Use case · Verified Work Certificates

Proof that ends the invoice argument

A queried invoice costs you a week of assembling screenshots. Finalize it here and it mints a signed, timestamped, WORM-anchored certificate the client verifies on a public page.

What makes a certificate worth showing a client

Every line here opens the screen it happens on. Judge the job on what it puts in front of a manager, not on the sentence describing it.

How it works

From a work edge to a link that verifies itself

  1. 1

    Capture the work edges

    Shipped work, commits, tickets, documents, active-tab URLs, is recorded as it lands, with integrity signals raising or lowering the tier of the resulting record.

  2. 2

    Finalize the invoice

    Approved hours and delivered outcomes roll into an invoice. Finalizing it is the event that seeds a Verified Work Certificate.

  3. 3

    Sign, timestamp and anchor

    The certificate is Ed25519-signed, stamped by an RFC-3161 authority and written to WORM storage, then hash-chained into the audit trail.

  4. 4

    Share a link that verifies itself

    Send the URL, embed the widget, or hand over a bundle to paste into the verifier. Whoever receives it checks it without asking you for anything.

Screenshots in a slide deck vs. a certificate that verifies itself

workmonitor.vsScreenshot evidence

  1. What the client receives

    With WorkMonitor

    A URL that returns a cryptographic verdict, computed by the page rather than asserted by you.

    Screenshot evidence

    A PDF of screenshots and a spreadsheet, both of which you produced and both of which they have to take on faith.

  2. Tamper resistance

    With WorkMonitor

    WORM storage, an RFC-3161 timestamp and a hash-chained trail, a change breaks the chain and the verifier says so.

    Screenshot evidence

    An image can be cropped, retouched or reordered, and a spreadsheet cell can be typed over.

  3. What proving it costs you

    With WorkMonitor

    Selective disclosure reveals the fields you choose. The record is built from work edges, so there is no screenshot to hand over in the first place.

    Screenshot evidence

    Proving the work means showing the screen, which puts the client’s own data, and everything else that was open, into a file you now have to look after.

  4. Who has to be trusted

    With WorkMonitor

    Nobody. The signature is checkable against a published JWKS key, and BYOK means the key can be yours.

    Screenshot evidence

    The vendor, the account manager, and whoever assembled the deck.

  5. Where it lives

    With WorkMonitor

    A permanent verifier URL on your own domain, embeddable in your portal and still checkable long after the project closed.

    Screenshot evidence

    An email attachment that ages out of the thread and cannot be re-verified next year.

  6. Placing the same people again

    With WorkMonitor

    Worker-owned credentials, in beta, let a contractor carry a co-signed, publicly verifiable history into the next engagement.

    Screenshot evidence

    The evidence sits in your files and stops there, so every new engagement starts the credibility argument from nothing.

The status meeting, already written

Status is normally assembled by asking. Here it is already: hours, activity, attendance and risk on one board, for one person or the whole company. Set the thresholds once and it tells you who needs you.
