There are two different types of ETH rewards.
Consensus layer (CL) rewards consist of new issuance from attestations, block proposals, and sync committee participation. Including evidence of slashable events in a block is also a source of CL rewards. Even though on a per block basis the rewards for proposing are much higher, over the long term, the vast majority of CL rewards come from attestations.
Execution layer (EL) rewards are received by validators only when they are proposing blocks, which is a random and infrequent event. EL rewards include MEV rewards and tips (i.e., priority fees).
The CL rewards account for the majority of the rewards in the second quarter of 2023 at ~68% compared to ~32% for EL rewards. Check out our Ethereum Validator Insights Q2 2023 Report here.
