Privacy-preserving Trust Infrastructure
Trust Infrastructure for institutions that need to verify without over-collecting.
ZeroAttest helps institutions build Trust Infrastructure: design privacy-preserving verification workflows, connect to the right sources of truth, and run them through a production verification desk.
End the need to retain customer-supplied PII documents.
Trust Infrastructure examples
These examples show the kinds of Trust Infrastructure ZeroAttest can design and deploy for institutions. Each engagement starts with workflow and policy design, then moves into source-of-truth integration, platform configuration, and production rollout. The examples below illustrate reusable patterns, not one-size-fits-all templates.
A compliance-style demo: show you are not on the OFAC Specially Designated Nationals (SDN) list by proving your document identifier is absent from the published list, without disclosing the identifier to the verifier. Use it to see how sanctions-style screening can be framed as a zero-knowledge predicate.
Prove a Bitcoin custody or wallet balance clears a minimum threshold, without disclosing the full balance, UTXO structure, or other holdings. The verifier sees only that the policy line is satisfied, the same pattern as other threshold proofs adapted to on-chain balances.
A capital-markets pattern: attest that portfolio or account value clears a regulatory threshold (here, the accredited-investor bar) without exposing the balance, custodian, or account identifiers. Only the “meets threshold” conclusion is argued in the proof.
Combine several predicates in one session: attributes you choose to assert, backed by private inputs you hold locally. The demo illustrates flexible identity-style proofs where the verifier learns only the claims you enable, not the full underlying profile.
User & verifier
The person being verified opens a secure link from the institution. Institutions use the verification desk to issue requests, monitor case status, and act on outcomes without ingesting raw customer documents. ZeroAttest configures this Trust Infrastructure around the institution’s policies, acceptable sources of truth, and operational review process.

“Everything I say in zero knowledge is guaranteed to be true; I can choose to say nothing at all; and everything I do not say is perfectly hidden.”Mary Maller (2023)
How it works
Age gates, KYC, sanctions, and capital-markets rules often force full-document exposure. Zero-knowledge proofs let institutions verify precise predicates instead. Trust Infrastructure means defining the policy logic, acceptable sources of truth, and review workflow first, then operationalizing that design through the ZeroAttest platform. The proof builder at demo.zeroattest.com shows how teams compose custom policies, and the verification desk shows the full institution-and-applicant lifecycle once those templates are operational.
Claims anchored to source data or witness material. Design institution-specific attestations once, then run them repeatedly as part of your Trust Infrastructure.
Counterparties see the conclusion the policy allows, not the whole file. Trust Infrastructure reduces unnecessary document handling, attack surface, and aggregate liability.
Connect Trust Infrastructure to the registries, custodians, counterparties, or internal systems each institution already relies on.
Trust Infrastructure in practice
ZeroAttest is not just a point solution. We help institutions build Trust Infrastructure by defining the claims they need, identifying acceptable sources of truth, configuring verification policies, and running those workflows through the ZeroAttest platform.
Map the workflow, define the claims to be proved, and identify the policies and sources of truth that fit the institution’s requirements.
Configure verification logic, integrate with the right registries, custodians, or internal systems, and launch pilot or production flows.
Use the verification desk to issue requests, monitor case status, review outcomes, and operate recurring verification programs.
Use Cases
The pattern is the same wherever a regulator or counterparty needs confidence without a data warehouse of secrets. Trust Infrastructure means combining workflow design, source-of-truth integration, and reusable verification software so institutions can deploy privacy-preserving verification across multiple use cases.
KYC/AML, sanctions screening, credit signals, and accredited status, with institution-specific Trust Infrastructure and less exposure to full statements or identity packets. See the live demos for sanctions and accredited-investor examples.
Trial eligibility, coverage checks, device compliance, without broadcasting PHI beyond what the policy requires.
Credentials, supplier attestation, access decisions, with less replication of sensitive attributes across systems.
Age, status, and reporting predicates where civil-liberty and data-minimization goals align with the math.
Selective disclosure, anonymous membership proofs, and SSO-adjacent flows that stop at the attribute, not the whole account.
