Scroll is a Layer 2 blockchain built on zkEVM Equivalence, launched in early 2021. It is fully compatible with the Ethereum Virtual Machine (EVM), providing a seamless environment for developers to deploy and migrate DApps between Layer 1 and Layer 2 networks without extensive code changes.

Current Zk-Rollup solutions focus heavily on specific applications, making it difficult for developers to standardize code and migrate DApps across different layers. Scroll addresses these issues by implementing zkEVM, enhancing composability and allowing developers to easily transfer Ethereum-based DApps to the zk-Rollup chain with minimal modifications.

Scroll’s structure consists of three key components:

1. Scroll Node:

   • Responsible for transmitting transactions from Layer 2 (L2) to Layer 1 (L1).

2. Roller Network:

   • Generates valid zkEVM proofs to ensure transactions are executed correctly.

3. Rollup and Bridge Contracts:

   • These provide data for transactions, verify the validity of zkEVM proofs, and enable asset transfers between Ethereum and Scroll.

The network processes information by sequencing blocks on L2, which are then submitted to smart contracts on Ethereum for verification. Once validated, the transactions go through phases like Precommitted, Committed, and Finalized before being added to the blockchain.

1. EVM-Equivalence:

   • Scroll functions similarly to other EVM-compatible virtual machines, making it easy for developers to move DApps across different layers without modifying code. This reduces development time and allows teams to focus on building new features.

2. Scalability:

   • Transactions are processed off-chain, with condensed proofs posted on-chain, increasing throughput and lowering costs compared to transactions directly on Ethereum.

3. Security:

   • Scroll undergoes multiple audits from third-party organizations to ensure security. The platform emphasizes transparency and decentralization in its development process, building trust with the community.

Since the launch of its pre-Alpha testnet, Scroll has achieved:

• 397,000+ wallet addresses involved.

• 6,300+ smart contracts deployed.

• 600+ tokens minted.

• An average volume of 32,000 transactions per day.

Scroll offers EVM-equivalent zk-Rollup technology that simplifies DApp development and migration while enhancing scalability, security, and decentralization. Its compatibility with Ethereum, cost-effective transactions, and growing adoption position it as a robust Layer 2 solution for developers and users alike.
