• Create a contract that manages the administration of the scooter-renting scheme : people rent a bike in a list, give it back and are charged accordingly
  • Create a fault-less contract on Remix
  • [] Create a mapping, avoiding the constructor to loop and gas overflow
  • [] Allow usage of non-integer (division purposes)
  • [] The deposit can only be redeemed 2 days later (2 days are sufficient for another one to make a claim)
• Create a contract that allows insurance mechanism
• Implement a token-based reward system, which allows for the insurer to handle the deficiency issue

What can an insurance contract do ?

• Record keeping for the token
• Keep a balance of premia and claim fees for auditability
• Receives the subscription money

Workflow :

• Buy insurance.
  • The client buys insurance (pays a premium upfront)
  • Then, will pay small premium every time they rent a bike
• Rent bike.
  • The client rents a bike
  • The admin checks on public insurance record if the guy is insured.
    • The premium is paid according to past accident count if insured
  • The deposit will be the same for everyone.
• At end of ride, the renter :
  • Can file a claim if the scooter is not in good shape any more.
  • Communicates with insurer to have the guy gain extra points.
  • If there is an accident :
    • The bike sharing contract can modify the count of accident.
    • The insurance contract will automate payment of one bike

======================================================== Ideas ========================================================

• Customer can reduce their accident count by redeeming a token --> TO IMPLEMENT IN INSURANCE CONTRACT
• Ban client (last resort, after fake declaration) --> TO IMPLEMENT
• A Proof-of-Existence contract where you must prove the bike still looks good.
• Send to repair shop the broken ones if it falls below a certain threshold ?
• Add IPFS geolocation ?

======================================================== Things to clean ========================================================

• The Bike Struct (with enum, no need for currentlyInUse !)

===========

• Initialize a number of deployed.

• When it is used for the first time, push it into the array !

• IF THE BIKE IS BROKEN, DEACTIVATE IT

===========

Possible tests :

• How much does the insured pay ?
• 5 tokens = -1 accidentCount

===========

• Security issue : what if the guy rents another one ? OK --> added enums

===========

• THE PEOPLE WHO HAVE INSURANCE MUST HAVE A PUBLIC VIEWABLE RECORD, COMMON TO INSURANCE COMPANY AND BIKE COMPANY
• TOKENCOUNT MUST BE PUBLIC AS WELL
