Low-Cost Infrastructure
Located in Hamburg and operating on a low-cost / low-maintenance infrastructure
Currently operating two Relay nodes and one Block-Producing node distributed in three Raspberry-Pis model 4 of 8 GB
Each Relay is connected to different Relays to maximise connectivity, using the topology updater tool. In order to prevent down-time with the nodes, a systemctl “daemon” process ensures its correct functioning
Nodes operate 24/7 without the need of service providers which increases the reliability and security of the process, given that no external source is introduced
The 2 Relay set-up with the current node versions and “daemons” is very solid fail-safe process which guarantees that the Block-Producing node is always safely connected
Ubuntu booted from USB3
The Operating System is Ubuntu 20.04 and, in order to prevent Hardware failure, is booted from a USB3 stick. (SD cards that constantly read and write fail after a short while)
Internet Connection
High-speed internet connection provides readings of 60 Mbps and 12 Mbps of download/upload which leads to a 3ms ping. More than enough to be synchronised at all times. Chrony is also enabled to ensure proper time synchronisation
The raspberry Pi
The Hardware architecture of the Raspberry Pi is Aarch64. Common HW makes use of X86 instead which is more power consuming. Each one of the Raspis consumes 10W (nothing compared to others). It is a cheap and eco-friendly way of contributing to this amazing project
