pqcintent.com & .eth | PQC Intent Identity

BIS Papers No. 158 makes a precise and consequential point: the quantum-safe transition must not be treated as simple algorithm replacement. Ensuring continued security and resilience of the global financial system requires cryptographic agility, defense in depth, hybrid models, and phased migration — a coordinated institutional decision, not an isolated technical patch applied by an IT department.

This creates a documentation gap that did not previously exist. Before any institution swaps a cryptographic algorithm securing settlement, custody, or counterparty authentication, there must be a recorded intent: which systems were inventoried, which algorithm generation was selected, what hybrid period was authorized, and how this timing was coordinated with the broader financial ecosystem the institution operates within. Without this documented intent, BIS’s cryptographic agility principle cannot be demonstrated to examiners — only claimed.

pqcintent.com & .eth is the Convergence Identity for this pre-migration authorization standard — the institutional namespace connecting the coordinated, documented intent that BIS, the G7 Cyber Expert Group, and the Basel Committee all require before any cryptographic algorithm transition begins.

Why BIS’s Cryptographic Agility Principle Requires Documented Migration Intent

The “Harvest Now, Decrypt Later” threat creates a precise authorization timing problem: adversaries are already collecting encrypted data today with the intent to decrypt it once quantum capabilities mature, meaning the decision to migrate — and exactly when — carries consequences for data that has already been transmitted and is sitting in adversary archives. An institution that documents its migration intent today, even before completing the technical transition, creates a defensible record that it identified and acted on this risk in a timely manner.

NIST recommends hybrid deployments combining traditional and post-quantum algorithms during the transition, so that security holds even if one approach is later compromised — but a hybrid deployment is itself a documented choice requiring intent: which traditional algorithm remains, which post-quantum algorithm is added, and for how long the hybrid period is authorized to run. The MCI intent identity for the broader authorization framework within which cryptographic migration intent operates is documented at mciintent.com & .eth.

The G7 Cyber Expert Group’s coordinated roadmap explicitly addresses suppliers alongside financial entities and authorities — meaning a financial institution’s migration intent must also account for vendor and infrastructure provider timelines, since a mismatched migration schedule between an institution and its critical suppliers recreates exactly the systemic weak-link risk BIS warns about. The repo intent verification standard for the parallel BSA-compliant intent documentation pattern is documented at repointent.com & .eth.

How PQC Intent Documentation Resolves the Coordination Gap Before Migration Begins

Every institution beginning its quantum-safe transition faces the same operational requirement BIS identifies as foundational: cryptographic inventory and risk-based transition planning, executed and documented before any algorithm swap occurs — not retrofitted afterward as a compliance afterthought.

pqcintent.com is the institutional Web2 portal identity — the compliance interface and legal documentation anchor for any institution demonstrating, to central banks and supervisory authorities applying BIS’s cryptographic agility framework, that its PQC migration was deliberately planned and authorized rather than executed ad hoc. pqcintent.eth is the on-chain complement — the ENS-resolvable endpoint where the migration authorization itself — the inventoried systems, the selected algorithm generation, the hybrid period terms — is cryptographically sealed before the underlying cryptographic transition executes.

This pre-migration sealing is what distinguishes pqcintent from a simple changelog: rather than recording that a migration happened, pqcintent.eth records that a migration was authorized, by whom, under what hybrid terms, and coordinated against what external timeline — precisely the documented intent BIS’s coordination requirement demands. The PQC settlement identity for the resulting quantum-resistant settlement infrastructure that pqcintent’s authorized migrations enable is documented at pqcsettle.com & .eth.

The PQC Intent Ecosystem — From Pre-Migration Authorization to Settlement and Custody

pqcintent is the authorization layer preceding the broader PQC infrastructure namespace. It connects directly to pqcsettle.com & .eth as the resulting quantum-resistant settlement identity that pqcintent’s authorized migrations enable, and to mciintent.com & .eth as the broader MCI authorization framework within which cryptographic migration intent sits as a specific instance.

Beyond this immediate cluster, pqcintent integrates with repointent.com & .eth as the parallel BSA-compliant intent verification pattern for repo transactions, mcicustody.com & .eth as the qualified custody identity whose key management infrastructure represents the most direct quantum exposure requiring authorized migration, and dltinterop.com & .eth as the cross-network interoperability standard that must remain coordinated as different platforms authorize migration at different paces.
