CSI proof block.

CSI proof block, 2019.

One published proof: the CSI value and data-state, the methodology version and confidence, the content-addressed hashes, the off-chain evidence pointers and the previous-proof chain link.

Back to the proof ledger.View the CSI dashboard.

This proof block anchors one published CSI snapshot. Every value is derived from declared candidate inputs, carries an explicit data-state label and stays provisional until authenticated production lineage and the benchmark trusted gate pass. A missing or fail-closed proof renders as an explicit unavailable state, never a fabricated value.

Position in the append-only chain

This page shows the latest entry for 2019. Entries are append-only: a re-certification appends a new entry for a period rather than editing the earlier one, and the earlier entry stays in the chain labelled revised.

In plain English

CSI 2019 snapshot (provisional).

Free-public composite CSI for WORLD 2019: the weighted composition of the eight first-class sub-indexes. Illustrative and provisional until a reproducible production pipeline certifies a release.

The summary above is the block's own hashed text, written when the block was certified and preserved verbatim; the current publication state is the data-state label at the top of this record (derived from declared candidate inputs and provisional: certified on the candidate track, not yet benchmark-trusted).
