# Sentinel SCA Adds Read-Only ROKO Network Monitoring

Sentinel SCA has added its first read-only ROKO network monitoring capability.

This is an early but important milestone: Sentinel can now observe live ROKO network state, read recent blocks from the ROKO explorer, compute health signals, and record local tamper-evident monitoring evidence.

The first phase is deliberately read-only. Sentinel is not yet writing decision hashes on-chain, and it does not require a wallet or private key for this stage.

What Sentinel Now Monitors

Sentinel’s ROKO monitor connects to the live ROKO explorer and tracks:

  • Latest block height
  • Latest block hash
  • Validator address
  • Block timestamp
  • Block interval
  • API latency
  • Transaction count
  • Gas used
  • Health alerts
  • Local evidence digest

In our live validation, Sentinel successfully observed ROKO blocks with a consistent block interval of about 3 seconds and detected the active validator:

Sentinel also generated local block and sample digests, allowing the monitor result itself to become evidence.

Why This Matters

Sentinel is built as a runtime governance layer for autonomous systems.

Most governance tools only inspect internal application events. Sentinel’s direction is broader: it should be able to observe external infrastructure that an autonomous agent, enterprise workflow, or blockchain-connected system depends on.

ROKO monitoring is a first example of that model.

Sentinel can now answer questions such as:

Is the ROKO explorer reachable?
Is the chain producing blocks?
Is block production delayed?
Has the validator changed?
Is the latest observed network state recorded?
Can we prove what Sentinel observed at a specific time?
Enter fullscreen mode Exit fullscreen mode

That turns blockchain infrastructure health into part of Sentinel’s evidence layer.

What Was Validated

The live monitor successfully returned:

Status: healthy
Latest block: observed
Block time: 3.0 seconds
Validator: detected
API latency: ~330ms
Alerts: none
Audit record: written locally
Enter fullscreen mode Exit fullscreen mode

A recorded health snapshot was stored in Sentinel’s audit trail:

/app/audit/roko_monitor.jsonl
Enter fullscreen mode Exit fullscreen mode

A later sample showed a new block height and a different digest, proving Sentinel was not just reading a static response. It was observing live network movement and producing fresh evidence.

What This Is Not Yet

This is not yet on-chain anchoring.

Sentinel is not currently sending transactions to ROKO or writing Sentinel decision hashes on-chain. That is a future phase and will require a stricter security design:

  • Dedicated testnet wallet
  • RPC endpoint
  • Signing policy
  • Key custody rules
  • Transaction failure handling
  • No raw customer data on-chain
  • Hash-only evidence anchoring

The current phase is intentionally safer: observe first, record locally, validate the signal, then decide how to write.

Roadmap

Phase 1: ROKO Monitor v0.1

Completed.

Sentinel can read live ROKO block data, compute health metrics, and record local tamper-evident evidence.

Phase 2: Continuous ROKO Audit Loop

Next.

Sentinel should run the monitor automatically, record snapshots over time, and expose recent ROKO health history through Ops or an API endpoint.

Phase 3: ROKO Evidence Anchoring

Future.

Sentinel decision hashes can be anchored to ROKO once wallet, RPC, custody, and transaction policies are safely designed.

Why The Order Matters

The goal is not to rush blockchain writing.

The goal is to build credible evidence.

A governance system should first prove it can observe external infrastructure correctly. Then it should prove it can record that observation. Only after that should it write evidence on-chain.

That is the path Sentinel is following:

Observe
↓
Hash
↓
Record
↓
Audit
↓
Anchor
Enter fullscreen mode Exit fullscreen mode

Conclusion

Sentinel SCA’s ROKO monitor is now live in read-only mode.

It proves that Sentinel can observe live blockchain infrastructure, detect health conditions, and record local evidence without exposing secrets or requiring wallet custody.

This is a practical first step toward blockchain-backed governance evidence: not a claim, not a concept, but a working monitor reading live ROKO network state today.
