Overview
ProofSpace is a no-code platform for issuing and verifying reusable digital credentials1. Organizations use it to let people prove facts about themselves, such as their age, identity, or role in a community, without storing sensitive data centrally. The product pairs a business dashboard with a free mobile wallet app, built on the Cardano blockchain through Atala PRISM1.
Key Features
- No-code credential design. Businesses build issuance and verification flows through a web dashboard rather than writing backend code, with webhooks and deep links for connecting to existing systems1.
- SSI OAuth sign-in. The platform adds verifiable credentials to the OAuth 2.0 standard so people can register or log in by scanning a QR code with the ProofSpace mobile app, replacing passwords with cryptographic proofs2.
- Identity and age verification at scale. ProofSpace supports document checks across 11,000 ID types in 230-plus countries and 48 languages, plus social account verification for seven major platforms2.
- Privacy-preserving data sharing. Selective disclosure, zero-knowledge predicates, peer-to-peer communication, and auto-delete rules give organizations fine-grained control over what user data they collect and how long they hold it1.
- ID2020 certification. Ledger Insights reports that the mobile app was only the third product globally to earn certification from the ID2020 Alliance, a digital-identity standards body whose backers include Microsoft, Accenture, and the Rockefeller Foundation3.
What to Expect
Visitors arriving at ProofSpace encounter a business-to-business product aimed at organizations that need to verify customers, members, or staff without building identity infrastructure themselves. The platform is built by a London-based team that rebranded from ZAKA to ProofSpace in March 20224. The product pitches to three main audiences. Organizations running services, such as governments, universities, marketplaces, and community platforms, can sign up for a dashboard that handles KYC, AML, age checks, and passwordless sign-in via SSI OAuth. Developers integrating ProofSpace into existing apps get webhooks, deep links, and an integration-examples repository on GitHub. End users install the free ProofSpace mobile app on iOS or Android, collect credentials from any organization that issues them, and reuse those credentials elsewhere without verifying again1.
Pricing starts with a free tier for up to 15 monthly active users and moves through fixed-fee Build and Grow plans, with per-interaction charges applying above a thousand credentials per month5. Technical reference material lives in a public Confluence knowledge base, and the founding team has been featured in Forbes and the Wall Street Journal. ProofSpace has also submitted eight proposer-led proposals to Project Catalyst between Funds 8 and 10, spanning credential-based KYC, mental-health credentials, ADA-payment integrations in identity workflows, and translations of its platform into Japanese, Spanish, and Swahili.
