DIN Prototype

Prototype of reward disbursement for the DIN system. Uses a commit-and-reveal scheme for scoring by validators.

Overview

There are three types of users:

• Owners: create projects and provide the reward
• Contributors: provide the data to train the model
• Validators: score contributors' data

The timeline of a project is as follows:

• The owner creates a project with createProject, and adds contributors and validators with addContributors and addValidators, respectively
• The owner starts the project with startProject. From that moment, validators can assign a score to each contributor until a specified deadline
• For each contributor, the validator first commits the salted hash of the score using commitValidations. Once the commitment deadline has passed, all validators reveal the salt and the score with revealValidations. Only reveals that correspond to the initial commitment are counted
• Contributors and validators receive rewards by calling collectContributorReward and collectValidatorReward. These rewards are taken from separate pools and use different distribution mechanisms.
  • Contributors receive a share of the total reward depending on the mean score assigned by the validators
  • Validators receive a share based on the number of valid reveals

The contract also features view methods for easier UI integration.
