60+ sources.
Real-time sentiment.
A terminal ahead of its time.

BlockBeat aggregated crypto news across 60+ sources with market sentiment scoring. Shut down in 2024.

BlockBeat ran for 18 months as a real-time crypto intelligence terminal — a cyberpunk-aesthetic newsroom where every article arrived with a sentiment score, every coin had a rolling sentiment curve, and an AI newsletter hit inboxes every morning summarizing the previous 24 hours. Sunset in 2024.

[ WHAT WE BUILT ]

A full crypto intelligence stack.

News Aggregation
60+ Sources via NewsAPI.ai

Real-time feed with sub-minute latency from publication. Every major crypto media outlet, financial wire, and influential blog — centralized in one terminal.

Sentiment Engine
Per-article NLP Scoring

Each article scored bullish / bearish / neutral using NLP. Scores aggregated per coin (BTC, ETH, SOL, and more) and displayed as rolling sentiment curves updated in real time.

Price Overlay
TradingView + Supabase Cache

Live coin prices surfaced alongside relevant news — TradingView widgets embedded inline, Supabase-cached price data updated on a tight polling interval.

AI Newsletter
Daily digest. Auto-generated.

Every morning an AI-written newsletter hit subscribers' inboxes — a concise summary of the previous 24 hours in crypto, automatically generated from the aggregated feed.

[ DESIGN ]

A terminal, not a blog.

AESTHETIC
CYBERPUNK TERMINAL

Full-bleed dark UI. Monospace type throughout. Green-on-black data displays. Dense information layout designed for power users.

HISTORY
18 MONTHS · SUNSET 2024

BlockBeat ran for a year and a half before being shut down in 2024. The architecture lives on — the real-time aggregation and NLP pipeline have been adapted for other projects.
