Technology opens what CAN be. The market chooses what SHOULD be. Regulation carves what MUST be — then the market asks technology for the next CAN.
Provenance has long only marked the points regulation demands. But no matter how many points you stack, you never draw the line. Continuous provenance — proving the line, not the points. That is the next CAN.
prove your data into line.
The reference implementation of continuous provenance.
provin makes continuous provenance run. At every boundary where data is received or transformed, it records — in a tamper-evident form — who received what, what was done to it, and what was passed on — and binds each record to the one before it into a single verifiable line.
Anyone can verify that line independently, across organizations — without a central trust authority. A convincing point is cheap to forge; a connected line is not — it would take the keys of every boundary it crossed and consistency with records already held downstream.
- ✅ Authenticity and continuity of the record: each link is signed, and the chain is unbroken and independently checkable.
- ❌ Not the truth of the contents. If a source records a wrong value, the value stays wrong even when the line is complete.
- It complements existing provenance standards rather than competing with them — it fills the layer of continuity between boundaries that they leave out of scope.
provin is the reference implementation of dPLaaX — the open protocol that defines continuous provenance.
