In their own words
POK
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.
