# Farming

1. Farm have `total_reward`, `start_block` and `reward_per_block` 

2. Farm start with `acc_token_per_share` is 0 and `last_reward_block` is block where Farm has been

   created

3. Every action of Farmer will update Farm

4. Update farm will update `acc_token_per_share` and `last_reward_block`

5. Update farm by:

    - Get `lp_supply` = balance_of (Farm lp token address)

    - `acc_token_per_share` = (`block now` - `last_reward_block`) * `reward_per_block` / `lp_supply`

    - `last_reward_block` is block where Farm was update

6. Farmer can `deposit` lp token, when Farmer call `deposit`, flow is:

    - Update Farm with rule was defined at step 5

    - `amount` amount of deposit

    - `last_reward` = `amount` * `Farm.acc_token_per_share`

7. Farmer can `claim` lb token, when Farmer call `claim`, flow is:

    - Update Farm with rule was defined at step 5

    - Calculate reward = `Farmer.amount` * `Farm.acc_token_per_share` - `Farmer.last_reward`

    - `Farmer.last_reward` = `Farmer.amount` * `Farm.acc_token_per_share`
