Confidential Event Bus

Publish once. Each subscriber sees only its share.

Producers publish once. The bus filters and transforms each event per subscriber inside the enclave, so partners, tenants and teams each receive only the fields they are entitled to.

02 · Use case

One order feed, a tailored view for every partner

Who it's for: Marketplaces and logistics platforms.

Today

An order touches a seller, a carrier and a payment partner. Each needs some of its details and none should see the rest, so platforms maintain a separate feed and filter for every partner.

With Confidential Event Bus

The platform publishes each order event once. The Event Bus shapes it per subscriber inside the enclave, so each partner receives only the fields it is entitled to.

What it inherits from the engine.

Confidential Event Bus runs on the same confidential engine as every Calimero product, so it comes with the same proof.

Attested hardware. Clients verify the node's image before sending anything.
Sealed end to end. Nobody, including us, can read data inside a sealed node.
Signed receipts. Every answer can be checked offline, later, by anyone.
