Solana staking is where SOL holders contribute to the network's consensus process by delegating their coins to validators, securing the network and earning rewards. It’s part of Solana's proof-of-stake system, providing passive income for staked tokens.

As a Solana staker, you'll receive additional SOL tokens as rewards.

MEV stands for «Maximum Extractable Value" and pertains to the additional profits a block producer can earn by manipulating transaction inclusion and order. This includes capturing arbitrage opportunities and optimizing trade order for extra gains.

Jito is an advanced MEV infrastructure for Solana validators and is designed to maximize profits from MEV opportunities while reducing network spam. Its features include off-chain blockspace auctions and efficient reward distribution.

Staking rewards on Solana are distributed at the end of each epoch, about every two days, and are credited directly to your stake account.

You can generally unstake your SOL at any time using most wallets and services but must wait until the current epoch ends to access them (cool-down period). For immediate access, services like unstake.it or marinade.finance offer unstaking without waiting.

Marinade Finance allows staking SOL and receiving mSOL tokens in return, which can be used in various DeFi platforms while continuing to earn staking rewards. It enhances your DeFi options by simultaneously staking and investing in other projects.
