Risk label provenance

A risky address is not one blacklist.

The same address can appear in official sanctions, explorer tags, commercial intelligence, and community reports. FlowTrace preserves source, version, verification time, and evidence count before deciding whether to warn, review, or block.

Collection policy

Method version 2026-08. Prefer official downloads, APIs, and on-chain events over scraped search-result HTML. Full snapshots retain a version and SHA-256 and deactivate labels removed by the source; community reports always require review.
