# Tempo

> Run an Ethereum-compatible Tempo node (reth-based) — Agent-only

Tempo is an Ethereum-compatible chain. A Tempo node runs a single reth-based `tempo` process in **follow mode** (no local consensus engine) and serves the standard Ethereum JSON-RPC. On first deploy it bootstraps from a snapshot; if the snapshot isn't available it syncs from peers instead.

Tempo runs **only on a bare-metal executor (Agent)** — it isn't offered on the Kubernetes (Operator) backend. To provision a host, see [Provision on bare-metal](/recipes/provision-on-bare-metal).

To deploy, open **Deploy Node**, pick **Tempo**, then choose a network.

## Networks and resources

| Network    | CPU      | RAM    | Disk     |
| ---------- | -------- | ------ | -------- |
| `mainnet`  | 16 cores | 32 GiB | 1000 GiB |
| `moderato` | 16 cores | 32 GiB | 1000 GiB |

`moderato` is Tempo's test network. Defaults are pre-filled in the deploy wizard.

## Node type

**Full** only — a reth `--full` node that keeps full history and follows the chain; it takes no part in consensus.

## Ports

| Name                 | Port    | Notes                   |
| -------------------- | ------- | ----------------------- |
| JSON-RPC (HTTP)      | `8545`  | Ethereum-compatible RPC |
| Metrics (Prometheus) | `9000`  |                         |
| P2P                  | `30303` | Peer discovery and sync |

Ports are managed for you and aren't user-overridable.

## Configuration

Tempo runs with a managed configuration — the chain, data paths, and RPC/P2P wiring are set for you; there are no client config overrides at deploy time.

## Metrics

Block height, peers, and sync progress are surfaced in the node view — see [Node monitoring](/docs/nodes/monitoring).

## What you can build

* **Public RPC node** — accept the defaults and expose `:8545` (HTTP) behind your own proxy.
