AxiomIncentives

The AxiomIncentives abstract base contract allows applications to offer incentives based on provable on-chain activity associated with receipts on Ethereum. This system requires that each rewarded action, which we call a claim, be uniquely associated with an event log. We identify each claim with:

• uint256 claimId -- a monotone increasing identifier for all Ethereum receipts
• uint256 incentiveId -- a unique identifier of the rewarded user
• uint256 claimValue -- a numerical measure of the value of the claim, e.g. the fees paid in a transaction.

To prevent double claiming, we enforce that claims must be made in increasing order of claimId. Users can prove claims in a batch, and Axiom provides the following ZK-proven results to AxiomIncentives via callback:

• uint256 startClaimId -- the smallest claimId in the claimed batch
• uint256 endClaimId -- the largest claimId in the claimed batch
• uint256 incentiveId -- the incentiveId for all claims in this batch
• uint256 totalValue -- the sum of claimValue over all claims in the batch.
