Every 12 seconds, one block is added when the system is running optimally. Validators do need to be roughly synchronized with time. A slot is like the block time, but slots can be empty. The Beacon Chain genesis block is at Slot 0. While proof-of-work is associated with miners, Ethereum’s validators are proof-of-stake “virtual miners”. Validators run Ethereum’s consensus. Their incentives are discussed later in Staking Rewards and Penalties. A block proposer is a validator that has been pseudorandomly selected to build a block. Most of the time, validators are attesters that vote on blocks. These votes are recorded in the Beacon Chain and determine the head of the Beacon Chain. At ev
