What is SCR: Understanding Selective Catalytic Reduction Technology in Modern Emission Control Systems

Scroll's Positioning and Significance

In 2023, the Scroll team launched Scroll (SCR), aiming to address scalability issues on the Ethereum network.

As a Layer 2 rollup solution using zero knowledge proof technology, Scroll plays a crucial role in scaling Ethereum and improving its transaction processing capabilities.

As of 2025, Scroll has become an important player in the Ethereum scaling ecosystem, with 174,780 holders and an active developer community. This article will delve into its technical architecture, market performance, and future potential.

Origins and Development History

Birth Background

Scroll was created by the Scroll team in 2023 to solve Ethereum's scalability challenges and high transaction costs.

It was born during the ongoing blockchain technology boom and the increasing demand for more efficient Ethereum scaling solutions, aiming to bring billions of users into the Ethereum ecosystem by providing a secure and efficient Layer 2 network.

Scroll's launch brought new possibilities for Ethereum users and developers seeking faster and cheaper transactions.

Important Milestones

• 2023: Mainnet launch, achieving significant transaction throughput improvements for Ethereum.
• 2024: Major upgrade introducing enhanced zero-knowledge proof technology for better scalability and security.
• 2024: Adoption by various DeFi protocols and dApps, pushing the price to its all-time high of $2.45.
• 2025: Ecosystem expansion, with the number of applications built on Scroll growing significantly.

With support from its community and development team, Scroll continues to optimize its technology, security, and real-world applications.

How Does Scroll Work?

No Central Control

Scroll operates on a decentralized network of computers (nodes) spread across the globe, free from control by banks or governments. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, giving users greater autonomy and improving network resilience.

Blockchain Core

Scroll's blockchain is a public, immutable digital ledger that records every transaction. Transactions are grouped into blocks and linked through cryptographic hashes to form a secure chain. Anyone can view the records, establishing trust without intermediaries. Scroll's zero-knowledge rollup technology further enhances performance and scalability on Ethereum.

Ensuring Fairness

Scroll uses zero-knowledge proof technology to validate transactions and prevent fraudulent activities like double-spending. Validators maintain network security through running nodes and processing transactions, and are rewarded with SCR tokens. Its innovation includes increased transaction throughput and reduced costs on Ethereum.

Secure Transactions

Scroll uses public-private key encryption to protect transactions:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security, while transactions remain pseudonymous. Zero-knowledge proofs provide additional privacy and security features.
