# Node > **Status:** Current (generated) A validator's own port, not exposed by the gateway: raw submission, Prometheus metrics, safety checks, fault injection. | Function | Kind | Description | |---|---|---| | [`chain.evidence`](#chainevidence) | read | Slashing: proofs of equivocation this validator holds (for relaying to where the key is bonded), offences recorded here, jailed nodes, the key registry | | [`chain.commit_hashes`](#chaincommit_hashes) | read | Fingerprints of consecutive commits from `from`, for checking that validators agree (`mox check`) | | [`node.set_fault`](#nodeset_fault) | write | Switch this validator's injected fault at runtime (builds with the `testnet-faults` feature only), for fault campaigns | | [`tx.submit_raw`](#txsubmit_raw) | write | Submit signed transactions without JSON or hex, for high-rate clients: the body is each transaction as a 4-byte little-endian length and its bytes; the reply has, per transaction, 0 and the 32-byte hash, or 1, a 2-byte length and the error | | [`node.status`](#nodestatus) | read | A validator's status over plain HTTP (the same as chain.status), for health checks | | [`node.metrics`](#nodemetrics) | read | A validator's metrics in the Prometheus text format | | [`node.events_stream`](#nodeevents_stream) | stream | Contract events from one validator as Server-Sent Events (the gateway relays this as events.stream) | | [`node.dag_stream`](#nodedag_stream) | stream | One validator's live DAG as Server-Sent Events (the gateway relays this as events.dag_stream) | ## chain.evidence Slashing: proofs of equivocation this validator holds (for relaying to where the key is bonded), offences recorded here, jailed nodes, the key registry. - **Kind:** read - **Runs:** JSON-RPC `mox_evidence` (`POST /`) on the a validator's own RPC port only (not through the gateway) **Input** None. **Output** An object. | Field | Type | Required | Description | |---|---|---|---| | `proofs` | array of object | | | | `offences` | array of object | | | | `jailed` | array of integer | | | | `validators` | array of object | | | ## chain.commit_hashes Fingerprints of consecutive commits from `from`, for checking that validators agree (`mox check`). - **Kind:** read - **Runs:** JSON-RPC `mox_commitHashes` (`POST /`) on the a validator's own RPC port only (not through the gateway) **Input** | Field | Type | Required | Description | |---|---|---|---| | `from` | integer | | First commit | | `limit` | integer | | Most to return | **Output** An object. | Field | Type | Required | Description | |---|---|---|---| | `from` | integer | | First commit returned | | `hashes` | array of string | | | | `oldest` | integer or null | | | | `newest` | integer or null | | | ## node.set_fault Switch this validator's injected fault at runtime (builds with the `testnet-faults` feature only), for fault campaigns.
