Digital EUR – Do Not Accumulate

Part of Do Not Accumulate, a net.art series of forty-two imagined Central Bank Digital Currencies inscribed on Bitcoin. The Digital Euro is a single, self-contained HTML banknote rebranded as a currency of the European Centralization Authority. Twenty-one editions exist, each programmed to lose its value across a twenty-one-month demurrage cycle.

Visual references. Drawn entirely in vector graphics, the bill subverts the design language of the real Euro notes. The architectural windows, doors, and bridges that anchor every Euro series give way to a sky of clouds: a navy, scarlet, and pale cloud cluster floats over a yellow sun, surrounded by EU stars that have lost their orderly ring. The honeycomb security pattern returns as a translucent grid in the background. The left margin carries vertical labels of “European Central Bank” written in the languages of the Eurosystem (BCE, EBC, EKB, ESB, EKT, EKP, EZB, ЕЦБ, ECB). The right margin carries a CB DC wordmark and a column of coloured dash bars. DIGITAL EURO runs in three scripts at the centre, Latin, Greek (EYPΩ), and Cyrillic (ЕВРО), and a discreet 2025 MLO.art watermark anchors the lower-left corner.

The propaganda machine. As each edition advances through its cycle, the bill becomes its own propaganda machine. System warnings, adjustment notices, and demurrage countdowns surface on the surface of the note, selling the controls they impose. The recurring lines shift in tone across the cycle, from Physical currency is being retired to provide a faster, safer, and more inclusive payment experience in the early months, to Accounts may be placed in a temporary review state to protect network integrity later on. Surveillance, spending limits, and the erosion of privacy are recast as features and convenience.

Architecture. The work lives on Bitcoin as a recursive ordinal. A four-layer architecture (a shared artist layer, shared assets, the Digital Euro currency layer, and twenty-one individual edition inscriptions) reconstitutes each note on demand, fully on-chain, with no external dependencies. Cornerstone editions (1 and 21) are inscribed on rare satoshis whose blocks were mined on real EU CBDC policy milestone dates: the ECB’s introduction of negative interest rates (2014), the European Council’s adoption of eIDAS 2.0 (2024), and the closing of the ECB’s preparation phase (2025). The substrate carries the policy timeline alongside its imagined consequences. The title encodes the rule: D.N.A. spells Do Not Accumulate, and demurrage is its inner code. A permanent medium records a currency built to expire.
