Mission Portal Disclosure
This disclosure explains what happens when you submit a backing action in the Mission Portal. Read it before proceeding. It supplements the main Terms of Use and Privacy Policy.
Version mission-portal:1 · Effective May 17, 2026
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 It cannot be withdrawn, reversed, or deleted — by you, by Dungo Digital, or by anyone else.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This consent cannot be withdrawn after submission.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.
