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. Depth comes from required reading, interactive labs, reflection, and a hands-on check with evidence — the BOSS study pattern.

Research on Bitcoin Search

Required reading

  • bookMastering Bitcoin

    Ch. 3: Bitcoin Core

Reflection prompts

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

Lab // Project milestone evidence

For Node Dashboard, complete the linked project spec happy path on regtest/Polar and capture demo evidence before marking the lesson complete.

evidence required

  • ·Link to public repo or branch
  • ·Commands or screenshots proving the happy path
  • ·Short note of one failure case you tested

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

Build challenge

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.

Proxy RPC

Browser clients must hit your backend, not bitcoind directly.

Next steps

Build a Payment Processor API that creates invoices and tracks confirmations.
