# Consensus Clients

Consensus client database size varies widely with amount of blobs kept. The below is a baseline with the minimal amount of blobs. A "supernode" can easily
add 500 GiB to that number in blob space alone. An archive blob node would take over 4 TiB of blob data.

| Client | Version | Date | DB Size | RAM | Notes |
|--------|---------|---- |----------|------|-------|
| Teku | 24.8.0 | Sep 2024 | ~84 GiB | ~10 GiB |
| Lighthouse | 4.5.0 | Jan 2024 | ~130 GiB | ~5 GiB |
| Nimbus | 24.1.1 | Jan 2024 | ~170 GiB | ~2 to 3 GiB |
| Prysm | 4.1.1 | Jan 2024 | ~130 GiB | ~5 GiB |
| Lodestar | 1.13.0 | Jan 2024 | ~130 GiB | ~8 GiB |

Notes on disk usage
- Teku, Nimbus, Lodestar, Prysm and Grandine continuously prune
- Lighthouse can be resynced in minutes to bring space usage back down, with `./ethd resync-consensus`
- Lighthouse is working on tree states to continuously prune
