Crate alloy_consensus 

alloy-consensus

Ethereum consensus interface.

This crate contains constants, types, and functions for implementing Ethereum EL consensus and communication. This includes headers, blocks, transactions, EIP-2718 envelopes, EIP-2930, EIP-4844, and more.

In general a type belongs in this crate if it is committed to in the EL block header. This includes:

• transactions
• blocks
• headers
• receipts
• EIP-2718 envelopes.

Provenance

Much of this code was ported from reth-primitives as part of ongoing alloy migrations.

Modules

conditional

Helpers for conditional transactions.

constants

Ethereum protocol-related constants

crypto

Cryptographic algorithms

error

Helper errors.

extended

Extended transaction types

proofs

Helper function for calculating Merkle proofs and hashes.

serde_bincode_compatserde and serde-bincode-compat

Bincode-compatible serde implementations for consensus types.

transaction

Transaction types.

utils

Utilities for working with EIP-4844 field elements and implementing SidecarCoder.

Structs

Account

Represents an TrieAccount in the account trie.

BlobTransactionSidecar

This represents a set of blobs, and its corresponding commitments and proofs.

Block

Ethereum full block.

BlockBody

A response to GetBlockBodies, containing bodies if any bodies were found.

Header

Ethereum Block header

HeaderInfo

Essential info extracted from a header.

Receipt

Receipt containing result of transaction execution.

ReceiptWithBloom

Receipt with calculated bloom filter.

Receipts

A collection of receipts organized as a two-dimensional vector.

Sealed

A consensus hashable item, with its memoized hash.

SidecarBuilder

Build a BlobTransactionSidecar from an arbitrary amount of data.

Signed

A transaction with a signature and hash seal.

SimpleCoder

Simple coder that only uses the last 31 bytes of each blob. This is the default coder for the SidecarBuilder.

TrieAccount

Represents an TrieAccount in the account trie.

Enums

BlobTransactionValidationErrorkzg

An error that can occur when validating a BlobTransactionSidecar::validate.

Eip658Value

Captures the result of a transaction execution.

EnvKzgSettingskzg

KZG settings.

ReceiptEnvelope

Receipt envelope, as defined in EIP-2718.

Constants

EMPTY_ROOT_HASH

Root hash of an empty trie.

Traits

BlockHeader

Trait for extracting specific Ethereum block data from a header

Eip2718EncodableReceipt

Receipt type that knows its EIP-2718 encoding.

EthBlock

A trait for ethereum like blocks.

RlpDecodableReceipt

Receipt type that knows how to decode itself with a Bloom value.

RlpEncodableReceipt

Receipt type that knows how to encode itself with a Bloom value.

Sealable

Sealeable objects.

SidecarCoder

A strategy for coding and decoding data into sidecars.

TxReceipt

Receipt is the result of a transaction execution.

Typed2718

A trait that helps to determine the type of the transaction.

Type Aliases

Blob

A Blob serialized as 0x-prefixed hex string

Bytes48

A commitment/proof serialized as 0x-prefixed hex string

Derive Macros

TransactionEnvelope

Derive macro for creating transaction envelope types.
