Primus Labs and HashCloak seek Canton Development Fund backing for private-data proofs
CantonNews (October 2, 2026): Primus Labs and HashCloak have requested 1,303,500 CC from the Canton Development Fund for a 14-week project to verify facts drawn from private web data without exposing the underlying information. A Canton application would check a cryptographic proof instead of receiving raw data—supporting financial or identity checks where confidentiality must hold. HashCloak would build verification tooling; Primus would connect it to its existing proof-generation stack, with an example showing developers how to consume results on Canton. The teams previously collaborated on private-data verification for Aztec; this submission is a separate Canton funding request with its own milestones and open-source deliverables. The proposal remains open and is not yet approved; nothing is live on MainNet.
