Beacon Chain Attestation Rewards

The majority of a validator’s rewards come from making attestations. While assigning committees and slots is randomized, each active validator is guaranteed to make one attestation per epoch. Validators earn rewards for attestations only when included in Beacon Chain blocks. Each attestation consists of three votes, with rewards based on the following criteria:

Inclusion of the attestation with the correct source checkpoint within 5 slots
Inclusion of the attestation with the correct target checkpoint within 32 slots
Inclusion of the attestation with the correct head block within 1 slot

More on Beacon Chain Attestation rewards

Attestation rewards for Beacon chain are split up into two separate tables. Both tables are retrieved from /eth/v1/beacon/rewards/attestations/{epoch} RPC Method.

Table Name	Description
`beacon.raw.attestation_rewards_daily`	Table that aggregates the total reward metrics for individual validators by day.
`beacon.raw.total_rewards`	Table containing total reward metrics for individual validators in the specified epoch. This table returns the total number of active, ongoing validators in each Epoch. Note: this table size is large. Expect that query performance to be slow. It increases by about 225 epoch * # active validators ~ 250m+ rows in size daily.
`beacon.raw.ideal_rewards`	Table containing ideal reward metrics for attestations in the specified epoch. Currently, there (as of Epoch 289619), there are always 32 rows for each epoch, each for effective balance (1 to 32 ETH) of ETH staked.

Attestation Rewards Daily

Attestation reward rewards collected by validator aggregated by day from beacon.raw.total_rewards. Note that attestation does not include sync committee rewards. For each validator, there is only entry daily.

Column Name	Description	Example
Date	Date	288389
validator Index	Validator Index	1296908
min_epoch	The lowest Epoch number that the validator started attesting	287663
max_epoch	The largest Epoch number that the validator started attesting	287887
epoch_count	Number of unique epochs that the validator participated in for attestation within the day.	225
head	The sum reward for attesting to the head block for the specified validator	534132
target	The sum reward for attesting to the target block for the specified validator	1034226
source	The sum reward for attesting to the source block for the specified validator	552116
inclusion_delay	(Optional) The sum reward for including the attestation in a block with a specific delay for the specified validator	0
inactivity	(Optional) The inactivity penalty for the total reward calculation for the specified validator	0
total_rewards	The sum of rewards across head, target, source, inclusion_delay and inactivity.	2120474
