The Sigilbase seal
About

Provable beats trusted.

Every audit log ever presented as evidence has carried an invisible footnote: trust whoever operates the database. The operator was honest, the disks were secure, nobody with admin rights had a bad quarter. Nothing in the log itself could say so.

We think a document of record should not need the footnote. A sealed letter does not ask you to trust the courier. A wax seal is not a promise; it is a mechanism. Break it and the breaking shows.

So Sigilbase is built like a registry, not a feed. Events are entered, chained to what came before, and sealed. The seal is arithmetic anyone can redo: no account with us, no goodwill towards us, no us at all, if it comes to that.

The test we hold ourselves to is simple. If you stopped trusting us entirely, tomorrow, your evidence should not care.

In practice

Retention is forever

A registry that discards entries is not one. No plan expires history, ages it out, or charges to keep it.

Ingestion never stops

History should not have gaps where an invoice went unpaid. Billing can restrict a dashboard; it never stops the record.

The verifier is open

Proof you cannot check yourself is just a claim with better typography. The verifier is open source, self-contained, and ships in every bundle.

We log ourselves

Our own operations are recorded in the same sealed ledger we sell, because a rule we exempt ourselves from is not a rule.

Sigilbase is made in the UK. It is small, deliberate, and being built now: read how the verifier works, what we claim about security, or the documentation.

Privacy

This site runs no analytics and no trackers.

It collects one thing: an email address, if you choose to join the waitlist. That address is used to send one announcement when access opens, and nothing else.

To protect the waitlist form from automated abuse we use Cloudflare Turnstile, a privacy-preserving challenge from our hosting provider; it may set a temporary cookie for that purpose and is not used to track or profile you.
