Proof Infrastructure for Finance

Make approvals, transactions, and controls in financial services independently verifiable — proving what happened to regulators and counterparties without exposing sensitive data.

The problem

Financial institutions run on high-stakes events: payment approvals, transaction settlement, sanctions screening, and controls that must satisfy regulators. Each of these events is recorded in internal systems, but the record is only as trustworthy as the institution that maintains it.

When a regulator, counterparty, or court needs to confirm that a control ran or an approval occurred, they must either trust the institution’s logs or be granted privileged access to internal systems — both of which are slow, costly, and imperfect.

The trust gap

Logs and reports can be edited, back-dated, or selectively presented, and confirming them requires trusting the party that produced them. Redacting sensitive data to protect privacy weakens the evidence, while exposing it creates risk. There is no way to prove an event happened without either trusting a system or revealing private information.

The Proof Infrastructure approach

A proof artifact in this context

Proof artifact sealed
type:proof_of_approval
event:Wire transfer > $250,000 approved
issuer:org:northbank / role:treasury-controller
data_commitment:sha256:4f1b…d09a
signature:ed25519:8a3c…f52e

Sensitive details are committed to via a hash — the proof carries no private data.

Example verification flow

  1. 1A regulator receives the proof of approval for a flagged transaction.
  2. 2They recompute the commitment to confirm the transaction details are unaltered.
  3. 3They validate the signature and confirm the controller was authorized.
  4. 4They confirm the timestamp — establishing the approval happened before funds moved.
  5. 5Compliance is confirmed independently, with no access to customer accounts.
