SRU Engine

Standardized Revenue Unit (SRU) Generation System

Global Mobility Income → Unified On-Chain Value

---

🚀 Introduction

The SRU Engine is one of the core components of the Ridera Protocol. It transforms real-world mobility earnings—sent by riders, couriers, and fleet operators—into a single, comparable, standardized metric called SRU (Standardized Revenue Unit).

SRU allows Ridera to normalize global earnings across:

• 195+ countries

• multiple mobility platforms

• various work categories

• different currencies

• economic patterns and cost-of-living differences

It ensures fair representation of real-world work and provides a unified basis for on-chain yield distribution.

🎯 Purpose of the SRU Engine

The SRU Engine solves critical problems in global mobility income:

• Huge variation in earnings across countries

• Different payout structures across platforms

• Irregular work patterns (full-time, part-time, peak-only)

• Currency and purchasing power differences

• High volatility in bonus structures

SRU standardizes all of this into a universal measurement, enabling transparent and fair yield distribution.

🔷 1. Inputs to the SRU Engine

The SRU Engine receives structured data:

Earnings Data

• total payout

• base fare

• bonuses

• surge income

• tips

• platform metadata

Economic Metadata

• worker region

• currency

• mobility platform

• worker category

• timestamp (cycle period)

Oracle Verification Flags

• validated = true

• no-duplicate

• no-anomaly

• trust-score adjustment

Only validated earnings are processed.

🔷 2. Weighting System

SRU computation relies on a three-layer weighting model that ensures fair global normalization.

2.1 Country / Region Weight

Accounts for:

• cost of living

• average delivery/ride income

• regional economic strength

• purchasing power

Example (illustrative):

India → 1.00x
Vietnam → 0.95x
Philippines → 0.98x
UAE → 1.40x
USA → 1.80x

2.2 Platform Weight

Each platform has different payout structures.

Uber Eats → 1.20x
DoorDash → 1.15x
Zomato → 1.00x
Swiggy → 0.95x
Grab → 1.10x

2.3 Work Category Weight

Based on work intensity:

/Full-time (8–10 hrs) → 1.20x
Part-time (4–6 hrs) → 1.00x
Peak-only → 1.10x
Low-activity areas → 0.90x

All weights are dynamic and updated as the ecosystem grows.

🔷 3. SRU Formula

The SRU Engine applies the following formula:

SRU = Earnings_USD × CountryWeight × PlatformWeight × CategoryWeight

Properties:

• Region-normalized

• Platform-consistent

• Fair for all worker types

• Resistant to manipulation

SRU is always proportional to real earnings, but adjusted for global fairness.

---

🔷 4. Daily Cycle Creation (Batching)

The SRU Engine groups all computed SRUs into a 24-hour cycle:

Each cycle includes:

• total SRU

• individual SRU per user

• platform breakdown

• region metadata

• timestamp

• Merkle root

Cycles ensure consistent, predictable yield periods.

---

🔷 5. Merkle Root Generation (For Proof Registry)

The SRU Engine sends batch data to the Batcher:

• All SRUs hashed

• Merkle tree constructed

• Merkle root created

• Root + metadata sent on-chain

The Proof Registry stores:

• cycleId

• merkleRoot

• totalSRU

• timestamp

This ensures transparency and auditability.

---

🔷 6. Output of the SRU Engine

The final outputs are:

Per-user SRU

Used for:

• contribution weighting

• worker analytics

• future reputation score system

Total SRU (Cycle Level)

This is the number used by the Yield Vault to calculate daily RDR emissions.

Merkle Root

Used for proof verification on-chain.

🔥 Why SRU Makes Ridera Unique

SRU enables Ridera to:

✔ Tokenize human productivity

✔ Create globally fair yield

✔ Normalize global earnings into a single metric

✔ Maintain transparency and immutability

✔ Support decentralized workforce identity

✔ Enable future credit systems based on work

SRU is the world’s first universal on-chain measure of mobility work.
