Our Story

From distributed trust
to permanent trust.

The technology to prove facts — we have spent a decade building it. The question has changed. The core has not.

2015 — 2021

Proving ownership.
Permanently on-chain.

Who authored the software that runs the world — and who gets paid for it? We designed a protocol to record authorship on-chain and automatically distribute revenue in proportion to usage. Smart contract execution. Immutable provenance. This was our technical starting point — and the foundation of our development philosophy.

Deployed across 1,700+ projects. Recognized internationally as a pioneer in distributed trust for open source.

Generative AI raised
the next question.

We evolved the stack into a platform — so anyone could benefit from trust infrastructure without deep technical expertise. In the process, the rise of generative AI raised a new question: how do you prove that AI-processed data is real?

The technology that verified authorship
was the same technology that could prove
"this data is real" with zero knowledge.

On-chain provenance · ZK circuits · Smart contracts — a decade of accumulated capability, directly applicable to AI data integrity. From distributed trust to permanent trust. The core is consistent.

THE NEW CONTEXT

From public infrastructure —
the connections keep expanding.

The platform was first deployed in public infrastructure maintenance. Citizens contribute to upkeep and receive appropriate compensation — operating continuously since 2025. The AI economy now demands the same trust layer. As AI agents autonomously contract, order, and settle, what they need is exactly what we have built: verified identity, proven facts, authorized permissions.

This technical foundation is what Lemma Oracle is built on.

Flagship Product

Lemma —
Permanent trust,
implemented.

The AI agent economy is real. Lemma provides the indispensable foundation — verified identity, proven facts, and authorized permissions. A decade of distributed trust, evolved into permanent trust for the AI era.
