What it shows

  • Course completion triggers cryptographic signing as a background job.
  • Generated certificates must expose a permanent public verification URL.
  • External credential updates (like LinkedIn) extend completion asynchronously.

The takeaway

Couple cryptographically signed certificate rendering with zero-auth public verification endpoints.
