Scroll is a Layer 2 solution designed to make Ethereum's blockchain faster and cheaper. It uses zkEVM (Zero-Knowledge Ethereum Virtual Machine) to process transactions more efficiently.
What is Scroll
Here's how it works:
- Transaction Submission: Users send their transactions to Scroll, which interacts with Ethereum's smart contracts.
- Off-Chain Processing: Scroll processes these transactions off-chain (not directly on Ethereum) using zkEVM. This makes things faster and uses less resources.
- Generating Proofs: As it processes transactions, Scroll creates special proofs (zk-proofs) to show the transactions are valid.
- Updating Ethereum: These proofs and the results of the transactions are then sent back to Ethereum's network.
- Verification and Finality: Ethereum checks these proofs and updates, making sure everything's correct. Once verified, these changes are final on the Ethereum blockchain.
In summary, Scroll's goal is to solve Ethereum's issues with slow speeds and high costs, making it easier and cheaper to use Ethereum for apps and transactions.

Pros
Scalability
Scroll boosts Ethereum's scalability by handling transactions off-chain. This reduces network congestion and allows for more transactions, which is great for beginners looking for faster and smoother experiences.
Lower Fees
Users pay less in gas fees on Scroll, as it cuts down on-chain computation costs. This is a big plus for newcomers who are conscious about transaction costs.
Quick Transactions
Scroll's off-chain processing means transactions confirm almost instantly. This fast pace enhances the experience, making it more appealing for those new to crypto.
Cons
zkEVM Node Trust
Users have to trust the zkEVM node's accuracy and security. If there are problems with the node, it might raise concerns for users, especially those new to the technology.
Depends on Ethereum
Scroll relies on the Ethereum mainnet. Any issues on Ethereum, like congestion, could affect Scroll's performance.
Smart Contract Limits
Scroll may restrict how complex or functional smart contracts can be. This might be a downside for users wanting to explore more advanced features.
