The BSC Testnet Chapel archive node has a size of 463GB on March 17th, 2025

Setup of BSC Erigon

This guide covers the installation of BSC Erigon V3, which is Erigon V3's fork managed by Node-Real. It has built-in snapshot download function and allows to sync BSC Testnet Chapel archive Node in effecteively 48 hours. It is important to keep in mind that the client is still under development and you need to be prepared to face difficulties during synchronization or other techincal issues

Pre-Requisites

sudo apt update -y && sudo apt upgrade -y && sudo apt autoremove -y

sudo apt install -y libgtest-dev libomp-dev libgmp-dev git make wget aria2 gcc pkg-config libusb-1.0-0-dev libudev-dev jq g++ curl libssl-dev screen apache2-utils build-essential

Setting up Firewall

Set explicit default UFW rules

sudo ufw default deny incoming
sudo ufw default allow outgoing

Allow SSH and peers

sudo ufw allow 22/tcp
sudo ufw allow 30303 #p2p port
sudo ufw allow 42069 #torrent port

Allow remote RPC connections with the Node

sudo ufw allow from ${REMOTE.HOST.IP} to any port 8545 #http api port
sudo ufw allow from ${REMOTE.HOST.IP} to any port 8546 #ws port

Not advised to allow all or unknown IP address to RPC port

Enable Firewall

sudo ufw enable

To check the status of UFW and see the current rules

sudo ufw status verbose

Install GO

Go version 1.22+ is required

sudo wget https://go.dev/dl/go1.22.4.linux-amd64.tar.gz && sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.22.4.linux-amd64.tar.gz && rm go1.22.4.linux-amd64.tar.gz

echo 'export PATH=$PATH:/usr/local/go/bin:/root/.local/bin' >> /root/.bashrc

source /root/.bashrc

#verify Go installation
go version

Build Erigon RPC Node

git clone --recurse-submodules https://github.com/node-real/bsc-erigon.git

cd bsc-erigon

Check for the latest actual release at https://github.com/node-real/bsc-erigon/releases

This guide has been tested and successfully synced the node with v1.3.2-beta2:

git checkout v1.3.2-beta2

make erigon

Create Data directory and jwt secret file

cd ..

mkdir -p /root/data/bsc-erigon/

openssl rand -hex 32 | tr -d "\n" > /root/data/bsc-erigon/jwt.hex

Create Systemd service for BSC Erigon

sudo nano /etc/systemd/system/bsc-erigon.service

Paste the configs and save by entering ctrl+X and Y+ENTER:

Replace {IP} with the actual address of the server in order to to explicitly set the external IP address that the node should advertise to peers in a P2P network

Launch BSC Erigon

sudo systemctl daemon-reload #refresh systemd configuration when changes made

sudo systemctl enable bsc-erigon.service #enable bsc-erigon.service at system startup

sudo systemctl start bsc-erigon.service #start bsc-erigon.service

sudo nano /etc/systemd/system/bsc-erigon.service #make changes in bsc-erigon.service file

Monitor the logs for errors

journalctl -u bsc-erigon.service -f -n 100 #follow logs of bsc-erigon.service

During the inizializtion, first you are expected to see logs of a snapshot download process :

If the download progress shows 0% for too long, try restarting the client. Once the snapshot has been fully downloaded and applied by the client, the node will start syncing process and will reach a chainhead in under 48 hrs

Run curl command in the terminal to check the status of your node

curl -H "Content-type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}' http://localhost:8545

When it returns false then your node is fully synchronized with the network
