CitreaScan

# Overview

CitreaScan - Blockchain Explorer for Citrea Network

# What is CitreaScan?

CitreaScan is the dedicated blockchain explorer for the Citrea Testnet, powered by Blockscout - the leading open-source blockchain explorer. It provides a comprehensive and user-friendly interface for exploring and analyzing the Citrea blockchain.

# What is Citrea?

Citrea is Bitcoin's first ZK Rollup - a groundbreaking layer 2 solution that enhances Bitcoin's capabilities with zero-knowledge technology. As a Type 2 zkEVM (Zero-Knowledge Ethereum Virtual Machine), Citrea processes transactions off-chain and settles them on Bitcoin with cryptographic proofs.

# Key Features of Citrea Network:

  • Bitcoin Settlement: Every transaction is fully secured by zero-knowledge proofs and verified by Bitcoin
  • EVM Compatible: Fully compatible with Ethereum Virtual Machine, enabling EVM developers to build on Bitcoin
  • ZK Technology: Uses zero-knowledge proofs for efficient and secure transaction processing
  • Scalability: Processes numerous zkEVM transaction batches efficiently

# CitreaScan Features
