Celestia: Getting Started with Modular Blockchain

Author: Celestia, translation: Golden Finance xiaozou

Modular blockchains are changing the way we think about and build decentralized applications. Why focus on modular blockchains? Why is it different this time? We could write an entire book on the beauty of modular blockchains, but most people don’t have the time to read them all, so we wrote this short article to describe the benefits of modular blockchains for you. rough outline.

1**, limitations of monomer chains**

Most current blockchains are monolithic chains, so before we explain what modularity means, it is worth understanding monolithic blockchains.

A monolithic blockchain is a general-purpose blockchain that performs all tasks. In fact, the approach of the monomer chain is to “do everything by yourself”.

Among the monolithic blockchains are Solana and Sui.

We must not forget that monomer chains are an important first step. They show us that all kinds of new applications can be built using blockchain. Once people start building and using applications on the monomer chain, they will always encounter difficulties of one kind or another. ‍

· **Development and construction do not follow one’s own will. **Sharing space on someone else’s blockchain limits what you can build for your application.

· **Application costs are high. **Exorbitant fees may creep up and make applications unaffordable.

· NOT OPEN TO ALL. Boost usually means fewer people will be able to check that the network is functioning properly.

Many of these difficulties make monolithic blockchains difficult to use, or simply ignore why we use blockchains in the first place.

**2. What is a modular blockchain? **

In the last few years, a new approach to building blockchains has emerged. This new approach is what people call a “modular blockchain.” But what exactly is a modular blockchain?

Modular blockchains are specialized chains. They only perform one or two tasks - as opposed to monolithic chains.

However, modular blockchains do not operate alone. Multiple modular blockchains come together to perform all the tasks that a monolithic chain can do on its own. This combination of chains is what we call a modular stack.

You can think of modular blockchains as Lego bricks. You can mix and match building blocks to create different structures, and you can mix and match modular blockchains to create different modular stacks.

Among the modular blockchains are blockchains such as Celestia and rollup. rollup hosts applications and does many of the same things as monolithic blockchains. Modular rollups use another blockchain (like Celestia) to do what it doesn’t.

As you can see, modular blockchains are multiple specialized blockchains working together to do all the tasks of a monolithic chain. If there is one thing you must remember about modular blockchains and monomer chains, it is this:

· Single block chain is a universal chain

· Modular blockchains are dedicated chains

**3. Why is modularization an improvement? **

You now know what a modular blockchain is. But how do they improve upon the challenges faced by monolithic blockchains?

· Modular blockchain allows you to create whatever you want

Celestia is really easy and convenient for a reason. Without execution, Celestia has far fewer restrictions on building applications and modular blockchains on top of it. The design space is vast, including everything from novel virtual machines to unique privacy models to novel blockchain architectures. And these are just the surface.

In fact, developers can create anything they want.

· Modular blockchain can make your application cost lower

Of course, we want to allow users to use applications at a low price while creating them freely.

“Data Availability Sampling” is the technique Celestia uses to achieve this. The name might sound confusing. However, this means Celestia can provide applications with greater capacity as more users join the network.

· **Modular blockchain allows you to create open access for all. **

But if people can’t afford to check the chain, then it’s not much different from using a centralized application. This is why it is critical to keep the cost of confirming that the blockchain is functioning properly low.

Modular blockchains use techniques such as data availability sampling and proofs of fraud or validity to achieve this. You’ll come across these terms a lot when you go down the modularity rabbit hole. All you need to know for now is that they can make the cost of the blockchain quite cheap and help people check that the blockchain is working properly.

4 Conclusion

The above is a brief introduction of modular blockchain and monolithic blockchain. Monolithic blockchains were the first to show us the possibility of decentralized applications. Now that we have modular blockchains to take these ideas a step further, let’s continue our love for blockchains.
