 For this two-client structure to work, consensus clients must be able to pass bundles of transactions to the execution client. Executing the transactions locally is how the client validates that the transactions do not violate any Ethereum rules and that the proposed update to Ethereum’s state is correct. Likewise, when the node is selected to be a block producer the consensus client must be able to request bundles of transactions from Geth to include in the new block and execute them to update the global state. This inter-client communication is handled by a local RPC connection using the [engine API](https://github.com/ethereum/execution-apis/blob/main/src/engine/common.md).
