A Subscription Management Contract developed using the Marlowe programming language can be designed to handle subscription-based courses or services, managing payment verification, access control, and renewal processes. Here's an elaboration on each aspect:
Subscription Management: The contract would include the necessary logic to manage subscriptions for courses or services. It would define the terms and conditions, including the subscription duration, pricing, and any other relevant information.
Payment Verification: The contract would incorporate a payment verification mechanism to ensure that subscribers have made the required payments. This could involve integrating with a payment gateway or using a cryptocurrency payment system. The contract would verify that the payment has been successfully made before granting access to the subscribed content or service.
Access Control: The contract would include access control mechanisms to restrict access to the subscribed content or services to only authorized subscribers. It would maintain a list of valid subscribers and their access rights. The contract could utilize unique subscriber addresses or credentials for access control purposes.
Renewal Process: The contract would manage the renewal process for subscriptions. It would define the renewal conditions, such as automatic renewal or requiring manual confirmation. If the subscription is set to automatically renew, the contract would handle the payment processing and extend the subscription period accordingly. If manual confirmation is required, the contract would notify the subscriber in advance and provide instructions for renewal.
Subscription Cancellation: The contract would also include provisions for subscription cancellation. It would outline the conditions under which a subscriber can cancel their subscription and any applicable refund policies. The contract would handle the necessary verification and process any refunds, if applicable.
Subscription Upgrades/Downgrades: If the subscription service offers different tiers or levels, the contract can handle subscription upgrades or downgrades. It would define the conditions for upgrading or downgrading a subscription and adjust the pricing and access rights accordingly.
Notifications and Reminders: The contract can include features to send notifications and reminders to subscribers. These notifications can include subscription renewal reminders, upcoming course or service updates, or any other relevant information.
Smart Contract Escrow: To ensure fairness and transparency, the contract can utilize smart contract escrow mechanisms. This would hold subscriber payments until certain conditions are met, such as successful access provision or completion of a course or service.
