Arkham Tracks 78% of Strategy’s 847,700 BTC Holdings

Arkham's labeling turns a deliberately opaque corporate treasury into a partially auditable on-chain position, which matters for anyone assessing counterparty or custody risk around the largest corporate bitcoin holder. The unresolved slice, plus Saylor's stated refusal to disclose addresses, keeps full verification out of reach — a reminder that on-chain attribution is a disclosure choice as much as a technical feat. Whether the remaining holdings get tagged, and whether custody labels like Fidelity's become a de facto standard, is the open question.
