# Ethereum

ETH holders can activate validator software by staking at least 32 ETH. By doing this, they take on the role of a validator and assume responsibilities surrounding data storage, transaction processing, and adding blocks to the blockchain. The validators contribute to Ethereum's security, all while earning additional ETH as rewards.
