pienidz

Pienidz is a fictional digital currency concept used in worldbuilding and speculative fiction to illustrate a decentralized monetary system within a self-contained economy. It is typically depicted as the currency of a network of city-states and communities in a fictional archipelago.

The term pienidz derives from the constructed language of the Pienids, a culture described in Halin Vosk's novella The Ivory Ledger (2018). The word is presented as the plural form of pienid, the unit coin, within the fictional lexicon.

In common depictions, pienidz runs on a distributed ledger shared by participating polities. Validation is performed by a rotating panel of guardians rather than miners, and minting occurs through a social-contract mechanism tied to compliance with a charter. The supply is capped and adjusted by a governance council composed of representatives from member communities, with mechanisms intended to align incentives and prevent hyperinflation.

Pienidz is used for daily trade, taxes, and rituals within the in-universe economy. Its value is described as being anchored to a basket of goods and services, with some narratives featuring a universal basic income funded by periodic dividends from a central reserve. Transaction costs and social sanctions are sometimes employed to discourage hoarding and promote circulation.

Reception and usage: The currency appears across novels, tabletop campaigns, and design exercises in economic theory and governance. Critics use pienidz to explore questions about digital cash, sovereignty, and the social implications of currency systems, while writers note its utility as a flexible tool for worldbuilding and narrative tension.
