Check project vouching data and update project's verification points

[divine-comedian]

Create a service that checks the latest DeVouch attestation data and updates the project’s verification points depending on which attester orgs issued each vouch.

• Giveth Verifiers = 1 point
• TRAINED Giveth Verifiers = 3 points
• Core Reviewer = 30 points

Verification levels

Projects must have a certain amount of points

Verification level 1

For the purposes of staging/testing the vouching threshold will be 2. So if a project has receive 2 eligible vouches its project status should be changed to Verified level 1.

e.g If a project receives 2 vouches from a Giveth Verifier it is automatically verified within 24 hours

Ideally we can handle checking this data real-time as the DeVouch indexer processes on-chain events. If we are not able to handle real-time events then a delay of up to 12 hours is acceptable.

Notes

• on every event that happens we can make a hook in the impact-graph that can be called - we should protect this by some password so only 1 BE can call it to push information to impact-graph
• create list of updated statuses, create API in DeVouch BE, fetch projects that are updated by impact-graph
• Otherwise we check data at least every 12 hours and update projects’ status

Requirements

• The number of points required to become automatically verified can be easily changed by a developer
• The number of points each type of Verifier is worth can be easily changed by a developer
• changing the “points threshold” does not retroactively affect projects’ verified status
  • we can remove the status, keep track of time of project has been updated, fetched project has been updated until 1 hour ago, only fetch projects from after that. If we change the threshold
• If a Giveth Verifier changes their vouch or revokes it, and the project then becomes under the threshold then we unverify the project.
• when the amount of vouches a project receives attains the set threshold the project's status changes to "Verified" within a maximum delay of 12 hours
• If a project's vouches are revoked and it falls under the threshold then the project loses it verified status within a maximum delay of 12 hours.
