Certify Internet data with Tisura

Dossier Certifier ensures the authenticity and integrity of documents collected online by certifying both their origin and content. It replaces AI fraud detection or manual checks with deterministic cryptographic proof.

Tisura allows developers to cryptographically prove authorship of their contributions on GitHub — commits, issues, or pull requests — ensuring verified ownership for hiring, grants, or funding applications.

Tisura offers privacy-preserving identity verification: users prove their identity using cryptographic proofs without sharing personal details. Ideal for onboarding, age verification, or KYC without compromising privacy.

Tisura enables rental platforms to verify that submitted documents (like pay slips or tax notices) truly originate from the trusted data sources and haven’t been altered. This prevents fraud and accelerates trust in the application process.

Lenders use Tisura to ensure that key financial documents — bank statements, tax records, ID proofs — are authentic and sourced in real time. This reduces risk and boosts confidence in digital loan applications.

The Trustless Airdrop Launchpad lets anyone run an airdrop where eligibility is provable and verifiable by all — no backend trust required. Claimers generate zero-knowledge proofs from cryptographically certified GitHub data.
