# Daphne

Daphne is a Rust implementation of the Distributed Aggregation Protocol

([DAP](https://datatracker.ietf.org/doc/draft-ietf-ppm-dap/)) standard. DAP is

under active development in the PPM working group of the IETF.

Daphne currently implements:

* draft-ietf-ppm-dap-09

    * Prio3: draft-irtf-cfrg-vdaf-08

    * Taskprov extension: draft-wang-ppm-dap-taskprov-06

    * Interop test API: draft-dcook-ppm-dap-interop-test-design-07

The [repository](https://github.com/cloudflare/daphne) contains a number of

crates. The main one, `daphne`, implements the core DAP protocol logic for

Clients, Aggregators, and Collectors. This crate does not provide the complete,

end-to-end functionality of any party. Instead, it defines traits for the

functionalities that a concrete instantiation of the protocol is required to

implement. We call these functionalities "roles".

The remaining crates are not intended for general use:

* `daphne-server`, `daphne-worker`, `daphne-service-utils` -- Components of

  Cloudflare's backend for its DAP deployments. These crates are not intended

  for general use.

* `daphne-worker-test` -- Integration tests for `daphne` and Cloudflare's

  backend.

* `dapf` (short for "DAP Functions") -- CLI for interacting with DAP

  deployments. Some of its features are specific to Cloudflare's own

  deployment.

## Requirements

[Cap'n Proto](https://capnproto.org/) is required to build DAP.

```sh

# debian

apt install capnproto

# macos

brew install capnp

```

## Testing

The `daphne` crate relies on unit tests. To test integration with Cloudflare's

backend, run `make e2e`.
