demo-data-campaign-contract

This is the smart contract codes used to demonstrate data campaign within SWIPE network.

Contract attributes:

• minContributor: specify number of minimum contributor required before rewards can be disbursed to user.
• maxContributor: specify maximum number of contributors as per data buyer's budget.
• contributors: specify contributor address, publisher address, ipfs hash of the encrypted data, policy id, and capsule. Policy id and capsule is being used to perform reencryption.
• reward: specify number of SWIPE token to be distributed to users and publishers who contributed data.

Methods:

• contribute: records user consent to share encrypted data to data buyer.
• endCampaign: ends specific data campaign
• disburseReward: distributes rewards to contributors if no of contributor equals or more than minContributor attributes. Currently only logs reward distribution.

Considerations:

• Policy id and capsule which are used for data reencryption can only be accessible when campaign is ended and campaign meets number of minimum contributor.
• Reward is only distributed when campaign is ended and camapign meets number of minimum contributor.

Please note the codes have not been audited and should only be used for demonstration purposes.

Future roadmaps:

• Implements reward distribution.
• Allows storing of data buyer SWIPE token payment and refund address.
• Rewards tiering for publishers and users.
• Security audit.
