This guide covers day-to-day operations for running a Tempo validator in production.

Validator management differs depending on which ValidatorConfig version is active:

- **[ValidatorConfig V2](/guide/node/validator-config-v2)** (post-T2) — self-service key rotation, IP updates, and ownership transfers
- **[ValidatorConfig V1](/guide/node/validator-config-v1)** (pre-T2, legacy) — all management operations require coordinating with the Tempo team

For validator states and lifecycle transitions, see the respective V1 and V2 pages.

# ValidatorConfig V2

ValidatorConfig V2 ([TIP-1017](/protocol/tips/tip-1017)) is a new precompile for managing consensus participants. It replaces the original ValidatorConfig with stronger safety guarantees: ed25519 signature verification at registration, append-only history, and self-service operations for validators.

V2 was [activated on mainnet](https://explore.mainnet.tempo.xyz/receipt/0x4716147e3c2bf5c8d014b8c27d6e2af0042d5a5f29bdead256d6f33038702d64) after the T2 hardfork.

## Validator states

With V2, the syncer warmup phase from V1 is removed. Once added, a validator immediately becomes a player in the next epoch.

Compare this to the [V1 validator states](/guide/node/validator-config-v1#validator-states), which required an additional syncer epoch before becoming a player.

## What changes for operators

With V2, validators can perform several operations themselves without coordinating with the Tempo team:

If your node's network endpoints change, update them on-chain. The change takes effect at the next finalized block.

Unlike V1, V2 supports asymmetric ingress and egress IPs — they no longer need to share the same address. Both can be updated together or individually by supplying only `--ingress` or `--egress`. The values not supplied will pulled from the chain and left unchanged in the submitted transaction.

### Rotate validator identity

V2 lets you rotate to a new ed25519 key while keeping your validator index stable. This is useful for key rotation or recovery without leaving and re-joining the committee. [Generate a new signing key](#generating-a-signing-key) first.
The ed25519 key can be changed while keeping your validator index stable. This is useful for key rotation or recovery without leaving and re-joining the committee. [Generate a new signing key](#generating-a-signing-key) first.

The simplest way to rotate is using the `tempo` CLI, which handles signature creation and the on-chain transaction in one step:

## Differences from V1

| | V1 | V2 |
|---|---|---|
| **Key ownership** | No verification | Ed25519 signature required |
| **History** | Mutable, toggle active/inactive | Append-only, deactivate-once |
| **Validator index** | Could change | Stable for lifetime |
| **Self-service ops** | None (owner only) | IP updates, rotation, transfer |
| **Historical queries** | Required warmup state, bloated snapshots | `addedAtHeight` / `deactivatedAtHeight` fields |

If you do not see logs like these:
- please check that your validator is part of the active set, and is both a player and a dealer (see validator states under [V2](/guide/node/validator-config-v2#validator-states) or [V1](/guide/node/validator-config-v1#validator-states))
- please check that your validator is part of the active set, and is both a player and a dealer. See [validator states](/guide/node/validator-config-v2#validator-states)
- please check that your node is synced up to the [latest block height](https://explorer.tempo.xyz/).
- please check that your outgoing IP address matches the one whitelisted on the validator smart contract:
