MVP Features

  • Admin can register domain names on behalf of other users (registrants).

  • Admin can delete domains.

  • Admin and registrant can change the target URL (Github Pages).

Examples

1. RegisterDomain

Register a new domain, set a target URL, and optionally give ownership to different account.

For the MVP, only the hardcoded admin (owner) can invoke RegisterDomain.

'RegisterDomain' ['AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y', 'somedomain.nos', 'https://deanpress.github.com/some-site-repo', 'AMrLse3suPd123HjSanwefCC5WQZPmjDYv']

  1. AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y is the address of the invoking user. Before executing the operation, CheckWitness() is run on this argument to make sure that the invoker is who they say they are. In this case, because we're registering a domain (Admin exclusive operation): it should always be AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y, the hardcoded admin domain.

  2. somedomain.nos is the domain we wish to register.

  3. https://deanpress.github.com/some-site-repo is the URL we wish to point it to.

  4. AMrLse3suPd123HjSanwefCC5WQZPmjDYv is the registrant. The address of the account we want to give the domain's priveledges to. Next to the hardcoded Admin account, this account will be able to invoke SetDomainTarget.

2. SetDomainTarget

Set the target domain.

For the MVP, both the hardcoded admin and the registrant can invoke SetDomainTarget.

'SetDomainTarget' ['AMrLse3suPd123HjSanwefCC5WQZPmjDYv', 'somedomain.nos', 'https://different-url.github.com/different-site']

  1. AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y is the address of the invoking user.

  2. somedomain.nos is the domain we wish to register. We have to be the registrar or the hardcoded admin account.

3. DeleteDomain

Delete a domain.

For the MVP, only the hardcoded admin can invoke DeleteDomain.

'DeleteDomain' ['AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y', 'somedomain.nos']
