In proof-of-stake, validators risk or stake coins to compete to be randomly selected to validate transactions and are rewarded for performing their responsibilities and behaving in accordance with protocol rules. Malfunctions that cause validators to go offline and, in turn, inhibit them from performing their duties, can result in financial penalties (e.g., inactivity leak). Any malicious activity, such as validating multiple blocks for the same slot, making incorrect attestations or otherwise violating protocol rules, results in the penalization or in extreme cases slashing of staked coins and forced exit from performing validator duties. The penalty varies depending on the type of offense and correlation to potential offenses by other validators.

Validators range from SOL enthusiasts to professional operations that design and build dedicated machines and data centers, including “clusters,” which are groups of validators that act cohesively and combine their processing to confirm transactions. On the Solana network, a validator does not have any minimum staking requirement in order to participate in maintaining the network. When a validator confirms a transaction, the validator and any associated stakers receive fees, including a base fee and a discretionary tip. During the course of ordering transactions and validating blocks, validators may be able to prioritize certain transactions in return for increased transaction fees, an incentive system known as “Maximal Extractable Value” or MEV. For example, in blockchain networks that facilitate DeFi protocols in particular, such as the Ethereum network, users may attempt to gain an advantage over other users by increasing offered transaction fees to incentivize validators to give their submitted transaction requests priority. Validators less commonly capture MEV in the Solana network because, unlike the Ethereum network, it does not publicly expose transactions before they are accepted by a validator. However, some efforts are underway to help Solana Validators consistently capture MEV.
