Trust Infrastructure for Real Estate
The missing layer between sensors and tokens.
You can instrument a property with sensors (DePIN Devices). You can tokenize ownership (Tokenization). But who verifies the property itself? Who confirms ownership, history, condition, and rights?
This is the trust infrastructure gap — and it's wide open.
The Problem
Real estate runs on fragmented, paper-based truth:
| Data Type | Current State | Friction Cost |
|---|---|---|
| Ownership | County-by-county records, paper deeds | Title search: $500-2,000 + weeks |
| Listings | 800+ independent MLSs, no standard | Agents pay $50-500/mo per MLS |
| Transaction History | Siloed, incomplete, delayed | Price discovery: opaque |
| Property Condition | Periodic inspection, self-reported | Insurance disputes, fraud |
| Agent/Owner Reputation | Zillow reviews, unverifiable | Trust deficit |
Total friction cost: 5-10% of every transaction goes to intermediaries who verify information that could be on-chain.
Why Hasn't Blockchain Fixed This?
| Barrier | Reality |
|---|---|
| Technical? | No — blockchain can record property rights. Georgia, Rwanda, Sweden have pilots. |
| Regulatory? | Partly — US state-by-state land recording laws vary. But not insurmountable. |
| Political? | Mostly — Incumbents (NAR, title companies, MLSs) benefit from fragmentation. |
| Network effects? | Yes — First mover needs critical mass. Chicken-and-egg problem. |
The insight: Zillow and Redfin aren't solving MLS fragmentation — they're exploiting it as a competitive weapon. The FTC filed antitrust claims against them in 2025 for using listing bans to eliminate competition, not to create unification.
Global Status: What's Deployed
| Country | Implementation | Status | Lesson |
|---|---|---|---|
| Rwanda | National cadastre fully digitized (2023) | ✅ Operational | Greenfield easier than retrofit |
| Georgia | Blockchain land registry | ✅ Operational | Early mover advantage |
| Sweden | ChromaWay pilot since 2016 | 🟡 Pilot | Institutional inertia slows progress |
| UAE | Dubai Land Department blockchain | 🟡 Growing | Government mandate accelerates |
| UK | HM Land Registry "Digital Street" | 🟡 Pilot | Regulatory clarity exists |
| US (Vermont) | Propy pilot in South Burlington | 🟡 Pilot | State-by-state is hard |
| US (Wyoming) | Teton County with Medici Land Governance | 🟡 Pilot | Limited to post-1996 records |
Pattern: Full deployment happens where (a) government mandates it, or (b) existing systems are so broken that blockchain is clearly better. Neither condition exists in mainstream US markets — yet.
The Opportunity Layers
Layer 1: Property Registry (Ownership Truth)
What it replaces: County recorder offices, title companies, paper deeds.
| Component | Current | Blockchain Version |
|---|---|---|
| Deed recording | County clerk, paper | Immutable on-chain record |
| Title search | Manual, 1-2 weeks | Instant query |
| Title insurance | $1,000-3,000 per transaction | Reduced/eliminated (verifiable chain) |
| Lien recording | Fragmented across systems | Single source of truth |
Who's building:
- Propy — End-to-end blockchain closing, Vermont pilot
- Medici Land Governance — Government partnerships, Wyoming deployment
- Ubitquity — Enterprise title recording
The moat: First registry to achieve network effects becomes the standard. Winner-take-most dynamics.
Layer 2: Listing Registry (Market Truth)
What it replaces: 800+ independent MLSs with incompatible data.
| Component | Current | Blockchain Version |
|---|---|---|
| Listing data | Fragmented across MLSs | Unified, permissioned access |
| Price history | Delayed, incomplete | Real-time, complete |
| Days on market | Gaming via relisting | Immutable history |
| Agent performance | Unverifiable claims | Verified transaction record |
Who's building: Effectively nobody. Zillow and Redfin have data but won't unify — fragmentation is their moat.
The gap: A decentralized MLS alternative that agents and buyers can trust. First mover with critical mass wins.
Layer 3: Condition Registry (Physical Truth)
What it replaces: Periodic inspections, self-reported condition, insurance disputes.
| Component | Current | DePIN + Blockchain Version |
|---|---|---|
| Property condition | Point-in-time inspection | Continuous sensor attestation |
| Maintenance history | Owner-claimed | Verified on-chain records |
| Insurance claims | Dispute-prone | Parametric triggers from sensors |
| Due diligence | Weeks of investigation | Query verified data layer |
This is where DePIN connects to trust infrastructure. Your sensor stack generates data. Blockchain makes it verifiable. Together they create an unassailable property condition record.
Who's building: Effectively nobody at the protocol level. SmartRent and others do smart home, but not standards-grade attestation.
Layer 4: Reputation Registry (Agent/Owner Truth)
What it replaces: Zillow reviews, self-reported credentials, unverifiable track records.
| Component | Current | Blockchain Version |
|---|---|---|
| Agent track record | Self-claimed, gaming | Verified transaction count, outcomes |
| Owner history | Unknown until problems | Verifiable rental/payment history |
| Tenant reputation | Credit score + references | On-chain rental history |
| Contractor performance | Yelp reviews | Verified project completion |
Who's building: Early experiments in DeFi reputation (e.g., Spectral, Masa), but not real estate-specific.
The Integration Thesis
The layers compound when connected:
DePIN Sensors → Condition Registry
↓
Property Registry ← Ownership on-chain
↓
Listing Registry ← Market data unified
↓
Reputation Registry → Trust scores for all parties
↓
Tokenization → Tokens backed by verified truth
The insight: Tokenization without trust infrastructure is fragile. Tokens backed by verified, on-chain property records are antifragile.
This is the data flywheel with a trust layer:
- Sensors generate data (DePIN)
- Blockchain attests data (immutable)
- Verified data backs tokens (value)
- Tokens fund more sensors (growth)
Competitive Landscape
Who Controls What
| Layer | Incumbent | Threat Level | Blockchain Challenger |
|---|---|---|---|
| Ownership | County recorders, title cos | Low (fragmented, slow) | Propy, Medici, Ubitquity |
| Listings | NAR, Zillow, Redfin, MLSs | High (network effects) | None with traction |
| Condition | Inspectors, SmartRent | Low (no standard) | Gap — DePIN opportunity |
| Reputation | Zillow, Yelp | Medium (gaming) | Gap — DeFi reputation |
The NAR Factor
NAR (National Association of Realtors) controls MLS access and is currently:
- Facing massive antitrust litigation (Sitzer/Burnett verdict)
- Implementing Clear Cooperation Policy (CCP) that Zillow/Redfin are weaponizing
- In regulatory chaos
This creates opportunity. When incumbents are distracted by litigation and internal conflict, new entrants can build alternatives.
Strategic Positioning
Option 1: Own the Condition Layer (DePIN → Attestation)
The play: Deploy sensors, generate verifiable condition data, create the standard for property attestation.
| Advantage | Challenge |
|---|---|
| No incumbent owns this | Hardware deployment is hard |
| Compounds with existing sensor stack | Network effects take time |
| Insurance + lending demand exists | Need industry adoption |
First move: Partner with property managers already deploying sensors. Create attestation standard. Build the protocol.
Option 2: Own the Listing Layer (Decentralized MLS)
The play: Build an open, blockchain-based listing protocol that agents can use without MLS fees.
| Advantage | Challenge |
|---|---|
| Clear pain point ($500/mo+ MLS fees) | Massive network effects to overcome |
| NAR in chaos creates window | Zillow/Redfin will fight |
| International expansion easier | Regulatory complexity |
First move: Start with a jurisdiction that has clearer regulation (NZ, Singapore, UAE). Build traction. Expand.
Option 3: Own the Integration (Full Trust Stack)
The play: Build the protocol that connects all four layers — ownership, listings, condition, reputation.
| Advantage | Challenge |
|---|---|
| Winner-take-most if successful | Massive scope |
| Compounds all data moats | Requires partnerships across layers |
| Becomes the "title" of digital real estate | Capital intensive |
First move: Start with condition (lowest incumbent resistance), expand to reputation, then listings, then ownership.
The NZ/Singapore Opportunity
Both jurisdictions offer advantages for trust infrastructure:
| Factor | US | NZ/Singapore |
|---|---|---|
| Regulatory clarity | Fragmented (50 states) | Clear national framework |
| MLS structure | 800+ independent | More centralized |
| Government openness | Slow | Proactive (esp. Singapore) |
| Market size | Massive but complex | Smaller but coherent |
| First-mover risk | Higher (litigation) | Lower (regulatory support) |
The strategy: Prove the model in NZ/Singapore, then export to other markets with regulatory templates.
What Would Make This Work
Technical Requirements
- Standards-grade attestation protocol (property condition)
- Interoperability with existing land recording systems
- Privacy-preserving verification (ZK proofs for sensitive data)
- Oracle network for off-chain → on-chain data
- Token standards for property rights (ERC-3643 or similar)
Business Requirements
- First-mover property managers deploying sensors at scale
- Insurance partners willing to underwrite based on on-chain data
- Government or industry body endorsement for attestation standard
- Secondary market liquidity for tokenized properties
- Agent/broker adoption for listing protocol
Network Effects Required
| Layer | Critical Mass Threshold |
|---|---|
| Condition | 1,000+ properties with continuous attestation |
| Listings | 10,000+ active listings in one market |
| Ownership | Government adoption in 1+ jurisdiction |
| Reputation | 10,000+ verified transactions |

The Question
When property truth lives on-chain — ownership verified, condition attested, history complete, reputation portable — who needs title companies, MLS fees, or periodic inspections?
The infrastructure that verifies properties will be worth more than the infrastructure that lists them.
