Certbant

Certbant is a standards-based framework for issuing, managing, and verifying digital certificates and attestations across organizations and individuals. It combines cryptographic signatures with a distributed registry to create tamper-evident credentials that can be validated by participants in a network. Built to support education, employment, and regulatory compliance, certbant emphasizes portability and privacy-preserving verification of credentials rather than centralized control of user data.

Origins: The concept emerged from the CertBant Alliance, formed in 2021 to address weaknesses in traditional PKI and the rising demand for verifiable credentials. Early pilots focused on universities delivering digital diplomas and healthcare facilities issuing professional attestations. The project grew to include industry standards bodies and several pilot jurisdictions.

Key components include trusted authorities (root and intermediate issuers), verifiable credentials (signed data packages), revocation registries, and verifiers. Certbant supports selective disclosure, enabling holders to share only necessary credential facets, and can operate over public or permissioned ledgers, with interoperability layers to connect with existing PKI and DID ecosystems.

Governance and adoption: A multi-stakeholder governance model coordinates standards development, accreditation of issuers, and maintenance of revocation data. Adoption has been incubated through academic and governmental pilots, with wider uptake contingent on interoperability with legacy systems, cost considerations, and clear privacy safeguards.

Pros and challenges: Advocates cite improved credential portability, reduced fraud, and streamlined verification. Critics point to scalability, potential privacy risks from broad revocation data, and the need for robust governance to prevent mission creep or credential monopolies.
