Origins and Development History

Birth Background

Scroll was created with the mission to become the most secure and trusted Layer 2 network, capable of processing trillions of dollars on-chain and serving as the default place for new innovations in the Ethereum ecosystem. It emerged during a period of increasing demand for scalable blockchain solutions, particularly for Ethereum.

The launch of Scroll brought new possibilities for developers and users seeking high-performance, low-cost transactions on Ethereum without compromising security or decentralization.

Important Milestones

• 2024: Mainnet launch, achieving significant scalability improvements for Ethereum transactions.
• October 11, 2024: Scroll reached its all-time high price of $2.45.
• 2025: Continued development and optimization of zero-knowledge proof technology for enhanced scalability and security.

Supported by its dedicated team and growing community, Scroll continues to refine its technology, security, and real-world applications within the Ethereum ecosystem.

How Does Scroll Work?

Decentralized Control

Scroll operates on a network of decentralized computers (nodes) globally, free from control by any single entity. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, thus empowering users with greater autonomy and enhancing network resilience.

Blockchain Core

Scroll's blockchain serves as a public, immutable digital ledger recording all transactions. 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 enhance performance and scalability while maintaining Ethereum's security guarantees.

Ensuring Fairness

Scroll employs a zero-knowledge rollup mechanism to validate transactions and prevent fraudulent activities such as double-spending. Participants maintain network security through the generation and verification of zero-knowledge proofs, receiving rewards for their contributions.

Scroll's innovation lies in its ability to significantly increase transaction throughput and reduce costs for Ethereum users while preserving the base layer's security.

Secure Transactions

Scroll leverages public-private key encryption to secure transactions:

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

This mechanism ensures fund security while maintaining transaction privacy. Additionally, Scroll benefits from Ethereum's robust security model while offering improved scalability through its Layer 2 solution.

FAQ

What does SCR stand for?

SCR stands for Selective Catalytic Reduction, a technology used in diesel engines to reduce emissions.

What is meant by SCR?

SCR stands for Silicon-Controlled Rectifier, a semiconductor device that conducts current when triggered by a gate signal. It remains on until the current stops.

What is SCR in medical terms?

SCR stands for Serum Creatinine, a blood test used to assess kidney function. It measures creatinine levels, with elevated levels indicating potential kidney issues.

What is the working principle of SCR?

SCR operates by controlling current flow through gate-triggered voltage. It remains off until a sufficient gate signal is applied, then conducts until current drops below the holding level.
