Your collection,
on the record.
Every figure attested. Every document hashed. Every valuation sealed and anchored to a public blockchain. A record built for the moments that test it — the claim, the loan, the estate. Quiet, exacting, and entirely yours.
A catalogue raisonné for a collection of one.
Everything a registrar keeps for a museum — applied to what you own, and only ever seen by you.
Every number is traceable.
Acquisition cost, insured value, break-even, net proceeds — computed from signed cost records, never typed into an editable field. A figure that can change without a trail is not a figure a counterparty will trust.
Every document is hashed.
Files entering the Registry are fingerprinted with SHA-256 and linked permanently to the records they support. The hash doesn't change unless the document does. Anyone can check.
Every valuation is sealed.
Signed, timestamped via OpenTimestamps, anchored to a public blockchain — verifiable against our published key.
Named for the conversation, not the feature.
We do not certify authenticity. We prove reproducibility, tamper-evidence, and honest grading — and we say so.
The Registry prices and attests. It never operates a market, takes a stake, or charges a transaction fee.
What doesn't happen here.
When the data can't support a figure, the Registry refuses to produce one. A red readiness gate returns a refusal notice — not a report with caveated numbers.
Gap not computed — insufficient comparables (3 on file)
Most systems store data. The Registry records how it knows what it knows.
Asserted by a person; no external document of record.
Computed by the valuation engine from recorded inputs.
Backed by a source document; the locating quote was verified verbatim.
Extracted from a source document; not verbatim-verified.
Recorded as unbacked: no source, no assertion of record.
No attestation on record — this fact was written outside the attested path.
