Executive Summary

50+

Government information systems across ministries and agencies, each with own data standards

Problem Statement:

Ukrainian government operates 50+ information systems across ministries, agencies, and local governments-each with own data standards, update cycles, and access controls. Critical data (citizen identities, business registrations, property records, tax status) is duplicated across systems, creating inconsistencies: Person A is "deceased" in Tax Register but "active" in Pension Fund, Company B is "dissolved" in State Register but still receiving government contracts.

ETHRAEON Solution:

A governance layer that synchronizes authoritative data updates across agencies, generating cryptographic evidence when data conflicts arise. This is NOT a master data repository (each agency retains own database)-it's the integrity verification layer that proves data consistency and flags discrepancies for resolution.

Core Value: Enable "write once, trust everywhere" data sharing. When Ministry A updates critical record (e.g., business license status), Ministry B automatically sees update and can trust its authenticity-because ETHRAEON cryptographically verifies the source and timestamp.

Data Inconsistency Examples

⚰️ Identity Fraud

Issue: Person registered as "deceased" in Death Registry but "active" in Tax database

Impact: Deceased person's identity used to collect benefits or open bank accounts

Solution: ETHRAEON propagates death record update to all consuming systems within 24hrs

Procurement Fraud

Issue: Company "liquidated" in Unified State Register but still listed as "active contractor" in ProZorro

Impact: Blacklisted contractors continue government contracting via dissolved entities

Solution: USR liquidation status synced to ProZorro, bids auto-rejected

Property Disputes

Issue: Land Register shows Owner A, but local tax office shows Owner B

Impact: Conflicting ownership records lead to lengthy court cases

Solution: ETHRAEON flags conflict, initiates resolution workflow with both agencies

Employment Status

Issue: Person registered as "unemployed" in Employment Service but receives salary in Tax database

Impact: Welfare fraud OR data lag (legitimate employment not updated)

Solution: Cross-check employment status across Tax + Social Security + Employment Service

Authoritative Source Registry

Core Concept: For each data type, designate ONE authoritative source-the system that "owns" that data and is responsible for keeping it current.

Data Type Authoritative Source Consuming Systems Update Frequency
Business Registration Unified State Register (USR) ProZorro, Tax, Customs, Banking regulators Real-time (API push on change)
Citizen Death Records Civil Registry (Ministry of Justice) Tax, Pension Fund, Social Services, Banking Within 24 hours of registration
Property Ownership State Register of Real Property Rights Local tax offices, Notaries, Courts Real-time (on deed registration)
Tax Compliance Status State Tax Service ProZorro (contractor verification), Banking, Customs Monthly (compliance updates)
Employment Status State Tax Service (payroll data) Pension Fund, Employment Service, Social Services Monthly (payroll reporting cycle)
Criminal Convictions Unified Register of Pre-trial Investigations Police, Courts, Border Service, ProZorro (background checks) Real-time (on court verdict)

Data Synchronization Architecture

Update Propagation Flow

  1. Authoritative Source Updates Record: Ministry A changes critical data (e.g., business liquidation)
  2. ETHRAEON Evidence Node Created: SHA-256 hash of updated record + timestamp + source identity
  3. Notification Broadcast: All consuming systems notified (API webhook OR polling)
  4. Consuming Systems Update: Ministry B pulls update, applies to local database
  5. Confirmation Evidence: Ministry B emits confirmation node (acknowledges receipt + timestamp)
  6. Integrity Verification: ETHRAEON compares hashes-if consuming system's record matches authoritative source, integrity verified ✓

Conflict Detection

If consuming system's data does NOT match authoritative source after update notification:

Fraud Detection Use Cases

1. Identity Fraud Prevention

Scenario: Criminal attempts to open bank account using deceased person's identity

ETHRAEON Detection:

2. Procurement Fraud Prevention

Scenario: Blacklisted contractor creates new company, bids on government contract

ETHRAEON Detection:

3. Welfare Fraud Detection

Scenario: Person claims unemployment benefits while secretly employed

ETHRAEON Detection:

Pilot Deployment Framework

Phase Scope Duration Success Metric
Phase 1: 2-System Sync USR (business registry) ↔ ProZorro (procurement) 8 weeks 100% liquidation status sync, <1hr latency
Phase 2: Multi-System 5 data types (business, death, property, tax, employment), 10 agencies 20 weeks Detect 10+ fraud cases via cross-agency data checks
Phase 3: National Scale All 50+ government systems, full data synchronization 40 weeks eGovernment benchmark compliance (EU accession requirement)

Economic Model

Key Partners

Constitutional Controls

Integration: Diia eGovernment Platform

ETHRAEON complements Diia:

Example: Citizen requests "Certificate of No Criminal Record" via Diia. ETHRAEON verifies that Police, Courts, and Prosecutor databases all show consistent record before certificate issued.

EU Accession Alignment

EU Requirement: Candidate countries must demonstrate interoperable eGovernment systems (Chapter 10: Information Society and Media)

Next Steps

  1. Pilot System Selection: USR + ProZorro (high-impact fraud prevention use case)
  2. Ministry Coordination: MoU with Ministry of Justice (USR owner) + Ministry of Economy (ProZorro oversight)
  3. API Integration: Technical specs for authoritative source APIs (8-week development timeline)
  4. Deployment: Phase 1 live with 100% business liquidation status sync
  5. Evaluation: Fraud detection audit (measure procurement fraud reduction)
  6. Scale Planning: Roadmap for adding 5 additional data types (death records, property, tax, employment, criminal records)
