Hardware requirements

The hardware requirements for running an ETN-SC node depend upon the node configuration and can change over time as upgrades to the network are implemented. Electroneum nodes can be run on low power, resource-constrained devices such as Raspberry Pi's. However, many users will choose to run nodes on laptop or desktop computers.

Processor

It is preferable to use a quad-core (or dual-core hyperthreaded) CPU. Etn-sc supports a wide range of architectures.

Memory

It is recommended to use at least 16GB RAM.

Disk space

Disk space is usually the primary bottleneck for node operators. At the time of writing (March 2024), Electroneum Smartchain is in its infancy, a 200GB SSD is recommended for a full node running ETN-SC. Archive nodes require additional space. We recommend at least 500GB SSD for a "full" archive node that keeps all state back to genesis. Partial archive nodes can also be created by turning off the garbage collector after some initial sync - the storage requirement depends how much state is saved.

As well as storage capacity, ETN-SC nodes rely on fast read and write operations. This means HDDs and cheaper SSDs can sometimes struggle to sync the blockchain. A list of SSD models that users report being able and unable to sync ETN-SC is available in this GitHub Gist. Please note that the list has not been verified by the Electroneum team.

Bandwidth

It is important to have a stable and reliable internet connection, especially for running a validator, because downtime can result in missed rewards or penalties. It is recommended to have at least 25Mbps download speed to run a node. Running a node also requires a lot of data to be uploaded and downloaded so it is better to use an ISP that does not have a capped data allowance.
