Reth Node for BSC¶

BSC Reth is a cutting-edge Rust client developed in collaboration with Paradigm, designed to provide seamless support for BNB Smart Chain (BSC). It aims to enhance client diversity on the BNB Chain by offering a secure and efficient execution client.

Hardware Specifications¶

To run BSC Reth effectively, ensure your system meets the following hardware requirements:

CPU with 16+ cores
128GB RAM
High-performance NVMe SSD with at least 4TB of free space for a full node and 8TB for an archive node
Broadband internet connection with upload/download speeds of 25 MB/s

Running BSC Reth¶

Download source code and build binary.

git clone https://github.com/bnb-chain/reth.git
cd reth
make build-bsc

Start the reth node, it will run in archive mode by default. You can add the --full flag to start a full node.

# for mainnet
export network=bsc

# for testnet
# export network=bsc-testnet

./target/release/bsc-reth node \
    --datadir=./datadir \
    --chain=${network} \
    --http \
    --http.api="eth, net, txpool, web3, rpc" \
    --log.file.directory ./datadir/logs

Optionally, you can run the reth node with docker.

# for mainnet
export network=bsc

# for testnet
# export network=bsc-testnet

# check this for version of the docker image, https://github.com/bnb-chain/reth/pkgs/container/bsc-reth
export version=latest

# the directory where reth data will be stored
export data_dir=/xxx/xxx

docker run -d -p 8545:8545 -p 30303:30303 -p 30303:30303/udp -v ${data_dir}:/data \
    --name bsc-reth ghcr.io/bnb-chain/bsc-reth:${version} node \
    --datadir=/data \
    --chain=${network} \
    --http \
    --http.api="eth, net, txpool, web3, rpc" \
    --log.file.directory /data/logs

Snapshot¶

To synchronize a BSC reth node from scratch to the current block height can be a time-consuming process. As We benchmark Reth(v1.0.0) on AWS lm4gn.8xlarge(32 core 128G) with 2 x 7500 NVMe SSD for BSC mainnet. It may take approximately 30 days to sync the latest block on BSC mainnet for an archive node and 24 days for a full node.

Given the extended duration required for stage synchronization of the BSC network, the BNB Chain team is developing a segmented snapshot download solution, scheduled for release in the near future. Currently, developers seeking to expedite the process can obtain archive node snapshots from community-maintained repositories. These snapshots offer a faster alternative to syncing from genesis, allowing for quicker node setup and network participation.
