Topic Summary (TL;DR)
Certification on a Beckn-enabled network works by listing the network participants on the registrars of the certification authority. Any network participant listed on an open registry is implicitly assumed to be certified. The certification requirements may vary based on the nature of the network.
Certification is a process for any participant on a Beckn-enabled network to show proof of compliance towards that network. This proof of compliance is in the form of a digital certificate issued by one or more certification agencies. After the certificate is issued, it is uploaded to a network registrar which validates the certificate against the network rules and policies specified at the network, city, and/or global levels.
After the certificate is validated, the registrar makes an entry for that participant in their open registry. Any network participant listed on an open registry is implicitly assumed to be certified.
This is what a digital certificate issued by a certification agency looks like: Certifications could be for various purposes, such as compliance with some requirements or regulations, migration to a new version of the protocol, renewal of certification, and others. The certification agencies can create multiple certificates in order to manage compliance across networks.
