Origin and Development History

Background of Creation

Scroll was created by the Scroll team in 2022, with the goal of solving Ethereum's scalability challenges. It emerged during the ongoing blockchain scaling debate, aiming to bring billions of users into Ethereum's ecosystem by providing a secure and efficient Layer 2 solution.

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

Important Milestones

• 2022: Development and initial testnet launch, showcasing zero knowledge proof technology for Ethereum scaling.
• 2024: Mainnet launch, introducing enhanced throughput and reduced transaction costs for Ethereum users.
• 2024: Price reached an all-time high of $2.45 on October 11, 2024.
• 2025: Ecosystem expansion, with various DApps and protocols adopting Scroll for improved performance.

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

How Does Scroll Work?

Decentralized Control

Scroll operates on a decentralized network of computers (nodes) globally, free from control by any single entity. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, while empowering users with greater autonomy and enhancing 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, forming a secure chain. Anyone can view the records, establishing trust without intermediaries.

Scroll utilizes zero knowledge proof technology to significantly enhance Ethereum's scalability and performance.

Ensuring Fairness

Scroll employs a zero knowledge rollup mechanism to validate transactions and prevent fraudulent activities like double-spending. Participants maintain network security through proof generation and verification, and are rewarded with SCR tokens.

Its innovative approach provides higher transaction throughput and lower costs compared to the Ethereum base layer.

Secure Transactions

Scroll uses public-private key cryptography to secure 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 maintaining pseudonymous transactions. Additionally, Scroll leverages zero knowledge proofs to enhance privacy and scalability.
