How Does Scroll Work?

Decentralized Control

Scroll operates on a decentralized network of computers (nodes) worldwide, free from control by a single entity. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, thus empowering users 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 via 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 compatibility.

Ensuring Fairness

Scroll employs a consensus mechanism to validate transactions and prevent fraudulent activities like double-spending. Participants maintain network security through various activities and are rewarded with SCR tokens.

Its innovation lies in providing a more scalable and efficient Layer 2 solution for Ethereum.

Secure Transactions

Scroll uses public-private key encryption 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 transaction privacy. As a Layer 2 solution, Scroll inherits many of Ethereum's security features while improving scalability.

Scroll's Market Performance

Circulation Overview

As of November 19, 2025, Scroll's circulating supply is 190,000,000 tokens, with a total supply of 1,000,000,000 tokens.
