  "account": "The vehicle rental smart contract uses several key Solidity concepts to manage vehicle records, user information, and booking details. Vehicles are stored in a mapping where the vehicle registration number serves as the unique key. Each vehicle struct contains fields such as registration number, name, rental price, availability status, seating capacity, and ownership address. Users are similarly stored in a mapping keyed by their Ethereum wallet address. The user struct contains name, age, and phone number fields. Booking information is managed using another mapping with a booking ID as the unique key. The booking struct includes fields such as booking ID, rental start and end times, total amount, vehicle identifier, rented customer address, and current status. Enumerations are used to define the possible booking statuses like pending, booked, completed, or cancelled. Access control is enforced through modifiers that check whether an operation is authorized based on the sender's role. For example, only the vehicle owner can modify vehicle details, while only registered users can create bookings. Modifiers simplify the enforcement of these permissions without duplicating access checks in each function. Overall, the contract organizes data and access control using structs, mappings, enums, and modifiers to create a functional prototype for a vehicle rental system on the Ethereum blockchain using Solidity.",
  "summary": "Building a Vehicle Rental Smart Contract Using Solidity A practical introduction to structs, mappings, modifiers, and booking management in Ethereum smart contracts. Introduction Imagine renting a vehicle without depending entirely on a centralized rental management system. Vehicle information, customer registration, and booking records could be managed through a smart contract, with the rules…",
