Blockcerts vs Certipha

Blockcerts is an open standard and open-source ecosystem for creating, issuing, receiving, and checking blockchain-based credentials and official records. Its intended settings include civic records, education, professional licensing, and workforce development. Recipients can use the Blockcerts app to receive, import, keep, and share credentials; a private passphrase supports ownership and recovery. A universal verifier checks records independently and can be incorporated into other software. Developer resources include Python tools for creating and issuing credentials, a JavaScript verification library for Node.js or browsers, and a standalone web verifier. The issuer library supports Bitcoin and Ethereum, while the standard is designed to work across blockchains. Verification checks issuer signatures and certificate data, including expiry and revocation. Issued certificates cannot be edited, though an issuer can revoke an incorrect one or issue a replacement batch. Blockchain data is a one-way hash of certificate information. Blockcerts is free; Bitcoin batch issuance may incur a variable network transaction fee.

Certipha is a certificate issuance and verification platform for publishers, trainers, employers, and other organizations. It handles publication, conference, training, employment, membership, award, internship, and service certificates. Issuers can upload recipient lists in CSV or XLSX format, generate PDFs, and download them together in a ZIP. Ten designer templates, issuer branding, custom prefixes, signatures, and branded QR codes support presentation choices. Anyone can check a certificate by ID or QR code on a public page without an account. Issuers can revoke certificates with a reason, with status updates shown on that page. DOI import retrieves article metadata from CrossRef or Zenodo, while optional email delivery uses the issuer’s Resend setup. A REST API supports tenant-scoped issuance keys, and an embeddable badge displays current status without tracking cookies or external dependencies. Workspaces include admin, editor, and viewer roles.
