Disk and RAM sizing

The testnet chain is small. It started on Sep 24 2026 and at 75 seconds per block grows by about 1,150 blocks a day.

zecnerod follows Zebra and keeps the full chain. There is no pruning mode. Plan disk space for the whole chain plus growth.

Rough guidance for testnet​

MinimumComfortable
CPU2 cores4 cores
RAM4 GB8 GB
Disk20 GB SSD50 GB SSD

These numbers leave room to spare. Use an SSD; spinning disks make sync and state updates slow.

TODO

Measure current testnet chain size and node memory use and replace the table with measured figures. Add a Mainnet estimate before launch.

Mining on the same machine​

If you also run the miner on the node host, add about 2.5 GB of RAM for the RandomX dataset and expect slower sync while mining.
