A Weapon Too Terrible To Use

CONFIDENTIAL (RED) / EYES ONLY GLITTER TARNISH
EXCHEQUER INTERNAL

Welcome, operative of the Imperial Exchequer.

If you are reading this document, it is because you either have need to know for, or have independently discovered, the weaponizability of the currency validation system.

To recap: the modern esteyn possesses full verifiability against counterfeiting, since every individual currency unit possesses an embedded cryptographic signature incorporating its denomination and serial code. This applies to both physical currency, in which this signature is embedded in v-tag format, and to money of account; an esteyn-denominated account must record not only the quantity of money contained therein, but the unique cryptographic signatures of each esteyn-unit stored. In either case, such units can be verified as genuine by an authentication exchange conducted across the Imperial Banking & Credit Weave.

We retain the ability to generate new cryptographic signatures and to invalidate old signatures at will. This latter facility is used principally by the Office of the Mint when replacing worn-out, damaged, or lost physical currency, and by the Office of Currency and Values, when adjusting the total money supply (i.e., to draw down the money supply, the OCV invalidates the signatures of selected esteyn-units presently in the general account of the Exchequer).

The realization you may have come to is simply that we do not require possession of a group of esteyn-units in order to invalidate their signatures; we merely require their serial codes. As such, we can invalidate any quantity of esteyn, anywhere in the galaxy “by remote control” – revoking its status as legal tender and a store of value, and rendering it useless in transactions anywhere in the legitimate economy.

This capability has never been used.

It is conceivable that one day we may receive an executive order to weaponize this functionality for use against terrorists, slavers, rogue polities, criminal organizations, or others misusing Imperial currency. It is, naturally, far more flexible than seizure of accounts (possible in Imperial banks or those of close allies only) or transactions (which requires that said transaction clear directly through the Imperial Banking & Credit Weave) inasmuch as it can revoke any esteyn-units, even those instantiated as physical cash. For these reasons, we retain the technical capability.

However, the projected economic effects of exercising this capability would be very severe. Much of the galactic market can be modeled as imperfectly trusting, irrational, and/or panic-prone, and the use of this capability would undoubtedly lead to an immediate external market crash, extending into a medium-to-long term depression. As a matter of policy, the Exchequer considers this a circumstance to be sedulously avoided.

As a final note, while the existence of this capability is not a secret (note the classification level of this document) since it is readily comprehended by anyone who makes a sufficiently adequate study of the relevant public protocol definition documents, the Exchequer chooses not to advertise its existence widely in the sight of economic knowlessmen. As such, you should consider it sensitive data, not for casual public dissemination.
