LP-820: Network Energy Transparency

Abstract

This LP establishes the transparency standards for reporting Lux Network's energy consumption and environmental metrics. It defines what data is published, how it's calculated, where it's displayed, and how stakeholders can verify claims.

Motivation

Sustainability claims without transparency are worthless. Stakeholders increasingly demand:

  1. Real-time visibility - Not just annual reports, but live metrics
  2. Methodology disclosure - Understanding how numbers are calculated
  3. Independent verification - Ability to audit claims
  4. Comparable formats - Metrics that enable cross-network comparison

This LP transforms Lux Network's environmental performance from a black box into a transparent, verifiable system. It builds the trust foundation necessary for institutional adoption and regulatory compliance.

Transparency Principles

  1. Complete: Report all material energy consumption
  2. Accurate: Use best available data and methods
  3. Comparable: Enable comparison with other networks
  4. Timely: Publish data regularly and promptly
  5. Accessible: Make data easy to find and understand

Calculation Methodologies

Network Power Consumption

Bottom-Up Method (Primary):

P_network = Σ(P_validator_i) for all active validators

Where:

  • P_validator_i = Reported or estimated power per validator

Estimation for Unreported Validators:

  • Cloud validators: Use instance type power estimates
  • Bare metal: Use hardware TDP × 0.5 utilization factor
  • Unknown: Use network average

Top-Down Method (Verification):

P_network = N_validators × P_average × (1 + overhead)

Where:

  • N_validators = Active validator count
  • P_average = Average power from survey
  • overhead = 10% for networking/storage

Energy Per Transaction

E_tx = (P_network × T_block) / N_tx_block

Where:

  • P_network = Network power (kW)
  • T_block = Block time (seconds)
  • N_tx_block = Transactions in block

Finality-Adjusted:

E_tx_final = E_tx × (1 / finality_probability)

For Lux (deterministic finality): finality_probability = 1.0

Carbon Intensity

I_carbon = E_tx × EF_network × (1 - R_network)

Where:

  • E_tx = Energy per transaction (kWh)
  • EF_network = Weighted average emission factor
  • R_network = Renewable energy fraction

Emission Factor Calculation:

EF_network = Σ(EF_region_i × E_region_i) / Σ(E_region_i)

Weighted by energy consumption per region.

Comparison Framework

Cross-Network Comparisons

When comparing Lux to other networks:

  1. Normalize by finality: Account for different confirmation requirements
  2. Use consistent boundaries: Same scope of emissions
  3. Note methodology differences: Transparent about calculation variations
  4. Update regularly: Use most recent data for all networks
