Overview

This section offers a comprehensive overview of Validum Network technology, covering its foundational concepts and key components.

Introduction

Validium Network is an advanced scaling solution designed to optimize blockchain efficiency by utilizing off-chain data storage, significantly reducing energy consumption and transaction costs. By leveraging Zero-Knowledge Proofs (ZKPs) in a scalable, secure manner, Validium enhances the throughput and scalability of blockchain applications while maintaining the integrity and security of on-chain data. Validium Network is leveraging ZKSync technology within its development environment (devnet) to enhance scalability and security.

Zero-Knowledge Rollups

Zero-knowledge rollups, or ZK Rollups, leverage advanced cryptographic techniques known as zero-knowledge proofs. These proofs ensure that each transaction within the rollup is executed correctly without revealing any transaction details. ZK Rollups aggregate (or roll up) transaction data and submit it to a primary chain, such as Ethereum, for final validation.

zkEVM: Enhancing Ethereum Compatibility

At the core of the Validium Network is the zkEVM, which is designed to execute transactions while maintaining full compatibility with Ethereum. This compatibility allows seamless integration and interaction with the broader Ethereum ecosystem.

Verification by External Validators

One of the key advantages of ZK Rollups is their verifiability by external validators. Unlike traditional blockchains that require running a full node to verify transactions, ZK Rollups allow their state to be validated externally through the proof provided. This makes it simpler and more efficient to ensure the integrity of the rollup.

Elastic Chain: A Network of ZK Chain Rollups

ZK Rollups can also be validated by other rollups, facilitating the creation of a trustless network of rollups known as the elastic chain. This interconnected network enhances the scalability and interoperability of blockchain systems.
