Private reputation on Solana
Prove your history.Keep it private.
MASK lets users prove reputation, activity and past behavior without exposing balances, addresses, counterparties or the full wallet behind the proof.
SELECT → PROVE → VERIFY → SHARETRUST WITHOUT OVERSHARING
Why MASK
Reputation should not require exposure.
Onchain identity often asks users to reveal far more than the application actually needs. MASK separates the fact being proven from the private data used to prove it.
Without MASK
A full wallet becomes the reputation profile.
Balances, addresses, transaction patterns and counterparties can all become visible even when an app only needs one simple answer.
With MASK
Only the verified fact is shared.
Users choose the claim they want to prove. MASK generates a proof while the underlying wallet data stays private.
The mechanism
Select. Prove. Verify. Share.
MASK turns private history into reusable, selective proofs.
02
Prove
The proof engine evaluates the relevant private history without publishing the raw wallet data.
03
Verify
The receiving app checks whether the proof is valid and whether the requested condition was satisfied.
04
Share
Only the result leaves the private layer — enough to establish trust without revealing everything else.
Only the fact is visible.

FAQ
Trust without oversharing.
What is MASK?
MASK is a private onchain reputation layer that lets users prove specific facts about their history without revealing their balances, addresses or complete wallet activity.
What can users prove?
Examples include loan repayment, completed contracts, meeting deadlines, passing verification, and reaching a required transaction or activity threshold.
Does MASK create one universal credit score?
No. The concept is based on selective, claim-based reputation: prove the fact needed for a specific context rather than reducing the user to one opaque score.
What does the receiving app see?
The app receives the proof result needed for the requested claim. The sensitive underlying wallet data is not part of the shared credential.
