Mission Portal Disclosure

What a backing action is

A backing action is a private expression of support for a Techs in the City mission — a location, event, or conference you want Dungo Digital to cover. It is not a purchase, a public statement, or a binding financial commitment.

How the privacy works

Your backing action is processed by a zero-knowledge circuit on the Midnight network. The circuit does two things:

• Produces a cryptographic commitment that proves a valid action was submitted, without recording what you chose or who you are.
• Generates a nullifier that prevents you from submitting a second action for the same mission.

What cannot be undone

Once you submit a backing action, the cryptographic commitment on the Midnight network is permanent. It cannot be withdrawn, reversed, or deleted — by you, by Dungo Digital, or by anyone else. This is not a policy; it is a technical property of the blockchain network.

If you delete your Dungo Digital account, we will delete the database receipt (timestamp, mission ID, proof hash). The on-chain commitment will remain.

Backing actions are final. There is no undo.

What gets published

When a mission reaches its backing threshold, an unlock proof is generated and published publicly on dungodigital.io. This proof confirms that the threshold was met and shows the mission outcome. It does not identify you, reveal your choice, or link back to your account in any way.

What you are consenting to

By proceeding, you consent to:

• Processing your input through a zero-knowledge circuit on the Midnight network
• A permanent on-chain cryptographic commitment that cannot be deleted
• Publication of an unlock proof if the mission threshold is reached — this proof does not identify you

This consent cannot be withdrawn after submission.

Questions

Contact us before submitting if you have questions about how this works. Once a backing action is submitted, we cannot undo it on your behalf.
