BNB Chain refines its execution client support, phasing out Erigon by December 2025, while introducing Reth for enhanced performance.
BNB Chain has announced a significant update to its execution client support strategy, aiming to enhance performance and stability across its network. This development is part of a broader effort to refine the client ecosystem, ensuring it meets the long-term needs of the blockchain community, according to BNB Chain.
Erigon Client Support Ends
NodeReal, a key infrastructure contributor to BNB Chain, will discontinue support for the Erigon client, with the complete sunset scheduled for December 31, 2025. This decision encourages all Erigon operators to plan their migration to alternative clients well before the deadline. NodeReal's strategy aligns with the community's focus on fostering a robust and future-ready client ecosystem.
Introduction of Reth
In a move to bolster network performance, BNB Chain is introducing support for Reth-BSC, a high-performance client based on Rust. Reth promises improved speed, reduced resource usage, and a modular design, positioning it as a next-generation client capable of meeting the evolving demands of blockchain applications.
Commitment to Client Diversity
To maintain a resilient and secure network, BNB Chain is committed to supporting a multi-client ecosystem. Officially recommended execution clients now include Reth and Geth, the latter being a Go-based client. This transition reflects a community-driven decision to strategically evolve the client ecosystem, focusing resources on high-performance clients like Reth.
The decision to phase out Erigon and embrace Reth and Geth ensures strong client diversity, crucial for the network's security and stability. Node operators currently using Erigon are advised to initiate their migration to Reth or Geth before the year-end deadline.
Migration Recommendations
BNB Chain strongly recommends starting the testing and migration process early to ensure a seamless transition. Resources to facilitate this migration are available, including repositories on GitHub for Reth, BSC, and Reth-BSC.
