Flowsta Identity DNA

What is Flowsta Identity DNA and what is it for?

Flowsta Identity DNA is the Holochain DNA behind Flowsta's identity layer: it holds each user's W3C decentralized identifier and the attestations that show two agent keys belong to the same person. It exists so an identity can be registered once on a public network without exposing who the person behind it is, and checked by any application that joins that network.

The Flowsta Identity DNA is documented as the public half of a two-DNA design: this DNA is the record anyone can read, while a companion private DNA keeps everything encrypted on the user's own device. Its early versions stored more than they do now. The maintainer's own history records an email hash and a display name being taken off the public network as personally identifying, and later the profile picture and the flag marking that a picture was set.

What remains on the public network is deliberately thin. A profile carries a W3C decentralized identifier and the timestamps for when it was created and updated, and nothing else. Because agent keys are random cryptographic identifiers, a profile can be looked up and checked without disclosing who wrote it. The same design lets a person prove that two different app identities are theirs, through attestations any participant on the network can verify.

For a Holochain developer the practical example is identity linking. An application asks the user's Flowsta Vault for a link; the Vault signs the request once the user approves it; the application then commits that attestation to its own DHT with a zome call, so other participants can check the link without calling Flowsta. The integration steps are at docs.flowsta.com/holochain/agent-linking, and the DNA source is in the project repository.
