What VGPI measures
The Vexidus Global Productivity Index (VGPI) is a weighted composite tracking the combined productive output of the world’s measurable economies, denominated in VGD (Vexidus Global Dollar).
It is designed as a neutral reference — no human editorial input, no discretionary weighting. The index recomputes continuously from primary-source economic data.
Index formula
Every input is hashed; every output carries a computation_hash and input_hash so any observer can verify the snapshot matches the inputs.
Economy Wellness Score (EWS)
Each constituent economy receives an EWS (0–100) combining four sub-scores, each 0–100:
- Trade: imports + exports as share of GDP — openness to global commerce
- Productivity: GDP per capita relative to global median
- Stability: inflation volatility, currency drawdown, sovereign-spread proxy
- Demand: consumption as share of GDP — depth of internal market
Health tiers: strong (≥75), moderate (60–74), developing (45–59), stressed (30–44), crisis (<30).
Data sources
Verification
Every snapshot returned by the engine carries two hashes so third-party observers can confirm integrity without trusting Vexidus:
input_hash— BLAKE3 of the canonical-ordered input bundle (GDP vector, rate vector, weights)computation_hash— BLAKE3 of the full output bundle, committed in the snapshot itself
Update cadence
- Forex rates: refreshed every 60 seconds from upstream feeds
- Crypto VWAP: refreshed every 60 seconds
- GDP base: refreshed when upstream publishes (quarterly/annual per country)
- VGPI recomputation: every 30 seconds; broadcast via WebSocket to connected clients
What VGPI is not
- — It is not a price. It is a productivity index.
- — It is not backed by any asset or commitment.
- — It is not investment advice. Figures are reference data; use with appropriate diligence.
- — It is not infallible. Upstream data quality bounds every output; sovereign data can lag or be revised.
