Fullnode

Defichain Fullnode

To stabilize the network, it is possible to setup a Defichain Fullnode on a virtual or physical server with a fixed IP address. A Fullnode hold the whole blockchain without acting as a masternode (no Collateral required) and other Nodes and Wallets in the network can use it to synchronize. Everyone in the community can help make the network more stable with a public Fullnode.

Ubuntu 16.04/18.04/20.04

Create Swapfile

recommended for Systems less then 4 GB sudo fallocate -l 4G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile

Check the swapfile sudo swapon --show

make the Swapfile permanent sudo cp /etc/fstab /etc/fstab.bak echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab

Optimization sudo sysctl vm.swappiness=10 sudo nano /etc/sysctl.conf vm.swappiness=10
