 While the consensus `ExecutionPayloadHeader` and the execution block header map to each other conceptually, they are encoded differently. This EIP aims to align the encoding of the `transactions_root`, taking advantage of the more modern SSZ format. This brings several advantages:
 
-1. **Transaction inclusion proofs:** Changing the transaction representation to [EIP-6493 `SignedTransaction`](./eip-6493.md) commits to the transaction root hash on-chain, allowing verification of the list of all transaction hashes within a block, and allowing compact transaction inclusion proofs.

 2. **Reducing complexity:** The proposed design reduces the number of use cases that require support for Merkle-Patricia Trie (MPT), RLP encoding, keccak hashing, and secp256k1 public key recovery.

 While a unique transaction identifier `tx_hash` is defined for each transaction, there is no on-chain commitment to this identifier for RLP transactions.
