An Issuer is an on-chain entity that issues Certificates in the Certificate Registry smart contract.

The issuer can be one of the following:

  1. Privately held public/private keypair, i.e. a regular Ethereum account

    • When you want a single party to be responsible for the issuance

    • Works in automated environments, but otherwise discouraged

    • NOT RECOMMENDED due to the fact that if the keypair is leaked, the issuance process is, compromised.

  2. Multisig wallet

    • Recommended when you want multiple parties to be in charge of the issuance process

    • A bit more complex setup in automated environments

  3. Smart Contract

    • The issuer can be ANY smart contract with an Ethereum address

    • Can be used when a more complex permissioning setup is needed as compared to the previous options
