Total Supply
-
This dashboard estimates how much Bitcoin supply is exposed to quantum-risk spending paths at a selected block-height snapshot.
It combines chain-derived aggregates with attribution metadata to show exposed supply, exposed pubkeys/UTXOs, estimated migration pressure, and the largest exposed entities or addresses.
Discontinued research dashboard. The last published legacy snapshot is block 961,000; no new Quantum snapshots are scheduled. An audit found accounting and methodology limitations, so these figures are historical output, not corrected results. The replacement was not validated or published. Read the findings.
