A network of networks

A fair price for the farmer.
A verifiable choice
for the consumer.

Common Source orchestrates regional food systems that work for farmers, cities and citizens — one portable identity across every network in the ecosystem.

Self-sovereign identity No email, no server iOS & Android
Common Source welcome screen — your identity lives on this device only
Three principles

Identity that belongs to the person carrying it.

01

Stays on your phone

Your profile is generated on this device, stored on this device. No server holds it. No company can lose it for you.

02

One login, every network

Join Cities Leading Food Production, Nieuw-West, EU4Advice, Utrecht, or a network we haven't met yet — the same identity travels with you.

03

You decide what to share

Networks must ask before reading anything. You approve each request, one field at a time, every time.

How it works

Three steps. No account required.

A profile in under a minute, and you can use it anywhere Common Source is supported.

Same identity in Utrecht, in Amsterdam, in a researcher's portal — you decide what each one sees.

Networks in pilot

Real networks. Real names. No abstractions.

Common Source isn't a logo on a slide. It's the connective tissue between cooperatives, cities and research projects that are already in the ground.

Cities Leading Food Production

municipal · EU

Twenty-three European cities coordinating procurement, growers and citizen-led food councils.

EU4Advice

research · advisory

Cross-border knowledge exchange between farm advisors. Verifiable contributions, automatic rewards.

Nieuw-West

amsterdam · resident

Neighbourhood-scale food cooperative in Amsterdam West. Local growers, local kitchens, local price.

Utrecht

municipal · pilot

A city-wide rollout of transparent supply tracking from soil sensor to school cafeteria.

The honest part

Your recovery phrase is the only way back in.

If you lose your twelve words, the account is gone. We can't reset it, because we don't hold it. That's the trade — and it's the trade that makes the rest of this work.

Most "identity" products keep a copy of you on their server so they can let you back in when you forget your password. That copy is also what gets leaked, sold, subpoenaed, or quietly trained on. Common Source doesn't keep that copy.

Treat the phrase like cash. Write it on paper. Put it where you keep important paper. If you'd lock it in a drawer, lock it in a drawer.

Questions

Plain answers.

Still not sure? Write to us.

What does "decentralised food governance" actually mean?
It means the people growing, distributing, regulating and eating the food are the ones running the network — not a platform sitting in the middle taking a cut. Common Source provides the rails; the cooperatives and cities provide the rules.
Why is this built on a blockchain?
Four reasons. Identity has to be portable across networks. Data integrity has to hold from soil sensor to consumer. Payments need to settle without an intermediary skimming. And rewards need to be programmable — automatic, not negotiated. BSV gives us all four at a per-transaction cost that works for a head of lettuce.
Do I need a crypto wallet to use this?
No. The app is the wallet. You don't see addresses. You see networks you've joined and requests waiting for your approval. The cryptography is underneath, not in the way.
Who runs Common Source?
Common Source is stewarded as an open project together with the partner networks listed above. Governance is documented and on-chain.
What does it cost?
The app is free to download and use. Networks set their own participation terms. Transactions on the underlying ledger cost fractions of a cent, paid by the network operator, not by you.
Is my data on a blockchain?
No. Your personal data lives on your device. Only the cryptographic commitments — proofs that something is true without revealing what — touch the chain. Your name, your address, your purchase history: none of it.
Take it with you

One identity. Every network.
