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

SetDistributionStartTime

func SetDistributionStartTime(cur realm, startTimestamp int64)

SetDistributionStartTime sets the timestamp when emission distribution starts.

This function controls when GNS emission begins. Before the configured timestamp is reached, an admin or governance caller may reschedule it. Once the timestamp is reached, the start time is immutable.

Parameters:

  • cur: Current realm context; callers use cross(cur) when crossing into this realm.
  • startTimestamp: positive future Unix timestamp when emission should begin.

Requirements:

  • Must be called before distribution starts.
  • Timestamp must be in the future and leave room for the 12-year schedule.

Effects:

  • Sets global distribution start time.
  • Initializes GNS emission state if not already started.
  • Emission begins automatically when timestamp is reached.

Only callable by admin or governance.
