Growth Stability Index

The Growth Stability Index (GSI) adjusts the configured rates of Atto distribution programmes that use it. The current GSI is 0.1. A programme's configured base rate is multiplied by this value.

Release pacing, not a price target

The GSI changes how quickly Atto is released. It is not a peg and does not promise a particular price or market outcome.

How it works​

The GSI ranges from a configured minimum, typically 0.10, to 1.0. It compares Atto's recent market position using three price measures:

  • 7-day average price: Smooths out short-term price movements
  • All-time high (ATH): The highest recorded Atto price
  • 1-month low: The lowest price in the past 30 days

Formula​

GSI = (7-Day Average Price - 1-Month Low) / (ATH - 1-Month Low)

The result places the 7-day average between the 1-month low and the all-time high:

  • GSI near 0: The average is close to the 1-month low
  • GSI near 1: The average is close to the all-time high

Asymmetric adjustment​

The GSI responds faster when its target falls than when it rises:

  • Lower target: The lower value is applied on the next update
  • Higher target: The GSI can increase by no more than 0.01 per update

This lets a distribution rate fall quickly after lower price readings, while returning more gradually after higher readings.

Example​

Suppose the current GSI is 0.50 and the next target is 0.80. Rather than jumping straight to 0.80, it rises in steps:

  • Update 1: 0.50 → 0.51
  • Update 2: 0.51 → 0.52
  • ... and so on

If a later price reading produces a target of 0.30, the lower target is applied on the next update: 0.52 → 0.30.

Effect on distribution​

The full 18 billion ATTO supply was created at genesis. The GSI does not create new ATTO; it changes how quickly part of that existing supply enters circulation through programmes that use it.

  • Higher GSI: Rates can move closer to their configured base rates
  • Lower GSI: Rates are scaled down further

The aim is to limit additional sell pressure from distribution when market conditions are weak. The slower upward adjustment also slows the return to the full configured rate after a rise.
