Problem Statement

Anyone can create a stash campaign with description, a rectangular area, reward per submission and maximal number of submissions. Rewards can be paid in any ERC-20 token.Each user can create a submission with a photo, description and coordinates. All info is stored on our server, hash goes onchain.Reward is allocated immediately, but it is locked for ~3 months. Additionally, user must cast all required votes before getting it.Verifiers are chosen randomly among other users. If a vote is not unanimous, new set of verifiers is sampled. After the vote is finalized, there is a 1 month period for disputing, which requires a deposit and could be done by anyone.Incorrect votes punished by half of their locked reward (or full disputror deposit / submitter reward), these are shared equally among all correct voters.

Solution

Onchain EVM logic (deployed on several blockchains) that manages rewards, voting, campaign and submission management. It creates socio-economic incentives to maximize the soft guarantees of the correction of onchain submissions.Backend logic listens to blockchain events among different chains and updates the state for frontend, joining information from all blockchains into one source.Frontend signs and sends transactions and updates UI based on the updates from the blockchain, communicated via events. We have integrated open maps to display locations.
