A-08 tool · multi-hop graph · Bitcoin

Follow a flow across 1 to 3 hops,
without hiding the scoring rule.

The graph queries the public Blockstream API when you ask it to. No key, no account, no address stored server-side. Every score point shows its measure; the summary is deterministic by default, and an LLM can only be connected if you configure it yourself.

network: Bitcoin source: Blockstream API hops: 1–3 nodes: max 30 transactions: max 25 / address score: additive

Build the graph

Public Bitcoin address only. Your browser calls Blockstream; this site neither receives nor stores the request.

Examples:
Ready. Enter an address or choose an example.
Deliberate caps: 25 transactions per address, 12 new addresses per hop, 30 nodes. A truncated graph is flagged; it does not claim completeness. Edge values are output amounts, not an exact accounting attribution.

Risk score — detail

Sum capped at 100. Each row shows the rule, the measure and the proof.

A high score is an investigation priority, not proof. A low score does not clear anyone.

Graph edges

Observed output amounts, aggregated by pair and transaction.

A-08 Convergence — patterns, proofs, confidence

The engine does not look for an identity: it detects flow shapes (fan-in, fan-out, transit, splitting, burst, exposure) and returns an additive score. Every point carries a measure and a proof. The score measures intensity; confidence measures data quality.

Limits and guards

    The SYNTHETIC badge marks a local fixture with no real address. The LIVE badge marks a Blockstream graph built on demand. No automatic conclusion: a convergence opens a human review.

    Summary — deterministic by default, LLM only if configured

    The local summary is reproducible. The LLM connector is optional, stored in your browser, and sends only the public graph data.

    No summary yet.
    Configure an LLM (optional)
    No key is sent to the site; it stays in this browser.
    Guardrail: an LLM never replaces the score. If the call fails or no key is configured, the deterministic summary is displayed and the reason is stated.

    Limits of this graph

    Bitcoin only. Ethereum, BNB Chain and TRON are not queried here: they need an Etherscan V2 key or an indexer. A-01 remains a scenario for those networks.
    No identity. An address is not a person, and an exchange is not a taxpayer. The graph shows public movements, never an ownership link.

    Source: blockstream.info/api, public API without a key. Data may be incomplete or unavailable; the build date is shown in the summary. French and English pages share the same engine; this page is the English restitution.
