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
