This article talks about the important infrastructures in the era of Metaverse and the Web3: Rollup, Polkadot, Cosmos, etc.

Since the end of August, the public chain market has continued to be hot and has attracted a lot of attention. In addition, the Cosmos ecosystem on the multi-chain side has made continuous progress, and the Polkadot slot auction has also begun.

In this issue, we will talk about the current models of multi-chain. There is a high probability that future multi-chain scenarios will basically focus on these three models. In this article, we will combine the side chain and Rollup on the ETH single chain, using a village and bazaar. Metaphor , tell everyone the difference between them.

Will the application chain be in charge in the future?

Let me talk about the premise first, that is, whether the blockchain world in the next three to five years will be an era in which Appchain (application chain) is dominant.

Not to mention that AXIE is powerful. Although Cosmos has established a model of a multi-chain world for everyone before, most of everyone’s understanding of blockchain DAPP is still focused on “one or more smart contracts on a certain chain.” This chain can be ETH, BSC, or SOL…

Until the popularity of the Ronin sidechain, everyone discovered that a blockchain project can be realized through a single Appchain.

Someone asked, Appchain and like Ethernet Square Layer1 public chains such difference in what?

Simply put, the Layer1 public chain is like Taobao , and all merchants can go up and open an online store. Safe and convenient, but the customization is also limited to those options provided by Taobao.

The application chain is like a company’s own official website . How you want to build this website is up to you, from server architecture to front-end web page design to back-end database selection, but it can only serve your own company. .

Looking at the current Internet era, Taobao online stores coexist with separate corporate websites. It is not difficult to deduce that the future blockchain world must also be a world where Dapp and Appchain coexist.

Then through a simple analogy, let’s take a look at the comparison of various models in the future multi-chain universe, but please note that this is only from the perspective of security, but it can also be said to be the most important perspective.

After all, blockchain solves the problem of trust, and to trust, you must first be safe. The models we are going to talk about today are: single chain (side chain and Rollup), multi chain (non-shared security, slot-type shared security, rental-type shared security).

Single chain: side chain and Rollup

First of all, let’s make two pre-existing analogies. ETH is a fully functional village with security guards; Dapp is a certain facility in the village, such as a market, a tavern, a farm…

  • Starting from this analogy, let’s take a look at what side chains (such as Matic ) are.

Obviously, the side chain is another village that is very similar to ETH, which is also fully functional. There are also bazaars, taverns, farms…and a main road leading to the ETH village.

So what’s the difference? There are too many people in the ETH village, and the place is small. When you go to the market to buy a dish or go to a tavern for a drink, you often have to line up, not only in line, but also expensive. The village on the side chain has a small population and a large land. Basically, there is no need to queue for anything. The prices are still cheap, which sounds like a paradise.

However, the ETH village has a strong security force, security is everywhere, and everyone has a “pistol” in their hands. More importantly, these security guards have passed the test of time. Each character is upright, and there is almost no practice of favoritism. Living and working in the ETH Village, you can put your heart in your stomach and feel full of security.

The security of the side chain village is of course not as good as that of the ETH village. Specifically, the security guards hired by the side chain village are somewhat inferior to ETH in terms of equipment and level. Besides, it has not been tested by time, so I don’t know the character. . So when you produce and live in the side chain village, although the experience is better, the sense of security is really not as good as the ETH village.

  • Rollup

Recently, several Rollup villages have been newly built next to the ETH village. They are very similar to the side chain village, but they are a bit different from the side chain village.

They did not hire security guards in their villages, but they hired security guards from the ETH village to patrol regularly. Therefore, in these villages, the sense of security is almost the same as that of the ETH village, and the cost of living is significantly lower than that of the ETH village, and only slightly higher than the side chain village , so Many businessmen said that when Rollup Village is repaired, they will move the shop or open a branch in Rollup Village.

  • Appchain

Appchain like Ronin, this is a village with a single function. For example, it can only make wine and cannot do other things. The security here is the same as the side chain village. They are hired by themselves, but because the function is very single, the security is not First and foremost, making wineries cheaper and more efficient in wine production is what the villagers are most concerned about.

Multi-chain universe: Cosmos, Polkadot

After talking about the single chain, let’s take a look at the multi-chain universe.

  • Cosmos (non-shared security)

Cosmos is a huge village, but there are basically no shops in it, only roads and architectural styles (Cosmos SDK). It defines how wide the road is to build a village, and what materials are used to build the house. It also provides detailed drawings to encourage everyone to go out and build more villages, as long as the road is completed and a road is built back to Cosmos.

So the villages around Cosmos built with Cosmos Village drawings have everything. The only thing in common is that they all have a way back to Cosmos Village, so they can also walk each other.

The Cosmos Village is guarded and well equipped. The villages around Cosmos built with drawings also have security guards, but they are all hired at different levels.

This has also led to relatively good public security in some villages, and poor public security in some villages. The advantage is that the cost of living in most villages is not high. The disadvantage is that in some villages with poor security, some “unlawful businessmen” may sneak into those villages with better security and be kidnapped, which is considered a safety hazard.

  • Polkadot (auction-style shared security)

Polkadot is also a huge village, there are no shops, only roads and building samples (Substrate), as well as security. Dot also defines how wide the road is to build a village, what materials are used to build the house, and provides detailed drawings to encourage everyone to go out and build more villages. As long as the road is completed and a road is built, it will be done back to Dot.

But unlike the almost unlimited roads in Cosmos Village, the roads that Poka Village can lead to the outside are limited. This also determines that those who want to build villages around Bokarna must compete for the limited number of roads in Bokarna, which is also commonly known as the “slot auction.”

To win the slot auction, the economic strength of the village must be strong. After all, the auction is all about money. The advantage is that as long as you win the auction and there is a way to Polkadot, then in addition to enjoying the convenient communication with other Polkadot connected villages, you also have a big advantage, without worrying about safety issues.

Because Polka Village will send its own super security guards to every village that wins the slot auction and has a road connection with Polka Village. None of these villages need to find their own security guards, and the village of Poka has completed the security work.

Polkadot’s village building templates and drawings are intuitive and easy to use, and quickly become the first choice for all tribes who want to build a village. However, they face a problem. Many small tribes have no money and are unlikely to win the slot auction. Their villages can be built, but without the security of Poka Village, the safety and public order of many villages will be a big problem.

So a satellite village (Octopus Village) in Near Village discovered this business opportunity and provided these small tribes with a new option, which is to provide a road access plan similar to Poka Village. All Napoca Village drawings built Every village can build a road to Octopus Village , because Octopus Village is also a road interface designed according to Boca’s drawings.

This is to distinguish octopus village and the village of Boca district, Boca access to the village there are generally strong economic strength of large tribe, but because of the need to pay a high cost for the security of Boca village, it is usually Access wave The villages in Ka Village are mainly integrated villages , with multiple facilities, such as platform-type Acala, Moonbeam… The security costs of multiple facilities are shared, which is relatively economically reasonable.

The octopus villages are usually small tribes with average economic strength, and they are usually only responsible for one type of facility, such as planting or wine making, which is the Appchain we mentioned earlier, but at least, this gives these people want to use it. The architectural drawings of Boca Village, which could not win the auction and needed a certain degree of security, provided a shelter.

These are probably the three models of multi-chain currently appearing. In the multi-chain universe of the Web3 era, which form do you prefer? Welcome to share your views in the message area.
