Plain-English definitions of the vocabulary behind authentic, verifiable art — the words collectors, artists, and galleries use when they talk about trust.
Provenance has its own language. Here is what the core terms mean, and why each one matters when an artwork's authenticity and history are on the line.
The documented history of an artwork's ownership, exhibition, and custody — from the moment it was created to the present day.
Provenance is the single biggest factor in an artwork's authenticity and value. A clear, unbroken record tells a buyer that a work is what it claims to be; a thin or broken record raises questions that can be expensive to answer later.
A document attesting that an artwork is genuine and recording its key facts — artist, title, medium, dimensions, and year.
A certificate is only as trustworthy as the person who issued it and the ease with which it can be checked. A certificate that cannot be independently verified carries little weight; one backed by the artist and a tamper-evident record carries a great deal.
A certificate issued by the artist directly from their studio, confirming authorship at the point of origin.
Because it comes from the source rather than being reconstructed years later, a source certificate is the gold-standard provenance record — the strongest possible starting point for the chain a collector carries forward.
A formal, recorded statement that something is true — here, a signed assertion about an artwork's authorship, ownership, or history.
The word gives Attesté its name. An attestation is only meaningful if it can be checked, which is why a credible attestation pairs a clear statement with the means to verify it.
The unbroken, ordered record of everyone who has owned or held an artwork over time.
Each ownership change is a link in the chain. Gaps weaken provenance, because an undocumented period is a period in which a work's identity cannot be vouched for. A complete chain — where every transfer is recorded and verifiable — is what separates a confident sale from a cautious one.
A unique cryptographic fingerprint calculated from a certificate's exact contents.
Change a single character of the record and the fingerprint changes completely. That property makes the hash a tamper detector: anyone can recompute it and confirm the certificate has not been altered since it was issued.
Recording a certificate's fingerprint onto the Bitcoin blockchain — via the open OpenTimestamps standard — so its existence at a given moment can be proven independently.
This is what makes a record outlast its issuer. Even if the original platform disappears, the holder of a certificate can prove it existed at the timestamped moment using only the proof file and any Bitcoin node. Independent verifiability, not platform trust, is the point.
A record built so that any alteration is immediately detectable.
Tamper-evident is a stronger, more honest claim than "tamper-proof." It does not pretend a record can never be changed — it guarantees that changes cannot be hidden. For provenance, that is exactly what matters: not that history is frozen, but that any rewriting of it is visible.
Spoken commentary about an artwork — by the artist, the gallery, or the collector — captured as a permanent recording that travels with the work.
For five centuries the knowledge behind a work lived in private letters and was lost when galleries closed and owners passed on. Talking Provenance captures it instead: a hash-chained recording, attributed to its speaker, that becomes part of the chain of custody. It preserves the context that paper records cannot.
A comprehensive, scholarly listing of all known works by an artist, used as the reference for authenticity.
Inclusion in the catalogue raisonné is one of the strongest external signals of a work's legitimacy; absence from one can be a red flag worth investigating before a purchase.
A detailed account of an artwork's physical state at a point in time — damage, restoration, wear, and any conservation work.
Condition is part of provenance. A documented condition history affects value and insurability, and protects both buyer and seller by recording exactly how a work looked when it changed hands.
An informed estimate of what an artwork is worth.
Attesté treats documented evidence as authoritative — an invoice, a professional valuation, a formal revaluation — in that order. Any experimental AI estimate is kept clearly separate and never counted in a collection's value. When it comes to worth, the receipt is king.
Attesté turns these ideas into practice — certificates you can prove, provenance that travels, and a record built to outlast any single platform.
