The difference between the main chain and the sidechain in the blockchain

According to the degree of independence of the blockchain network, it is divided into two types: main chain and side chain. The differences between the two are as follows:

1. The main chain refers to the blockchain network that is officially launched and can run independently, and the main chain is also called the main network and the mother chain, which is simply the mother of ten thousand chains, and the chain that can generate the chain is called the mother chain.

2. Compared with the concept of the main chain, as long as the sidechain protocol is adhered to, the blockchain anchored to a node on the main chain can be called a sidechain.

The relationship between the main chain and the side chain is one of mutual cooperation. The main chain is like the larger gear in the bike, it is an independent and autonomous blockchain network that does not need the power of other gears and can turn on its own.

Usually blockchains, especially public chains, have a mainnet and a testnet. Mainnet.

It is a trusted blockchain network recognized by the blockchain community, and its transaction information is recognized by all members. Valid blocks are appended to the mainnet's block ledger after being agreed by the blockchain network.

Middle. What a sidechain is, many people don't understand, this concept comes from Bitcoin.

Community, was raised in December 2013. There are some problems with the mechanism of Bitcoin itself or a certain blockchain itself. However, if you modify it directly on the Bitcoin protocol or chain, it is easy to make mistakes.

And because the block of Bitcoin has been constantly operating, if it is wrong, then the amount of funds involved will be large, which is not allowed.

Sidechains do not refer to a specific blockchain, but to all blockchains that adhere to the sidechain protocol, a term relative to the main chain of Bitcoin.

Usually blockchains, especially public chains, have mainnets and testnets. The mainnet is a trusted blockchain network recognized by the blockchain community, and its transaction information is recognized by all members. Today, Beishu Blockchain will talk to you about the main chain and side chain technology of the blockchain.

Pay attention to the circular belt shell number blockchain, from a white to a god!

Many virtual currencies, once withdrawn from the exchange, have to be stored in third-party wallets such as imtoken. This is also forced to be helpless, because there is no wallet of his own, so he can only "send people under the fence".

So how can you live an independent life without looking at people's eyes? This leads to a word: mainchain.

The term "mainchain" is derived from the "mainnet" (as opposed to the testnet), which is the officially live, independent blockchain network.

At present, 12 of the top 50 blockchain projects by market capitalization are "main chains" (the data is subject to change), and the most successful main chain is Ethereum.

Ethereum is a main chain that has its own independent wallet and can also "provide housing" for other currencies.

Next, we will take you to an in-depth understanding of what the main chain is through the analysis of Ethereum.

Most of the crowdfunding projects on the market are developed based on Ethereum, which you can understand as: Ethereum is a computer operating system, similar to the Windows system, and the various tokens on Ethereum are equivalent to various software on our computers, and developers can pay Ether to run projects on Ethereum. However, Ethereum is not perfect, and the more Ethereum-based projects there are, the greater the demand for Ethereum's network, which can lead to congestion in severe cases.

In fact, most of the main chain projects are still in the stage of technology research and development and improvement, and there is still a distance from the real technology landing.

The most fierce competition in the blockchain field is actually the battle of the "main chain". Whoever can become the main chain of the basic layer of the blockchain has the potential to become the future giants such as Apple and Microsoft.

In addition, under the popularization of science, in the domestic public chain, Walton Chain is the underlying commercial application public chain, which combines the software-level characteristics of the blockchain such as decentralization and non-alteration with the self-developed RFID chip hardware to provide traceability, authentication solutions, and design industry data encryption and distributed storage database construction services for all walks of life.

Of course, it does not mean that a project with a main chain is necessarily better than a project without a main chain, and there are some projects that do not need a main chain due to their nature, such as BNB, whose main purpose is to deduct fees on the Binance exchange, so it doesn't matter if there is a main chain or not.

From Bitcoin to Ethereum, and then to EOS, which is now on the altar, many gods are building the main chain, trying to climb the tide of the times, who will be the future king of the blockchain, let time give us the answer.

The main chain is the premise and foundation for the existence of the sidechain.

A sidechain is an altcoin that is nailed to the Bitcoin blockchain and issued with Bitcoin as a guarantee. For example, if I send 1,000 bitcoins to a block, this block is the starting block of sidechain A, and there are 1,000 sidechain bitcoins on sidechain A that can be used for circulation. But the 1,000 bitcoins on the main chain are locked in that block at the same time, and no one can use them.

In the future, when 100 coins on sidechain A want to exchange 100 coins back for bitcoin and then make a special transaction and send it back to the main chain, then 100 bitcoins will be released from the 1000 locked coins and can be used freely.

This is done because it does not increase the total amount of money, and there is no inflation problem (altcoins are inflation in the cryptocurrency world, so there is very little support from stored value users). One of the original ideas was probably that each country would issue a Bitcoin-backed altcoin with a sidechain for domestic circulation, while Bitcoin would be used for state-to-country settlement.

But this idea led to unnecessary repetition and complexity.

Now, many projects use Bitcoin as the main chain to develop other projects, because the blockchain is open source and relatively reliable. Of course, it is also possible to recreate a chain, such as decent.

The main chain 5c c is in position 3 and there are 2 types.

The main chain 4c c is on the 2nd and 3rd, and there are only these two.
