Solution

Here you can find abrief overview of how Filstake pools workFilstake consists of three main components:1. Liquid Staking Pool contract. This contract issues stFIL tokens in exchange for FIL tokens deposited by a user. stFil is an yield-bearing token.2. Pool Manager. Off-chain worker + on-chain contract that can accept new miners and propose interest rate to them based on their performance3. PoolLoanContract. This contract is created by Pool Manager for every loan approved for a miner. After it gets access to the Miner's actor Owner account and Beneficiary account, a loan amount can be pulled from Pool Contract by a Miner, so he'll be able to use it as an Initial Pledge Collateral.
