increase the burden of the main chain in the process of running, to avoid the situation of excessive data expansion. However, the side chain technology is more complex, and it needs to support scripts that can be later reorganized to prove failed transactions and enough running nodes to ensure its security.

3. The side chain is another blockchain outside the main chain, which anchors a node in the main chain, maintains the authenticity of the side chain through the computing power on the main chain, and realizes the transfer of the value on the public blockchain and the value on other account books in multiple blockchains. The most representative implementation is blocksteam. In this kind of blockchain architecture, the main chain is sometimes called parent chain

4. 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.

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

6. 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.

7. 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
it's said that the main chain of Jinyou chain is half finished. At least the direction of blockchain technology is right. Next, we'll wait for them to use the main chain to see the effect on the game platform
I'm still optimistic
