add_receipt_to_header(old_header: eth.abc.BlockHeaderAPI, receipt: eth.abc.ReceiptAPI) → eth.abc.BlockHeaderAPI

Apply the receipt to the old header, and return the resulting header. This may have storage-related side-effects. For example, pre-Byzantium, the state root hash is included in the receipt, and so must be stored into the database.

classmethod calculate_net_gas_refund(consumed_gas: int, gross_refund: int) → int

static compute_difficulty(parent_header: eth.abc.BlockHeaderAPI, timestamp: int) → int

Computes the difficulty for a frontier block based on the parent block.

classmethod finalize_gas_used(transaction: eth.abc.SignedTransactionAPI, computation: eth.abc.ComputationAPI) → int

static get_block_reward() → int

Return the amount in wei that should be given to a miner as a reward for this block.

Note

This is an abstract method that must be implemented in subclasses

classmethod get_nephew_reward() → int

Return the reward which should be given to the miner of the given nephew.

Note

This is an abstract method that must be implemented in subclasses

static get_uncle_reward(block_number: int, uncle: eth.abc.BlockHeaderAPI) → int

Return the reward which should be given to the miner of the given uncle.

Note

This is an abstract method that must be implemented in subclasses

classmethod make_receipt(base_header: eth.abc.BlockHeaderAPI, transaction: eth.abc.SignedTransactionAPI, computation: eth.abc.ComputationAPI, state: eth.abc.StateAPI) → eth.abc.ReceiptAPI

Generate the receipt resulting from applying the transaction.

Parameters:

• base_header – the header of the block before the transaction was applied.
• transaction – the transaction used to generate the receipt
• computation – the result of running the transaction computation
• state – the resulting state, after executing the computation

Returns:

class eth.vm.forks.byzantium.ByzantiumVM(header: eth.abc.BlockHeaderAPI, chaindb: eth.abc.ChainDatabaseAPI, chain_context: eth.abc.ChainContextAPI, consensus_context: eth.abc.ConsensusContextAPI)

block_class

alias of eth.vm.forks.byzantium.blocks.ByzantiumBlock

add_receipt_to_header(old_header: eth.abc.BlockHeaderAPI, receipt: eth.abc.ReceiptAPI) → eth.abc.BlockHeaderAPI

Apply the receipt to the old header, and return the resulting header. This may have storage-related side-effects. For example, pre-Byzantium, the state root hash is included in the receipt, and so must be stored into the database.

static get_block_reward() → int

Return the amount in wei that should be given to a miner as a reward for this block.

Note

This is an abstract method that must be implemented in subclasses

classmethod make_receipt(base_header: eth.abc.BlockHeaderAPI, transaction: eth.abc.SignedTransactionAPI, computation: eth.abc.ComputationAPI, state: eth.abc.StateAPI) → eth.abc.ReceiptAPI

Generate the receipt resulting from applying the transaction.

Parameters:

• base_header – the header of the block before the transaction was applied.
• transaction – the transaction used to generate the receipt
• computation – the result of running the transaction computation
• state – the resulting state, after executing the computation

Returns:

receipt

classmethod validate_receipt(receipt: eth.abc.ReceiptAPI) → None

Validate the given receipt.

classmethod decode(encoded: bytes) → eth.abc.ReceiptAPI

This decodes a receipt that is encoded to either a typed receipt, a legacy receipt, or the body of a typed receipt. It assumes that typed receipts are not rlp-encoded first.

If dealing with an object that is always rlp encoded, then use this instead:

rlp.decode(encoded, sedes=ReceiptBuilderAPI)

For example, you may receive a list of receipts via a devp2p request. Each receipt is either a (legacy) rlp list, or a (new-style) bytestring. Even if the receipt is a bytestring, it’s wrapped in an rlp bytestring, in that context. New-style receipts will not be wrapped in an RLP bytestring in other contexts. They will just be an EIP-2718 type-byte plus payload of concatenated bytes, which cannot be decoded as RLP. This happens for example, when calculating the receipt root hash.

classmethod deserialize(encoded: Union[bytes, List[bytes]]) → eth.abc.ReceiptAPI

Extract a receipt from an encoded RLP object.

This method is used by rlp.decode(…, sedes=ReceiptBuilderAPI).

classmethod serialize(obj: eth.abc.ReceiptAPI) → Union[bytes, List[bytes]]

Encode a receipt to a series of bytes used by RLP.

In the case of legacy receipt, it will actually be a list of bytes. That doesn’t show up here, because pyrlp doesn’t export type annotations.

This method is used by rlp.encode(obj).

copy(*args, **kwargs) → eth.abc.ReceiptAPI

Return a copy of the receipt, optionally overwriting any of its properties.

classmethod decode(encoded: bytes) → eth.abc.ReceiptAPI

This decodes a receipt that is encoded to either a typed receipt, a legacy receipt, or the body of a typed receipt. It assumes that typed receipts are not rlp-encoded first.

rlp.decode(encoded, sedes=ReceiptBuilderAPI)

eth.vm.forks.berlin.transactions module

class eth.vm.forks.berlin.transactions.AccessListPayloadDecoder

Bases: eth.abc.TransactionDecoderAPI

classmethod decode(payload: bytes) → eth.abc.SignedTransactionAPI

This decodes a transaction that is encoded to either a typed transaction or a legacy transaction, or even the payload of one of the transaction types. It assumes that typed transactions are not rlp-encoded first.

If dealing with an object that is rlp encoded first, then use this instead:

rlp.decode(encoded, sedes=TransactionBuilderAPI)

For example, you may receive a list of transactions via a devp2p request. Each transaction is either a (legacy) rlp list, or a (new-style) bytestring. Even if the transaction is a bytestring, it’s wrapped in an rlp bytestring, in that context. New-style transactions will not be wrapped in an RLP bytestring in other contexts. They will just be an EIP-2718 type-byte plus payload of concatenated bytes, which cannot be decoded as RLP. An example context for this is calculating the transaction root hash.

class eth.vm.forks.berlin.transactions.AccessListTransaction(*args, **kwargs)

Bases: rlp.sedes.serializable.Serializable, eth.rlp.transactions.SignedTransactionMethods, eth.abc.SignedTransactionAPI

check_signature_validity() → None

Check if the signature is valid. Raise a ValidationError if the signature is invalid.

encode() → bytes

This encodes a transaction, no matter if it’s: a legacy transaction, a typed transaction, or the payload of a typed transaction. See more context in decode.

get_intrinsic_gas() → int

Return the intrinsic gas for the transaction which is defined as the amount of gas that is needed before any code runs.

get_message_for_signing() → bytes

Return the bytestring that should be signed in order to create a signed transaction.

get_sender() → NewType.<locals>.new_type

Get the 20-byte address which sent this transaction.

This can be a slow operation. transaction.sender is always preferred.

make_receipt(status: bytes, gas_used: int, log_entries: Tuple[Tuple[bytes, Tuple[int, ...], bytes], ...]) → eth.abc.ReceiptAPI

Build a receipt for this transaction.

Transactions have this responsibility because there are different types of transactions, which have different types of receipts. (See access-list transactions, which change the receipt encoding)

Parameters:

• status – success or failure (used to be the state root after execution)
• gas_used – cumulative usage of this transaction and the previous ones in the header
• log_entries – logs generated during execution

eth.vm.forks.london.constants module

eth.vm.forks.london.headers module

class eth.vm.forks.london.headers.LondonBackwardsHeader

Bases: eth.abc.BlockHeaderSedesAPI

An rlp sedes class for block headers.

It can serialize and deserialize both London and pre-London headers.

classmethod deserialize(encoded: List[bytes]) → eth.abc.BlockHeaderAPI

Extract a header from an encoded RLP object.

This method is used by rlp.decode(…, sedes=TransactionBuilderAPI).

classmethod serialize(obj: eth.abc.BlockHeaderAPI) → List[bytes]

Encode a header to a series of bytes used by RLP.

This method is used by rlp.encode(obj).

get_gas_price(transaction: eth.abc.SignedTransactionAPI) → int

Return the gas price of the given transaction.

Factor in the current block’s base gas price, if appropriate. (See EIP-1559)

get_tip(transaction: eth.abc.SignedTransactionAPI) → int

Return the gas price that gets allocated to the miner/validator.

Pre-EIP-1559 that would be the full transaction gas price. After, it would be the tip price (potentially reduced, if the base fee is so high that it surpasses the transaction’s maximum gas price after adding the tip).

get_transaction_context(transaction: eth.abc.SignedTransactionAPI) → eth.abc.TransactionContextAPI

London-specific transaction context creation, where gas_price includes the block base fee

validate_transaction(transaction: eth.abc.SignedTransactionAPI) → None

Validate the given transaction.

base_fee

Return the current base_fee from the current execution_context

Raises a NotImplementedError if called in an execution context prior to the London hard fork.

class eth.vm.forks.london.state.LondonTransactionExecutor(vm_state: eth.abc.StateAPI)

Bases: eth.vm.forks.berlin.state.BerlinTransactionExecutor

build_evm_message(transaction: eth.abc.SignedTransactionAPI) → eth.abc.MessageAPI

Build and return a MessageAPI from the given transaction.

classmethod calculate_gas_refund(computation: eth.abc.ComputationAPI, gas_used: int) → int

eth.vm.forks.london.storage module

eth.vm.forks.london.transactions module

class eth.vm.forks.london.transactions.DynamicFeePayloadDecoder

Bases: eth.abc.TransactionDecoderAPI

classmethod decode(payload: bytes) → eth.abc.SignedTransactionAPI

This decodes a transaction that is encoded to either a typed transaction or a legacy transaction, or even the payload of one of the transaction types. It assumes that typed transactions are not rlp-encoded first.

If dealing with an object that is rlp encoded first, then use this instead:

rlp.decode(encoded, sedes=TransactionBuilderAPI)

For example, you may receive a list of transactions via a devp2p request. Each transaction is either a (legacy) rlp list, or a (new-style) bytestring. Even if the transaction is a bytestring, it’s wrapped in an rlp bytestring, in that context. New-style transactions will not be wrapped in an RLP bytestring in other contexts. They will just be an EIP-2718 type-byte plus payload of concatenated bytes, which cannot be decoded as RLP. An example context for this is calculating the transaction root hash.

class eth.vm.forks.london.transactions.DynamicFeeTransaction(*args, **kwargs)

Bases: rlp.sedes.serializable.Serializable, eth.rlp.transactions.SignedTransactionMethods, eth.abc.SignedTransactionAPI

check_signature_validity() → None

Check if the signature is valid. Raise a ValidationError if the signature is invalid.

encode() → bytes

This encodes a transaction, no matter if it’s: a legacy transaction, a typed transaction, or the payload of a typed transaction. See more context in decode.

get_intrinsic_gas() → int

Return the intrinsic gas for the transaction which is defined as the amount of gas that is needed before any code runs.

get_message_for_signing() → bytes

Return the bytestring that should be signed in order to create a signed transaction.

get_sender() → NewType.<locals>.new_type

Get the 20-byte address which sent this transaction.

This can be a slow operation. transaction.sender is always preferred.

make_receipt(status: bytes, gas_used: int, log_entries: Tuple[Tuple[bytes, Tuple[int, ...], bytes], ...]) → eth.abc.ReceiptAPI

Build a receipt for this transaction.

Transactions have this responsibility because there are different types of transactions, which have different types of receipts. (See access-list transactions, which change the receipt encoding)

Parameters:

• status – success or failure (used to be the state root after execution)
• gas_used – cumulative usage of this transaction and the previous ones in the header
• log_entries – logs generated during execution
