Introduction

Types reused throughout the specification, which are specific to Ethereum.

Address

23
Address = Bytes20

Root

24
Root = Hash32

Bloom

19
Bloom = Bytes256

EMPTY_CODE_HASH

28
EMPTY_CODE_HASH = keccak256(b"")

Account

State associated with an address.

31
@slotted_freezable
32
@dataclass
class Account:

nonce

38
    nonce: Uint

balance

39
    balance: U256

code_hash

40
    code_hash: Hash32

EMPTY_ACCOUNT

43
EMPTY_ACCOUNT = Account(
44
    nonce=Uint(0),
45
    balance=U256(0),
46
    code_hash=EMPTY_CODE_HASH,
47
)

encode_account

Encode Account dataclass.

Storage is not stored in the Account dataclass, so Accounts cannot be encoded without providing a storage root.
