[aahna-ashina]

To avoid administration costs (launching the SourceCred UI locally takes 1-2 hours), make it possible for new Nation3 contributors to self-activate their SourceCred identity (via the NationCred contracts).

• Determine if this code should be implemented in this repository (sourcecred-instance) or in the datasets repository (nationcred-datasets).

GitHub

• Fetch GitHub usernames from https://github.com/nation3/nationcred-datasets/blob/main/data-sources/github/output/github-usernames.csv
• If the GitHub username does not already exist in the SourceCred ledger, add it
• If the GitHub username already exists in the SourceCred ledger, add the citizen's Ethereum address as the identity's payoutAddress
• If the GitHub username was added as a new identity, add the citizen's Ethereum address as the identity's payoutAddress

Discord

• Fetch Discord usernames from https://github.com/nation3/nationcred-datasets/blob/main/data-sources/discord/output/discord-usernames.csv
• If the Discord username does not already exist in the SourceCred ledger, add it
• If the Discord username already exists in the SourceCred ledger, add the citizen's Ethereum address as the identity's payoutAddress
• If the Discord username was added as a new identity, add the citizen's Ethereum address as the identity's payoutAddress
