Configuring Validator Node

Validator nodes are pivotal elements within Jumbo Blockchain’s Proof of Nexus (PoN) consensus mechanism, instrumental in the validation of transactions and the proposal of new blocks for incorporation into the blockchain. These nodes undertake the critical responsibility of ensuring transaction adherence to network regulations, actively participating in the consensus mechanism, and upholding network integrity. Validator nodes are rewarded for their contributions with transaction fees or block rewards, bolstering network security and decentralization. PoN blockchain network employs a system of periodic selection and rotation of validator nodes to prevent centralization and foster inclusivity and diversity.

System Requirements​

System prerequisites to become a validator node:

  • CPU: 12 Core (16 core recommended for high performance)

  • RAM: 32 GB

  • Storage: Solid State Drive (SSD) with a minimum capacity of 100GB

Configuring​

Download the following files from github https://github.com/jumbochain/go-jumbo-setup

  • jumbo
  • config.toml
  • genesis.json

Initialize genesis to “directory”​

./jumbo --datadir "directory" init genesis.json

For creating a new account​

./jumbo --datadir "directory" account new
warning

Remember or save your password as you won't be able to retrieve it later is lost. We recommend writing it on a paper.

warning

Remember to backup your keystore, to prevent losing keystore on data loss. We recommend storing it separately.

Start Validator Node

Run the below command to start node syncing​

nohup ./jumbo --config ./config.toml --datadir "directory" --syncmode "full" --unlock "address" --password password.txt --allow-insecure-unlock --mine --miner.jumbobase="address" &

To check logs​

tail -f "directory"/jumbo.log

Check Status

After chain is successfully initiated.

./jumbo attach "directory"/jumbo.ipc

In the terminal enter the following command​

Jumbo.syncing

if false then chain is synced successfully
