Learning objectives

Poll or stream Bitcoin Core status metrics
Visualize sync progress, peer counts, and mempool size
Alert on stalled IBD or RPC failures

study // plan

Lessons are primers. Start with Step 1 (required reading) when present, then follow the numbered steps in the article. Depth comes from primary sources, labs, reflection, and evidence.

Reflection prompts

Explain Node Dashboard to a teammate without jargon - what problem does it solve?
What would break in production if you misunderstood Node Dashboard?
Which BIP, book chapter, or Core doc is authoritative here, and what did you verify?

Lab // Project milestone evidence

Complete Steps 2–4. Ship a dashboard that polls Core via a backend proxy and capture demo evidence before marking complete.

evidence required

Link to public repo or branch
Screenshot showing height/peers/mempool (or equivalent panels)
Short note of one failure case (RPC down, stalled sync)

Operators need situational awareness. A node dashboard turns RPC into signals: are we synced, connected, and estimating fees sanely?

Complete Step 1 // Required reading in the study plan above, then continue here.

Step 2 — Goal

Dashboard panels:

Chain height / headers / verification progress
Peer count
Mempool size + feerate estimates
Optional wallet balances for a monitoring wallet

Loading diagram…

Poll Core safely and render snapshots; never expose RPC to browsers.

Done when: You can list the RPC calls behind each panel.

Step 3 — Milestones

Phase	Ship
Milestone A	Backend proxy + `getblockchaininfo` / peer snapshot
Milestone B	Mempool + fee estimate panels with refresh
Milestone C	Alert or banner for RPC failure / stalled IBD

Done when: Milestone A never exposes RPC credentials to the browser.

Step 4 — Build & evidence (lab)

Implement against /projects/node-dashboard. Capture repo link, panel screenshot, and one failure case.

Common mistakes

Polling too aggressively and starving the node
Exposing cookie/RPC auth to the frontend
Treating regtest peer count (often 0) as a production outage without context

Done when: Lab evidence is filed.

Apply what you learned in a focused build session. Ship something small, test it on regtest, and document your approach before moving on.
