Document & credential timestamping
A university anchors the hash of a diploma at issuance. Years later, an employer confirms the exact document existed on that date — without contacting the registrar.
Verifiable existence at a point in time.
Use cases
One primitive. Two economies.
Provable, unalterable, enduring data is the shared requirement beneath both the digital economy and the AI economy. Here is what it unlocks in each.
Digital economy
Digital economy
When records must outlast their hosts and survive scrutiny, anchoring to Bitcoin turns 'trust us' into 'verify it yourself.'
Provenance & anti-counterfeiting
A manufacturer inscribes a product's origin record at the factory. Every party down the supply chain checks the same unalterable entry.
Unalterable origin, independently checkable.
Verifiable audit logs
A fintech anchors a daily digest of its append-only logs. Auditors detect any retroactive edit because the anchored hash would no longer match.
Tamper-evidence anyone can confirm.
Permanent publishing
A journalist inscribes an investigative report in full. It cannot be quietly pulled, edited, or de-indexed by any host.
Censorship-resistant permanence.
Fully on-chain collectibles & assets
An artist inscribes the complete artwork — not a link to it — so the asset survives as long as Bitcoin does.
Self-contained, no broken links.
AI economy
AI economy
Autonomous systems act on data and on each other's outputs. Provenance and attestation, anchored to Bitcoin, give that activity an audit trail no party can quietly rewrite.
Training-data provenance
A lab fingerprints each dataset version and anchors it before training. The exact corpus behind a model becomes provable after the fact.
Provable dataset lineage.
Model attestation & versioning
On release, a team inscribes the model's weight hash and metadata. Downstream users confirm they are running the attested version, unmodified.
Authentic, versioned model identity.
Decision & inference logs
An autonomous agent anchors a digest of the inputs and rationale behind a high-stakes action, before it acts.
Accountable, after-the-fact auditable decisions.
Content authenticity
A camera or pipeline anchors a capture hash at the moment of creation, distinguishing originals from later synthetic edits.
Origin distinguishable from synthesis.
Agent accountability
Agents verify each other's anchored attestations before trusting an output — establishing provenance between machines.
Machine-to-machine trust, anchored to Bitcoin.
