Blockchain address-attribution data

Blockchain address-attribution data: labels linking on-chain addresses to real-world entities, in particular the distinction between an exchange or custodial service provider's deposit address and an ordinary individual's wallet. The published methodology describes a four-signal evidence model that the underlying dataset must implement: behavioural clustering over time (high inbound volume from unrelated senders, automated sweeping of deposits into consolidation wallets, and related deposit-address patterns), an explicit evidence hierarchy ranking corroborating sources, and legal verification to a standard defensible in an affidavit or court filing. The asset is therefore a curated, evidence-graded ground-truth table of address-to-entity assignments with confidence tiers, oriented to law-enforcement and compliance consumers (state and local investigators, fraud examiners, compliance reviewers) who need to know whether a subpoena and preservation notice against an exchange is the correct next step. Public fraud-report context is referenced via the FBI Internet Crime Complaint Center.
