Bounty #2311: The Fossil Record — Attestation Archaeology Visualizer (75 RTC)

Claimed by: kuanglaodi2-sudo
Wallet: C4c7r9WPsnEe6CUfegMU9M7ReHD1pWg8qeSfTBoRcLbg

What Was Implemented

Interactive D3.js visualization of RustChain attestation history, rendered as geological strata by architecture family.

Files: tools/fossil_record.py, tools/static/fossil_timeline.html, tools/fossil_record_README.md

Flask API Server (fossil_record.py):

• GET /api/timeline — Stratigraphy data from RustChain node API
• GET /api/archs — Architecture summary stats
• GET /api/epochs/<id> — Epoch detail
• Falls back to realistic demo data when node unreachable

D3.js Visualization (fossil_timeline.html):

• X-axis: epoch (time progression)
• Y-axis: architecture family (oldest at bottom, newest at top)
• Block opacity: attestation density
• Hover tooltip: miner ID, attestation count, RTC earned, miner count
• Architecture color scheme:
  • 68K: deep brown/obsidian
  • PowerPC G4: amber/gold
  • PowerPC G5: copper
  • SPARC: deep ocean blue
  • POWER8: slate/navy
  • RISC-V: teal
  • x86: pale gray
• Filter controls: epoch range, bucket size
• Summary stats: total epochs, attestations, RTC distributed, arch families

Usage

pip install flask requests
python tools/fossil_record.py --port 5002
# Open http://localhost:5002

Thanks for your interest! These PRs have issues: PR #1748 destructively overwrites the project README, multiple PRs contain placeholder data, and 7 high-value bounty claims in one day from a 22-day account suggests bulk generation. Please review our contribution guidelines — start with one small, complete PR and build from there. Quality over quantity.
