This article discusses the Metaverse and the fundamentals of the Web3 era: Polkadot, Rollup, Cosmos.

Since the end of August, the public channel industry has received a lot of attention. Additionally, the Cosmos ecosystem in many channels has continued to improve, and the Polkadot competition has also started.

In this case, we will discuss the current multi-chain model, the future multi-chain will mainly focus on most of our models, in this article we will provide the components and aggregates in ETH. . The example of using a chain, a village and a market shows everyone the difference.

Will app chains hold power in the future?

First, let's talk about where the global blockchain in 3-5 years will be where AppChain (application for adoption) will last.

Not to mention that AXIE is amazing, although Cosmos is designed for multiple global chains, most understandings of blockchain DAPPs still focus on "one or more special chain smart contracts". This chain can be: ETH, BSC, SOL…

Until the Ronin sidechain became popular, we learned that anyone could use an AppChain blockchain project separately.

Some people ask what is the difference between AppChain and public Set 1 chains like Ethereum.

Stopped,Layer1 public channel like Taobao., any seller can open an online store. It is safe and convenient, but the ability to adjust is also limited to the options offered by Taobao.

andThe risk is the same as on the company's official website.How you build this website is up to you, from server architecture to front-end website design to data fetching options, but you can work in your own business.

Looking at the current situation on the Internet, it is not difficult to determine whether the Taobao online store is integrated with web sharing, and the future blockchain world should be a world where dapps and application chains coexist.

Next, through a simple comparison, we will look at the comparison of different models in various global connections of the future, but please note that only taking care of safety and can be said to be the most important. see. .

After all, blockchain solves the problem of trust and first requires security to be reliable.The models we will be talking about today are:Single chain (side chain and wrap), multi-chain (no split safety, split joint safety, rental joint safety).

Single Chain: Sidechains and Rollups

To start with two comparisons as an example: ETH is a city that works well with agents and Dapp is a city that specializes in shops, taverns, farms...

1. What is sidechaining (e.g. Matic)

Obviously, the sidechain is another city like ETH. It is also fully functioning and has businesses, taverns, farms, and highways for ETH villages.

So what's the difference? The city of ETH is crowded and places are limited, so if you go to the store to buy groceries or drinks, you will have to wait in line to get to the market. Also the cost is very expensive. Sidechain towns have fewer people and more land, so you don't have to queue for anything, and prices are always cheap, so it sounds like heaven.

However, the ETH security forces were strong, had guards everywhere, and they all had "guns" in their hands.More importantly, these guardians have stood the test of time, honestly, and rarely broken the law for personal gain. It gets into your stomach and you feel comfortable.

The security of the local sidechain is never the same as the ETH villages, especially the agents hired by the local sidechain themselves are slightly inferior to the ETH and do not pass the test of time, so I don't don't know what their attitude is. is like. So the experience is better when you live and work in a sidechain city, but it's not as safe as the ETH city.

2, category

Recently, several new towns have been created alongside ETH villages, which are similar to sidechain villages but slightly different from sidechain villages.

They don't hire a local security guard, but they hire a local ETH supervisor to look after them regularly, so in this villageThe security is almost the same as at ETH Village and the cost of living is lower at ETH Village.Because it is slightly higher than Sidechain Village, many retailers say they will move there or open a branch in Rollup Village during its renovation.

3. Application chain

AppChain like Ronin is a city with a plan. For example, you can only make wine, nothing more. The security here is the same as the local sidechain. The first step is to make the brewery cheaper,The high level of interest in winemaking is of particular concern to the community.

Multi-Channel Universe: Cosmos, Polkadot

Having talked about single strings, let's look at the world of multiple strings.

1. Cosmos (non-shared security)

Cosmos is a big city, but there are no shops, only streets and architecture (Cosmos SDK). You define yourself to design the city, the width of the street, the materials you will use to build the house and the detailed drawings.Everyone is encouraged to go out and build as many villages as possible to complete and return to the Cosmos.

So the villages around Cosmos, made with the Cosmos Village plan, have everything to do, unless they all go back to Cosmos Village, so you can walk on a single muscle.

The Cosmos Village has been well preserved. There are guards in the villages around the Cosmos who look after the paintings, but they are all hired at their own rates and the levels vary.

It also contributes to the fact that some towns are safe and others poor, which has a positive effect on the cost of living in many villages. The downside is that in some dangerous cities, "illegal traders" can be robbed by safer cities. It's a security risk.

2. Peas (safety in competitive mode)

Polkadot is also a big city, with no shops, only roads, design (substrates) and security. The point also means how to build a village, the width of the road and what materials to build a house. They provided detailed artwork and encouraged everyone to go out and build as many cities as possible. And back to Dot.

However, unlike the almost endless roads of Cosmos Village, the exit from Boca Village is restricted. It also determined that they would have to compete for certain roads in Polkadot if they wanted to build a village around Polkadot.This is also commonly referred to as a "slot auction".

The city that wants to win racing bets must have good business, but racing is money in the end. Better if you win the race and only have access to Polka Dot, you will not only enjoy the convenience of connecting to other Polka Dot cities, but also the positive and worry-free benefits. security issues.

Indeed, Polka Village will win the game competition and provide its own super-security to each village connected to the Polka Village road.These cities don't have to take care of themselves and Boca City took care of them.

Because Polkadot city designs and drawings are simple and easy to use, they have become the top choice for any group looking to design a city. However, they face many problems, the small groups have no money and do not seem to win the game, their village can produce, but without the security of the villages of Boca, the safety and security of many cities will be major. Problems ..

As a result, the Octopus Village community is finding this market opportunity and providing new options for these small groups.This provided a similar entry plan to Boca Town, and each town developed with the Boca Town Plan would establish a route to Octopus Village.Because Octopus Village is also a crossroads designed on the scheme of the Polkadot side.

This is also the difference between Octopus Village and Boca Village. People related to Boca Village are usually large and strong families, but they have to pay a high price for the security of Boca Village.Thus, in general, the villages connected to the villages of Boca are more spacious.There are many platform type sites like Akala and Moonbeam... It's also commercially viable as many sites share security costs.

Visitors to Octopus Village are usually small groups with a strong core activity, usually responsible for only one type of facility, like the one above or winemaking, but at least that includes: The Art of Boca City, who didn't win the race, and small local groups need some weather to have a place to live.

This is probably the current Web3 era multi-string, multi-global string,What do you like about it? We invite you to share your thoughts in the linguistic field.
