Hosts are identity-verified before a listing goes live and every guest review is anchored to a confirmed booking and completed stay, so fake listings and fake reviews cannot enter the platform. Guests trust that a review reflects a real experience from a real guest at a real property.
Bind identity to listings and stays to reviews so trust rests on evidence, not moderation.
01.
Verify before listing. KYC and Identity Verification confirms a host's identity and the DID and VC Ledger issues a credential, so an unverified party cannot publish a listing at all.
02.
Anchor reviews to reality. The Provenance Notary ties each review to a confirmed booking and a completed stay, so a review with no matching stay simply cannot be written.
03.
Prove the host owns the claim. A listing carries the host's verifiable credential, letting a guest confirm they are booking from an identity-checked operator, not a cloned profile.
04.
Stop review farming. Each completed stay mints a single review right, so the same booking cannot be used to post multiple reviews or inflate a rating.
05.
Preserve the record. Once anchored, a review and its stay linkage are immutable, so neither host nor platform can quietly edit or delete inconvenient feedback.
06.
Let trust travel. Because reputation is anchored to the host's DID, a verified track record can follow the host rather than being locked inside one platform.
Follow a host from identity verification through a completed stay to a review that is provably tied to it.

Cerulea decomposes rental trust into modular contracts. Each layer verifies hosts, publishes credentialed listings, records stays, and anchors reviews so trust rests on evidence rather than moderation.
Verified identity and stay-bound reviews are a horizontal capability. Here is how different actors put them to work.
Gate listings behind host verification and bind every review to a completed stay, eliminating fake listings and review farming without relying on reactive manual moderation.
Key Asset Types
Give independent properties a portable verified reputation that travels with their identity, so genuine track records are not trapped inside a single booking site.
Key Asset Types
Verify operators and tie participant reviews to booked, attended experiences, protecting travelers from fabricated ratings on activities and excursions.
Key Asset Types
Whether you are bridging a legacy marketplace backend or onboarding hosts directly through a self-sovereign wallet, Cerulea routes both into one verified trust record.
For rental platforms on legacy backends. Existing host onboarding and booking events are translated into credentials and anchored stays through the API gateway automatically.

Building host verification, credentialed listings, stay-bound review minting, and immutable review anchoring from scratch requires specialised identity engineers and long trust-and-safety cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects marketplace trust-and-safety engineering benchmarks. Building host identity verification, binding reviews to confirmed stays, and hardening the flow against fake accounts takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your verification and review rules into pre-audited WebAssembly binaries and provisions the trust ledger instantly.
