/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

MintAndDistributeGns

func MintAndDistributeGns(cur realm) (int64, bool)

MintAndDistributeGns mints and distributes GNS tokens according to the emission schedule.

This function is called automatically by protocol contracts during user interactions to trigger periodic GNS emission. It mints new tokens based on elapsed time since last distribution and distributes them to predefined targets (staker, devops, etc.).

Returns:

  • int64: Total amount of GNS distributed in this call

Note: Distribution only occurs if start timestamp is set and reached. Any undistributed tokens from previous calls are carried forward.
