Label

CENTURY #31 first appears as an image under pressure. A nearly full circular field has been cut into narrow upright sections: saturated blue wedges, dark slate columns, and cream-colored arcs no longer meet where the eye expects. Fine cream and salmon lines cross these heavier forms without restoring their continuity. Reas’s project description identifies those lines as moving and provides controls for a new slicing operation or a return to the original order. These documented possibilities disclose why the still should be read as one state of an executable work, not as its terminal image.¹

Reas began the wider CENTURY body in 2012 and developed its central operation from an approach associated with Ellsworth Kelly—making a composition, cutting it into columns, and rearranging those columns. The exact Art Blocks work was released in 2021, translating that procedure into software that remains active.¹ Among the Museum’s three CENTURY works, #31 is the most compressed. Its sixteen slices turn a lucid abstract image into a contest between monument and seam: the picture survives, but only as something repeatedly interrupted.

Extended entry

The first encounter with CENTURY #31 is frontal and congested. A circular field occupies almost the entire square, but the circle cannot gather itself into a single figure. It has been divided into vertical strips whose edges behave like faults. Saturated blues rise in wedges and columns; dark slate passages block them; cream-colored forms appear as partial eyes, moons, or apertures, only to disappear behind another band. Seventeen fine lines—mostly cream, with salmon accents—cross the heavier geometry at diagonals. They seem at first to promise connection, yet their oblique trajectories make the interruption more acute. The large shapes belong to an image that has been broken; the lines belong to a space that continues across the break.

That distinction between mass and line gives #31 its particular force. The blue carries different weights: a broad plane here, a narrow upright there, a wedge caught behind cream. The cream forms are equally unstable. Some read as circular bodies; others narrow to curved edges, as if the greater part of an oculus were concealed. Because the sixteen cuts are close together, the composition has little empty space in which to recover. Its vertical rhythm is insistent—more like a bank of shutters or architectural piers than a collage laid flat. Reas’s slicing operation scrambles the image and gives the screen a shallow, contradictory depth: one section appears to stand before the next even though every mark lies on the same plane.

The live work exceeds the official still, although the Museum’s retained observation establishes only that two frames captured after a controlled wait had different hashes; no keyboard controls were activated during that session.² Reas’s own project description identifies the fine lines as moving and specifies that the audience can cut and reassemble the composition with one command and restore its original order with another.¹ Those capabilities prevent the diagonal network from becoming merely an ornamental overlay: each line is potentially an event passing through a structure that cannot wholly contain it, while the existing vertical congestion remains one arrangement among others. What looks in the still like the work’s native architecture is therefore better understood as an archive of cuts imposed upon an underlying image—an interpretation grounded in the documented operation, not in a claimed Museum witnessing of the restoration.

Reas has described CENTURY as an homage to abstraction, and its central operation derives specifically from Kelly’s practice of cutting compositions into columns and recombining them.¹ The relation is procedural. #31 takes an act once performed with painted paper and makes it a repeatable rule. Software changes the terms of that rule. A physical recombination culminates in a chosen arrangement. Here, the base composition, the current cut state, further recombinations, and continuous line movement coexist as documented possibilities of one token-bound work. The cut becomes a condition through which the image keeps passing.

CENTURY #31 resides across linked layers. Source code defines its possibilities; token-derived state supplies this blue, cream, and slate configuration; browser execution produces movement and interaction; the Ethereum token records chain identity and transfer history; the screen makes the process visible. Legal title, copyright, and Museum accession are recorded separately. The official PNG preserves an indispensable documentary view of one state within a work that remains open to another cut.

Within the 6529 Network Museum’s three-work CENTURY group, #31 establishes the pole of density and occlusion. #724 demonstrates how the same project can make open cream space and a few displaced arcs carry the composition; #401 replaces strong color contrast with grayscale overlap and a more explicitly architectural depth. #31 crowds the field until almost every passage participates in concealment. That comparison matters because the three works were not conceived by the artist as a triptych. Their value together lies in demonstrating how one procedure can produce meaningfully different spatial arguments without treating difference as a hierarchy.

The work’s title places this procedure within a long century of abstraction, but #31 refuses the familiar fantasy of abstract composition as timeless equilibrium. Its image is balanced only provisionally. The vertical slices preserve evidence of a prior arrangement, the moving lines submit the present to duration, and the controls hold another reconfiguration in reserve. What appears monumental is therefore also contingent. #31’s achievement is to make that contingency visible without dissolving into spectacle: a heavy blue-and-cream construction, carrying its own interruption as part of its form.

Title, rights, and accession review

Accession lot: 6529NM.2026.001 Decision date: 2026-08-02 Acquisition method: gift Donor credit: punk6529 Objects reviewed: seven Casey REAS Art Blocks tokens, 6529NM.2026.001.01 through .07 Institutional author: 6529 Network Museum, Registrar Decision authority: direct Museum-authorized collection authority recorded in 6529NM.2026.001.GAA-01

Determination

The 6529 Network Museum determines that the seven scheduled tokens are eligible for and accepted into the permanent collection. The donor made a full gift: the Museum accepts the donor's entire ownership interest in the tokens and every donor-held interest that is transferable with them, without consideration and without a retained donor interest. The common Ethereum transfer into networkmuseum.6529.eth, the exact contract/token schedule, the Museum's formal gift acceptance, and this reviewed title declaration together establish a sufficient title basis for accession.

This determination does not collapse token ownership into copyright ownership. The Museum owns the seven tokenized collection objects. No copyright assignment from Casey REAS is asserted or inferred. Copyright and similar rights remain with the applicable licensor or rights holder except to the extent exercised under the public license attached to each work's retained Art Blocks metadata.

The Museum accepts the ordinary residual risk that a public blockchain cannot disclose every possible private claim, security interest, incapacity, or off-chain dispute. No contrary claim, competing on-chain owner, consideration, donor reservation, or object-identity conflict is present in the reviewed record. That residual limitation is documented and accepted; it is not an open accession gate.

Evidence and title analysis

The title conclusion rests on four mutually reinforcing records:

1. The donor's instruction, treated by the Museum as a full and intentional gift of all donor-held interests in the seven tokens.
2. The formally accepted Gift Acceptance and Accession Authorization, made under the adopted Art Blocks preapproval and Donation Acceptance Policy.
3. Ethereum transaction 0xbdde33b32d4b70335b10cbd37c0b00a027844f14c900d82aa4f75b7a7b390498, whose seven ERC-721 Transfer logs deliver the exact scheduled assets to the Museum custody address.
4. The object-level chain identities, transaction log indices, and custody findings in the machine records and retained raw RPC receipt.

The transfer transaction is both custody evidence and performance of the gift. The institutional title declaration does not pretend to be a donor-signed deed; it records the Museum's reviewed conclusion from the donor's full-gift declaration, completed delivery, formal acceptance, and exact object schedule. The Museum considers that evidence sufficient for these no-consideration token gifts under its donation pathway.

The provenance record is complete for the accession event and exact receipt. Earlier token history may be enriched through continuing scholarship, but the absence of a prose ownership history for every prior wallet is not an accession blocker where the object identity, donor gift, delivery, and current custody are verified and no adverse claim is known.

Copyright and public-license analysis

All seven retained Art Blocks metadata responses identify the artist as Casey REAS and state CC BY-NC 4.0. The Museum treats those labels as object-specific source evidence that the licensed material is offered under the Creative Commons Attribution-NonCommercial 4.0 International Public License. Under the official legal code, the license grants worldwide, royalty-free, non-exclusive, irrevocable permission to reproduce and share the licensed material and to produce, reproduce, and share adapted material for noncommercial purposes. It permits all media and formats and technical modifications needed to exercise those rights. The official deed summarizes the same permissions and principal conditions.

The Museum therefore makes the following affirmative use determinations:

Commercial use is not granted by CC BY-NC 4.0 and is not approved by this review. Patent and trademark rights are not licensed. Moral, publicity, privacy, and similar rights are not broadly licensed, although the legal code contains a limited waiver or non-assertion to the extent necessary to exercise the licensed rights. The license supplies no warranty of title or non-infringement. Uses independently permitted by an exception or limitation remain outside the license's conditions.

Attribution and use protocol

Whenever the Museum shares a work or an adapted version, the accompanying credit must, so far as supplied and reasonably practicable:

• identify Casey REAS as creator and preserve any other supplied attribution party;
• identify the work and its Museum accession number;
• state CC BY-NC 4.0 and link to https://creativecommons.org/licenses/by-nc/4.0/;
• link to the source object or official project record where reasonably practicable;
• retain supplied copyright and warranty-disclaimer notices;
• state whether the Museum modified the material and preserve notice of earlier modifications; and
• avoid any suggestion that Casey REAS, Art Blocks, or another attribution party endorses the Museum or a particular use.

Recommended collection credit: Casey REAS, [title], [year]; on-chain generative software associated with an Ethereum ERC-721 token; 6529 Network Museum, gift of punk6529, [accession number]. Licensed CC BY-NC 4.0. Add Museum documentation capture or a precise change statement to derivatives and surrogates.

Registrar and risk conclusions

• Identity and authenticity: pass. Exact CAIP-19 identities, token hashes where supplied, Art Blocks project data, raw metadata bytes, and the common transfer receipt are fixed in the evidence package.
• Donor authority and title: pass with accepted residual risk. The Museum relies on the donor's full-gift declaration and completed delivery; no adverse claim or donor reservation is recorded.
• Provenance: pass for accession. The accession transfer is fully documented in the Stream-compatible provenance schedule; earlier chain history remains ordinary cataloguing enrichment.
• Rights: pass with conditions. The Museum owns the tokens, not the artist's copyright; the object-specific CC BY-NC 4.0 grant supports the noncommercial museum uses listed above.
• Compliance: pass. The gift involved no consideration, no restricted material, no personal-data payload, and no identified sanctions, dispute, or encumbrance indicator in the reviewed record. The limits of public wallet evidence are accepted rather than mislabeled as certainty.
• Curatorial case: pass. The artist profile, collection essay, and object records establish the significance of the artist, the projects, the seven works, and the collection's fit with the Museum's mission without converting interpretation into artist intent.

Accession outcome

Title, rights, identity, provenance, curatorial significance, condition, and technical evidence are sufficient for accession. The lot is approved for the permanent collection as accessioned. Long-term software preservation, dependency capture, multi-environment rendering, periodic custody verification, and future provenance enrichment remain active stewardship duties. They do not postpone the accession decision.
