Contributor Transactions

Project contributors can commit to and complete tasks. Contributors must meet the project's prerequisite requirements (typically holding credentials from specified courses).

Available Transactions

Contributor Role

Contributors are users who work on project tasks. To become a contributor:

1. Meet Prerequisites: Hold the required course credentials
2. Commit to Task: Use task-commit to enroll and commit in one transaction
3. Submit Evidence: Provide task_info as proof of work
4. Await Decision: Managers assess the submission

Key Concepts

Prerequisites via contributor_state_id

Projects define prerequisites using contributor_state_id - a policy ID representing the credential a contributor must hold. This is a compact way to verify course completion without listing individual SLT hashes.

First Enrollment Mints Token

When a contributor commits to their first task in a project, the transaction mints a contributor-state token. Subsequent commits update this token rather than minting new ones.

Global State Credential

Upon enrollment, the project credential is added to the contributor's global state credentials map. This enables cross-project credential verification.
