Confidential Functions

Serverless that proves which code ran.

Deploy a WebAssembly function and call it over a sealed channel. Each answer carries a receipt signed by an attested key, so anyone can check the code, the node and the governance behind it.

Compute on data · Works with Verifiable Audit Log, Confidential Gateway, Data Vault & Tokenization · Same meters as every product

02 · Use case

Verifiable credit and pricing decisions

Who it's for: Lenders and insurers.

Today

When a customer, an auditor or a regulator challenges a credit or pricing decision, the lender has to show which model made it and that nobody changed the inputs or the result. Today that rests on internal logs the lender itself controls.

With Confidential Functions

The approved scoring model runs as a Confidential Function. Each application goes in over a sealed channel, the model runs inside an attested node, and the decision comes back with a receipt signed by an attested key that names the exact code and node that produced it.

What you get

  • Proof of which model version made each decision
  • Receipts anyone can check offline, without access to your systems
  • Applicant data nobody, including us, can read

03 · How it works

Four steps, all inside attested nodes.

  1. 01 · Deploy

    Publish a signed function to Calimero Cloud.

  2. 02 · Call

    Send inputs over a sealed channel from any client.

  3. 03 · Run

    The function runs inside an attested node, on your inputs only.

  4. 04 · Prove

    Every answer carries a signed receipt naming the code and the node.

04 · Built in

What it inherits from the engine.

Confidential Functions 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.
