This PR implements EIP-7702: "Set EOA account code". Specification: https://eips.ethereum.org/EIPS/eip-7702 > Add a new transaction type that adds a list of `[chain_id, address, nonce, y_parity, r, s]` authorization tuples. For each tuple, write a delegation designator `(0xef0100 ++ address)` to the signing account’s code. All code reading operations must load the code pointed to by the designator. --------- Co-authored-by: Mario Vega <marioevz@gmail.com> Co-authored-by: Martin Holst Swende <martin@swende.se> Co-authored-by: Felix Lange <fjl@twurst.com> |

Difficulty calculation
This test shows how the evm t8n can be used to calculate the (ethash) difficulty, if none is provided by the caller.
Calculating it (with an empty set of txs) using London rules (and no provided unclehash for the parent block):
[user@work evm]$ ./evm t8n --input.alloc=./testdata/14/alloc.json --input.txs=./testdata/14/txs.json --input.env=./testdata/14/env.json --output.result=stdout --state.fork=London

Same thing, but this time providing a non-empty (and non-emptyKeccak) unclehash, which leads to a slightly different result:
