BNB Chain has announced a significant technical advancement with the successful integration of Erigon 3, the latest Ethereum client, into its native Parlia consensus protocol. This upgrade is set to launch on the mainnet around September 30, 2024, marking a pivotal step in enhancing network performance, scalability, and efficiency for BNB Smart Chain (BSC) users.
The integration combines the speed and security of Parlia—a hybrid consensus mechanism blending Delegated Proof-of-Stake (DPoS) and Proof-of-Authority (PoA)—with the advanced architecture of Erigon 3, known for its optimized data storage and fast synchronization capabilities. This synergy is expected to deliver substantial improvements, particularly for developers and node operators running archive nodes, which store the complete history of blockchain transactions.
What Is Parlia and Why It Matters
Parlia is the core consensus engine powering BNB Chain. It enables high-speed transaction processing and low fees by allowing BNB token holders to elect trusted validators who secure the network. Unlike traditional PoW systems, Parlia ensures rapid finality and energy efficiency, making it ideal for decentralized applications (dApps) requiring real-time interactions.
With millions of active dApps and users relying on BSC’s infrastructure, maintaining optimal node performance is critical. However, as the blockchain grows, so does the burden on full and archive nodes—especially in terms of disk usage and sync time. This is where Erigon 3 steps in.

Erigon 3: A Leap Forward in Node Optimization
Originally developed as an alternative Ethereum implementation written in Go, Erigon has evolved into one of the most efficient blockchain clients available. The newly adapted Erigon 3 introduces major enhancements tailored specifically for BNB Chain's architecture.
During testing on the BSC Chapel testnet, Erigon 3 demonstrated impressive results:
- 50% reduction in disk space usage compared to previous versions
- Synchronization time dropped from one week to just 10 hours
These improvements mean that running a full or archive node becomes significantly more accessible, reducing hardware requirements and lowering entry barriers for independent validators and developers. Faster sync times also enable quicker deployment of services such as block explorers, analytics platforms, and decentralized exchanges that rely on historical data.
Additionally, reduced storage demands lower operational costs for node providers, contributing to a more decentralized and resilient network over time.
Smooth Transition: Supporting Both Erigon 2 and 3
To ensure a seamless migration path, BNB Chain will continue supporting Erigon 2 for a transitional period after the mainnet launch of Erigon 3. This dual-support strategy allows node operators, exchanges, and infrastructure providers to upgrade at their own pace without risking service disruptions.
The current Erigon 3 Alpha 2 version is already live on the testnet, inviting community participation in testing and feedback collection. Developers are encouraged to deploy nodes, monitor performance, and report issues to help refine the final release.
This open collaboration reflects BNB Chain’s commitment to community-driven development and long-term ecosystem sustainability.

Q: How does Erigon 3 benefit regular BSC users?
A: While end users may not notice immediate changes, the upgrade enhances backend infrastructure. Faster nodes lead to improved reliability of wallets, exchanges, and dApps—all of which depend on accurate, timely blockchain data.
Q: When will Erigon 3 go live on the mainnet?
A: The mainnet release is scheduled for approximately September 30, 2024. The exact date may vary slightly based on final testnet results and community feedback.
Q: Do I need to upgrade my node now?
A: If you operate a node on BSC, it’s recommended to begin testing with Erigon 3 Alpha 2 on the Chapel testnet. However, there’s no urgent requirement—Erigon 2 will remain supported during the transition phase.
Q: Is this upgrade related to a token swap or network fork?
A: No. This is a backend client upgrade focused on performance optimization. There is no change to the BNB token, smart contract compatibility, or user wallets.
Q: Where can I find documentation or technical guides?
A: Official resources and integration guides will be published on BNB Chain’s developer portal ahead of the mainnet launch. Community forums and GitHub repositories are also valuable sources for technical details.
Strengthening BNB Chain’s Infrastructure Roadmap
This integration is more than just a performance patch—it represents a strategic investment in BNB Chain’s long-term viability.
