Switzerland-based JPool lets users stake SOL and participate in the consensus mechanism of the Solana network for rewards. When users stake SOL via JPool to become delegators, they receive the JSOL token, which represents their ownership in the pool and grows as it accrues staking rewards. JSOL can also be used as a DeFi instrument for liquidity mining. Delegators can earn staking rewards of up to 6.5-8% annually JPool distributes SOL staked by delegators among all validators to maximize rewards and keep the network decentralized. It uses the Stake Pool concept, which increases stake distribution among validators to strengthen decentralization.
