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.
Requirements
General
- Fixed IP-Address
- Port Forwarding enabled on Router (Port 8555)
- 24/7 online
- Stable Internetconnection (Upload)
Hardware
- 100 GB free disk space (SSD recommended)
- 2-4 vCPU
- 4 GB Memory
Software
- Debian 19, 64 Bit
- Ubuntu 16.04 LTS
- Ubuntu 18.04

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
