Expand description

Represents a message in the eth wire protocol, versions 66, 67, 68 and 69.

The ethereum wire protocol is a set of messages that are broadcast to the network in two styles:

  • A request message sent by a peer (such as GetPooledTransactions), and an associated response message (such as PooledTransactions).
  • A message that is broadcast to the network, without a corresponding request.

The newer eth/66 is an efficiency upgrade on top of eth/65, introducing a request id to correlate request-response message pairs. This allows for request multiplexing.

The eth/67 is based on eth/66 but only removes two messages, GetNodeData and NodeData.

The eth/68 changes only NewPooledTransactionHashes to include types and sized. For it, NewPooledTransactionHashes is renamed as NewPooledTransactionHashes66 and NewPooledTransactionHashes68 is defined.

The eth/69 announces the historical block range served by the node. Removes total difficulty information. And removes the Bloom field from receipts transferred over the protocol.

The eth/70 (EIP-7975) keeps the eth/69 status format and introduces partial receipts. requests/responses.

The eth/71 draft extends eth/70 with block access list request/response messages.

Variants§

§

Represents a NewBlockHashes message broadcast to the network.

§

NewBlock(Box<N::NewBlockPayload>)

Represents a NewBlock message broadcast to the network.

§

Transactions(Transactions<N::BroadcastedTransaction>)
