About these numbers
Incident selection
This dashboard covers reported incidents, not every attack or the relative safety of a chain. Each verified canonical incident is counted once. Unverified, rejected, merged duplicate, pending-review, and future-dated records are excluded. Late reports and corrections can change recent periods.
Loss and outliers
Reported loss sums known positive USD amounts. Missing amounts stay unknown, not zero. Median incident loss uses only incidents with a known amount. “Exclude the largest incident” removes the largest known-loss event from both the selected and comparison periods.
Missing classifications
Sector and chain labels come from the incident record. Uncategorized incidents are excluded from sector charts; incidents without a named chain are excluded from chain charts. A multi-chain incident appears under each named chain, so those counts overlap.
Limitations
Reliable malicious-actor attribution is not consistently available, so this page does not rank actor groups. Timing alone cannot show that AI caused an attack, so there is no AI-involvement metric. Confirmed returned funds are too sparsely documented for a recovery trend: 2 of 356 incidents in this view have comparable reviewed accounting, totaling $1.9M.
