Supply Chains That Anyone Can Trust
Imagine scanning a code on your coffee bag and seeing the co‑op, harvest date, and roasting batch. Major retailers already pilot such traceability to shorten recalls and reward ethical growers. Would you try it and tell us what mattered most?
Decentralized Identity: Owning Your Digital Self
With verifiable credentials, you can prove you are over 18 without exposing your full birthdate. Selective disclosure preserves privacy while satisfying checks. Which everyday verification would you simplify first—age, residency, student status, or professional license?
Decentralized Identity: Owning Your Digital Self
Picture a digital wallet holding your workplace badge, travel pass, and library card. You choose what to present, and every presentation is cryptographically verifiable. Comment if you’d trust this more than re-uploading documents to countless websites.
Healthcare Records Without Friction
When labs, clinics, and specialists reference a shared integrity layer, records remain consistent across systems. The ledger doesn’t expose your data; it proves where it came from. How much time have you lost repeating medical histories?
Healthcare Records Without Friction
Grant research access for a month, then revoke it with confidence that every change is logged. Transparent consent builds trust between patients and researchers. Would you participate in studies more readily if control felt tangible and reversible?
Healthcare Records Without Friction
An ER physician checked a verified allergies credential during intake, avoiding a risky medication. Minutes mattered. The hospital didn’t browse your entire record—only what you permitted. Share your thoughts: which health facts should be instantly verifiable?
Education and Verifiable Credentials
01
Diplomas That Travel as Easily as You Do
Universities issue cryptographically signed diplomas that employers can verify in seconds. No notaries, no weeks of waiting. If you hire, would faster, trusted verification change how you screen candidates and reduce manual checks?
02
Lifelong Learning, Recognized
Short courses, bootcamps, and micro-credentials often get lost on resumes. On-chain proofs preserve context—issuer, date, competency level—so skills stay portable. Which upskilling achievement would you want permanently recognized and easy to share?
03
A Teacher’s Story
A school district tracked substitute-teacher clearances via verifiable credentials, cutting onboarding from weeks to days. Teachers spent more time in classrooms, less time in paperwork loops. Would this help your campus or company move faster with confidence?
Energy, Climate, and Transparent Impact
Households and businesses can match their consumption with renewable energy certificates recorded on an open ledger. No double counting, no vague reports. Would seeing hour-by-hour green matching change how you schedule energy use?
Energy, Climate, and Transparent Impact
Projects register methodologies, issuance, and retirement events on-chain, making every step auditable. Buyers trace impact beyond glossy brochures. Tell us: what proof would make carbon claims meaningful for you—satellite data, community audits, or third-party attestations?
Land titles, procurement milestones, and budget disbursements can be anchored on a ledger so changes become evident. Estonia’s approach to integrity layers inspired many. Which public dataset would you want verifiable first in your city?
Public Sector and Civic Trust
Residents vote on projects, and every allocation is traceable from proposal to payment. Fewer rumors, more collaboration. If your neighborhood could track spending in real time, would you participate more actively in local decisions?
Public Sector and Civic Trust
Provenance for Pixels and Paint
Artists can link physical pieces to digital certificates and record transfers openly. Buyers check authenticity, creators trace their legacy. If you collect art or design assets, would traceable ownership influence your purchasing confidence?
Licensing That Actually Pays
Music or photo licenses can encode usage terms and automate revenue splits to collaborators. Fewer disputes, clearer statements. Tell us which creative industry you think needs transparent royalties most—and why it’s overdue.
A Documentary Team’s Win
An indie crew logged footage metadata and licensing on a shared ledger. Months later, a broadcaster verified rights in minutes, avoiding legal limbo. If you publish content, would verifiable rights reduce friction with partners and platforms?
