Total Supply
-
This dashboard estimates how much Bitcoin supply is exposed to quantum-risk pathways, and who controls that exposure, at a selected block-height snapshot. It combines chain-derived aggregates with attribution metadata to show both macro risk (total exposed supply, exposed pubkeys/UTXOs, migration pressure) and micro concentration (largest exposed entities/addresses).
What "quantum exposure" means here
Supply is treated as exposed when spending conditions reveal public key material or otherwise create script paths considered vulnerable under a future cryptographically relevant quantum threat model. The dashboard does not predict when such a threat arrives; it quantifies current and historical exposure surfaces under consistent rules.
