On-chain crypto evidence

Crypto charts you can actually check.

On-chain evidence with visible source, freshness, and what the data cannot prove, starting with stablecoin supply.

The Hard Data publishes reusable crypto chart pages, each with its source, last-updated date, and a plain note on what it can and cannot prove. The first shelf covers stablecoin supply: concentration, by chain, and total tracked balances.

Evidence method

A market question needs a source trail, not a take.

The trail starts with one evidence question, then links the data to a safe chart view, table, and clear claim limit. The view follows the data shape, not a house format.

Question

Evidence question

Start with one concrete market question before selecting a source, metric, or chart type.

Fit

Evidence fit

Classify the claim as composition, trend, ranking, snapshot, or another reviewed shape before rendering.

View

Safe chart view

Use line, bar, area, or table only when both the data shape and claim limit make that view safe.

Table

Audit table

Keep rows, units, denominator, source coverage, and freshness inspectable beside the visual.

Boundary

Cannot support

Name what the evidence cannot prove before turning a useful chart into a broader market claim.

Evidence method

The question comes first. The chart order follows the evidence.

We define the question, write a citable quick answer, bind it to chart evidence and a baseline, and keep what the data cannot prove close to the conclusion.

Read the method →

Frame the question

A research note states one market question and the condition that would weaken the answer.

Write the quick answer

The lead answer must carry a number, denominator, freshness, and baseline before it can carry confidence.

Publish evidence and boundary

Source, freshness, chart evidence, and what the evidence cannot prove stay with the conclusion.

Research questions

The site is built around crypto charts, not noise.

These short answers clarify what the public site is for, how chart evidence is sourced, and when a market question needs more than one visual proof.

What kind of crypto charts does The Hard Data publish?

The Hard Data publishes reusable crypto charts that answer specific market questions with visible sources, freshness, and caveats. The site focuses on chart evidence rather than generic dashboard screens.

Where does the on-chain data come from?

Each public chart keeps its source, metric definition, and freshness close to the claim. Source coverage can expand over time, but a dataset has to be reviewed before it becomes public evidence.

How are chart pages different from research notes?

A chart page is a standalone evidence object. A research note explains metric boundaries, caveats, and the evidence trail when a market question needs more context.

What stablecoin supply evidence is live now?

The current stablecoin supply pages cover issuer concentration, supply by chain, and total tracked balances. Other crypto metrics can be added after their source coverage and claim limits are reviewed.

Why do some answers include caveats?

Crypto market claims are easy to overstate. The Hard Data keeps caveats visible when a metric has coverage limits, provider differences, delayed freshness, or a question that needs more than one chart to answer responsibly.
