How to Run a Validator on BNB Smart Chain

Welcome to the tutorial on “How to Run a Validator on Binance Smart Chain”. In this guide, we will walk you through the process of setting up a validator node on the Binance Smart Chain (BSC) and running it effectively.

Validators play a crucial role in maintaining the security and stability of a blockchain network by validating transactions and producing new blocks. Running a validator on the BSC can be a profitable venture, as it rewards participating nodes with Binance Coin (BNB) tokens.

Whether you are a seasoned blockchain professional or a beginner looking to learn more about the technology, this tutorial will provide you with a step-by-step guide on how to get started with running a validator on the Binance Smart Chain. So let’s get started!

Validator Hardware Requirements​

  • VPS running recent versions of Mac OS X or Linux.

  • IMPORTANT 2T GB of free disk space, solid-state drive(SSD), gp3, 8k IOPS, 250MB/S throughput, read latency <1ms (if start with snap/fast sync, it will need NVMe SSD)

  • 16 cores of CPU and 64 gigabytes of memory (RAM)

  • Suggest m5zn.3xlarge instance type on AWS, or c2-standard-16 on Google cloud.

  • A broadband Internet connection with upload/download speeds of 10 megabytes per second

Setting up Validator Node​

Install BSC Fullnode​

Follow the instructions on how to run a full node

Start Validator Node​

 

Warning

Please do not expose your RPC endpoints to the public network.

## generate the consensus key and input the password
echo {your-password to the mining account} > password.txt
geth --config ./config.toml --datadir ./node --syncmode snap -unlock {the address of your mining account} --password password.txt  --mine  --allow-insecure-unlock --cache 18000

 

Post Running​

Monitor node status​

To get started quickly, run GethExporter in a Docker container.

docker run -it -d -p 9090:9090 \
  -e "GETH=http://mygethserverhere.com:8545" \
  hunterlong/gethexporter

 

 

Update the validator profile​

You can submit a PullRequest to this repository to update your information: Reference:

Publish Validator Information​

Please submit a Pull Request to this repo

This repository is a place for validator candidates to give potential delegators a brief introduction about your team and infrastructure, and present your ecosystem contributions.

Stop Validating​

You can stop mining new blocks by sending commands in geth console

Connect to your validator node with geth attach ipc:path/to/geth.ipc

miner.stop()

 

To resume validating,

miner.start()
