In the Web2 era, to "book" was to make a reservation through a powerful centralized aggregator. Platforms like Expedia, Booking.com, or Airbnb acted as trusted intermediaries, managing inventory in a private database and connecting consumers with service providers. The booking itself was a static, non-transferable entry owned by the platform. This model created convenience but also introduced high commission fees for providers and often rigid cancellation policies for consumers, as the intermediary controlled the rules, the customer data, and the financial transaction. In the Web3 and Fourth Industrial Revolution (4IR) paradigm, to "book" is to acquire a unique, verifiable, and transferable digital asset, typically an NFT, that represents your reservation. Booking a hotel room, a flight, or a concert ticket means minting an asset that grants you specific rights at a specific time, with the terms encoded in a smart contract. This transforms the booking from a simple database entry into a liquid asset that can be sold or traded on a secondary market if plans change. This disintermediates the aggregators, reduces costs, and gives both the service provider and the consumer greater flexibility and control over the terms of the agreement.
