## Requirements

| Resource | BlockPro planning baseline                   |
| -------- | -------------------------------------------- |
| CPU      | 4+ cores                                     |
| RAM      | 16 GB+                                       |
| Storage  | 500 GB+ fast SSD; expand for archive history |
| OS       | Ubuntu 24.04 LTS, x86-64                     |

These are operational planning values, not an upstream guarantee. Measure snapshot size, free space and workload before provisioning. The source repository is the authority for build dependencies.

Allow inbound P2P on TCP `26656`. Keep RPC `26657`, REST `1317` and gRPC `9090` private unless you are deliberately operating a protected public service. Use a separate server for each network.

## Versions

Reference release: [`v0.8.4`](https://github.com/nolus-protocol/nolus-core/tree/v0.8.4). The tag includes the leading `v`. Build from the release tag, not the development branch.

Read the version reported by the network before installation or upgrade; this response is live and is not cached in this guide.

```bash
curl -fsS https://nolus-api.block-pro.net/cosmos/base/tendermint/v1beta1/node_info | jq '{chain: .default_node_info.network, version: .application_version.version}'
```

If the endpoint is unavailable, confirm the active release with the project’s official validator announcements. Do not guess from the highest GitHub tag.
