A network of networks

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

Common Source connects farmers, cities and citizens in regional food networks. You create one profile on your phone and use it in every network you join.

One profile for every Living Lab and partner network. No email address, no account on a server.

Three principles

Identity that belongs to the person carrying it.

01

Stays on your phone

Your profile is created and stored on your phone. There is no copy on a server, so nobody else can lose it or leak it.

02

One login, every network

Join Cities Leading Food Production, Nieuw-West, EU4Advice or Utrecht with the same profile. New networks can be added as they come on board.

03

You decide what to share

A network has to ask before it can read anything from your profile. You see each request and choose what to approve.

How it works

Three steps to get started, no sign-up needed.

It takes about a minute, and the profile works in every network that supports Common Source.

01 - Create account

Tap once to get started

The app creates your keys on the phone itself. You don't need an email address or a password, and nothing is sent to a server.

02 - Your dashboard

Everything in one place

Contacts, messages and Living Labs are all on one home screen.

03 - Use anywhere

Use it across networks

Use the same profile in Utrecht, in Amsterdam or in a research partner's portal, and choose what each one can see.

Networks in pilot

The networks already on board.

Cooperatives, cities and research projects, each running their own network on Common Source.

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 for you, because we never had a copy. That is the price of keeping your identity in your own hands.

Most identity services keep a copy of your details on their servers so they can reset your password. That same copy is what ends up leaked or sold when things go wrong. Common Source doesn't keep one.

Write the phrase down on paper and keep it somewhere safe, the same way you would a passport or the deeds to a house.

Questions

Common questions

Not covered here? Write to us.

What does "decentralised food governance" actually mean?
The people who grow, distribute, regulate and eat the food run the network themselves, rather than a company in the middle taking a cut. Common Source provides the shared infrastructure, and each cooperative or city sets its own rules.
Why is this built on a blockchain?
A few reasons. Your identity needs to work across many independent networks. Records about produce need to stay intact from the farm to the shop. Payments need to settle without a middleman taking a percentage, and rewards need to be paid out automatically. BSV handles all of this at a fraction of a cent per transaction, which is cheap enough for everyday food purchases.
Do I need a crypto wallet to use this?
No. The app handles that for you. You won't see wallet addresses, only the networks you have joined and any requests waiting for your approval.
Who runs Common Source?
Common Source is run as an open project together with the partner networks listed above. Governance decisions are documented and recorded on-chain.
What does it cost?
The app is free. Each network sets its own terms for taking part. The small transaction fees on the ledger are paid by the network operator, not by you.
Is my data on a blockchain?
No. Your personal data stays on your phone. The only things written to the chain are cryptographic proofs, which confirm that something is true without revealing the underlying details. Your name, address and purchase history never go on it.
Take it with you

One identity. Every network.

Set-up takes about a minute. You don't need an email address or a password, just your phone.
