Algorithmic Integrity & Data Provenance

How we verify 25,264 real estate broker credentials against official government records.

The Verification Objective

The ren.ph Data Engine, architected by GodMode.ph, serves to bridge the transparency gap in the Philippine Real Estate sector.

Our mission is to provide a 1:1 mapping of digital profiles to the Professional Regulation Commission (PRC) licensure records, ensuring that every professional listed on this platform possesses a verifiable history of licensure.

The Verification Methodology

We employ a multi-tiered Agentic AI orchestration to ingest, parse, and validate professional credentials. The "Trust Chain" is divided into two primary categories:

Tier 1: Direct PRC Provenance

97.7% Coverage (24,689 brokers)

Data is extracted directly from official .gov.ph sources, including PDF board results and official PRC announcements. This represents the highest level of probabilistic truth.

  • Direct PRC-hosted PDFs (2011-2017)
  • Google Drive PDFs linked from PRC articles (2019-2025)
  • Official PRC announcement pages

Tier 2: Cross-Referenced Integrity

2.3% Coverage (575 brokers)

In instances where the PRC has not maintained a digital permanent record (e.g., specific legacy or SPLE exams), our engine utilizes secondary registries and third-party board result mirrors.

  • Explicitly flagged in schema for transparency
  • Cross-validated against multiple sources
  • Example: April 2022 exam (post-COVID resumption)

Technical Governance

The integrity of this dataset is managed through:

1

Programmatic Validation

Automated scripts verify license numbers against batch-specific passer lists from official PRC examination records.

2

Source Citation

Every profile contains an isBasedOn schema attribute pointing to the specific document used for validation, creating a verifiable trust chain.

3

Architectural Accountability

Led by the Principal CTO of GodMode.ph, ensuring that the data engine operates with zero-hallucination constraints regarding professional identities.

Schema Transparency

Each broker profile includes structured data (JSON-LD) with:

  • hasCredential — The professional license claim
  • subjectOf: CheckAction — The verification performed by ren.ph Data Engine
  • isBasedOn — Direct link to the evidence (PRC source or third-party)
