The trust layer for vacation rentals

Vera – Boekingsbescherming

Vera is HemmaBo's regelgebaseerde boekingsbescherming: twee gasten kunnen niet dezelfde datums boeken — de database weigert de tweede. Prijs en datums worden gecontroleerd en vergrendeld tijdens de betaling.

Vera — rule-based booking protection

Vera is how HemmaBo implements booking protection on top of the open Vacation Rental Protocol (VRP). It is deterministic (if/else), not a guessing AI: availability checks, price-and-date validation, and a temporary date lock during payment. Two direct bookings cannot hold the same dates — a database-level no-overlap constraint refuses the second. Each booking can be recorded in a tamper-evident log. The host's own domain stays the source of truth; VRP signs the stay offer with Ed25519, verifiable connector-free for AI agents.
