A mapping from EthSystems' Institutional Privacy Map to the proof-of-concepts this program builds. Each row names the map artifacts we answer, what we built, the current status, and where to read the detail. Status as of 2026-07-30.
What these are. Demo-grade evidence on fictional data, not product: no SLA, no certification, nothing here is a production service. The Graph indexes public chain state and adds no confidentiality of its own; read privacy does not exist on any of these paths. Every claim on every linked page is backed by an artifact someone re-ran, or is labelled as not yet run.
▶ Check any of this yourself, live
Open the verification page — it reads the bond's anchored commitments and roots straight off Ethereum Sepolia in your browser, and rebuilds the encrypted anchor stream from raw transaction calldata. No API key, no install, and nothing from The Graph in the trust path. Everything below is meant to be re-derivable without us; that page is where you re-derive it.

Nothing here states what we have not run ourselves. The honesty rules that bind every row — The Graph is a read and audit path, not a privacy technology; attestations are signatures, not validity proofs; completeness is bounded by what the chain records; read privacy does not exist today — are set out in full on each page's Honest limits section.
