Configuring Soft Node

Soft nodes are a type of node in a blockchain network that maintains only a partial copy of the blockchain instead of a full copy. These nodes rely on other nodes, typically full nodes, to provide them with necessary information such as block headers or transaction data. Light nodes consume fewer resources compared to full nodes, making them suitable for devices with limited computational power or storage capacity. While light nodes sacrifice some level of security and independence compared to full nodes, they still contribute to the decentralization of the network by verifying transactions and participating in the consensus process.

System Requirements​

System prerequisites to become a soft node:

  • CPU: 8 Core

  • RAM: 16 GB

  • Storage: Solid State Drive (SSD) with a minimum capacity of 50GB

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: (Optional)​

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

Remember to 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 Soft Node​

Run the below command to start node syncing​

nohup ./jumbo --config ./config.toml --datadir "directory" --syncmode full --cache 2048 --rpc.allow-unprotected-txs --txlookuplimit 0 &

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
