Overview

NeuroCrypt is the public identifier for a privately financed proof-of-presence program. Continuous operation is dated conservatively at 41 years. Earlier construction records are held and not fully reconciled.

Presence attestations bind three values only: an identity commitment, a timestamp, and a witnessed state hash. Geometry, headcount, and related figures used in other extracts are controlled only at NC-REG-0002. Construction continuity is discussed under NC-INC-0001.

Enrollment has been closed since inception. The synchronization instrument expects a previously provisioned identity commitment. A rejected synchronization creates no program record.

Three programs share Ring time. Method is published in the released note series. Operational history appears in the incident register. The document register is the inventory of what exists as a controlled holding at this extract.

The extract serves a subset of the controlled document set at Tier 0. The documents served are the internal documents, released or redacted under NC-GOV-0001; they are not summaries prepared for release. Where a document is served in part, the omission is marked in the document rather than repaired.

Every identifier names the office that originated the holding. An office that has been dissolved does not have its holdings reattributed. The classification scheme itself is described at NC-GOV-0001.

An attestation does not establish what a subject did, intended, or understood. It establishes that the subject was present. The substrate has no field in which anything further could be recorded; nothing was omitted by decision.

NeuroCrypt does not claim that its own account of its operation is complete. Fourteen incidents are registered and eleven are sealed. The oldest open item has been open for the whole of the program's continuous operation and has no finding.

This extract is not maintained in real time and carries no live figure. Quantities are those in force at the effective date shown on each document.
