# Example 1 Course Certification (Proof of Action)
After completing an online course the course creator issues a Certificate to the student and endorses it.
The student can accept the certificate by signing it. The student can also delete it. The student can also choose who can see the details of the certificate, which can include credentals, course topics, as well as any txhashes or other data references.
A optional value in some currency can be placed on the certificate – this can be based on the duration of the course, cost of internet and so on.
Anyone can redeem the Cert. Say a business offered the student a voucher for their store with a stated value in some currency. If the Student executes an AcceptRedemption the interaction will be appended to the certificate which can be seen by future redeemers and marketplaces.
