The Complete Stack
Why DeedLock Exists
Addressing fraud, verification speed, compliance, and tokenization requirements
Reduce Title Fraud
DeedLock helps detect tampered documents and mismatched records by anchoring proof fingerprints to a public, verifiable registry trail.
Instant Verification
Banks, regulators, and buyers can verify certificate status (valid/revoked/expired) without manual calls, emails, or paperwork chains.
Audit & Compliance Ready
Proofs include issuer identity, standard version, timestamps, and on-chain anchors—supporting repeatable compliance workflows and audits.
Tokenization-Ready Properties
DeedLock proofs act as a documentation gate for PRC Protocol: tokenization requires IRP-certified property documentation.
What DeedLock Covers (IRP-2xx Scope)
Standards for multiple aspects of real-estate documentation
Title & Ownership
Proofs that represent ownership claims and supporting title documentation under versioned IRP standards.
Encumbrances & Liens
Standardized representation of liens, charges, or restrictions (future IRP-2xx extensions).
Tenancy & Occupancy
Tenancy/occupancy assertions where applicable (future IRP-2xx extensions).
Project & Developer Approvals
Approvals, NOCs, and development documentation needed for legitimate listings and financing workflows.
Registry Issuance & Updates
Issue, update, and revoke proofs while preserving an auditable trail.
Note: Exact standard definitions and schemas are published on IRP Registry. This page provides an overview and integration context.
IRP-210 — DeedLock Title Security
The foundational standard for property title verification. IRP-210 defines how title documents are hashed, packaged, and verified — establishing the root of trust for real-estate markets.
What IRP-210 Proves:
- Property identifier
- Issuer identity & accreditation
- Issuance timestamp
- On-chain anchor reference
- Verification & revocation status
Why IRP-210 is First:
Title is the root of trust for real-estate markets. Without verifiable title documentation, tokenization, financing, and cross-border transactions carry excessive risk. IRP-210 provides the cryptographic foundation.
How DeedLock Verification Works
From proof issuance to instant verification by any party
Issuer Creates the Proof
An approved issuer (registry, authority, bank, or authorized platform) prepares property documents and metadata.
CertiCore Packages & Hashes
PRC CertiCore™ generates cryptographic fingerprints and creates an IRP-compliant proof package (e.g., IRP-210).
Anchor on PRC Network
A minimal on-chain anchor is recorded on PRC Network, creating a tamper-evident timestamped reference.
Anyone Can Verify
Relying parties verify integrity, standard version, issuer identity, and proof status (valid/revoked/expired) instantly.
Verification Trust Signals
Anchored on PRC Network
