JPool is a stake pool on the Solana blockchain network enabling safe, secure, high-yield rewards on your staked SOL. It represents the holder's share of the total staked funds in the pool. When you delegate your SOL to a Stake Pool, you get JSOL tokens in return. These tokens are your proof of a share ownership in the stake pool, and they can be traded back for SOL at the end of any epoch. Obviously, you get more SOL than you staked in the first place, including your APY accrued over the staking period. When staking, each delegator may participate in determining the Pool's general disposition in terms of the importance of higher APR vs. good of the network.
