Hardware Requirements
The hardware requirements listed on this page are the suggested minimum requirements. It might be possible to configure a system with less resources, but you run the risk of being underprovisioned and thereby prone to loss of stake.
The Oasis Network is composed of multiple classes of nodes that participate in different committees. The majority of committees have common system configurations for the participant nodes.

Consensus Nodes

To run a non-validator or a validator consensus node, your system should meet the following minimum system requirements:
    2.0 GHz x86-64 CPU
The CPU must have AES-NI support.
    4 GB ECC RAM
Ordinary node operation can work with 2 GB of RAM.
However, at certain time points, it absolutely requires at least 4 GB of RAM. Examples of such more resource intensive time points are the initial state sync, BadgerDB migration when upgrading a node to Oasis Core 21.2.x, ...
If you can dynamically change the amount of RAM a node is provisioned, then feel free to downscale/upscale it as you see fit.
    100+ GB High Speed Storage
The network accumulates state over time. The speed at which the state grows depends on the network's usage.
For example, the Mainnet accumulated over 80 GB of state in 5+ months between Mainnet launch (Nov 18, 2020) and Cobalt upgrade (Apr 28, 2021).
Node doesn't need to keep the state from before the latest dump & restore upgrade (e.g. before the Cobalt upgrade). Historical state can be archived separately.
It is also possible to configure the Node to not keep all the state from the genesis onward, reducing the amount of storage needed to keep the network's state.
To do that, set the consensus.tendermint.abci.prune.strategy and consensus.tendermint.abci.prune.num_kept parameters appropriately in your Node's configuration.

ParaTime Nodes

To run a ParaTime node, your system should meet the following minimum system requirements:
    2.0 GHz x86-64 CPU
The CPU must have AES-NI support.
If you want to be able to run ParaTimes which require the use of a Trusted Execution Environment (TEE), the CPU needs to support Intel SGX.
    8 GB ECC RAM
    100+ GB High Speed Storage
