Expand description

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

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.
