Proof · Receipts and Verify
Don't trust the number. Check it.
Every figure in Voltfin carries a receipt: the dataset, its version, the row, the block and the providers that agreed. Verify re-runs those reads in your browser, so no server has to be trusted for the result.
Proof
What you do with it.
Verify in the browser
Re-run the reads yourself; the result does not depend on our servers.
Honest proof levels
Each number states how far it has been verified, and a derived value takes its weakest input's level.
