European Digital Credentials for Learning vs POK

European Digital Credentials for Learning provides tools for organisations to create, issue, view, store, share, and verify credentials for degrees, diplomas, micro-credentials, participation certificates, and other learning records. The Online Credential Builder makes reusable templates; the EDC Issuer can issue from those templates or take existing JSON credentials for sealing and delivery. Credentials may be emailed or sent to Europass and other EDC-compliant wallets, and holders can share links when their wallet supports them. The viewer checks matters including format, seal, owner, revocation, accreditation, and validity. Credentials need an advanced or qualified electronic seal, and the viewer checks its integrity. The infrastructure says it does not store the personal information layer added for recipients. It issues JSON-LD credentials aligned with W3C Verifiable Credential v1.1 and uses the European Learning Model. The web tools require free NexU software, which runs only on Windows. Issuer, Viewer, and Wallet components are open-source software for integration into an organisation’s own infrastructure. The infrastructure is free; the listed platforms are web and Windows.

POK (Proof of Knowledge) helps organizations issue, manage, and verify digital credentials and microcredentials, including Open Badges 3.0 credentials on blockchain. Each credential has a unique link and QR code that opens a public page with the issuer, holder, date, skills, and current status. Its template editor supports logos, backgrounds, typefaces, signatures, custom attributes, dynamic API images, and paper formats. Organizations can issue credentials in bulk from Excel or CSV files; the free plan has no user cap or added bulk-issuance cost. Connections include Moodle, Canvas, Blackboard, D2L Brightspace, and Open edX through LTI 1.3, Sana through xAPI, and other systems through LTI, API keys, REST API, or webhooks. LMS rules can issue credentials after course completion, optionally with a minimum grade. POK supports several credential standards and offers white-label branding. Its Free Web2 plan is free; blockchain verification is $0.30, paid once, or $3,000 a year for up to 50,000 credentials.
