However, a validator is not usually a block proposer, so their maximum reward is 64-8 /64 * base_reward = 7/8 * base_reward. A validator that has made timely source, target and head votes, proposed a block and participated in a sync committee could receive 64/64 * base_reward = base_reward. The reward is calculated as the sum of the applicable weights divided by 64. This is calculated from the validator's effective balance and the total number of active validators as follows: The base_reward represents the average reward received by a validator under optimal conditions per epoch.
This is the base unit that other rewards are calculated from. The value of the rewards in each epoch are calculated from a base_reward. Validators receive rewards when they make votes that are consistent with the majority of other validators, when they propose blocks, and when they participate in sync committees. The Beacon Chain’s incentive structure therefore pays for honesty and punishes bad actors.Īll rewards and penalties are applied once per epoch. The slashed validator’s ether slowly drains away across the exit period, but on Day 18 they receive a “correlation penalty” which is larger when more validators are slashed around the same time. These are “slashable” behaviors that result in the validator having some amount of ether (up to 1 ETH) burned before the validator is removed from the network, which takes 36 days. There are also some actions that are very difficult to do accidentally and signify some malicious intent, such as proposing multiple blocks for the same slot or attesting to multiple blocks for the same slot. Validators are also sometimes tasked with signature aggregation and participating in sync committees. If the validator fails to do either of these tasks when asked they miss out on an ether payout. There are two primary roles for a validator: 1) checking new blocks and “attesting” to them if they are valid, 2) proposing new blocks when selected at random from the total validator pool.

They are then paid in ether to run validator software that checks the validity of new blocks received over the peer-to-peer network and apply the fork-choice algorithm to identify the head of the chain. Node operators that wish to participate in validating blocks and identifying the head of the chain deposit ether into a smart contract on Ethereum. Ethereum is secured using its native cryptocurrency, ether (ETH).
