Disclosure: I’m one of the developers. SOV Network is open source (Apache-2.0), live and working today, and I’d love this community to try it and give honest feedback.

Proof of personhood usually means a company scanning your eyes with custom hardware and keeping the result. SOV Network takes a different route. Here is exactly what happens.

On your phone: you enrol with a palm scan and a live face check using your own phone’s camera. No photo of your palm or face is stored or sent anywhere. The app turns each scan into a set of numbers describing it (a feature vector, not a picture) and sends that over an encrypted link.

On the network: the node turns those numbers into a protected (cancelable) template and stores only that. Nodes compare templates for one purpose: making sure one human has exactly one account. There is no picture of anyone on the network.

Messages: end-to-end encrypted. Joining needs no phone number and no email. Nodes refuse plaintext and keep no message content; if the recipient is offline, the message waits on the sender’s own device. For delivery receipts a node keeps a small record (message ID, two pseudonymous IDs, type, time) that deletes itself after 90 days by default, and citizens can vote that down to 7.

Proven on the live network: enrolment across nodes, wallet restore, signed payments, a simultaneous double-spend refused by the nodes, cross-node messaging, the built-in exchange, the inheritance Vault and citizen votes.

Next on the roadmap: liveness verified by the nodes as well as the app, the template key split across independent operators, and more operators joining the founding servers. The whitepaper covers the full design and threat model.
