Within the Fractal Network, the BRC-20 swap module is already active. Liquidity providers can earn additional token rewards through PizzaFarm, a process commonly known as LP mining. We are currently developing a non-custodial BRC-20 module within the Fractal Network to further support this.

## Pizza Farm&#x20;

PizzaFarm will serve as the frontend interface for this module, allowing liquidity providers on PizzaSwap to earn additional rewards through the platform.

## How does PizzaFarm work?

In version 1 (V1), we have completed the development of the staking chain index, primarily used to calculate LP shares and distribute reward tokens to liquidity providers.

## Staking Mechanism

### Linear Vesting

Token linear vesting usually means releasing a certain amount of tokens at a constant rate over a period of time. This linear vesting mechanism ensures transparency and fairness in token distribution, commonly used for token lock-up schedules, team rewards, or liquidity mining rewards.

#### `Reward Formula`

$$
R\_u(t) = (\frac{L\_u}{L\_{total}})\times(\frac{T\_{total}}{T\_{end} - T\_{start}})\times(t-T\_{start})
$$

## Staking Index

The index code references Uniswap's staking standards, which are the foundational framework for calculating LP shares and distributing rewards. You can learn more and explore the details here:
