Bitcoin live, explained without hype
Network stress, large transfers, transaction briefs, and practical tools—built from public APIs with clear limits. No price calls. No identity claims.

Rough fee estimate in sats and header fiat from recommended rates—actual vsize and confirmation time vary.
Mempool size, suggested fees, difficulty adjustment estimate, and chain tip—refreshed on the same cadence as the large-transfer feed (sourced from mempool.space over the public API).

Flow-of-funds and entity tagging usually need paid products or server-side jobs. This site stays a static client; follow these services if you need dashboards beyond what public APIs expose.
Methodology and data sources
- Transaction brief: explains transaction structure using local heuristics only. It can point to patterns such as consolidation, split outputs, possible self-transfer, known address hints, and fee priority. It cannot determine intent.
- Large-transfer context: scans recent blocks from the chain tip via mempool.space. A row appears when the sum of outputs meets your threshold (default 100 BTC). That is not the same as a single UTXO, net flow, or “coins leaving an entity.”
- Exchange address hints: a small static label list may flag inputs or outputs touching known deposit addresses. That is not proof of buying, selling, or entity identity—many rows stay “no label match.”
- Sample addresses: labels are for illustration; always verify any address on a block explorer before relying on it.
- Fear & Greed: daily series from alternative.me; treat it as a sentiment indicator, not a decision rule.
- Network snapshot: mempool, fee estimates, and difficulty timing come from mempool.space; halving ETA assumes about ten minutes per block.
- Session digest: counts transaction IDs this browser has seen (stored in localStorage). It does not sync between devices.

Hub tabs: Brief, Blocks, Mining & LN, DCA & Time, Convert &
sats, and Alerts fetch when opened (Overview loads with the page). URLs use hashes such as
#lookup. Satoshi calculators sit under Convert & sats. - Fiat spot prices: CoinGecko’s free tier (rate-limited) with blockchain.info USD as a fallback if the request fails.
- DCA & historical spot: CoinGecko daily USD closes; cached in localStorage for roughly twelve hours per date range.
- Alerts & PWA: notifications only run while the site is open in a tab; install uses the manifest and service worker (offline shell—live figures still need the network).
