BTC CAMPFIRE / OBSERVATORY

A living network.
A clearer perspective.

Let the fire slow you down. Let the data show you what actually changed.

Latest saved observation: 2026-10-02T05:31:29.112Z. BTC/USD: 86334.3 (fresh, source time 2026-10-02T05:31:28.000Z). One-hour fee estimate: 1 sat/vB. Block: 969538. Source: mempool.space.

Formula, coverage and source

BTC dominance = 100 × BTC capitalization / eligible capitalization. Both views exclude wrapped representations. The second excludes the union of wrapped assets and stablecoins. Every asset slug is counted once; multi-chain totals are not added. An asset can appear in more than one category. Duplicate slugs with identical capitalization are merged and all category memberships retained; conflicting capitalization rejects the snapshot. Missing capitalization values are excluded and counted.

A change in market capitalization is not a measured inflow of money. This definition differs from providers with other coverage. History is not combined across methodology changes. Data by CoinSpectrum, CC BY 4.0; asset-union methodology v2.

BITCOIN FUEL MIX

What paid the miners?

Waiting for the canonical block sample.

How we calculate this

Fee share = sum(transaction fees) / sum(coinbase rewards), with claimed subsidy = coinbase reward − fees. We report the sample and block range. The target window is the latest 144 canonical blocks, which is not exactly 24 hours. A smaller complete sample is explicitly labelled. Invalid rewards or a gap prevent a result.

Allowed subsidy is determined separately at each block height. The coinbase can claim less. Reward structure alone does not quantify Bitcoin’s security. Source: mempool block API; see also Bitcoin Core block statistics.

THE CAMPFIRE FIELD GUIDE

How to read Bitcoin data without confusing activity with price

A Bitcoin dashboard is useful only if you know what each number measures. A quoted price, a block timestamp, a fee estimate and a visitor poll can all look current while describing different things. Start with three questions: what is the unit, what is the observation time, and what was counted? This dashboard puts those questions beside the visuals rather than leaving them in a disclaimer.

Read three clocks, not one

The market clock observes a quote from a particular venue. The chain clock records a block header supplied by a network observer. The collector clock says when our server obtained that information. None is interchangeable with the others. If the quote changes while the latest block remains the same, the site is not necessarily stuck: exchange activity and block discovery are different processes. Conversely, a successful page refresh does not make an old observation new.

Use the block ribbon to ask a better question

The ribbon encodes block weight, not transaction value. Two equally tall bars can contain different transaction counts because transactions have different structures. Selecting a bar reveals the actual count and fees. Compare that with the separate rhythm chart: a short time interval can accompany a full block, and a long interval can accompany a lightly used one. One chart describes occupied capacity; the other describes header-time gaps. Neither is a price signal.

For example, imagine block A contains 2,000 transactions and block B contains 3,000. That observation alone cannot establish that 50% more people paid, that 50% more value moved, or that demand for bitcoin rose by 50%. A transaction can have several recipients, and the same participant can create multiple transactions. A useful dashboard lets you explore the observation without silently adding those conclusions.

Separate a ratio from the thing being divided

Dominance changes when the numerator, denominator or both change. In a simple hypothetical market with $1.5 trillion of Bitcoin, $1 trillion of other eligible assets and $0.5 trillion of stablecoins, Bitcoin represents 50% with stablecoins and 60% without them. The ten-percentage-point difference requires no Bitcoin price change at all. Our two views use one asset snapshot and one documented exclusion rule so that this denominator effect is visible. They do not make either definition the only correct definition.

Look at weighted rewards, not the brightest square

The revenue atlas makes unusual blocks easy to spot. Its brightest cell is not the average. To obtain the sample’s fee share, we divide the sum of fees by the sum of claimed rewards. Averaging the percentages would give every block the same influence, even when their rewards differ. The distinction matters when one unusually fee-heavy block appears among many quieter blocks. Select that cell, then compare it with the aggregate ring rather than treating it as a new normal.

A practical one-minute reading routine

These tools are designed to support curiosity and repeatable comparisons. They do not combine the inputs into a buy/sell score. For source field definitions, see Bitcoin Core block statistics; for the dominance universe and attribution, see CoinSpectrum’s API.

A window, not a prediction

Quotes, estimates, header times and visitor votes answer different questions. Every view names its source and observation period. Analytical snapshots use a shared one-minute schedule and HTTP observation times. The main campfire and price-fire lab separately use Kraken’s public trade stream with exchange timestamps; these views can show different moments. A mempool.space fallback is explicitly labelled and may differ. Stale observations are labelled. An unavailable source is not a zero. Our briefing is composed directly from validated values; it makes no unsupported explanation for market moves.
