Staking is when users lock up their assets to ensure the functionality and security of the blockchain. In return, the owners of the asset are rewarded by the blockchain.
Staking Solana is a safe and passive way to earn more Solana. By staking, you are keeping the network secure, decentralized, and earning rewards for it. For example, you can stake 100 Solana and in return, you can expect to have up to 7% more Solana every year from staking rewards.
