AI travel agents should be able to discover hotels that expose their metadata, rates, and availability via MCP servers, then surface those properties in natural language search results with the AI's ability to compare, summarize, and generate contextual itineraries. Find inspiration in AI travel agents like Perplexity's travel agent etc.

Design (not build) how agents can process bookings via secure blockchain interactions. Focus on seamless digital identity and payment verification through blockchain-based systems. Elaborate on why blockchain enhances AI agent booking capabilities (identity verification, payment processing, transaction transparency and traceability).

Use the Camino Messenger to create non-refundable hotel bookings so guests can resell, transfer, or sell them back to the hotel on a transparent secondary market, managed by smart contracts. Build a simple web interface where users can "transfer," and "sell back" hotel stays, showing state changes in real time.

See TripResale and other suppliers for the hotel benefits for this challenge (TripResale), Takyon | Not for Tourist - Direct Bookings. Best Rates. No Commissions. and Fairlyne resale platform - Fairlyne, for example.

The system should provide fraud-resistant handling of bookings, cancellations, and importantly, modifications (as additional blockchain transactions). The dApp must ensure traceable, tamper-proof reporting, minimizing manual reconciliation efforts. Facilitate transparent reconciliation with guaranteed audit trails accessible to all stakeholders.

Since bookings on chain are immutable, handle modifications as additional transactions that update the booking state. Use "stacked NFTs" or linked tokens to represent modifications and the current state of the booking. Propose a Camino Messenger Format for Modification.

Upon receiving a confirmed booking with a known end-consumer's digital wallet address, the system should intelligently propose personalized upsell offers that match the guest's preferences and profile, avoiding irrelevant or annoying push offers.

Use the blockchain wallet address associated with the guest to securely create/link to their historical CRM or loyalty profile data (preferences, past stays, spend patterns). Use AI to analyse (mocked) CRM data, past booking context, and guest behaviour to generate upsell offers (room upgrades, dining, spa, experiences) with high relevance and likelihood of acceptance.

It is branded with the hotel brand where the guest booked their stay but is interoperable and portable across multiple hotel brands connected to the same channel manager ecosystem. It should be a guest-centric rewards ecosystem that significantly improves engagement and value perception for hotel guests.

The system should modernize and solve common loyalty program pain points by offering instant usability, protecting point value, preventing expiry or devaluation, and using AI to personalize rewards and offers based on guest preferences and history. Guests can use, transfer, or trade tokens across hotel brands on the same channel manager, with all transactions recorded transparently and auditable on-chain. Points do not expire or degrade in value, immediate redemption options for a wide variety of services and incentives for trading or gifting points.

Following the Architecture and Reference Framework (ARF) specifications available at GitHub - eu-digital-identity-wallet/eudi-doc-architecture-and-reference-framework: The European Digital Identity Wallet . Choose one specific travel booking scenario from: agents booking on behalf of clients, parents booking for minors, corporate travel managers booking for employees, or AI agents operating with user delegation.

For your chosen use case, create a credential verification system that can validate identity claims, delegation permissions, and booking authority. Implement secure credential presentation flows that preserve privacy while ensuring compliance with travel industry regulations. The solution should demonstrate seamless integration with existing travel booking workflows while providing tamper-proof audit trails of authorization decisions for your specific scenario.

Create logic to analyse booking requests and intelligently match them with suitable travel suppliers based on destination, service type, price range, and quality metrics. Implement a supplier discovery mechanism that maintains an updated catalogue of available services and their capabilities.

Enable instant payments using on-chain currency USDC or Monerium's EURe currency through blockchain infrastructure. The system should optimize for both speed and cost-effectiveness while maintaining transparency in supplier selection and pricing.
