  • source_contract - Address of the old contract to migrate from
  • expected_protocol_version - Expected version of the source contract

Returns

  • MigrationResult - Details about the migration including validation counts

Panics

  • If caller is not the admin

Update a role-based score for a verifier

Role-based reputation allows for context-specific scoring. Hierarchy: Domain → Aspect → Role

For example:

  • Domain: Hospitality
  • Aspect: Dining
  • Role: Guest (score: 850)
  • Role: Host (score: 400)

This allows someone to have high reputation as a dinner guest but low reputation as a dinner host.

Arguments

  • verifier - The verifier whose role score is being updated
  • role_key - Compound key "aspect:role" (e.g., "dining:guest", "ride_sharing:driver")
  • delta - The change to apply (positive or negative, e.g., +30, -50)
  • scorer - The account submitting this score update (must authenticate)

Behavior

  • If role doesn't exist, initializes to 500 (neutral) then applies delta
  • Caps final score at [0, 1000]
  • Requires auth from scorer

    env: soroban_sdk::Env,
