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.

Fullnode Installation
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

echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
Optimization
sudo sysctl vm.swappiness=10
sudo nano /etc/sysctl.conf
