X Layer’s Ethereum Layer 2 Design and OKB Gas Model

Summary

This overview describes X Layer as an Ethereum-compatible Layer 2 built with Polygon CDK and integrated with OKX Wallet, Exchange, and Pay. It explains the network’s Pessimistic Proof upgrade as a design in which transactions are processed on X Layer while proofs and data support verification, including in disputes or withdrawals to Ethereum. The article reports throughput of 5,000 transactions per second, 400 ms block times, and very low fees after the upgrade, but does not provide measurement methods or independent performance evidence.

The network uses OKB as its sole gas token, and the article connects this choice to simpler wallet use and OKX’s exchange and payment services. It also describes plans around DeFi, payments, and tokenized real-world assets, plus ecosystem funding and a transition away from OKTChain. These details are presented mainly as a project and ecosystem overview, with promotional comparisons to other Layer 2 networks. The text does not assess bridge, proof-system, concentration, or token-price risks, so its technical and economic claims should be read as reported project claims rather than independent analysis.

Key ideas

• X Layer is described as an Ethereum-compatible Layer 2 built with Polygon CDK.
• The Pessimistic Proof design processes activity on X Layer and supports verification for disputes or withdrawals.
• The article reports 5,000 transactions per second and 400 ms block times after an upgrade, without supplying independent benchmarks.
• OKB is the network’s sole gas token and is integrated with OKX products.
• The project’s stated focus includes DeFi, payments, and real-world asset tokenization.
