Delegators earn rewards for participating in staking (either pledging or delegating), and these rewards are automatically distributed between the participants according to the rewards scheme. The rewards scheme in Cardano is designed to be decentralized, which means that there is no single controlling party. These rewards are auto-generated by the protocol itself, and are not managed by the stake pool operators (SPOs).

Stake pools offer several benefits for stakers, including increased decentralization of the network and potentially higher rewards due to the pool's larger stake. By participating in a stake pool, you can delegate your stake to a stake pool operator who is responsible for maintaining the pool and validating transactions on the network. This can make it easier for individual stakers to earn rewards, as they do not need to set up and maintain their own staking infrastructure.

Cardano is a decentralized third-generation proof-of-stake blockchain platform and home to the ada cryptocurrency. It has been designed from the ground up by a team of top engineers and academic experts. Cardano has a strong focus on sustainability, scalability, and transparency and is a fully open source project that aims to deliver an inclusive, fair, and resilient infrastructure for financial and social applications on a global scale.
