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 governance):

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

Key Functions:

  • MintAndDistributeGns: Mints and distributes GNS per emission schedule
  • SetDistributionStartTime: One-time setup of emission start timestamp
  • ChangeDistributionPct: Updates distribution percentages
  • ClearDistributedToStaker/GovStaker: Resets pending distribution amounts

Function

SetOnDistributionPctChangeCallback

func SetOnDistributionPctChangeCallback(cur realm, callback func(cur realm, emissionAmountPerSecond int64))

SetOnDistributionPctChangeCallback sets a callback function to be called when distribution percentages change. This allows external contracts (like staker) to update their internal caches when governance changes emission rates.

Only callable by the staker contract.
