Erigon 3 – New Erigon Client for BSC: Synchronization Time Reduced from Weeks to 10 Hours

##Introduction

Erigon 3 is a cutting-edge Ethereum client, now tailored for the BNB Chain with full Parlia consensus protocol integration. This upgrade is crucial for BSC, where speed and cost efficiency are essential to supporting its expansive decentralized application ecosystem. With these enhancements, Erigon 3 meets BNB Chain’s unique operational needs and delivers significantly improved performance for users.

Parlia Consensus Mechanism

Parlia is the consensus mechanism powering the BNB Chain. It merges features from Delegated Proof of Stake (DPoS) and Proof of Authority (PoA), allowing for faster block production and lower transaction costs. In Parlia, BNB holders elect validators, blending DPoS’s decentralization with PoA’s efficiency. This hybrid design is vital for BSC’s high throughput and scalability, making it a top choice for developers.

Integrating Parlia into Erigon 3 marks a major milestone. This enables the client to fully support BSC’s operational requirements. By combining Parlia’s hybrid consensus with Erigon’s optimized architecture, users—especially those running Archive nodes—benefit from notable performance gains.

BSC Testnet – Synchronization Time Significantly Improved

On the BSC testnet, Erigon 3 achieves a substantial reduction in disk usage. Test results show that overall disk consumption decreases by 50%, cutting hardware costs for node operators. Synchronization speed sees even greater gains: On the Chapel testnet, Erigon 3 syncs in about 10 hours, compared to roughly a week with earlier versions. These advances allow users to deploy and maintain blockchain nodes far more efficiently.

Current Status

The Erigon team has successfully ported the Parlia consensus protocol used by BSC into Erigon 3’s latest Alpha 2 release. This ensures complete compatibility with the BNB Chain and lets users take advantage of Erigon’s performance optimizations and reduced resource needs. Testnet snapshots are available, and users can try Erigon Alpha 2 on the testnet. Since the software remains in alpha, user testing and feedback are encouraged to help identify any remaining issues. With Erigon 3, there’s no need to manually download snapshots—just run the client, and the latest snapshot downloads automatically.

Mainnet Roadmap

Mainnet synchronization is underway. Since the new snapshot isn’t compatible with Erigon 2, the team targets a mainnet release in Q4 2025. To ensure a smooth transition, support for Erigon 2 will continue for a period to give users time to migrate.

Getting Started

Building with Git and Compilation

To build Erigon from source: Clone the repository from GitHub (git clone --recurse-submodules), enter the directory (cd bsc-erigon), check out Alpha 2 (git checkout v1.3.0-alpha2), and compile the binary with make erigon. The compiled binary will be in ./build/bin/erigon.

Downloading Precompiled Binaries

You can also download precompiled binaries to save time. After downloading the tar.gz file, extract it with tar -xvzf bsc-erigon_1.3.0-alpha2_linux_amd64.tar.gz.

Using Docker Images

For containerized deployment, pull the Docker image with docker pull ghcr.io/node-real/bsc-erigon:1.3.0-alpha2.

Startup Command

Start the Erigon client with: ./erigon --datadir="<your_data_path>" --chain=chapel --txpool.disable --diagnostics.disabled --batchSize=2g --http.port=8545 --private.api.addr=127.0.0.1:9090 --http --ws --http.api=eth,debug,net,trace,web3,erigon. Replace "<your_data_path>" with your actual data directory, and be sure to use the right binary for your operating system.

Conclusion

Erigon 3’s launch is a major leap for blockchain client development. With full Parlia consensus integration, Erigon 3 is now fully compatible with the BNB Chain and delivers substantial improvements in both sync time and disk usage—reducing synchronization from weeks to just 10 hours and halving disk requirements. These enhancements let users deploy blockchain nodes with greater efficiency and lower costs. While Erigon 3 is still in alpha, its potential is already clear. As the mainnet version rolls out and user feedback drives further refinements, Erigon 3 is set to become a core infrastructure component for the BSC ecosystem.

FAQ

What is Erigon?

Erigon is an Ethereum client written in Go, known for its disk efficiency and high performance. It supports archive nodes and alternative blockchains like Polygon and BNB Chain, and is one of Ethereum’s two most popular clients.

How is Erigon different from other Ethereum clients, such as Geth and Nethermind?

Erigon prioritizes efficiency and easy interaction. By default, it operates as a full archive node, unlike Geth. Erigon is more accessible and resource-efficient, while Geth focuses on security and full blockchain verification.

What are the main features and advantages of using Erigon?

Erigon’s modular architecture enables parallel development, and it reduces database read/write operations to boost performance and efficiency.

How do you launch and configure an Erigon node?

Install Git, Go, and Docker. Clone the Erigon repo from GitHub, build it with make, and run it via Docker for a full Ethereum node.

Is Erigon suitable for staking and running validators on Ethereum?

Yes. Erigon is well-suited for staking and running validators. It fully supports Ethereum staking through the built-in Caplin consensus client, allowing validators to participate efficiently in the network.
