emission package

Overview

Package emission manages GNS token emission and distribution for GnoSwap.

The emission system controls creation and distribution of new GNS tokens with a deflationary model featuring periodic halvings over 12 years.

Emission Schedule:

  • Year 1-2: 100% emission rate (225,000,000 GNS/year)
  • Year 3-4: 50% emission rate (112,500,000 GNS/year)
  • Year 5-6: 25% emission rate (56,250,000 GNS/year)
  • Year 7-8: 12.5% emission rate (28,125,000 GNS/year)
  • Year 9-12: 6.25% emission rate (14,062,500 GNS/year)

Distribution Targets (configurable via admin or governance):

  • LIQUIDITY_STAKER: Rewards for LP providers (default 75%)
  • DEVOPS: Development and operations fund (default 20%)
  • COMMUNITY_POOL: Community treasury (default 5%)
  • GOV_STAKER: GNS staking rewards (default 0%)

Key Functions:

  • MintAndDistributeGns: Mints and distributes GNS per emission schedule; returns false only when emission is halted.
  • SetDistributionStartTime: Sets or reschedules the start timestamp while it is still in the future; the timestamp is immutable once active.
  • ChangeDistributionPct: Updates distribution percentages
  • ClearDistributedToStaker/GovStaker: Resets pending distribution amounts

Function

ChangeDistributionPct

func ChangeDistributionPct( cur realm, liquidityStakerPct int64, devOpsPct int64, communityPoolPct int64, govStakerPct int64, )

ChangeDistributionPct changes distribution percentages for emission targets.

This function redistributes how newly minted GNS tokens are allocated across protocol components. Before applying new ratios, it distributes any accumulated emissions using the current ratios, ensuring emissions are distributed according to the ratios in effect when they were generated. This prevents retroactive application of new ratios to past emissions.

Parameters:

  • cur: Current realm context; callers use cross(cur) when crossing into this realm.
  • liquidityStakerPct: percentage for liquidity stakers in basis points (100 = 1%, 10000 = 100%).
  • devOpsPct: percentage for DevOps in basis points (100 = 1%, 10000 = 100%).
  • communityPoolPct: percentage for the community pool in basis points (100 = 1%, 10000 = 100%).
  • govStakerPct: percentage for governance stakers in basis points (100 = 1%, 10000 = 100%).

Requirements:

  • Percentages must sum to exactly 10000 (100%).
  • Each percentage must be between 0 and 10000 inclusive.

Example:

Example
1ChangeDistributionPct(
2  7000,  // 70% to liquidity stakers
3  2000,  // 20% to devops
4  1000,  // 10% to community pool
5  0,     // 0% to governance stakers
6)

Only callable by admin or governance.
