Scroll Blockchain: A Beginner's Guide

5 Nov 2023

Scroll is a layer 2 scaling solution to the Ethereum blockchain that utilizes ZK technology, enabling faster and more efficient transactions while maintaining the security of the Ethereum blockchain.
One advantage of Scroll network is that it is more accessible, more responsive, and can support more users at once than Ethereum alone.
In simple terms, is a new technology that makes Ethereum faster and cheaper to use. It does this by bundling transactions together and processing them off-chain. This means that transactions can be processed much faster and for a much lower fee than on the Ethereum mainchain.

How does Scroll work?

To understand how works, it's helpful to first understand how Ethereum works. Ethereum is a blockchain, which is a distributed ledger that records all transactions. When you make a transaction on Ethereum, it is added to a block and then processed by the network. This process can take some time, and the fee for processing a transaction can be quite high. solves this problem by bundling transactions together and processing them off-chain. This means that transactions are not processed by the Ethereum network directly. Instead, they are processed by a group of validators who are responsible for verifying the transactions. Once the transactions are verified, they are added to a block and then submitted to the Ethereum mainchain for finalization.
This process is much faster and cheaper than processing transactions on the Ethereum mainchain. transactions are typically processed in seconds and cost just a few cents in fees.

Here is an analogy that may help you understand how Scroll works:
Imagine that you are at a grocery store and you have a cart full of groceries. You could wait in line to pay for your groceries at the checkout counter. However, this would take some time. Instead, you could use a self-checkout kiosk. This would be much faster and easier. is like a self-checkout kiosk for Ethereum transactions. It allows you to process your transactions off-chain, which is much faster and cheaper than processing them on the Ethereum mainchain.

Why is Scroll important?

There are many benefits to using the blockchain, including:

  • Reduced fees: It significantly reduces the cost of Ethereum transactions. For example, a typical Ethereum transfer can cost around $2-$5 in gas fees, while a transfer can cost as little as a few cents.
  • Increased speed: Transactions are processed much faster than Ethereum mainchain transactions.
  • Improved security: It inherits the security of the Ethereum mainchain. This means that users can be confident that their funds are safe and secure.
  • Access to more dApps: A growing number of dApps are being deployed on, giving users access to a wider range of applications.

Here are some specific examples of how Scroll can be used to improve the user experience of Ethereum:

  • Gaming: It can be used to make Ethereum-based games faster and more affordable to play. For example, It can be used to reduce the cost of gas fees for in-game transactions.
  • Decentralized finance (DeFi): Scroll can be used to make DeFi applications faster and cheaper to use. For example, Scroll can be used to reduce the cost of gas fees for swapping tokens or providing liquidity.
  • Non-fungible tokens (NFTs): It can be used to make NFTs more affordable to buy and sell.

Why Opt for Scroll in Development?

Efficiency: Scroll boosts Ethereum's performance securely. By using ZK Rollups, Scroll enhances Ethereum's blockspace, ensuring security while reducing network congestion. Zero-knowledge proofs verify transactions, allowing Scroll to handle more transactions without compromising decentralization.
