Gig Contract (gig_contract)

The gig_contract module defines the core business logic for Standard Gigs. It orchestrates the entire lifecycle from creation to completion, integrating with the escrow_module for payments and rating_module for reputation.

Flows

1. Gig Creation

• Actor: Poster (Client)
• Action: Calls create_gig.
• Process:
  • Initializes a Gig resource under the poster's account.
  • Deposits the budget into the escrow_module.
  • Sets state to Open.
  • Stores the IPFS hash of the off-chain requirements.

2. Application

• Actor: Applicant (Worker)
• Action: Calls apply_by_signing.
• Process:
  • Worker signs the contract hash to signal intent and agreement to terms.
  • Worker's address is added to the signed_applicants list.

3. Assignment

• Actor: Poster
• Action: Calls assign_applicant.
• Process:
  • Poster selects a worker from the signed_applicants list.
  • State moves to Assigned.
  • Work can officially begin.

4. Completion & Payout

• Actor: Worker (Applicant)
• Action: Calls submit_completion with evidence hash.
• Actor: Poster
• Action: Calls complete_gig.
• Process:
  • State moves to Completed.
  • Funds are released from escrow_module to the worker.

5. Disputes

At any point before completion, either party can initiate a dispute via the dispute_module. The gig_contract allows the dispute module to modify the gig state to Disputed and eventually resolve it.
