Ethereum’s transition to proof-of-stake is like altering the engine of a transferring automotive, the place the automotive is the execution layer (EL) that processes the info and transactions and the engine is the consensus layer (CL) that determines how the transactions are constructed into blocks to make the chain. Due to this, Ethereum has execution shoppers (at the moment a selection of 4) and consensus shoppers (at the moment a selection of 5) that may be blended and matched to allow safety of the chain.
