ℹ️ Info
🤝 The corresponding xlayer op-reth release is [v1.11.3].
XLayer Reth is a customized implementation of Reth optimized for the XLayer network, an Optimism-based Layer 2 solution.
This project provides a high-performance, production-ready Ethereum execution client tailored for XLayer's specific requirements. It builds upon the upstream Reth codebase with custom optimizations and features for the XLayer network.
This repository provides the exact same functionality as the Reth-based implementation we currently use and will eventually replace the Reth repository.
Breaking Changes
Flashblocks payload protocol upgraded to v2 (PR #176): the builder now emits an explicit sequence_end signal on payload resolution. Note that this is a breaking change and flashblocks-aware RPC nodes must be upgraded together.
Flashblocks RPC revamp
This release includes the full redesign of the X Layer flashblocks RPC layer (#176) which now completely replaces the previous flashblocks RPC design which was based on Optimism's op-reth.
Flashblock reorg protection
Zero-reorg guarantees for flashblocks on the application layer is also now supported with this new release (PR #210) for subscribed flashblocks RPC nodes.
