About this app

Common Source
A self-sovereign blockchain-based identity that puts you in control. Create your account in seconds. No email, no password, no server. Your identity stays on your device.

A network of networks
- Common Source orchestrates regional food systems for farmers, cities, and citizens with one portable identity across the entire ecosystem.

How it works
- Account creation. A keypair is generated locally on your device. No email, no password, no server involved.
- Build your profile. Add only what you choose: name, location, description.
- Join any network. Carry the same identity across different networks. You control what each network can see.

Core principles
- Identity ownership. Your profile is generated and stored locally, with no server backup.
- One login, every network. The same blockchain-based identity works across multiple regional food networks.
- You decide what to share. Networks must request permission for each piece of data.

Built for trust
- A fair price for the farmer
- A verifiable choice for the consumer
- Personal data stays on your device. Only cryptographic commitments touch the ledger.
One portable blockchain-based identity across every network. Fully yours.
