You should select an all-purpose server with

• at least 4 GB of RAM,
• good connectivity (esp. port 26656), and
• a solid-state drive with at sufficient disk space.

As the usage of the blockchain grows, the server requirements may increase as well, so you should have a plan for updating your server as well.

Storage

The monthly storage requirements for a node are as follows. These are estimated values based on experience but should serve as a good guide:

• With the current block cadence of 5 seconds/block:
  • a full Devnet node (with the default pruning=syncable) grows at the rate of ~6GB/month (approximately 200MB/day)
  • an archiving Devnet node (with pruning=nothing) grows at the rate of ~12GB/month (approximately 400MB/day),
