Hardware requirements
Data availability nodes
Non-archival data availability nodes
| Node type | Memory | CPU | Disk | Bandwidth |
|---|---|---|---|---|
| Light node | 500 MB RAM | Single core | 20 GB SSD | 56 Kbps |
| Bridge node | 64 GB RAM | 32 cores | 25 TiB NVME | 1 Gbps |
Non-archival disk recommendations use a 7-day planning window sized for the 128MB/6s maximum-throughput envelope, which provides headroom above the current maximum block capacity of 32 MiB at approximately 3-second blocks. These are conservative recommendations; operators may provision less by pruning more aggressively at their own risk.
Bridge nodes run in pruned mode by default.
Archival data availability nodes
| Node type | Memory | CPU | Disk | Bandwidth |
|---|---|---|---|---|
| Light node (unpruned headers) | 500 MB RAM | Single core | 7 TiB NVME* | 56 Kbps |
Bridge node (--archival) | 64 GB RAM | 32 cores | 637 TiB NVME* | 1 Gbps |
*Archival disk recommendations use a 1-year planning window sized for the 128MB/6s maximum-throughput envelope, which provides headroom above the current maximum block capacity of 32 MiB at approximately 3-second blocks. Actual usage can be much lower. Regularly check disk usage and maintain at least 1 month of maximum-throughput capacity as additional free space.
To run an archival bridge node, start with a fresh store and pass --archival
every time you run celestia bridge start. A store previously started in pruned
mode cannot switch to archival mode.
Consensus nodes
Non-archival consensus nodes
| Node type | Memory | CPU | Disk | Bandwidth |
|---|---|---|---|---|
| Validator | 32 GB RAM | 32 cores | 12 TiB NVME | 1 Gbps |
| Consensus node | 32 GB RAM | 32 cores | 12 TiB NVME | 1 Gbps |

Archival consensus nodes
| Node type | Memory | CPU | Disk | Bandwidth |
|---|---|---|---|---|
| Consensus node | 64 GB RAM | 32 cores | 624 TiB NVME* | 1 Gbps |
*Archival disk recommendations use a 1-year planning window sized for the 128MB/6s maximum-throughput envelope, which provides headroom above the current maximum block capacity of 32 MiB at approximately 3-second blocks.

Validators must use hardware that passes the CPU benchmark . If your server does not pass, upgrade to a more powerful machine.
For a list of CPUs tested against the v6 128MB/6s workload, see the release notes . Other CPUs are acceptable if they pass the benchmark. Recommended CPU specs:
- 32 or more cores
- GFNI (Galois Field New Instructions) support
- SHA-NI (SHA New Instructions) support
