Proof of Art
Inside the record behind an NEC Digital Art Collectible.
The artwork comes first. But its history doesn’t have to rely on trust alone.
What does “proof” actually mean?
A record that can be checked — not just believed.
For an NEC Digital Art Collectible, proof begins with evidence. The artwork, its edition, its creator and the important records associated with it are identified in ways that can later be checked. Some of that evidence is human-readable. Other parts are machine-verifiable. Together, they create something more useful than a claim of authenticity: a trail that can be examined.
Trust is useful. Evidence is better.
THE DIGITAL FINGERPRINT
SHA-256 — a fingerprint for a file.
Change the file. Change the fingerprint.
Important files within an NEC Digital Art Collectible are given cryptographic fingerprints using SHA-256. SHA-256 reads the contents of a file and produces a 64-character fingerprint. If the file remains exactly the same, the same fingerprint can be produced again.
Change even a tiny part of the file and the fingerprint changes.
That allows a file retrieved years later to be compared with the fingerprint recorded when the collectible was created.
A fingerprint does not prove who created the artwork.
It answers a different question:
Is this exactly the same digital file that was recorded?
Identity, edition information, provenance and collector terms provide the context around it.
Same file, same fingerprint.
Change the file, change the evidence.
WHERE THE RECORD LIVES
Where does the record live?
Not in just one place.
An NEC Digital Art Collectible is deliberately designed so that its history does not depend entirely upon the Nathaly Ellen Celia website, one marketplace, one computer or one company remaining online.
Different parts of the architecture perform different jobs. Ethereum provides the public blockchain identity and transaction history. Cryptographic fingerprints identify exact digital files. Metadata connects the blockchain record to the artwork and its supporting information. IPFS provides content-addressed identifiers and independently hosted copies. Arweave provides an additional long-term preservation route for key material.
The artist’s archive retains the original files and supporting documentation.
No single component needs to tell the whole story.
The strength comes from the records agreeing with one another.
Different systems. One history. Fewer single points of failure.
BLOCKCHAIN
What is actually on the blockchain?
Not the artwork pretending to be a database entry. The record that identifies it.
The artwork itself does not need to be stored inside Ethereum. Instead, the blockchain provides a durable reference point for a particular collector edition.
That record can include its smart contract, Token ID, ownership and transfer history, and a reference to the metadata associated with the collectible.
The blockchain is extremely good at preserving small, verifiable records.
It is not supposed to behave like an ordinary hard drive.
The artwork, metadata, cryptographic fingerprints and preserved files perform different jobs around that blockchain identity.
The blockchain records the collectible. It does not replace the artwork.
METADATA
So how does the blockchain know what belongs to what?
Metadata connects the record to the artwork.
A blockchain token can identify a particular collector edition, but it also needs structured information explaining what that token represents.
That information is called metadata.
For an NEC Digital Art Collectible, metadata can identify the artwork title, creator, edition, collector licence and references to the artwork files and supporting provenance.
It acts as a machine-readable map between the blockchain identity and the wider record surrounding the artwork.
The metadata is not the artwork.
It explains what the blockchain record points to.
The blockchain provides the reference. The metadata gives the reference meaning.
IPFS + ARWEAVE
So where does the artwork actually live?
Usually, not on the blockchain.
NEC Digital Art Collectibles use independent preservation systems rather than asking one ordinary website to carry the entire history of an artwork.
Two important parts of that architecture are IPFS and Arweave.
IPFS identifies digital material by its content.
When material is added using the appropriate IPFS process, it receives a Content Identifier — a CID — derived from that content. Change the underlying content and the identifier changes.
Arweave approaches preservation differently. It is designed around long-term storage of digital information.
They therefore perform complementary jobs within the NEC architecture.
IPFS helps identify exact content. Arweave provides another independently maintained preservation route. The artist’s archive provides another. And Ethereum helps connect the collector edition to its wider record.
Permanence is a system, not a location.
NEC DCL 001 — Orbiting Consciousness
The architecture in practice.
Orbiting Consciousness is the first NEC Digital Art Collectible by Nathaly Ellen Celia.
It is a one-of-one digital collector edition built around a purpose-built ERC-721 smart contract on Ethereum Mainnet.
The collectible has its own blockchain identity, cryptographic fingerprints, preserved digital files, metadata, provenance documentation and collector licence.
What the preceding sections describe in principle, NEC DCL 001 demonstrates in practice.
This is where Proof of Art stops being theoretical.
CANONICAL IDENTITY
Canonical collector edition
One artwork. One edition. One identifiable blockchain record.
Artwork: Orbiting Consciousness
Artist: Nathaly Ellen Celia
Collection: NEC Digital Art Collectibles
Edition: 1 of 1
Network: Ethereum Mainnet
Token standard: ERC-721
Token ID: 1
Smart contract
0x31c4e14288879a523ad5aa46179d112e62f85361
Collector licence
NEC-DCL-COLLECTOR-1.0
Contract royalty specification
5%
The combination of network, smart-contract address and Token ID identifies the canonical blockchain collector edition.
A name can be copied.
An image can be copied.
The canonical record is much harder to impersonate.
The corrected production contract, Ethereum Mainnet identity, Token #1 and 500-BPS/5% royalty specification are preserved in the final 001 record.
001 FINGERPRINTS
The fingerprints of Orbiting Consciousness
The artwork can identify itself.
The canonical master artwork has the SHA-256 fingerprint:
99f602ded8039a44a859bb83c669256180778a0e7dbf56f5772204318903e41c
The accompanying motion artwork has its own SHA-256 fingerprint:
3cb707dd88feca2ae71e3e49c30d1c4e4fbe4f6827c5793203dcf6df68895516
These values allow retrieved files to be checked against the exact files recorded for NEC DCL 001.
File names can change.
Folders can change.
Websites can change.
A changed file cannot quietly keep the same SHA-256 fingerprint.
METADATA
The production metadata
The bridge between Token #1 and the artwork.
Token #1 points to the production metadata through IPFS:
ipfs://bafkreiene5yik6azlcvz6f2c5s4ecqirn6ve425olbfeng35dxgv4jtpym
The metadata connects the collector edition to Orbiting Consciousness, Nathaly Ellen Celia, its artwork, motion work, collector licence and supporting records.
It provides the structured information needed to understand what Token #1 represents.
The token identifies the edition.
The metadata connects that identity to the artwork.
PRESERVED FILES
Preservation beyond one location
Several routes back to the same evidence.
The master artwork and supporting records do not depend upon one storage location.

These routes do not compete with one another.
They strengthen one another.
Those exact identifiers are in the authenticated release manifest.
PIÑATA / OFFLINE TEST
But what if the artist’s computer is switched off?
We tested that.
IPFS can identify content, but identification alone does not guarantee that somebody continues storing it.
NEC DCL 001 therefore uses independently hosted IPFS copies through Piñata as an additional preservation route.
During release verification, the project’s own local IPFS node was deliberately taken offline.
We then remotely retrieved:
The canonical master artwork
The motion artwork
The full collector licence
The production metadata
The provenance record
Each retrieved file was checked against its expected file size and SHA-256 fingerprint.
5 files tested.
5 files matched.
This demonstrated that the release material could be retrieved independently of the artist’s computer and checked against the evidence recorded for NEC DCL 001.
Piñata is not the provenance.
It is one route to it.
IPFS provides content-based identifiers.
Arweave provides another preservation layer for key material.
Ethereum records the blockchain identity and history.
The artist’s archive preserves the originals.
The strength lies in the records agreeing.
Permanence is not one place surviving forever. It is the evidence surviving the places.
All five daemon-off retrievals were recorded as part of the NEC DCL 001 release verification.
CAN SOMEBODY COPY IT?
So can somebody just copy it?
The file can be copied. The history does not come with it.
A digital image can be copied, downloaded or displayed elsewhere.
Blockchain technology does not pretend otherwise.
An exact copy may even have the same cryptographic fingerprint because its digital contents are identical.
What that copy does not automatically inherit is the recognised NEC collector edition surrounding it:
the smart contract,
Token ID,
edition information,
ownership history,
collector licence,
metadata,
and supporting provenance.
The fingerprint answers:
Is this the same file?
Provenance answers:
What is this file?
Copying the image does not copy the provenance.
WHAT THE COLLECTOR OWNS
What exactly does the collector own?
Ownership is specific. Copyright is separate.
The collector owns the specific digital collector edition represented by its blockchain record.
Control of the token can move between wallets and its ownership history can continue from one collector to another.
But ownership of the collectible does not mean ownership of Nathaly Ellen Celia’s copyright.
The artwork remains the intellectual property of the artist.
The rights accompanying lawful ownership are defined by the NEC collector licence associated with that edition.
Owning the collectible establishes which edition is yours.
The licence establishes what you may do with it.
Copyright establishes who owns the underlying creative work.
The collectible can change hands. The authorship does not.
SMART CONTRACT
So what is the smart contract actually doing?
Rules written into the collectible.
A smart contract is a program deployed to a blockchain.
For NEC Digital Art Collectibles, it provides the underlying rules that allow a collector edition to exist as a distinct blockchain asset.
NEC DCL 001 uses a purpose-built ERC-721 smart contract.
Its programmed behaviour governs the collectible’s blockchain identity and the mechanisms surrounding its issuance, ownership and transfer.
Once deployed, that contract does not live on this website.
It exists independently on Ethereum.
That distinction matters.
The collectible should not depend upon somebody remembering what its rules were supposed to be.
The website explains the collectible. The smart contract executes its rules.
BLOCKCHAIN HISTORY
Follow the blockchain history
A provenance trail you can inspect for yourself.
The production NEC DCL 001 smart contract was deployed on Ethereum Mainnet.
Token #1 was then minted.
It was subsequently transferred into the dedicated NEC collection wallet.
Those events are part of Ethereum’s public transaction record.
They do not have to be taken on trust.
They can be inspected.
HISTORY SHOULD NOT BE ERASED
What can change — and what cannot?
History can grow. It should not be rewritten.
A provenance system becomes more useful when it preserves inconvenient history as well as successful history.
An earlier NEC DCL 001 deployment exists as superseded historical blockchain evidence.
It is not the canonical production collector edition offered for acquisition.
It has not been erased or disguised.
It remains part of the project’s history.
The recognised production collectible is:
NEC DCL 001 — Orbiting Consciousness
Ethereum Mainnet
Contract
0x31c4e14288879a523ad5aa46179d112e62f85361
Token #1
Adding a corrected record should not require pretending an earlier event never happened.
Change should leave a trail.
Technology can change.
History should accumulate.
WHAT IF OPENSEA DISAPPEARS?
What if a marketplace disappears?
The storefront can disappear. The record should not.
A marketplace is a way to view, acquire or transfer a collectible.
It is not the collectible itself.
NEC DCL 001 can still be identified through its Ethereum smart contract and Token ID independently of OpenSea.
Its metadata, fingerprints, preserved files, licence and provenance records exist outside the marketplace.
If one interface disappears, the underlying blockchain record does not disappear with it.
Another compatible interface may later read the same public record.
A marketplace is an access point.
The provenance is designed to outlive the storefront.
PERMANENCE
What does “permanent” actually mean?
Not indestructible. Designed to survive change.
Nothing digital should be described as magically indestructible.
Websites can disappear.
Companies can close.
Storage systems can change.
Technology can be upgraded, replaced or abandoned.
NEC therefore does not ask one website, company, blockchain or storage location to carry the entire history.
If one route becomes unavailable, other evidence should remain capable of identifying the collectible and helping reconstruct its record.
The objective is not to freeze technology in time.
It is to make the history increasingly difficult to lose.
Permanence is not one place surviving forever. It is the evidence surviving the places.
So what are you actually trusting?
As little as possible.
No provenance system can remove trust completely.
There will always be things that begin with the artist: the creation of the artwork, the decision to release it and the original information recorded about it.
The aim is to reduce how much of the story must continue to be believed simply because somebody says it is true.
Blockchain records, cryptographic fingerprints, metadata, licences and preserved files provide different pieces of evidence.
Those pieces can be compared.
The purpose of the architecture is not to make the artwork complicated.
It is not to make technology the centre of the experience.
It is to make the history surrounding a digital artwork harder to lose, harder to confuse and harder to rewrite without leaving evidence behind.
You should not have to believe the story because we tell it well.
Follow the evidence.
The artwork comes first.
The evidence is there for anyone who wants to look behind it.
