Check-in

Detailed Check-in Process Using Smart Contracts

The check-in process in DeGym leverages a robust smart contract system designed to handle interactions securely and efficiently:

1. Consumer Check-in Initiation:

   • Action: The consumer arrives at the gym and opens the DeGym DApp.

   • Process: The consumer selects the check-in option which triggers the app to interact with the smart contract on the blockchain.

2. Smart Contract Activation:

   • Validation: The smart contract first verifies the authenticity and validity of the consumer's NFT voucher for the current day.

   • Simultaneous Validation: The gym’s commitment is verified by checking the staked amount in the blockchain to ensure the gym's eligibility to receive payments.

3. Conditions Verification:

   • Membership Tier: Checks if the consumer's voucher tier corresponds to the gym's accepted tiers.

   • Gym Compatibility: Ensures that the gym is part of the network and ready to accept check-ins from the consumer’s voucher tier.

4. Transaction and Check-in Execution:

   • Payment Transaction: If all conditions are met, the smart contract facilitates the transfer of funds from the consumer's wallet to the gym's account.

   • Usage Log: The smart contract records the use of the voucher for that day, decrementing the available days or sessions from the NFT.

5. Confirmation and Receipt:

   • To Consumer: The consumer receives a digital receipt and confirmation on their app that the check-in was successful and payment has been made.

   • To Gym: The gym receives confirmation that the funds have been transferred to their account and the consumer’s entry is authorized.

6. Error Handling:

   • Insufficient Funds: If the consumer’s wallet has insufficient funds, the transaction is aborted, and an error is reported.

   • Invalid Membership: If the NFT is not valid for the day or tier, the check-in is denied.

7. Post-Check-in Actions:

   • Feedback Request: The consumer is prompted to rate their experience, providing valuable feedback to the gym.

   • Usage Analytics: The gym receives data about the frequency of visits, which helps in planning and resource allocation.
