The #بينانس platform was successful when it chose the #Scroll network as the first project to be listed in pre-market trading, because this project is very different from other projects, and came to provide a set of solutions in the field of blockchain, which is what we will learn about in this article.

Scroll is a scalability solution that processes transactions off the main chain, reducing congestion and making the network faster for users, even during peak periods.

Thanks to zk-rollup technology, Scroll can reduce Ethereum gas fees, making DApps and DeFi services less expensive and accessible to users.

Scroll seamlessly integrates with Ethereum, allowing developers to use their existing tools and smart contracts without having to completely rewrite their code.

If you’ve used Ethereum before, you may have noticed that it can be a bit slow and expensive during times of high demand. As more people use the Ethereum network to use decentralized applications (DApps), the network is likely to become congested, resulting in higher fees and slower transaction speeds. That’s where Scroll comes in.

Scroll is a project designed to make Ethereum faster, cheaper, and more efficient, all without sacrificing the security and decentralization that make Ethereum special. Let’s dive into what Scroll is and its scaling solutions.

Scroll is a layer 2 scaling solution designed specifically for Ethereum. In simple terms, it’s a technology that runs on top of the Ethereum mainnet (layer 1) to make things run more smoothly. A key component of Scroll is a cryptographic technology called zero-knowledge rollups (zk-rollups), which is a game changer for speeding up transactions while keeping them secure.

With Scroll, transactions are processed outside of the Ethereum main chain, which helps avoid congestion. Important data is then sent back to Ethereum Layer 1 to make sure everything is in order. This means you can still use all the cool dApps and tools on Ethereum, but without paying high fees or waiting long hours for confirmations.

Why does Ethereum need Scroll?

We can think of Ethereum as a busy highway. When too many people try to use it at once, it slows down, and the cost of using it (gas fees) goes up. And as we all know, no one likes paying high fees, especially when you’re just trying to send some crypto to a friend or use a decentralized application.

Ethereum developers are working hard to find solutions to fix this problem, but the network’s focus on security and decentralization makes it difficult to scale. That’s where layer 2 solutions like Scroll come in — they help take some of the burden off the main Ethereum network while keeping it secure and decentralized.

How does Scroll work?

Assemblies Basics

As we learned, rollups are a clever way to process a batch of transactions outside of the Ethereum mainnet (off-chain) and then send a summary of those transactions back to layer 1 for approval. You can think of it as sending a mass text message to save time instead of sending messages to people one by one.

There are two types of rollups: optimistic rollups and zk-rollups. Scroll uses zk-rollups, which come with additional security. These rollups use what are called zero-knowledge proofs (ZKP) to ensure that off-chain transactions are processed correctly. This way, Ethereum doesn’t have to verify everything twice, making the whole process much faster and cheaper.

Three-layer scroll structure

The Scroll system consists of three main parts:

Settlement Layer: This is Ethereum itself. Scroll uses Ethereum’s layer 1 for things like data availability and zk-rollup proof verification. Essentially, Ethereum acts as the final arbiter, confirming that everything is legitimate.

Chaining Layer: Here, Scroll processes and organizes transactions. This layer groups transactions into batches and sends the information back to Ethereum for safekeeping and verification.

Proof Layer: This is where the magic of zk-rollups happens. A group of computers (called proof machines) work together to generate zero-knowledge proofs that show that transactions were processed correctly. This layer ensures that everything is secure and ready for Ethereum approval.

Zero-Knowledge Virtual Machine (zkEVM)

One of the coolest parts of Scroll is the zkEVM (short for zero-knowledge virtual machine). This sounds complicated, but it basically means that Scroll can run Ethereum-like transactions using zk-rollups without changing how Ethereum works. Developers don’t have to rewrite their code or create new tools to work with Scroll, which is a huge advantage.

zkEVM allows Scroll to remain 100% compatible with Ethereum, making it easier for developers to take their decentralized applications and port them to this faster and more efficient system.

Closing thoughts

Scroll (SCR) is an innovative layer 2 scaling solution that addresses Ethereum’s scalability challenges by leveraging zero-knowledge assemblies. By improving transaction throughput, reducing costs, and maintaining compatibility with the Ethereum ecosystem, Scroll makes it easier and cheaper for users and developers to interact with the Ethereum blockchain.

As Ethereum continues to grow, projects like Scroll will be crucial in ensuring the network can handle the increasing demand for decentralized applications and services.
