feat: HacScan — Hacash On-Chain Analytics & Whale Tracker

[enioxt]

Problem

The Hacash community has been asking for on-chain analytics for months. Key pain points from Telegram:

• Xeggex rug pull wallets need tracking (20+ mentions)
• No labeled address database exists anywhere
• No HACD ownership distribution or top holder rankings
• No historical supply/hashrate/difficulty charts

Proposal

Build HacScan — an on-chain analytics dashboard at egos.ia.br/tools/hacscan

Features (MVP)

• Labeled address database (Xeggex wallets, exchange hot wallets, mining pools, dev fund)
• Top HAC holders ranked
• HACD ownership distribution (concentration %)
• Supply metrics over time (minted, burned, channel deposits)
• Large transfer alerts from labeled wallets

Features (Phase 2)

• Mining hashrate + difficulty trend charts
• Block production rate analysis
• Historical profitability data
• Community-submitted labels (verified)

Tech

• React page on egos-web
• Vercel serverless for data aggregation + caching
• Supabase for label storage
• Hacash RPC (nodeapi.hacash.org) for live data

Data Sources

• Hacash fullnode RPC
• Manual label DB from community intelligence (Xeggex addresses already shared in Telegram)
• Derived metrics from block scanning

No Duplication

• explorer.hacash.org covers block/tx/address lookup — we do NOT replicate that
• We focus on analytics, labels, and trends that nobody else provides
