Introduction

Types re-used throughout the specification, which are specific to Ethereum.

Address

24
Address = Bytes20

Root

25
Root = Hash32

Bloom

27
Bloom = Bytes256

Account

State associated with an address.

@slotted_freezable
31
@dataclass
class Account:

nonce

37
    nonce: Uint

balance

38
    balance: U256

code

39
    code: bytes

EMPTY_ACCOUNT

42
EMPTY_ACCOUNT = Account(
43
    nonce=Uint(0),
44
    balance=U256(0),
45
    code=bytearray(),
46
)

encode_account

Encode Account dataclass.

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