Sub-Volume B: Global Reserve Unit (GRU) Integration

Overview

The Global Reserve Unit (GRU) Integration integrates the GRU monetary system into DBIS' omniversal framework with hierarchical structure and XAU-anchored valuation.

GRU Hierarchy

Defined Ratios

• 1 M00 GRU = 5 M0 GRU
• 1 M00 GRU = 25 M1 GRU
• 1 M00 GRU = x M0 GRU + y M1 GRU (mixed composition)

Unit Types

• M00: Base unit (highest tier)
• M0: Intermediate unit (1 M00 = 5 M0)
• M1: Lowest unit (1 M00 = 25 M1, 1 M0 = 5 M1)

GRU Asset Valuation

All triangulations occur through XAU (gold), anchoring GRU to:

• Fiat currencies (USD, EUR, etc.)
• Commodities (Silver, Platinum, Oil, etc.)
• CBDC (Central Bank Digital Currencies)
• Tokenized assets (Security tokens, etc.)

Valuation Formula

GRU Value = XAU Value × Triangulation Rate

Base rate: 1 GRU M00 = 1 oz XAU (troy ounce)

GRU Bond Systems

GRU-Linked Bonds

Two bond types are supported:

• Li99PpOsB10: 99-year bond with 10% interest (one-time structure)
• Li99PpAvB10: 99-year bond with 10% average interest

Bond Features

• Principal amount in GRU
• Fixed or variable interest rates
• Coupon payments
• Maturity date calculation
• Automatic redemption at maturity

GRU Liquidity Loop

Atomic Transaction Loop

The GRU liquidity loop executes atomic transactions until a target value is reached:

7 → 10 GRU → 9.55 (net after FX)

Process:

1. Start with initial amount (e.g., 7 GRU)
2. Execute atomic transaction via GAS network
3. Apply FX cost (e.g., 4.5%)
4. Calculate net value (e.g., 9.55)
5. Re-run until target value reached or max iterations

Loop Parameters

• initialAmount: Starting GRU amount
• targetAmount: Target GRU amount
• targetNetValue: Target net value after FX
• maxIterations: Maximum loop iterations (default: 10)

Example Usage

import { gruService } from '@/core/monetary/gru/gru-service';
import { gruValuationService } from '@/core/monetary/gru/gru-valuation.service';

// Convert GRU units
const conversion = await gruService.convertGruUnits({
  unitType: 'M00',
  amount: '10',
  targetType: 'M0',

// Result: 50 M0 (10 M00 × 5)

// Calculate valuation
