Semantos — a shared layer beneath your apps where every fact is one sealed record that can't be faked, copied or quietly changed.

The engine under our work

One true record, beneath all your apps.

Semantos is a shared layer that sits under your software. Every fact becomes a single sealed record that carries its own proof, moves freely between systems and organisations, and can't be faked, copied, or quietly changed — guaranteed by maths and by Bitcoin, not by trusting a platform.

Today, the truth is scattered

Nobody knows what's real

The same job is a ticket in one tool, a draft in another, an email in an inbox, a notification on a phone — each a different version, none of them canonical.

Meaning is lost at every handoff

"Urgent — no hot water, fix before 5pm" becomes a status code in a database. Who agreed what, and who approved the spend, dissolves at each step.

Your data lives in someone else's house

Every platform you adopt owns your records in its model, not yours — and becomes the chokepoint. Access ends when the subscription does.

Every integration you build and every audit you reconstruct after the fact is a symptom of missing infrastructure. The real question isn't which platform to trust — it's what a layer below the platforms would look like.

What it is

Not another app. Not another platform. A common foundation your applications are built on — owned by no platform, available to everyone who takes part in a workflow. Adopt it once and the integration, trust and reconciliation work stops being rebuilt from scratch every time.

How it works, in plain terms

Every fact is a sealed recordthe cell

One small, tamper-evident format that's identical everywhere — on a phone, on a server, on the wire, and on-chain. Each record is chained to its history, so any change is visible.

Records behave like physical thingslinearity

A paid invoice can't be silently un-paid. Money can't be spent twice. A certificate can't be quietly dropped. The system enforces this itself — and Bitcoin enforces it again at settlement.

The rules travel with the datapolicy engine

What's allowed is attached to the record, not locked inside one company's server. So the same guarantees hold no matter which app or party is handling it.

Plain language in, the right records outin Oddjobz today

In our live Oddjobz business, a plain message — "tenant has no hot water" — becomes a job, a quote and, when approved, an invoice sealed on-chain. No forms, no custom integration code.

Identity that fits real life

You're not one thing. The same person acts as their company, a co-op they belong to, or themselves — and what they can see and do follows the role they're acting in, automatically.

Roles, not logins

Access follows the hat you're wearing — company, cooperative, or individual.

Works in any browser

Sign and pay in a normal browser tab — no extension or plugin required.

Runs anywhere, proves itself anywhere

Tiny and portable

The same small engine runs in a browser tab, on a server, or on a $5 sensor.

No trusted middleman

Records carry their own proof, so they can travel over anything without a central server vouching for them.

Settled on BSV for cents

Works alongside your existing systems; final settlement is anchored on BSV for a fraction of a cent.

Why you can trust it

Most software asks you to trust that the code is correct. Semantos doesn't. Its core safety rules are mathematically proven — checked by a formal proof system, not just tested — and Bitcoin enforces the same rules again at settlement. Two independent guarantees that a record can't be faked, double-spent or quietly undone.

What it already powers

It's not theory. The same engine runs a real business and these on-chain systems today.
