# X Layer Overview

> X Layer data on Dune

## What is X Layer?

X Layer is an Ethereum Layer 2 (L2) network, built by OKX on an enhanced Optimism Stack, designed to provide developers with a superior environment for scaling applications. It uses an optimistic rollup architecture where transactions are considered valid by default, with a 7-day challenge period for fraud proofs.

## Key Features and Advantages

### Full EVM Equivalence

* Deploy existing Ethereum applications without any code modifications
* Complete compatibility with standard Ethereum development tools
* Seamless migration from Ethereum mainnet

### Exceptional Performance

* Support for up to 5,000 transactions per second (TPS)
* Negligible gas fees for cost-effective transactions
* 1-second block times for fast execution
* Immediate transaction finality on L2 for most operations

### Battle-Tested Security

* Leverages robust optimistic rollup architecture
* Inherits security guarantees of Ethereum
* Cryptographic fraud proofs when needed
* All L2 data published to L1, ensuring trustless and censorship-resistant operation

### Enterprise-Grade Reliability

* Conductor high-availability cluster ensures sequencer redundancy
* 99.9% uptime for production-ready dApps
* Continuous synchronization between L2 and L1

### Network Specifications

* **Technology Stack**: Enhanced OP Stack
* **Gas Token**: OKB
* **Network Type**: EVM-compatible Layer 2
* **Base Chain**: Ethereum
* **Consensus**: Optimistic Rollup with 7-day challenge period

### Architecture Components

* **Virtual Machine**: EVM-equivalent
* **Sequencer**: Trusted (op-node in sequencer mode with op-geth via Engine API)
* **Bridge Service**: Monitors and syncs L1/L2 contract events
* **AggLayer Integration**: ZK proof generation for cross-chain settlement
