Knowledge belongs
to everyone.
Free, open-source learning for every platform. Peer-to-peer, offline-first, with Verifiable Credentials anchored to Cardano.
macOS · Windows · Linux · iOS · Android
Education without infrastructure.
No cloud servers, no subscriptions, no data collection. Just a native app that connects learners directly.
Learn Without Limits
Structured courses, short-form video tutorials, and Field Commentary from credentialed practitioners — all free and open-source. A native app that works offline, syncs peer-to-peer, and runs on every platform.
- Structured courses with real assessments
- Works offline — no internet required
- Runs on macOS, Windows, Linux, iOS, Android
Earn Verifiable Credentials
W3C-style Verifiable Credentials, Ed25519-signed under your own DID and anchored to Cardano (preprod testnet) by hash. Independently verifiable without the platform — even offline.
- Six credential types: formal, assessment, attestation, role, derived, self-asserted
- Selective disclosure — share only the level, hold back the rest
- Self-contained offline bundles for employers and registrars
Own Your Data
Your keys, your identity, your content. Everything stored locally with AES-256-GCM encryption. Peer-to-peer sync — no cloud, no corporate servers.
- Self-sovereign identity with local key vault
- Content-addressed storage via iroh
- P2P networking — no central server
Community Governed
DAOs mirror the knowledge taxonomy. Elections, nominations, and voting are driven by demonstrated expertise — not money.
- Meritocratic governance model
- Reputation-based voting power
- Transparent, on-chain decisions
How it works.
From download to decentralized credentials in four steps.
