What are the minimum hardware requirements to run a Kaspa node?

To run a Kaspa node, you need at least 8 GB of free RAM and a 64-bit CPU — with a couple of free CPU cores strongly recommended. Under normal operation a node uses only about 3 GB of RAM and almost no CPU (less than 1%), so modest hardware is fine for day-to-day use. However, when the node is syncing from scratch, or when the DAG structure becomes more complex, RAM usage can climb to 8 GB or more, and a faster CPU will meaningfully shorten the time it takes to finish that initial sync. For a beginner, the practical takeaway is: 8 GB of free RAM is the safe baseline — running with less may cause the node to fail during sync.
