# Payout Pools

### Overview

Horizon implements two dedicated payout pools designed to reward irreversible, conviction-based actions within the protocol:

* **Burn-to-Earn Pool**
* **Forfeit-to-Earn Pool**

Both pools distribute Nova emissions to participants who permanently remove tokens from circulation or relinquish future claims. These mechanisms convert sacrifice into pro-rota rewards.

Payout pools are not staking systems. They do not involve deposits, withdrawals, or redeemable principal.

***

### Pool Types

#### Burn-to-Earn Pool

The Burn-to-Earn Pool rewards users who permanently burn Horizon or Nova.

* Tokens are irreversibly destroyed at entry
* Burned value is removed from total supply
* Participants receive a pro-rata share of Nova emissions allocated to the pool
* Participation is non-reversible and non-transferable

Burning represents a direct, permanent reduction in circulating supply and is treated as a high-conviction action.

***

#### Forfeit-to-Earn Pool

The Forfeit-to-Earn Pool rewards users who voluntarily forfeit future claims.

Participants may forfeit:

* Horizon miners
* Unclaimed Nova rewards

Key properties:

* All forfeited inputs are denominated in USD at the time of forfeiture
* Forfeited assets are sent to the Horizon Treasury
* Forfeiture permanently removes the participant’s future claim on the forfeited assets
* Participants receive Nova emissions based on forfeited value and time commitment

Forfeiture converts unrealised or future value into immediate participation weight.

***

### Position-Based Accounting

Participation in either payout pool creates a **non-transferable position** representing reward entitlement over time.

Each position records:

* Pool type (Burn-to-Earn or Forfeit-to-Earn)
* Asset forfeited or burned
* USD value at entry (for share calculation)
* Effective shares
* Entry timestamp and epoch
* Minimum commitment period
* Reward accrual status
* Claimable rewards

Positions:

* Have no redeemable principal
* Cannot be exited early
* Exist solely to track accrual and claims

***

### Epoch Structure & Settlement

#### Weekly Epochs

Both payout pools operate on **fixed-length weekly epochs**.

* Epoch duration: **7 days**
* Rewards accrue continuously and pro-rata within the epoch
* No rewards are claimable mid-epoch
* Accrued rewards are finalized at epoch completion

#### Staggered Settlement

To reduce congestion and behavioural clustering, payout pools are staggered.

* Each pool has an independent epoch anchor
* Epoch length remains constant across pools
* Settlement occurs on different fixed days

Example:

* Forfeit-to-Earn settles weekly
* Burn-to-Earn settles weekly, offset by several days

This staggering smooths reward realization without increasing complexity or risk.

***

### Reward Accrual & Distribution

#### Pro-Rata Accrual

Rewards accrue linearly over time based on **time-weighted effective shares**.

Accrual is proportional to:

* Effective shares assigned at entry
* Duration active within the epoch

Late entry earns proportionally less for that epoch. There is no advantage to timing entry near settlement.

#### Epoch Settlement

At epoch end:

* Total pool emissions are finalized
* Each position’s share is calculated
* Rewards become claimable

Unclaimed rewards remain claimable indefinitely after settlement.

***

### Commitment & Irreversibility

Participation in payout pools is subject to enforced commitment periods.

* Positions cannot be cancelled
* Principal is never returned
* No early exit is permitted
* Rewards accrue only while the position is active and locked

This design prevents:

* Timing attacks
* Capital cycling
* Short-term exploitation of emission schedules

***

### Emission Source

Each payout pool receives a fixed percentage of Nova emissions from the Nova Emission Pool.

* Emissions are deterministic and protocol-defined
* Allocation is fixed at genesis
* User behaviour affects distribution, not issuance

***

### Security & Auditability

Payout pools are designed for simplicity and transparency.

* No elastic supply
* No per-block reward logic
* No oracle-dependent emissions
* Deterministic epoch accounting
* Fully auditable position states

***

### Summary

Payout pools transform irreversible actions, burning and forfeiting, into predictable, time-weighted Nova rewards.

They:

* Reward conviction over speculation
* Enforce commitment through irreversibility
* Distribute emissions fairly and deterministically
* Strengthen long-term protocol alignment

Payout pools are a core component of Horizon’s incentive architecture, converting sacrifice into sustainable rewards.
