Low-Cost Infrastructure
Located in Hamburg and operating locally on a low-cost / low-maintenance infrastructure at home
Currently operating two Relays and one Block-Producer nodes distributed in three Raspberry-Pis model 4 of 8 GB
Each Relay is connected to different Relays to maximise connectivity making use of the community tool Topology Updater. In order to prevent down-time with any of the blocks, a systemctl “daemon” takes control of the running script and automatically restarts them in case of unexpected failure
Nodes operate 24/7 without the need of cloud storage which increases the reliability and security of the process, given that no external source is introduced
The two Relay / one Block-Producer setting, with the current versions of the cardano-node, is very stable and solid fail-safe which guarantees that the Block-Producing node is always fed with the blockchain
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 and cardano-node main operations are r/w ones)
Internet Connection
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. Moreover Chrony is enable to ensure proper time synchronisation at all time
The Raspberry Pi's
Aarch64 architectures provide a really low power consumption (10W, combining for a total of 30W). This is a very cheap & eco-friendly solution to contribute to the network. The local set-up adds an extra layer of security when it comes to preventing undesired accesses
