x/review — Review module
The x/review module records reviews between lease counterparties: tenants
review providers on delivery quality, and provider-side standing accumulates
into a reputation that is portable across the whole marketplace and
tamper-evident by construction — reviews are chain state tied to real
leases.
Because a review requires an underlying lease, reputation cannot be fabricated by sockpuppet accounts at scale; combined with VEID identity gating, review farming is structurally expensive.
What it does
Section titled “What it does”Every completed lease opens a review window for both sides. Tenants rate providers on delivery quality, providers rate tenants on conduct, and each review lands as chain state bound to the lease it came from — visible across the whole marketplace rather than locked inside one interface.
That binding is the module’s anti-manipulation property. Only actual counterparties of a real lease can review, so manufactured standing is structurally off the table, and accumulated reputation feeds offer presentation and tenant choice wherever the participant goes.
Why it exists
Section titled “Why it exists”Repeat-game trust is what makes marketplaces work, and centralized platforms hold that trust hostage — leave the platform, lose your reputation. On-chain reviews make track records a public good owned by the participant who earned them.
Primary objects
Section titled “Primary objects”| Concept | Definition |
|---|---|
| Lease-bound review | A review permitted only between actual counterparties of a real lease. |
| Portable reputation | Track record held as chain state, not as a platform’s private asset. |
Core flow
Section titled “Core flow”- Serve — A lease completes. Delivery happened between verifiable counterparties — the precondition for any review.
- Review — Both sides rate. Tenants review providers on delivery quality; providers review tenants on conduct.
- Record — Reviews become state. Tamper-evident, tied to the lease, and visible across the whole marketplace.
- Compound — Standing compounds. Accumulated reputation feeds offer presentation and tenant choice — portability included.

What is a lease-bound review?
Section titled “What is a lease-bound review?”A review permitted only between actual counterparties of a real lease — the constraint that anchors reputation to delivery.
Can reputation be faked?
Section titled “Can reputation be faked?”Reviews require an underlying lease, which ties feedback to marketplace activity. That does not eliminate coordinated abuse. VEID is optional and may be required for a specific offer; it is not a universal anti-fraud guarantee.
What does portable reputation mean?
Section titled “What does portable reputation mean?”Your track record lives in chain state rather than a platform’s database: switch interfaces or providers and your earned standing travels with you. See How the marketplace works.
